Maltodextrin in food industry

Maltodextrin is a starch food additives, it often act as a thickener or filler for production of commercial foods and beverages. Although it is almost tasteless, but it is often described as slightly sweet taste. Most nutrition experts agree that this material is a "zero" sum, meaning low calories, vitamins or other nutrients. It is mostly used in bulk products to increase and improve the texture and appearance. Maltodextrin is a common ingredient in sports drinks, and human body digest it as a simple carbohydrate. Some studies have shown that maltodextrin supplement can help maintain the anaerobic capacity during exercise. However, there are other studies show no effect.

The process of maltodextrin is a little more complicated. Chemists usually starts from the natural starch, in addition to the most common potatoes, there are also corn, wheat and barley. Starch must reduce the basic components, usually mixed with water in hydrolysis process. Even further by removing proteins and other components using an enzyme. Finally it get a product that is almost tasteless and white powder dissolves instantly in water.

It is one of the most common uses for malt dextrin used as a food additive to increase products viscosity. Because of the colorless, it is used in cereal, salad dressing, business volume of sauces and other food. Maltodextrin can form a gel structure and withholding water, it may have a similar texture and taste of fat when the DE value is 3~5, so it is a good fat substitutes. It is a substitutes of ice-cream, salad, sausages and other fat.

The FDA generally accepted maltodextrin are safe. There are malt dextrin, starch sweeteners in many processed foods and beverages, proper amount use may have little impact on human health, however, diabetic patients or people who need to monitor blood sugar levels should pay attention to this component. Most malt dextrin is gluten-free, even wheat or barley products are made so. This is because the finishing process removes almost all colloidal components. Even so, wheat allergy or celiac disease patients still need to avoid foods that contain this thickening agent.
But maltodextrin can be used as a simple carbohydrate intake, for it is easily to turn into instant energy. Therefore, this compounds are popular among players, and it is the ingredient of many sports drinks. If you have interest to okchem, click here, thanks!

Sulphur black in dyeing

Sulphur black dye is insoluble in water, so sulfur dyes does not have dyeing capacity to cotton. But its in the sodium sulfide of aqueous reduced to leuco dyes for dyeing of cotton with good performance. So sulfur dyes are to be carried out in a solution of sodium sulfide. Sulphur black dye is more sulfur-containing polymer, which contain sulfur and disulfide bonds in the structure, but it is very unstable. Particularly the sulfur bonds in certain temperature and humidity conditions can be oxidized by the oxygen in the air as sulphur oxides, and further with water molecules in the air to produce sulfuric acid, thus reduce the yarn and fibre tendering, seriously fibers may all brittle into powders.
 
 
Sulphur black of cotton knit fabrics are difference from reactive black. First the two ingredients are different, the primary compose of reactive black is carbon, and sulfur black dye containing more sulfur, though their color is closer. Secondly, their uses are not the same, active black mainly used as adsorption materials, such as desiccant and air purification, while sulphur black are mostly used in dyeing of textiles.

Na2S is solvent to dissolve sulfur dyes, its role is to restore the sulfur black dye with leuco dye on cotton. Na2CO3 increase reduction stability role in sulfur black dye preventing dyes premature oxidation. It prevents the effects of calcium and magnesium salts in hard water staining when using hard water stain. General amount is 2% of the fabric, excessive amount may make fabric Red-Brown. Add Na2SO4 in dye solution are helpful to improve the dyeing.

But there are some notes in the operation.
1 to ensure time and temperature, ensure that the dye dissolve fully restored.
2 guarantee the temperature and time of germ cloth oil removal, removing grease from cloth to improve capillary effect and stain evenly.
3 wash water oxidation is the key.
4 soft: soft oil in the cylinder with water of 1:20

Environment-friendly liquid sulphur black mainly used in the denim yarn dyeing, cloth dyeing, knitting dyeing, package dyeing and so on. Compared with the activity, petroleum jelly and other dyes for cotton, it has the advantages of low cost and short process. And it has been increasingly accepted by the printing and dyeing factories.

Hydrofluoric acid uses and tips

Because of the ability to dissolve oxides, hydrofluoric acid plays an important role in the purification of aluminum and uranium. It has many uses, for example, hydrofluoric acid is used to etch the glass, carve, tag and text; semiconductor industry uses it to remove oxides on the silicon surface; it can be used as isobutane and butene alkylation catalyst in refinery; etc. Hydrofluoric acid is also used for a variety of synthesis of fluorine-containing organic compounds, such as Teflon (PTFE) and refrigerants like freon.

Hydrofluoric acid is the aqueous solution of hydrogen fluoride, clear, colorless, corrosive liquid smoke, intense unpleasant smell. -83.3 degrees melting point, boiling point of 112.2 ℃, density 0.888g/cm ³. Because hydrogen and fluorine atoms combined capacity is relatively strong, this makes hydrofluoric acid in the water not fully ionized, so in theory a low concentration of hydrofluoric acid is a weak acid. It is highly corrosive, acutely corrosive action on metals, glass and Silicon-containing objects. Laboratory general use of Fluorite (composed mainly of calcium fluoride) and concentrated sulfuric acid to produce, and it needs to be sealed in a plastic bottle and kept in the shade.

Recently, the anhydrous hydrofluoric acid market slightly downward. At present, fluorite powder upstream of hydrofluoric acid market is less than the beginning of the month, price has made many callbacks, domestic sulfuric acid market continues weak. This is only for reference.
The main ingredient of fluorspar is calcium fluoride (CaF2), it is the base and source of fluorine chemical industry as a whole. According to United States Geological Survey data, fluorite resources in global distribution is relatively concentration, the major producer are South Africa, Mexico, Mongolia, China, Russia, the United States, Thailand, Spain and other countries. As HF production depends on fluorite resources, so the enterprises concentrate in East China the rich fluorite resources places. From the late 20th century to 2010, due to the control of fluorite resources in China and the rapid rise of the fluorine chemical industry, this led to the development of hydrofluoric acid and its downstream products, Chinese exports of fluoride products rapidly.

Emergency treatment of HF spill is to evacuate personnel to safe areas, isolation and strict restrictions on access. Recommended emergency personnel wear positive pressure self-contained breathing apparatus, and wear anti-acid clothes. Cut off the source of the leak as possible to prevent them from entry into sewers, drainage ditches and other restricted spaces. If a small amount of leak, mix sand, dry lime and soda ash. Also large amounts of flushing water is available, pour them into the wastewater system after wash water diluted. If you want to get more details about okchem, please click here!

Uses of linear alkyl benzene sulfonate (LAS)

Linear alkyl benzene sulfonate (LAS) is widely used in the detergent industry, as well as a very high performance-price ratio of surfactant. After nearly 40 years of testing and practical application shows that LAS has been recognized internationally on environmental and human security.

Linear alkyl benzene sulfonic acid sodium can purified into the hexagonal top or rhomboid crystals, minimal toxicity, and international security organization has identified it as a safe chemical raw material, it can be applied to fruits and tableware washing. Sodium alkyl benzene sulfonate are commonly used in the detergent. Because of the large-scale automated production, it is low prices. Linear alkyl benzene sulfonic acid sodium salt in the detergent is divided into branched chains (ABS) and straight-chain structure (LAS). Biodegradability of branched chains is small and may do harm to environment, but straight-chain structure is easily biodegradable, its biodegradation may be greater than 90% and less environmental pollution.

But people pay more attention to the real environment, data of the United States, and Canada and Germany active wastewater treatment plant shows that the removal rate of LAS is 96%~99%. Some researchers found that LAS degradation is very quickly in the groundwater, deep in the infiltration points over 600m not measured LAS. Researchers also found that C13LAS biodegradation half-life is 1-2 days.
Linear alkyl benzene sulfonate is not only the most important variety of anionic surfactant, but also the main kinds of detergent actives. It has strong detergency, bubble and foam stability, it has good stability in solution of acidic, alkaline and certain antioxidants, such as sodium hypochlorite, peroxide, etc. Therefore, it is a quality detergents and foaming agents.

Linear alkyl benzene sulfonic acid sodium salt is neutral, it is more sensitive to water hardness, not easy to oxidation, strong foaming ability, low cost, higher detergency and easily compounded with various additives. They are excellent surfactants. In recent years, LAS always use with non-ionic surfactant such as AEO for better integrated washing results. The main purpose of LAS is the preparation of various types of liquid, powdered, granulated detergents, cleaners and detergents. It is safe to the environment and humans. Due to the nature of LAS, it still have very broad application prospects in a long period in the future. Read more here!

Flake fillers form a parallel alignment in the film, water and other corrosive substances on film penetrated has strong barrier, permeability resistance increased 3 times, then anti-corrosion Coatings, exterior wall paints and related coatings performance improved significantly.

Sericite powders are important to anticorrosion coatings. As to outdoor coatings and exterior wall coatings, rain and UV damage should take into consideration. The infiltration of rain water will reduce the intensity of the film and accelerate aging, also it forms the porous structure within the paint film after frozen, the acid dissolves fillers (such as calcium carbonate), these problems have to be solved by adding MICA powder. MICA absorb UV light, high cover and shielding, so it can further delay the aging of coating. In addition, flaky filling has an enhanced role on film.

The insulation properties of improve coatings is one of application of sericite powder, this MICA powder should not contain conductive impurities such as free iron oxide. Infrared radiation is one of MICA functions, good high temperature resistance (available at 800-1200 work properly), so the infrared heating element and coating for high temperature equipment often need MICA powder as filler.

Conductive MICA powder is a new conductive filler of conductive paint. It is made by the flaky structure of natural MICA powder as base material in its surface package covered a layer or several layer chemical performance stable, strong resistance corrosion and high conductivity rate of conductive material. It is widely applied to anti-electrostatic paint, electromagnetic shield paint, antistatic industrial floor, explosion-proof buildings antistatic facilities, anti-electrostatic paint, anti-electrostatic latex paint, PVC anti-electrostatic floor, ring oxygen artesian flat anti-electrostatic paint, etc. Click here to get more!

A diversified application of graphene

Graphene as resin composite additive has good market prospects with high specific strength, modulus, fatigue resistance and damping performance. There are two main advantages of using graphene in ink: one is strong compatibility, graphene ink can achieve printing in plastic film, paper and the metal foil tablets, and variety base material; the conductive performance is better than carbon base material, while its cost lower than Nano metal conductive ink, such as Nano Silver and nano Copper powder. Compared to Nano Silver, the cost of graphene conductive ink can reduced 30%.

Graphene can be widely applied to various fields for it has thin, super strength characteristics, such as ultra light bullet-proof vests, ultra-thin ultralight materials, and so on. According to its excellent electrical conductivity, it also has great potential in the field of microelectronics. Graphene maybe a possible alternative to silicon to manufacture miniature transistor. Besides, graphene material is a good modification agent. Because of its high conductivity and high surface area in new energy field, it may be useful as an electrode material AIDS.

Graphene has a diversified application in lithium ion battery, currently it used as conductive additives in cathode material to improve electrode material of conductive performance, magnification performance and cycle life. Added 2% graphene can make phosphate iron lithium pole pieces of resistance rate reduce to 1 ω cm. This is far over the effect of equal quality proportion of carbon nano tube or conductive carbon black.

Graphene oxide has great effective on inhibiting the growth of Escherichia coli, and it will not harm human cells. If graphene oxide also has antibacterial activity on other bacteria, then a range of new applications may be found. Studies have shown that Graphene filters may be substantially more than other desalination technologies. As Graphene can modify chemistry capabilities, large contact area, foot-inch thickness of the atom, molecular gate structure, it can be be used in bacteria detection and diagnosis devices.

The unique two-dimensional structure of graphene makes it has a bright prospect in the field of sensor. Single Atom adsorption and release process can be directly observed by transmission electron microscope. By measuring the Hall effect can be indirectly detected a single atom of adsorption and release process. When a gas molecule is adsorbed on the graphite surface, adsorption sites will occur localized change in electricity resistance. Of course, this effect also occurs in other substances, but graphene has a high conductivity and low-noise quality, as well as capable of detecting small changes in resistance. Read more here!

Some introduction of adhesive

Adhesives can be used for metal, glass, wood, paper, fiber, rubber, plastic and other materials bonded together, it has a rapid development and widely applications, as well as a significant impact on the improving of high-tech science and technology progress and people's daily lives. Therefore, the research, development and production of various types of adhesives are very important.

Polysiloxane (silicone oil) used in cosmetic

Polysiloxane has been called silicone in history, and silicone can also occur in certain situations, such as catalogs. In China, silane monomers and siloxane compounds are known collectively as Silicones, and polysiloxane liquid is called silicone, polysiloxane rubbers is called silicone, and called polysiloxane resins as silicone resins.

Role of polysiloxane

New cosmetic formulations are almost contain silicone compounds, and silicone compounds in personal care products have achieved remarkable growth. Siloxane polymers composed of different kinds of compounds, including traditional silicone oils, water soluble polymers, oil-soluble polymer solubility, soluble fluoride polymer and a variety of polymers. They exist in various forms, from low viscosity fluids to flexible elastomer and synthetic resins.

Silicone as surfactant is growing popularity in recent years. Especially in cosmetic, because of its excellent performance of smooth, soft and bright, elegant, it is loved by a vast number of consumers. Siloxane-containing skin care, skin cleansers, hair care, shampoo, perfume, lipstick, toothpaste, etc products are being recognized, and modified silicone surfactants have been developed and applied.

Silicone surfactant for its physical inertia, chemical stability, it is no smelly, nontoxic, chemical degradation, not accumulated, no allergy, lower of surface tension, strong of anti-water, it can formed uniform waterproof breathable and lubrication performance good of protection film in skin surface, this makes silicon oil get quickly development in the application of cosmetics. So it can be used in various cosmetics such as cream cream, emulsion, wash surface milk, lipstick, dry sliding dual-use powder cake, added fat powder, shampoo, nursing sent pigment, mousse and stereotypes Hairspray, skin care, nursing sent, beauty, and salon, etc.

Consumers in their daily lives demand for nursing homes hair gradually enriched and improved, such as the demand for hair moisturizing daily nursing care. Because silicone has a very low surface tension, evenly on the hair surface forms a thin protective layer to prevent water evaporation in the hair, it forms a moisturizing hair mask ingredients. The hair moisturizing technology of polysiloxane can bring no frizz and soft effect.

Application of microencapsulation develops a more convenient way of silicone oil use, compound silicone oil and other conditioning moisturizing ingredients are made into microcapsules, adding it to a regular shampoo, it achieved the high-end performance shampoo, and it significantly reduces cost and simplifies the production process.

In addition, continuous improvement over the existing technology to get a new silicone, the development of high performance silicone, making it both rational adjustment, moisturizing, antibacterial sterilization, UV-resistant, and other special needs will also be the future research directions.

The production and application of fatty acid

Fatty acid is a carboxylic acid compounds composed of carbon and hydrogen from hydrocarbon groups link posed by the carboxyl group. The main component of fat is triglycerides formed by three long chain fatty acids and glycerol. Lower fatty acid is a colorless liquid with pungent, fatty acids are of high waxy solid with no obvious smell odors. Fatty acids are the simplest form of fat, it is a lot more complex lipid composition. In case of adequate oxygen supply, fatty acids oxidate to CO2 and H2O and release large amounts of energy.

Fatty acids can be used in production of styrene-butadiene rubber emulsifiers and surfactants, lubricants, Polish, it also can be used to produce the high SOAP and transparent SOAP and stearic acid and various surfactant intermediates. Fatty acids are mainly from natural oils, paraffin wax oxidation or pine in waste paper recovery obtained by distillation of tall oil. At present, the natural plant and animal oils and fats by hydrolysis, distillation in the production of fatty acids accounted for more than 4/5 of total fatty acid, it is the world's main source of fatty acids.

There are more than 40 different types of fatty acids in nature, which are key components of lipids. Many lipids physical properties depend on the saturated of fatty acids and carbon chain length, but only even number of carbon atoms of the fatty acid can be absorbed by human. Fatty acids can be classified according to their structure, the nutrition angle or its nutritional value to the human body. According to the classification of different carbon chain length, it can be divided into short-chain (2~4-containing atoms of carbon) fatty acids; medium-chain (6~12-containing carbon atoms) and long chain fatty acids (with more than 14 carbon atoms) fatty acid fatty acid classes.

Southeast Asia is rich in Palm oil and coconut oil. Palm kernel oil and coconut oil is to provide raw material for production of C8-14 fatty acids, they are mainly used for the production of surfactants. Palm oil is to provide raw material for production of C16-18 fatty acids, mainly for the production of stearic acid and its salts and esters, cationic surfactants and plastic additives.

Production of fatty acids present is mainly use Palm oil, cotton seed oil, cottonseed oil and canola oil as raw material. Fatty acids are important raw materials of organic chemicals and fine chemical, the downstream derivatives produced by fatty acids are widely used in textile printing and dyeing, food, medicine, daily chemical, petroleum, chemical, rubber and plastics processing, mining, transportation, foundry, metal processing, inks, paints and pigments industry.
