What are the commonly used chemicals products?
Chemicals products are mainly divided into four categories: inorganic chemical products, organic chemical products, biochemical products and fine chemical products.
Inorganic chemical products include sulfuric acid, nitric acid, hydrochloric acid, phosphoric acid, caustic soda, soda ash, synthetic ammonia and various inorganic salts.
Organic chemical products are mainly products derived from coal chemical and petrochemical products, such as alkanes and aromatics, specifically methane, ethane, formaldehyde, acetaldehyde, formic acid, acetic acid, benzene, toluene, xylene , Benzenesulfonic acid, phenylacetic acid, nitrobenzene, aniline, phenol, acetone, ethanol, etc.
Biochemical products include starch sugar, amino acid food additives derived from fermentation, antibiotic pharmaceutical products, etc.
Fine chemical products include dyes, pigments, spices, rubber additives, plastic additives, printing and dyeing textile papermaking additives, water treatment agents, oilfield and mining additives, etc.

What are chemical products?
Chemicals products refer to products that use chemical methods to change the composition and structure of substances or to synthesize new substances. Chemicals products contain: erucic acid, vegetable oleic acid, arachidic acid, behenic acid, arachidic acid, oleic acid, stearic acid, palmitic acid, tridecane dibasic acid, azelaic acid, nonanoic acid, black oleic acid, mixed Fatty Acids, Erucyl Alcohol, Oleyl Alcohol, Behenyl Alcohol, Eicosanol, Natural Octacosyl Alcohol, Synthetic Jojoba Oil, Cetyl Esters, Musk, Glycerin, Glyceryl Behenate.

Commonly used chemicals products.
1. Scouring agent: It has the functions of penetration and cleaning, and can effectively remove fiber oil, wax and other impurities
2. Penetrating agent: it has quite strong penetrating power, which can quickly and evenly moisten and penetrate.
3. Metal ion complexing agent (metal ion blocking agent): strong blocking ability and strong dispersing effect on heavy metal ions such as calcium magnesium iron.
4. Hydrogen peroxide:
The scientific name hydrogen peroxide is an excellent bleaching agent, but its damage to cotton fibers is higher than that of sodium hypochlorite bleaching, and its weight loss is also less.
Hydrogen peroxide bleaching has lower requirements for fabric desizing and scouring than continuous scouring and bleaching.
Usually fabrics are bleached with hydrogen peroxide at 80-100°C, which is more expensive than bleaching with sodium hypooxide. It is suitable for high-end and high-quality products. The bleaching of hydrogen peroxide should be carried out in an alkaline solution with a pH value of 10-11. The degree and strength obtained in this way are high. Hydrogen peroxide is also commonly used for bleaching silk fabrics. Hypochlorite bleaching is not suitable because it can chlorinate silk fabrics and damage silk. Hydrogen peroxide is also used as a wool bleaching agent. Hypochlorite cannot be used for wool bleaching, because it will damage the fiber and cause yellowing, and it is difficult to obtain long-lasting whiteness.
5. Hydrogen peroxide stabilizer: It can effectively inhibit the decomposition of hydrogen peroxide, and usually protect fibers from brittleness during oxygen bleaching.
6. Caustic soda (NaOH):
It is a strong alkali that can be used as a desizing agent and scouring agent for cotton yarn and cotton cloth. It can effectively remove grease or other impurities in cotton fibers. Caustic soda can also be used for mercerizing cotton fibers. Treated with concentrated caustic soda solution to obtain silk-like luster.
