Fluorescent Whitening Agent (FWA)
It is a compound with a very high quantum efficiency, in the order of 1 million to 100,000 parts, which can effectively whiten natural or white substrates (such as textiles, paper, plastics, coatings). It can absorb the violet light with a wavelength of 340-380nm and emit blue light with a wavelength of 400-450nm, which can effectively make up for the yellowing caused by the blue light defect of white materials. It can improve the whiteness and brightness of the white material. The fluorescent whitening agent itself is colorless or light yellow (green) color, and is widely used in papermaking, textile, synthetic detergent, plastics, coatings and other industries at home and abroad. There are 15 basic structural types and nearly 400 chemical structures of fluorescent whitening agents that have been industrialized.

Sodium Bicarbonate
Inorganic compound, white crystalline powder, odorless, salty, soluble in water. It is slowly decomposed in humid air or hot air, producing carbon dioxide, which is completely decomposed when heated to 270 ° C. When exposed to acid, it breaks down strongly, producing carbon dioxide.
-
Sodium Sulfite
Sodium sulfite, white crystalline powder, soluble in water, insoluble in ethanol. Insoluble chlorine and ammonia are mainly used as artificial fiber stabilizer, fabric bleaching agent, photographic developer, dye bleaching deoxidizer, fragrance and dye reducing agent, lignin removal agent for paper making.

Acetic acid
It is an organic monic acid, the main component of vinegar. Pure anhydrous acetic acid (glacial acetic acid) is a colorless hygroscopic liquid, its aqueous solution is weakly acidic and corrosive, and it is strongly corrosive to metals.
-
Active Poly Sodium Metasilicate
It is an efficient, instant phosphorus free washing aid and an ideal substitute for 4A zeolite and sodium tripolyphosphate (STPP). Has been widely used in washing powder, detergent, printing and dyeing auxiliaries and textile auxiliaries and other industries.

Sodium Alginate
It is a by-product of extracting iodine and mannitol from kelp or sargassum of brown algae. Its molecules are connected by β-D-mannuronic acid (β-D-Mannuronic acid, M) and α-L-guluronic acid (α-l-Guluronic acid, G) according to the (1→4) bond. It is a natural polysaccharide. It has the stability, solubility, viscosity and safety required for pharmaceutical excipients. Sodium alginate has been widely used in food industry and medicine.

Formic acid
A colorless liquid with a pungent odor. Formic acid is a weak electrolyte, one of the basic organic chemical raw materials, widely used in pesticides, leather, dyes, medicine and rubber industries. Formic acid can be directly used in fabric processing, tanning leather, textile printing and dyeing and green feed storage, and can also be used as metal surface treatment agent, rubber auxiliary and industrial solvent.
-
Aluminium sulfate
It can be used as flocculant in water treatment, retention agent in foam fire extinguisher, raw material for making alum and aluminum white, raw material for oil decolorization, deodorant and medicine, etc. In paper industry, it can be used as precipitating agent for rosin gum, wax emulsion and other rubber materials, and can also be used to make artificial gems and high-grade ammonium alum.
-
Ferric chloride
Soluble in water and strongly absorbent, it can absorb moisture in the air. The dye industry is used as an oxidant in the dyeing of indycotin dyes, and the printing and dyeing industry is used as a mordant. The organic industry is used as a catalyst, oxidant and chlorination agent, and the glass industry is used as a hot colorant for glassware. In sewage treatment, it plays the role of purifying the color of sewage and degrading oil.
