Sulfur dioxide pulse is a new and environmentally friendly product instead of insurance powder, with strong reducibility, obvious effect, good thermal stability, convenient storage and transportation, etc. Features, but also in the use of environmental protection and pollution-free.
Sodium percarbonate is an environmentally friendly, high-performance low-temperature oxygen bleaching agent, and is widely used in industry as well as in daily life.
Thiourea is the main raw material for the production of sulfur dioxide pulse. It is also widely used in medicine (sulfamethoxazole, methyl sulfothorum, four waumets, nitro waumets, flurane), pesticide (insecticide, sterilization, end killing, weeding, virus prevention, etc.), chemical fertilizer (nitrogen fertilizer synergist), silk industry, agriculture, metal beneficiation photographic materials, etc.
This product is a new kind of highly effective reducing agent. An environmental-friendly product which can be used in replace of sodium hydrosulfite.
Cleaning Clear is sulfinic acid derivatives, an environmental-friendly product which can be used in replace of sodium hydrosulfite. Reduction ability and stability are higher than sodium hydrosulfite. Mainly used for reduction clearing after polyester disperse dyeing, dyeing pool, waste liquid cylinder’s cleaning and stripping, bad dye surface stripping, pulp bleaching and etc..
FAS is an excellent pulp and paper bleaching agent which is suited to use in both reduction bleaching and waste paper deinking. It is stable in air and can be used in conventional equipment. Thanks to its high reducibility and good stability, FAS is particularly suited to high temperature continuous bleaching, and is an environment friendly product which does not increase the waste water pollution load, conforming to environmental protection standards.
Sodium percarbonate tablets are a new and highly efficient oxygenation agent, and can sink to the bottom of pools, dissolving rapidly to generate oxygen in large quantities while inhibiting the growth of harmful bacteria. Sodium percarbonate is widely used to improve the water quality in waters for raising fish, crab and shrimps. It promotes adsorption and degradation of the organic matter in water to remove ammonia, nitrogen, hydrogen sulfide, and algal toxins.
Reducing Clear is mainly used in reductive cleaning of polyester, acrylic and other synthetic fiber and its blended fabric under weak alkaline environment. The effect is better than the traditional alkaline reduction. And the dosage is less.
Cotton Bleaching Agent is pretreatment auxiliaries with multi-functions. The product is composite of oxide agents, alkaline, alkaline agent, chelating dispersant, oxidation stabilizer, surfactant and etc. Apply to cotton, hemp, bamboo fiber and its blended product step scouring bleaching, knitted fabric desizing, scouring, bleaching one-step processing and cold pad-batch process.
Chemical industry for the production of sodium perborate, sodium percarbonate, peracetic acid, sodium chlorite, thiourea peroxide and other raw materials, tartaric acid, vitamins and other oxidants. The pharmaceutical industry is used as a disinfectant, disinfectant, and oxidant for the production of Formica biocides and 40l antibacterial agents. The printing and dyeing industry is used as a bleaching agent for cotton fabrics and a color agent for vat dyes after dyeing. Used to remove iron and other heavy metals in the production of metal salts or other compounds. It is also used in electroplating solution to remove inorganic impurities and improve the quality of plated parts. Also used for wool, raw silk, fur, feathers, ivory, bristles, pulp, fat and other bleaching. High concentrations of hydrogen peroxide can be used as rocket power fuel.
Ester Alcohol is premier coalescent for latex paints, especially performs well in all kinds of (meth) acrylic acid ester, styrene, vinyl acetate as raw materials and synthesis of various latex agent and other water-based paint system.
This product is used in PVC plastic solvent, can reduce the viscosity of the solution, while increasing the stability of the solution viscosity. Easy to mix with PVC resin, meanwhile to save time before the injection, extrusion, because of viscosity reduction in PVC solution, not easy to mix air bubbles, to maintain the finished product appearance and smooth.
Efficient film-forming additives for water-based coatings. Low toxicity and biodegradability. Mainly used for water-based steel structure coatings and other water-based industrial paint film-forming additives.
