Polycarboxylate superplasticizer is a kind of high performance water reducing agent, and it is also a cement dispersant in cement concrete application. Widely used in highways, bridges, dams, tunnels, high-rise buildings and other projects. The product is green and environmentally friendly, not flammable and explosive. It can be safely transported by train and car.

sodium lignosulfonate is a kind of organic matter, chemical formula is C20H24Na2O10S2, lignin is the content of nature after cellulose and chitin natural polymer, one of its most widely used is through the sulfonation modification into lignosulfonate, including sodium lignosulfonate (sodium ligninsulfonate). Sodium lignosulfonate can be used as an admixture for polymers and concrete, which has the advantages of low cost and environmental friendliness.

calcium lignosulfonate is a multi-component polymer anionic surfactant, the appearance of light yellow to dark brown powder, slightly aromatic odor, molecular weight is generally between 800~10000, with strong dispersion, adhesion, chelating. Waste cooking liquor, usually from acid pulping (or sulphite pulping), is spray dried. May contain up to 30% reducing sugar. Soluble in water, but insoluble in any common organic solvent. The pH value of 1% aqueous solution is about 4~6.

industrial sugar refers to raw sugar.

Industrial sugar implements GB 15108-2006 Raw Sugar.

Raw sugar contains a certain amount of impurities, the color is deeper than white sugar, contains relatively more water and molasses, and the microbial content is also higher than white sugar. Raw sugar can only be used for industrial production (mainly used to produce white sugar or soft sugar), can not be directly eaten, can not be directly added to food as raw materials.

d-sodium gluconate, English name is gluconic acid, sodium salt, Chinese also known as sodium gluconate, CAS number 527-07-1, molecular formula c20h25nao10, white crystalline particles or powder, soluble in water, slightly soluble in alcohol, insoluble in ether. Used for food additives, electroplating complexing agent, water quality stabilizer, color leveling agent in printing and dyeing industry, steel surface treatment agent, etc.
