Calcium lignosulfonate Calcium lignosulfonate лигносулонатовкалоо.
I. Product introduction:
Calcium lignosulfonate (hereinafter referred to as lignosulfonate) is a multi-component polymer anionic surfactant, which is brownish yellow powder with a slight aromatic smell. Its molecular weight is generally between 800 ~ 10000, and it has strong dispersibility, cohesiveness and chelation. At present, our company's series products of calcium lignosulfonate MG- 1, -2 and -3 have been widely used as cement water reducing agent, pesticide suspending agent, ceramic body reinforcing agent, coal water slurry dispersing agent, leather tanning agent, refractory binder, carbon black granulating agent and so on. , used in various industries, well received by users.
Main technical indicators (mg): brownish yellow powder.
Lignin content ≥ 50 ~ 65%
Water insoluble matter ≤ 0.5 ~ 1.5%
PH value 4.5-7
Moisture ≤4-7%
7- 13% reducing agent
Third, the main performance:
1, used as concrete water reducer: adding 0.25 ~ 0.3% cement can reduce water consumption by more than 10 ~ 14, improve concrete workability and improve engineering quality. Used in summer, it can inhibit slump loss, and is generally used in conjunction with superplasticizer.
2. Used as mineral binder: In smelting industry, calcium lignosulfonate is mixed with mineral powder to make mineral powder balls, which are put into kiln after drying, which can greatly improve the smelting recovery rate.
3. Refractory materials: When making refractory bricks and tiles, using calcium lignosulfonate as dispersant and binder can significantly improve the workability, and has good effects of reducing water, strengthening and preventing cracks.
4. Ceramics: When calcium lignosulfonate is used in ceramic products, it can reduce the carbon content, increase the green strength, reduce the amount of plastic clay, improve the fluidity of slurry, increase the yield by 70-90%, and reduce the sintering speed from 70 minutes to 40 minutes.
5. As a feed binder, it can improve the feeding preference of livestock and poultry, with good particle strength, reduce the dosage of micropowder in feed, reduce the powder return rate and reduce the cost. Die loss is reduced, productivity is increased by 10-20%, and the allowable dosage of feed in the United States and Canada is 4.0%.
6. Others: Calcium lignosulfonate can also be used for refining additives, casting, processing pesticide wettable powder, briquetting, mining, mineral processing agent for mining, road, soil and dust control, leather tanning filler, carbon black granulation, etc.
Four, packaging, storage and transportation:
1. packing: double packaging, polypropylene woven bag lined with plastic film, 25 kg/bag.
2. Storage: Store in a dry and ventilated place, and pay attention to moisture protection. Long-term storage does not deteriorate, and if it is caked, crushed or dissolved, it will not affect the use effect.
3. Transportation: This product is non-toxic, non-flammable and explosive. It can be transported by car or train.
