Dark Brown Lignosulfonate Lignin Powder 50% Min Used In Smelting Casting Adhesives

Lignosulfonate Lignin mainly used in smelting, casting, adhesives.

Lignosulfonate, also known as lignin sulfonate, is a byproduct of sulfite papermaking wood pulp, which can be used as water reducing agent for concrete, refractory materials, ceramics and so on. It is prepared by precipitation, separation and drying with precipitating agent such as lime, calcium chloride and basic lead acetate.

Main applications:

Used in oil drilling mud, oil well fracturing, tertiary oil recovery to enhance oil recovery and other processes. It can be used in industrial water treatment and tannery industry. The application in electroplating industry makes the electroplating surface more bright. It can also be used as coal water slurry dispersant and concrete water reducing agent, gypsum board production additives, pesticide additives, printing and dyeing diffusion agent, rubber wear-resistant agent, etc. It can also be used as a raw material or intermediate for the production of dyes, vanillin and tanning agents, instead of 50% phenol and formaldehyde condensation into plastic products.

Usage:

Used as a water reducing agent for concrete: 0.2-0.3% of the weight of cement, which can reduce the water consumption by more than 10-15%, improve the workability of concrete and improve the quality of engineering. Used in summer, it can inhibit slump loss, and is generally used in combination with high efficiency water reducing agents.

Used as a flotation agent and smelting powder binder, smelting industry with lignosulfonate calcium mixed with mineral powder, made of mineral powder ball, dried into the kiln, can improve the smelting recovery.

Refractory materials: When manufacturing refractory bricks, the use of calcium lignosulfonate as a dispersant and binder can improve operational performance, and has good effects such as reducing water, strengthening and preventing cracking.

Ceramics: Used for ceramic products can reduce carbon content to increase green strength, reduce the amount of plastic clay, good mud flow, improve the yield of 70-90%, sintering speed reduced from 70 minutes to 40 minutes.

Other: Calcium lignosulfonate can also be used in refining additives, casting, coal water slurry dispersant, pesticide wettable powder processing, briquette pressing, road, soil, dust suppression, leather tanning filler, carbon black granulation, feed binder and other aspects.

Example of use: Sodium lignosulfonate is an anionic surfactant, brown-yellow powder. It is mainly used for the dispersion and filling of disperse dyes and VAT dyes. It has good dispersion, heat stability and high temperature dispersion, good grinding effect, light contamination to fibers, and small reducibility to azo dyes.

How to use:

1. Sodium lignosulfonate is mainly used for dispersing and reducing dyes, and can also be used as diluent and pigment dispersant for acid dyes.

2, as a high efficiency concrete water reducer, superior performance than calcium lignosulfonate, suitable for culverts, DAMS, reservoirs, airports and highways and other projects.

3, used for lead acid battery and alkaline battery cathode shrink agent, improve the low temperature rapid discharge capacity and service life of the battery; Used for electroplating can make the coating uniform, no tree pattern; Used in the fur industry as a tanning agent; As a scale remover on the boiler; Advanced flotation agent used in metallurgical mining.

4, used for coal water slurry dispersant, with other dispersants can effectively reduce the cost.

Storage: should pay attention to prevent moisture, rain, avoid caking, if there is caking, smashing or dissolving does not affect the use effect; This product is non-toxic and harmless, long-term storage does not deteriorate, is a non-flammable and explosive dangerous goods.
