- sodium lignosulphonate
Sodium lignosulphonate is light yellow (brown) free flowing powder, as the water reducing admixtures taking on the feature of small dosage, high reducing rate, low gas content, good workability and convenience.
Sodium lignosulphonate is modified nature lignin product, taking on powder, having a little fragrance, no poisonous, no harmful. Have a good moisture absorption ability, water solubility and high chemical stability, fair absorbability, dispersion, and
humidification and Lubrication.
Sodium lignosulphonate can be widely used in construction, ceramics, mineral powder, chemical industry, metallurgical industry, petroleum industry, fire-retardant materials, and CWS dispersion agent.
- calcium lignosulphonate
Calcium lignosulfonate is an anionic surfactant, as the main component of sulfite pulp is processed by advanced production technology , light brown powder and easily soluble in water. It can work well with other chemicals
Calcium lignosulphonate is suitable for using as admixture for concrete construction, petroleum drilling, asphalt emulsification, tanning leather, dispersant of chemical and pesticide, additive of slurry mixture of water and coal , adhesive of feedstuffs processing.
- sodium gluconate
Sodium gluconate is the sodium salt of gluconic acid..It is white or pale yellow crystalline granules or powder; quite easily soluble in water, slightly soluble in alcohol, insoluble in ether
Sodium gluconate is mainly used as a kind of retarding admixtures. Retarding admixtures (retarders) are known to delay hydration of cement without affecting the long-term mechanical properties. They are used in concrete to offset the effect of high temperatures, which decrease setting times, or to avoid complications when unavoidable delays between mixing and placing occur .
- sodium naphthalene sulfonate formaldehyde
Sodium naphthalene formaldehyde is high range water-reducing and an anion surface active agent based on polyalkyaryl- sulphonate.
Sodium Naphthalene Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. PNS also allows concrete to be produced with very low water/ cement ratios at low or normal slumps.
Sodium Naphthalene Formaldehyde is ideal for use in prestress, precast, bridge deck or any concrete where it is desired to keep the water/ cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidation.
- poly naphthalene sulfonate formaldehyde
Poly Naphthalene Sulfonate Formaldehyde is high range water-reducing and an anion surface active agent based on polyalkyaryl- sulphonate.
Poly naphthalene sulfonate is a high range concrete admixture of concrete cast-in-place, prefabricating, pump and curing. It has a good adaptability to various cements and PNS is no erodent to reinforcing bar and nonpoisonous and pollution-free. It has been applied to the highway, bridge, tunnel, water conservancy hydroelectric project, port, quay, skyscraper, power engineering, industrial civil building, prestressing force component and high range concrete etc.
Poly Naphthalene Sulfonate Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. PNS also allows concrete to be produced with very low water/ cement ratios at low or normal slumps.
- sodium ligno sulphonate
Sodium lignosulphonate is light yellow (brown) free flowing powder, as the water reducing admixtures taking on the feature of small dosage, high reducing rate, low gas content, good workability and convenience.
Concrete industry:
At the concrete manufacture and dry construction, it reduces the conception of components up to 10-15% remixing of the concrete mass reduces and its solidity rises, the speed of hardening slows down. Usage of lignosulphonates reduces humidity of raw mud if conserving its flow behaviour which rises the manufacture of stove and reduces specific flow volume to the burning of clinker, with the usage of intensifier on the base of lignosulphoantes the production of grinding units rises and there is an opportunity to change expansive and deficit chemical products.
Building materials production:
Sodium lignosulphoante can be used in producing plates because of its astringent, sticking and surface active propertities. Because this kind of production is very expensive, toxic, carbamide are used, mixture of modified lignosulphoante with loam can get combined binder. Meanwhile the toxication of the plates can be reduced up to 50%.. And in the producing of mineral-cotton plates, the products can become more firm and water-proof.
