Sodium Lignosulfonate

Sodium Lignosulfonate concrete water reducer are mainly for concrete mixture as water-reducing additive.

Sodium Ligninsulfonate

A spray dried fermented sodium lignosulphonate derived spruce wood sulphite liquor.It's a kind of natural anionic surface active agent processed with sulfurous acid pulping waste through advanced production technology. This product is mainly used in all kinds of concrete placing in site, preformed concrete, reinforced concrete and prestressed concrete, especially applicable for commercial concrete, anti-freezing concrete, waterproof concrete, bulk concrete, pumping concrete and so on. It is widely used in various concrete projects such as buildings, dams, culverts and expressways, etc, with high economic benefit. This product is also widely used in pesticide emulsifier, cradling dispersant, pre-tanning agent, ceramics or refractories plasticizer, oil well or water dam grouting gelling agent, etc.

Properties:

1 used as water reducing agent of concrete   In the field of concrete additives, the sodium lignsulphonate series products can be applied as common water reducing admixture and built material of series multi-function high-performance water reducing admixture. The products can be directly adopted as additive in the concrete. Moreover, they also can be compounded with such high-performance water reducing admixtures as naphthalene series and melamine series etc. And they are also ideal materials for series retarding agents and pumping agents etc.

2 additive of coal water slurry In the field of water-coal paste, the sodium lignosulphonate series products can be adopted as the main compound materials.

3 reinforcing agent of refractory material and ceramics The sodium lignosulphonate series products can be used as embryo reinforcing agents in the fields of pottery and porcelain and refractory materials. They can increase the fluidity of the slurry and thus to improve the strength of the embryo.

4 filler and dispersant of dye and pesticide In agriculture, the sodium lignosulphonate series products can be applied as the dispersant agents of pesticides and pelleting adhesives of fertizers and feedstuffs.

5 The sodium lignosulphonate series products can be adopted as the adhesives in the briquetting procedure in the vertical retort zinc smelters.

Packing, storage & transportation:

1, Packing: 25kg in PP woven bag lined with plastic film. 2 Storage: Kept in dry and ventilating place, prevent from rain and moisture when storage; if agglomerated, please crush and make it into solution, and its effect will be the same. 3 Transportation:non-toxic, harmless, non-inflammable and non-explosive chemicals, it can be transported in truck and train.
