calcium lignosulphonate concrete chemicals additives

Specification：

The mian ingredient of lignin calcium sulfate is sulfate is sulfate wood pulp waste. yests lignin calcium sulfate is a kind of power solid with the coffee color made by advanced production technology with good solubility.it is a kind of macromolecule electrolyte with 1000-100000 molecular weight .among the molecular weight 10000-40000 dispersing capability is especially effective the ordinary lignin sulonic salt has ramose and intersectant molecular structure.

Lignin calcium sulfate features strong dispersing ability ,viscosity and adhesion.as said above that the molecular weight of lignin calcium sulfate is different,so it has different degree of dispersing ability .it has the feature of water –solubility hydrophilic pectic with electric charge on the particle .it is a kind of salt  produced by the strong acid,so it can be conducted metal hydronium exchange actions .all kinds of active genes existing on theorganic structure of lignin sulfur acid enable the intrinsic polymeric actions of yield condensation actions with other compounds.

 Due to the above-mentioned characteristics of lignin calcium sulfate,it can be used as concrete water-reducing material ,thinner for cement pulp,sand reinforcement material,pesticide emulsion,mill run dispersant,leather pre-tanning material,grouting jello for oil well or dam and so on.at present yests calcium sulfate is widely used in such industries as building industry,water and electricity ,metallurgy ,pesticide .petroleum, mining and porcelain industries,etd.

Advantages：

Main performance parameters and economic effects of yeats lignin calcium sulfate water-reducing material.

1.       improving the concrete performance

2.       retrenching cement

3.       improving the concrete’s unassuming ability

4.       having the function of retarder

5.       reducing the early hydrate heat of cement

6.       gassy contents of the concrete will increase

7.       the water-seepage rate will reduce

8.       dry-shrinking performance

9.       increasing the close –grained degree of concrete and improving the antitransudatory capability of concrete

10.   non-chlorine salt is not rust harmful to the reinforcing bars

11.   non-alkaline active materials
