Jan 09, 2018

There are many types of retarders, commonly used are: lignin sulfonate and its derivatives, low molecular weight cellulose and its derivatives, hydroxycarboxylic acid (salt), organic phosphonic acid (salt), boric acid And so on. At home and abroad for the existing retarder defects have been continuously improved, but also the development of a number of retarders.

Specific examples of substances that can be used as retarders include dextrin, various types of starch, casein, and certain protein-containing substances; as well as sucrose, glucose, calcium lignosulfonate or sodium salt, carboxymethylcellulose Sodium carboxymethyl cellulose (CHC), and mixtures thereof; additionally tartaric acid, potassium tartrate, calcium tartrate, calcium sulfate dihydrate, calcium sulfite, ferrous sulfate, boric acid, mixtures of boric acid and tartaric acid, A mixture of tartaric acid and sodium bicarbonate, sodium hexametaphosphate, phosphoric acid, bicine, trisodium phosphate, tetrasodium phosphate, disodium hydrogen phosphate, sodium pyrophosphate, alkyl phosphates, disodium ethylenediaminetetraacetate Such as humic acid.
