sodium carboxymethyl cellulose CMC
Product Description
1. Product introduction:
CMC is one kind of anion gathers the electrolyte, by the chloroacetic acid sodium and the alkali cellulose response system, divides Gao Zhan (HV-CMC), to stick (MV-CMC), to stick (LV-CMC) lowly and in the alkalinity sticks, the outward appearance is the white or the iron grey powder, non-toxic, dissolves in cold water or the hot water, the peroxide solution to stick the thick shape colloid.
2 . Performance use:
CMC mainly does in the drilling fluid increases sticks the fluid-loss agent, the carboxymethylcellulose sodium salt long member chain can with many clay particle adsorption, can increase the filter cake the cementation, can suppress the shale hydration inflation and the consolidated wall function. The carboxymethylcellulose sodium salt's peroxide solution has the fine nature and the chemical stability, is not easy to corrode the deterioration, to physiology safe harmless, has the suspension effect and the stable emulsification, the good cohesiveness and anti-salty ability, are good to the oil and the organic solvent stability, therefore, is widely used domains and so on petroleum, food, spinning and weaving, medicine, papermaking and everyday use chemical industry.
