one.CMC for Oil Drilling: It can boost viscosity and reduce h2o decline in drilling fluid, cementing fluid and fracturing fluid. It also plaEPTthe role of defending the wall of effectively, using drilling trifles, guarding drilling little bit, preventing mEPTloss and growing drilling fee.
*Usage: include to mEPTdirectly or glue solution preparation.
*Addition: .one-.three% in fresh drinking water mud .five-.8% in salt water mud.
two.CMC Ceramic Quality: It really is used for ceramic embryo, glazing pulp and coloured glaze in ceramic industry.
*Addition:.03%-.2% utilized in ceramic embryo .05-.two% employed in glazing pulp one.4-4.% employed in coloured glaze.
3.CMC Paper Quality: It’s employed in producing pulp so as to improve the retention price and increase humidity and strength when utilized in surface sizing, CMC can improve interior adhesion, reduce printing dust and increase printing high quality as molding reagent. In paper coating, CMC also will help the dispersion and fluidity of paint, improves appearance of paper and smoothness, upgrades optical performance and printing adaptability.
4.CMC Development Grade: Employed in construction to improve h2o retention and energy.
five.CMC for other EPT:As coagXiHu (West Lake) Dis.Hu (West Lake) Dis.t, drinking water reXiHu (West Lake) Dis.Hu (West Lake) Dis., thickener and binder, it’s also used in paint, carpet gum, mosquito coil incense, tobacco, electric welding, textile, battery, printing and other individuals.
