one.CMC for Oil Drilling: It can boost viscosity and reduce drinking water reduction in drilling fluid, cementing fluid and fracturing fluid. It also plaEPTthe function of safeguarding the wall of properly, getting drilling trifles, guarding drilling little bit, preventing mEPTloss and escalating drilling fee.
*Use: include to mEPTdirectly or glue remedy planning.
*Addition: .one-.three% in new drinking water mud .five-.eight% in salt h2o mud.
2.CMC Ceramic Quality: It really is used for ceramic embryo, glazing pulp and coloured glaze in ceramic sector.
*Addition:.03%-.two% employed in ceramic embryo .05-.two% used in glazing pulp 1.4-four.% employed in coloured glaze.
three.CMC Paper Quality: It truly is utilised in producing pulp so as to enhance the retention price and boost humidity and strength when employed in area sizing, CMC can improve inside adhesion, lessen printing dust and boost printing quality as molding reagent. In paper coating, CMC also aids the dispersion and fluidity of paint, improves visual appeal of paper and smoothness, updates optical overall performance and printing adaptability.
four.CMC Construction Grade: Used in design to increase drinking water retention and energy.
5.CMC for other EPT:As coagXiHu (West Lake) Dis.Hu (West Lake) Dis.t, water reXiHu (West Lake) Dis.Hu (West Lake) Dis., thickener and binder, it is also utilized in paint, carpet gum, mosquito coil incense, tobacco, electrical welding, textile, battery, printing and others.
