I-HPMC kanye ne-HEMC emkhakheni wokwakha

I-HPMC kanye ne-HEMC banendima efanayo ezintweni zokwakha. Ingasetshenziswa njenge-dispersant, i-ejenti yokugcina amanzi, i-ejenti yokuqina kanye ne-binder, njll. Isetshenziselwa ikakhulukazi udaka lukasimende kanye nokubumba kwemikhiqizo ye-gypsum. Isetshenziselwa udaka lukasimende ukwandisa ukunamathela kwayo, ukusebenza kahle, ukunciphisa i-flocculation, ukuthuthukisa i-viscosity kanye nokuncipha, kanye nokugcina amanzi, ukunciphisa ukulahlekelwa kwamanzi endaweni ekhonkolo, ukuthuthukisa amandla, ukuvimbela ukuqhekeka kanye nesimo sezulu sikasawoti oncibilikayo emanzini, njll. Isetshenziswa kabanzi ku-plaster-based-samente, i-gypsum plaster, i-gypsum ishidi, imikhiqizo ye-gyulking morir, imikhiqizo ye-masonryking mortar i-adhesive, self-leveling floor material, njll. Ingasetshenziswa njenge-ejenti eyenza ifilimu, i-thickener, i-emulsifier kanye ne-stabilizer e-emulsion coatings kanye ne-resin encibilikayo emanzini, inikeze ifilimu ukumelana nokuhunywa okuhle, ukufana nokunamathela, nokuthuthukisa ukungezwani kwendawo, ukuzinza kuma-acids nezisekelo kanye nokuhambisana nensimbi yengulube. Ngenxa yokuzinza kwayo kwesitoreji esihle se-viscosity, ifaneleka ngokukhethekile njenge-dispersant emigqonyeni ye-emulsified. Ngamafuphi, nakuba inani elikuhlelo lincane, liwusizo kakhulu futhi lisetshenziswa kabanzi.

Izinga lokushisa lejeli le-cellulose ether linquma ukuzinza kwalo okushisayo ezinhlelweni zokusebenza. izinga lokushisa le-gel le-HPMC livame ukusuka ku-60 ° C kuya ku-75 ° C, kuye ngokuthi uhlobo, okuqukethwe kweqembu, izinqubo ezahlukene zokukhiqiza zabakhiqizi abahlukene, njll. Ngenxa yezici zeqembu le-HEMC, linokushisa kwe-gel eliphezulu, ngokuvamile ngaphezu kuka-80 ° C. Ngakho-ke, ukuzinza kwayo ngaphansi kwezimo eziphakeme zokushisa kungaphezu kwalokho kwe-HPMC. Empeleni, ngaphansi kwendawo yokwakha eshisa kakhulu ehlobo, ukugcinwa kwamanzi kwe-HEMC odakeni oluxubile olumanzi olune-viscosity efanayo kanye ne-dosing kunenzuzo enkulu kune-HPMC.

I-cellulose ether evamile embonini yezokwakha yase-China iseyi-HPMC, njengoba inezinhlobo eziningi nezintengo eziphansi, futhi ingakhethwa ngokukhululekile ngezindleko eziphelele. Ngokuthuthuka kwemakethe yezokwakha yasekhaya, ikakhulukazi ukwanda kokwakhiwa kwemishini kanye nokuthuthukiswa kwezidingo zekhwalithi yokwakha, ukusetshenziswa kwe-HPMC emkhakheni wokwakha kuzoqhubeka nokukhula.
