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 ukukhulisa ukunamathela kwayo, ukusebenza kahle, ukunciphisa ukuhamba, ukuthuthukisa i-viscosity kanye nokuncipha, kanye nokugcina amanzi, ukunciphisa ukulahlekelwa kwamanzi endaweni ekhonkolo, ukuthuthukisa amandla, ukuvimbela imifantu kanye nesimo sezulu sikasawoti oncibilikayo emanzini, njll. Isetshenziswa kakhulu ku-plaster osekelwe kusimende, udaka lwegypsum, imikhiqizo yegypsum, udaka lwamatshe, i-sheet caulking, i-caulking agent, i-adhesive tile, i-self-leveling material floor, njll. Ingasetshenziswa njenge-ejenti eyenza ifilimu, i-thickener, i-emulsifier kanye i-stabilizer embotsheni ye-emulsion kanye ne-resin encibilikayo emanzini, inika ifilimu ukumelana okuhle nokuhuzuka, ukufana nokunamathela, kanye nokwenza ngcono ukungezwani kwendawo, ukuzinza kuma-asidi nezisekelo kanye nokuhambisana nemibala yensimbi. 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 lejeli 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 ngenhla 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.
