I-HPMC kanye ne-HEMC emkhakheni wokwakha

I-HPMC ne-HEMC zinendima efanayo ezintweni zokwakha. Ingasetshenziswa njenge-dispersant, i-ejenti yokugcina amanzi, i-ejenti yokuqina kanye ne-binder, njll. Isetshenziswa kakhulu ku-cement mortar kanye nokubumba imikhiqizo ye-gypsum. Isetshenziswa ku-cement mortar ukwandisa ukunamathela kwayo, ukusebenza kahle, ukunciphisa ukugoba, ukuthuthukisa i-viscosity kanye nokuncipha, kanye nokugcina amanzi, ukunciphisa ukulahlekelwa amanzi ebusweni bekhonkrithi, ukuthuthukisa amandla, ukuvimbela imifantu kanye nokuguquka kosawoti oncibilika emanzini, njll. Isetshenziswa kabanzi ku-plaster esekelwe kusimende, i-gypsum plaster, imikhiqizo ye-gypsum, i-masonry mortar, i-sheet caulking, i-caulking agent, i-tile adhesive, izinto eziphansi ezizilinganisayo, njll. Ingasetshenziswa njenge-ejenti yokwakha ifilimu, i-thickener, i-emulsifier kanye ne-stabilizer ku-emulsion coatings kanye ne-resin coatings encibilika emanzini, inikeze ifilimu ukumelana okuhle kokuguguleka, ukufana kanye nokunamathela, kanye nokuthuthukisa ukucindezeleka kobuso, ukuzinza kuma-acid kanye nezisekelo kanye nokuhambisana nemibala yensimbi. Ngenxa yokuqina kwayo okuhle kokugcina i-viscosity, ifaneleka kakhulu njenge-dispersant ku-emulsified coatings. Ngamafuphi, nakuba inani elisesimisweni lincane, liwusizo kakhulu futhi lisetshenziswa kabanzi.

Izinga lokushisa lejeli le-cellulose ether linquma ukuzinza kwalo kokushisa ekusetshenzisweni. Izinga lokushisa lejeli le-HPMC livame ukusuka ku-60°C kuya ku-75°C, kuye ngohlobo, okuqukethwe yiqembu, izinqubo ezahlukene zokukhiqiza zabakhiqizi abahlukene, njll. Ngenxa yezici zeqembu le-HEMC, linokushisa okuphezulu kwejeli, ngokuvamile okungaphezu kuka-80°C. Ngakho-ke, ukuzinza kwalo ngaphansi kwezimo zokushisa okuphezulu kuphakeme kunokwe-HPMC. Empeleni, ngaphansi kwendawo yokwakha eshisa kakhulu ehlobo, ukugcinwa kwamanzi kwe-HEMC ku-wet mix mortar ene-viscosity efanayo kanye nomthamo kunenzuzo enkulu kune-HPMC.

I-cellulose ether eyinhloko embonini yokwakha yaseShayina isalokhu iyi-HPMC, njengoba inezinhlobo eziningi namanani aphansi, futhi ingakhethwa ngokukhululeka ngezindleko eziphelele. Ngokuthuthuka kwemakethe yokwakha yasekhaya, ikakhulukazi ukwanda kokwakhiwa ngomshini kanye nokuthuthukiswa kwezidingo zekhwalithi yokwakha, ukusetshenziswa kwe-HPMC emkhakheni wokwakha kuzoqhubeka nokukhula.
