I-HPMC ye-additive gypsum slurry

I-Hydroxypropyl Methylcellulose (HPMC) iyisengezo esisetshenziswa kabanzi embonini yezokwakha, ikakhulukazi ezintweni ezisekelwa yi-gypsum njengodaka kanye ne-gypsum slurry. Kuyinto eyi-cellulose elungisiwe ye-cellulose ether ethathwe kuma-polymers wemvelo, ngokuyinhloko iselula, ngokusebenzisa uchungechunge lokuphendula kwamakhemikhali.

Ezintweni ezisuselwa ku-gypsum, i-HPMC isebenza ngezinhloso eziningi:

Ukugcinwa kwamanzi: I-HPMC yakha ifilimu evikelayo ezungeze izinhlayiya ze-gypsum, ukuvimbela ukulahleka kwamanzi ngokuhwamuka. Lokhu kusiza ukugcina ukuvumelana nokusebenza kwe-gypsum slurry ngaphezulu kwezikhathi ezengeziwe, okuvumela uhlelo lokusebenza olulula nokuqedela okungcono.

Ukusebenza okwenziwe ngcono: Ngokulawula izinga le-hydration le-gypsum, i-HPMC ithuthukisa ukusebenziseka kwe-slurry, okwenza kube lula ukusakazeka, isikhunta kanye nesimo. Lokhu kubaluleke kakhulu kuzinhlelo zokusebenza ezifana nokuphamba nokubumba, lapho ukulawula okuqondile kokungaguquguquki kokwaziswa kubalulekile.

I-Adhesion ekhulayo: I-HPMC ithuthukisa ukunamathela kwe-gypsum kuma-substrates ahlukahlukene, njengezinkuni, insimbi, kanye noMasonry. Lokhu kubalulekile ekuqinisekiseni ubuhlobo obufanele nokuvimbela ukunxusa noma ukuqhekeka emikhiqizweni ye-gypsum eqediwe.

Yehlisa i-sagging kanye ne-shrinkage: Ukungezelelwa kwe-HPMC kungasiza ukunciphisa ukunciphisa ukugcoba nokushwabana ngezinto zokwelashwa nge-gypsum ngesikhathi sokwelapha, okuholela kumkhiqizo wokugcina onomfaniswano ofanayo.
Izakhiwo ezithuthukisiwe zemishini: I-HPMC ingathuthukisa izakhiwo zemishini zezinto zokwenziwa ze-gypsum, kufaka phakathi amandla, ukuqina, kanye nokumelana nomthelela. Lokhu kubenza balungele kakhulu izicelo ezahlukahlukene zokwakha, kusuka ekuqedeni okungaphakathi ezintweni ezihlelekile.

Ukuvumelana nezinye izengezo: I-HPMC iyahambisana nohlobo oluthile lwezinye izengezo ezisetshenziswayo ezakhiweni ze-gypsum, ezinjengabathengi be-retaarders, ama-accelerator, kanye nabathuthukisi bezindiza. Lokhu kuvumela ukuguquguquka okuthe xaxa ekuvumelaniseni izakhiwo ze-gypsum slurry kwizidingo ezithile zohlelo lokusebenza.

I-HPMC idlala indima ebalulekile njengezengezo ekwakhiweni kwe-gypsum slurry, okunikeza izinzuzo ezinjengokusebenza okuthuthukile, ukugcinwa kwamanzi, nokunamathela, kanye nezakhiwo zemishini. Ukusetshenziswa kwayo okusakazekile embonini yezokwakha kugcizelela ukusebenza kwayo ekuthuthukiseni ukusebenza nokuguquguquka kwezinto zokwakha ezisekelwe e-gypsum.
