I-HPMC, noma i-Hydroxypropyl Methyl Cellulose, iyimpahla yokwakha eguquguqukayo futhi ebaluleke kakhulu ekhule ngokuduma eminyakeni yamuva nje.Njengento ephuma ku-cellulose, i-HPMC inezinhlelo zokusebenza ezisukela kwezimonyo kuya ezintweni ezinamathelayo, futhi okuphawuleka kakhulu, isithole indlela eya embonini yezokwakha njenge-thickener, adhesive, protective colloid, emulsifier and stabilizer.
I-HPMC yebanga lokwakha iyikhwalithi ephezulu, i-polymer encibilika emanzini esetshenziswa emikhiqizweni eyahlukene kasimende ehlanganisa izinto zokunamathisela zamathayela, amadaka, amaplasta, ama-grouts, kanye nezinhlelo zokuvala nokuvala zangaphandle (EIFS).Izakhiwo zayo eziguquguqukayo ziyenza ibe yisixazululo esiphelele sakho kokubili imiklamo yokwakha emisha neyokulungisa kabusha, njengoba ithuthukisa izakhiwo zokuhlanganisa nokuhlanganisa zezinto ezihlukahlukene.
Enye yezinzuzo eziyinhloko ze-HPMC yizindawo zayo ezinhle kakhulu zokugcina amanzi.Lokhu kusho ukuthi kungasiza ukunciphisa inani lamanzi adingekayo emikhiqizweni eyenziwe usimende ngaphandle kokudela izakhiwo noma ukusebenza kwengxube.Ngokugcina umswakama, kuvimbela ingxube ekumisweni, kusize ukuthuthukisa ukunamathela namandla omkhiqizo wokugcina.
Ngaphezu kwalokho, i-HPMC isebenza njenge-colloid evikelayo, esiza ukunciphisa ingozi yokuhlukaniswa, ukuqhekeka kanye nokuncipha kwezinto zikasimende.Lokhu kuyenza ibe isithasiselo esifanelekile semikhiqizo evezwa izimo zezulu ezinzima noma edinga ukumelana nengcindezi ephezulu.
Ngaphezu kwalezi zakhiwo ezithuthukisa ukusebenza, i-HPMC yaziwa kabanzi njengento esimeme kakhulu.Yenziwe ngezinsiza ezivuselelekayo, iyabola futhi ayinabo ubuthi, okuyenza ibe yinketho efanelekile kubakhi abaqaphela imvelo nezinkampani zokwakha.
Njengobufakazi bokuhlukahluka kwayo, i-HPMC iphinde isetshenziswe ekukhiqizeni imikhiqizo esekelwe ku-gypsum efana ne-stucco nezinhlanganisela ezihlangene.Kulokhu, i-HPMC isiza ukuthuthukisa ukusebenza nokuvumelana kwengxube, kuyilapho ikhulisa amandla esibopho phakathi kwe-stucco ne-substrate.
I-HPMC yebanga lezakhiwo itholakala ngezinhlobonhlobo zama-viscosity nosayizi bezinhlayiyana, okuvumela okokusebenza ukuthi kuhambisane nezidingo ezithile zomkhiqizo.Lokhu kuyenza ibe into evumelana nezimo kakhulu engasetshenziswa ezinhlotsheni zezicelo nasezindaweni ezizungezile.
Sengiphetha, i-HPMC iyinto ebalulekile embonini yezokwakha futhi izici zayo ezinhle ziningi.Ngokugcina amanzi kahle kakhulu, i-colloid evikelayo kanye nezindawo zokusimama, iyisengezo esiguquguqukayo nesibalulekile kunoma yimuphi umkhiqizo wokwakha.Ithuthukisa ukusebenza, inciphisa imfucuza futhi ilungele abakhi abaqaphela imvelo nezinkampani zokwakha.Ukusetshenziswa kwe-HPMC kukhanyisa ikusasa lemboni yezokwakha.
