I-Gypsum joint compound, eyaziwa nangokuthi i-drywall mud noma inhlanganisela ehlangene nje, iyimpahla yokwakha esetshenziswa ekwakhiweni nasekulungiseni i-drywall. Ikakhulukazi yakhiwe nge-gypsum powder, i-soft sulfate mineral exutshwa namanzi ukuze yakhe unamathisele. Lokhu kunamathisela bese kusetshenziswa emithungo, emakhoneni, nasezikhaleni phakathi kwamaphaneli e-drywall ukuze kwakheke indawo ebushelelezi, engenamthungo.
I-Hydroxypropyl methylcellulose (HPMC) iyi-ether ye-cellulose evame ukungezwa ezintweni ezihlangene ze-plaster ngenxa yezizathu ezihlukahlukene. I-HPMC isuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. Nazi ezinye izici ezibalulekile zokusebenzisa i-HPMC kunhlanganisela ye-plaster joint:
Ukugcinwa Kwamanzi: I-HPMC yaziwa ngezakhiwo zayo ezinhle kakhulu zokugcina amanzi. Uma ihlanganiswa nenhlanganisela ye-plaster, isiza ukuvimbela ingxube ukuthi yome ngokushesha. Isikhathi sokusebenza esinwetshiwe senza kube lula ukufaka nokuqeda izinto ezihlangene.
Ukucutshungulwa okuthuthukisiwe: Ukwengezwa kwe-HPMC kuthuthukisa ukucutshungulwa kwenhlanganisela ehlangene. Ihlinzeka ngokungaguquguquki okushelelayo, okwenza kube lula ukukufaka nokufaka endaweni eyomile. Lokhu kubaluleke kakhulu ekuzuzeni imiphumela ebukeka iwuchwepheshe.
Ukunamathela: I-HPMC isiza inhlanganisela ehlangene ibambelele endaweni eyomile. Isiza i-compound ibambelele ngokuqinile kuma-seams namalunga, iqinisekisa isibopho esiqinile nesihlala isikhathi eside uma into yomile.
Yehlisa ukushwabana: Izinto ezihlangene zeGypsum zivame ukuncipha njengoba zoma. Ukwengezwa kwe-HPMC kusiza ukunciphisa ukuncipha futhi kunciphise amathuba okuqhekeka okuvela endaweni eqediwe. Lokhu kubalulekile ukuze uthole imiphumela ephelele futhi ehlala isikhathi eside.
I-ejenti Yokufaka Umoya: I-HPMC futhi isebenza njenge-ejenti yokungenisa umoya. Lokhu kusho ukuthi kusiza ukufaka amabhamuza omoya amancane kokubalulekile komthungo, kuthuthukise ukusebenza kwawo kukonke nokuqina.
Ukulawula Ukuvumelana: I-HPMC inikeza ukulawula okukhulu phezu kokuvumelana kwenhlanganisela ehlangene. Lokhu kusiza ukufeza ukuthungwa nokuqina okufunayo ngesikhathi sokufaka isicelo.
Kubalulekile ukuqaphela ukuthi ukwakheka okukhethekile kwezinto ezihlangene ze-gypsum kungase kuhluke kumkhiqizi kuya kumkhiqizi, futhi amabanga ahlukene e-HPMC angasetshenziswa kuye ngezici ezifunwayo zomkhiqizo wokugcina. Ukwengeza, ezinye izithasiselo ezinjengama-thickeners, ama-binder nama-retarders zingafakwa ekwakhiweni ukuze kuthuthukiswe ukusebenza.
IHydroxypropyl methylcellulose (HPMC) cellulose ether idlala indima ebalulekile ekuthuthukiseni ukusebenza, ukunamathela kanye nokusebenza kukonke kwezinhlanganisela ze-gypsum ezisetshenziswa ekwakhiweni nasekulungiseni i-drywall. Izakhiwo zayo eziguquguqukayo zisiza ukufeza isiphetho esibushelelezi nesihlala isikhathi eside ezindaweni ezomile.
