I-Gypsum Joint Compound, eyaziwa nangokuthi udaka lwe-drywall noma i-complic ehlanganyelwe nje, ingabe impahla yokwakha esetshenziswa ekwakhiweni nasekulungisweni kwe-drywall. Ihlanganiswe ngokuyinhloko i-gypsum powder, amaminerali athambile we-sulfate ahlanganiswa namanzi ukwakha unamathisela. Lo mjovo usetshenzisiwe kuma-seams, amakhona, nezikhala phakathi kwamaphaneli e-drywall ukudala indawo ebushelelezi, engenamthungo.
I-Hydroxypropylm methylcellulose (HPMC) yi-ether ye-cellulose evame ukungezwa ezintweni ezihlangene ezihlangene ngezizathu ezahlukahlukene. I-HPMC isuselwa ku-cellulose, i-polymer yemvelo etholakala ezindongeni zeseli zezitshalo. Nazi ezinye zezinto ezibalulekile zokusebenzisa i-HPMC e-Plaster Right Compact:
Ukugcinwa kwamanzi: I-HPMC yaziwa ngezakhiwo zayo ezinhle kakhulu zokugcina amanzi. Uma ungezwe ku-Plaster Right Compound, kuyasiza ukuvikela leyo ngxube ukuthi ikhishwe ngokushesha okukhulu. Isikhathi sokusebenza esandisiwe senza kube lula ukufaka isicelo futhi siqede impahla ehlangene.
Ukusebenza okwenziwe ngcono: Ukungezwa kwe-HPMC kuthuthukisa ukuqina kwe-compaction ehlanganisiwe. Inikeza ukuvumelana okubushelelezi, okwenza kube lula ukufaka isicelo futhi kusebenze ezindaweni ezi-drywall. Lokhu kubaluleke kakhulu ekufezeni imiphumela ebukeka kahle.
I-Adhesion: I-HPMC isiza ukuhambisana okuhlanganisiwe okuhlanganisiwe endaweni e-drywall. Kuyasiza ukuhlanganisa kuthambekele ngokuqinile kuma-seams namalunga, kuqinisekisa isibopho esiqinile nesihlala isikhathi eside uma owomile.
Yehlisa i-shrinkage: izinto ezihlangene ze-gypsum zivame ukuncipha njengoba zomile. Ukungezwa kwe-HPMC kusiza ukunciphisa i-shrinkage futhi kunciphise amathuba okuqhekeka avela endaweni eqediwe. Lokhu kubalulekile ukuthola imiphumela ephelele nehlala isikhathi eside.
Umenzeli wokufaka umoya: I-HPMC nayo isebenza njenge-ejenti yokufaka umoya. Lokhu kusho ukuthi kusiza ukufaka ama-bubble ka-microscopic emotweni emfuleni, ethuthukisa ukusebenza kwawo jikelele nokuqina.
Ukulawulwa Okuhlanganayo: I-HPMC ihlinzeka ngokulawula okukhulu ngokuvumelana kwe-compain ehlanganisiwe. Lokhu kusiza ukufeza ukuthungwa okufiselekayo nobukhulu ngesikhathi sohlelo lokusebenza.
Kubalulekile ukuqaphela ukuthi ukwakhiwa okuthile kwezinto ezihlangene ze-gypsum zingahlukahluka kumenzi nomenzi, futhi amamaki ahlukene we-HPMC angasetshenziswa ngokuya ngezakhiwo ozifunayo zomkhiqizo wokugcina. Ngokwengeziwe, ezinye izengezo ezifana nezikhukhunambisa, ama-beinders kanye nabathengi bangabangelwa ekwakhekeni ukuze bathuthukise ukusebenza.
I-Hydroxypropylm methylcellulose (HPMC) I-Cellulose ether idlala indima ebalulekile ekwenzeni ngcono ukusebenza, ukunamathela kanye nokusebenza okuphelele kwe-gypsum Joint Compands esetshenziswe ekwakhiweni nasekulungiseni. Izakhiwo zayo eziguquguqukayo zisiza ukufeza ukuqeda okubushelelezi futhi okuqinile ezindaweni ezi-drywall.
