I-Gypsum joint compound, eyaziwa nangokuthi udaka lwe-drywall noma i-joint compound nje, iyinto yokwakha esetshenziswa ekwakheni nasekulungiseni i-drywall. Yakhiwa ngokuyinhloko nge-gypsum powder, i-mineral sulfate ethambile exutshwa namanzi ukuze yakhe i-paste. Le paste ibe isisetshenziswa emithungweni, emakhoneni, nasezikhaleni phakathi kwamaphaneli e-drywall ukuze kudalwe indawo ebushelelezi nengenamthungo.
I-Hydroxypropyl methylcellulose (HPMC) iyi-cellulose ether evame ukungezwa ezintweni zokuhlanganiswa kwe-plaster ngezizathu ezahlukahlukene. I-HPMC itholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo. Nazi ezinye izici ezibalulekile zokusebenzisa i-HPMC ku-plaster joint compound:
Ukugcinwa Kwamanzi: I-HPMC yaziwa ngezakhiwo zayo ezinhle kakhulu zokugcina amanzi. Uma ifakwa enkomponini yokuhlanganiswa kweplasta, iyasiza ekuvimbeleni ingxube ukuthi ingomi ngokushesha okukhulu. Isikhathi eside sokusebenza senza kube lula ukufaka nokuqeda izinto zokuhlanganiswa.
Ukusebenziseka kalula: Ukwengezwa kwe-HPMC kuthuthukisa ukusebenziseka kalula kwenhlanganisela ehlangene. Kuhlinzeka ngokuhambisana okubushelelezi, okwenza kube lula ukufaka nokufaka ezindaweni ezilukiwe. Lokhu kubaluleke kakhulu ekufinyeleleni imiphumela ebukeka njengobungcweti.
Ukunamathela: I-HPMC isiza inhlanganisela ehlangene inamathele ebusweni be-drywall. Isiza inhlanganisela inamathele ngokuqinile emithungweni nasemajoyintini, iqinisekisa ukubopha okuqinile nokuhlala isikhathi eside uma impahla yomile.
Nciphisa ukushwabana: Izinto ezihlanganisiwe ze-Gypsum zivame ukushwabana njengoba zoma. Ukwengezwa kwe-HPMC kusiza ukunciphisa ukushwabana futhi kunciphise amathuba okubonakala kwemifantu ebusweni obuqediwe. Lokhu kubalulekile ukuze uthole imiphumela ephelele nehlala isikhathi eside.
I-Air Entraining Ejenti: I-HPMC isebenza futhi njenge-air entraining ejenti. Lokhu kusho ukuthi isiza ukufaka amabhamuza omoya amancane ezintweni zomthungo, ithuthukise ukusebenza kwayo kanye nokuqina kwayo.
Ukulawula Ukuvumelana: I-HPMC inikeza ukulawula okukhulu phezu kokuvumelana kwenhlanganisela ehlangene. Lokhu kwenza kube lula ukufeza ukuthungwa kanye nobukhulu obufunwayo ngesikhathi sokusetshenziswa.
Kubalulekile ukuqaphela ukuthi ukwakheka okuthile kwezinto zokuhlanganisa i-gypsum kungahluka kumkhiqizi ngamunye, futhi amazinga ahlukene e-HPMC angasetshenziswa kuye ngezakhiwo ezifiselekayo zomkhiqizo wokugcina. Ngaphezu kwalokho, ezinye izithasiselo ezifana nezithina, izihlanganisi kanye nezithina zingafakwa ekwakhiweni ukuze kuthuthukiswe ukusebenza.
I-Hydroxypropyl methylcellulose (HPMC) cellulose ether idlala indima ebalulekile ekuthuthukiseni ukusebenza kahle, ukunamathela kanye nokusebenza kahle kwamakhemikhali e-gypsum joint asetshenziswa ekwakhiweni nasekulungisweni kwe-drywall. Izakhiwo zayo eziguquguqukayo zisiza ekufezeni ukuphela okubushelelezi nokuqinile ezindaweni ze-drywall.
