Ukusetshenziswa kwe-hydroxypropyl methylcellulose (HPMC) njenge-thickener kuma-putty mortars kube nomthelela omkhulu embonini yezokwakha.I-HPMC iyi-polymer encibilika emanzini enezinzuzo eziningi ekuthuthukiseni ukusebenza kwe-putty powder.Lesi sihloko sizochaza umphumela wokujiya we-HPMC kuma-putty mortars nokuthi kungani ibaluleke kakhulu embonini yezokwakha.
I-putty powder iyimpahla yokwakha ethandwayo esetshenziselwa ukushelela indawo efana nezindonga nophahla.Yenziwa ngokuxuba i-gypsum powder, i-talc nezinye izigcwalisi ngamanzi.I-putty powder yaziwa nangokuthi inhlanganisela ehlangene, i-plaster noma udaka.Ukufaka i-putty powder ngaphambi kokudweba noma ukwenza iphepha lodonga kubalulekile njengoba kunikeza indawo ebushelelezi ukuze isiphetho sokugcina sinamathele kuso.
Inselele enkulu nge-putty powder ukuhambisana kwayo.Kuvame ukuba mncane futhi kube nzima ukukusebenzisa nokulawula.Yilapho i-HPMC ingena khona. Uma yengezwe kuma-putty powders, i-HPMC isebenza njengento ejiya, ithuthukisa ukuthungwa nokuvumelana kwengxube.Ithuthukisa ukunamathela nokubumbana kodaka, okwenza kube lula ukusebenzisa nokulawula, ukunciphisa udoti wezinto ezibonakalayo.
I-HPMC inezinto ezinhle kakhulu zokujiya futhi ingamunca inani elikhulu lamanzi ukuze yakhe into efana nejeli.Uhlobo nokugxila kwe-HPMC esetshenzisiwe kunganquma izinga lokujiya.I-HPMC nayo incike ku-pH, okusho ukuthi umphumela wayo wokujiya uyahlukahluka kuye nge-acidity noma i-alkalinity yengxube.
Ngaphezu kokuqina, i-HPMC ineminye imisebenzi ebalulekile kuma-putty powders.Inciphisa okuqukethwe kwamanzi ekuxubeni futhi kwandisa amandla omkhiqizo ophelile.Iphinde isebenze njenge-surfactant, inciphisa ukungezwani okungaphezulu kwe-putty powder.Ngokulandelayo, lokhu kubangela ukumbozwa okungcono nokuphelele kwendawo ephathwayo.
Enye inzuzo ebalulekile yokusebenzisa i-HPMC kuma-putty powders yikhono layo lokuthuthukisa ukusebenza kwengxube.I-HPMC inezici ezinhle kakhulu ze-rheological, okusho ukuthi ingalawula ukuthi ingxube iziphatha kanjani lapho isetshenziswa.Iqinisekisa ukuthi ingxube ye-putty igeleza kahle, isakazeka kalula, futhi ayinciphisi noma ayiconsi ngesikhathi sokufakwa.
Kukhona futhi izinzuzo zemvelo zokusebenzisa i-HPMC kuma-putty powders.I-HPMC iyimpahla evuselelekayo nebolayo, okusho ukuthi iphuka ngokwemvelo ngemva kokusetshenziswa.Lokhu kuhluke kakhulu kwezinye izinto zokwenziwa ezingashiya izinsalela eziyingozi futhi zingcolise imvelo.
Ama-putty powders enziwe nge-HPMC ahambisana nokuthungwa nokujiya, okuholela endaweni ebukeka kangcono.Inikeza indawo ebushelelezi, elinganayo, enciphisa isidingo sokwengeza isihlabathi nokugcwalisa.Lokhu kusho ukonga izindleko nokuqedwa ngokushesha kwamaphrojekthi wokwakha.
Kafushane, i-HPMC iyisithako esiyinhloko kuma-putty powders ukuze kuzuzwe ukuvumelana okufunayo, amandla nokusebenza.Ukuqina kwayo kanye nezakhiwo ze-rheological zenza kube yinto enhle kakhulu embonini yezokwakha, ukuthuthukisa izinga lomsebenzi nokusebenza kahle.Njengempahla evuselelekayo nebolayo, i-HPMC nayo inezinzuzo zemvelo.Ukwengezwa kwayo kuqinisekisa ukushelela, ngisho nokuqeda okungaphezulu okubalulekile kunoma iyiphi iphrojekthi yokwakha.
