Impuphu ye-latex ephinde ihlakazeke isetshenziswa ekumbozweni okungangeni manzi kwe-JS okuyingxenye eyodwa, udaka lokubopha ibhodi le-polystyrene lokuvikela ukwakha, udaka lokuvikela ubuso oluguquguqukayo, udonga lokuvikela ukushisa kwezinhlayiya ze-polystyrene, ingcina yethayela, udaka oluzilinganisayo, udaka oluxubile okomile, i-putty, njll. Insimu yokuguqula izinto ze-gelling ezingaphili isetshenziswe kabanzi.
Ukwengeza i-latex powder ephinde ihlakazeke ku-putty powder kungandisa amandla ayo, kube nokunamathela okuqinile kanye nezakhiwo zemishini, futhi kusize ekuthuthukiseni ubulukhuni. Inokumelana okuhle kwamanzi, ukungena kwamanzi, kanye nokuqina okuhle kakhulu. I-alkaline, imelana nokuguguleka, futhi ingathuthukisa ukugcinwa kwamanzi, yandise isikhathi sokuvula, futhi ithuthukise ukuqina.
Uma i-latex powder ephinde ihlakazeke ivuselelwa ngokulinganayo ku-putty powder bese ixutshwa namanzi, ihlakazeka ibe yizinhlayiya ezincane ze-polymer; i-cement gel yenziwa kancane kancane ngokumanzisa kokuqala kwe-cement, futhi isigaba soketshezi sakhiwa yi-Ca(OH)2 enqubweni yokumanzisa. Igcwele, kuyilapho i-latex powder yakha izinhlayiya ze-polymer futhi ibeka phezu kobuso be-cement gel/ingxube yezinhlayiya ze-cement engamanzi; njengoba i-cement iqhubeka nokumanzisa, amanzi kuma-capillary ayancipha, futhi izinhlayiya ze-polymer zincishiswa kancane kancane kuma-capillary. Ingxube yezinhlayiya ze-cement ezinamathelayo/ezingamanzi kanye nobuso bokugcwalisa kwakha ungqimba olusondelene; ngaphansi kwesenzo sokumanzisa, ukumuncwa kwesendlalelo esiyisisekelo kanye nokuhwamuka kobuso, amanzi ancishiswa kakhulu, futhi ungqimba oluhlanganisiwe oluhlanganisiwe luhlangana lube yifilimu, olubopha umkhiqizo wokusabela kokumanzisa ku-Together bakha isakhiwo senethiwekhi esiphelele. Uhlelo oluhlanganisiwe olwakhiwe ngokumanzisa kwe-cement kanye nokwakheka kwefilimu ye-latex powder lungathuthukisa ukumelana okunamandla kokuqhekeka kwe-putty ngesenzo sokujoyina.
I-putty esetshenziswa njengengqimba yokushintshana phakathi kokufakwa kodonga lwangaphandle kanye nopende akufanele ibe namandla kunodaka lokuplasta, kungenjalo ukuqhekeka kuzokwenzeka kalula. Kuhlelo lonke lokufakwa kodonga, ukuguquguquka kwe-putty kufanele kube phezulu kunokwezinto eziyisisekelo. Ngale ndlela, i-putty ingazivumelanisa kangcono nokuguqulwa kwe-substrate futhi ivikele ukuguquguquka kwayo ngaphansi kwesenzo sezici zangaphandle zemvelo, inciphise ukugxila kokucindezeleka, futhi inciphise amathuba okuqhekeka nokuqhekeka kwengubo.
