Umphumela wokwengeza i-Redispersible polymer powder ku-putty powder

Impushana ye-latex edispersible isetshenziswa engxenyeni eyodwa ye-JS engangeni manzi, i-polystyrene board bonding mortar ukuze kuhlanganiswe isakhiwo, udaka lokuvikela indawo eguquguqukayo, i-polystyrene particle thermal insulation coating, ingcina yethayela, udaka oluzilinganisa, udaka oluxutshwe owomile, i-putty, njll. insimu yokuguqula izinto ze-inorganic gelling isetshenziswe kabanzi.

 

Ukwengeza i-latex powder ehlakazeka kabusha ku-putty powder kungakhuphula amandla ayo, kube nokunamathela okuqinile kanye nezakhiwo zemishini, futhi kusize ukuthuthukisa ubulukhuni. Inokumelana kahle namanzi, ukungena kwamanzi, nokuqina okuhle kakhulu. I-alkaline, ayigugi, futhi ingathuthukisa ukugcinwa kwamanzi, ikhulise isikhathi esivulekile, futhi ithuthukise ukuqina.

 

Lapho i-latex powder ehlakazeka kabusha inyakaziswa ngokulinganayo ku-putty powder futhi ixutshwe namanzi, ihlakazeka ibe yizinhlayiya ze-polymer ezinhle; Ijeli likasimende lakhiwa kancane kancane ngokusebenzisa i-hydration yokuqala kasimende, futhi isigaba se-liquid sakhiwe yi-Ca (OH) 2 ohlelweni lwe-hydration. Igcwele, kuyilapho i-latex powder yakha izinhlayiya ze-polymer kanye ne-deposit ebusweni bejeli ye-cement / ingxube yezinhlayiya zikasimende ezingenamanzi; njengoba usimende uqhubeka u-hydrated, amanzi kuma-capillaries ayancipha, futhi izinhlayiya ze-polymer zivinjelwe kancane kancane kuma-capillaries. Ingxube yezinhlayiyana ze-Adhesive/unhydrated zikasimende kanye ne-filler surface yakha ungqimba olugcwele eduze; ngaphansi kwesenzo sokusabela kwe-hydration, ukumuncwa kongqimba oluyisisekelo kanye nokuhwamuka komhlaba, amanzi abuye ancishiswe, futhi ungqimba olunqwabelene olwakhiwe luqoqana lube ifilimu, olubopha umkhiqizo wokusabela kwe-hydration kuNdawonye bakha isakhiwo senethiwekhi esiphelele. Uhlelo oluyinhlanganisela olwakhiwe yi-cement hydration kanye nokwakheka kwefilimu ye-latex powder ingathuthukisa ukumelana okuguquguqukayo kokuqhekeka kwe-putty ngokusebenzisa isenzo esihlangene.

 

I-putty esetshenziswa njengesendlalelo esishintshayo phakathi kokufakwa kodonga lwangaphandle nopende akufanele ibe namandla kunodaka lokuplasta, ngaphandle kwalokho ukuqhekeka kuzokwenzeka kalula. Kuwo wonke uhlelo lwe-insulation, ukuguquguquka kwe-putty kufanele kube phezulu kunaleyo yezinto eziyisisekelo. Ngale ndlela, i-putty ingakwazi ukuzivumelanisa kangcono ne-deformation ye-substrate futhi ivikele ukuguqulwa kwayo ngaphansi kwesenzo sezinto zangaphandle zemvelo, ikhulule ukugxila ekucindezelekeni, futhi inciphise amathuba okuqhekeka nokuxebuka kwe-coating.
