Indima ye-polymer powder ehlakazeka kabusha ku-putty powder

Indima yeezihlakazeka kabushai-polymerimpushanaku-putty powder: inokunamathela okuqinile kanye nezakhiwo zemishini, ukungangeni kwamanzi okuvelele, ukungena kwamanzi, nokumelana ne-alkali okuhle kakhulu nokumelana nokugqoka, futhi ingathuthukisa ukugcinwa kwamanzi futhi yandise Isikhathi Esivulekile sokuqina okuthuthukisiwe.

1. Umphumela wodaka olusanda kuxutshwa

1) Thuthukisa ukwakhiwa.

I-2) Ukugcinwa kwamanzi okwengeziwe ukuze kuthuthukiswe ukugeleza kukasimende.

3) Khulisa ukusebenza.

4) Gwema ukuqhekeka kusenesikhathi.

2. Umphumela wodaka oluqinile

I-1) Yehlisa i-elastic modulus yodaka futhi ukhulise ukuhambisana nesendlalelo sesisekelo.

2) Khulisa ukuguquguquka futhi umelane nokuqhekeka.

3) Thuthukisa ukumelana kokuwa kwempushana.

I-4) I-Hydrophobic noma ukunciphisa ukumuncwa kwamanzi.

I-5) Khulisa ukunamathela kwesendlalelo sesisekelo.

I-latex powder ehlakazeka kabusha yakha i-emulsion ye-polymer lapho ithintana namanzi.Phakathi nenqubo yokuxuba nokomisa, i-emulsion iphinda iphelelwe amanzi.I-latex powder isebenza ku-putty powder, futhi inqubo yokwakheka kwesistimu eyinhlanganisela ye-cement hydration kanye nokwakheka kwefilimu ye-latex powder iqedwa ngezinyathelo ezine:

①Uma impushana ye-latex ehlakazeka kabusha ixutshwa ngokulinganayo namanzi kumpushana oyimpuphu, ihlakazeka ibe yizinhlayiya ze-polymer ezinhle;

②Ijeli ye-cement kwakheka kancane kancane ngokusebenzisa ukugeleza kokuqala kukasimende, isigaba se-liquid sigcwele i-Ca (OH) 2 eyakhiwe ngesikhathi senqubo ye-hydration, futhi izinhlayiya ze-polymer ezakhiwe yi-latex powder zifakwa phezu kwejeli ye-cement / ingxube yezinhlayiya zikasimende ezingenamanzi;

③ Njengoba usimende uqhubeka u-hydrated, amanzi asezimbotsheni ze-capillary ayancipha, futhi izinhlayiya ze-polymer ziboshwe kancane kancane kuma-capillary pores, zakha ungqimba oluhlanganiswe ngokuqinile ebusweni bejeli likasimende / ingxube yezinhlayiya zikasimende ezingenamanzi kanye nokugcwalisa;

④ Ngaphansi kwesenzo sokusabela kwe-hydration, ukumuncwa kongqimba oluyisisekelo kanye nokuhwamuka kwendawo, umswakama uyancipha ngokwengeziwe, futhi izendlalelo ezinqwabelene ezakhiwe zihlanganiswa zibe ifilimu elincanyana, futhi imikhiqizo yokusabela kwe-hydration ihlanganiswe ndawonye ukuze yakhe isakhiwo senethiwekhi esiphelele.Uhlelo oluyinhlanganisela olwakhiwe yi-cement hydration kanye nokwakheka kwefilimu ye-latex powder kuthuthukisa ukumelana okuguquguqukayo kokuqhekeka kwe-putty.

Ngokombono wohlelo lokusebenza olusebenzayo, amandla e-putty asetshenziswa njengesendlalelo soguquko phakathi kwe-insulation yangaphandle kanye nokumbozwa kodonga lwangaphandle akufanele kube ngaphezu kodaka lokunamathisela, ngaphandle kwalokho kulula ukukhiqiza ukuqhekeka.Kuwo wonke uhlelo lwe-insulation, ukuguquguquka kwe-putty kufanele kube phezulu kunokwe-substrate.Ngale ndlela, i-putty ingakwazi ukuzivumelanisa kangcono nokuguquguquka kwe-substrate futhi ivikele ukuguqulwa kwayo ngaphansi kwesenzo sezinto zangaphandle zemvelo, ikhulule ukugxila ekucindezelekeni, futhi inciphise amathuba okuqhekeka nokuxebuka kwe-coating.
