Basa relatex poda muputty poda uye dhaka risina mvura

Sechinhu chinonyanya kukosha chekushongedza mukushongedza, putty poda chinhu chepasi chekuyera madziro uye kugadzirisa, uye hwaro hwakanaka hwezvimwe zvekushongedza. Iyo yemadziro yepamusoro inogona kuchengetwa yakatsetseka uye yakafanana kuburikidza nekushandiswa kweputty poda, kuitira kuti zvirongwa zvekushongedza zvemangwana zviitwe zvirinani. Putty poda inowanzo umbwa nebase material, filler, mvura uye additives. Ndeapi mabasa makuru eiyo redispersible latex poda sechinhu chikuru chekuwedzera mune putty poda:

A. Kuvandudza kuvakwa;
B. Kuwedzera kuchengetedza mvura yekuvandudza hydration;
C. Kuwedzera kushanda;
D. Dzivisa kukurumidza kutsemuka.

② Mhedzisiro padhaka rakaomarara:

A. Deredza elastic modulus yedhaka uye kuwedzera kuwirirana kwechigadziko chepasi;
B. Wedzera kushanduka uye kuramba kuputika;
C. Kuvandudza hupfu hwekudurura kuramba;
D. Hydrophobic kana kuderedza kutorwa kwemvura;
E. Wedzera kunamatira kune base layer.

Mvura isingapindi mvura inoreva dhaka resimende rine zvakanaka kusapinda mvura uye kusapinda mvura mushure mekuomeswa nekugadzirisa reshiyo yedhaka uye kutora imwe nzira yekuvaka. Mvura isina mvura ine yakanaka yemamiriro ekunze kuramba, kusimba, kusamira, compactness, yakakwirira kunamatira uye yakasimba isingapinde mvura uye anti-corrosion maitiro.
