Redispersible polymer poda inonatsiridza kusasimba kwechinyakare simende dhaka senge brittleness uye yakakwirira elastic modulus, uye inopa simende dhaka zviri nani kuchinjika uye tensile bond simba rekuramba uye kunonoka kuumbwa kwekutsemuka mudhaka sesimende. Sezvo iyo polymer uye dhaka zvichiumba inopindirana network chimiro, inoenderera polymer firimu inoumbwa mumapores, iyo inosimbisa chisungo pakati peaggregates uye ichivharira mamwe mapores mudhaka. Naizvozvo, kushanda kwedhaka rakaomeswa rakagadziridzwa rinovandudzwa zvikuru pane resamende dhaka.
Sechinhu chinonyanya kukosha chekushongedza mukushongedza, wall putty ibasa rekugadzirisa madziro uye kugadzirisa, uye ndiyo nheyo yakanaka yezvimwe zvekushongedza. Iro remadziro rinogona kuchengetwa rakatsetseka uye rakafanana nekuisa madziro putty, kuitira kuti inotevera yekushongedza purojekiti iitwe zvirinani. Wall putty inowanzo umbwa nebase material, filler, mvura uye additives. Ndeapi mabasa makuru ezve dispersible polymer poda sechinhu chikuru chekuwedzera mumadziro putty poda?
① Mhedzisiro padhaka nyowani;
A, Kuvandudza maitiro ekuvaka;
B, Ipa imwezve kuchengetedza kwemvura inovandudza hydration;
C, Wedzera kushanda;
D, Dzivisa kukurumidza kutsemuka
② Mhedzisiro pakuomesa dhaka:
A, Deredza elastic modulus yedhaka uye kuwedzera kukodzera kwayo kuenderana ne base layer;
B, Wedzera kuchinjika uye kuramba kutsemuka;
C, Kuvandudza kuramba kwehupfu kudonha.
D, Mvura inodzinga kana kuderedzwa kutorwa kwemvura
E, Wedzera kunamatira kune base layer.
