I-RDP yodaka olungangeni manzi

Ihlakazeka kabushai-polymer powder RDP/VAEi-emulsion ye-polymer eye yabhekana nenqubo efanele yokumisa isifutho (kanye nokukhethwa kwezithasiselo ezifanele)Polymer ye-Powdery. Lapho i-polymer powder eyomile ihlangana namanzi, iba yi-emulsion futhi ingaphinda iphelelwe amanzi emanzini ngesikhathi sokumiswa kodaka nokuqina, ukuze izinhlayiya ze-polymer zenze isakhiwo sezinto ze-polymer odakeni, olufana nenqubo yesenzo se-polymer emulsion kanye ne-polymer emulsion. idlala indima yokuguqula odakeni lukasimende. I-emulsion dry modified mortar ibizwa ngokuthi i-dry mortar (eyaziwa nangokuthi ingxube eyomileed udaka, udaka olomile lokuxuba).

Ngenxa yokuthi i-powder eyomile ayidingi ukubhekwa njengokulungiswa kwe-emulsion ye-polymer, inkinga yokuzinza, inani elincane lokwengeza udaka lingafinyelela ukusebenza okudingekayo, futhi lingcono kune-emulsion kulula ukupakisha, ukugcinwa, ukuthutha nokuhlinzeka, i-antifreeze kanye akukho isikhutha, amagciwane, futhi usimende nesihlabathi okulungele-okuxutshwe eyenziwe single-component imikhiqizo emaphaketheni engeza izinzuzo ukusetshenziswa kwamanzi. Lapho isetshenziswa, isihlabathi, usimende, i-latex powder dry nezinye izithasiselo zixutshwa futhi zipakishwe kusenesikhathi, futhi udaka olomile olusebenza kangcono lungenziwa ngokushesha ngokungeza inani elithile lamanzi ekwakhiweni kwensimu. Umnyombo we-emulsion wokulungiselela impushana eyomile ilele kusayizi wezinhlayiya ze-polymer ezifana nezinhlayiya ze-emulsion polymer yasekuqaleni noma ukuhlakazeka kosayizi wezinhlayiyana. Ukwengeza inani elithile le-colloid yokuzivikela efana ne-polyvinyl alcohol ku-emulsion, ukuzei-polymer powder RDP/VAEingahlakazwa kabusha ibe yi-emulsion lapho ihlangana namanzi,i-polymer powder RDP/VAEbabe nokuhlakazeka okuhle kuphela ukuze kuqinisekiswe ukusebenza kahle kakhulu.i-polymer powder RDP/VAEetholakala ekuhlakazweni kuvame ukuba yimpushana emhlophe.

Izithako zayo zihlanganisa:

I-polymer resin: etholakala engxenyeni eyinhloko yei-polymer powder ehlakazeka kabushaizinhlayiya, futhi iyingxenye eyinhloko ye-redispersiblei-polymer powder RDP/VAEdlala indima.

Isengezo (ngaphakathi) : ngokuhlangana ne-resin ukuze kulungiswe inhlaka.

Isengezo (yangaphandle) : izinto ezengeziwe zengezwa ukuze kuthuthukiswe izakhiwo zokuhlakazeka kabushai-polymer powder RDP/VAE.

I-protective colloid: ungqimba lwe-hydrophilic material esongwe phezu kokuhlakazeka kabushai-polymer powder RDP/VAEizinhlayiya. Iningi le-colloid evikelayo ye-redispersiblei-polymer powder RDP/VAEi-polyvinyl alcohol.

I-Anti-caking agent: i-fine mineral filler, ikakhulukazi esetshenziselwa ukuvimbela ukugoqai-polymer powder ehlakazeka kabushaohlelweni lokugcina nezokuthutha kanye nokwenza lula ukuhamba kwei-polymer powder ehlakazeka kabusha(lahla isikhwama sephepha noma imoto yethangi).
