I-latex ebunjiwe ye-latex enamanye ama-inorganic ama-lime (anjengesimende, i-lime evuthayo, i-gypsum, njll.) Futhi ama-aggregate ahlukahlukene, ama-ether, i-ejenti, njll.) Ukuxubana ngokomzimba ukwenza ngodaka oluhlanganisiwe. Lapho kufakwa udaka oluhlanganisiwe emanzini bese kushukumisa, izinhlayiya ze-latex powder zizohlakazwa emanzini ngaphansi kwesenzo se-colloid evikela i-hydrophilic kanye ne-mehear mehear. Isikhathi esidingekayo se-towx evamile ye-latex ye-latisparible ukuhlakazeka imfushane kakhulu, futhi le nkomba yesikhathi sokuphinda ibuye ibe yipharamitha ebalulekile yokuhlola ikhwalithi yayo. Esigabeni sokuqala sokuxuba, i-latex powder isivele iqalile ukuthinta i-Rheology kanye nokusebenza kodaka.
Ngenxa yezimpawu ezihlukile kanye nokuguqulwa kwe-latex ye-latex ngayinye, lo mphumela uhlukile futhi, abanye banomphumela wokungena kosizo, futhi abanye banethonya le-Thixetropy elikhulayo. Indlela yethonya layo ivela ezicini eziningi, kufaka phakathi ithonya le-latex powder ebudlelwaneni bamanzi ngesikhathi sokuhlakazeka, ithonya lokuvezwa okuhlukile kwe-latex powder ngemuva kokuvikela, nethonya lamabhande kasimende kanye namabhande wamanzi. Amathonya afaka phakathi ukwanda kokuqukethwe komoya kudaka kanye nokusatshalaliswa kwama-bubble amoya, kanye nethonya lezithayo zalo nokuxhumana nezinye izithasiselo. Ngakho-ke, ukukhetha okwenziwe ngezifiso nokuhlukaniswa kwe-latex powder evuselelayo kuyindlela ebalulekile yokuthinta ikhwalithi yomkhiqizo. Iphuzu lokubuka elivame kakhulu ukuthi i-latex evuselelwayo ye-latex ivame ukukhulisa okuqukethwe komoya kodaka, ngaleyo ndlela kuthambisa ukwakhiwa kodaka, ikakhulukazi ukuvela lapho kuvimbela khona ukuthuthuka kodaka, ngaleyo ndlela kuthuthukise ukusebenziseka kodaka. Kamuva, udaka olumanzi oluqukethe i-latex powder dispersion lusetshenziswa endaweni yokusebenza. Ngokuncishiswa kwamanzi emazingeni amathathu - ukumuncwa kwesendlalelo sesisekelo, ukusetshenziswa kwamanzi okusimende kwe-hydration, kanye nezinhlayiya kancane kancane kancane, kuhlangana kancane kancane, bese ekugcineni kuba yifilimu eqhubekayo ye-polymer. Le nqubo yenzeka ikakhulukazi kuma-pores odaka nobuso bokuqina.
Kufanele kugcizelelwe ukuthi ukwenza le nqubo kungaphenduki, okungukuthi, lapho amafilimu e-polymer ahlangana khona amanzi futhi, ngeke ahlakazeke futhi, futhi i-colloid evikela i-latex ye-latex ye-latex. Le akuyona inkinga ohlelweni luka-Alkaline Cement Jaumer, ngoba luzotholwa yi-Alkali ekhiqizwe yi-Conment Hydration, futhi ngasikhathi sinye, ngaphandle kokuvikelwa kwezinto ezingekho emthethweni ze-collooids, ezingafakwanga ngaphansi kwezimo ze-latex ye-latex, kodwa futhi ngaphansi kwezimo zokucwiliselwa kwamanzi okude. Kuzinhlelo ezingezona ze-alkaline, ezinjengezinhlelo ze-gypsum noma amasistimu anabahlali kuphela, ngasizathu simbe kusatshalaliswa kwefilimu yesikhathi eside emanzini, kanti ama-polymer asasetshenziselwa ukumelana namanzi ahlukile, akuthinti ukusetshenziswa kwempuphu ye-latex ehlukile kulezi zinhlelo.
Ngokwakheka kwefilimu lokugcina le-polymer, uhlelo lwezinhlaka ezakhiwa ama-Inorganic ne-Organic Binders yakhelwe ngodaka lwelapha, okungukuthi, izinto ze-hydraulic zakha i-brittle and hard powder, futhi i-latex evuselelayo ye-latex yakha ifilimu phakathi kwegebe kanye nendawo eqinile. Ukuxhumana okuguquguqukayo. Lolu hlobo lokuxhumana lungacatshangwa njengokuxhumeke kumathambo aqinile ngemithombo eminingi emincane. Njengoba amandla ashubile efilimu le-polymer resin esungulwe yi-latex powder ngokuvamile i-magnituture ephakeme kunaleyo yezinto zokwakha i-hydraulic, amandla odaka uqobo, okungukuthi, ubumbano tholwa. Njengoba ukuguquguquka nokuqina kwe-polymer kuphakeme kakhulu kunalokho kwesakhiwo esiqinile njengokosimende, ukuwohloka kodaka kuyathuthukiswa, futhi umphumela wokuxineka kwengcindezi ngcono kakhulu, ngaleyo ndlela enze ngcono ukumelana nodaka kodaka.
