Ukwengeza ama-polymers kungathuthukisa ukungagxili, ukuqina, ukumelana nokuqhekeka kanye nokumelana nomthelela kodaka nokhonkolo.I-Permeability nezinye izici zinomphumela omuhle.Uma kuqhathaniswa nokuthuthukisa amandla aguquguqukayo namandla okubopha kodaka nokunciphisa ukuqina kwawo, umphumela we-latex powder ohlakazeka kabusha ekuthuthukiseni ukugcinwa kwamanzi kodaka nokuthuthukisa ukuhlangana kwawo kunomkhawulo.
I-polymer powder ehlakazeka kabusha ngokuvamile icutshungulwa ngokumiswa ngokufuthwa kusetshenziswa amanye ama-emulsion akhona.Inqubo yokuqala ukuthola i-polymer emulsion ngokusebenzisa i-emulsion polymerization, bese uyithola ngokumisa isifutho.Ukuze uvimbele ukuhlangana kwe-latex powder futhi uthuthukise ukusebenza ngaphambi kokumiswa kwesifutho, ezinye izithasiselo zivame ukungezwa, njengama-bactericides, izithasiselo zokomisa isifutho, ama-plasticizers, ama-defoamers, njll., ngesikhathi senqubo yokumisa isifutho, noma ngemva nje kokumiswa.I-ejenti yokukhulula yengezwa ukuvimbela ukunqwabelana kwempushana ngesikhathi sokugcinwa.
Ngokukhula kokuqukethwe kwempushana ye-latex ehlakazeka kabusha, lonke uhlelo luthuthukela kupulasitiki.Endabeni yokuqukethwe okuphezulu kwe-latex powder, isigaba se-polymer odakeni oluphulukisiwe kancane kancane sidlula umkhiqizo we-inorganic hydration, udaka luba noshintsho lwekhwalithi futhi lube umzimba onwebekayo, futhi umkhiqizo we-hydration kasimende uba "ukugcwalisa"..Ifilimu elakhiwe impushana ye-latex ehlakazeka kabusha esatshalaliswa kusixhumi esibonakalayo idlala enye indima ebalulekile, okungukuthi, ukuthuthukisa ukunamathela ezintweni okuxhunyanwa nazo, ezifanele izindawo okunzima ukunamathela kuzo, njengokumuncwa kwamanzi aphansi kakhulu noma Okungewona- izindawo ezimuncayo (ezifana nokhonkolo olubushelelezi nezinto ezibonakalayo zikasimende, amapuleti ensimbi, izitini ezilinganayo, izindawo zezitini eziqinile, njll.) kanye nezindawo zezinto eziphilayo (njengamabhodi e-EPS, amapulasitiki, njll.) kubaluleke kakhulu.Ngenxa yokuthi ukuhlangana kwezinamatheliso ezingaphili ezintweni ezisetshenziswayo kufinyelelwa ngomgomo wokushumeka ngomshini, okungukuthi, udaka lwe-hydraulic lungena ezikhaleni zezinye izinto, luqina kancane kancane, futhi ekugcineni lunamathisele udaka kulo njengokhiye oshunyekwe kukhiye.Ingaphezulu lezinto ezibonakalayo, endaweni engenhla okunzima ukuyibopha, ayikwazi ukungena ngokuphumelelayo ngaphakathi kwempahla ukuze yakhe ukushumeka okuhle kwemishini, ukuze udaka olunama-adhesive we-inorganic kuphela lungaboshelwe kulo ngokuphumelelayo, kanye nokubopha. Indlela ye-polymer ihlukile., I-polymer ihlanganiswe ebusweni bezinye izinto ngamandla e-intermolecular, futhi ayixhomeki ku-porosity yendawo (yebo, indawo enzima kanye nokwanda kokuxhumana kuzothuthukisa ukunamathela).
