Ingabe i-putty powder additive redispersible latex powder iwathuthukisa kanjani amandla ebhondi?

Ekukhiqizeni i-putty powder, sidinga ukusebenzisa i-latex powder ephinda ihlakazeka.Ukusetshenziswa kwalezi zimpushana ze-latex kungandisa amandla okubopha.Siyazi ukuthi uma sifuna ukukhiqiza i-putty powder yekhwalithi ephezulu, isilinganiso sefomula kufanele sifanele, futhi izithasiselo ezikuyo kufanele zisetshenziswe ngendlela efanele.Sisebenzisa impushana ye-latex ehlakazeka kabusha ukuze sithuthukise amandla, ngakho singawaqinisekisa kanjani lawa mandla?

Okokuqala, sidinga ukuqonda ukuthi iyini i-latex powder ehlakazeka kabusha nokuthi yenziwa kanjani.Umsebenzi wayo oyinhloko ukuthuthukisa amandla.Ukwakheka nakho kwenziwa nge-polymer emulsion bese kwengezwa izithasiselo ezahlukahlukene.Ngesikhathi esifanayo, i-colloid evikelayo kanye ne-anti-caking agent yengezwa.I-polymer iyafafazwa ukuze yakhe impushana egeleza mahhala ehlakazeka kabusha emanzini.Ngokuyinhloko sisetshenziselwa ukukhiqiza i-putty powder bese siyifaka odakeni lwe-powder owomile.

Ngesikhathi senqubo yokukhiqiza, i-latex powder e-redispersible ingaphinde ihlakazwe futhi ifakwe kabusha, bese ungqimba oluyisisekelo luthatha ngokuqhubekayo umswakama wamahhala ku-voids yangaphakathi yodaka futhi ludle ngokuqhubekayo, futhi indawo eqinile ye-alkaline ehlinzekwa usimende yenza i-latex. izinhlayiya zomile futhi zakha odakeni.Ifilimu eqhubekayo engancibiliki emanzini eyakhiwe ukuhlanganiswa kwezinhlayiya ze-monodisperse ku-emulsion ibe yinqwaba elinganayo.

Ngemva kokuhlakazwa, impushana ye-latex ehlakazeka kabusha iyi-spray-dried dispersion, efakwa emanzini ukuze yakhe ukuhlakazeka okuzinzile okunezakhiwo ezifanayo nokuhlakazeka kwasekuqaleni.Nokho, kunezimo ezithile zokwenziwa kwalezi zimpushana ze-latex.Kudingeka kwenziwe ngaphansi kwezimo zokushisa eziphezulu.Wonke ama-dispersions angaguqulwa abe izimpushana ze-latex ezihlakazeka kabusha.

Impushana ye-latex ehlakazeka kabusha ingaphinde ithuthukise ukusebenza komsebenzi wokwakha, futhi futhi kuyindima ebaluleke kakhulu ukwenza impushana ye-putty nodaka olomile esiwukhiqizayo kangcono ekwakhiweni.Ngemuva kokwengeza, ukumelana nokuklwebheka namandla okuguquguquka kodaka nakho kuthuthukisiwe, okungenza udaka lube yipulasitiki futhi lungelapheki kancane.
