Ngaba i-putty powder additive redispersible latex powder iphucula njani amandla ebhondi?

Kwimveliso ye-putty powder, kufuneka sisebenzise i-latex powder ephindwe kabini. Ukusetyenziswa kwezi powders latex kunokunyusa amandla okudibanisa. Siyazi ukuba ukuba sifuna ukuvelisa umgangatho ophezulu we-putty powder, umlinganiselo wefomula kufuneka ufanelekile, kwaye izongezo ezikulo kufuneka zisetyenziswe ngokufanelekileyo. Sisebenzisa i-latex powder ehlaziywayo ukuphucula amandla, ngoko sinokuqinisekisa njani la mandla?

Okokuqala, kufuneka siqonde ukuba yintoni i-latex powder ephinda idiphanelwe kwaye yenziwa njani. Umsebenzi wayo oyintloko kukuphucula amandla. Ukubunjwa kwenziwa kwakhona nge-polymer emulsion kwaye ke izongezelelo ezahlukeneyo zongezwa. Ngexesha elifanayo, i-colloid ekhuselayo kunye ne-anti-caking agent yongezwa. I-polymer i-spray-yomisiwe ukwenza i-powder-flowing-free-dispersible emanzini. Sisetyenziswa ikakhulu ukuvelisa umgubo weputty kwaye songeze kudaka olomileyo lomgubo.

Ngexesha lenkqubo yokuvelisa, i-latex powder ehlaziywayo inokuphinda isasazwe kwaye iphinde i-emulsified, kwaye emva koko isiseko sesiseko siqhubeka sithatha ukufuma okukhululekile kwi-voids yangaphakathi yodaka kwaye idla ngokuqhubekayo, kwaye indawo eqinile ye-alkaline ebonelelwa ngesamente yenza i-latex. amasuntswana omile kwaye enze udaka. Ifilimu eqhubekayo enganyibilikiyo emanzini eyenziwe ngokuxutywa kweengqungquthela ze-monodisperse kwi-emulsion ibe yi-homogeneous mass.

Emva kokusabalalisa, i-latex powder ehlaziywayo yi-spray-dried dispersion, eyongezwa emanzini ukuze yenze i-dispersion ezinzileyo kunye neempawu ezifanayo njenge-dispersion yasekuqaleni. Nangona kunjalo, kukho iimeko ezithile zokuveliswa kwezi powders latex. Kufuneka iqhutywe phantsi kweemeko eziphezulu zokushisa. Zonke ii-dispersions zinokuguqulwa zibe ngumgubo welatex ophinda uhlakazwe.

I-latex powder ephinda iphinde ikwazi ukuphucula ukusebenza kolwakhiwo, kwaye ikwayindima ebaluleke kakhulu ukwenza i-putty powder kunye nodaka olomileyo esivelisa ngcono ekwakhiweni. Emva kokongezwa, ukuxhathisa ukukrazula kunye namandla okuguquguquka kodaka nawo aphuculwe, anokwenza udaka lweplastiki luninzi kwaye lunyangeke.
