I-latex powder ephindwe kabusha iyimpushana etholakala ngokufafaza i-emulsion ye-polymer bese ingeza izinto eziguquliwe, ezingaphinde zihlakazwe ukuze zenze i-emulsion lapho ihlangana namanzi.I-latex powder ye-redispersible isetshenziswa ngokuyinhloko njengesengezo sodaka oluxutshwe okomile, olunemisebenzi yokuthuthukisa ukusebenza kodaka, ukuthuthukisa uketshezi, ukuthuthukisa ukuhlangana, nokwandisa amandla okubopha.Iwuhlobo olusha lwempahla ehambisana nemvelo.Njengamanje, impushana ye-latex idinga ukungezwa ekuhlanganisweni kwamathayili, ukufakwa odongeni lwangaphandle, ukuzilinganisa, impushana e-putty, njll.
I-polymer emulsion esetshenziswa ku-latex powder ehlakazeka kabusha ngokuyinhloko i-polymer emulsion eyakhiwe ngokungeza i-monomer eyodwa noma amabili ku-vinyl acetate njenge-monomer e-China.Njengamanje, i-vinyl acetate-ethylene copolymer emulsion, i-vinyl acetate - Ngokuyinhloko i-ethylene tertiary carbonate copolymer emulsion, izithasiselo zizokwengezwa ku-latex powder ekhiqizwa ukuthuthukisa i-anti-caking kanye ne-dispersibility.Kodwa-ke, ngenxa yesakhiwo se-vinyl acetate, amandla ayo okuqala namandla okuphulukisa amanzi awalungile mayelana nokunamathela kumabhodi okufakwayo kanye nama-substrates kasimende.
I-Acrylic emulsion inokumelana okuhle kwamanzi futhi isetshenziswa kabanzi embonini yezinto zokwakha, kodwa inqubo yayo yokomisa kanye ne-powder yokufafaza ayivuthiwe, futhi ingxenye yayo ku-emulsion powder e-dispersible incane kakhulu, futhi ukunamathela kwe-acrylic emulsion kumpofu, futhi akufanelekile. inamathele odakeni.Ukuthuthukiswa okunganele kwamandla okubopha kunciphisa ukusetshenziswa kwe-emulsion ye-acrylic.
Inhloso yenoveli i-acrylic latex powder kanye nendlela yokuyilungisa ukuthola imikhiqizo ye-latex powder enamandla amakhulu ahlangene kanye nokunamathela okuhle.
1. I-latex powder ephindwe kabusha inokubumbana okuhle kakhulu, okungathuthukisa ukuhlangana kodaka lokwakha, ukuthuthukisa ukunamathela phakathi kodaka kanye nezinto eziyisisekelo, futhi kuthuthukise ukusebenza.Ifanele izinto zokwakha kanye nodaka oludinga amandla aphezulu okubopha.ensimini, ithemba lemakethe libanzi.
2. Ohlelweni lokubunjwa kwempushana ye-latex ehlakazeka kabusha, izinhlobonhlobo zama-emulsions e-polymer asekelwe emulsion ye-acrylic ziyakhethwa futhi zixutshwe ngokwesilinganiso esifanele, esinganikeza ukudlala okugcwele ngezinzuzo zazo, ukuthuthukisa ukusebenza kwe-latex powder, futhi ukwandisa ububanzi be-latex powder.ububanzi besicelo.
3. Ekulungiseleleni i-latex powder ephindwe kabusha, uketshezi lwe-spray lushiswa ngokuqondile ngokushisa kwe-inthanethi, okuthuthukisa ukuphinda kuhlakazeke kwe-latex powder.
4. Kuhlelo lwefomula yempushana ye-latex ehlakazeka kabusha, izinhlobo ezimbili zezingxube ze-calcium carbonate, i-talcum powder, i-kaolin ne-silicon dioxide zikhethwa njengama-anti-caking agents anesilinganiso esikhulu se-1: 1-2, ukuze i-latex powder. izinhlayiya Ukugoqa kufana kakhulu futhi impahla yokulwa namakhekhe ye-latex powder iyathuthukiswa.
5. Ohlelweni lokwakhiwa kwempushana ye-latex ehlakazeka kabusha, eyodwa noma ingxube ye-silicone defoamer kanye ne-mineral oil defoamer ikhethwa njenge-defoamer ngesilinganiso esikhulu esingu-1: 1, esithuthukisa Isakhiwo sefilimu se-latex powder. kuthuthukisa amandla okubopha udaka.
6. Inqubo yokulungiselela i-latex powder ehlakazeka kabusha ilula futhi kulula ukuyibona intuthuko yezimboni.
