Ukuhlaziywa Kwezakhiwo Nemithelela Yempushana Ye-latex Ehlakazeka Kabusha

Umkhiqizo we-latex powder ohlakazeka kabusha uyimpushana encibilika kabusha encibilika emanzini, eyi-copolymer ye-ethylene ne-vinyl acetate, futhi isebenzisa utshwala be-polyvinyl njenge-colloid evikelayo. Ngenxa yomthamo ophezulu wokubopha kanye nezakhiwo eziyingqayizivele zama-polymer powders ahlakazeka kabusha, njengalokhu: ukumelana namanzi, ukwakhiwa nokufakwa kokushisa, njll., ububanzi bokusebenza kwabo bubanzi kakhulu.

Impushana ye-latex ehlakazeka kabusha isetshenziswa kakhulu kulokhu: i-putty powder yangaphakathi nangaphandle, ingcina yethayela, i-ejenti yokukhomba i-tile, i-ejenti yokusebenzelana kwempushana eyomile, udaka lwangaphandle olufakwa odongeni, udaka oluzilinganisa, udaka lokulungisa, udaka lokuhlobisa, udaka olungangeni manzi, njll. hlanganisa udaka. i

Redispersible latex powder iyisithako esiluhlaza, esivumelana nemvelo, songa amandla okwakha, ikhwalithi ephezulu yezinto eziningi zokwakha okuyimpushana, futhi iyisengezo esibalulekile nesibalulekile esisebenzayo sodaka oluxutshwe okomile. Ingathuthukisa ukusebenza kodaka, ikhulise amandla odaka, ithuthukise amandla okubopha phakathi kodaka nama-substrates ahlukahlukene, ithuthukise ukuguquguquka nokusebenza kahle, amandla acindezelayo, amandla aguquguqukayo, ukumelana nokugqoka, ukuqina, ukunamathela kodaka Relay namandla okugcina amanzi, ukwakheka. Ngaphezu kwalokho, i-hydrophobic latex powder ingenza udaka lungangeni manzi kakhulu.

Indima ye-latex powder ehlakazeka kabusha:

1. Ngemva kokuhlakazwa, i-latex powder ehlakazeka kabusha yenza ifilimu futhi isebenze njenge-adhesive yesibili ukuthuthukisa umphumela;

2. I-colloid evikelayo imuncwa uhlelo lodaka (ngeke ichithwe ngamanzi ngemva kokwakhiwa kwefilimu, noma "ukuhlakazeka kwesibili";

3. I-resin ye-polymer eyenza ifilimu isakazwa kulo lonke uhlelo lodaka njengento yokuqinisa, ngaleyo ndlela ikhulise ukuhlangana kodaka; i-latex powder ehlakazeka kabusha iwuhlobo lwe-emulsion ekhethekile eyomisiwe (i-polymer) eyenziwe nge-Powder binder. Le powder ingaphinde ihlakazeke ngokushesha ukuze yenze i-emulsion ngemva kokuxhumana namanzi, futhi inezakhiwo ezifanayo njenge-emulsion yokuqala, okungukuthi, ifilimu ingakhiwa ngemva kokuba amanzi eqhuma. Le filimu inokuguquguquka okuphezulu, ukumelana nesimo sezulu esiphezulu kanye nokumelana nokunamathela okuhlukahlukene okuphezulu kuma-substrates.
