Impushana ye-latex ehlakazeka kabusha njengesithako esibalulekile sodaka oluxutshwe okomile

I-latex powder ehlakazeka kabusha iwukuhlakazwa kwempushana okwenziwe nge-emulsion ye-polymer eguquliwe ngokumisa isifutho. Inokungena kahle kakhulu futhi ingaphinda ifakwe emulsion ye-polymer ezinzile ngemva kokukhululwa kwamanzi. I-organic chemistry ifana ncamashi nelotion yokuqala yokuthambisa. Ngakho-ke, kuba nokwenzeka ukukhiqiza udaka oluphezulu lwempuphu eyomile, ngaleyo ndlela kuthuthukiswe ukusebenza kodaka lukasimende.

I-latex powder ehlakazeka kabusha iyisengezo esisebenzayo esibalulekile sodaka. Ingathuthukisa ukusebenza kodaka, yandise amandla acindezelayo odaka lukasimende, ithuthukise amandla okubopha usimende namabhodi ahlukahlukene, futhi ithuthukise amandla odaka lukasimende. Ukuthamba nokukhubazeka, amandla aqinile, amandla acindezelayo, ukumelana nokuhuzuka, i-ductility, umjaho wokubambelela kanye nekhono lokuvala amanzi, kanye nokwakheka. Ukwengeza, i-latex powder yemvelo ene-repellency yamanzi ingenza udaka lukasimende lube nokuphikiswa okuhle komswakama.

Thuthukisa ukuhlangana kodaka lukasimende ekwakhiweni kobunjiniyela. Ngemva kokwakhiwa kodaka lukasimende olusanda kuxutshwa noketshezi lwe-latex powder dispersion liquid, okuqukethwe kwamanzi kuzokwehla kancane kancane ngokugayeka nokumuncwa kwamanzi ngesisekelo, ukusetshenziswa kokusabela kokuqina, kanye nokuhwamuka emoyeni. , izinhlayiya zisondela kancane kancane, amakhasi ayafiphala kancane kancane, futhi kancane kancane ahlanganiswa omunye nomunye. Ekugcineni, i-polymer is demulsified. Yonke inqubo ye-polymer demulsification ihlukaniswe yaba izixhumanisi ezintathu. Ku-emulsion yokuqala yokuthambisa, izinhlayiya ze-polymer zisesimweni sokunyakaza kwe-Brownian. Hambisa ngokukhululeka, kanye nokushintshashintsha kwamanzi, ukunyakaza kwezinhlayiya ngokwemvelo kungaphansi kwemingcele eyengeziwe, ukungezwani kwamanzi negesi kugqugquzela ukuba zihlele ndawonye kancane kancane, isigaba sesibili, lapho izinhlayiya ziqala ukuthintana, inethiwekhi Amanzi amise okwemvelo ayashintshashintsha ngama-capillaries, futhi amandla asekelayo anezimbobo eziphakeme akhululwe ebusweni bezinhlayiya abangela ukuwohloka kwezinhlayiya ze-latex zemvelo ukuze zihlangane ndawonye, ​​futhi amanzi asele agcwalisa ama-pores, futhi ulwelwesi cishe lwakhiwe. . Isinyathelo sesithathu Isinyathelo sokugcina siwukwenza ukusakazeka kwama-molecule e-polymer (ngezinye izikhathi okubizwa ngokuthi ukuzinamathisela) kwakha ifilimu yangempela eqhubekayo phakathi nenqubo ye-demulsification.
