VAE bakeng sa Tile Binder: Ho ntlafatsa ho khomarela le ho tšoarella
Li-copolymers tsa vinyl acetate-ethylene (VAE) li atisa ho sebelisoa e le li-binders tsa lithaele indastering ea kaho ho matlafatsa ho khomarela le ho tšoarella ha libopeho tsa sekhomaretsi sa lithaele. Mona ke kamoo VAE e ka sebelisoang ka katleho molemong ona:
- Ntlafatso ea Khomarelo: Li-polymers tsa VAE li ntlafatsa ho khomarela pakeng tsa lithaele le li-substrates ka ho etsa tlamo e matla le e tenyetsehang. Li khothalletsa ho kolobisa le ho hasana ha sekhomaretsi holim'a lithaele le karolo e ka tlaase, ho netefatsa kamano e haufi-ufi le ho matlafatsa matla a ho khomarela.
- Ho feto-fetoha ha maemo: Li-copolymers tsa VAE li fana ka mokhoa oa ho feto-fetoha ha libopeho tsa sekhomaretsi sa lithaele, tse li lumellang ho amohela metsamao e menyenyane le ho atolosa substrate le ho fokotseha ntle le ho senya ho khomarela. Ho feto-fetoha ha maemo ho thusa ho thibela ho phunyeha le ho senyeha ha lithaele, haholo-holo libakeng tse nang le khatello e phahameng ea maikutlo kapa tlas'a maemo a fetohang a tikoloho.
- Khanyetso ea Metsi: Likhomaretsi tsa lithaele tse thehiloeng ho VAE li bonts'a khanyetso e ntle ea metsi, li fana ka nako e telele le ts'ireletso khahlano le litaba tse amanang le mongobo joalo ka ho ruruha, ho loants'a le ho hola ha hlobo. Sena ke sa bohlokoa ka ho khetheha libakeng tse metsi tse kang likamore tsa ho hlapa, kichine le matamo a ho sesa.
- Matla a Phahameng a Bond: Li-polymers tsa VAE li kenya letsoho ho matlafatseng a matla a maqhama pakeng tsa lithaele le li-substrates, ho netefatsa hore ho kentsoe lisebelisoa tse tšepahalang le tse tšoarellang nako e telele. Ba ntlafatsa matla a momahano a matrix a sekhomaretsi, e leng se hlahisang litlamo tse matla le tse tšoarellang esita le tlas'a maemo a thata.
- Ho lumellana le Li-additives: Li-copolymers tsa VAE li lumellana le mefuta e mengata ea li-additives tse atisang ho sebelisoa ha ho etsoa lithaelese tsa sekhomaretsi, tse kang li-thickeners, plasticizers le fillers. Sena se lumella ho fetoha ha maemo ha ho etsoa le ho nolofalletsa ho iketsetsa li-adhesive tsa lithaele ho finyella litlhoko tse khethehileng tsa ts'ebetso le likhetho tsa kopo.
- Bonolo ba Kopo: Likhomaretsi tsa lithaele tse thehiloeng ho VAE li bonolo ho li sebelisa le ho sebetsa ka tsona, ka lebaka la ho tsitsa ha tsona, ho ata ha tsona hantle, le ho hanyetsa ho hotle ho sag. Li ka hasoa kapa tsa hasana ka ho lekana holim'a li-substrates, ho netefatsa hore li koahetsoe ka mokhoa o ts'oanang le botenya bo nepahetseng ba sekhomaretsi.
- Low VOC: Li-copolymers tsa VAE hangata li na le likhase tse tlase tsa "volatile organic compound" (VOC), e leng se etsang hore li se ke tsa silafatsa tikoloho 'me li lokele ho sebelisoa libakeng tse kahare moo ho amehang boleng ba moea.
- Netefatso ea Boleng: Khetha li-copolymers tsa VAE ho tsoa ho barekisi ba tsebahalang ba tsebahalang ka boleng ba bona bo tsitsitseng le tšehetso ea botekgeniki. Netefatsa hore VAE copolymer e kopana le maemo a amehang a indasteri le litlhokahalo tsa taolo, joalo ka litekanyetso tsa Machaba tsa ASTM bakeng sa liforomo tsa sekhomaretsi sa lithaele.
Ka ho kenyelletsa li-copolymers tsa VAE ho li-formulation tse khomarelang lithaele, bahlahisi ba ka finyella sekhomaretsi se phahameng, ho tšoarella, le ts'ebetso, e leng se etsang hore ho be le lisebelisoa tse ka tšeptjoang le tse tšoarellang nako e telele. Ho etsa liteko ka botlalo le mehato ea taolo ea boleng nakong ea ntlafatso ea tlhahiso ho ka thusa ho ntlafatsa ts'ebetso ea likhomaretsi tsa lithaele le ho netefatsa hore li loketse lits'ebetso tse ikhethileng le maemo a tikoloho.
