Redispersible latex powder (RDP) ke motsoako oa bohlokoa oa thepa ea mohaho o sebelisoang haholo ho li-adhesives tsa lithaele. Ha e ntlafatse feela thepa e sa tšoaneng ea li-adhesives tsa lithaele, empa e boetse e rarolla mefokolo e meng ea thepa e tloaelehileng ea tlamahano.
1. Ntlafatsa ho khomarela
E 'ngoe ea mesebetsi e ka sehloohong ea phofo ea latex e ka sebelisoang hape ke ho ntlafatsa matla a maqhama a likhomaretsi tsa lithaele. Likhomaretsi tsa setso tse thehiloeng ho samente li theha sehlahisoa se thatafalitsoeng ka mor'a metsi, se fana ka matla a itseng a tlamahano. Leha ho le joalo, ho tiea ha lihlahisoa tsena tse thata ho fokotsa ho khomarela. Redispersible latex powder e qhalakanngoa hape ka metsing ho etsa likaroloana tsa latex, tse tlatsang li-pores le mapetsong a thepa e entsoeng ka samente le ho etsa filimi e tsitsitseng e khomarelang. Filimi ena ha e eketse sebaka sa ho ikopanya feela, empa hape e fana ka sekhomaretsi tekanyo e itseng ea ho feto-fetoha ha maemo, kahoo e ntlafatsa haholo matla a ho kopanya. Ntlafatso ena e bohlokoa ka ho khetheha lits'ebetsong tsa lithaele tsa ceramic moo ho hlokahalang matla a phahameng a bond.
2. Ntlafatsa ho feto-fetoha ha maemo le ho hanyetsa crack
Redispersible latex phofo e ka fa likhomaretsi tsa lithaele ho fetoha habonolo le ho hanyetsa mapetso. Likhomaretsing, ho ba teng ha RDP ho etsa hore lesela le omisitsoeng la sekhomaretsi le be le elasticity e itseng, e le hore e khone ho mamella ho senyeha ho fokolang ho bakoang ke ho fetoha ha mocheso, substrate deformation kapa khatello ea kelello e ka ntle. Ts'ebetso ena e ntlafetseng e fokotsa kotsi ea ho petsoha kapa ho senya, haholo-holo lits'ebetsong tse kholo tsa lithaele kapa moo lithaele li behoang libakeng tsa khatello e phahameng.
3. Ntlafatsa ho thibela metsi
Ho hanyetsa metsi ho bohlokoa bakeng sa ts'ebetso ea nako e telele ea li-adhesive tsa lithaele. Redispersible latex powder ka katleho e thibela ho kenella ha metsi ka ho etsa marang-rang a teteaneng a polymer. Sena ha se ntlafatse feela ho hanyetsa metsi ha sekhomaretsi, empa se boetse se ntlafatsa bokhoni ba sona ba ho mamella lipotoloho tsa leqhoa, ho lumella sekhomaretsi sa lithaele ho boloka sekhomaretsi se setle le botsitso ba sebopeho libakeng tse mongobo.
4. Ntlafatsa kaho le lihora tsa ho bula
Redispersible latex phofo e ka boela ea ntlafatsa ts'ebetso ea kaho ea likhomaretsi tsa lithaele. Likhomaretsi tse kentsoeng ka RDP li na le lubricity le ts'ebetso e betere, li etsa hore kaho e be bonolo haholoanyane. Ka nako e ts'oanang, e boetse e eketsa nako e bulehileng ea sekhomaretsi (ke hore, nako e atlehang eo sekhomaretsi se ka khomarelang tile ka mor'a kopo). Sena se fa basebetsi ba kaho nako e eketsehileng ea ho sebetsa, ho thusa ho ntlafatsa katleho ea kaho le boleng.
5. Ntlafatsa ho hanyetsa boemo ba leholimo le ho tšoarella
Ho hanyetsa boemo ba leholimo le ho tšoarella ke lintlha tsa bohlokoa tse susumetsang ts'ebetso ea nako e telele ea li-adhesive tsa lithaele. Likaroloana tsa polymer ho RDP cross-link nakong ea ho folisa sekhomaretsi, ho etsa marang-rang a tsitsitseng haholo a polymer. Marang-rang ana a ka hanela ka katleho tšusumetso ea maemo a tikoloho a kang mahlaseli a ultraviolet, botsofali ba mocheso, khoholeho ea asiti le alkali, kahoo e ntlafatsa ho hanyetsa boemo ba leholimo le ho tšoarella ha sekhomaretsi sa lithaele le ho lelefatsa bophelo ba eona ba tšebeletso.
6. Fokotsa ho monya ha metsi le ho ntlafatsa ho hanyetsa hlobo
Redispersible latex powder e ka boela ea fokotsa sekhahla sa ho monya metsi ha likhomaretsi tsa lithaele, kahoo ea fokotsa ho hloleha ha lera la bonding ho bakoang ke katoloso ea hygroscopic. Ho phaella moo, karolo ea hydrophobic polymer ea RDP e ka thibela ho hōla ha hlobo le likokoana-hloko tse ling, ka tsela eo, e ntlafatsa thepa e thibelang hlobo ea li-adhesives tsa lithaele. Sena se bohlokoa haholo-holo libakeng tse mongobo kapa tse mongobo o mongata, joalo ka liphaposi tsa ho hlapa le li kichine.
7. Ikamahanya le mefuta e fapaneng ea substrates
Redispersible latex phofo e fa sekhomaretsi sa lithaele hantle se ikamahanyang le maemo a mangata. Ebang ke lithaele tse boreleli tse boreleli, lithaele tsa ceramic tse monyang metsi a mangata, kapa likaroloana tse ling tse kang boto ea samente, boto ea gypsum, joalo-joalo, likhomaretsi tse kentsoeng ka RDP li ka fana ka thepa e ntle ea tlamahano. Sena se lumella mefuta e mengata ea lisebelisoa pakeng tsa mefuta e fapaneng ea lithaele le li-substrates.
8. Tšireletso ea tikoloho
Lisebelisoa tsa morao-rao tsa mohaho li ntse li hatisa ka ho eketsehileng tšireletso ea tikoloho. Redispersible latex powder hangata e entsoe ka thepa e baballang tikoloho joalo ka joala ba polyvinyl le acrylate. Ha e na li-solvents tse kotsi le litšepe tse boima 'me e finyella litlhoko tsa thepa ea mohaho o motala. Ho feta moo, RDP ha e lokolle li-volatile organic compounds (VOC) nakong ea kaho, ho fokotsa kotsi ho basebetsi ba kaho le tikoloho.
Tšebeliso ea phofo ea latex e ka sebelisoang hape ka li-adhesive tsa ceramic tile e ntlafatsa haholo ts'ebetso ea kakaretso ea sekhomaretsi, ho kenyelletsa ho khomarela, ho feto-fetoha ha maemo, ho hanyetsa metsi, ho haha, ho hanyetsa boemo ba leholimo, ho hanyetsa hlobo le ho sireletsa tikoloho. Lintlafatso tsena ha li ntlafatse feela katleho ea kaho le katleho, empa hape li eketsa bophelo ba tšebeletso ea li-adhesives tsa lithaele, ho li lumella ho ikamahanya le mefuta e mengata ea maemo a kopo. Ka hona, RDP e maemong a bohlokoa haholo mekhoeng ea sekhomaretsi ea lithaele tsa ceramic, e fanang ka tšehetso e matla bakeng sa ho ntlafatsa boleng ba merero ea kaho.
