Lefapheng la kaho, likhomaretsi tsa lithaele tse entsoeng ka samente li phetha karolo ea bohlokoa ho netefatsa hore lithaele li tšoarella le ho phela nako e telele. Likhomaretsi tsena li bohlokoa bakeng sa ho kopanya lithaele ka thata ho li-substrates tse kang konkreite, seretse kapa libaka tse teng tsa lithaele. Har'a likarolo tse fapa-fapaneng tsa li-adhesives tse entsoeng ka samente, hydroxypropyl methylcellulose (HPMC) e hlahella e le motsoako oa bohlokoa ka lebaka la thepa ea eona e mengata le tlatsetso ho ts'ebetsong ea mokhoa oa ho khomarela.
1. Utloisisa HPMC:
Hydroxypropylmethylcellulose (HPMC) ke nonionic cellulose ether e nkiloeng ho li-polymers tsa tlhaho, haholo-holo selulose. Hangata e sebelisoa ka thepa ea kaho e le mofetoleli oa rheology, moemeli oa ho boloka metsi le sekhomaretsi. HPMC e entsoe ka letoto la liphetoho tsa lik'hemik'hale ho selulose, e leng se hlahisang polima e qhibilihang ka metsing e nang le thepa e ikhethang e loketseng mefuta e fapaneng ea likopo indastering ea kaho, ea meriana le ea lijo.
2.Seabo sa HPMC ho sekhomaretsi sa lithaele tse thehiloeng ho samente:
Poloko ea Metsi: HPMC e na le pokello e ntle ea metsi, e lumellang sekhomaretsi ho boloka botsitso le ts'ebetso e nepahetseng ha nako e ntse e ea. Thepa ena ke ea bohlokoa ho thibela ho omisoa pele ho nako ea sekhomaretsi, ho netefatsa hore ho na le metsi a lekaneng a likarolo tsa samente, le ho matlafatsa matla a maqhama pakeng tsa tile le substrate.
Phetoho ea Rheology: HPMC e sebelisoa e le mofetoleli oa rheology, e amang boitšoaro ba phallo le viscosity ea li-adhesives tse thehiloeng ho samente. Ka ho laola viscosity, HPMC e ka sebelisa sekhomaretsi habonolo, ea khothaletsa esita le tšireletso le ho fokotsa kotsi ea ho thella ha lithaele nakong ea ho kenya. Ho feta moo, e thusa ho theola 'mele le ho ntlafatsa ho ata ha likhomaretsi, ka hona ho ntlafatsa ts'ebetso le ho fokotsa matla a mosebetsi.
Matlafatso a Matlafatsoa: HPMC e sebetsa e le sekhomaretsi, e khothalletsang ho khomarela pakeng tsa sekhomaretsi le bokaholimo ba lithaele le substrate. Sebopeho sa eona sa limolek'hule se etsa filimi e khomarelang ha e le metsi, ka katleho e kopanya sekhomaretsi ho lisebelisoa tse sa tšoaneng, ho akarelletsa le li-ceramics, porcelain, majoe a tlhaho le likaroloana tsa konkreite. Thepa ena ke ea bohlokoa bakeng sa ho finyella sekhomaretsi se matla, se tšoarellang nako e telele, ho thibela sekhahla sa lithaele le ho netefatsa botšepehi ba sebopeho sa holim'a tile.
Crack Resistance: HPMC e fana ka sekhomaretsi sa lithaele tse thehiloeng ho samente 'me e ntlafatsa ho hanyetsa ha crack. Hobane lithaele li tlas'a khatello ea mochini le ho sisinyeha ha meralo, sekhomaretsi se tlameha ho ba serethe se lekaneng ho amohela metsamao ena ntle le ho phatloha kapa delamination. HPMC e ntlafatsa ho feto-fetoha ha matrix a sekhomaretsi, ho fokotsa monyetla oa ho phunyeha le ho etsa bonnete ba ho tšoarella ha lisebelisoa tsa lithaele, haholo-holo libakeng tse nang le sephethephethe se phahameng kapa libaka tse atisang ho fetoha mocheso.
Ho tšoarella le ho hanyetsa Boemo ba Boemo ba Leholimo: Keketso ea HPMC e ntlafatsa ho tšoarella le ho hanyetsa boemo ba leholimo ba likhomaretsi tsa lithaele tse thehiloeng ho samente. E fana ka khanyetso e eketsehileng ea ho kenella ha metsi, lipotoloho tsa ho qhibiliha ha leqhoa le ho pepeseha ha lik'hemik'hale, ho thibela ho senyeha le ho boloka botšepehi ba holim'a lithaele lits'ebetsong tsa ka hare le tsa ka ntle. Ho feta moo, HPMC e thusa ho fokotsa litlamorao tsa boemo ba leholimo, ho netefatsa hore lisebelisoa tsa lithaele li lula li le ntle ha nako e ntse e ea.
3. Melemo ea HPMC ho likhomaretsi tsa lithaele tse thehiloeng ho samente:
TLHOKOMELISO E Ntlafetseng: HPMC e ntlafatsa ts'ebetso ea li-adhesives tse thehiloeng ho samente, e etsa hore ho be bonolo ho kopanya, ho sebetsa le ho boreleli. Likonteraka li ka finyella liphello tse tsitsitseng ka boiteko bo fokolang, ho boloka nako le chelete nakong ea ts'ebetso ea ho kenya.
Matla a Matlafatsoa a Bond: Ho ba teng ha HPMC ho khothalletsa maqhama a matla pakeng tsa tile, sekhomaretsi le substrate, e leng se hlahisang matla a holimo a tlamahano le ho fokotsa kotsi ea ho thibela lithaele kapa ho hlōleha. Sena se tiisa ts'ebetso ea nako e telele le botsitso ba holim'a tile libakeng tse sa tšoaneng.
Mefuta-futa: Likhomaretsi tsa lithaele tse thehiloeng ho HPMC li sebetsa ka mokhoa o fapaneng 'me li loketse ho sebelisoa mefuteng e fapaneng ea lithaele, boholo le li-substrates. Hore na ba kenya lithaele tsa ceramic, porcelain, majoe a tlhaho kapa lithaele tsa mosaic, borakonteraka ba ka itšetleha ka likhomaretsi tsa HPMC ho fana ka liphetho tse tsitsitseng ho tloha morerong o mong ho ea ho o mong.
Tšebelisano: HPMC e lumellana le li-additives le li-admixtures tse ling tse atisang ho sebelisoa ho khomarela lithaele tsa samente, tse kang li-modifiers tsa latex, li-polymers le lik'hemik'hale tse matlafatsang ts'ebetso. Khokahano ena e lumella litlhophiso tse ikhethileng ho fihlela litlhoko tse ikhethileng tsa ts'ebetso le litlhoko tsa projeke.
Sustainability: HPMC e nkiloe mehloling ea selulose e ka nchafatsoang, e e etsa khetho e ntle ea tikoloho bakeng sa thepa ea moaho. Ho senyeha ha eona le tšusumetso e tlase ea tikoloho li kenya letsoho mekhoeng ea moaho e tsitsitseng le matsapa a ho aha botala.
4. Tšebeliso ea HPMC sekhomaretsing sa lithaele tse thehiloeng ho samente:
HPMC e sebelisoa haholo mefuteng e fapaneng ea likhomaretsi tse thehiloeng ho samente ho kenyelletsa:
Standard Thin Form Mortar: HPMC e atisa ho sebelisoa ka seretse se tloaelehileng sa sebopeho se tšesaane bakeng sa ho kopanya lirafshoa le lithaele tsa ceramic ho li-substrates tse kang konkreite, li-screeds le liboto tse tšehetsang samente. Mehaho ea eona ea ho boloka metsi le ho khomarela e netefatsa ts'ebetso e tšepahalang bakeng sa ho kenya lithaele ka hare le ka ntle.
Sekhomaretsi sa Lithaele se Seholo sa Format: Lits'ebetsong tse kenyelletsang lithaele tse nang le sebopeho se seholo kapa lithaelese tsa majoe a tlhaho tse boima, li-adhesives tse thehiloeng ho HPMC li fana ka matla a matla a tlamahano le ho hanyetsa mapheo, ho ikamahanya le boima le litšobotsi tsa thaele.
Flexible Tile Adhesives: Bakeng sa lits'ebetso tse hlokang ho tenyetseha le ho holofala, joalo ka ho kenya li-substrates tse tloaetseng ho sisinyeha kapa ho atolosoa, HPMC e ka etsa likhomaretsi tse tenyetsehang tsa lithaele tse ka mamellang khatello ea sebopeho le maemo a tikoloho ntle le ho ama ho khomarela. ho lekana kapa ho tšoarella.
Hydroxypropyl methylcellulose (HPMC) e phetha karolo ea bohlokoa ho thehoeng le ts'ebetsong ea li-adhesive tsa lithaele tse entsoeng ka samente, ho fana ka likarolo tse sa tšoaneng le melemo e hlokahalang bakeng sa ho kenya lithaele ka katleho. Ho tloha ho matlafatsa ho khomarela le matla a tlamo ho ntlafatsa ts'ebetso le ho tšoarella, HPMC e thusa ho ntlafatsa boleng, botšepehi le bophelo bo bolelele ba lithaele tsa ceramic mererong e fapaneng ea kaho. Ha indasteri ea kaho e ntse e tsoela pele ho beha ts'ebetso, ts'ebetso le ts'ebetso pele, bohlokoa ba HPMC ho likhomaretsi tsa lithaele tse thehiloeng ho samente e ntse e le ntho ea bohlokoa, e tsamaisang boqapi le tsoelopele ea theknoloji ea ho kenya lithaele.
