Kamano pakeng tsa HPMC le tile grout

1. Selelekela sa Hydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl Methylcellulose (HPMC)ke ether e seng ea ionic cellulose e sebelisoang haholo ho thepa ea mohaho, meriana, lijo, lik'hemik'hale tsa letsatsi le letsatsi le liindasteri tse ling. E entsoe ka thepa ea tlhaho ea polymer ka phetoho ea lik'hemik'hale 'me e na le ho qhibiliha ha metsi hantle, ho teteaneng, ho boloka metsi, ho etsa filimi le botsitso ba ho emisa. Sebakeng sa thepa ea mohaho, HPMC e sebelisoa haholo-holo ka seretse se omeletseng, sekhomaretsi sa lithaele, putty powder, grout, joalo-joalo ho ntlafatsa ts'ebetso ea kaho le ho ntlafatsa boleng ba sehlahisoa sa ho qetela.

2. Mosebetsi le ho hlophisoa ha tile grout

Tile grout ke thepa e sebelisetsoang ho tlatsa lekhalo pakeng tsa lithaelese, tse nang le mesebetsi ea ho ntlafatsa aesthetics, ho thibela metsi, ho hanyetsa hlobo le ho hanyetsa ho phatloha. Likarolo tse kholo tsa grout li kenyelletsa:
Samente kapa resin: joalo ka ntho e ka sehloohong e tlamang, e fanang ka matla le boima;
Filler: joalo ka lehlabathe la quartz, calcium carbonate, joalo-joalo, e sebelisetsoang ho ntlafatsa ho hanyetsa ho roala le botsitso ba sebopeho sa grout;
Li-additives: tse kang HPMC, latex powder, pigment, joalo-joalo, tse fanang ka ts'ebetso e ntle ea kaho ea grout, ho boloka metsi, ho hanyetsa ho fokotseha le ho tšoarella.

3. Karolo ea HPMC ho li-tile grout

Leha palo ea HPMC e kenyellelitsoeng ho tile grout e nyane, karolo ea eona e bohlokoa, haholo e bonts'oa likarolo tse latelang:

(1) Ho boloka metsi

HPMC e na le bokhoni bo botle ba ho boloka metsi. Ka grout, e ka liehisa mouoane oa metsi, ea ntlafatsa ts'ebetso ea hydration ea samente, samente e nang le metsi ka ho feletseng, ea ntlafatsa ho khomarela le matla a grout, le ho fokotsa ho phunyeha le phofo e bakoang ke tahlehelo e potlakileng ea metsi.

(2) Ntlafatsa tšebetso ea kaho

HPMC e ka ntlafatsa rheology ea grout, ea etsa hore slurry e be bonolo ho sisinyeha le ho e sebelisa, ho ntlafatsa boreleli ba kaho, le ho qoba mathata a kang agglomeration le sagging nakong ea kaho. Ho phaella moo, e ka eketsa nako ea kaho, ea fa basebetsi nako e eketsehileng ea ho lokisa le ho ntlafatsa boleng ba kaho.

(3) Thibela ho petsoha le ho honyela

The grout e atisa ho honyela le ho petsoha ka lebaka la ho fetoha mouoane ka potlako ha metsi nakong ea ho thatafala. Tšusumetso ea ho boloka metsi ea HPMC e ka fokotsa kotsi ena ka katleho, ea boloka botsitso ba sebopeho sa grout, ea fokotsa tlhahiso ea li-microcracks, le ho ntlafatsa phello ea grouting.

(4) Ntlafatsa thepa e khahlanong le ho sisinyeha

Nakong ea kaho e otlolohileng (joalo ka lebota), sesebelisoa sa caulking se tloaetse ho thella kapa ho thella ka lebaka la matla a khoheli. HPMC e lokisa thepa ea rheological ea caulking agent mme e ntlafatsa thixotropy ea eona, e le hore e boloke viscosity e phahameng sebakeng se tsitsitseng, 'me e tsosolosa metsi nakong ea ts'ebetso ea ho sisinyeha kapa ea kaho, kahoo e fokotsa bothata ba sag le ho ntlafatsa katleho ea kaho.

(5) Ntlafatsa khanyetso ea leqhoa le ho hanyetsa boemo ba leholimo

HPMC e ka ntlafatsa bokhoni ba moemeli oa caulking ho hanela lipotoloho tsa ho qhibiliha, e le hore e lule e tsitsitse maemong a mocheso o tlase 'me ha ho bonolo hore e be phofo kapa e oe. Ka nako e ts'oanang, e ka boela ea ntlafatsa khanyetso ea boemo ba leholimo ea moemeli oa caulking, e le hore e ntse e ka boloka ts'ebetso e ntle tlas'a maemo a thata a kang mongobo le mahlaseli a ultraviolet, le ho lelefatsa bophelo ba eona ba tšebeletso.

4. Lintlha tse amang tšebetso ea HPMC

Liparamente tse joalo ka boima ba limolek'hule tsa HPMC, degree of substitution, le viscosity li tla ama ts'ebetso ea ho qetela ea moemeli oa caulking. Ka kakaretso:
Phahameng viscosity HPMC ka fana ka thickening matla le ho boloka metsi, empa ka fokotsa fluidity;
Tekanyo e nepahetseng ea ho fetola (methoxy le hydroxypropyl content) e ka ntlafatsa ho qhibiliha le ho netefatsa ho tšoana ha moemeli oa caulking;
Tekanyo e nepahetseng e ka ntlafatsa ts'ebetso le ho tšoarella ha moemeli oa caulking, empa tekanyo e feteletseng e ka lebisa ho viscosity e feteletseng, e amang kaho le nts'etsopele ea matla.

E le tlatsetso ea bohlokoa ho li-agent tsa caulking tsa lithaele,HPMChaholo-holo e ntlafatsa boleng ba li-caulking agents ka ho ntlafatsa ho boloka metsi, ho ntlafatsa ts'ebetso ea kaho, le ho matlafatsa khanyetso ea ho honyela le ho tšoarella. Khetho e loketseng ea mefuta le litekanyetso tsa HPMC e ka ntlafatsa ts'ebetso ea li-caulking agents, ea netefatsa kaho e boreleli, 'me ea ntlafatsa litlamorao tsa ho qetela tsa mekhabiso le ts'ireletso. Ka hona, ha ho etsoa moralo oa li-agent tsa lithaelese, khetho le tšebeliso ea HPMC ke tsa bohlokoa.
