HPMC (Hydroxypropyl Methylcellulose) ke thepa ea polymer e sebelisoang haholo tšimong ea kaho mme e na le thepa e ikhethang ea 'mele le ea lik'hemik'hale. HPMC e atisa ho sebelisoa e le tlatsetso indastering ea kaho ho ntlafatsa thepa ea thepa ea mohaho, haholo-holo ka seretse, putty powders, likoahelo le lihlahisoa tsa samente.
1. Kopo ka seretse
Likamoreng tsa kaho, HPMC e sebelisoa haholo ho ntlafatsa ts'ebetso ea kaho. Metsi a eona a ho boloka metsi, a teteaneng le a anti-sag a etsa hore HPMC e be le karolo ea bohlokoa ho lirekere tse tsoakiloeng, likhomaretsi tsa lithaele tsa ceramic, lirekere tsa masonry le masimo a mang.
Ho boloka metsi: HPMC e ka ntlafatsa haholo matla a ho boloka metsi a seretse le ho thibela metsi hore a se ke a fetoha mouoane ka potlako, kahoo e netefatsa hore samente e na le metsi a lekaneng le ho ntlafatsa matla a ho kopanya le ho hanyetsa seretse. Tšobotsi ena e bohlokoa ka ho khetheha libakeng tsa mocheso o phahameng ho qoba ho phunyeha le ho lahleheloa ke matla ho bakoang ke ho omisa ho feteletseng ha seretse.
Ho teteana: HPMC e ka fetola metsi le viscosity ea seretse, ea etsa hore seretse se be boreleli nakong ea ts'ebetso, 'me ho be bonolo ho se haha. Ka nako e ts'oanang, e ka boela ea ntlafatsa ho ba metsi le ho khomarela seretse ho lisebelisoa tsa motheo, ho etsa bonnete ba hore seretse se ka khomarela ka thata leboteng kapa lisebelisoa tse ling tsa motheo.
Anti-sag: HPMC e ka thibela seretse hore se senyehe kapa se thekesele ha se aha holim'a libaka tse otlolohileng, haholo ha ho etsoa mekhahlelo e metenya. Ts'ebetso ea eona ea tokiso ea viscosity e ka boloka seretse se le hantle nakong ea kaho ea facade mme ho se bonolo ho oela.
2. Kopo ka li-adhesive tsa lithaele tsa ceramic
Har'a likhomaretsi tsa lithaele tsa ceramic, HPMC e sebelisoa haholo ho ntlafatsa ts'ebetso ea tlamahano le ts'ebetso ea kaho ea lithaele tsa ceramic. Mehahong ea sejoale-joale, lithaele tsa ceramic li sebelisoa haholo bakeng sa mokhabiso oa lebota le fatše, ka hona boleng ba sekhomaretsi bo bohlokoa.
Matla a ntlafetseng a tlamahano: HPMC e tiisa karabelo e feletseng ea hydration ea samente ka ho boloka metsi le liphello tse teteaneng, kahoo e ntlafatsa matla a maqhama pakeng tsa sekhomaretsi le lithaelese tsa ceramic le substrate. Sena ha se lelefatse bophelo ba tšebeletso ea lithaele feela, empa hape se li thibela ho oa ka lebaka la ho se lekane ho khomarela.
Lihora tse atolositsoeng tsa ho bula: Nakong ea ho beha lithaele tsa ceramic, basebetsi ba kaho hangata ba hloka nako e lekaneng ea ho fetola boemo ba lithaele tsa ceramic. Ho eketsoa ha HPMC ho ka eketsa nako ea ho bula sekhomaretsi, ho fa basebetsi ba kaho nako e eketsehileng ea ho sebetsa le ho lokisa, ka hona ho ntlafatsa katleho ea kaho.
Thibela ho thella: Ha u beha lithaele tsa ceramic holim'a facade, HPMC e khona ho thibela lithaele tsa ceramic hore li se ke tsa thella le ho boloka botsitso ba tsona nakong ea kaho. Sena ha se fokotse feela bothata ba ho haha, empa hape se ntlafatsa boleng ba mohaho.
3. Kopo ka phofo ea putty
Karolo ea HPMC ka putty powder e boetse ke ea bohlokoa haholo, haholo-holo ho ntlafatsa ho sebetsa, ho boloka metsi le ho hanyetsa ho phatloha ha putty.
Mosebetsi o ntlafetseng: Ho eketsa HPMC ho putty powder ho ka etsa hore kopo ea putty e be bonolo 'me e qobe likhohlo, ho omella le liketsahalo tse ling nakong ea kaho. Ka nako e ts'oanang, metsi le ductility ea putty le tsona li ka ntlafatsoa, ho etsa hore ho be bonolo ho haha.
Ho boloka metsi a ntlafetseng: Ts'ebetso ea ho boloka metsi ea HPMC e ka etsa bonnete ba hore putty e na le metsi ka ho feletseng leboteng, ho qoba mapetsong kapa ho tlosoa ha phofo ka lebaka la ho lahleheloa ke metsi ka potlako. Haholo-holo libakeng tse omeletseng kapa tse nang le mocheso o phahameng, HPMC e ka liehisa mouoane oa metsi ka nepo, e netefatsa hore ho tlamahanngoa hantle ha putty ho substrate.
Ntlafatsa khanyetso ea Crack: Nakong ea ts'ebetso ea ho omisa, putty e ka 'na ea phatloha ka lebaka la tahlehelo e sa lekaneng ea metsi. HPMC, ka mokhoa o ts'oanang oa ho boloka metsi, e lumella putty hore e ome ka mokhoa o ts'oanang, kahoo e fokotsa haholo kotsi ea ho phatloha.
4. Kopo ka ho roala
HPMC e boetse e na le seabo sa ho tiya, ho boloka metsi le ho tsitsisa masela a thehilweng hodima metsi.
Thickening effect: Ka li-coatings, HPMC e sebelisoa haholo-holo ho lokisa viscosity ea ho roala, ho etsa hore seaparo se senyehe haholoanyane nakong ea ho hlatsoa kapa ho fafatsa, 'me se na le boemo bo botle le ho sebetsa hantle. Ka nako e ts'oanang, e ka thibela pente hore e se ke ea theoha le ho netefatsa phello ea ho penta.
Ho boloka metsi: HPMC e ka thibela ho roala mouoane ho tsoa ka potlako haholo nakong ea kaho, e amang boleng ba kaho. Haholo-holo libakeng tse nang le mocheso o phahameng kapa maemo a fokolang a moea, ho boloka metsi a HPMC ho ka ntlafatsa haholo phello ea kaho ea ho roala.
Phello e tsitsitseng: HPMC e ka boela ea ntlafatsa botsitso ba polokelo ea liphahlo, ea thibela delamination le pula ea liphahlo nakong ea polokelo ea nako e telele, le ho boloka ho ts'oana le botsitso ba boleng ba liphahlo.
5. Kopo ka lihlahisoa tsa samente
HPMC e boetse e sebelisoa haholo lihlahisoa tsa samente tsa precast le lisebelisoa tsa fatše tse ikemetseng. E ka ntlafatsa ho hanyetsa ha crack, matla a khatello le boreleli ba bokaholimo ba lihlahisoa tsa samente.
Ho ntlafala ha ho hanyetsa ha crack: Tšusumetso ea ho boloka metsi ea HPMC e tiisa hore samente e ke ke ea phunyeha ka lebaka la ho tsoa ka potlako ha metsi nakong ea ho thatafala, kahoo ho ntlafatsa boleng ba kakaretso le ho tšoarella ha sehlahisoa.
Ntlafatsa boleng ba bokaholimo: HPMC e etsa hore bokaholimo ba lihlahisoa tsa samente bo be boreleli le boreleli, e fokotsa ho hlaha ha lipompong le mapetsong, hape e ntlafatsa ponahalo ea sehlahisoa se felileng.
Ntlafatsa ts'ebetso ea kaho: Ka thepa ea fatše e ikemetseng, phello e teteaneng ea HPMC e ka ntlafatsa ho phalla ha thepa, ho etsa hore mohaho oa fatše o be o ts'oanang le o boreleli, le ho qoba ho lula ho sa tsitsane le ho phunyeha.
6. Lisebelisoa tse ling
Ntle le lits'ebetso tsa mantlha tse kaholimo, HPMC e boetse e phetha karolo ea bohlokoa ho lisebelisuoa tse thibelang metsi, lisebelisoa tsa ho kenya letsoho, li-caulking agents le masimo a mang. Har'a lisebelisoa tse sa keneleng metsi, thepa ea eona ea ho boloka metsi le e teteaneng e ka ntlafatsa ts'ebetso ea kaho le phello ea ho thibela metsi ea thepa; har'a lisebelisoa tsa ho kenya mocheso, HPMC e thusa ho ntlafatsa matla a ho kopanya le botsitso ba thepa.
Tšebeliso e pharaletseng ea HPMC tšimong ea kaho e bakoa ke thepa ea eona e babatsehang ea 'mele le ea lik'hemik'hale. E le tlatsetso ea bohlokoa ea kaho, HPMC e ke ke ea ntlafatsa ho bolokoa ha metsi feela, ho tiea le ho hanyetsa thepa, empa hape e ntlafatsa haholo ts'ebetso ea kaho le boleng ba sehlahisoa se felileng. Kahong ea sejoale-joale, ebang ke seretse, sekhomaretsi sa lithaele, phofo ea putty, likoatipa le lihlahisoa tsa samente, HPMC e bapala karolo e ke keng ea nkeloa sebaka, ho khothaletsa tsoelo-pele ea theknoloji ea thepa ea moaho le ho ntlafatsa katleho ea kaho.
