Hobaneng lipolyme tsa HPMC li loketse limaraka tsohle tsa likhomaretsi tsa lithaele

Hydroxypropyl methylcellulose (HPMC) polymer e sebelisoa haholo indastering ea kaho e le tlatsetso ea lisebelisoa tse fapaneng tse kenyelletsang likhomaretsi tsa lithaele. Li-polymers tsa HPMC li fana ka melemo e mengata ho limaraka tsohle tsa likhomaretsi tsa lithaele, li li etsa khetho e ntle bakeng sa merero e mengata ea kaho. Sengoliloeng sena se tla hlahloba hore na hobaneng lipolyme tsa HPMC li le molemo bakeng sa likhomaretsi tsa lithaele.

1. Ntlafatsa mokhoa oa ho sebetsa

E 'ngoe ea melemo ea mantlha ea lipolymer tsa HPMC ka har'a likhomaretsi tsa lithaele ke hore li thusa ho ntlafatsa ts'ebetso. Likhomaretsi tsa lithaele tse nang le HPMC li na le phallo e ntle le thepa ea ho hasana hantle. Sena se etsa hore sekhomaretsi se be bonolo ho se sebelisa mme se tiisa hore ho kentsoe lithaele hantle. Sekhomaretsi se boetse se na le monyetla o fokolang oa ho kopanya le ho kopanya, tse ka amang boleng ba sehlahisoa se felileng.

2. Ho boloka metsi ho molemo

Monyetla o mong oa bohlokoa oa lipolymer tsa HPMC ka har'a likhomaretsi tsa lithaele ke thepa ea tsona e ntle ea ho boloka metsi. HPMC e ka ts'oara boima ba eona ka makhetlo a ts'eletseng ka metsing, e leng bohlokoa bakeng sa likhomaretsi tse sebelisoang libakeng tse mongobo joalo ka likamore tsa ho hlapela, kichine le matamo a ho sesa. Sekhomaretsi sa lithaele se nang le thepa e ntle ea ho boloka metsi se tiisa hore sekhomaretsi se omella butle-butle, se fa motho ea kenyang nako ea ho lokisa le ho hokahanya lithaele pele sekhomaretsi se beha.

3. Lintho tsa ho khomarela

Sekhomaretsi sa lithaele se tlameha ho khomarela ka bobeli substrate le tile. Thepa ea sekhomaretsi ea HPMC polymer e thusa sekhomaretsi hore se khomarele hantle libakeng tseo ka bobeli. Li-polymers tsa HPMC li eketsa momahano oa sekhomaretsi, ho bolelang hore sekhomaretsi se ke ke sa ebola hole le substrate kapa tile, leha e le tlas'a khatello.

4. Eketsa ho tenyetseha

Likhomaretsi tsa lithaele tse nang le lipolima tsa HPMC tse kenyellelitsoeng li tenyetseha ho feta likhomaretsi tsa lithaele ntle le lipolima tsa HPMC. Sena se eketsehile ho feto-fetoha ha maemo ho tiisa hore sekhomaretsi se ka mamella khatello ea maikutlo ea ho sisinyeha ntle le ho senya kapa ho senya. Sekhomaretsi se amohela katoloso ea mocheso, ho lula le ho sisinyeha ho ka hlahang meahong. Ho feto-fetoha ha maemo hona ho etsa hore HPMC e be khetho e ntle bakeng sa likhomaretsi tse sebelisoang libakeng tse nang le sephethephethe se phahameng moo sephethephethe sa maoto sa kamehla se ka behang khatello holim'a lithaele.

5. Fokotsa ho fokotseha

Likhomaretsi tsa lithaele tse nang le lipolymer tsa HPMC le tsona li honyela hanyane nakong ea ho omisoa. Lintho tse fokolang li ka baka mathata a ho kenya le ho ama ponahalo ea kakaretso ea morero. Ka ho fokotsa shrinkage, sekhomaretsi se boloka molumo oa sona le sebōpeho sa sona, se etsa hore ho kenngoa ha lithaele ho be bonolo le ho potlaka.

6. Ts'ebetso e phahameng ea litšenyehelo

Li-polymers tsa HPMC li na le chelete e ngata hobane li fokotsa bongata ba lisebelisoa tse ling tse turang tse hlokahalang mekhoeng ea sekhomaretsi sa lithaele. Li-polymers tsa HPMC li thusa ho theha likhomaretsi tsa boleng bo holimo le ho ntlafatsa ts'ebetso ea sekhomaretsi ka kakaretso. Tšebeliso ea polymer ea HPMC e boetse e fokotsa nako ea ho folisa ea sekhomaretsi, ka hona e fokotsa nako ea ho kenya.

7. Tšireletso ea tikoloho

HPMC polymer e na le botsoalle ba tikoloho ebile e khona ho bola. Ha li na lik'hemik'hale tse kotsi kapa chefo, e leng se etsang hore e be khetho e sireletsehileng bakeng sa li-adhesives tsa lithaele. Ho feta moo, li-polymers tsa HPMC li entsoe ka lisebelisoa tse nchafalitsoeng, ka hona, ho li sebelisa ka har'a likhomaretsi tsa lithaele ho thusa ho fokotsa tšusumetso ea tikoloho mererong ea kaho.

ha re phethela

Li-polymers tsa HPMC li loketse limaraka tsohle tsa likhomaretsi tsa lithaele. Ba ntlafatsa ho sebetsa, ho boloka metsi, ho khomarela, ho tenyetseha le ho fokotsa ho fokotseha. Li-polymer tsa HPMC le tsona li na le litšenyehelo tse tlase ebile li na le botsoalle ba tikoloho. Likhomaretsi tsa lithaele tse sebelisang lipolymer tsa HPMC li fa likonteraka, lihahi esita le li-DIYers khetho e ntle. Ka ho sebelisa likhomaretsi tsa lithaele tse nang le lipolymer tsa HPMC, u ka etsa bonnete ba hore ho kenya lithaele tsa hau ke tsa boleng bo holimo, ho tenyetseha ebile ho tšoarella nako e telele.
