Ho sebelisa Hydroxypropyl Methylcellulose (HPMC) ka har'a seretse le li-plaster ho fana ka melemo e mengata, e etsang hore e be khetho e tsebahalang lits'ebetsong tsa kaho.Keketso ena e feto-fetohang e ntlafatsa thepa e fapaneng ea seretse le li-plaster, e thusa ho ntlafatsa ts'ebetso, ho khomarela, ho boloka metsi le ho tšoarella.
1. Matla a Ntlafetseng a ho sebetsa: HPMC e sebetsa e le mofetoleli oa rheology, ho ntlafatsa ts'ebetso ea lirafshoa le li-plaster ka ho fana ka mokhoa o tsitsitseng le o momahaneng.E nolofalletsa ho kopanya le ho sebelisa habonolo, ho lumella taolo e ntle nakong ea mesebetsi ea kaho.Likonteraka li rua molemo litšenyehelong tse fokotsehileng tsa basebetsi le tlhahiso e eketsehileng ka lebaka la ts'ebetso e ntlafetseng e tsamaisoang ke HPMC.
2. Keketseho ea Paballo ea Metsi: E 'ngoe ea melemo ea bohlokoa ea ho sebelisa HPMC ke bokhoni ba eona ba ho boloka metsi ka har'a seretse kapa samente.Ho boloka metsi ka nako e telele ho etsa bonnete ba hore ho na le metsi a lekaneng a lisebelisoa tsa samente, ho khothalletsa ntlafatso e nepahetseng ea matla le ho fokotsa kotsi ea ho omisoa pele ho nako.Ka lebaka leo, lirafshoa le li-plaster tse nang le HPMC li bonts'a maqhama a ntlafetseng ho li-substrates le ho fokotsa ho phunyeha ha shrinkage.
3. Ntlafatso ea Khomaretso: HPMC e ntlafatsa thepa ea sekhomaretsi ea seretse le li-plaster, e nolofalletsang ho tlamahanngoa ho molemo ho likaroloana tse fapaneng tse kang konkreite, masonry le lehong.Khomaretsi e ntlafalitsoeng e thusa ho thibela delamination mme e netefatsa ho tšoarella ha nako e telele ea pheletso e sebelisitsoeng.Sena se molemo haholo lits'ebetsong tsa ka ntle moo ho pepesehela maemo a leholimo a mabe ho hloka ho khomarela ka matla.
4.

5. Crack Resistance: Ho kenyelletsa HPMC ka har'a seretse le li-plaster ho matlafatsa ho hanyetsa ha tsona ho phunyeha, kahoo ho ntlafatsa ho tšoarella ha kakaretso ea sebopeho.Ho boloka metsi ho laoloang ke HPMC ho fokotsa monyetla oa ho phatloha ha polasetiki nakong ea mehato ea pele ea ho folisa.Ho feta moo, mofuta o momahaneng oa metsoako e fetotsoeng ea HPMC e thusa ho aba likhatello ka mokhoa o atlehileng haholoanyane, ho fokotsa sebopeho sa mapetsong a moriri ka nako.
6. Tšireletseho e Ntlafetseng ea Sebaka sa Mosebetsi: HPMC e thusa ho fokotsa ho hlahisa lerōle nakong ea ho kopanya le ho sebelisoa ha seretse le li-plaster, ho kenya letsoho tikolohong e sireletsehileng ea sebaka sa mosebetsi.Likonteraka le basebetsi ba kaho ba rua molemo ka ho fokolloa ke ho pepesehela likaroloana tse tsamaisoang ke moea, e leng se lebisang ho ntlafatso ea bophelo bo botle ba ho hema le bophelo bo botle ka kakaretso.Ho feta moo, ts'ebetso e ntlafalitsoeng e tsamaisoang ke HPMC e fokotsa tlhoko ea ho ts'oaroa ka mokhoa o feteletseng, ho fokotsa kotsi ea likotsi tsa mesifa le masapo.
7. Ho lumellana le Li-additives: HPMC e bonts'a tšebelisano e ntle haholo le li-additives tse fapa-fapaneng tse atisang ho sebelisoa mefuteng ea seretse le samente, tse kang li-air-entraining agents, li-plasticizers le li-mineral admixtures.Tšebelisano ena e lumella ho hlophisoa ha thepa ea seretse le samente hore e finyelle litlhoko tse khethehileng tsa ts'ebetso, joalo ka mokhoa o ntlafalitsoeng oa ho hanyetsa serame, ho kenella ha metsi, kapa ho sebetsa ho matla ha mocheso o feteletseng.
8. Ho feto-fetoha ha maemo: HPMC e ka sebelisoa mefuteng e mengata ea libopeho tsa seretse le samente, ho kenyeletsoa litsamaiso tse thehiloeng ho samente, tse entsoeng ka lime, le tsa gypsum.Ho feto-fetoha ha eona ho etsa hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng tsa kaho, ho kenyelletsa ho aha litene, ho li fetolela, ho kenya lithaele le ho lipola.Likonteraka le li-specifiers li na le monyetla oa ho kenyelletsa HPMC ka har'a metsoako e fapaneng ntle le ho senya ts'ebetso, ka tsela eo ba nolofatsa theko ea thepa le taolo ea thepa.
