Hydroxypropyl Methylcellulose (HPMC) le Hydroxyethyl Cellulose (HEC) li sebelisoa hangata ho thepa ea moaho ka lebaka la mesebetsi le thepa ea tsona e fapaneng. Mona ke e meng ea mesebetsi ea bona ea mantlha ea thepa ea moaho:

1. Poloko ea Metsi: HPMC le HEC li sebetsa joalo ka liemeli tsa ho boloka metsi, ho thusa ho thibela tahlehelo e potlakileng ea metsi ho tsoa linthong tse thehiloeng ho samente joalo ka seretse le samente nakong ea ho phekola. Ka ho etsa filimi ho pota-potile likaroloana tsa samente, li fokotsa mouoane oa metsi, e leng se lumellang hore ho be le metsi a nako e telele le ho ntlafatsa matla a ntlafatso.
2. Ntlafatso ea ho sebetsa: HPMC le HEC li ntlafatsa ts'ebetso ea lisebelisoa tse thehiloeng ho samente ka ho eketsa polasetiki ea tsona le ho fokotsa likhohlano lipakeng tsa likaroloana. Sena se ntlafatsa ho ata, ho momahano, le boiketlo ba tšebeliso ea lirekere, li-renders, le likhomaretsi tsa lithaele, ho etsa hore ho be bonolo ho feta le ho feta.
3. Taolo ea Thickening le Rheology: HPMC le HEC li sebetsa e le li-thickeners le rheology modifiers ho thepa ea mohaho, ho lokisa viscosity ea bona le litšobotsi tsa phallo. Ba thusa ho thibela ho rarolla le ho arohana ha metsoako ka ho emisoa, ho netefatsa ho aroloa ho homogeneous le ts'ebetso e tsitsitseng.
4. Khothatso ea ho Adhesion: HPMC le HEC li ntlafatsa ho khomarela lisebelisoa tse thehiloeng ho samente ho li-substrates tse kang konkreite, masonry le lithaele. Ka ho etsa filimi e tšesaane holim'a substrate, ba matlafatsa matla a maqhama le ho tšoarella ha liretse, li-renders, le li-adhesives tsa lithaele, ho fokotsa kotsi ea delamination kapa ho hlōleha.
5. Phokotso ea Shrinkage: HPMC le HEC li thusa ho fokotsa ho fokotseha le ho phunyeha ha thepa e entsoeng ka samente ka ho ntlafatsa botsitso ba tsona le ho fokotsa khatello ea kelello ea ka hare. Ba finyella sena ka ho ntlafatsa phallo ea likaroloana, ho fokotsa tahlehelo ea metsi, le ho laola sekhahla sa ho phalla ha metsi, ho fella ka ho qeta nako e telele le ho khahleha ka mokhoa o motle.
6. Ho beha Taolo ea Nako: HPMC le HEC li ka sebelisoa ho fetola nako ea ho beha thepa e thehiloeng ho samente ka ho fetola tekanyo ea bona le boima ba limolek'hule. Ba fana ka ho feto-fetoha ha kemiso ea kaho le ho lumella taolo e ntlafetseng holim'a ts'ebetso ea ho beha, ho amohela litlhoko tse fapaneng tsa morero le maemo a tikoloho.
7. Ntlafatso ea ho tšoarella nako e telele: HPMC le HEC li kenya letsoho ho tšoarelleng ha nako e telele ha thepa ea moaho ka ho matlafatsa khanyetso ea tsona khahlanong le maemo a tikoloho joalo ka potoloho ea leqhoa, ho kenella ha mongobo le tlhaselo ea lik'hemik'hale. Li thusa ho fokotsa ho phatloha, ho phatloha le ho senyeha, ho lelefatsa bophelo ba litšebeletso tsa merero ea kaho.

Hydroxypropyl Methylcellulose (HPMC) le Hydroxyethyl Cellulose (HEC) li bapala karolo ea bohlokoa ho ntlafatsa ts'ebetso, ho sebetsa, ho khomarela, ho tšoarella, le boleng ba kakaretso ba thepa ea moaho. Lintho tsa bona tse nang le mesebetsi e mengata li etsa hore e be li-additives tsa bohlokoa mefuteng e mengata ea likopo tsa kaho, ho netefatsa katleho le nako e telele ea merero e sa tšoaneng ea kaho.
