⑶ Ntlafatsa ho khomarela ha bokaholimo ba tlamahano 'me u fane ka sebopeho se boreleli le se boreleli.
5. Sekhomaretsi sa lithaele
⑴Motsoako o bonolo ho omisa, ha ho kopane, eketsa lebelo la ts'ebeliso, ntlafatsa ts'ebetso ea kaho, boloka nako ea ho sebetsa le ho fokotsa litšenyehelo tsa ho sebetsa.
⑵ Ka ho lelefatsa nako ea ho bula, ho sebetsa hantle ha lithaele ho ka ntlafatsoa mme ho ka fanoa ka phello e ntle ea ho khomarela.
6. Thepa ea ho ikemela fatše
⑴Fana ka viscosity 'me e ka sebelisoa e le setlolo se thibelang sedimentation.
⑵ Ntlafatsa ho pompa ha metsi le ho ntlafatsa ts'ebetso ea ho betla fatše.
⑶ Laola ho bolokoa ha metsi le ho honyela, fokotsa mapetsong le ho honyela ha mobu.
7. Pente e entsoeng ka metsi
⑴Thibela pula e matla le ho lelefatsa bophelo ba setshelo sa sehlahisoa.Botsitso bo phahameng ba likokoana-hloko, ho lumellana ho babatsehang le likarolo tse ling.
⑵ Ntlafatsa mokelikeli, fana ka thepa e ntle ea anti-splash, anti-sagging le boemo bo holimo, 'me u netefatse hore ho felile ka holimo.
8. Wallpaper Phofo
⑴ Qhibiliha ka potlako ntle le likotola, tse molemo bakeng sa ho tsoakoa.
⑵ fana ka matla a phahameng a tlamo.
9. Boto ea samente e atolositsoeng
⑴ E na le momahano e phahameng le mafura, 'me e ntlafatsa ho sebetsa ha lihlahisoa tse fetisitsoeng.
⑵ Ntlafatsa matla a matala, ho khothaletsa hydration le phello ea ho folisa, le ho eketsa chai.
10. Lihlahisoa tsa HPMC bakeng sa seretse se seng se lokiselitsoe
Sehlahisoa sa HPMC se sebelisoang ka ho khetheha bakeng sa seretse se kopantsoeng se na le ho boloka metsi ho feta lihlahisoa tse tloaelehileng ka har'a seretse se tsoakiloeng, se netefatsang metsi a lekaneng a lisebelisoa tsa samente, le ho thibela haholo phokotso ea matla a tlamahano a bakoang ke ho omisa ho feteletseng le ho phunyeha ho bakoang ke ho omisa shrinkage.HPMC e boetse e na le phello e itseng ea ho kenya moea.Sehlahisoa sa HPMC se sebelisoang ka ho khetheha bakeng sa seretse se kopantsoeng se na le palo e loketseng ea li-bubble tsa moea tse koetlisitsoeng, junifomo le tse nyenyane, tse ka ntlafatsang matla le boreleli ba seretse se seng se kopantsoe.Sehlahisoa sa HPMC se sebelisoang ka ho khetheha bakeng sa seretse se kopantsoeng se na le phello e itseng ea ho lieha, e ka lelefatsang nako ea ho bula seretse se seng se lokisitsoe le ho fokotsa bothata ba ho haha.Hydroxypropyl methylcellulose (HPMC) ke ether e seng ionic cellulose e entsoeng ka selulose ea tlhaho ea polymer ka letoto la lits'ebetso tsa lik'hemik'hale.Ke phofo e tšoeu e sa nkheng, e sa latsoeheng le e se nang chefo, e kokomohang hore e be motsoako o hlakileng kapa o nang le maru hanyenyane metsing a batang.E na le ho teteana, ho kopanya, ho qhalakanya, emulsifying, filimi-forming, suspending, adsorbing, gelling, superficial, ho boloka mongobo le ho sireletsa thepa ea colloid.Hydroxypropyl methyl cellulose le methyl cellulose li ka sebelisoa ho haha, indasteri ea pente, resin ea maiketsetso, indasteri ea ceramic, meriana, lijo, masela, temo, lik'hemik'hale tsa letsatsi le letsatsi le liindasteri tse ling.
