⑵ Ntlafatsa lubricity le polasetiki, 'me u ntlafatse kaho; seretse se ntlafalitsoeng ke cellulose ether se bonolo ho hahoa, se boloka nako ea kaho le ho fokotsa litšenyehelo tsa kaho.
⑶ Ether ea cellulose e bolokang metsi haholo, e loketseng litene tse monyang metsi haholo.
4. Panel joint filler
⑴Ho boloka metsi hantle, ho lelefatsa nako ea ho bula le ho ntlafatsa katleho ea mosebetsi. Lubricant e phahameng, ho bonolo ho e kopanya. ⑵ Ntlafatsa khanyetso ea shrinkage le ho hanyetsa mapheo, ntlafatsa boleng ba bokaholimo. ⑶ Ntlafatsa ho khomarela ha bokaholimo ba tlamahano 'me u fane ka sebopeho se boreleli le se boreleli.
5. Sekhomaretsi sa Lithaele ⑴Ho bonolo ho omisa metsoako e tsoakiloeng, ha ho na makukuno, 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. Lisebelisoa tsa fatše tse ikemetseng ⑴ li fana ka viscosity 'me li ka sebelisoa e le li-addimentation tse thibelang mobu. 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 thehiloeng metsing ⑴Thibela pula e matla 'me u lelefatse bophelo ba sehlahiswa. 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 powder ⑴ Qhibiliha ka potlako ntle le likotola, e leng molemo bakeng sa ho kopanya. ⑵ fana ka matla a phahameng a tlamo.
9. Boto ea samente e fetisitsoeng (1) e na le momahano e phahameng le lubricity, 'me e ntlafatsa machinability ea lihlahisoa tse extruded. ⑵ Ntlafatsa matla a matala, ho khothaletsa hydration le phello ea ho folisa, le ho eketsa chai.
10. Lihlahisoa tsa HPMC tse inehetseng ho lihlahisoa tsa HPMC tse entsoeng ka seretse se entsoeng ka seretse se seng se tsoakiloeng li na le ho boloka metsi ka har'a seretse se seng se tsoakiloeng ho feta lihlahisoa tse tloaelehileng, ho netefatsa hore ho na le metsi a lekaneng a lisebelisoa tsa cementitious, ho thibela haholo ho fokotseha ha matla a tlamahano a bakoang ke ho omisa ho feteletseng. , le Mapetso a bakoang ke ho omisa ho honyela. 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 ea seretse se seng se lokisitsoe le ho fokotsa bothata ba ho haha.
