Skim Coat ke Eng?

Skim coat ke lesela le tšesaane la thepa e kentsoeng leboteng kapa siling ho thethefatsa mefokolo le ho etsa sebaka se bataletseng bakeng sa ho penta kapa ho etsa wallpaper. Thepa e sebelisoang bakeng sa ho roala skim hangata ke motsoako oa metsi, samente le lisebelisoa tse ling tse kang cellulose ether.

Cellulose ether ke polima e qhibilihang ka metsing e tsoang ho selulose ea tlhaho. E sebelisoa haholo indastering ea kaho e le setsi sa motenya, se tsitsitseng, se kopanyang le ho boloka metsi. Tabeng ea seaparo sa skim, cellulose ether e kenngoa motsoako ho fana ka ts'ebetso e ntlafetseng ea ho sebetsa le ho boloka metsi.

E 'ngoe ea likarolo tsa bohlokoa tsa cellulose ether ka skim coat ke bokhoni ba eona ba ho tiisa motsoako. Skim coat e hloka ho ba tšesaane ka ho lekaneng hore e ka hasana habonolo holim'a metsi empa e le e lekaneng ho tlatsa likheo kapa ho se phethahale. Cellulose ether e thusa ho finyella ho lumellana ho nepahetseng ka ho tiisa motsoako, ho etsa hore ho be bonolo ho hasana ka mokhoa o tšoanang holim'a metsi.

Mosebetsi o mong oa bohlokoa oa cellulose ether ka skim coat ke bokhoni ba eona ba ho boloka metsi. Skim coat e hloka ho lula e le mongobo ka nako e itseng ho netefatsa hore e khomarela hantle le ho thibela ho phunyeha kapa ho fokotseha. Cellulose ether e thusa ho boloka metsi ka har'a motsoako, e leng ho fokotsang mokhoa oa ho omisa le ho etsa bonnete ba hore seaparo sa skim se beha hantle.

Cellulose ether e boetse e sebetsa e le setlamo sa seaparo sa skim, se thusang ho tšoara motsoako hammoho le ho ntlafatsa ho khomarela holimo. Sena se etsa bonnete ba hore seaparo sa skim se theha maqhama a matla le bokaholimo, ho etsa hore ho be le boreleli le bokaholimo bakeng sa ho penta kapa ho etsa wallpaper.

Boleng le ts'ebetso ea skim coat li susumetsoa haholo ke mofuta le bongata ba cellulose ether e sebelisoang. Ho na le mefuta e fapaneng ea cellulose ether e fumanehang 'marakeng, joalo ka hydroxyethyl cellulose (HEC), methyl cellulose (MC), le carboxymethyl cellulose (CMC). Mofuta o mong le o mong o na le thepa le litšoaneleho tse fapaneng, 'me ho bohlokoa ho khetha mofuta le palo e nepahetseng ho khethollang boleng ba seaparo sa skim.

Ka kakaretso, cellulose ether e bapala karolo ea bohlokoa tlhahisong ea skim coat. E fana ka thepa e hlokahalang ea ho tiisa, ho tlama le ho boloka metsi ho motsoako, o tiisang hore o sebetsa hantle, o ntlafatsa ho khomarela, 'me o thibela ho phunyeha kapa ho fokotseha. Ho khetha mofuta o nepahetseng le palo ea cellulose ether ke ea bohlokoa ho hlahiseng seaparo sa boleng bo phahameng sa skim se finyellang litekanyetso tse lakatsehang tsa indasteri ea kaho.
