Tsepamisa maikutlo ho Cellulose ethers

Tšebeliso ea hydroxyethyl cellulose pente ke efe?

Hydroxyethyl cellulose (HEC) ke motsoako oa bohlokoa o se nang ionic o qhibilihang ka metsing o nang le lisebelisoa tse ngata tse sebelisoang indastering ea pente le ea ho roala.

1. Thickener
Hydroxyethyl cellulose ke setenya se sebetsang haholo. E ka eketsa viscosity ea pente ka ho monya metsi ka har'a tharollo ea metsi ho atolosa le ho etsa tharollo ea colloidal. Sena ha se thuse feela ho thibela pente hore e se ke ea lula nakong ea polokelo le ea lipalangoang, empa e boetse e ntlafatsa thepa ea eona ea ho lekanngoa le ho emisa, ho netefatsa ho tšoana le ho boreleli ha pente ea pente.

2. Taolo ea mali
Hydroxyethyl cellulose e ka fetola thepa ea rheological ea pente, ke hore, e fetola litšobotsi tsa eona tsa phallo ka litekanyetso tse fapaneng tsa ho kuta. E ka boloka pente ka viscosity e itseng e le boemong bo tsitsitseng ho thibela ho sagging; 'me nakong ea ts'ebetso ea kopo, viscosity e tla fokotseha ka ho eketseha ha sekhahla sa ho kuta, se loketseng ho haha. Thepa ena e thusa ho ntlafatsa kaho le katleho ea mosebetsi oa pente.

3. Ho boloka metsi
Hydroxyethyl cellulose e na le pokello e ntle ea metsi. E ka thibela ka katleho ho fetoha mouoane oa metsi ka potlako, kahoo e lelefatsa nako ea ho omisa pente le ho lumella filimi ea pente hore e be le nako e lekaneng ea ho lekana le ho etsoa ha filimi nakong ea ho omisa. Sena ke sa bohlokoa ka ho khetheha bakeng sa lipente tse thehiloeng metsing, kaha ho lahleheloa ke metsi ka potlako ho ka baka mathata a kang likoti le ho phunyeha ha filimi ea pente.

4. Lintho tse tsitsitseng le tse khahlanong le ho rarolla
Meetsong ea pente, haholo litsamaiso tse nang le li-pigments tse tiileng le li-filler, hydroxyethyl cellulose e ka fana ka botsitso bo botle ba ho emisa ka ho teteana. E ka thibela ka katleho sedimentation ea li-pigments le li-fillers, ho etsa bonnete ba hore pente e kopantsoe ka mokhoa o ts'oanang nakong ea polokelo, 'me kahoo e netefatsa hore mmala o tsitsitse le botsitso ba ts'ebetso ea ho roala.

5. Ntlafatsa thepa ea ho etsa lifilimi
Hydroxyethyl cellulose e ka ntlafatsa thepa ea ho etsa lifilimi ea lipente. E ka etsa lesela la filimi e ts'oanang holim'a seaparo, ho ntlafatsa khanya le ho tšoana ha filimi ea pente. Ho phaella moo, hydroxyethyl cellulose e ka boela ea ntlafatsa ho thibela phofshoana le metsi ho thibela filimi ea ho roala, ho eketsa nako ea eona e tšoarellang le ho khabisa thepa.

6. Thepa e se nang tikoloho
Joaloka motenya o seng oa ionic, hydroxyethyl cellulose ha e na litšepe tse boima le li-solvents tse kotsi, 'me e finyella litlhoko tsa tšireletso ea tikoloho. Tšebeliso ea eona ka lipente tse thehiloeng metsing e ka fokotsa litaba tsa metsoako ea lintho tse phelang (VOCs), e thusang ho fokotsa tšilafalo ea tikoloho le kotsi bophelong ba batho.

Tšebeliso ea hydroxyethyl cellulose ka pente ha e ntlafatse feela thepa ea 'mele le ts'ebetso ea kaho ea sehlahisoa, empa hape e kopana le litlhoko tsa ts'ireletso ea tikoloho le polokeho ea indasteri ea kajeno ea ho roala. E le tlatsetso e nang le mesebetsi e mengata, e phetha karolo ea bohlokoa ho rala moralo le ts'ebetsong ea ho sebelisa pente.
