Tšebeliso ea CMC ka liphahlo
CMC,sodium carboxymethyl cellulose, e na le mefuta e mengata ea lits'ebetso indastering ea ho roala, haholo-holo e sebeletsa e le setsi se teteaneng, se tsitsitseng, le thuso ea ho etsa lifilimi, e bapala karolo ea bohlokoa ho ntlafatsa ts'ebetso ea ho roala. Ka tlase ke tlhahlobo e qaqileng ea lits'ebetso tsa CMC indastering ea ho roala:
1. Thickening Phello
CMC, motsoako oa polymer oa tlhaho o qhibilihang ka metsi, o ka eketsa ka mokhoa o atlehileng ponahalo ea liphahlo le ho laola thepa ea bona ea rheological, ho etsa hore litlolo li be bonolo le ho li sebelisa habonolo. Ka ho laola palo ea CMC e kenyellelitsoeng, motho a ka khona ho fetola ka nepo botsitso ba lipente tsa latex, ka hona a ntlafatsa ts'ebetso ea tsona ea ts'ebeliso, a fokotsa ho rotha, a ntlafatsa ts'ebetso ea kaho, le ho netefatsa hore ho na le pente.
2. Phello e tsitsitseng
Hangata li-pigments le li-fillers li atisa ho lula, e leng se lebisang ho stratification ea ho roala. Ho eketsoa ha CMC ho ka ntlafatsa haholo botsitso ba likhoele, ho thibela ho lokisoa ha li-pigment le li-fillers, le ho boloka liphahlo tse tšoanang le tse tsitsitseng nakong ea polokelo le tšebeliso. Haholo-holo nakong ea polokelo ea nako e telele, phello ea botsitso ea CMC e bohlokoa haholo. Sebopeho sa marang-rang se entsoeng ke CMC se ka thibela ka katleho ho rarolla li-pigments le li-fillers, ho boloka ho hasana le ho tšoana ha liphahlo.
3. Phello ea Thuso ea ho Etsa Lifilimi
CMC e bapala karolo ea tlatsetso tšebetsong ea ho etsa filimi ea ho roala, ho etsa hore seaparo se bopehileng se be bobebe hape se be boreleli kamora ho omisa. Sena ha se ntlafatse feela boleng ba ponahalo ea ho roala, joalo ka ho fokotsa matšoao a borashe le litlamorao tsa lekhapetla la lamunu, empa hape le ho ntlafatsa ho hanyetsa ha koae, ho hanyetsa botsofali le ho hanyetsa metsi, ka hona ho lelefatsa bophelo ba ts'ebeletso ea ho roala.
4. Ts'ebetso ea Tikoloho
Ka keketseho e tsoelang pele ea litlhoko tsa ts'ireletso ea tikoloho, liphahlo tse thehiloeng metsing li fetohile tse ka sehloohong 'marakeng.CMC, e le tlatsetso ea ho roala e sireletsang tikoloho, ha e na lintho tse kotsi 'me e finyella litekanyetso tsa naha tsa tšireletso ea tikoloho. Tšebeliso ea CMC ka li-coatings e ke ke ea fokotsa feela litaba tsa VOCs (li-volatile organic compounds) empa hape e ntlafatsa ts'ebetso ea tikoloho ea liphahlo, ho finyella litlhoko tsa tsoelo-pele e tsitsitseng ea sechaba sa kajeno.
5. Mefuta e mengata e fapaneng ea likopo
CMC ha e loketse feela lipente tse tloaelehileng tsa latex le liphahlo tse thehiloeng metsing empa hape le bakeng sa libaka tse khethehileng tsa ho roala tse kang liphahlo tsa likoloi, liphahlo tsa metsing, liphahlo tsa boemo ba lijo le liphahlo tsa bongaka. Likarolong tsena, CMC e ka ntlafatsa haholo ho tšoarella le ho hanyetsa kutu ea liphahlo, ho netefatsa polokeho le ts'ireletso ea tikoloho ea lihlahisoa.
Ka kakaretso, CMC e na le litebello tse pharalletseng tsa ts'ebeliso le boleng ba bohlokoa ba ts'ebeliso indastering ea liphahlo. Ha e ntlafatse feela ts'ebetso le boleng ba liphahlo empa hape e kopana le litlhoko tsa sechaba sa morao-rao bakeng sa ts'ireletso ea tikoloho le tsoelo-pele e tsitsitseng. Ka nts'etsopele e tsoelang pele ea indasteri ea liphahlo, ntle le pelaelo CMC e tla bapala karolo ea bohlokoa le ho feta 'marakeng o tlang.
