Methyl hydroxyethyl cellulose (MHEC) ke motsoako oa bohlokoa oa cellulose ether, o sebelisoang haholo ho thepa ea mohaho, liphahlo, li-ceramics, litlolo le liindasteri tse ling. E le tlatsetso e sebetsang, MHEC e phetha karolo ea bohlokoa mefuteng e fapaneng ea likopo ka lebaka la ho teteka ha eona ho babatsehang, ho boloka metsi, ho khomarela le ho etsa lifilimi.
1. Kopo ka thepa ea mohaho
Ka thepa ea mohaho, MHEC e sebelisoa haholo ka seretse se omeletseng sa samente le se entsoeng ka gypsum, haholo-holo e le setsi se teteaneng, se bolokang metsi le se tlamang. MHEC e ka ntlafatsa haholo ts'ebetso ea kaho ea seretse, ea ntlafatsa ho boloka metsi, le ho thibela ho phatloha ha seretse ho bakoang ke tahlehelo e potlakileng ea metsi. Ho phaella moo, MHEC e ka boela ea ntlafatsa ho khomarela le ho ba le mafura a seretse, ho etsa hore mohaho o be bonolo.
Ka li-adhesives tsa lithaele le li-grouts, ho eketsoa ha MHEC ho ka ntlafatsa ts'ebetso e khahlanong le ho thella ha thepa le ho eketsa nako ea ho bula, ho fa basebetsi ba kaho nako e eketsehileng ea ho lokisa. Ka nako e ts'oanang, MHEC e ka boela ea ntlafatsa ho hanyetsa ho phunyeha le ho hanyetsa shrinkage ea moemeli oa caulking ho netefatsa ts'ebetso ea eona e tsitsitseng ea nako e telele.
2. Kopo indastering ea ho roala
Ka indasteri ea ho roala, MHEC e sebelisoa haholo-holo e le motenya, stabilizer le emulsifier. Hobane MHEC e na le phello e ntle haholo ea ho tenya, e ka laola ka nepo rheology ea ho roala, ka hona e ntlafatsa ts'ebetso le boemo ba ho roala. Ntle le moo, MHEC e ka boela ea ntlafatsa ts'ebetso ea anti-sag ea ho roala le ho netefatsa ho ts'oana le botle ba ho roala.
Lipenteng tsa latex, thepa ea ho boloka metsi ea MHEC e thusa ho thibela ho fetoha mouoane ka potlako ha metsi nakong ea ho omisa, ka hona ho qoba ho hlaha ha bokooa ba holim'a metsi joalo ka mapetsong kapa matheba a omileng. Ka nako e ts'oanang, thepa e ntle ea ho etsa lifilimi ea MHEC e ka boela ea ntlafatsa ho hanyetsa boemo ba leholimo le ho hanyetsa ho senya ha seaparo, ho etsa hore seaparo se be se tšoarellang haholoanyane.
3. Kopo indastering ea ceramic
Ka indasteri ea ceramic, MHEC e sebelisoa haholo e le thuso ea ho bōpa le ho kopanya. Ka lebaka la thepa ea eona e babatsehang ea ho boloka metsi le ho teteaneng, MHEC e ka ntlafatsa ka katleho polasetiki le sebōpeho sa 'mele oa ceramic, ho etsa hore sehlahisoa se be se ts'oanang le se teteaneng. Ho phaella moo, thepa ea tlamahano ea MHEC e thusa ho matlafatsa matla a 'mele o motala le ho fokotsa kotsi ea mapetsong nakong ea sintering.
MHEC e boetse e bapala karolo ea bohlokoa ho likhase tsa ceramic. E ke ke ea ntlafatsa feela ho emisoa le botsitso ba glaze, empa hape e ntlafatsa ho boreleli le ho tšoana ha glaze ho netefatsa boleng ba holim'a lihlahisoa tsa ceramic.
4. Likopo ho litlolo le lihlahisoa tsa tlhokomelo ea botho
MHEC e boetse e sebelisoa haholo ho litlolo le lihlahisoa tsa tlhokomelo ea botho, haholo-holo e le li-thickeners, emulsifiers, stabilizers le li-agents tsa ho etsa lifilimi. Ka lebaka la ho ba bonolo le ho se tenehe, MHEC e loketse ka ho khetheha ho sebelisoa lihlahisoa tsa tlhokomelo ea letlalo tse kang litlolo, litlolo le litlolo tse hloekisang sefahleho. E ka eketsa ka katleho ho tsitsa ha sehlahisoa le ho ntlafatsa sebopeho sa eona, ho etsa hore sehlahisoa se be bonolo le ho se sebelisa habonolo.
Ka lihlahisoa tsa tlhokomelo ea moriri, thepa ea ho etsa filimi ea MHEC e thusa ho theha filimi e sireletsang holim'a moriri, ho fokotsa tšenyo ea moriri ha ho ntse ho fa moriri hore o be bonolo le o bonolo. Ho phaella moo, thepa ea mongobo ea MHEC e ka boela ea phetha karolo ea ho koala ka metsing le ho nosetsa lihlahisoa tsa tlhokomelo ea letlalo, ho atolosa phello ea mongobo.
5. Likopo liindastering tse ling
Ho phaella libakeng tse ka sehloohong tsa kopo tse boletsoeng ka holimo, MHEC e boetse e phetha karolo ea bohlokoa liindastering tse ling tse ngata. Ka mohlala, indastering ea ho phunya oli, MHEC e sebelisetsoa ho cheka metsi e le ho teteaneng le ho tsitsisa ho ntlafatsa rheology ea mokelikeli oa ho phunya le bokhoni ba eona ba ho jara li-cuttings. Lefapheng la masela, MHEC e sebelisoa e le motenya bakeng sa pente ea khatiso, e ka ntlafatsang ho hlaka le ho khanya ha mebala ea mekhoa e hatisitsoeng.
MHEC e boetse e sebelisoa indastering ea meriana e le setsi sa ho kopanya le ho etsa lifilimi bakeng sa matlapa, a ka ntlafatsang matla a mochine le boleng ba ponahalo ea matlapa. Ho phaella moo, indastering ea lijo, MHEC e boetse e sebelisoa e le motenya le emulsifier ha ho etsoa li-seasoning, lino le lihlahisoa tsa lebese ho ntlafatsa tatso le botsitso ba sehlahisoa.
Methylhydroxyethylcellulose (MHEC) e 'nile ea sebelisoa haholo ka thepa ea mohaho, liphahlo, li-ceramics, litlolo le liindasteri tse ling ka lebaka la ho teteka ha eona, ho boloka metsi, ho khomarela le ho etsa lifilimi. Ka tsoelo-pele e tsoelang pele ea theknoloji le mefuta-futa ea litlhoko tsa 'maraka, masimo a kopo a MHEC a ntse a hola,' me bohlokoa ba eona liindastering tse fapaneng bo tla hlahella le ho feta.
