tsebisa:
Methylhydroxyethylcellulose (MHEC) ke ether ea selulose e sebetsang ka bongata e sebelisoang haholo liindastering tse fapaneng ka lebaka la ho boloka metsi hantle le thepa ea sekhomaretsi.MHEC e tsoa ho cellulose ea tlhaho 'me e fumane likopo ho haha, meriana, lijo le litlolo.
Sebopeho sa lik'hemik'hale le thepa:
MHEC ke methyl-substituted hydroxyethylcellulose derivative e nang le sebopeho se ikhethang sa limolek'hule.Mokokotlo oa cellulose o fana ka biodegradability ea tlhaho le ho lumellana ha tikoloho, ho etsa hore MHEC e be khetho ea pele bakeng sa lits'ebetso tse ngata.Lihlopha tsa Hydroxyethyl le methyl li ntlafatsa ho qhibiliha ha eona le ho fetola thepa ea eona ea 'mele le lik'hemik'hale, ho e fa mefuta e sa tšoaneng ea mesebetsi.
Mokhoa oa ho boloka metsi:
E 'ngoe ea litšobotsi tsa mantlha tsa MHEC ke bokhoni ba eona bo botle ba ho boloka metsi.Lisebelisoa tsa kaho tse kang seretse le lihlahisoa tsa samente, MHEC e sebetsa e le moemeli oa ho boloka metsi, ho thibela ho lahleheloa ke metsi ka potlako nakong ea ho phekola.Sena se bohlokoa ho boloka ts'ebetso e nepahetseng, ho ntlafatsa ho khomarela le ho ntlafatsa ts'ebetso ea kakaretso ea thepa.
MHEC e fihlella ho boloka metsi ka mekhoa e mengata:
Hydrophilicity: Sebopeho sa hydrophilic sa MHEC se e nolofalletsa ho monya le ho boloka limolek'hule tsa metsi.Mokokotlo oa cellulose, hammoho le lihlopha tsa hydroxyethyl le methyl, li etsa sebopeho se khonang ho boloka metsi ka har'a matrix a sona.
Lintho tsa ho etsa lifilimi: MHEC e ka etsa filimi e tšesaane, e tenyetsehang ha e qhalakane ka metsing.Filimi e sebetsa e le thibelo, e fokotsa mouoane oa metsi le ho fana ka lera le sireletsang ho boloka mongobo ka har'a thepa.
Phello e matla: Kaha MHEC e ruruha ka metsing, e bontša phello e teteaneng.Viscosity ena e ntseng e eketseha e thusa ho boloka metsi hantle, ho thibela metsi ho arohana le thepa le ho boloka motsoako oa homogeneous.
Likopo tse ntseng li etsoa:
Indasteri ea kaho e itšetlehile haholo ka MHEC bakeng sa thepa ea eona ea ho boloka metsi.MHEC e ruisa seretse, grout le lisebelisoa tse ling tsa samente ka ho ntlafatsa ts'ebetso, ho fokotsa ho phunyeha le ho ntlafatsa ho khomarela.Ho feta moo, MHEC e thusa ho pompa le ho fafatsa thepa ea moaho, e leng se etsang hore e be tlatsetso ea bohlokoa mekhoeng ea sejoale-joale ea kaho.
Lintho tse khomarelang:
Ntle le ho boloka metsi, MHEC e phetha karolo ea bohlokoa ho ntlafatsa ho khomarela likopo tse fapaneng.Lintho tsa eona tsa sekhomaretsi li bohlokoa haholo liindastering tse latelang:
Li-Adhesives tsa Lithaele: MHEC e atisa ho sebelisoa ka li-adhesives tsa lithaele ho matlafatsa matla a maqhama pakeng tsa tile le substrate.E etsa lifilimi tse feto-fetohang le ho ntlafatsa ts'ebetso, ho netefatsa tlamahano e matla le e tšoarellang nako e telele.
Pasting ea Wallpaper: Ha ho etsoa ho peista Wallpaper, MHEC e thusa ho kopanya Wallpaper leboteng.E thibela paste hore e se ke ea omella pele ho nako 'me e khothalletsa maqhama a matla le a nako e telele.
Metsoako e Kopanetsoeng: MHEC e sebelisoa ka metsoako e kopanetsoeng ka lebaka la thepa ea eona e tlamang le e teteaneng.E thusa ho fihlela pheletso e boreleli le e khomarelang lits'ebetsong tsa drywall.
ha re phethela:
Methylhydroxyethylcellulose (MHEC) ke ether ea selulose e nang le mahlakore a mabeli e nang le lisebelisoa tse ntle tsa ho boloka metsi le sekhomaretsi.Sebopeho sa eona se ikhethang sa limolek'hule, hydrophilicity, bokhoni ba ho etsa lifilimi le phello e teteaneng e etsa hore e sebelisoe haholo liindastering tse sa tšoaneng.Ho tloha ho thepa ea mohaho ho ea ho meriana le litlolo, MHEC e phetha karolo ea bohlokoa ho ntlafatsa ts'ebetso ea lihlahisoa le ho netefatsa ts'ebetso e nepahetseng.Ha liindasteri li ntse li tsoela pele ho batla tharollo ea tikoloho le e sebetsang hantle, MHEC e ntse e tsoela pele ho ba khetho ea bohlokoa le e tsitsitseng bakeng sa mefuta e fapaneng ea likopo.
