Methylhydroxyethylcellulose (MHEC) ke cellulose ether e sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa lekala la meaho le kaho.Ka liphahlo tsa meralo, MHEC ke motenya oa bohlokoa o fanang ka thepa e khethehileng ea ho roala, ka hona e ntlafatsa ts'ebetso ea eona.
Selelekela sa Methyl Hydroxyethyl Cellulose (MHEC)
MHEC ke ether e seng ea ionic cellulose e fumanoang ho tloha selulose ea tlhaho ea polymer ka letoto la liphetoho tsa lik'hemik'hale.E tšoauoa ka motsoako o ikhethang oa lihlopha tsa methyl le hydroxyethyl tse khomaretsoeng mokokotlong oa eona oa cellulose.Sebopeho sena sa limolek'hule se fa MHEC ho boloka metsi ka mokhoa o babatsehang, ho tiisa le ho tsitsisa thepa, ho etsa hore e be e loketseng bakeng sa mefuta e fapaneng ea likopo indastering ea kaho.
Likarolo tsa MHEC
1. Lintho tsa Rheological
MHEC e tsejoa ka thepa ea eona e ntle ea rheological, e fana ka viscosity e ntle le litšobotsi tsa phallo bakeng sa ho roala.Phello e matla ke ea bohlokoa ho thibela ho theoha le ho rotha nakong ea kopo le ho netefatsa hore ho na le seaparo se lekaneng le se boreleli.
2. Ho boloka metsi
E 'ngoe ea litšobotsi tsa bohlokoa tsa MHEC ke bokhoni ba eona ba ho boloka metsi.Sena ke sa bohlokoa ka ho khetheha bakeng sa liphahlo tsa meralo kaha li thusa ho lelefatsa nako e bulehileng ea pente, e lumellang boemo bo betere le ho fokotsa monyetla oa ho omisa pele ho nako.
3. Ntlafatsa ho khomarela
MHEC e ntlafatsa ho khomarela ka ho ntlafatsa ho kolobisa holimo, ho etsa bonnete ba hore ho kopana ho molemo pakeng tsa ho roala le substrate.Sena se ntlafatsa ho khomarela, ho tšoarella le ho sebetsa ka kakaretso ho koahela.
4. Ho tsitsa
MHEC e fana ka botsitso ho ho roala, ho thibela litaba tse kang ho rarolla le ho arohana ha mekhahlelo.Sena se tiisa hore ho roala ho boloka ho tšoana ha eona ho pholletsa le bophelo ba sethala le nakong ea tšebeliso.
Tšebeliso ea MHEC ka liphahlo tsa meralo
1. Pente le primer
MHEC e sebelisoa haholo ha ho etsoa lipente le lipente tsa ka hare le tsa ka ntle.Lintho tsa eona tse teteaneng li thusa ho eketsa viscosity ea liphahlo, e leng se hlahisang tšireletso e ntle le ts'ebetso e ntlafetseng ea kopo.Matla a ho tšoara metsi a tiisa hore pente e tla lula e sebelisoa nako e telele.
2. Ho roala ka motsoako
Liaparong tse entsoeng ka masela, MHEC e bapala karolo ea bohlokoa ho finyella sebopeho se lakatsehang.Thepa ea eona ea rheological e thusa ho emisa li-pigment le li-filler ka mokhoa o ts'oanang, e leng se etsang hore se qetelle se entsoe ka mokhoa o ts'oanang.
3. Stucco le Seretse
MHEC e sebelisoa ho li-stucco le mortar formulations ho ntlafatsa ho sebetsa le ho khomarela.Lintho tsa eona tse bolokang metsi li thusa ho lelefatsa nako e bulehileng, e hlahisang ts'ebeliso e ntle le thepa ea ho qetela.
4. Li-sealants le li-Caulks
Liaparo tsa meralo tse kang li-sealants le caulk li rua molemo ho thepa e teteaneng ea MHEC.E thusa ho laola ho tsitsisa ha metsoako ena, ho netefatsa tiiso e nepahetseng le tlamahano.
Melemo ea MHEC ho Mehaho ea Mehaho
1. Ho lumellana le bonngoe
Tšebeliso ea MHEC e etsa bonnete ba hore liphahlo tsa meralo li boloka sebopeho se ts'oanang le sa viscosity, ka hona ho khothaletsa ts'ebeliso le ho koaheloa.
2. Eketsa lihora tsa ho bula
Thepa ea ho boloka metsi ea MHEC e eketsa nako e bulehileng ea pente, e fa baetsi ba lipente le ba li sebelisang nako e eketsehileng bakeng sa kopo e nepahetseng.
3. Ntlafatsa mokhoa oa ho sebetsa
Ka stucco, seretse le liphahlo tse ling tsa meralo, MHEC e ntlafatsa ts'ebetso ea kopo, e nolofaletsa bakopi ho fihlela pheletso eo ba e batlang.
4. Matlafatso ea nako e telele
MHEC e thusa ho ntlafatsa ho tšoarella ka kakaretso ha koae ka ho ntlafatsa ho khomarela le ho thibela mathata a kang ho thella le ho rarolla.
Methylhydroxyethylcellulose (MHEC) ke motenya oa bohlokoa ka har'a liaparo tsa meralo tse nang le thepa ea bohlokoa ea rheology le ho boloka metsi.Tšusumetso ea eona mabapi le ho tsitsa, ho sebetsa le ho tšoarella ho etsa hore e be khetho ea pele ha ho etsoa lipente, li-primers, liaparo tsa ho roala, stucco, liretse, li-sealants le caulk.Ha indasteri ea kaho e ntse e tsoela pele ho fetoha, MHEC e ntse e le karolo ea mekhoa e mengata le ea bohlokoa ho nts'etsopele ea liphahlo tsa meralo tse sebetsang hantle.
