Methyl Hydroxyethyl Cellulose (MHEC) ke sekhomaretsi se teteaneng le sekhomaretsi se sebelisoang hangata ho thepa ea moaho. Kenyelletso ea eona e na le tšusumetso e kholo ho thepa ea matrix ea samente.
1. Ntlafatsa metsi le ho sebetsa
Methyl hydroxyethyl cellulose, joalo ka motenya, e ka ntlafatsa haholo metsi a matrix a samente. E etsa hore seretse sa samente se be se tsitsitseng le se metsi nakong ea kaho ka ho eketsa viscosity ea motsoako. Sena se thusa ho tlatsa hlobo e rarahaneng le ho fokotsa spatter nakong ea kaho. Ho feta moo, methyl hydroxyethyl cellulose e ka boela ea ntlafatsa ho boloka metsi a matrix a samente le ho fokotsa ts'ebetso ea mali ea slurry ea samente, kahoo e ntlafatsa boleng ba mohaho.
2. Ntlafatsa ho khomarela
Methyl hydroxyethyl cellulose e ka ntlafatsa haholo thepa ea tlamahano ea matrix ea samente. Lebaka ke hobane e na le thepa e ntle ea sekhomaretsi 'me e ka kopana le mongobo ka samenteng ho etsa colloid e nang le sekhomaretsi se matla. Phello ena ea phetoho e bohlokoa haholo bakeng sa ho ntlafatsa sekhomaretsi pakeng tsa matrix a samente le substrate, haholo-holo ho rala lebota, ho peista lithaele tsa ceramic le lits'ebetso tse ling.
3. E ama matla le ho tšoarella
Ho eketsoa ha methylhydroxyethylcellulose ho na le tšusumetso e itseng ho matla a matrix a samente. Ka har'a mefuta e itseng ea litekanyetso, methylhydroxyethyl cellulose e ka ntlafatsa matla a khatello le matla a flexural a matrix a samente. Ka ho ntlafatsa ho ts'oana le botsitso ba pente ea samente, e fokotsa li-pores le mapetsong a matrix a samente, kahoo e matlafatsa matla a kakaretso le ho tšoarella ha thepa. Leha ho le joalo, haeba ho eketsoa ho hongata haholo, ho ka 'na ha fella ka ho fokotseha ha maqhama pakeng tsa samente le kakaretso ea matrix ea samente, kahoo e ama matla a eona a ho qetela.
4. Ntlafatsa ho hanyetsa mapheo a matrix a samente
Kaha methylhydroxyethylcellulose e ka ntlafatsa ho boloka metsi a matrix a samente, e ka fokotsa mapetsong a bakoang ke ho omisa ho isa tekanyong e itseng. Ho omisa shrinkage ea matrix ea samente ke e 'ngoe ea lisosa tse ka sehloohong tsa ho phatloha,' me methylhydroxyethyl cellulose e thusa ho fokotsa kotsi ea mapetsong a bakoang ke ho omisa shrinkage ka ho fokotsa mouoane o potlakileng oa metsi.
5. Taolo ea bubble ka matrix a samente
Methyl hydroxyethyl cellulose e ka etsa sebopeho sa foam se tsitsitseng ka har'a matrix ea samente, e thusang ho ntlafatsa ho kenngoa ha moea oa matrix a samente. Thepa ena ea taolo ea bubble ea moea e phetha karolo ea ho ntlafatsa thepa ea ho kenya mocheso oa matrix a samente le ho fokotsa bongata ba matrix a samente. Leha ho le joalo, li-bubble tse ngata haholo li ka etsa hore thepa e felloe ke matla, kahoo chelete e loketseng e tlameha ho eketsoa ho latela ts'ebeliso e khethehileng.
6. Ntlafatsa ho se khonehe
Ka ho ntlafatsa ho bolokoa ha metsi a matrix a samente, methylhydroxyethylcellulose e ka fokotsa ka nepo ho kenella ha matrix a samente. Sena ke sa bohlokoa haholo ho ntlafatsa ts'ebetso e sa tsitsang le e sa keneleng metsi ea matrix ea samente, haholo-holo lits'ebetsong tse hlokang ho thibela metsi, joalo ka likamore tse ka tlase, mabota a kantle, joalo-joalo.
Tšebeliso ea methylhydroxyethyl cellulose ka matrix ea samente e ka tlisa lintlafatso tse fapaneng tsa ts'ebetso, ho kenyelletsa ho ntlafatsa metsi, ho ntlafatsa ho khomarela, ho matlafatsa matla, ho ntlafatsa ho hanyetsa ho phatloha, ho laola li-bubble le ho ntlafatsa ho se lekane. Leha ho le joalo, ts'ebeliso le karolo ea eona li hloka ho lokisoa ka mokhoa o utloahalang ho latela litlhoko tse ikhethileng tsa ts'ebeliso le litlhoko tsa lisebelisoa ho fumana liphetho tse ntle ka ho fetisisa tsa ts'ebetso. Ka tlatsetso le boitokisetso ba mahlale le bo loketseng, methyl hydroxyethyl cellulose e ka ntlafatsa ts'ebetso e akaretsang ea matrix ea samente le ho fihlela litlhoko tse fapaneng tsa boenjiniere.
