Leshome le metso e robeli, hydroxypropyl methyl cellulose le MC phapang ke efe:
MC ke methylcellulose, e entsoeng ka k'hothone e hloekisitsoeng ka mor'a phekolo ea alkali le methane chloride e le etherification agent ka letoto la liketso ho etsa cellulose ether. Ka kakaretso, tekanyo ea ho fetola ke 1.6-2.0, 'me ho qhibiliha ha likhato tse fapaneng tsa ho fetola ho boetse ho fapane, e leng ea non-ionic cellulose ether.
(1) Ho boloka metsi a methyl cellulose ho ipapisitse le palo ea eona ea tlatsetso, viscosity, botle ba likaroloana le lebelo la ho qhibiliha. Ka kakaretso, haeba palo ea ho eketsa e le khōlō, botle bo nyenyane 'me viscosity e kholo, tekanyo ea ho boloka metsi e phahame. Palo ea ho eketsa e na le tšusumetso e kholo ho tekanyo ea ho boloka metsi, 'me viscosity ha e amane le tekanyo ea ho boloka metsi. Lebelo la ho qhala haholo-holo le ipapisitse le tekanyo ea phetoho ea bokaholimo ba likaroloana tsa cellulose le botle ba likaroloana. Ho selulose e ka holimo ea ether methyl cellulose le hydroxypropyl methyl cellulose sekhahla sa ho boloka metsi se phahame.
(2) Methyl cellulose e ka qhibiliha ka metsing a batang, ho qhibiliha ha metsi a chesang ho tla kopana le mathata, tharollo ea eona e nang le metsi a mangata ka har'a pH = 3-12 e tsitsitse haholo, 'me starch,' me ho lumellana ho hoholo ha surfactant ho molemo, ha mocheso o fihla ho mocheso oa gelation, ketsahalo ea gelation e tla etsahala.
(3) Phetoho ea mocheso e tla ama ka botebo sekhahla sa ho boloka metsi a methyl cellulose, hangata ha mocheso o phahame, ho boloka metsi ho mpefala. Haeba mocheso oa seretse o feta likhato tse 40, ho boloka metsi a methyl cellulose ho tla mpefala haholo, ho ama ka ho teba ho hahoa ha seretse.
(4) Methyl cellulose e na le tšusumetso e totobetseng mohahong le ho khomarela seretse. Mona, sekhomaretsi se bolela matla a sekhomaretsi a utluoang pakeng tsa sesebelisoa sa daub sa basebetsi le substrate ea lebota, ke hore, ho hanyetsa ha seretse. Thepa ea sekhomaretsi e kholo, khanyetso ea ho kuta ea seretse e kholo, 'me matla a hlokoang ke basebetsi ha a ntse a sebelisoa le ona a maholo, kahoo thepa ea kaho ea seretse e futsanehile.
