Phello ea Cellulose Ether ho Matla a Adhesive a Seretse

Li-cellulose ethers ke li-additives tse nang le mesebetsi e mengata ea thepa ea mohaho, ho kenyelletsa le lirekere, 'me li 'nile tsa sebelisoa indastering ea kajeno ea kaho ka lilemo tse mashome. E fumaneha ka mefuta le limaraka tse ngata, 'me khetho ea cellulose ether e itšetlehile ka kopo e reretsoeng le thepa ea sehlahisoa sa ho qetela.

Ka kakaretso, cellulose ether e ntlafatsa ts'ebetso ea seretse ka ho ntlafatsa ts'ebetso ea eona, ho boloka metsi le ho khomarela substrate. Sehloohong sena, re tla shebana le phello ea li-cellulose ethers ho khomarela seretse, e leng thepa ea bohlokoa ea seretse.

Ho khomarela ke bokhoni ba thepa e le 'ngoe ho khomarela e' ngoe joalo ka substrate eo seretse se kenngoa ho eona. Ho khomarela seretse ho bohlokoa ho ts'ebetsong le ts'ebetsong ea nako e telele ea mehaho ea mohaho. Lintho tse amang ho khomarela seretse li kenyelletsa thepa ea substrate, thepa ea seretse le maemo a tikoloho.

Cellulose ether e ntlafatsa ho khomarela ha seretse ka ho ntlafatsa thepa ea rheological le ea mechine ea seretse. Taba ea pele, li-cellulose ethers li ntlafatsa rheology ea seretse ka ho eketsa ts'ebetso ea tsona le ho fokotsa karohano. Ho sebetsa ho bolela boiketlo boo seretse se kopantsoeng, se behoang le ho phethoa ka sona, ha khethollo e bolela ho arohana ha likarolo tsa seretse nakong ea ho kopanya kapa ho sebetsana. Rheology ea seretse e ntlafatsoa, ​​​​e lumella hore e phalle le ho tlatsa likheo pakeng tsa substrate le seretse bakeng sa ho khomarela hamolemo.

Ea bobeli, li-cellulose ethers li ntlafatsa mekhoa ea mochine ea seretse, joalo ka matla a eona a thata le a hatellang, a bohlokoa bakeng sa ho khomarela seretse ho substrate. Cellulose ether e ntlafatsa thepa ea mochini oa seretse ka ho ntlafatsa metsi a eona, mokhoa oo samente e sebetsang ka har'a seretse ka metsi ho theha mohaho o thata.

Ho ba teng ha cellulose ether seretseng ho liehisa sekhahla sa ho fetoha mouoane ha metsi seretseng, e leng se bakang ts'ebetso e telele ea ho tsamaisa metsi. Ts'ebetso ea nako e telele ea hydration e theha maqhama a pharaletseng, a matla pakeng tsa seretse le substrate bakeng sa ho khomarela hamolemo.

Li-cellulose ether tse sebelisoang liretseng li tla ka mefuta le mefuta e fapaneng, ho kenyelletsa methylcellulose, hydroxyethylcellulose, le hydroxypropylcellulose. Methylcellulose ke mofuta o tloaelehileng ka ho fetisisa 'me o loketse mefuta e fapaneng ea likopo ka lebaka la matla a eona a ho boloka metsi a mangata, mokhoa oa ho sebetsa le ho ntlafatsa ho khomarela. Hydroxyethyl cellulose, ka lehlakoreng le leng, e na le hydrophilic 'me e khona ho monya le ho boloka metsi, kahoo e matlafatsa ts'ebetso ea seretse le ho khomarela karoloana. Hydroxypropyl cellulose e loketse ho tenya le ho ntlafatsa thepa ea rheological ea seretse, kahoo e ntlafatsa ho khomarela.

Ho akaretsa, cellulose ether ke tlatsetso ea bohlokoa indastering ea kaho mme e phetha karolo ea bohlokoa ho ntlafatseng ho khomarela seretse. Ho ba teng ha cellulose ether ka seretse ho ntlafatsa thepa ea eona ea rheological le ea mechine, e leng se etsang hore ho be le ts'ebetso e ntle, ho phalla le ho khomarela substrate. Khetho ea cellulose ether e itšetlehile ka kopo e reretsoeng le thepa e lakatsehang ea sehlahisoa sa ho qetela. Ha u sebelisa cellulose ether ka seretse, litaelo tsa moetsi li tlameha ho lateloa ho finyella liphello tse ntle le ho netefatsa ho tšoarella le ho sebetsa nako e telele ea mohaho oa mohaho.
