Carboxymethyl cellulose CMC, sodium carboxymethyl starch (CMS), theko e batla e le theko e tlase (ho tloha ts'ebetsong ea sehlahisoa ka boeona, CMC e tlase ho feta Fuying HPMC), carboxymethyl cellulose e sebelisoa bakeng sa phofo ea putty ea boemo bo tlase bakeng sa marako a kahare Har'a bona. , ho boloka metsi le botsitso li mpe haholo ho feta tsa hydroxypropyl methylcellulose, kahoo e ke ke ea sebelisoa ka putty e sa keneleng metsi le e ka ntle ea mocheso oa mocheso oa motsoako o omileng.
Batho ba bangata ba nahana hore li-cellulose tsena li na le alkaline, 'me samente le lime calcium phofo le tsona ke alkaline,' me ba nahana hore li ka sebelisoa ha li kopane, empa carboxymethyl cellulose le sodium carboxymethyl starch ha se likarolo tse le 'ngoe,' me chloroacetic acid e sebelisoang mosebetsing oa bona oa tlhahiso. E na le asiti, 'me lintho tse setseng nakong ea tlhahiso ea selulose li itšoara ka samente le phofo ea lime calcium, kahoo li ke ke tsa kopanngoa. Baetsi ba bangata ba bile le tahlehelo e kholo ka lebaka la sena, kahoo tlhokomelo e lokela ho lefshoa. Ts'ebeliso ea carboxymethyl cellulose le hydroxypropyl methyl cellulose li ts'oana feela, empa mesebetsi ea tsona e fapane haholo, 'me matšoao a tekheniki a tse peli a arohane haholo. Lisebelisoa tse ka sehloohong tsa tse peli ke k'hothone e hloekisitsoeng e tšoanang, empa lisebelisoa tsa bona tse thusang, lisebelisoa tsa tlhahiso, le phallo ea ts'ebetso li fapane. Thepa ea tlhahiso le ts'ebetso ea hydroxypropyl methylcellulose li rarahane haholo. Tse peli ha se ts'ebetso ea tlhahiso ho hang, 'me lisebelisoa tse ling le tsona li fapane, kahoo litšebeliso le tsona li fapane. Li ke ke tsa nkeloa sebaka, leha e le hore li ka kopanngoa le tse ling ho fokotsa litšenyehelo.
Hydroxypropyl methylcellulose (hpmc) e na le lisebelisoa tse tsitsitseng tsa lik'hemik'hale, ho hanyetsa hlobo, ho boloka metsi ka ho fetisisa le phello e boima, 'me ha e amehe ke liphetoho tsa pH. The viscosity ea 100,000 e loketse putty powder, 'me viscosity ea 150,000 ho 200,000 e loketse putty powder. Ka seretse, haholo-holo e eketsa thepa e lekanyang le ho aha, 'me e ka fokotsa bongata ba samente.
Mosebetsi ke hore seretse sa samente se na le nako ea ho tiisa, 'me se hloka ho bolokoa nakong ea ho tiisa,' me se hloka ho fanoa ka metsi ho boloka mongobo. Ka lebaka la phello ea ho boloka metsi ea selulose, metsi a hlokahalang bakeng sa ho tiisa seretse sa samente a tiisitsoe ho tloha ho boloka metsi a selulose, kahoo phello ea ho tiisa e ka finyelloa ntle le tlhokomelo.
