Kedu ihe dị iche n'etiti hydroxypropyl methylcellulose na carboxymethylcellulose

Carboxymethyl cellulose CMC, sodium carboxymethyl starch (CMS), price bụ dịtụ ọnụ ala (site na arụmọrụ nke ngwaahịa n'onwe ya, CMC bụ a ọkwa ala karịa Fuying HPMC), carboxymethyl cellulose na-eji maka ala-ọkwa putty ntụ ntụ maka ime mgbidi n'etiti ha. , Njide mmiri na nkwụsi ike dị nnọọ njọ karịa nke hydroxypropyl methylcellulose, n'ihi ya, a pụghị iji ya mee ihe na ntinye mmiri na-ekpuchi mmiri na ihe mkpuchi ọkụ na-ekpo ọkụ na-ekpo ọkụ.

Ọtụtụ ndị mmadụ na-eche na cellulose ndị a bụ alkaline, na ciment na lime calcium ntụ ntụ bụkwa alkaline, ha na-eche na a pụrụ iji ha mee ihe na ngwakọta, ma carboxymethyl cellulose na sodium carboxymethyl starch abụghị otu ihe, na chloroacetic acid eji na usoro mmepụta ha. Ọ bụ acidic, na ihe ndị fọdụrụ na usoro mmepụta cellulose na-emeghachi omume na ciment na lime calcium ntụ ntụ, n'ihi ya, a pụghị ijikọta ha. Ọtụtụ ndị na-emepụta ihe enwewo nnukwu mfu n'ihi nke a, n'ihi ya, ekwesịrị ịṅa ntị. Ojiji nke carboxymethyl cellulose na hydroxypropyl methyl cellulose bụ naanị otu, ma ọrụ ha dị nnọọ iche, na teknuzu egosi nke abụọ dị nnọọ iche.

Ngwá ọrụ mmepụta na usoro nke hydroxypropyl methylcellulose dị mgbagwoju anya karị. Ha abụọ abụghị usoro mmepụta ihe ọ bụla, na ngwa ndị ọzọ dịkwa iche iche, ya mere eji eme ihe dị iche iche. Enweghị ike dochie ha, ma ọ bụ jikọta ha na ibe ha iji belata ọnụ ahịa.

Hydroxypropyl methylcellulose (hpmc) nwere akụrụngwa kemịkalụ kwụsiri ike, nguzogide mildew, njigide mmiri kachasị mma na mmetụta na-abawanye, yana mgbanwe pH anaghị emetụta ya. Viscosity nke 100,000 kwesịrị ekwesị maka ntụ ntụ ntụ, na viscosity nke 150,000 ruo 200,000 kwesịrị ekwesị maka ntụ ntụ. N'ime ngwa agha, ọ na-abawanye ụbara ihe onwunwe na ịrụ ọrụ, ma nwee ike belata ọnụ ọgụgụ ciment.

Ọrụ ahụ bụ na ngwa ngwa ciment nwere oge siri ike, ọ dịkwa mkpa ka a na-edozi ya n'oge oge siri ike, ọ dịkwa mkpa ka a na-enye ya mmiri iji mee ka ọ dị mmiri. N'ihi mmetụta njide mmiri nke cellulose, mmiri a chọrọ maka ciment mortar solidification na-ekwe nkwa site na njide mmiri nke cellulose, ya mere enwere ike nweta mmetụta siri ike na-enweghị mmezi.
