01. Njirimara nke sodium Bowboxyylcellose
Celloxythymythythythythylythylythylythyl Cellulose bụ polymer polyrmer electrolyte. Ogo nke nbanye nke CMC nke sitere na 0.4 ruo 1.2. Dabere na ịdị ọcha, ọdịdị dị ọcha ma ọ bụ nke ọcha.
1. Ọdịnaya nke ihe ngwọta
Viscosity nke cmc A osisi na-abawanye ngwa ngwa na mmụba nke ịta, na ihe ngwọta nwere njiri mara pseudoplastic. Ngwọta na ogo dị ala (DS = 0.4-0.7) na-enwekarị vixotropy, na ụdị viocosity ga-agbanwe mgbe etinyere na a na-etinye ya na ihe ngwọta. Viscosity nke cmc A osisi na-agbaji na mmụba nke mmụba, mmetụta a na-agbanwe agbanwe mgbe ọnọdụ okpomọkụ anaghị agafe 50 Celsius C. Na elu okpomọkụ ruo ogologo oge, cmc ga-emebi. Nke a bụ ihe kpatara ya na-acha ọbara ọbara glaze dị mfe na-acha ọcha na-emebi emebi mgbe ị na-ebi akwụkwọ ahịrị dị mkpa na-agbaze.
CMC eji maka glaze kwesịrị ịhọrọ ngwaahịa na ogo dị elu, ọkachasị glaze.
2. Mmetụta nke uru PH na CMC
Viscosity nke cmc A osisi na-abụ ihe dị mma na sara mbara, ma na-akwụsi ike n'etiti p 7 na 9. Na ph
Uru na-ebelata, na cmc na-atụgharị site na mpempe nnu na mpempe akwụkwọ acid, nke na-egbochi mmiri na mmiri. Mgbe uru plọ a na-erughị 4, ọtụtụ n'ime ụdị nnu na-agbanwe n'ime ụdị acid na preperates. Mgbe pH dị n'okpuru 3, ogo nke dochie anya ihe na-erughị 0,5, ọ nwere ike gbanwee kpamkpam site n'ụdị nnu ahụ. Uru nke mgbanwe zuru oke nke cmc na ogo dị elu nke dochie anya (karịa 0.9) dị n'okpuru 1. Ya mere, nwaa iji cmc na ogo dị elu maka glaze.
3. Mmekọrịta dị n'etiti cmc na eons eyment
Monvavelent metal-sos-soluble mmiri na cmc, nke a gaghị emetụtakwa viccosity, nke ga-emetụtakwa vicositse ọrịa, mana AG + bụ ihe dị iche, nke ga - eme ka ihe ị ga - esi mee. E ji ụbọ akwara ígwè, dị ka Ba2, Fe2 +, PB2 +, SN2 +, wdg. CA2 +, MG2 +, MN2 +, wdg enweghị mmetụta ọ bụla na ihe ngwọta. Eyịm e metal e eji eme ọla n'ụdị cmc, ma ọ bụ na-acha ma ọ bụ gloride enweghị ike mikpuo na cmc.
Enweghi obi abụọ na mmetụta nta nnu nke cmc:
(1) Ọ bụ ihe metụtara ụdị nnu nnu, uru nke ihe ngwọta na ogo nke cmc;
(2) O metụtara usoro agwakọta na usoro CMC na nnu.
CMC nwere ogo dị elu nwere ndabara ka mma na nnu, na nsonaazụ nke ịtinye nnu na cmc ngwọta dị mma karịa nke mmiri.
Cmc dị mma. Ya mere, mgbe ị na-akwadebe glaze osmootics, na-agbaji cmc na mmiri buru ụzọ, wee tinye nnu nnu.
02. Etu ị ga-esi mata CMC n'ahịa
