Kedu ihe bụ viscosity nke hydroxyethyl cellulose?

Hydroxyethylcellulose (HEC) bụ nonionic, mmiri na-soluble polima nke sitere na cellulose. N'ihi njirimara rheological ya pụrụ iche, a na-ejikarị ya na ụlọ ọrụ dị iche iche gụnyere ọgwụ, ihe ịchọ mma na ihe owuwu. Otu n'ime ihe ndị bụ isi nke hydroxyethyl cellulose bụ viscosity ya, nke na-arụ ọrụ dị mkpa n'ịchọpụta ọrụ ya na ngwa dị iche iche.

Viscosity bụ ihe nleba anya nke mmiri na-eguzogide ịgbasa. N'ihe banyere hydroxyethylcellulose, viscosity ya na-emetụta ọtụtụ ihe, gụnyere itinye uche, okpomọkụ na ọnụ ọgụgụ shear. Ịghọta ihe ndị a dị oke mkpa iji kwalite ojiji nke HEC na usoro dị iche iche.

Viscosity nke hydroxyethylcellulose siri ike dabere na ntinye ya na ngwọta. N'ozuzu, ka ntinye uche HEC na-abawanye, viscosity ya na-abawanye. Omume a bụ ụdị ngwọta polymer ma na-akọwakarị ya site n'ụdị iwu ike nke metụtara viscosity na itinye uche.

Okpomọkụ na-enwekwa mmetụta dị ukwuu na viscosity nke ngwọta hydroxyethyl cellulose. N'ọtụtụ ọnọdụ, viscosity na-ebelata na okpomọkụ na-abawanye. Mmetụta okpomọkụ a dị oke mkpa maka ngwa ebe ihe dị mkpa iji mee mgbanwe na viscosity, dị ka n'oge nrụpụta ma ọ bụ mgbe etinyere ya n'elu dị iche iche.

Ọnụọgụ shear bụ ihe ọzọ dị mkpa na-emetụta viscosity nke hydroxyethyl cellulose. Ọnụọgụ shear na-ezo aka na ọnụego nke ọkwa mmiri dị n'akụkụ na-agagharị na ibe ha. Viscosity nke ngwọta HEC na-egosipụtakarị omume ịhịa aka n'ahụ, nke pụtara na ka ọnụ ọgụgụ shear na-abawanye, viscosity na-ebelata. Ngwongwo a bara uru na ngwa dị ka mkpuchi na adhesives ebe ọ dị mfe ngwa ngwa.

Arọ molekụla nke hydroxyethyl cellulose na-ekpebikwa viscosity ya. Ndị arọ molekụla dị elu HEC na-enwekarị viscosities dị elu na ntinye aka nyere. Njirimara a dị mkpa mgbe ị na-ahọrọ otu ọkwa HEC maka otu ngwa.

N'ime usoro ọgwụ, a na-ejikarị hydroxyethylcellulose eme ihe dị ka ihe na-eme ka ọ sie ike n'ụdị ọnụ na n'elu usoro onunu ogwu. The viscosity nke HEC na-eme ka nkwusioru kwesịrị ekwesị nke ahụ ma na-enye nkwụsi ike achọrọ maka dosing dị mfe. Ọzọkwa, omume na-akpụ akpụ nke HEC nwere ike imeziwanye mgbasawanye nke usoro nhazi.

N'ụlọ ọrụ ịchọ mma, a na-eji hydroxyethylcellulose na ngwaahịa dị iche iche, gụnyere shampoos, lotions na creams. Ngwongwo na-emezi viscosity ya na-enyere aka melite nkwụsi ike na udidi nke usoro ndị a, si otú ahụ na-eme ka ahụmịhe onye ọrụ na-abawanye.

N'ebe a na-ewu ihe owuwu, a na-ejikarị hydroxyethylcellulose eme ihe dị ka ihe na-esi ísì ụtọ na ngwaahịa ndị dabeere na ciment. Viscosity nke HEC na-enyere aka ịchịkwa usoro na nhazi nke ihe n'oge ngwa. Nke a dị mkpa karịsịa maka ngwa dị ka adhesives tile na grouts.

Viscosity nke hydroxyethyl cellulose bụ isi ihe na-emetụta arụmọrụ ya na ngwa dị iche iche. Ịghọta ihe ndị na-emetụta viscosity, dị ka ntinye uche, okpomọkụ, na ọnụ ọgụgụ shear, dị oke mkpa iji kwalite ojiji nke HEC na ụlọ ọrụ dị iche iche. Dị ka polymer na-agbanwe agbanwe, hydroxyethyl cellulose na-aga n'ihu na-arụ ọrụ dị mkpa n'ịkwalite arụmọrụ nke ngwaahịa dị iche iche n'ofe ụlọ ọrụ dị iche iche.
