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-egbochi 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 nha nha, dị oke mkpa iji kwalite ojiji nke HEC na ụlọ ọrụ dị iche iche. Dị ka polymer dị iche iche, 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.
