Ịbawanye viscosity nke cellulose ether ọ̀ ga-eme ka ọ̀tụ̀tụ̀ mmiri na-asọ asọ pụta?

Ịbawanye viscosity nke cellulose ethers n'ozuzu na-ebelata ọsọ ọsọ nke ngwọta.Cellulose ethers bụ otu polymers soluble mmiri sitere na cellulose nke a na-ejikarị eme ihe n'ọtụtụ ụlọ ọrụ, gụnyere ọgwụ, nri, na ihe owuwu.Viscosity nke ngwọta bụ ihe nrịbama nke nguzogide ya na-asọba ma na-emetụta ihe ndị dị ka ntinye uche, okpomọkụ, na ịdị arọ nke cellulose ether.

Nke a bụ nkọwa zuru ezu banyere otú ịba ụba cellulose ether viscosity si emetụta ọnụego eruba:

Mmekọrịta dị n'etiti viscosity na ọnụego eruba:

Viscosity bụ esemokwu dị n'ime n'ime mmiri nke na-eguzogide mgbaba ya.A na-atụ ya na nkeji dị ka centipoise (cP) ma ọ bụ pascal sekọnd (Pa·s).
Ọnụego mgbaba nke ihe ngwọta na-adaba na viscosity ya.Viscosity dị elu pụtara nkwụsi ike ka ukwuu na-asọpụta, na-eme ka ọ dị ala.

Njirimara nke cellulose ether:

A na-agbakwunyekarị ethers cellulose na ngwọta iji gbanwee njirimara rheological ya.Ụdị ndị a na-ahụkarị gụnyere methylcellulose (MC), hydroxypropylcellulose (HPC), na carboxymethylcellulose (CMC).
The viscosity nke cellulose ether ngwọta na-adabere na ihe ndị dị ka itinye uche, okpomọkụ na shear ọnụego.

Mmetụta itinye uche:

Ịba ụba nke cellulose ethers na-eme ka viscosity dịkwuo elu.Nke a bụ n'ihi na ntinye uche dị elu pụtara ọtụtụ agbụ polymer na ngwọta, na-eme ka nkwụsi ike dị ukwuu.

Mmetụta okpomọkụ:

Okpomọkụ na-emetụta viscosity nke cellulose ethers.N'ọnọdụ ụfọdụ, ka okpomọkụ na-abawanye, viscosity na-ebelata.Otú ọ dị, mmekọrịta a nwere ike ịdịgasị iche dabere na ụdị ether cellulose kpọmkwem na ihe ngwọta ya.

Ndabere ọnụ ọgụgụ shia:

Viscosity nke cellulose ether ngwọta n'ozuzu na-adabere na shiee ọnụego.N'ọkwa dị elu nke shear (dịka ọmụmaatụ, n'oge mgbapụta ma ọ bụ ịgwakọta), viscosity nwere ike ibelata n'ihi àgwà ịhịa aka n'ahụ.

Mmetụta na okporo ụzọ:

Ịbawanye viscosity cellulose ether nwere ike ime ka ọ̀tụ̀tụ̀ mmiri na-asọpụta belatara n'usoro chọrọ ibufe, ịgbapụta, ma ọ bụ inye ihe ngwọta.Nke a dị mkpa maka ngwa dị ka mkpuchi, nrapado na usoro ọgwụ.

Ngwa ndetu:

Ọ bụ ezie na enwere ike ịchọrọ viscosities dị elu na ngwa ụfọdụ iji melite arụmọrụ ngwaahịa ma ọ bụ nkwụsi ike, nke a ga-edozirịrị megide akụkụ bara uru nke njikwa na nhazi.

Nkwalite nri nri:

Ndị na-emepụta ihe na-ebuli mkpokọta cellulose ether na usoro nhazi ndị ọzọ iji nweta viscosity achọrọ maka otu ngwa na-enweghị emetụta ike ịgbasa na ogo na-adịghị anabata.

Ịba ụba nke cellulose ether viscosity na-ebutekarị mbelata nke ọsọ ọsọ n'ihi mmụba na-eguzogide mmiri.Otú ọ dị, mmekọrịta ahụ ziri ezi na-emetụta ihe ndị dị ka ntinye uche, okpomọkụ na nha nha, na nhazi nhazi nwere ike ime iji nweta nguzozi a chọrọ n'etiti viscosity na flowability.
