Njirimara nke cellulose ethers

Cellulose ethers na-enye ezigbo viscosity nye slastic mmiri mmiri, na-eme ka ikike njikọ nke slastic mmiri mmiri na substrate dịkwuo elu ma na-eme ka iguzogide slacking nke slacing dịkwuo mma, a na-ejikwa ha nke ọma na slasting slacing, brik connection slacing na mpụta slasting systems. Mmetụta siri ike nke cellulose ether nwekwara ike ime ka ikike mgbochi mgbasa na ịdị n'otu nke ihe ndị a gwakọtara ọhụrụ dịkwuo elu, gbochie delamination ihe, nkewa na mmiri na-apụta, a pụkwara iji ya na slastic fiber, slastic mmiri na slacing onwe ya.

Mmetụta siri ike nke cellulose ethers na ihe simenti na-esi na viscosity nke ihe ngwọta cellulose ether pụta. N'otu ọnọdụ ahụ, ka viscosity nke cellulose ether na-abawanye, otú ahụ ka viscosity nke ihe simenti agbanwere ka mma, mana ọ bụrụ na viscosity dị oke elu, ọ ga-emetụta mmiri na ike ọrụ nke ihe ahụ (dịka ọmụmaatụ mma plasta na-arapara arapara). Mkpụrụ osisi na-agbanwe onwe ya na simenti na-akpakọ onwe ya, nke chọrọ mmiri dị elu, chọrọ obere viscosity nke cellulose ethers. Na mgbakwunye, mmetụta siri ike nke cellulose ethers na-eme ka mmiri chọrọ ihe simenti ma na-eme ka mmepụta nke simenti dịkwuo elu.

Ọbara nke ihe ngwọta ether cellulose na-adabere na ihe ndị a: oke molekul nke cellulose ether, ntinye uche, okpomọkụ, ọnụego shear na usoro nnwale. N'otu ọnọdụ ahụ, ka oke molekul nke cellulose ether na-abawanye, ka viscosity nke ngwọta ahụ na-abawanye; ka ntinye uche ahụ na-abawanye, ka viscosity nke ngwọta ahụ na-abawanye, a ga-elebara anya iji zere oke dose ma metụta ihe onwunwe ọrụ nke moto na simenti; viscosity nke ngwọta ether cellulose ga-ebelata ka okpomọkụ na-abawanye, na ka ntinye uche ahụ na-abawanye, ka mmetụta nke okpomọkụ na-abawanye; solution ether cellulose na-abụkarị mmiri pseudoplastic, yana ọdịdị nke shear thinning, ka nnwale ahụ na-abawanye. Ka ọnụego shear nke ule ahụ na-abawanye, ka viscosity ahụ na-adị obere, yabụ njikọ nke moto ahụ ga-ebelata n'okpuru ọrụ nke ike mpụga, nke na-enyere aka na nhazi mkpocha nke moto, ka moto ahụ wee nwee ike ịrụ ọrụ nke ọma na njikọta n'otu oge; n'ihi na ngwọta ether cellulose cellulose bụ mmiri na-abụghị Newtonian, ụzọ nnwale viscosity nke ule, ngwaọrụ ma ọ bụ gburugburu nnwale, otu nsonaazụ ule ngwọta ether cellulose nwere ike ịdị iche nke ukwuu.
