Usoro nke Cellulose na Ngwakọta Na-eme Ka Ọ Gburu Ibu

Cellulose ether nwere ike ime ka arụmọrụ nke moto mmiri dịkwuo mma nke ukwuu, ọ bụkwa ihe mgbakwunye bụ isi nke na-emetụta arụmọrụ owuwu nke moto. Nhọrọ ezi uche dị na ya nke ethers cellulose nke ụdị dị iche iche, viscosities dị iche iche, nha ihe dị iche iche, ogo viscosity dị iche iche na ọnụọgụ agbakwunyere ga-enwe mmetụta dị mma na mmezi nke arụmọrụ nke moto ntụ akọrọ.

E nwekwara ezigbo mmekọrịta dị n'etiti nguzosi ike nke simenti na usoro nke cellulose ether. Cellulose ether nwere ike ime ka viscosity nke mortar dịkwuo elu. Ka usoro onunu buru ibu, otú ahụ ka mmetụta ya na-apụta ìhè. Mmiri mmiri cellulose ether dị elu nwere thixotropy dị elu, nke bụkwa ihe bụ isi e ji mara cellulose ether.

Mmetụta nke ihe siri ike na-adabere n'ọkwa polymerization nke cellulose ether, ntinye nke ihe ngwọta, ọnụego shear, okpomọkụ na ọnọdụ ndị ọzọ. Njirimara gelling nke ihe ngwọta ahụ pụrụ iche na alkyl cellulose na ihe ndị sitere na ya agbanwere agbanwe. Njirimara gelation metụtara ogo nnọchi, ntinye nke ihe ngwọta na ihe mgbakwunye. Maka ihe ndị sitere na hydroxyalkyl gbanwere, ihe ndị sitere na gel ahụ jikọtara ya na ogo mgbanwe nke hydroxyalkyl. Enwere ike ịkwadebe 10%-15% ngwọta maka MC na HPMC dị ala, enwere ike ịkwadebe 5%-10% ngwọta maka MC na HPMC dị ọkara, enwere ike ịkwadebe 2%-3% ngwọta naanị maka MC na HPMC dị elu. Ọtụtụ mgbe, a na-ejikwa 1%-2% ngwọta nhazi viscosity nke cellulose ether.

Ether cellulose dị arọ nke nwere molekul dị elu nwere oke mmepụta siri ike. Polymers nwere molekul dị iche iche nwere viscosity dị iche iche n'otu ngwọta ntinye. Oke ogo. Enwere ike inweta viscosity ebumnuche naanị site na ịgbakwunye nnukwu molekul dị arọ nke cellulose ether dị ala. viscosity ya anaghị adabere na ọnụego ịkpụ, viscosity dị elu na-erukwa viscosity ebumnuche, ego mgbakwunye achọrọ dịkwa obere, viscosity dabere na arụmọrụ stimulation. Ya mere, iji nweta otu nkwekọ, a ga-enwerịrị nkwa na a ga-emerịrị ụfọdụ cellular ether (ntinye nke ngwọta) na viscosity ngwọta. Okpomọkụ gel nke ngwọta ahụ na-ebelatakwa n'usoro ka mmụba nke ntinye nke ngwọta ahụ, na gels na okpomọkụ ụlọ mgbe ọ ruru ụfọdụ propionation. Ntinye gelling nke HPMC dị elu na okpomọkụ ụlọ.
