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

Cellulose ethernwere ike ime ka arụmọrụ nke ngwa agha mmiri dịkwuo mma nke ukwuu, ọ bụkwa ihe mgbakwunye bụ isi nke na-emetụta arụmọrụ owuwu nke ngwa agha. 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 ngwa agha ntụ ntụ kpọrọ nkụ.

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.

Ibu dị elu nke molekulcellulose ethernwere oke arụmọrụ siri ike. Polymers nwere oke molekul dị iche iche nwere oke dị iche iche n'otu ngwọta njupụta. Oke dị elu. Enwere ike inweta oke viscosity ebumnuche naanị site na ịgbakwunye nnukwu oke molekul dị ala cellulose ether. Oke viscosity ya anaghị adabere na ọnụego nchapụta, oke viscosity ahụ na-erukwa oke viscosity ebumnuche, oke mgbakwunye achọrọ dịkwa obere, oke viscosity ahụ dabere na arụmọrụ siri ike. Ya mere, iji nweta otu nkwekọ, a ga-enwerịrị oke viscosity cellulose 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 otu njupụta. Oke gelling nke HPMC dị elu na okpomọkụ ụlọ.
