Carboxymethylcellulose (CMC) na starch bụ polysaccharides, mana ha nwere nhazi, ihe onwunwe na ojiji dị iche iche.
Ngwakọta molekụla:
1. Carboxymethylcellulose (CMC):
Carboxymethylcellulose bụ ihe sitere na cellulose, polima linear nke mejupụtara nkeji glucose jikọtara site na njikọ β-1,4-glycosidic. Mgbanwe nke cellulose gụnyere iwebata otu carboxymethyl site na etherification, na-emepụta carboxymethylcellulose. Otu carboxymethyl na-eme ka CMC na-agbaze mmiri ma na-enye polymer pụrụ iche.
2. Starch:
Starch bụ carbohydrate nke mejupụtara nkeji glucose nke ejiri njikọ α-1,4-glycosidic jikọtara. Ọ bụ polima eke nke a na-ahụ n'ime osisi nke a na-eji dị ka ihe nchekwa ike. Mkpụrụ ndụ starch na-abụkarị ụdị polima glucose abụọ: amylose (agbụ kwụ ọtọ) na amylopectin (usoro agbụ ígwè).
Njirimara anụ ahụ:
1. Carboxymethylcellulose (CMC):
Mmiri na-agbaze: CMC na-agbaze mmiri n'ihi ọnụnọ nke otu carboxymethyl.
Viscosity: Ọ na-egosi oke viscosity na mmiri, nke na-eme ka ọ baa uru n'ọtụtụ ọrụ dịka nhazi nri na ọgwụ.
Ndozi: Ngwọta CMC na-apụta ìhè nke ọma.
2. Starch:
Mmiri: Starch nke sitere n'okike anaghị agbaze n'ime mmiri. Ọ chọrọ ka a na-ekpo ọkụ na mmiri (kpoo ọkụ) iji gbazee.
Viscosity: Ntucha starch nwere viscosity, mana ọ na-adịkarị ala karịa CMC.
Ndozigharị: Ndochi starch na-adịkarịghị agbagọ agbagọ, oke nke agbagọ agbagọ nwekwara ike ịdị iche dabere n'ụdị starch ahụ.
isi mmalite:
1. Carboxymethylcellulose (CMC):
A na-ejikarị cellulose eme CMC site na ihe ọkụkụ dịka osisi pulp ma ọ bụ owu.
2. Starch:
Osisi dịka ọka, wit, nduku na osikapa bara ụba na starch. Ọ bụ isi ihe dị na ọtụtụ nri ndị a na-eri.
Usoro Mmepụta:
1. Carboxymethylcellulose (CMC):
Mmepụta nke CMC gụnyere mmeghachi omume etherification nke cellulose na chloroacetic acid n'ime ihe alkaline. Mmeghachi omume a na-eme ka e jiri otu carboxymethyl dochie otu hydroxyl na cellulose.
2. Starch:
Ịmịpụta starch gụnyere imebi mkpụrụ ndụ osisi na ikewapụ mkpụrụ ndụ starch. Starch ewepụtara nwere ike ịgafe usoro dị iche iche, gụnyere mgbanwe na nhazi gelatin, iji nweta ihe ndị achọrọ.
Ebumnuche na ojiji:
1. Carboxymethylcellulose (CMC):
Ụlọ ọrụ nri: A na-eji CMC eme ihe dị ka ihe na-eme ka ihe sie ike, ihe na-eme ka ihe sie ike, na ihe na-eme ka ihe dị nro n'ọtụtụ nri.
Ọgwụ: N'ihi na ọ na-ejikọta ma na-agbawa agbawa, a na-eji ya eme ihe n'ụdị ọgwụ.
Ịgwupụta Mmanụ: A na-eji CMC eme ihe n'ime mmiri ịgbapụta mmanụ iji chịkwaa rheology.
2. Starch:
Ụlọ ọrụ nri: Starch bụ isi ihe dị n'ọtụtụ nri ma a na-eji ya eme ihe dị ka ihe na-eme ka ihe sie ike, ihe na-eme ka ihe sie ike na ihe na-eme ka ahụ sie ike.
Ụlọ ọrụ ákwà: A na-eji starch eme nha ákwà iji mee ka ákwà sie ike.
Ụlọ ọrụ akwụkwọ: A na-eji starch eme akwụkwọ iji mee ka ike akwụkwọ dịkwuo elu ma melite ọdịdị elu ya.
Ọ bụ ezie na CMC na starch bụ polysaccharides, ha nwere ọdịiche dị na nhazi molekul, ihe ndị dị na anụ ahụ, isi mmalite, usoro mmepụta na ojiji. CMC na-agbaze mmiri ma na-acha ọbara ọbara nke ukwuu, a na-ahọrọkarị ya na ngwa ndị chọrọ ihe ndị a, ebe starch bụ polysaccharide dị iche iche a na-ejikarị eme ihe n'ụlọ ọrụ nri, ákwà na akwụkwọ. Ịghọta ọdịiche ndị a dị oke mkpa iji họrọ polima kwesịrị ekwesị maka ngwa ụlọ ọrụ mmepụta ihe na azụmahịa kpọmkwem.
