Carboxymethylcellulose (CMC) na starch bụ ma polysaccharides, ma ha nwere dị iche iche ihe owuwu, Njirimara na ngwa.
Ngwakọta molekụla:
1. Carboxymethylcellulose (CMC):
Carboxymethylcellulose bụ ihe sitere na cellulose, polymer linear nke mejupụtara nkeji glucose jikọtara ya na njikọ β-1,4-glycosidic.Mgbanwe nke cellulose gụnyere iwebata otu carboxymethyl site na etherification, na-emepụta carboxymethylcellulose.Otu carboxymethyl na-eme ka mmiri CMC na-agbaze ma na-enye polymer pụrụ iche Njirimara.
2. Starch:
Starch bụ carbohydrate nke mejupụtara nkeji glucose jikọtara ya na njikọ α-1,4-glycosidic.Ọ bụ polymer eke dị na osisi nke a na-eji dị ka ihe nchekwa nchekwa ike.Ihe mejupụtara mkpụrụ ndụ starch n'ozuzu ya bụ ụdị abụọ nke polymers glucose: amylose (agbụ kwụ ọtọ) na amylopectin (agbụ agbụ alaka).
Njirimara anụ ahụ:
1. Carboxymethylcellulose (CMC):
Solubility: CMC bụ mmiri-soluble n'ihi ọnụnọ nke carboxymethyl otu.
Viscosity: Ọ na-egosipụta nnukwu viscosity na ngwọta, na-eme ka ọ baa uru na ngwa dị iche iche dị ka nhazi nri na ọgwụ.
Nghọta: Ngwọta CMC na-apụtakarị ìhè.
2. Starch:
Solubility: Starch obodo bụ ihe a na-apụghị ịsacha na mmiri.Ọ na-achọ gelatinization (ọkụ na mmiri) iji gbazee.
Viscosity: Tapawa starch nwere viscosity, mana ọ na-adịkarị ala karịa CMC.
Nghọta: Tapawa starch na-abụkarị opaque, na ogo opacity nwere ike ịdị iche dabere n'ụdị starch.
isi mmalite:
1. Carboxymethylcellulose (CMC):
A na-emekarị CMC site na cellulose sitere na isi mmalite osisi dịka pulp osisi ma ọ bụ owu.
2. Starch:
Osisi ndị dị ka ọka, ọka wit, poteto na osikapa nwere nnukwu starch.Ọ bụ isi ihe dị n'ọtụtụ nri nri.
Usoro mmepụta:
1. Carboxymethylcellulose (CMC):
Mmepụta nke CMC gụnyere mmeghachi omume etherification nke cellulose na chloroacetic acid na ọkara alkaline.Mmeghachi omume a na-ebute nnọchi nke otu hydroxyl na cellulose na otu carboxymethyl.
2. Starch:
Mwepụta starch gụnyere ịkụda mkpụrụ ndụ ihe ọkụkụ na ikewapụ granules starch.Starch ewepụtara nwere ike ime usoro dị iche iche, gụnyere mgbanwe na gelatinization, iji nweta ihe ndị achọrọ.
Ebumnuche na ngwa:
1. Carboxymethylcellulose (CMC):
Ụlọ ọrụ nri: A na-eji CMC eme ihe dị ka ihe na-esi ísì, stabilizer na emulsifier na nri dị iche iche.
Pharmaceuticals: N'ihi njide ya na nke na-emebi emebi, ọ na-ahụ na ejiri ya mee ihe n'ụdị ọgwụ.
Ngwunye mmanụ: A na-eji CMC na mmiri na-egwupụta mmanụ iji chịkwaa rheology.
2. Starch:
Ụlọ ọrụ nri: Starch bụ isi ihe dị n'ọtụtụ nri ma ejiri ya mee ihe dị ka ihe na-eme ka ọ dị arọ, onye na-ahụ maka gelling na stabilizer.
Ụlọ ọrụ akwa: A na-eji starch eme ihe na nha akwa iji mee ka akwa akwa sie ike.
Ụlọ ọrụ akwụkwọ: A na-eji starch eme akwụkwọ iji mee ka ike akwụkwọ dịkwuo mma ma melite njirimara elu.
Ọ bụ ezie na CMC na starch bụ ma polysaccharides, ha nwere ọdịiche dị na ihe mejupụtara molekụla, ihe anụ ahụ, isi mmalite, usoro mmepụta na ngwa.CMC bụ mmiri soluble na nke ukwuu viscous na a na-ahọrọkarị na ngwa chọrọ akụrụngwa ndị a, ebe starch bụ polysaccharide dị iche iche nke a na-ejikarị eme ihe na ụlọ ọrụ nri, textile na akwụkwọ.Ịghọta ọdịiche ndị a dị oke mkpa maka ịhọrọ polymer kwesịrị ekwesị maka ngwa ụlọ ọrụ na azụmahịa.
