Iji tulee cmc (carroxymethylclose) na hpmc (hydroxylmethylcelllose) A na-ejikarị igwe ojii ma cellose rụọ ọrụ n'ọtụtụ ebe, gụnyere ọgwụ, nri, ihe ịchọ mma na owuwu. Nke ọ bụla nwere ihe pụrụ iche na-eme ka ọ dị mma maka nzube dị iche iche. Ka anyị jiri ntụnyere dị omimi hụ ịhụ nke ka mma n'ọnọdụ dị iche iche.
1. Nkọwa na nhazi:
Cmc (caryxymethylcellose): cmc bụ mmiri - solulose cellutive derivase mepụtara site na mmeghachi omume nke cellose na chloroacetic acid. O nwere otu carnoxythylylyylyyyylyyyl (otu cooh) na ụfọdụ ndị otu Hydroxy nke ndị monan glucopinal nke na-eme mkpọtụ sellone.
HPMC (hydroxylthylthylthylmcelllose): hpmc bụkwa mmiri celluble derivase mepụtara site na ịgwọ ọrịa cellose na propylene oxide na methyl chloride. O nwere hydroxylyl na methoxy òtù na Methoxy Backbone.
2. Ngụgụ:
CMC: soluble na mmiri, na-etolite ụzọ, ngwọta viscous. Ọ na-egosipụta omume na-asọ asọ na-asọ, nke pụtara na vissity ya na-ebelata n'okpuru nrụgide Shear.
HPMC: Ọkpụkpụ na mmiri, na-etolite ngwọta dịtụ anya karịa cmc. Ọ na-egosipụtakwa omume pseudoploac.
3.Relogical Njirimara:
CMC: Egosiputa Ebumnuche Seear, nke pụtara na viset ya na-ebelata na ịba ụba nke ya. Ngwongwo a na - eme ka ọ dị mma maka ngwa ebe achọrọ mana ihe ga - achọ mfe n'okpuru ịkwa osisi, dị ka eserese, na - egbochi na ọgwụ ọgwụ.
HPMC: Ngosipụta omume na-egbu egbu na cmc, mana viscosity ya dị elu na mpe mpe mpe. Ọ nwere ihe dị mma na-akpụ akpụ ihe nkiri, na-eme ya dị mma maka ngwa ndị dị ka mkpuchi, adhesives na usoro ọgwụgwọ na-achịkwa ọgwụ.
4. Ike nkwụsi ike:
Cmc: n'ozuzu kwụrụ ọtọ na mbara igwe na okpomọkụ. Ọ nwere ike ịnagide ọkwa electrolytes na-agafeghị oke.
HPMC: kwụsiri ike karịa cmc n'okpuru ọnọdụ acidic, mana enwere ike ịnwe hydrolysis n'okpuru ọnọdụ alkaline. Ọ na-enwe mmetụta na-emetuta ala nke ike, nke nwere ike ibute geleli ma ọ bụ ọdịda.
5. Ngwa:
CMC: Ebe a na-ejikarị ya dị ka REMENENTER, mmachi na mmiri na-ejigide nri (dị ka ice cream, nke ọgwụ) na cosmetics (dị ka ude, ude mmiri) ụlọ ọrụ.
HPMC: A na-ejikarị ihe eji arụ ọrụ (dịka ọmụmaatụ, na mbadamba ọgwụ), na-achịkwa mbadamba), na anya, na-ahụ maka anụ ahụ.
6. Na-egbu egbu na nchekwa:
CMC: A na-amata na nchekwa (Gras) site na ụlọ ọrụ nchịkwa mgbe ejiri ya na ngwa na-eme ọgwụ. Ọ bụ biodegrable na-enweghị nsi.
HPMC: Ọzọkwa ewere dị ka ihe dị ka oriri n'ime oke a tụrụ aro. Ọ bụ biocompupu ma jiri ọtụtụ ihe na-emepụta ọgwụ dị ka onye na-ewepụta ọgwụ na mbadamba mbadamba.
7. Achịcha na nnweta:
CMC: A na-akwụsi ụgwọ karịa hpmc. Ọ dị mfe site na ndị ọrụ dị iche iche gburugburu ụwa.
HPMC: thintụ ọnụ karịa dị oke ọnụ n'ihi usoro mmepụta ya na mgbe ụfọdụ enweghị oke site na ụfọdụ ndị na-eweta.
8. Mmetụta gburugburu ebe obibi:
CMC: Biodegradeble, sitere na akụrụngwa mmeghari ohuru (Cellulose). A na-ahụta ya gburugburu ebe obibi.
HPMC: Ọzọkwa biodegradble ma nweta site na cellulose, yabụ gburugburu gburugburu ebe obibi na-enwe mmekọrịta.
Ma cmc na hpmc nwere ihe pụrụ iche na-eme ka ihe ndị bara uru bara uru n'ọtụtụ ụlọ ọrụ. Nhọrọ dị n'etiti ha na-adabere na ngwa a kapịrị ọnụ dị ka nlekọta, vists, kwụsie ike na echiche ọnụ. Na mkpokọta, enwere ike ịkwado CMC n'ihi ọnụ ahịa ya dị ala, weghara ike maka ngwa nri na ịchọ mma ngwa. N'aka nke ọzọ, enwere ike iji aka nke viccosite ya dị elu, ihe ndị na-akpụ akpụ ihe nkiri dị mma, na ngwa na ọgwụ na ihe ndị na-ewu ya. Na n'ikpeazụ, nhọrọ kwesịrị na-adabere n'echiche zuru oke banyere ihe ndị a na ndakọrịta ya na ebumnuche achọrọ.
