Carboxymethyl cellulose ọ bụ cellulose ether?

Okwu Mmalite nke Carboxymethyl Cellulose (CMC)

Carboxymethyl cellulose, nke a na-akpọkarị CMC, bụ ihe na-esi na cellulose pụta, bụ polymer na-emekarị na mgbidi cell nke osisi. A na-enweta ya site na mgbanwe kemịkalụ nke cellulose, nke bụ isi site na iwebata otu carboxymethyl (-CH2-COOH) n'ime ọkpụkpụ azụ cellulose.

Ọdịdị na Njirimara

CMC na-ejigide ntọala ntọala nke cellulose, nke bụ eriri ahịrị nke molekul glucose jikọtara ya na β(1→4) glycosidic bonds. Agbanyeghị, iwebata otu carboxymethyl na-enye CMC ọtụtụ ihe dị mkpa:

Mmiri Solubility: N'adịghị ka nwa afọ cellulose, nke na-adịghị ike soluble na mmiri, CMC bụ nke ukwuu soluble na ma mmiri ọkụ na oyi n'ihi na hydrophilic ọdịdị nke carboxymethyl otu.

Ihe na-eme ka ọ dị arọ: CMC bụ onye na-emepụta ihe na-arụ ọrụ nke ọma, na-emepụta ngwọta viscous na obere mkpokọta. Ihe onwunwe a na-eme ka ọ baa uru n'ọtụtụ ngwa ngwa, gụnyere nri, ọgwụ na ngwaahịa nlekọta onwe onye.

Ikike imepụta ihe nkiri: CMC nwere ike ịmepụta ihe nkiri mgbe etinyere ya na ngwọta, na-eme ka ọ baa uru na ngwa ebe achọrọ ihe nkiri dị mkpa, na-agbanwe agbanwe, dị ka mkpuchi na nrapado.

Nkwụsi ike na ndakọrịta: CMC kwụsiri ike n'ọtụtụ pH na ọnọdụ okpomọkụ, na-eme ka ọ dakọtara na ihe ndị ọzọ dị iche iche ma dị mma maka ngwa dị iche iche.

Ngwa

Ngwongwo bara uru nke CMC na-achọta ngwa n'ofe ọtụtụ ụlọ ọrụ:

Ụlọ ọrụ nri: A na-eji CMC eme ihe n'ọtụtụ ebe dị ka thickener, stabilizer, na emulsifier na ngwaahịa nri dị ka sauces, uwe, ice cream, na ihe ebe a na-eme achịcha. Ọ na-eme ka ọdịdị ahụ dịkwuo mma, mmetụta ọnụ na nkwụsi ike shelf.

Ọgwụ: N'ime usoro ọgwụ, CMC na-eje ozi dị ka onye na-ekekọta, na-ekesa, na onye na-ahapụ njikwa na mbadamba na capsules. Ikike ya imepụta gels kwụsiri ike na-emekwa ka ọ baa uru n'ụdị usoro dị ka ude na lotions.

Ngwaahịa Nlekọta Onwe Onye: CMC bụ ihe a na-ahụkarị na ngwaahịa nlekọta onwe onye dị ka ntacha eze, ncha ntutu na ude, ebe ọ na-arụ ọrụ dị ka ihe na-agba agba, nkwụsi ike, na mmiri na-ejide mmiri.

Ụlọ ọrụ akwụkwọ: N'ime akwụkwọ, a na-eji CMC eme ihe dị ka onye na-emepụta ihe n'elu iji kwalite ike akwụkwọ, ire ụtọ, na nnabata ink. Ọ na-arụkwa ọrụ dị ka ihe enyemaka njide, na-enyere aka ijikọta ihe ndị dị mma na ndị na-ejuputa na akwụkwọ.

Textiles: A na-eji CMC n'ọrụ na mbipụta textile na usoro ịcha akwa dị ka ihe na-agbapụta agba na rheology modifier maka ibi akwụkwọ tapawa na ịsa akwa.

Ngwunye mmanụ: N'ụlọ ọrụ na-egwupụta mmanụ, a na-agbakwunye CMC na mmiri na-egwupụta mmiri iji nye njikwa viscosity, mbelata mbelata mmiri mmiri, na mmanu nke olulu mmiri.

A na-ekwukarị ojiji nke carboxymethyl cellulose na nchikota pụrụ iche nke akụrụngwa ya, nke na-eme ka ngwa ya na mpaghara dị iche iche. Biodegradability ya na enweghị nsí na-enye aka na mkpesa ya dị ka ihe na-adịgide adịgide na gburugburu ebe obibi na-akwado polymers sịntetik n'ọtụtụ ngwa.

carboxymethyl cellulose bụ n'ezie cellulose ether nwere ọtụtụ ngwa ngwa n'ihi na mmiri solubility ya, nkwụsi ike Njirimara, nkwụsi ike, na ndakọrịta na ndị ọzọ bekee. Ihe ọ pụtara na-agbasa n'ofe ụlọ ọrụ, na-eme ka ọ bụrụ akụkụ bara uru n'ọtụtụ ngwaahịa na usoro.
