Gịnị bụ sodium carboxymethyl cellulose?

Sodium carboxymethyl cellulose (CMC) bụ ihe soluble mmiri sitere na cellulose, nke bụ polysaccharide sitere n'okike dị na mgbidi cell osisi. A na-emepụta CMC site na mgbanwe kemịkalụ nke cellulose, ebe a na-ewebata otu carboxymethyl (-CH2COONa) na ọkpụkpụ azụ cellulose.

Iwebata otu carboxymethyl na-enye ọtụtụ ihe dị mkpa na cellulose, na-eme ka CMC bụrụ ihe mgbakwunye bara uru na ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, ihe ịchọ mma, nlekọta onwe onye, ​​akwa akwa na ngwa ụlọ ọrụ. Ụfọdụ n'ime ihe ndị bụ isi na ọrụ nke sodium carboxymethyl cellulose gụnyere:

1. Mmiri Solubility: CMC bụ nke ukwuu soluble na mmiri, akpụ doro anya, viscous ngwọta. Ngwongwo a na-enye ohere maka njikwa dị mfe yana itinye n'ime sistemu mmiri dị ka ngwaahịa nri, ọgwụ na usoro nlekọta onwe onye.
2. Thickening: CMC na-arụ ọrụ dị ka onye na-eme ka ọ dị arọ, na-abawanye viscosity nke ngwọta na nkwusioru. Ọ na-enyere aka inye ahụ na udidi na ngwaahịa ndị dị ka sauces, uwe, ude, na lotions.
3. Nkwụsi ike: CMC na-arụ ọrụ dị ka ihe nkwụsi ike site na igbochi nchịkọta na nhazi nke irighiri ma ọ bụ ụmụ irighiri mmiri na nkwusioru ma ọ bụ emulsions. Ọ na-enyere aka ịnọgide na-enwe nkesa nke ihe eji eme ihe ma na-egbochi nkewa nke oge n'oge nchekwa na njikwa.
4. Njide mmiri: CMC nwere ezigbo njide mmiri, na-ekwe ka ọ banye na ijide nnukwu mmiri. Ngwongwo a bara uru na ngwa ebe njide mmiri dị mkpa, dị ka n'ime ngwaahịa esiri esi, ihe oriri na ngwaahịa nlekọta onwe onye.
5. Nhazi ihe nkiri: CMC nwere ike ịmepụta ihe nkiri doro anya, na-agbanwe agbanwe mgbe akpọnwụwo, na-enye ihe mgbochi na nchebe mmiri. A na-eji ya na mkpuchi, ihe mkpuchi, na mbadamba ọgwụ na-emepụta ihe nkiri nchebe na mkpuchi.
6. Njide: CMC na-arụ ọrụ dị ka ihe nkedo site n'ịme njikọ nrapado n'etiti irighiri ma ọ bụ ihe ndị dị na ngwakọta. A na-eji ya na mbadamba ọgwụ, ceramics, na usoro ndị ọzọ siri ike iji meziwanye njikọ na ike mbadamba.
7. Mgbanwe Rheology: CMC nwere ike gbanwee njirimara rheological nke ngwọta, na-emetụta omume ịgba ọsọ, viscosity, na àgwà mkparị. A na-eji ya iji chịkwaa ọsọ na udidi nke ngwaahịa dị ka agba, ink na mmiri mmiri.

sodium carboxymethyl cellulose bụ ihe mgbakwunye multifunctional nwere ọtụtụ ngwa n'ofe ụlọ ọrụ dị iche iche. Ntughari ya, mmiri solubility, ndim, nkwụsi ike, njigide mmiri, imepụta ihe nkiri, njide, na rheology-modifying Njirimara na-eme ka ọ bụrụ ihe bara uru na ngwaahịa na nhazi na-enweghị atụ.
