Cellulose ether (HPMC, MC, HEC, EC, HPC, CMC, PAC)

Cellulose ethers bụ otu polymers soluble mmiri nke sitere na cellulose, polymer eke dị na mgbidi cell osisi. A na-eji ha eme ihe n'ọtụtụ ụlọ ọrụ dị iche iche maka ihe ha na-eme ka ha sie ike, na-eme ka ọ dị ike, na-emepụta ihe nkiri, na-ejigide mmiri. Nke a bụ nkọwa dị nkenke nke ụfọdụ ụdị cellulose ethers a na-ahụkarị:

1. Hydroxypropyl Methylcellulose (HPMC): HPMC bụ cellulose ether dị iche iche nke a na-ejikarị na-ewu, ọgwụ, nlekọta onwe onye, ​​​​na ụlọ ọrụ nri. A maara ya maka njide mmiri ya dị mma, nke siri ike, na imepụta ihe nkiri. A na-ejikarị HPMC eme ihe dị ka thickener, binder, and rheology modifier na ngwa agha, nrapado tile, mbadamba ọgwụ, ihe ịchọ mma, na ngwaahịa nri.
2. Methylcellulose (MC): MC yiri HPMC mana nwere ogo dị ala nke nnọchi na otu methyl. A na-eji ya na ngwa ebe achọrọ njigide mmiri dị ala na viscosity, dị ka na usoro ọgwụ, ngwọta anya, na dị ka ihe na-esi ísì ụtọ na ngwaahịa nri.
3. Hydroxyethyl Cellulose (HEC): HEC bụ cellulose ether ọzọ a na-ejikarị eme ihe maka njigide mmiri dị mma na ihe na-eme ka ọ dịkwuo mma. A na-ejikarị ya eme ihe na-ewu ụlọ dị ka agba, mkpuchi, na nrapado, yana ngwaahịa nlekọta onwe onye dị ka shampoos, lotions, na ude.
4. Ethyl Cellulose (EC): EC bụ cellulose ether gbanwere na otu ethyl. A na-eji ya eme ihe na ọgwụ, mkpuchi, na ngwa ọpụrụiche ebe mmepụta ihe nkiri ya, ihe mgbochi na ihe ntọhapụ ya bara uru. A na-ejikarị EC eme ihe dị ka ihe mkpuchi maka mbadamba nkume na pellet na usoro ọgwụ.
5. Hydroxypropyl Cellulose (HPC): HPC bụ cellulose ether ejiri otu hydroxypropyl gbanwee. A na-ejikarị ya eme ihe dị ka onye na-agbakọ, ihe nkedo, na onye na-emepụta ihe nkiri na ọgwụ, ngwaahịa nlekọta onwe onye, ​​na ngwa nri. HPC na-enye ezigbo solubility, njikwa viscosity, na nkwụsi ike na ngwọta mmiri.
6. Carboxymethyl Cellulose (CMC): CMC bụ cellulose ether na-agbaze mmiri nke sitere na cellulose sitere na carboxymethylation. A na-eji ya eme ihe n'ọtụtụ ebe dị ka thickener, stabilizer, na ihe nkedo na ngwaahịa nri, ọgwụ, ngwaahịa nlekọta onwe onye, ​​na ngwa ụlọ ọrụ mmepụta ihe. CMC na-emepụta ihe ngwọta doro anya, viscous ma na-ejikarị ya dị ka ihe na-eme ka ọ sie ike na sauces, uwe, na nkwusioru ọnụ.
7. Polyanionic Cellulose (PAC): PAC bụ cellulose ether ejiri otu anionic gbanwee, nke na-abụkarị carboxymethyl ma ọ bụ otu phosphonate. A na-eji ya eme ihe n'ụzọ bụ isi dị ka ihe mgbakwunye njikwa mfu mmiri na-egwupụta mmiri maka nyocha mmanụ na gas. PAC na-enyere aka ibelata mfu mmiri, melite viscosity, na mee ka apịtị ndị na-egwupụta ihe kwụsie ike n'okpuru oke okpomọkụ na ọnọdụ nrụgide dị elu.

Ndị a cellulose ethers na-enye ọtụtụ ọrụ na ngwa dị iche iche n'ofe ụlọ ọrụ dị iche iche, na-enye aka na arụmọrụ, nkwụsi ike, na àgwà nke ọtụtụ ngwaahịa na nhazi.
