Cellulose ethers

Cellulose ethers bụ ezinụlọ nke polysaccharides nke sitere na cellulose, polymer eke kachasị ukwuu n'ụwa.Ha na-agbaze mmiri ma nwee ọtụtụ ngwa na ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, ihe ịchọ mma, na ihe owuwu.N'isiokwu a, anyị ga-atụle ihe onwunwe, mmepụta, na ngwa nke cellulose ethers n'ụzọ zuru ezu.

Njirimara nke cellulose ethers

Cellulose ethers nwere ngwakọta pụrụ iche nke na-eme ka ha baa uru nke ukwuu na ngwa dị iche iche.Ụfọdụ n'ime ihe ndị bụ isi nke cellulose ethers gụnyere:

Mmiri Solubility: Cellulose ethers bụ nnukwu mmiri soluble, nke na-eme ka ọ dị mfe iji na usoro mmiri.Nke a na ihe onwunwe na-emekwa ka ha irè thickeners na stabilizers na nri na ọgwụ formulations.

Ihe Na-emepụta Ihe nkiri: Cellulose ethers nwere ike ịmepụta ihe nkiri doro anya, na-agbanwe agbanwe na siri ike mgbe agbazere ha na mmiri.Ngwongwo a bara uru na mmepụta nke mkpuchi, ihe mkpuchi, na ihe nkiri.

Nkwụsi ike nke kemịkalụ: Cellulose ethers kwụsiri ike na kemịkalụ ma na-eguzogide mmebi microbial, nke na-eme ka ha dị mma maka ojiji na ngwa ụlọ ọrụ dị iche iche.

Na-adịghị egbu egbu: Cellulose ethers adịghị egbu egbu ma dị mma maka iji nri, ọgwụ na ngwaahịa nlekọta onwe onye.

Mmepụta nke cellulose ethers

A na-emepụta ethers cellulose site n'ịgbanwe cellulose site na mmeghachi omume kemịkalụ na otu ọrụ dị iche iche.Ụdị cellulose ethers ndị a na-ahụkarị gụnyere:

Methylcellulose (MC): Methylcellulose na-emepụta site na imeghachi cellulose na methyl chloride na sodium hydroxide.A na-eji ya eme ihe n'ọtụtụ ebe dị ka thickener na stabilizer na nri na ọgwụ usoro.

Hydroxypropyl Cellulose (HPC): A na-emepụta hydroxypropyl cellulose site na imeghachi cellulose na propylene oxide na hydrochloric acid.A na-eji ya dị ka ihe nkedo, emulsifier, na thickener na nri, ọgwụ na ngwaahịa nlekọta onwe onye.

Ethylcellulose (EC): Ethylcellulose na-emepụta site na imeghachi cellulose na ethyl chloride na sodium hydroxide.A na-eji ya dị ka onye na-ekekọta ihe, onye na-emepụta ihe nkiri, na mkpuchi mkpuchi na ụlọ ọrụ ọgwụ na nlekọta onwe onye.

Carboxymethyl Cellulose (CMC): Carboxymethyl cellulose na-emepụta site na-emeghachi omume cellulose na chloroacetic acid na sodium hydroxide.A na-eji ya dị ka ihe na-agbapụta, stabilizer, na emulsifier na nri, ọgwụ na ụlọ ọrụ nlekọta onwe onye.

Hydroxyethyl Cellulose (HEC): A na-emepụta hydroxyethyl cellulose site na imeghachi cellulose na ethylene oxide na sodium hydroxide.A na-eji ya dị ka ihe na-agbapụta, stabilizer, na emulsifier na nri, ọgwụ na ụlọ ọrụ nlekọta onwe onye.

Ngwa nke Cellulose Ethers

Cellulose ethers nwere ọtụtụ ngwa dị iche iche na ụlọ ọrụ dị iche iche, gụnyere:

Ụlọ ọrụ nri: A na-eji cellulose ethers eme ihe dị ka ndị na-agbapụta ihe, ndị na-eme ka ọkpụkpụ na emulsifiers na nhazi nri.A na-eji ha eme ihe na ngwaahịa ndị dị ka ice cream, sauces, uwe, na ihe ndị a na-esi nri.

Ụlọ ọrụ na-emepụta ọgwụ: A na-eji ethers cellulose mee ihe dị ka ndị na-ekekọta, ndị na-ekesa, na mkpuchi na usoro ọgwụ.A na-eji ha na mbadamba mbadamba, capsules, na ụdị usoro ọgwụgwọ siri ike ndị ọzọ.

Ụlọ ọrụ nlekọta onwe onye: A na-eji ethers cellulose eme ihe dị ka ndị na-esi ísì, ihe nkwụnye na emulsifiers na ngwaahịa nlekọta onwe onye dị ka shampoos, lotions, na creams.

Ụlọ ọrụ ihe owuwu: A na-eji ethers cellulose mee ihe dị ka ihe na-ejigide mmiri, ihe na-agbapụta, na ihe eji emepụta ihe na ihe owuwu dị ka ciment, ngwa agha.
