Cellulose ethers bụ otu polymers bara ụba na nke a na-ejikarị eme ihe nke sitere na cellulose, polysaccharide eke dị na mgbidi cell osisi.A na-eji ihe ndị a na-emepụta polymer site na mmiri solubility, biodegradability, na ihe ndị na-emepụta ihe nkiri.Ọ bụ ezie na a naghị eji cellulose ether eme ihe ozugbo n'ichepụta plastik ọdịnala, ha na-arụ ọrụ dị mkpa n'ụlọ ọrụ dị iche iche dịka ọgwụ, nri, ihe owuwu na akwa.
Cellulose Ethers: nkọwa
Cellulose bụ polymer organic kasị baa ụba n'ụwa, na mmepụta ya, nke a na-akpọ cellulose ethers, na-emepụta site na mgbanwe kemịkalụ nke mkpụrụ ndụ cellulose.Isi mmalite nke cellulose na-agụnye pulp osisi, owu, na eriri osisi ndị ọzọ.
Isi cellulose ethers gụnyere:
Methylcellulose (MC): Emepụtara site na iji dochie otu hydroxyl nke cellulose na otu methyl, a na-ejikarị MC eme ihe na ụlọ ọrụ nri, ọgwụ na ihe owuwu.A maara ya maka ihe eji echekwa mmiri, na-eme ka ọ bụrụ ihe mgbakwunye dị mma na ngwa dị iche iche.
Hydroxypropylcellulose (HPC): Na mmepụta nke a, otu hydroxypropyl nọchiri anya otu hydroxyl nke cellulose.A na-ejikarị HPC na-emepụta ọgwụ, ihe ịchọ mma, na ngwaahịa nlekọta onwe onye n'ihi mmepụta ihe nkiri na ihe na-eme ka ọ dị arọ.
Hydroxyethyl cellulose (HEC): A na-enweta HEC site na iwebata ìgwè hydroxyethyl n'ime cellulose.A na-eji ya dị ka ihe na-agbapụta, ihe nkedo na stabilizer na ụlọ ọrụ dịka nrapado, agba na ngwaahịa nlekọta onwe onye.
Carboxymethylcellulose (CMC): A na-enweta CMC site na iji otu carboxymethyl dochie akụkụ nke hydroxyl.A na-eji ya n'ọtụtụ ebe na ụlọ ọrụ nri dị ka onye na-agba ume na stabilizer na ụlọ ọrụ ọgwụ maka ihe nrapado ya.
Ngwa nke cellulose ethers
1. Ụlọ ọrụ nri:
A na-eji cellulose ethers, karịsịa CMC, mee ihe n'ọtụtụ ebe na ụlọ ọrụ nri iji kwalite ọdịdị, nkwụsi ike na viscosity nke ngwaahịa dị iche iche dị ka ice cream, uwe salad na ngwaahịa esi nri.
2. Ọgwụ:
A na-eji Methylcellulose na cellulose ethers ndị ọzọ na-emepụta ọgwụ dị ka ihe na-ekekọta, ihe na-emepụta ihe na ihe nkiri na-emepụta mbadamba nkume.
3. Ụlọ ọrụ ihe owuwu:
A na-ejikarị HEC na MC eme ihe na ụlọ ọrụ mmepụta ihe iji melite arụmọrụ nke ngwa agha, nrapado na mkpuchi.Ha na-enyere aka melite arụmọrụ na njigide mmiri.
4. Ngwaahịa nlekọta onwe onye:
Hydroxypropyl cellulose na hydroxyethyl cellulose dị na ngwaahịa nlekọta onwe onye dị ka shampoos, lotions na cosmetics, na-enye viscosity na nkwụsi ike.
5. Akwa:
A na-eji ethers cellulose eme ihe na mbipụta textile na usoro ịcha akwa n'ihi na ha na-eme ka ha sie ike na nkwụsi ike.
Cellulose ethers nwere ọtụtụ uru gburugburu ebe obibi:
Nkwalite ndụ:
N'adịghị ka ọtụtụ polymers sịntetik, cellulose ethers bụ ihe na-emebi emebi, nke pụtara na ha na-agbaji site na usoro okike, na-ebelata mmetụta ha na gburugburu ebe obibi.
Ike emeghari ohuru:
Cellulose, akụrụngwa maka cellulose ethers, sitere na ihe ndị a na-emegharị ọhụrụ dị ka osisi na eriri osisi.
