(Hydroxypropyl) methyl cellulose | CAS 9004-65-3

(Hydroxypropyl) methyl cellulose, nke a makwaara site na mbiri nke HPMC ma ọ bụ nọmba CAS ya 9004-65-3, bụ cellulose ether nke sitere na cellulose eke. Ọ bụ polymer synthetic nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche n'ihi njirimara pụrụ iche ya na ntụgharị ya. Nke a bụ nlele anya na ogige a:

Ọdịdị na Njirimara:
1 Ọdịdị: A na-emepụta HPMC site na mgbanwe kemịkalụ nke cellulose, ebe a na-ewebata otu methyl (-CH3) na hydroxypropyl (-CH2CHOHCH3) n'ime ọkpụkpụ azụ cellulose.
2 Degree of Substitution (DS): Ogo nke nnọchi na-ezo aka na nkezi ọnụ ọgụgụ nke ndị nnọchi anya otu glucose n'ime agbụ cellulose. Ọ na-ekpebi njirimara HPMC, dị ka solubility, viscosity, na ike imepụta ihe nkiri.
Ngwongwo 3: HPMC na-egosipụta ihe ndị dị ka ịgbara mmiri, njide mmiri, nhazi ihe nkiri, na ọrụ elu. Enwere ike ịhazi ihe ndị ahụ site na ịchịkwa DS n'oge njikọ.

Mmepụta:
1.Cellulose Sourcing: Cellulose, bụ isi akụrụngwa maka HPMC, na-esite na mmeghari isi mmalite dị ka osisi pulp ma ọ bụ owu.
Etherification: Cellulose na-enweta etherification, ebe a na-emeghachi ya na propylene oxide iji webata ìgwè hydroxypropyl na mgbe ahụ na methyl chloride iji gbakwunye otu methyl.
2.Purification: A na-eme ka cellulose a gbanwee iji wepụ ihe ndị na-adịghị ọcha na ngwaahịa, na-ebute ngwaahịa HPMC ikpeazụ.
Ngwa:
Ụlọ ọrụ 3.Construction: A na-eji HPMC eme ihe n'ọtụtụ ebe na ihe owuwu dị ka ụrọ ndị dabeere na ciment, plasta, na adhesives tile iji meziwanye ọrụ, njide mmiri, na adhesion.
4.Pharmaceuticals: Ọ ​​na-eje ozi dị ka ihe nkedo, thickener, film mbụ, na stabilizer na ọgwụ formulations gụnyere mbadamba nkume, capsules, ophthalmic ngwọta, na Topical ude.
Ụlọ ọrụ 5.Food: HPMC na-arụ ọrụ dị ka onye na-agba ume, stabilizer, na emulsifier na ngwaahịa nri dị iche iche dị ka sauces, uwe, ice creams, na ngwaahịa esi nri.
6.Cosmetics and Personal Care: N'ihe ịchọ mma na ngwaahịa nlekọta onwe onye, ​​a na-eji HPMC eme ihe dị ka onye na-agba agba, onye na-egbochi ihe nkiri, ihe nkiri mbụ, na moisturizer na ude, lotions, shampoos, na gels.
7.Paints na mkpuchi: Ọ na-eme ka viscosity dịkwuo mma, nguzogide sag, na mmepụta ihe nkiri nke agba mmiri, ihe mkpuchi, na mkpuchi.
Mmechi:
(Hydroxypropyl) methyl cellulose, yana ngwa dị iche iche na akụrụngwa bara uru, bụ ihe dị mkpa n'ọtụtụ ngwaahịa ụlọ ọrụ na azụmaahịa. Ọrụ ya n'ịkwalite arụmọrụ, nkwụsi ike na ịrụ ọrụ nke usoro dị iche iche na-eme ka ọ dị mkpa n'ofe akụkụ dị iche iche. Ka ụlọ ọrụ na-aga n'ihu na-emepụta ihe ọhụrụ, a na-atụ anya ka a na-achọ HPMC ga-adịgide adịgide, na-ebute ọganihu n'ihu na ụzọ mmepụta ya na ngwa ya.
