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

(Hydroxypropyl)methyl cellulose, e lauiloa foi i lona faapuupuuga HPMC poʻo lona CAS numera 9004-65-3, o se ether cellulose e maua mai le cellulose masani. O se polymer semi-synthetic lea e masani ona faʻaaogaina i pisinisi eseese ona o ona uiga faʻapitoa ma agavaʻa. O se va'aiga toto'a lea i lenei fa'apotopotoga:

Fauga ma Meatotino:
1 Fa'atulagaga: HPMC o lo'o fa'apipi'iina e ala i le suiga o vaila'au o le cellulose, lea o lo'o fa'afeiloa'i uma ai vaega o le methyl (-CH3) ma le hydroxypropyl (-CH2CHOHCH3) i luga ole ponaivi o le cellulose.
2 Degree of Substitution (DS): O le tikeri o le suitulaga e faasino i le averesi o numera o vaega e suitulaga i le kulukose i le filifili cellulose. E fuafua ai meatotino a le HPMC, e pei o le solubility, viscosity, ma le mafai ona fai ata.
3 Meatotino: HPMC o loʻo faʻaalia meatotino e pei o le mafiafia, faʻamauina o le vai, faʻavae ata, ma gaioiga i luga. E mafai ona fetuutuunai meatotino e ala i le puleaina o le DS i le taimi o le fa'asologa.

Gaosiga:
1.Cellulose Sourcing: Cellulose, o mea muamua mo le HPMC, e maua mai punaoa faʻafouina e pei o le pulu laupapa poʻo le cotton.
Etherification: O le cellulose e faʻafefeteina, lea e tali atu ai i le propylene oxide e faʻafeiloaʻi ai vaega hydroxypropyl ona sosoo ai lea ma le methyl chloride e faʻaopoopo ai vaega methyl.
2.Purification: O le cellulose ua suia e faʻamamaina e aveese ai mea leaga ma mea faʻatau, e mafua ai le oloa mulimuli a le HPMC.
Talosaga:
3.Construction Industry: O le HPMC e faʻaaogaina lautele i mea faufale e pei o sima faʻavae sima, faʻapipiʻi, ma faʻapipiʻi faʻapipiʻi e faʻaleleia ai galuega, faʻamauina o le vai, ma faʻapipiʻi.
4.Pharmaceuticals: E galue o se fusifusia, mafiafia, ata tifaga muamua, ma faʻamautu i vailaʻau faʻamaʻi e aofia ai papa, capsules, fofo ophthalmic, ma kulimi pito i luga.
5. Food Industry: O le HPMC e galue e pei o se mafiafia, faʻamautu, ma emulsifier i meaʻai eseese e pei o sosi, ofu, aisa kulimi, ma mea tao tao.
6. Cosmetics ma le Tausiga a le Tagata Lava Ia: I totonu o mea teuteu ma mea e teu ai le tagata lava ia, o le HPMC e faʻaaogaina e avea o se mafiafia, faʻamautu le sui, ata tifaga muamua, ma le susu i kulimi, lotions, shampoos, ma gels.
7.Paints and Coatings: E faʻaleleia ai le viscosity, sag resistance, ma mea faʻapipiʻi ata o vali faʻavae vai, faʻapipiʻi, ma ufiufi.
Fa'ai'uga:
(Hydroxypropyl)methyl cellulose, faʻatasi ai ma le tele o faʻaoga eseese ma mea aoga, o se mea taua tele i le tele o mea tau pisinisi ma pisinisi. O lana matafaioi i le faʻaleleia o le faʻatinoga, faʻamautu, ma le faʻatinoina o faʻatulagaga eseese e matua taua ai i le tele o vaega. A'o fa'aauau pea le fa'afouina o alamanuia, o le mana'oga mo le HPMC e fa'amoemoe e fa'aauau pea, ma fa'ateleina le fa'agasolo i luma i ana gaosiga ma fa'aoga.
