Aotelega o Atinae Maketi o Saina Hydroxypropyl Methylcellulose (HPMC) Alamanuia i le 2022

Hydroxypropyl methyl cellulose (HPMC) o se cellulose fefiloi ether ituaiga o lona gaosiga, fua ma le lelei ua vave ona faateleina i tausaga talu ai nei.Non-ionic cellulose fefiloi ether faia e isi faiga.

O le HPMC e lelei ona ta'ape, emulsifying, mafiafia, fa'atasi, fa'atumauina le vai ma mea e taofi ai pulu.E solu i le vai, ma e mafai foi ona solo i le ethanol ma le acetone i lalo ole 70%.HPMC faʻatasi ai ma fausaga faʻapitoa e mafai foi ona faʻamavae saʻo ile ethanol.HPMC e mafai ona faʻaaogaina lautele e pei o le faʻapipiʻiina o ata tifaga, faʻamalolo faʻamalolo lagolago ma faʻamau mo sauniuniga vailaʻau, ma e mafai foi ona faʻaaogaina lautele i petrochemicals, mea fau fale, ceramics, textiles, meaʻai, vailaʻau i aso uma e ala i le faʻaaogaina o lona mafiafia, faʻasalalau, emulsifying ma ata tifaga. meatotino., resin gaosia, vailaau, vali ma mea tau eletise ma isi fanua.

O le faagasologa o le gaosiga o le HPMC e mafai ona vaevaeina i ni vaega se lua: auala vaega kesi ma auala vaega vai.I le taimi nei, o atunuʻu atinaʻe e pei o Europa, Amerika ma Iapani o loʻo faʻaaogaina le tele o le gas-phase process, faʻaaogaina laupapa laupapa e pei o mea mata (o loʻo faʻaaogaina pulupulu e gaosia ai oloa maualuga-viscosity), alkalization ma etherification o loʻo faia i le tali tutusa. meafaigaluega, ma o le tali autu o se tali faalava.O le ulo o loʻo i ai se faʻalavelave faʻafefe faʻalava tutotonu ma se naifi faʻafefe lele e faʻapitoa mo le gaosiga o le cellulose ether, lea e mafai ona maua ai se faʻafefiloi lelei.

Fai mai le au suʻesuʻe o pisinisi mai Xinsijie, faatasi ai ma le faʻaauau pea o le tamaoaiga ma le faʻaauau pea o le faʻaleleia o le olaga o tagata, o le manaʻoga mo le hydroxypropyl methylcellulose o loʻo faʻaauau pea ona faʻatupulaia.Mo se taimi umi, o loʻo manaʻomia e loʻu atunuu hydroxypropyl methylcellulose maketi o loʻo faʻatumauina i le fanua o le fausiaina ma le ufiufi.Faatasi ai ma le faʻaauauina o le atinaʻeina o pisinisi i lalo, o le manaʻoga mo le hydroxypropyl methylcellulose i totonu o meaʻai ma vailaʻau ua amata ona faʻalauteleina vave.I le lumanaʻi, o le fausiaina, meaʻai ma falemaʻi falemaʻi o le a avea ma malosiaga taua mo le tuputupu aʻe o le maketi o le hydroxypropyl methylcellulose a loʻu atunuu.
