Hydroxypropylmethylcellulose (HPMC) o se polymer faia e ala i le suia o cellulose natura.O lo'o i ai le tele o fa'aoga fa'apisinisi i vaila'au, mea'ai, mea teuteu, ma faufale.O le HPMC o se ether cellulose nonnionic e faigofie ona solu i le vai ma e mafai ona fausia se vaifofo manino, viscous e tumau mautu i luga o le lautele o le pH.
O vaega ole HPMC e aofia ai:
1. Mauaina vai maualuga: E mafai e le HPMC ona mitiia le vai ma taofi i totonu, faʻaaogaina e avea o se mafiafia, emulsifier, ma faʻamautu i le tele o talosaga.
2. Mea lelei e fai ata tifaga: E mafai e le HPMC ona fausia ata manino ma le malosi faʻainisinia lelei.O lenei mea e mafai ai ona faʻaaogaina i le gaosiga o capsules, coatings ma isi oloa.
3. Gaoioiga maualuga i luga: HPMC o loʻo i ai mea faʻapitoa i luga ole laiga, faʻatagaina e faʻaaogaina e avea o se susū susū ma faʻasalalau.
4. Faʻamautu lelei vevela: HPMC e faʻamautu i le maualuga o le vevela ma e mafai ona faʻaaogaina i talosaga e manaʻomia ai lenei faʻatinoga.
5. Faʻapipiʻi lelei i luga o mea eseese: E mafai e le HPMC ona faʻapipiʻi i le tele o luga, e faʻaaogaina ai le gaosiga o mea faʻapipiʻi ma paʻu.
Le faʻaogaina o le HPMC i pisinisi eseese:
1. Vailaau: HPMC e masani ona faʻaaogaina i vailaʻau vailaʻau e pei o se fusifusia, faʻaleagaina, ma faʻatonuga viscosity.E maua i papa, capsules ma fa'asusu vai.
2. Mea'ai: E fa'aaogaina le HPMC e fai ma mafiafia, fa'amautu ma emulsifier i mea'ai.E mafai ona fa'aogaina i oloa e pei o aisakulimi, yogurt ma salati dressings.
3. Cosmetics: E masani ona faʻaaogaina le HPMC i mea teuteu e pei o se mafiafia, emulsifier, ma se sui fai ata.E mafai ona faʻaaogaina i oloa e pei o kulimi, lotions ma shampoos.
4. Fausiaina: O le HPMC o se elemene autu i le tele o mea faufale e pei o faʻapipiʻi taʻavale, faʻapipiʻi sima ma sima.E galue e pei o se vai e taofia ai le vai, faʻaleleia le faʻaogaina, ma maua ai le faʻapipiʻi lelei ma le faʻaitiitia o le pulea.
HPMC alamanuia faasinomaga fua faatatau:
1. Faʻamauina o le vai: Ole fua ole vai ole HPMC o se faʻamaufaʻailoga taua e fuafua ai lona aoga e pei o se mafiafia ma faʻapipiʻi.O le fanua o loʻo i ai fua faʻatatau o alamanuia o le 80-100%.
2. Viscosity: Viscosity o se vaega autu i le filifilia o le HPMC mo talosaga eseese.Alamanuia fa'atatau fua faatatau mo viscosity tulaga mai le 5,000 i le 150,000 mPa.s.
3. Methoxyl group content: O le methoxyl group content o le HPMC e a'afia ai lona solubility, viscosity ma bioavailability.Ole fua faatatau ole alamanuia mo mea e maua ile methoxy ile va ole 19% ma le 30%.
4. Hydroxypropyl anotusi: O le hydroxypropyl anotusi e aafia ai le solubility ma le viscosity o le HPMC.Ole fua faatatau ole alamanuia mo mea e maua ile hydroxypropyl ile va ole 4% ma le 12%.
O le HPMC o se polymer faʻapitoa ma le tele o faʻaoga faʻapisinisi.O ona uiga tulaga ese e talafeagai mo le faʻaaogaina i vailaʻau, meaʻai, mea teuteu ma le fausiaina.Ole fua faatatau ole alamanuia mo ta'aloga eseese e fesoasoani ile filifilia ole vasega talafeagai ole HPMC mo se talosaga fa'apitoa.
