  3. O le le mautonu ma le fufuluina: O le mafuaʻaga o oloa e le faailogaina e aveese le sili atu a Alkali ona fufulu lea e aveʻese mai-oloa ma le mama.
  4. Faʻamamago ma olo: O le Heandscus HPMC e faʻamago ma le eleele i se lelei paʻu talafeagai mo ni aʻoaʻoga eseese.

4. Vasega ma faamatalaga:

O loʻo avanoa HPMC i le tele o vasega ma faʻamatalaga e faʻamalieina ai manaʻoga faʻapitoa o pisinisi eseese ma talosaga. E aofia ai suiga i VeriCosives, vaega tuʻufaʻatasi, faʻailoga o le suia o le suia, ma le siʻitia o le vevela. O ata masani o HPMC e aofia ai:

  • Tranchard Viscosty Grades (eg, 4000 CPS, 6000 CPS)
  • Maualuga videcosty Vades (eg, 15000 CPS, 20000 CPS)
  • Maualalo talitane vasega (eg, 1000 cps, 2000 cps)
  • Faʻataʻitaʻiga faʻapitoa mo faʻapitoa talosaga (eg, faʻaauau le tatalaina, pulea le tatalaina)

5. Talosaga o HPMC:

Na mauaina e HPMC le lautele o le faʻaaogaina i nisi o pisinisi ona o meatotino autu ma le talafeagai ma isi mea. O nisi o talosaga autu a le HPMC e aofia ai:

a. O le Alamanuiaga a le Pharmacouctical:

  • Laulau ma capsule ofu
  • Puleaina o le Tatala Faatulagaina
  • Fusi ma le fiafia i le laulau
  • Ophthalmic fofo ma faaletonu
  • O faʻamatalaga pito i luga e pei o kulimi ma suauʻu

e. Faletupe Fale:

  • Sima ma gypsum-faʻavae oloa (eg, mortars, plasters)
  • Tile Ageshiest ma Houghts
  • O le faʻalumaina o fafo ma le faʻamaeʻaina o faiga (Eif)
  • Lava-Loinging Manaoga
  • Vai-faavae vali ma ofutino

i. Alamanuia Meafaigaluega:

  • Mafiafia ma le faʻamalosiʻau o le sooupu i oloa taumafa
  • EMULSSIFER MA LE SITAVE AGENTER I Sasus ma ofu
  • O meaʻai o meaʻai
  • Gluten-saoloto fua ma confectonery

o e. Tausiga faaletagata lava ia ma cosmetics:

  • Thonicer ma Sypeing Socent i mea faatauga ma kulimi
  • Brader ma ata tifaga-muamua i fulufulu ava mamafa
  • Puleaina o le tatalaina i le palu pepa
  • Mata mata ma fesootai e lesi

6. Penefiti o le faaaogaina HPMC:

O le faʻaaogaina o le HPMC e ofoina atu ai le tele o penefiti i atunuʻu eseese:

  • Faaleleia le faatinoga oloa ma uiga lelei
  • Faʻalauteleina le faʻatulagaina o fetuutuunai ma le mautu
  • Faʻalautele le ola o le olaga ma faʻaititia le سرو spo
  • Faʻalauteleina le faʻagasologa le lelei ma le tau-lelei
  • Usitaia le tulafono faʻatonutonu manaʻoga ma tulaga saogalemu saogalemu
  • Siosiomaga faauo ma bicompauble

7. O mea le lumanaʻi ma vaʻaiga i fafo:

O le manaʻoga mo HPMC o loʻo fuafua e faifai pea, o loʻo ave aʻe i vaega e pei tele o le galueaina, atinae eseese, ma talosaga mo oloa faʻa-fai pisinisi. O taumafaiga faifai pea o suʻesuʻega ma atinae o loʻo masani ai i le auiliiliga o tulafono HPMC, e faʻalautele ana apamefo, ma faʻaleleia auala e faʻamalieina ai e tele manaʻoga o maketi.

8. Faaiuga:

Hydroxypropyl methylcelsulose (HPMC) o se vaega o polymer ma eseese fuainumera i luga o le tele o pisinisi. O lona tulaga ese, pei o le vai fulufulu, foliga ata tifaga, ma mafiafia o meatotino, faʻatupu le fausiaina o vailaʻau, meaʻai, tausiga patino, ma gaioiga a le tagata lava ia. A o faafaigaluegaina faasolosolo ma maketi maketi, o le HPMC o loʻo faamoemoe e taʻalo ai se suiga taua i le lumanaʻi o le tele o pisinisi.
