Hydroxypropyl Methylcellulose (HPMC)

O le Hydroxypropyl Methyl Cellulose e masani ona ta'ua o le Hypromellose, HPMC, o se ether cellulose non-ionic e maua mai i polymers fa'anatura e pei o le cotton fa'amamaina po'o le pulu laupapa e ala i se faasologa o vailaʻau. E tu'u mai e pei o se pauta pa'epa'e e leai se manogi, e le o'ona, ma e leai se tofo. O lenei vailaʻau e faʻafefeteina i totonu o vai vevela ma vai malulu, faʻatupuina se fofo viscous manino faʻatasi ai ma le tele o mea eseese, e matua sailia ai mo faʻaoga eseese.

O le HPMC o loʻo faʻaalia uiga faʻapitoa e pei o le mafiafia sili ona lelei, fusifusia, faʻasalalau, emulsifying, faʻapipiʻi ata, faʻamalolo, faʻafefe, gelling, faʻaogaina i luga, taofi vai, ma le puipuia o mea colloid. O lona fa'aogaina lautele e fa'atatau i alamanuia e aofia ai faufale, vaila'au, mea'ai, PVC, ceramics, ma mea tau tausiga a le tagata lava ia/fale.

I totonu o le vaega faufale, o le HPMC e avea o se mea e faʻafefeteina mo paluga faʻafefiloi faʻamago, faʻapipiʻi taʻavale, vali faʻavae vai, putty puipui, ma faʻasologa o sima faʻamaʻaina vevela. E le gata i lea, e maua ai le faʻaaogaina e avea o se vailaʻau faʻapitoa ma meaʻai, e saofagā i le gaosiga o PVC, ceramics, ma detergents. O le HPMC ose mea masani fo'i i 'ie, mea tau tausiga a le tagata lava ia, ma mea tau tausiga ile fale.

O le a le mea e fa'aoga ai le Hydroxypropyl Methylcellulose?

fa'amatalaga2

O le Hydroxypropyl Methylcellulose (HPMC) o se polymer sili ona lelei ma le tele o faʻaoga i totonu o pisinisi eseese. O ona uiga fa'apitoa e fa'atauaina i fa'atulagaga eseese. O nisi nei o fa'aoga masani ole Hydroxypropyl Methylcellulose:

O le a le tulaga lautele o le HPMC?

fa'amatalaga2

O le Hydroxypropyl Methylcellulose (HPMC) o se mea e maua mai i le cellulose ma le tele o mea totino e faʻaaogaina i pisinisi eseese. O meatotino masani nei a le HPMC:

Fa'atonuga vaila'au:

O le HPMC o se polymer semi-synthetic e maua mai i le cellulose, o se polymer masani o loʻo maua i puipui sela o laʻau.

O le fa'asologa o vaila'au o le HPMC e aofia ai vaega hydroxypropyl ma methyl o lo'o fa'apipi'i i le ivi o le cellulose.

Solubility:

O le HPMC e solu i le vai, e fai ai se vaifofo manino, lea e faigofie ai ona tu'u i totonu o vai.

Viscosity:

O se tasi o mea taua o le HPMC o lona gafatia e suia le viscosity. E mafai ona maua ai le mafiafia i vaifofo ma faʻavae, fesoasoani i le faʻaleleia atili o le fausaga ma le galue.

Ata-Fausia:

O le HPMC o lo'o iai ni mea e fai ai ata, lea e fa'aoga ai i fa'aoga e mana'omia ai le fa'atupuina o se ata e puipuia pe fa'atasi.

Su'ega vevela:

E fa'aalia e le HPMC le fa'a'ele'ele vevela, o lona uiga e fa'ateleina lona viscosity i le vevela. O lenei mea totino e masani ona faʻaaogaina i faʻatonuga faʻamalolo faʻasaina.

Gaoioiga i luga:

E mafai e le HPMC ona iai ni mea e pei o le surfactant, fa'aleleia le emulsification ma le fa'asalalauina i nisi fa'atulagaga.

Maumau:

E fesoasoani le HPMC i le mautu o taofiga, emulsions, ma isi faiga e ala i le puipuia o le faʻamautu poʻo le vavaeeseina.

Taofi Suavai:

E iai le malosi ole HPMC e fa'atumauina ai le vai, ma fa'atauaina i fa'aoga e mana'omia ai le fa'atumauina o le susu, e pei o mea faufale.

pipii:

I alamanuia eseese, HPMC faʻaleleia le pipii, pe i mea faufale e pei o sima poʻo i totonu o paʻu ma faʻapipiʻi.

Ole malosi ole vaila'au:

O le HPMC o lo'o fa'ainisinia, o lona uiga e le tali atu i isi vaega i le fa'atulagaina, fa'amautinoa le mautu ma le fetaui ma le tele o meafaitino.

pH maaleale:

O meatotino a le HPMC e mafai ona a'afia i le pH o le fofo po'o le fa'atulagaina. E masani ona mautu i luga o le lautele o le pH.

Maumau o le vevela:

O le HPMC e manatu e mafai ona fa'aleagaina, lea e mafai ona aoga i nisi o fa'aoga tau si'osi'omaga ma gafataulimaina.

O nei meatotino lautele e avea ai le HPMC ma polymer e sili ona lelei ma faʻaaogaina i alamanuia e pei o vailaʻau, faufale, meaʻai, mea teuteu, ma isi mea. O lona agava'a e fa'aleleia ai le rheological ma galuega fa'atino o mea fa'atatau e fesoasoani i lona fa'aogaina lautele.
