Faʻaleleia le faʻatinoga o mea faufale - hydroxypropyl methylcellulose

Hydroxypropyl methylcellulose (HPMC mo pupuu) o se ether fefiloi taua, o se polymer non-ionic vai-soluble, ma e masani ona faaaogaina i meaai, vailaau, alamanuia kemikolo i aso taitasi, ufiufi, polymerization tali ma le fausiaina o se faʻamalologa faʻamavae, mafiafia, emulsifying, stabilizing ma adhesives, ma isi, ma o loʻo i ai se va tele i le maketi i totonu o le atunuʻu.

Hydroxypropyl methylcellulose o loʻo faʻaaogaina lautele i le fale faufale e avea o se sui fai ata tifaga, fusi, dispersant, stabilizer, mafiafia, faʻaleleia vai, ma isi, ma ua avea ma se fetu oloa ua tosina atu i ai talu ona faʻalauiloaina i luga o le laina.

Hydroxypropylmethylcellulose

Igilisi igoa atoa: Hydroxypropyl Methyl Cellulose Fa'apuupuuga Igilisi: HPMC

Talu ai ona o le HPMC o loʻo i ai mea sili ona lelei e pei o le mafiafia, emulsification, ata tifaga, colloid puipuia, faʻamauina o le susu, faʻapipiʻi, tetee enzyme ma le gasegase metabolic, e faʻaaogaina lautele i coatings, polymerization reactions, mea fau fale, gaosiga o suauʻu, textiles, meaʻai, vailaʻau, Osimea fa'aoga i aso uma, masini fa'aeletonika ma fatu fa'ato'aga ma isi matagaluega.

mea faufale

I mea faufale, HPMC poʻo le MC e masani ona faʻaopoopo i le sima, sima, ma le sima e faʻaleleia ai le fausiaina ma le faʻamauina o vai.

E mafai ona faʻaaogaina e pei o:

1). Fa'apipi'i ma so'o fa'apipi'i mo lipine fa'apipi'i fa'avae gypsum;

2). Fa'amauina o piliki fa'avae sima, ma'a ma fa'avae;

3). stucco fa'avae laupapa;

4). Sima fa'avae fausaga fa'apipi'i;

5). I le fua o le vali ma le vali vali.

Fa'apipi'i mo ma'a sima

HPMC 15.3 vaega

Perlite 19.1 vaega

Fatty amides ma cyclic thio compounds 2.0 vaega

Omea 95.4 vaega

Fa'amasima silica (22μ) 420 vaega

450.4 vaega ole vai

Fa'aaogaina i le sima e fa'apipi'i i piliki, ta'ele, ma'a po'o sima:

HPMC (fa'asalalau tikeri 1.3) 0.3 vaega

Cattelan sima 100 vaega

Silica oneone 50 vaega

50 vaega o le vai

Fa'aaogaina e fai ma mea fa'apipi'i fau sima maualuga:

Cattelan sima 100 vaega

Asbestos 5 vaega

Polyvinyl alcohol toe faaleleia 1 vaega

Calcium silicate 15 vaega

Omea 0.5 vaega

32 vaega o le vai

HPMC 0.8 vaega

Alamanuia vali

I totonu o le fale vali, HPMC e tele lava ina faʻaaogaina i le latex vali ma vai-soluble resin vaega vali e avea o se sui fai ata tifaga, mafiafia, emulsifier ma stabilizer.

Fa'agata le Polymerization o le PVC

O le fanua e sili ona tele le taumafaina o oloa HPMC i loʻu atunuu o le faʻamalologa polymerization o vinyl chloride. I le faʻamalologa polymerization o le vinyl chloride, o le faʻasalalauga faʻapitoa e aʻafia tonu ai le lelei o le oloa PVC resin ma lona gaosiga ma oloa; e mafai ona faʻaleleia le faʻamautuina o le vevela o le resin ma faʻatautaia le tufatufaina o le tele o vaega (o lona uiga, fetuunai le maualuga o le PVC). Ole aofa'i ole HPMC e maua ile 0.025%~0.03 ole PVC.

O le PVC resin ua saunia e le HPMC maualuga, faʻaopoopo i le faʻamautinoaina o le faʻatinoga e fetaui ma tulaga faʻale-atunuu, e iai foʻi mea lelei faʻaletino, uiga sili ona lelei ma le faʻafefeteina lelei o amio rheological.

isi pisinisi

O isi pisinisi e tele lava ina aofia ai mea teuteu, gaosiga o suauʻu, vailaʻau faʻamama, sima fale ma isi pisinisi.

solu vai

HPMC o se tasi o polymers vai soluble, ma lona solubility vai e fesootai ma le anotusi o le vaega methoxyl. Pe a maualalo le anotusi o le vaega o le methoxyl, e mafai ona faʻamavaeina i le alkali malosi ma e leai se mea e faʻaogaina ai le thermodynamic. Faatasi ai ma le faateleina o le methoxyl anotusi, e sili atu ona maaleale i le fulafula vai ma soluble i dilute alkali ma vaivai alkali. A oʻo i le methoxyl mea e sili atu i le 38C, e mafai ona faʻamavaeina i le vai, ma e mafai foi ona faʻamavaeina i hydrocarbons halogenated. Afai e fa'aopoopo le vaila'au fa'avaitaimi i le HPMC, o le a vave ona ta'ape le HPMC i le vai e aunoa ma le fa'atupuina o ni mea e fa'afefeteina. O lenei mea e mafua ona o le mea moni o le acid periodic o loʻo i ai vaega dihydroxyl i le tulaga masani i luga o le glycogen faʻasalalau.
