Vasega faufale HEMC

Fausia vasega HEMC Hydroxyethyl Methyl Cellulose ua lauiloa o le Methyl Hydroxyethyl Cellulose(MHEC), o le pa'epa'e pa'epa'e po'o le pa'epa'e pa'epa'e, leai se manogi ma leai se tofo, solu i vai vevela ma vai malulu. Fausia vasega HEMC e mafai ona faʻaaogaina e pei o le sima, gypsum, lime gelling agent, vai faʻamauina sui, o se faʻafefiloi sili ona lelei mo mea faufale paʻu.

Fa'atonuga mole:

Mea e Fa'atau ai:

1. Fa'aaliga: HEMC o le pa'epa'e po'o le toetoe lava pa'epa'e; leai se manogi ma leai se tofo.

2. Solubility: O le ituaiga H i le HEMC e mafai ona faʻamavaeina i le vai i lalo ifo o le 60 ℃, ma le ituaiga L e mafai ona faʻamavaeina i le vai malulu. HEMC e tutusa ma le HPMC ma e le mafai ona solu i le tele o solvents organic. A maeʻa togafitiga i luga, HEMC faʻasalalau i le vai malulu e aunoa ma le faʻapipiʻiina ma solo lemu, ae mafai ona vave faʻamavaeina e ala i le fetuunai o lona tau PH i le 8-10.

3. Faʻamautu le tau o le PH: O le viscosity e suia itiiti i totonu o le va o le 2-12, ma o le viscosity e faʻaleagaina i tua atu o lenei laina.

4. Fineness: o le pasi fua faatatau o 80 mata o le 100%; le fua faatatau o le 100 mata o le ≥99.5%.

5. Lave fa'apitoa sese: 0.27-0.60g/cm3.

6. O le vevela vevela e sili atu i le 200 ℃, ma e amata ona mu ile 360 ​​℃.

7. HEMC o loʻo iai le mafiafia taua, faʻamautu faʻamalolo, faʻasalalau, faʻatasi, faʻaogaina, taofi vai ma isi uiga.

8. Ona o le oloa o loʻo i ai le vaega hydroxyethyl, o le vevela gel o le oloa e oʻo atu i le 60-90 ℃. E le gata i lea, o le vaega o le hydroxyethyl e maualuga le hydrophilicity, lea e lelei ai foi le fua faatatau o oloa. Aemaise lava i le fausiaina o le vevela ma le maualuga o le vevela i le taumafanafana, o le HEMC o loʻo i ai le maualuga o le faʻamauina o le vai nai lo le methyl cellulose o le viscosity tutusa, ma o le vai faʻamauina e le itiiti ifo i le 85%.

Oloa Vasega   

Taua

I le avea ai o se sui malosi i luga, o le hydroxyethyl methyl cellulose HEMC o loʻo i ai uiga nei i le faʻaopoopoga i le mafiafia, faʻamalolo, faʻapipiʻi, emulsifying, faʻapipiʻi ata, faʻasalalau, taofi vai ma tuʻuina atu colloids puipuia:

(1) Hydroxyethyl methyl cellulose HEMC e mafai ona solu i le vai vevela poʻo le malulu, e maua ai le tele o le solubility ma uiga viscosity, o lona uiga, gelation e le vevela;

(2) Hydroxyethyl methyl cellulose HEMC e mafai ona ola faʻatasi ma le tele o isi polymers solu vai-soluble, surfactants, ma masima, ma o se mafiafia sili ona lelei mo fofo eletise eletise maualuga;

(3) O le HEMC e sili atu le malosi o le taofiofia o le vai nai lo le methyl cellulose, ma o lona viscosity mautu, dispersibility, ma le mildew tetee e sili atu le malosi nai lo le hydroxyethyl cellulose.

Auala sauniuni fofo

(1) Fa'aopoopo se aofa'i o vai mama i le fagu;

(2) Fa'aopoopo le hydroxyethyl methyl cellulose HEMC i lalo o le fa'aoso maualalo, ma fa'aoso se'ia o'o ina solo uma le hydroxyethyl methyl cellulose;

(3) I le vaʻai atu i a matou faʻamatalaga faʻataʻitaʻiga faʻapitoa, e matua fautuaina lava e faʻaopoopo pe a uma ona faʻapipiʻi le polymer emulsion (ie, hydroxyethyl methyl cellulose HEMC ua muamua faʻafefiloi ma le ethylene glycol poʻo le propylene glycol).

Ustausaga

I mea tau fale gaosi oloa, o le faufale HEMC e talafeagai mo le faʻapipiʻi tile, sima sima, sima faʻafefiloi mago, faʻavasegaina o le tagata lava ia, gypsum plaster, vali latex, faʻapipiʻi mea fau fale, isi fanua faufale, suauʻu suauʻu, oloa tausiga a le tagata lava ia, faʻamamā, ma isi. , e masani ona faʻaaogaina e pei o mea mafiafia, mea e puipuia ai, faʻapipiʻi, faʻamautu, ma faʻamalo le tumau e mafai foi ona faʻaaogaina e pei o gels hydrophilic, mea matrix, saunia matrix-type sustained-release sauniuniga, ma e mafai foi ona faʻaaogaina e avea ma faʻamautu i meaʻai, ma isi aafiaga. .

Packaging ma le teuina

(1) Faʻapipiʻi i totonu o pepa-palasitika faʻapipiʻi polyethylene taga poʻo pepa pepa, 25KG / taga;

(2) Taofi le ea e tafe i totonu o le mea e teu ai, aloese mai le susulu o le la, ma aloese mai mea e mafua ai le afi;

(3) Ona o le hydroxyethyl methyl cellulose HEMC e hygroscopic, e le tatau ona faʻaalia i le ea. O oloa e le'i fa'aaogaina e tatau ona fa'amaufa'ailoga ma teu, ma puipuia mai le susu.

20'FCL: 12Ton ma palletized, 13.5Ton e aunoa ma palletized.

40'FCL: 24Ton ma palletized, 28Ton e aunoa ma palletized.
