Babban amfani da bambance-bambancen hydroxypropyl methylcellulose HPMC da hydroxyethyl cellulose HEC

Carboxymethyl cellulose, hydroxypropyl methyl cellulose, da hydroxyethyl cellulose tare da masana'antu monosodium glutamate ana amfani da mafi girma adadin.Mafi wahalar bambance tsakanin waɗannan nau'ikan cellulose guda uku shine hydroxypropyl methylcellulose da hydroxyethyl cellulose.A ƙasa za mu bambanta waɗannan nau'ikan cellulose guda biyu ta hanyar amfani da aikinsu.

A matsayin surfactant ba ionic, hydroxyethyl cellulose yana da wadannan kaddarorin ban da ayyuka na dakatarwa, thickening, dispersing, iyo, bonding, film forming, ruwa riƙe da samar da colloid m:

1. HEC kanta ba ta da ionic kuma tana iya zama tare da nau'in nau'in nau'in polymers masu narkewa da ruwa, surfactants, da salts.Yana da kyakkyawan kauri na colloidal don mafita mai ƙunshe da babban adadin kuzari.

2. Idan aka kwatanta da gane methyl cellulose da hydroxypropyl methyl cellulose, da dispersing ikon HEC ne mafi muni, amma m colloid ikon ne mafi karfi.

3. Ƙarfin ajiyar ruwa ya ninka sau biyu fiye da na methyl cellulose, kuma yana da mafi kyawun tsari.

4. HEC yana narkewa a cikin ruwan zafi ko ruwan sanyi, kuma baya tasowa a yanayin zafi mai zafi ko tafasa, wanda ya sa ya sami nau'i mai yawa na solubility da danko, da kuma rashin zafi.

Amfani da HEC: gabaɗaya ana amfani dashi azaman mai kauri, wakili mai karewa, m, stabilizer da shirye-shiryen emulsion, jelly, maganin shafawa, ruwan shafa fuska, bayyanan ido.

Gabatarwar aikace-aikacen Hydroxypropyl methylcellulose (HPMC):

1. Coating masana'antu: Ana amfani da a matsayin thickener, dispersant da stabilizer a cikin shafi masana'antu, kuma yana da kyau dacewa a cikin ruwa ko kwayoyin kaushi.A matsayin mai cire fenti.

2. Masana'antar masana'anta: An yi amfani da shi sosai azaman mai ɗaure a cikin kera samfuran yumbu.

3. Wasu: Hakanan ana amfani da wannan samfurin a cikin fata, samfuran takarda, adana 'ya'yan itace da kayan lambu da masana'antar masaku, da sauransu.

4. Buga tawada: Ana amfani dashi azaman mai kauri, rarrabawa da daidaitawa a cikin masana'antar tawada, kuma yana da dacewa mai kyau a cikin ruwa ko abubuwan kaushi.

5. Filastik: ana amfani da shi azaman wakili na saki, softener, mai mai, da dai sauransu.

6. Polyvinyl chloride: Ana amfani dashi azaman mai rarrabawa a cikin samar da polyvinyl chloride, kuma shine babban mahimmin taimako don shirya PVC ta hanyar dakatar da polymerization.da

7. Masana'antar gine-gine: A matsayin wakili mai riƙe da ruwa da kuma mai dagewa na siminti yashi slurry, zai iya sa turmi ya zama mai famfo.A cikin plaster, gypsum, putty foda ko wasu kayan gini a matsayin mai ɗaure don inganta yadawa da tsawaita lokacin aiki.Ana iya amfani da shi azaman tayal na manna, marmara, kayan ado na filastik, ƙarfafa manna, kuma yana iya rage adadin siminti.Ayyukan riƙe ruwa na HPMC yana hana slurry daga fashe saboda bushewa da sauri bayan aikace-aikacen, kuma yana haɓaka ƙarfi bayan taurin.
