Hydroxyethyl Cellulose (HEC) o se faʻaoga masani faʻamalosi, emulsifier ma stabilizer, faʻaaogaina lautele i paʻu, cosmetics, detergents, mea fau fale ma isi fanua. O lona fa'aogaina fua faatatau e masani lava ona fuafuaina e tusa ai ma le fa'ata'ita'iga fa'apitoa o le fa'aogaina ma le fa'atulagaina o mana'oga.
1. Alamanuia fa'apipi'i
I totonu o faʻamau faʻavae vai, o le hydroxyethyl cellulose e masani ona faʻaaogaina e avea o se mafiafia ma faʻamautu le sui e fesoasoani e fetuunai le viscosity ma le rheology o le ufiufi. E masani lava, o le fua faatatau faʻaaogaina e 0.1% i le 2.0% (fuafuaga mamafa). Ole fua faʻatatau faʻapitoa e faʻalagolago ile ituaiga o faʻapipiʻi, mea manaʻomia o le rheological ma le tuʻufaʻatasia o isi mea.
2. Mea teuteu ma mea tau tausiga a le tagata lava ia
I cosmetics, hydroxyethyl cellulose o loʻo faʻaaogaina e avea o se mafiafia ma faʻamautu e fesoasoani e faʻaleleia le faʻaogaina ma le faʻaogaina o le gaioiga o le oloa. Ole fua fa'aoga masani ole 0.1% ile 1.0%. Mo se faʻataʻitaʻiga, i le shampoo, faʻamama mata, lotion ma gel, HEC e mafai ona maua ai le paʻi lelei ma le mautu.
3. Fa'amama ma fa'amama
I totonu o vai mama, hydroxyethyl cellulose e faʻaaogaina e fetuunai ai le viscosity ma le faʻamalolo o le oloa ma puipuia ai le faʻafefe o vaega mautu. Ole fua fa'aoga masani e 0.2% ile 1.0%. Ole aofa'i ole HEC o lo'o fa'aaogaina i ituaiga eseese o mea fa'amama e ono eseese.
4. Mea faufale
I totonu o mea faufale, e pei o le sima slurry, gypsum, tile adhesives, ma isi mea, hydroxyethyl cellulose e faʻaaogaina e fai ma vai faʻamau ma mafiafia. E masani lava, o le fua faatatau faʻaaogaina e 0.1% i le 0.5%. E mafai e le HEC ona faʻaleleia le fausiaina o meafaitino, faʻalautele le taimi faʻagaioiga, ma faʻaleleia le meatotino anti-sagging.
5. Isi talosaga
O le hydroxyethyl cellulose o loʻo faʻaaogaina lautele i isi matāʻupu, e pei o meaʻai ma vailaʻau. Ole fua ole fa'aoga e masani lava ona fetu'una'i e tusa ai ma manaoga fa'apitoa ole talosaga. Mo se faʻataʻitaʻiga, i totonu o pisinisi taumafa, HEC e mafai ona faʻaaogaina e avea o se mafiafia, faʻamautu ma emulsifier, ma o lona faʻaaogaina e masani lava ona maualalo.
Fa'aeteetega
A faʻaaoga le hydroxyethyl cellulose, e tatau ona e gauai atu i vaega nei:
Auala faʻaumatia: O le solubility o le HEC e aʻafia i le vevela, tau pH ma tulaga faʻafefe. E masani ona manaʻomia le faʻaopopo lemu i le vai ma faʻafefeteina lelei.
Feso'ota'iga fua fa'atatau: E ono a'afia ai le fa'atinoga o le HEC o mea fa'atatau e 'ese'ese, o lea e mana'omia ai su'esu'ega fa'atatau i le taimi o le fa'atupuina o le fa'asologa.
Pulea viscosity: E tusa ai ma manaoga o le oloa mulimuli, filifili le ituaiga HEC talafeagai ma fua e ausia ai le viscosity manaʻomia.
Ole fua faatatau ole fa'aogaina ole hydroxyethyl cellulose ose fa'atatau fetuutuunai e mana'omia ona fetu'una'i e tusa ai ma le fa'aogaina ma le fa'atulagaina. O le malamalama i le faʻatinoga o le HEC i faʻaoga eseese e mafai ona fesoasoani e faʻamalieina le faʻatinoga o oloa ma le lelei.
