1. Properties na hydroxyethyl cellulose
Wannan samfurin fari ne ko haske rawaya mara wari da sauƙi mai gudana foda, 40 raga sieve rate ≥99%;zafin jiki mai laushi: 135-140 ° C;yawa na fili: 0.35-0.61g/ml;zafin jiki bazuwa: 205-210 ° C;Gudun ƙonawa Slower;daidaitaccen zafin jiki: 23 ° C;6% a 50% rh, 29% a 84% rh.
Yana da narkewa a cikin ruwan sanyi da ruwan zafi, kuma gabaɗaya baya narkewa a yawancin kaushi na halitta.Danko yana canzawa kadan a cikin kewayon ƙimar PH 2-12, amma danko yana raguwa fiye da wannan kewayon.
2. Muhimman kaddarorin
Kamar yadda ba-ionic surfactant,hydroxyethyl celluloseyana da kaddarorin masu zuwa ban da kauri, dakatarwa, ɗaure, iyo, shirya fim, tarwatsawa, riƙe ruwa da samar da colloid mai kariya:
1. HEC yana narkewa a cikin ruwan zafi ko ruwan sanyi, kuma baya tasowa a babban zafin jiki ko tafasa, wanda ya sa yana da nau'i mai yawa na solubility, halaye na danko da kuma rashin zafi.
2. Ba shi da ionic kuma yana iya zama tare da wasu nau'o'in nau'in polymers masu narkewa da ruwa, surfactants, da salts.Yana da kyau kwarai colloidal thickener ga high-natsuwa electrolyte mafita.
3. Ƙarfin ajiyar ruwa ya ninka sau biyu fiye da na methyl cellulose, kuma yana da mafi kyawun tsari.
4. Idan aka kwatanta da gane methyl cellulose da hydroxypropyl methyl cellulose, HEC yana da mafi munin dispersing ikon, amma mafi karfi m colloid ikon.
3. Amfani da hydroxyethyl cellulose
Kullum amfani da thickeners, m jamiái, adhesives, stabilizers da Additives ga shirye-shiryen na emulsion, jellies, man shafawa, lotions, ido cleansers, suppositories da Allunan, da kuma amfani da matsayin hydrophilic gels, kwarangwal kayan, Ana iya amfani da su shirya matrix- nau'in shirye-shiryen ɗorewa-saki, kuma ana iya amfani dashi azaman stabilizer a abinci.
