Hydroxye ether (HEC) shi ne wanda ba-ionic ruwa -soluble polymer samu daga cellulose.Yawancin lokaci ana amfani da shi a masana'antu daban-daban, kamar magunguna, kayan shafawa da abinci, azaman masu kauri da gel.Magance HEC tsari ne na kai tsaye, amma yana buƙatar la'akari da abubuwa kamar zazzabi, pH da motsawa.
Bayanan martaba:
Hydroxye ethyl cellulose (HEC) wani abu ne na cellulose wanda aka haɗa ta hanyar amsawa tare da oxide.A dauki gabatar da hydroxyl kungiyar a cikin babban sarkar na cellulose, game da shi ya ba da polymer zuwa ruwa -soluble.HEC yana da ikon samar da gel na gaskiya da kwanciyar hankali a cikin maganin aquare, yana mai da shi ɓangaren multifunctional tsakanin aikace-aikace da yawa.
Abubuwan da ke shafar rushewar HEC:
1. Zazzabi:
HEC narkewar dogaro zafin jiki.Yawan zafin jiki yakan haifar da rushewa da sauri.
Yawancin lokaci ana amfani da ruwan dumi don inganta tsarin narkewa.Duk da haka, ya kamata a guji matsanancin zafi don hana lalacewa.
2. PH matakin:
HEC yana da kwanciyar hankali a cikin kewayon pH mai faɗi, yawanci tsakanin 2 da 12. Daidaita ƙimar pH na maganin zai iya rinjayar ƙimar rushewa.
Mafi kyawun rushewa yawanci shine zaɓi na farko don zama ɗan ƙaramin alkaline pH yanayin.
3. Tausayi:
Dama ko motsawa don haɓaka rushewar HEC.Haɗe-haɗe mai laushi yana taimakawa polymer a ko'ina a cikin sauran ƙarfi ko'ina don hana tubalan.
Juyawa injina ko amfani da mahaɗar maganadisu ya zama ruwan dare a cikin yanayin dakin gwaje-gwaje.
4. Zabin mai narkewa:
HEC yana narkewa cikin ruwa don samar da bayani mai haske.Zaɓin ingancin ruwa (distillation, exfoliating) zai iya rinjayar rushewa.
Nisantar ƙazanta a cikin abubuwan kaushi yana da mahimmanci don hana kowane mummunan halayen.
Hanyar narkar da HEC:
1. Narkar da ruwan zafi:
Yi zafi da ruwan zuwa zafin jiki sama da zafin dakin, amma ƙasa da ƙarancin zafin jiki na HEC.
Kullum tana motsa HEC a hankali ƙara zuwa ruwa don hana tubalan.
Rike zafin jiki har sai an narkar da shi gaba daya.
2. Ruwan sanyi yana narkewa:
Kodayake yana da hankali fiye da ruwan zafi, ruwan sanyi zai iya narkar da HEC yadda ya kamata.
A hankali ƙara HEC zuwa ruwan sanyi kuma a haɗa cakuda.
Rarraba da narkar da isasshen lokaci don polymers.
3. Daidaita PH:
Dangane da aikace-aikacen, ana amfani da pH na ruwa don daidaita pH na ruwa zuwa matakin da ake buƙata.
Kula da canje-canjen ƙimar pH yayin rushewar don tabbatar da kwanciyar hankali.
4. Fasaha ta motsa jiki:
Yi amfani da injin motsa jiki, motsawar maganadisu, ko haɗa wasu nau'i mai laushi don taimakawa HEC tarwatsa.
Ci gaba da motsawa har sai maganin ya kasance daidai.
5. Haɗin hanya:
Haɗin zafi, daidaitawar pH da motsawa ana amfani dashi don inganta narkewa.
Daban-daban sigogi na gwajin don cimma ƙimar rushewar da ake buƙata.
warware matsalar:
1. Toshewa:
Idan toshe ya faru, don Allah a rage karuwa a cikin sauran ƙarfi kuma ƙara motsawar HEC.
Rushe kowane shingen rukuni da hannu, ko daidaita saurin motsawa.
2. Rashin isasshen narkewa:
Idan ba a narkar da polymer gaba ɗaya ba, duba ƙazanta a cikin sauran ƙarfi ko rashin isasshen motsawa.
Yi la'akari da daidaita yanayin zafi ko amfani da hanyoyi daban-daban na narkewa.
Solubbing HEC ya ƙunshi abubuwa daban-daban, gami da zazzabi, pH, da motsawa.Fahimtar halaye na HEC da takamaiman buƙatun aikace-aikacen suna da mahimmanci don cimma mafi kyawun rushewa.Gwaje-gwajen gwaji da kulawa da hankali zasu taimaka wajen magance duk wata matsala mai yiwuwa.Koyaushe bi jagorar tsaro kuma tuntuɓi teburin bayanan fasaha don samun takamaiman umarnin da masana'anta suka bayar.
