Hydroxyethyl cellulose(HEC) ndi polima yopanda madzi, yosungunuka m'madzi. Ndi ufa wonyezimira wonyezimira, wopanda madzi ndipo umapangidwa ndikuchitapo kanthu ethylene oxide ndi alkali-cellulose. HEC imagwiritsa ntchito m'mafakitale odzola komanso osamalira anthu ngati gelling ndi thickening agent. M'zamankhwala, cellulose imagwiritsidwa ntchito ngati adsorbent, glidant, solvent mankhwala, ndi kuyimitsa wothandizira. Amapezekanso m'zinthu zoyeretsera m'nyumba.
Hydroxyethyl cellulosendi chochokera ku polysaccharide yokhala ndi makulidwe a gel, emulsifying, kupanga kuwira, kusunga madzi komanso kukhazikika. Amagwiritsidwa ntchito ngati chinthu chofunikira kwambiri pakuyeretsa m'nyumba zambiri, mafuta odzola ndi zodzoladzola chifukwa chosakhala ndi ionic komanso sungunuka m'madzi. Nthawi zambiri amagwiritsidwa ntchito ngati chophatikizira chamankhwala opangira maso monga njira zopangira misozi ndi adjunct adjunct mumipangidwe yamankhwala apakhungu kuti athandizire kutumiza mankhwala okhala ndi hydrophobic.
Kodi hydroxyethyl cellulose ndi yachilengedwe?
Hydroxyethyl cellulose ndi imodzi mwazinthu zoterezi zomwe ndi 100% zachilengedwe komanso zamasamba, zomwe zimachokera ku cellulose, yomwe ndi imodzi mwazinthu zomwe timazidziwa.
Kugwiritsa ntchito hydroxyethyl cellulose:
Hydroxyethyl celluloseali ndi ntchito zambiri: Pamakampani opanga utoto, Hydroxyethyl Cellulose imatha kupereka utoto wa latex makamaka utoto wapamwamba wa PVA wokhala ndi ntchito yabwino yokutira. Pamene utoto uli wandiweyani phala, palibe flocculation idzachitika. Ma cellulose a Hydroxyethyl ali ndi kukhuthala kwakukulu. Itha kuchepetsa mlingo, kupangitsa kuti utoto ukhale wokwera mtengo, komanso umathandizira kukana kutsuka kwa utoto. Ma cellulose a Hydroxyethyl onse amathandizidwa ndi kuchedwa kwapang'onopang'ono, ndipo powonjezera ufa wowuma, amatha kuletsa caking ndikuonetsetsa kuti hydration imayamba pambuyo pakubalalika kokwanira kwa Hydroxyethyl Cellulose powder.
M'makampani opanga mankhwala atsiku ndi tsiku monga mankhwala otsukira mano, sopo, mafuta odzola ndi zodzoladzola, ndi mafuta odzola, Hydroxyethyl Cellulose imakhala ngati thickener, dispersing agent, binder and stabilizer kuonjezera kachulukidwe, lubrication, ndi mercerized maonekedwe a mankhwala.
- Hydroxyethyl cellulosea tsiku ndi tsiku mankhwala kalasi ali ndi ntchito zabwino mildew zosagwira, dongosolo thickening ndi rheology kusintha ntchito, komanso kusungirako madzi bwino ndi filimu mapangidwe, ndipo amapereka chomaliza zonse zowoneka ndi zonse zofunika ntchito ntchito. Hydroxyethyl Cellulose yopangidwa pamwamba imakhala ndi kusungunuka kwamadzi ozizira, ndipo ufa wowuma ukhoza kugwiritsidwa ntchito ndikuwonjezeredwa mwachindunji m'madzi. Good kubalalitsidwa kwa mankhwala m'madzi angapewe clumping wa mankhwala, ndi zimachitika m'njira kuvunda. Njira yomaliza yamadzimadzi ndi yunifolomu, mosalekeza komanso yodzaza.
- Hydroxyethyl celluloseangagwiritsidwe ntchito ngati thickener ndi simenti wothandizila workover madzimadzi zitsime mafuta. Zimathandiza kupereka yankho lomveka bwino ndi zinthu zochepa zokhazikika, motero kuchepetsa kwambiri kuwonongeka kwa mapangidwe a zitsime za mafuta. Madzi okhala ndi Hydroxyethyl Cellulose omwe amagwiritsidwa ntchito ngati thickening amawonongeka mosavuta ndi asidi, enzyme kapena oxidizing, ndipo amathandizira kwambiri kuchira kwa hydrocarbon. Pachitsime chamafuta, hydroxyethyl cellulose imagwiritsidwa ntchito ngati chonyamulira cha proppant. Madzi awa amatha kuwonongeka mosavuta ndi njira zomwe tafotokozazi.
Mphamvu ya hydroxyethyl cellulose
Hydroxyethyl cellulose ilibe phindu lililonse pakhungu koma imathandizira kuti mankhwalawa azigwira ntchito bwino. Chifukwa hydroxyethyl cellulose ndi stabiliser, amathandiza kusunga emulsions pamodzi. Izi zikutanthauza kuti mutha kugwiritsa ntchito maphikidwe anu odzola ndi batala kuti muwonjezere makulidwe ndi kukhazikika.
Amagwiritsidwanso ntchito ngati thickening wothandizira kuti apange mawonekedwe ofunikira komanso kusasinthika kwamafuta kapena mafuta odzola. Hydroxyethyl cellulose imapanganso filimu pakhungu, yomwe imalola kuti mankhwalawa apange mawonekedwe osalala komanso opitirira pakhungu. Izi zimapangitsa kuti khungu likhale lofewa komanso lofewa.
Hydroxyethyl cellulose viscosity
Hydroxyethyl cellulose ndi yopanda ionic, madzi osungunuka ufa, omwe amatha kusungunuka m'madzi ozizira komanso otentha. Kukhuthala kwa cellulose yathu ya hydroxyethyl ndi 30000-100000 cps.
Kodi HYDROXYETHYLCELLULOSE imachita chiyani pakupanga?
- Kumanga
- Kupanga mafilimu
- Kukhazikika
- Kuwongolera mamasukidwe
Chitetezo cha hydroxyethyl cellulose
Hydroxyethyl cellulose imawonedwa ngati chinthu chotetezeka chomwe chitha kugwiritsidwa ntchito muzopangira tsitsi ndi khungu. Nthawi zambiri amagwiritsidwa ntchito kukhazikika komanso kulimbitsa maphikidwe ndipo izi sizimayembekezereka kukwiyitsa khungu.
Kodi hydroxyethyl cellulose ndi yowopsa?
Pakali pano amagwiritsidwa ntchito m'magulu otsika kwambiri monga 0.0002%, ndipo mpaka 39%. Gulu lodziyimira pawokha la Cosmetic Ingredient Review lalamula kuti hydroxyethylcellulose ndi yotetezeka monga momwe amagwiritsidwira ntchito mu zodzoladzola, ngakhale pamlingo wokulirapo kuposa zomwe zingachitike chifukwa chodziwika bwino ndi anthu.
Kusamalitsa
Musanagwiritse ntchito Hydroxyethyl Cellulose, dziwitsani dokotala wanu za mndandanda wamankhwala omwe muli nawo panopa, mankhwala omwe ali pa kauntala (monga mavitamini, zowonjezera zitsamba, ndi zina zotero), ziwengo, matenda omwe analipo kale, ndi matenda omwe alipo panopa (monga mimba, opaleshoni yomwe ikubwera, ndi zina zotero. ). Matenda ena atha kukupangitsani kuti mukhale okhudzidwa kwambiri ndi zotsatira za mankhwalawa. Tengani monga mwalangizidwa ndi adokotala kapena tsatirani malangizo omwe asindikizidwa pachoyikapo. Mlingo umatengera momwe mulili. Uzani dokotala wanu ngati matenda anu akupitilira kapena akuipiraipira. Uphungu wofunikira walembedwa pansipa.
