Kodi hydroxyethyl ndi chiyani cellulose

Hydroxyethyl cellulose: chidule
Hydroxyethyl cellulose (hec) ndiopanda Polymer, solmer yosungunuka yochokera ku cellulose, polymer yochulukirapo padziko lapansi. Chifukwa cha zinthu zomwe zimasinthasintha, hec imagwiritsidwa ntchito kwambiri pamafakitale osiyanasiyana, kuphatikizapo zamankhwala osiyanasiyana, kuphatikiza mankhwala, zodzoladzola, utoto, ndi zomangamanga.

Synthesis ya hydroxyethyl cellulose
Kupanga kwa hec kumaphatikizapo kusinthika kwa cellulose. Njira iyi imayamba ndi cellulose kuthandizidwa ndi sodium hydroxide kupanga alkali cellulose. Ethylene oxide amawonjezeredwa ku kusakaniza uku, womwe umapangitsa hydroxethyl cellulose. Zomwe zikuchitikazo zitha kuyimiriridwa motere:

Cellulose-ch2ch2o → cellulose-och2ch2oh

Mlingo wa zolowa m'malo (DS) ndi molar zolowetsa (ms) ndi magawo ofunikira pakusankha katundu wa Hec. DS amatanthauza kuchuluka kwa magulu a hydroxyl pa molekyulu ya cellulose yomwe yasinthidwa, pomwe MS imawonetsa kuchuluka kwa maenje a ethylene a oxide pa Gawo la Glucose of Cellulose. Magawo awa amakopa kusandukira, mafakisoni, ndi zina za Hec.

Hec ali ndi zinthu zingapo zosiyanitsa:

Kusungunuka: Hec amasungunuka m'madzi otentha komanso ozizira, zomwe zimapangitsa kuti zikhale zosinthana ndi ntchito zosiyanasiyana. Itha kupanga zomveka, zothetsera zokwanira zomwe zimakhala zokhazikika pamawu ambiri.

Ma Isccess: Makutu a mayankho a HeC amatengera kunenepa komanso kudekha. Hec imatha kupanga maulendo osiyanasiyana, kupangitsa kuti ikhale yothandiza pamapulogalamu omwe amafunikira mawonekedwe apadera.

Kutha kwa makanema: Hec amatha kupanga mafilimu osinthika, owoneka bwino. Katunduyu ndi wothandiza kwambiri pakulankhula ndi zodzoladzola.

Wothandizira wamkulu: Hec ndi wothandizira wogwira ntchito mogwira mtima, amapereka kusachita bwino komanso kukhazikika pamapangidwe.

Kukhazikika: Hec ndi wokhazikika komanso wosagwirizana ndi kuwonongeka ndi kuwala, kutentha, ndi tizilombo tating'onoting'ono, komwe kumawonjezera moyo wake wokhathamira pamapulogalamu osiyanasiyana.

Mapulogalamu a hydroxyethyl cellulose
Chifukwa cha malo ake apadera, hec imapeza ntchito m'magawo angapo:

Mankhwala opanga mankhwala: M'makampani opanga mankhwala, Hec amagwiritsidwa ntchito ngati chofunda, makanema-omwe anali kale, komanso kukula kwa mapiritsi ndi mafuta. Zimathandizira pakuwongolera mankhwala osokoneza bongo ndipo imawongolera kapangidwe ndi kukhazikika kwa mapangidwe.

Zodzikongoletsera: Hec imagwiritsidwa ntchito pochita kusamalira ma shampoos, zodzola, ndi zowawa. Imapereka mawiri omwe adafunidwa, amathandizira kumva za malonda, ndikukhazikitsa emulsions.

Utoto ndi zokutira: M'mpani yopanga utoto, hic imachita ngati thiccener, okhazikika, ndi wogulitsa madzi. Zimakhala bwino kugwiritsa ntchito zojambula, zimalepheretsa kusaka, ndipo zimatsimikizira ngakhale mapangidwe a filimu.

Ntchito: Hec imagwiritsidwa ntchito pomanga ngati simenti ndi pulasitala. Zimathandizira kugwirira ntchito, kusungidwa kwamadzi, komanso kutsatira, kukonza magwiridwe antchito ndi kukhazikika kwa zinthuzi.

Makampani ogulitsa zakudya: Ngakhale kuti ndizofala, hec amatha kugwiritsidwa ntchito ngati thickir ndi okhazikika pazogulitsa zina, ndikuwonetsetsa kuti mawonekedwe osasinthika komanso osasinthika.

Makampani opanga malemba: Hec amagwiritsidwa ntchito ngati wogwirizira pamakampani opanga malembawo, amapereka mphamvu ndi kukhazikika ku ulusi pakuluka.

Chitetezo ndi chilengedwe
Hec nthawi zambiri amayesedwa kuti agwiritse ntchito ntchito zosiyanasiyana, makamaka mu mankhwala ndi zodzoladzola, komwe amayesedwa kwambiri kuti azitha kuvuta komanso kukwiya. Sikuti ndi poizoni, osakwiya, komanso hypoallergenic, ndikupanga kukhala koyenera kugwiritsa ntchito zinthu zomwe zimagwiritsidwa ntchito pakhungu kapena kusuta.

Kuchokera pamalingaliro azachilengedwe, Hec ndi biodegrable ndipo achokera ku zinthu zokonzanso (cellose). Kupanga ndi kugwiritsa ntchito kumagwirizanitsidwa ndi mphamvu yotsika. Komabe, monga ndi mankhwala onse, omwe amagwira bwino ntchito ndi otaya bwino kuti achepetse ngozi zilizonse zomwe zingachitike.

Hydroxyethyl cellulose ndi polymer komanso mtengo wofunikira ndi ntchito zingapo pamakampani osiyanasiyana. Malo ake apadera, monga kusungunuka madzi, kuwongolera mafakiti, kuthekera kwa makanema, komanso kukhazikika, zimapangitsa kuti zikhale zofunika kwambiri pazogulitsa kuchokera ku mankhwala onga zomanga. Kaphatikizidwe ka Hec kuchokera ku celluluse kumayimira kugwiritsa ntchito zachilengedwe moyenera, kumathandizira kukhalabe ndi moyo wake. Ndi mbiri ya chitetezo champhamvu komanso chilengedwe chochepa kwambiri, Hec ikupitiliza kukhala yofunika kwambiri mumitundu yosiyanasiyana yamalonda ndi mafakitale.
