M'makampani omanga ndi opaka utoto masiku ano, ziyembekezo za magwiridwe antchito ndizapamwamba kuposa kale lonse. Omanga, makontrakitala, ndi opanga amafuna zipangizo zomwe zimaperekakulimba, kugwira ntchito bwino, kugwiritsa ntchito mosavuta, komanso kugwirizana ndi chilengedwePakati pa kusinthaku pali gulu la zipangizo zamakono zodziwika kutiethers a cellulosendiMethyl Hydroxyethyl Cellulose (MHEC) akutuluka ngati chimodzi mwa zofunika kwambiri.
MHEC imagwiritsidwa ntchito kwambiri mumatope osakaniza ndi madzindimakina opaka utoto ochokera m'madzi, komwe imagwira ntchito ngati chowonjezera cha ntchito zambiri. Kuthekera kwake kokonza kusunga madzi, kuwongolera rheology, kuwonjezera kumamatira, ndi kukhazikika kwa mapangidwe kumapangitsa kuti ikhale yofunika kwambiri mu kapangidwe kamakono ka mankhwala.
Atsogoleri apadziko lonse lapansi monga Dow Chemical Company, Ashland Global Holdings Inc., ndi Shin-Etsu Chemical Co., Ltd. akupitilizabe kupanga ndi kugwiritsa ntchito MHEC, zomwe zikuwonetsa kufunika kwake komwe kukukula m'misika yapadziko lonse lapansi.
1. Kodi MHEC ndi chiyani? Kapangidwe ndi Zofunikira za Mankhwala
Methyl Hydroxyethyl Cellulose (MHEC) ndi mankhwala ophera tizilombo toyambitsa matenda.ether ya cellulose yosakhala ya ioniczochokera ku cellulose yachilengedwe, yomwe nthawi zambiri imachokera ku zinthu zopangidwa ndi matabwa kapena thonje. Kudzera mu kusintha kwa mankhwala, magulu a hydroxyl mu cellulose amalowetsedwa m'malo ndimethyl (-CH₃)ndihydroxyethyl (-CH₂CH₂OH)magulu.
Zinthu Zazikulu Zamankhwala
- Chilengedwe chosakhala cha ionic → chikugwirizana bwino kwambiri
- Kusungunuka kwa madzi ambiri
- Magiredi osinthika a kukhuthala
- Kukhazikika kwa kutentha
- Luso lopanga mafilimu
Zosinthazi zimasintha cellulose yaiwisi kukhala polima yogwira ntchito bwino kwambiri yoyenera kugwiritsidwa ntchito m'mafakitale ovuta.
