Mtengo wa HEMC LH6000

EipponCell® HEMC LH 6000 hydroxyethyl methyl cellulose ndi cellulose yopanda ionic yosakanikirana ndi etere yopangidwa kudzera mu ndondomeko ya mankhwala yomwe imaphatikizapo thonje, nkhuni alkalized, ethylene oxide, ndi methyl chloride ether.Pakalipano, njira yopangira HEMC ikhoza kugawidwa m'njira ziwiri zazikulu: njira yamadzimadzi ndi njira ya gasi.Mu njira yamadzimadzi, zida zomwe zimagwiritsidwa ntchito zimakhala ndi zofunikira zochepa zamkati, zomwe zimapangitsa kuti zikhale zowopsa.Ma cellulose amawaviikidwa mu lye, zomwe zimapangitsa kutupa kwathunthu ndi alkalization.Kutupa kwa osmotic kwamadzimadzi kumapindulitsa cellulose, zomwe zimapangitsa kuti zinthu za HEMC zikhale ndi digiri yofananira m'malo ndi kukhuthala.Komanso, njira yamadzimadzi gawo amalola mosavuta mankhwala zosiyanasiyana m'malo.Komabe, mphamvu yopangira riyakitala imakhala yochepa (nthawi zambiri pansi pa 15m3), zomwe zimapangitsa kuti pakhale kofunikira kuwonjezera kuchuluka kwa ma reactor kuti apange apamwamba.Kuonjezera apo, kachitidwe kameneka kamafuna kuchuluka kwa zosungunulira za organic monga chonyamulira, zomwe zimapangitsa kuti nthawi yayitali (nthawi zambiri imadutsa maola 10), kuwonjezeka kwa zosungunulira distillation, ndi nthawi yokwera mtengo.Kumbali inayi, njira ya gasi-gawo imaphatikizapo zida zogwirira ntchito ndipo imapereka zokolola zambiri zamagulu amodzi.Zomwe zimachitika mu autoclave yopingasa, yokhala ndi nthawi yocheperako (nthawi zambiri maola 5-8) poyerekeza ndi njira yamadzimadzi.Njira imeneyi sikutanthauza zovuta zosungunulira kuchira dongosolo.Zochitazo zikamalizidwa, methyl chloride yochulukirapo ndi dimethyl ether imasinthidwanso ndikugwiritsiridwa ntchito mosiyana kudzera munjira yochira.Njira ya gasi imakhala yotsika mtengo komanso kuchepa kwa ntchito, zomwe zimapangitsa kuti mtengo wake ukhale wotsika poyerekeza ndi njira yamadzimadzi.Komabe, njira ya gawo la gasi imafuna ndalama zambiri pazida ndi kuwongolera zokha, zomwe zimapangitsa kuti pakhale luso lapamwamba komanso ndalama zofananira. Komwe mungagule Cas HEMC LH 6000
