Kugwiritsiridwa ntchito kwa EipoonCell® HEMC LH 4000 pazida zodzipangira zokha pansi ndipo kumapereka chidziwitso pamikhalidwe yapadera ya HEMC.HEMC ndi ether yamagulu ambiri osakanikirana ndi methoxy ndi hydroxyethoxy, ndi mwayi waukulu wopanda gel osakaniza ndi kusintha kwa kutentha, mosiyana ndi ma cellulose ethers monga HPC ndi MC.Ngakhale HEMC ili ndi mfundo ya gel, imapezeka pa kutentha kwakukulu, ndipo kuonjezera zomwe zili mu hydroxyethoxy zimasuntha gel point mpaka kutentha kwambiri.Katunduyu amapangitsa kuti ikhale yopindulitsa muzosakaniza zamatope, chifukwa zimathandizira kuchedwetsa phala la simenti pakutentha kwambiri.Kuphatikiza apo, HEMC ikuwonetsa magwiridwe antchito apamwamba m'mafakitale osiyanasiyana, kuphatikiza chakudya, utoto, ndi zovala zamankhwala.
Kupanga kwamakono kwa HEMC m'misika yapakhomo kumakumana ndi zovuta chifukwa cha kupanga kwazing'ono, zomwe zimayambitsa kusinthasintha kwa khalidwe lazogulitsa komanso kusowa kovomerezeka.Komabe, kuthekera kokwaniritsa njira yokonzekera HEMC ndikukwaniritsa kupanga kochulukira kumakhala ndi lonjezo lalikulu pakuwongolera kusasinthika ndi mtundu wa mankhwalawo.Kukhathamiritsa kumeneku kumatha kuchititsa kuti anthu ambiri azilandira m'mafakitale osiyanasiyana, kupindula ndi zinthu zapadera komanso zabwino za HEMC.
