EipponCell® HEMC LH 6000 Cellulose ether waa wax lagu daro isku dhafan oo loo isticmaalo hoobiye dahaarka kulaylka.Ku darida maadada hoobiyeyaasha ayaa saameyn muuqata ku leh qallajinta walxaha.Waxa xiiso leh, marka maaddada hydroxyethyl methylcellulose sii korodho, qallajinta qalajinta ayaa marka hore hoos u dhacda ka dibna korodho.Qiimaha ugu hooseeya iyo kan ugu sarreeya ayaa lagu arkay 2.4% iyo 3% ka kooban, siday u kala horreeyaan.
Sidoo kale, hoobiye dahaarka kulaylka inorganic sidoo kale waxay soo bandhigaysaa isbeddel la mid ah khasaaraha tirada badan iyo engejinta ee lagu daro ether cellulose.Khasaare ballaaran ayaa marka hore hoos u dhacaya, isagoo gaaraya ugu yaraan 3% maadada, laakiin ka dibna wuxuu kordhiyaa kororka etherka cellulose.Waxaa xusid mudan, luminta tirada badan iyo yaraynta qalajinta si toos ah uma xidhna.
Ku darida hydroxyethyl methylcellulose waxay si togan u saamaysaa xajmiga daloolka ee hoobiye dahaarka kulaylka.Meelo badan oo kala duwan ayaa ka muuqda cabbirrada daloolka ka hooseeya 5nm iyo 10nm, taasoo horseedaysa isbeddel hoos u dhaca marka hore ka dibna sii kordhaya cabbirrada daloolka ka hooseeya 10nm maaddaama nuxurka etherka cellulose uu kordhayo.Marka qiyaasta ether-ka cellulose ay gaarto 3%, dhexroorka dalool ee ka yar 10nm ayaa ka sarreeya hoobiyeyaal kale oo kulaylka aan noolaha ahayn.
Intaa waxaa dheer, waxa ku jira ether-ka cellulose-ku wuxuu saameeyaa cabbirka daloolka ugu macquulsan, kaas oo soo bandhigaya qaabka sii kordhaya ka dibna hoos u dhacaya.Cabbirrada daloolada yaryar, ee ay u badan tahay waxay u dhigmaan qiyamka yaraynta qalajinta, halka cabbirrada daldaloolada ee ugu badan ee suurtogalka ah ay la xiriiraan qiyamka yaraynta qalajinta.
