The main raw materials of cellulose ether are agricultural and forestry products such as refined cotton and wood pulp, and chemical products such as propylene oxide, methyl chloride and caustic soda. Izinto ezingafunekiyo zekotoni ecocekileyo zii-cotton ezine. Ilizwe lam lityebile kwikotoni, ngakumbi eShandong, iXinjaiang, Hebei, Jiangsu kunye nezinye iindawo eziphambili zekotoni. Izixhobo ze-cotton ze-cotton zityebile kakhulu kwaye ubonelelo lwanele; Iimveliso zekhemikhali ezifana ne-propylene oxide kunye ne-methyl chloride zezeshishini lepetrochemical. Iimveliso eziqhelekileyo zekhemikhali ezisetyenzisiweyo, amashishini okuvelisa onke aphelela eShandong, uHannan, uZhejiang nakwezinye iindawo, kwaye unikezo lwanele.
Umqhaphu sisityalo kunye nemveliso yezolimo ye-bulk. Ngenxa yempembelelo yeemeko zendalo kunye nokunikezelwa kwamanye amazwe kunye nemfuno, ixabiso liqhele ukuguquguquka. Amaxabiso eemveliso zekhemikhali ezifana ne-propylene oxide kunye ne-methyl chloride nazo ziphantsi kokutshintsha kwamaxabiso e-oyile yamanye amazwe. Ukusukela kwi-akhawunti engaphantsi kwe-Akhawunti ye-Special ye-Telulose Ether, ukuguquguquka kwixabiso lezinto ezibukhali kuya kuba nefuthe ngqo kwixabiso lentengiso leseti yeselselese.
Ukuguquguquka kwamaxabiso ezinto ezinqabileyo ezinezixhobo ezilandelayo kuphuhliso lweShishini le-Ether Ither: dlulisa kwisiphumo. Ngokubanzi, amashishini anemveliso ephezulu ye-Tech, iipotifoliyo ezityebileyo, kunye neemveliso eziphezulu zexabiso elongeziweyo zinezakhono zokudluliselwa kwexabiso, kwaye iinkampani ziya kugcina inqanaba elizinzileyo lengeniso; Iinkampani ezinemveliso ye-Tech ephantsi, iipotifoliyo zemveliso enye, kunye neemveliso eziphantsi zexabiso eziphantsi zinobuchule obuthathaka bokudlulisela, uxinzelelo lweendleko zamashishini luphezulu. .
