izinto eziphambili ezifunekayo ekuveliswenii-cellulose etherziquka umqhaphu ocociweyo (okanye i-pulp yomthi) kunye nezinye izinyibilikisi zeekhemikhali eziqhelekileyo, ezifana ne-propylene oxide, i-methyl chloride, i-caustic soda engamanzi, i-caustic soda, i-ethylene oxide, i-toluene kunye nezinye izinto ezincedisayo. Amashishini akwishishini eliphambili kweli shishini aquka umqhaphu ocociweyo, amashishini okuvelisa i-pulp yomthi kunye namanye amashishini eekhemikhali. Ukuguquguquka kwamaxabiso kwezinto eziphambili ezikhankanyiweyo apha ngasentla kuya kuba nefuthe elahlukileyo kwiindleko zemveliso kunye nexabiso lokuthengisa le-cellulose ether.
Ixabiso lomqhaphu ocociweyo liphezulu kakhulu. Xa sijonga i-cellulose ether yezixhobo zokwakha njengomzekelo, ngexesha lengxelo, ixabiso lomqhaphu ocociweyo libalelwa kwi-31.74%, 28.50%, 26.59% kunye ne-26.90% yeendleko zokuthengisa ze-cellulose ether yezixhobo zokwakha ngokwahlukeneyo. Ukuguquguquka kwamaxabiso komqhaphu ocociweyo kuya kuchaphazela iindleko zokuvelisa i-cellulose ether. Izinto ezisetyenziswa kakhulu ekuveliseni umqhaphu ocociweyo zii-cotton linters. Ii-cotton linters zezinye zeemveliso eziphuma kwinkqubo yokuvelisa umqhaphu, ezisetyenziselwa kakhulu ukuvelisa i-cotton pulp, umqhaphu ocociweyo, i-nitrocellulose kunye nezinye iimveliso. Ixabiso lokusetyenziswa kunye nokusetyenziswa kwee-cotton linters kunye nomqhaphu zahlukile kakhulu, kwaye ixabiso lazo liphantsi ngokucacileyo kunelo lomqhaphu, kodwa linolwalamano oluthile nokuguquguquka kwamaxabiso komqhaphu. Ukuguquguquka kwamaxabiso e-cotton linters kuchaphazela ixabiso lomqhaphu ocociweyo.
Ukuguquguquka okukhulu kwexabiso lomqhaphu ocociweyo kuya kuba nefuthe elahlukileyo kulawulo lweendleko zemveliso, amaxabiso emveliso kunye nenzuzo yamashishini kweli shishini. Xa ixabiso lomqhaphu ocociweyo liphezulu kwaye ixabiso lomqhaphu womthi liphantsi kakhulu, ukuze kuncitshiswe iindleko, umqhaphu womthi ungasetyenziswa endaweni yawo kwaye ungezelele umqhaphu ocociweyo, ikakhulu ekuveliseni ii-ethers ze-cellulose ezine-viscosity ephantsi njengeyeza kunye nomgangatho wokutya.ii-ether ze-celluloseNgokwedatha evela kwiwebhusayithi ye-National Bureau of Statistics, ngo-2013, indawo yokutyala umqhaphu kwilizwe lam yayiyi-4.35 yezigidi zeehektare, kwaye imveliso yomqhaphu kazwelonke yayiyi-6.31 yezigidi zeetoni. Ngokwezibalo ezivela kwi-China Cellulose Industry Association, ngo-2014, imveliso iyonke yomqhaphu ocociweyo owenziwe ngabavelisi abakhulu bemqhaphu ocociweyo basekhaya yayiyi-332,000 yeetoni, kwaye ukunikezelwa kwezinto eziluhlaza kuninzi.
Izinto eziphambili zokwenza imveliso yezixhobo zeekhemikhali zegrafiti yintsimbi kunye negrafiti carbon. Ixabiso lentsimbi kunye negrafiti carbon libandakanya inxenye ephezulu yeendleko zemveliso yezixhobo zeekhemikhali zegrafiti. Ukuguquguquka kwamaxabiso kwezi zinto kuya kuba nefuthe elithile kwixabiso lemveliso kunye nexabiso lokuthengisa izixhobo zeekhemikhali zegrafiti.
