Ishishini le-ether ye-cellulose phezulu

eyona mathiriyeli ekrwada efunekayo kwimveliso yei-cellulose etherzibandakanya umqhaphu osulungekileyo (okanye i-pulp yamaplanga) kunye nezinye izinyibilikisi zeekhemikhali eziqhelekileyo, ezifana nepropylene oxide, i-methyl chloride, i-liquid caustic soda, i-caustic soda, i-ethylene oxide, i-toluene kunye nezinye izinto ezincedisayo. Amashishini oshishino oluphezulu kolu shishino abandakanya umqhaphu osulungekileyo, amashishini okuvelisa iinkuni zomthi kunye namanye amashishini emichiza. Ukuguquguquka kwexabiso kwezinto eziphambili ezichazwe ngasentla ziya kuba neempembelelo ezahlukeneyo kwiindleko zemveliso kunye nexabiso lokuthengisa i-cellulose ether.

Iindleko zekotoni esulungekileyo ziphezulu. Ukuthatha i-ether yezinto zokwakha zebakala le-cellulose ether njengomzekelo, ngexesha lokunika ingxelo, iindleko zekotoni esulungekileyo zibalelwa kwi-31.74%, 28.50%, 26.59% kunye ne-26.90% yeendleko zentengiso yezinto zokwakha ibakala le-cellulose ether ngokulandelanayo. Ukuguquguquka kwexabiso lekotoni ecocekileyo kuya kuchaphazela iindleko zokuvelisa i-cellulose ether. Eyona nto iphambili kwimveliso yekotoni ecocekileyo yi-cotton linters. Iilitha zomqhaphu zezinye zeemveliso eziphuma kwinkqubo yokuvelisa umqhaphu, ikakhulu ezisetyenziselwa ukuvelisa i-cotton pulp, umqhaphu ococekileyo, i-nitrocellulose kunye nezinye iimveliso. Ixabiso lokusetyenziswa kunye nokusetyenziswa kwe-cotton linters kunye ne-cotton yahluke kakhulu, kwaye ixabiso layo lingaphantsi kunelomqhaphu, kodwa linokuhambelana okuthile kunye nokuguquguquka kwexabiso lomqhaphu. Ukuguquguquka kwexabiso le-cotton linters kuchaphazela ixabiso lekotoni ecocekileyo.

Ukuguquguquka okubukhali kwixabiso lekotoni ecocekileyo kuya kuba namaqondo ahlukeneyo empembelelo ekulawuleni iindleko zokuvelisa, ixabiso lemveliso kunye nenzuzo yamashishini kule shishini. Xa ixabiso lomqhaphu osulungekisiweyo liphezulu kwaye ixabiso le-pulp yeplanga lincinci, ukuze kuncitshiswe iindleko, i-pulp yomthi ingasetyenziselwa indawo kunye nokongeza umqhaphu osulungekisiweyo, ngakumbi ukuveliswa kwe-cellulose ethers kunye ne-viscosity ephantsi njenge ibakala lamayeza kunye nokutyai-cellulose ethers. Ngokwedatha evela kwiwebhusayithi ye-National Bureau of Statistics, ngo-2013, indawo yokutyala umqhaphu yelizwe lam yayiziihektare eziyi-4.35 yezigidi, kwaye imveliso yomqhaphu yelizwe yayiziitoni ezizigidi ezi-6.31. Ngokwezibalo ezivela kwi-China Cellulose Industry Association, kwi-2014, isiphumo esipheleleyo somqhaphu ococekileyo oveliswe ngabavelisi abakhulu basekhaya abacociweyo be-cotton yayiyi-332,000 yeetoni, kwaye ukunikezelwa kwezinto eziluhlaza kuninzi.

Izinto eziphambili zokwenziwa kwezixhobo zemichiza yegraphite yintsimbi kunye nekhabhoni yegraphite. Ixabiso lentsimbi kunye nekhabhoni yegraphite libalelwa kumlinganiselo ophezulu wexabiso lemveliso yezixhobo zemichiza yegraphite. Ukuguquguquka kwexabiso kwezi zixhobo zekrwada kuya kuba neempembelelo ezithile kwiindleko zemveliso kunye nexabiso lokuthengisa lezixhobo zemichiza yegraphite.
