ʻOihana Cellulose ether ma uka

nā mea nui e pono ai no ka hana ʻana oʻEtera cellulosee komo pū me ka pulupulu i hoʻomaʻemaʻe ʻia (a i ʻole ka pulp lāʻau) a me kekahi mau mea hoʻoheheʻe kemika maʻamau, e like me ka propylene oxide, methyl chloride, soda caustic wai, soda caustic, ethylene oxide, toluene a me nā mea kōkua ʻē aʻe. ʻO nā ʻoihana ʻoihana luna o kēia ʻoihana e komo pū me ka pulupulu i hoʻomaʻemaʻe ʻia, nā ʻoihana hana pulp lāʻau a me kekahi mau ʻoihana kemika. ʻO nā loli kumukūʻai o nā mea maka nui i ʻōlelo ʻia ma luna nei e loaʻa nā ʻano like ʻole o ka hopena i ke kumukūʻai hana a me ke kumukūʻai kūʻai aku o ka cellulose ether.

He kiʻekiʻe ke kumukūʻai o ka pulupulu i hoʻomaʻemaʻe ʻia. Ma ka lawe ʻana i ka cellulose ether papa mea hale ma ke ʻano he laʻana, i ka wā hōʻike, ʻo ke kumukūʻai o ka pulupulu i hoʻomaʻemaʻe ʻia he 31.74%, 28.50%, 26.59% a me 26.90% o ke kumukūʻai kūʻai aku o ka cellulose ether papa mea hale. ʻO ka loli o ke kumukūʻai o ka pulupulu i hoʻomaʻemaʻe ʻia e hoʻopilikia i ke kumukūʻai hana o ka cellulose ether. ʻO ka mea maka nui no ka hana ʻana o ka pulupulu i hoʻomaʻemaʻe ʻia he pulupulu linter. ʻO nā pulupulu linter kekahi o nā huahana ʻaoʻao i ke kaʻina hana hana pulupulu, i hoʻohana nui ʻia e hana i ka pulp pulupulu, ka pulupulu i hoʻomaʻemaʻe ʻia, ka nitrocellulose a me nā huahana ʻē aʻe. He ʻokoʻa loa ka waiwai hoʻohana a me ka hoʻohana ʻana o nā pulupulu linter a me ka pulupulu, a ʻoi aku ka haʻahaʻa o kona kumukūʻai ma mua o ka pulupulu, akā he pilina koʻikoʻi kona me ka loli o ke kumukūʻai o ka pulupulu. Hoʻopilikia ka loli o ke kumukūʻai o nā pulupulu linter i ke kumukūʻai o ka pulupulu i hoʻomaʻemaʻe ʻia.

ʻO nā loli koʻikoʻi o ke kumukūʻai o ka pulupulu i hoʻomaʻemaʻe ʻia e loaʻa nā ʻano hopena like ʻole i ka kaohi ʻana i nā kumukūʻai hana, ke kumukūʻai huahana a me ka loaʻa kālā o nā ʻoihana ma kēia ʻoihana. Ke kiʻekiʻe ke kumukūʻai o ka pulupulu i hoʻomaʻemaʻe ʻia a ʻoi aku ka haʻahaʻa o ke kumukūʻai o ka pulp lāʻau, i mea e hōʻemi ai i nā kumukūʻai, hiki ke hoʻohana ʻia ka pulp lāʻau ma ke ʻano he pani a me ka hoʻohui no ka pulupulu i hoʻomaʻemaʻe ʻia, ʻo ia hoʻi no ka hana ʻana i nā ethers cellulose me ka viscosity haʻahaʻa e like me ka lāʻau lapaʻau a me ka papa meaʻai.nā ethers celluloseWahi a ka ʻikepili mai ka pūnaewele o ka National Bureau of Statistics, i ka makahiki 2013, ʻo ka nui o ka wahi kanu pulupulu o koʻu ʻāina he 4.35 miliona heketa, a ʻo ka nui o ka pulupulu aupuni he 6.31 miliona tone. Wahi a nā helu helu mai ka China Cellulose Industry Association, i ka makahiki 2014, ʻo ka nui o ka pulupulu i hoʻomaʻemaʻe ʻia i hana ʻia e nā mea hana pulupulu kūloko nui he 332,000 tone, a nui ka lako o nā mea maka.

ʻO ke kila a me ke kalapona graphite nā mea maka nui no ka hana ʻana i nā lako kemika graphite. ʻO ke kumukūʻai o ke kila a me ke kalapona graphite kekahi hapa nui o ke kumukūʻai hana o nā lako kemika graphite. ʻO nā loli kumukūʻai o kēia mau mea maka e loaʻa kahi hopena i ke kumukūʻai hana a me ke kumukūʻai kūʻai aku o nā lako kemika graphite.
