ʻo ia nā mea maka nui e pono ai no ka hana ʻana ocellulose eterae komo pū me ka pulupulu hoʻomaʻemaʻe (a i ʻole ka pulp lāʻau) a me kekahi mau mea hoʻoheheʻe kemika maʻamau, e like me propylene oxide, methyl chloride, wai ʻāpala wai, ʻāpala wai, ethylene oxide, toluene a me nā mea kōkua ʻē aʻe. ʻO nā ʻoihana ʻoihana o luna o kēia ʻoihana e pili ana i ka pulupulu hoʻomaʻemaʻe, nā ʻoihana hana pulp lāʻau a me kekahi mau ʻoihana kemika. ʻO ke kumukūʻai kūʻai o nā kumu waiwai nui i ʻōlelo ʻia ma luna nei e loaʻa i nā pae like ʻole o ka hopena i ke kumukūʻai hana a me ke kumukūʻai kūʻai aku o cellulose ether.
He kiʻekiʻe ke kumukūʻai o ka pulupulu hoʻomaʻemaʻe. ʻO ka lawe ʻana i nā mea hale hale cellulose ether ma ke ʻano he laʻana, i ka wā hōʻike, ʻo ke kumukūʻai o ka pulupulu hoʻomaʻemaʻe i helu ʻia no 31.74%, 28.50%, 26.59% a me 26.90% o ke kumukūʻai kūʻai o ka hale hale papa cellulose ether. ʻO ke kumukūʻai o ka pulupulu i hoʻomaʻemaʻe ʻia e pili i ke kumu kūʻai o ka cellulose ether. ʻO ka mea maka nui no ka hana ʻana i ka pulupulu i hoʻomaʻemaʻe ʻia ʻo ia nā liters pulupulu. ʻO ka pulupulu linter kekahi o nā huahana i loko o ke kaʻina hana pulupulu, hoʻohana nui ʻia e hana i ka pulupulu pulupulu, ka pulupulu hoʻomaʻemaʻe, nitrocellulose a me nā huahana ʻē aʻe. ʻOkoʻa loa ka waiwai hoʻohana a me ka hoʻohana ʻana i ka pulupulu a me ka pulupulu, a ʻo kona kumukūʻai ʻoi aku ka haʻahaʻa ma mua o ka pulupulu, akā aia kekahi pilina me ke kumukūʻai o ka pulupulu. Hoʻopili ke kumukūʻai o ka pulupulu linter i ke kumukūʻai o ka pulupulu hoʻomaʻemaʻe.
E loaʻa nā ʻano like ʻole o ka hoʻololi ʻana i ke kumukūʻai o ka pulupulu i hoʻomaʻemaʻe ʻia i ka mālama ʻana i nā kumukūʻai hana, nā kumukūʻai huahana a me ka loaʻa kālā o nā ʻoihana i kēia ʻoihana. Ke kiʻekiʻe ke kumukūʻai o ka pulupulu i hoʻomaʻemaʻe ʻia a ʻoi aku ka liʻiliʻi 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 hoʻohui no ka pulupulu hoʻomaʻemaʻe ʻia, ka mea nui no ka hana ʻana i nā cellulose ethers me ka viscosity haʻahaʻa e like me lāʻau lapaʻau a me ka papa meaʻaicellulose ethers. Wahi a ka ʻikepili mai ka pūnaewele o ka National Bureau of Statistics, i ka makahiki 2013, ʻo 4.35 miliona mau ʻeka ka wahi kanu pulupulu o koʻu ʻāina, a he 6.31 miliona mau tons ka hua pulupulu aupuni. Wahi a nā helu helu mai ka China Cellulose Industry Association, i ka makahiki 2014, ʻo ka huina o ka pulupulu hoʻomaʻemaʻe i hana ʻia e nā mea hana pulupulu hoʻomaʻemaʻe nui i loko o ka home he 332,000 tons, a ua nui ka lako o nā mea maka.
ʻO nā mea waiwai nui no ka hana ʻana i nā mea kemika graphite he kila a me ka kalapona graphite. ʻO ke kumu kūʻai o ke kila a me ka graphite carbon moʻokāki no kahi kiʻekiʻe kiʻekiʻe o ke kumukūʻai hana o nā mea hana kemika graphite. ʻO ke kumukūʻai o kēia mau mea maka e loaʻa kekahi hopena i ke kumukūʻai hana a me ke kumukūʻai kūʻai aku o nā mea kemika graphite.
