ʻEnehana Old OLLUSE He'KOAS

Kaʻenehana oNā Naloʻopili i ka hoʻololiʻana o nā cellouse, kahi polymer kūlohelohe mai nā pā kaua, e hana i nā dericaties a me nā hana kūikawā. ʻO nā makemake o ka cellulose e pili ana i ka hydroxyprooparlloselflcelll milllcelll Eia kekahiʻike o kaʻenehana i hoʻohanaʻia ma ka hanaʻana o nā nahelē.

1. Kēia mea:
   • ʻO ka kumu kumu cellouse:ʻO ka mea nui o nā mea waiwai nui no ka mokuahi o ka cellulouse Hoʻopili ke kumu o ka celoulouse i nā waiwai o ka huahana cellouse hope loa.
2. Mākaukau o Cellulose:
   • Pulpped: E kauʻia nā lāʻau lāʻau a iʻole ka cotton i nā kaʻina hana e wāwahi i nā mea e wāwahi ai i keʻano o ka cellouse.
   • Hoʻomaʻemaʻe: hoʻomaʻemaʻeʻia ka cellulouse e wehe i nā mea haumia a me ka ligin, hopena i kahi mea i hoʻomaʻemaʻeʻia.
3. Modelid Modelication:
   • ʻO ka hopena ethefication:ʻO ke kumu nui i keʻano o ka cellouse eter comption ka hoʻololiʻana o ka ceditical o cellulose ma o nā meaʻala. Hoʻokomo kēia i ka hoʻopukaʻana i nā hui o Ether Group (eg, hydromexyl, hydroxytl
   • ʻO ke koho o nā hoʻoponopono: Nā reagents e like me Estlenene Oxide, Prostium
4. E kāohi i nā'āpana hoʻohālikelike:
   • ʻO ka mahana a me keʻano: nā hopena o ka eterification e hana pinepineʻia ma lalo o keʻano o keʻano o keʻano i makemakeʻia a e pale i nāʻano'āpana.
   • ʻO nā kūlana alkaline: He nui nā hopena otemalification i lalo o nā kūlana alkaline, aʻo ka ph o keʻano hoʻohālikelike.
5. Hoʻomaʻemaʻe:
   • Neutralization: Ma hope o ka hopena o ka ethesifification, ua hana pinepineʻia ka huahana e wehe i nā uku keu a iʻole nā ​​huahana.
   • ʻO ka holoiʻana: Ua holoiʻia ka cellulose i hoʻololiʻia e hoʻopau i nā mea kūlohelohe a me nā haumia.
6. Lohi:
   • Ua maloʻo ka hoʻomaʻemaʻeʻana o Wife Eter Eter Eter e loaʻa i ka huahana hope loa i ka pauna a iʻole keʻano granur.
7. Kākau pono:
   • ʻO ka loiloi: nā hana likeʻole e like me nā mea e like me nā mea i hoʻopaʻaʻia (NMR)
   • ʻO ke kiʻekiʻe o keʻano (DS): The DS
8. Ka hana a me ka noi:
   • ʻO nā mea hoʻohana i hoʻopauʻia: E hāʻawiʻia nā mea hoʻohana e nā mea hoʻohana e hoʻopau i nāʻoihana'ē aʻe, e komo pū me nā mea kanu, ka mālama pono, a me nā lole pilikino,
   • Nā helu noi-noi kiko'ī
9. Noiʻi a me ka hana hou:
   • Ke hoʻomau nei ka holomuaʻana: Ke noiʻi nei nā noiʻi a me nā hana noiʻi i ka hoʻomaikaʻiʻana i nā kaʻina hana, e hoʻonui ana i ka hana o nā noi collulouse.

He mea nui ia e hoʻomaopopo e pili ana i kaʻenehana no ka hanaʻana i nā mea e pili ana i nā mea i makemakeʻia e pili ana i nā waiwai a me nā noi. ʻO ka hoʻololiʻana o ka cellouse ma o nā mea e hoʻohuli ai i nā mea hana e hiki ai i kahi ākea o nā mea e pili ana i nā mea e pili ana i nāʻoihana.
