He aha ke kaʻina hana o ka hanaʻana o ka mitylcellse?

ʻO ka mathylcellse ʻO kāna kaʻina hana e pili ana i nāʻano hana he nui,ʻo ka nui e komo pū me nāʻano koho balota, hoʻololiʻia, e maloʻo a maloʻo.

1.ʻO ka loaʻaʻana o ka cellulose
ʻO nā mea waiwai nui o ka huiʻana o ka mitylcreellse maoli ka collulose maoli,ʻo ia ka mea maʻamau i loaʻa mai ka lāʻau lāʻau a iʻole cotton. ʻO ka mea mua, ua kauʻia ka lāʻau a iʻole ka lāʻau a iʻole ka cotton i kahi papa hana e wehe ai i nā haumia (e like me ka linin, etc.) ʻO nā ala hana maʻamau e komo ai i keʻano o ACID-Sense a me keʻano enzyMatic. Ma keʻano hana ACID-Sense, Wood a iʻole COTTO PLUE PRODE me SODUTIMY HYDROXIDE (Naoheal a me nā mea'ē aʻe.

2, ka hopena o ka eterification o ka cellulose
Ma hope aʻe, kahi hopena othlylation (ethetification reaction ʻO ka hana koho o ka hana o ka hoʻohuliʻana e hana hou ai i ka cellouse me kahi mea hana mitylating (ka maʻamau mathyl ʻO ka hana kiko'ī penei:

ʻO ke kohoʻana o ka reaction Solivent: Polar Couvents
Nā Kūlana Kūlana: Ua laweʻia ka hopena ma kahi mahana a me ke kaomi, aʻo keʻano maʻamau maʻamau he 50-70 ° C. I ka hopena o ka hopena, hui pūʻiaʻo Mithsk chrlode me ka hui hydroxyl (-oh) i ka mollulune e hoʻohuli ai i ke kelepona.
Ka mana o ka mana ʻO ka manawa lōʻihi a lōʻihi paha ka hopena kiʻekiʻe a iʻole ka nui o keʻano o ka cellulose,ʻoiai he haʻahaʻa haʻahaʻa a iʻole keʻano o ka hanaʻana o keʻano o ka cellulose.

Ma hope o ka hoʻopauʻana o ka hopena,ʻaʻole i noho mau nā mea hana uila a me nā catalysts a me nā catalysts i loko o ka huahana cellulose, pono e hoʻomaʻemaʻeʻia a hoʻomaʻemaʻe. Hoʻohana pinepineʻia ke kaʻina hana maʻamau i kahi hopena Acidic (e like me ka hopena Actitic acitic) e hana hou i nā mea alkaline i nā huahana. Hoʻohana ka hana hoʻomaʻemaʻe hoʻomaʻemaʻe i kahi nui o ka wai a iʻole ka waiʻona e wehe i nā mea i hanaʻoleʻia a me nā huahana ma hope o keʻano o ka huahana hope.

4. E hoʻomaloʻo a me ka crushing
Ma hope o ka holoiʻana,ʻo ka mathylcelllose maʻamau ma kahi pākaukau a iʻole gel state state, no laila e pono e maloʻo i kahi huahana pwded. Nui nā ala e maloʻo ai, a me nā mea maʻamau maʻamau e komo ai i ka maloʻoʻana, hoʻokaʻawale i ka maloʻo a me ka maloʻo maloʻo. I ka wā o ke kaʻina hana maloʻo, pono ke mahana a me ka haʻahaʻa e mālama ponoʻia e pale i ka decomposition e paleʻia e ka nui o nā gel.

Ma hope o ka maloʻo, pono e loaʻa ka mana o ka mitylcelloulose e hoʻokō i ka nui o ka'āpana i koiʻia. Ua hoʻopauʻia ka hanaʻokiʻana e ka lewa mokulele a iʻole ka mīkini uila. Ma ka paleʻana i ka nui o ka'āpana o ka'āpana

Ma hope o ka hakakāʻana, pono ka methylcelllolose e hoʻopili i ka mana kūpono kūpono e hōʻoia ai e hālāwai me nā kiko'īʻenehana. Nā Kūlana Kūlana maʻamau:

ʻO kaʻikeʻana o ka Moistoure
ʻO ka hoʻokaʻawaleʻana o ka'āpana:ʻO ka nui a me ka nui a me ka hoʻoiliʻana o nā'āpana e pili ana i ka sotular o ka huiʻana o ka huiʻana.
ʻO ke kiʻekiʻe o ka mityylation:ʻO ke kiʻekiʻe o ka mityylation he hōʻailona nui no ka loiloiʻana i ka maikaʻi o ka mitylcellse, e pili ana i kona hopena a me ka hana noi.
SOLUBITITE MA VISCOSIty:ʻO ka pālolo a me keʻano o keʻano o ka mathylcelllose he nui nā papa hana nui i kāna noi,ʻoi aku ka lāʻau lapaʻau.
Ma hope o ka heleʻana i ka nānāʻana, e hoʻopaʻaʻia ka huahana e like me nā pono likeʻole, maʻamau i nāʻeke pepa a me nā helu helu a me nāʻike'ē aʻe.

6.ʻO ka palekana palekana a me ka palekana
I ka wā hana o ka hana hoʻolālā o MilletLose, pono e koiʻia nā ana palekana palekana no ka maʻi lapaʻau no ka maʻi a me nā mea hoʻoponopono i hoʻohanaʻia i ke kaʻina hana. Ma hope o ka hopena, pono e mālamaʻia ka waiʻole a me ka waiʻole e pale aku ai i ka paleʻana i kaʻona. Eia kekahi,ʻo nā hana kaulike e pono ai ke hana i ke kaʻina hana e pono ai e like me nā kaʻina hana palekana e hōʻoia ai i ka palekana o nā limahana.

ʻO ke kaʻina hana hana o ka mana o Mityl e pili ana i ka nui o ka celilouse, ka hopena o ka hanaʻana, ka holoiʻana a me ka neʻeʻana. He hopena nui kēlā me kēia loulou i ka maikaʻi o ka huahana hope loa, no laila e kāohi a nānā i ke kaʻina hana hana koʻikoʻi. Ma o kēia mau kaʻina hana,ʻo Melyl Cellulouse e hālāwai me nā koi noi likeʻole e hiki ke hanaʻia.
