Pehea e hana ai i nā celoulouse?

ʻO ka hanaʻana o nā nalima cellouse e pili ana i ka hoʻololiʻana i ka collically collify ʻO nāʻano maʻamau maʻamau o nā mea e pili ana i ka cellouse e komo i ka cellulouse (mc), hydroxythol milllulse (hpmc), a me nā mea'ē aʻe. ʻO keʻano kūpono e pili ana i keʻano e pili ana i ka cellouse kiko'ī i hanaʻia, akā like nā hana laulā. Eia kekahi o kaʻike hou:

Nā Kūlana Nui no ka hanaʻana i nā'āpana cellose:

1.

• ʻO ka mea hoʻomaka e pili ana i ka collulose kūlohelohe, loaʻa pinepine mai ka lāʻau lāʻau a iʻole ka cotton. ʻO ka cellulouse maʻamau ma keʻano o ka pulu o ka pulu celified.

2. Alkalization:

• Hanaʻia ka cellouse me kahi hopena alkaline, e like me ka sodium hydroxide (Naoh), e hoʻoulu i nā hui hydroxyl ma ke kaulahao hydrosel ma ke kaula. ʻO kēia hana alkalization he mea nui no ka derivatization hou aʻe.

3, ka hooweliweli:

• ʻO ka celilose e hoʻopauʻia e ka eterification, kahi i hōʻikeʻia ai nā pūʻulu eter ether likeʻole i ka hope o ke kua. ʻO keʻano kiko'ī o Eter Group i hōʻikeʻia (Mathyl, HydroxyEthyl, hydroyproopsl, ka carboxytomy.
• ʻO ke kaʻina hana e pili ana i ka hopena o ka cellouse me nā hoʻoponopono kūpono, e like me:
  • No Materyl Cellulouse (MC)
  • No ka hydromexthyl celluse (hec)
  • No ka hydroxyproproplosel mathysl cellulse (hpmc):ʻO ka mālama me ka problelene oxide.
  • No ka carboxyemyll cellulouse (cmc): ka hana me ka sdium chlorocatete.

4.

• Ma hope o ka hoʻopioʻana,ʻo keʻano o ka celious resumoulse derivative maʻamau e wehe i kahi alkili A laila holoiʻia ka huahana e hoʻopau i nā haumia a me nā huahana.

5. E hoʻomaʻemaʻe a me ka milling:

• Hoʻoliloʻia ka cellouse eter e wehe i ka wai nui a laila i hoʻopiliʻia i loko o kahi pauka maikaʻi. Hiki ke mālamaʻia ka nui o ka'āpana ma luna o ka noi i manaʻoʻia.

6.

• ʻO ka papa inoaʻo Will Cellulose eter i nā hōʻike hoʻokele maikaʻi e hōʻoia ai e pili ana i kaʻikeʻana, me nā mea kiko'ī, nā wahi'ē aʻe, a me nā waiwai'ē aʻe.

He mea nui ia e hoʻomaopopo i ka hanaʻana o ka hana o nā nahesa e hoʻohanaʻia e nā mea hana kūikawā e hoʻohana ana i nā kaʻina hana. Nā kūlana kūikawā, hoʻoponopono hou, a me nā mea hana i hoʻohanaʻia e hiki ke hoʻololiʻia e pili ana i nā waiwai i makemakeʻia a me ka noi i manaʻoʻia. Hoʻohuiʻia, he mea pono nā hana palekana i ka wā o nā kaʻina hoʻololi hoʻololi.
