ʻO keʻano o keʻano o ka cellouse eter derivatives

ʻO nā mea e loaʻa ai nā keiki elima o ka cellulose, kahi polysacarchide kūlohelohe i loaʻa i loko o nā paia o nā mea kanu. ʻO keʻano o keʻano o ke aniani e hōʻikeʻia e ka hoʻomakaʻana o nā pūʻulu o nāʻano o nā mea kanu o keʻano o keʻano o ka comentroxyl (-oh) ʻO nāʻano maʻamau maʻamau o nā leka uila e komo ai:

1. Hydroxyprooppropsllse (HPMC):
   • Kūlana:
     • ʻO HPMC ka synthestized ma ka hoʻopiliʻana i nā hui hydroxyl o nā cellulose me nā hydroxyprockl (-och2.och2hisks3) a me Mithyl (-och3)
     • ʻO ke kiʻekiʻe o ka hoʻololiʻana (DS) e hōʻike i ka helu maʻamau o nā hui hydroxyl i kohoʻia ma ke poʻo glucose ma ke kaula glucose ma ke kaula glucose ma ke kaula glucose.
2. CarboxyMethyl cellulouse(Cmc):
   • Kūlana:
     • Ua hanaʻiaʻo CMC e ka hoʻolaunaʻana i ka MREBOXYMYLL
     • ʻO nā huiʻo CarboxyMyl i nā hui wai wela i ka wai momona a me keʻano anionic i ka kaula cellouse.
3. Hydroxythyl Cellulouse (hec):
   • Kūlana:
     • Ua kiʻiʻiaʻo Hec e ka hoʻopiliʻana i nā pūʻulu hydroxyl o ka cellulose me ka hydropexyl (-och2ch2h).
     • Hōʻike ia i ka hoʻomaikaʻiʻana i ka wai momona a me nā waiwai nui.
4. ʻO Mathyl Cellulose (MC):
   • Kūlana:
     • Ua hanaʻiaʻo MC ma ka hoʻolaunaʻana i ka Momyl (-Och3)
     • Hoʻohana pinepineʻia no kona mau wai wai a me nā mea hana kiʻi kiʻi kiʻi.
5. Estyl cellulouse (ec):
   • Kūlana:
     • E hoʻopaʻaʻiaʻo EC e ka hoʻopiliʻana i nā pūʻulu hydroxyl o nā cellouse me nā hui etyl (-oc2h5).
     • ʻIkeʻia ia no kona inlibulity i loko o ka wai a hoʻohana pinepineʻia i ka hanaʻana o nā lole a me nā kiʻiʻoniʻoni.
6. Hydroxyproopsl celllouse (hpc):
   • Kūlana:
     • Ua loaʻa iā HPC ma ka hoʻolahaʻana i ka hydroxyprooppppppppppppppppppppppppppppppppp3) mau pūʻulu i nā hui hydroxyl o nā cellouse.
     • Hoʻohanaʻia ia ma keʻano he binder, kiʻi kiʻi kiʻi, a me keʻano ciscosity.

ʻO nāʻano kiko'ī kiko'ī no kēlā me kēia cellulose eter derivative e pili ana i keʻano a me ke kiʻekiʻe o ka spebina i hōʻikeʻia i ke kaʻina hoʻololi hoʻololi. ʻO ka hoʻomakaʻana o kēia mau pūʻulu eter i nā hui i nā waiwai kiko'ī i kēlā me kēia cellolose eter, e hana ana iā lākou no nā noi likeʻole.
