Cellulose ethershe mau polymers hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa mai ka cellulose, ka polymer nui loa i ke ʻano. No nā makahiki ʻoi aku ma mua o 60, ua hana nui kēia mau huahana versatile i ka nui o nā noi, mai nā huahana kūkulu, seramika a me nā pena i nā meaʻai, nā mea hoʻonaninani a me nā lāʻau lapaʻau.
No nā huahana hana, hana nā cellulose ethers e like me nā mānoanoa, nā mea hoʻopili, nā mea hana kiʻiʻoniʻoni a me nā mea mālama wai. Hana pū lākou ma ke ʻano he kōkua hoʻokuʻu, surfactants, lubricants, colloids pale a me nā emulsifers. Eia kekahi, ʻo nā wai wai o kekahi mau cellulose ethers thermally gel, kahi waiwai kūʻokoʻa e pāʻani ana i kahi hana koʻikoʻi i kahi kahaha.
ʻano hoʻohana like ʻole. ʻAʻole loaʻa kēia hui waiwai o nā waiwai i loko o kekahi polymer hiki ke hoʻoheheʻe wai.
ʻO ka ʻoiaʻiʻo o ka nui o nā waiwai pono i ka manawa like a hana pinepine i ka hui pū ʻana hiki ke lilo i mea waiwai waiwai nui. Ma nā noi he nui, ʻelua, ʻekolu a ʻoi aku paha nā mea e pono ai e hana i ka hana like i hana ʻia e kahi huahana cellulose ether hoʻokahi. Eia kekahi, ʻoi aku ka maikaʻi o ka cellulose ethers, pinepine
e hāʻawi ana i ka hana maikaʻi loa ma kahi haʻahaʻa haʻahaʻa ma mua o ka mea i koi ʻia me nā polymers hiki ke hoʻoheheʻe wai.
Hāʻawi ʻo Dow Construction Chemical i kahi ākea o nā huahana cellulosic, me ka methyl cellulose, hydroxyethyl cellulose a me carboxymethyl cellulose. Hoʻohana nui ʻia nā methyl cellulose ethers no nā noi he nui i ka hale a me ka ʻoihana hana.
Kemika o Cellulose Ethers
Hāʻawi kā mākou ʻoihana i nā cellulose ethers i ʻehā mau ʻano kumu:
1.Hydroxyethyl methyl cellulose (HEMC/MHEC)
2.Hydroxypropyl methyl cellulose (HPMC,MC)
3.Hydroxyethyl cellulose (HEC)
4. Carboxy methyl cellulose (CMC)
Loaʻa i nā ʻano ʻelua ka iwi kuamoʻo polymeric o cellulose, kahi waiʻaʻaʻa maoli i loaʻa kahi ʻano hana hou o nā ʻāpana anhydroglucose. I ka wā o ka hana ʻana i nā cellulose ethers, ua hoʻomehana ʻia nā fiber cellulose me kahi hopena caustic, a laila, mālama ʻia me ka methyl chloride, a me ka propylene oxide a i ʻole ethylene oxide, e hāʻawi ana i ka hydroxypropyl methyl cellulose a i ʻole hydroxyethyl methyl cellulose. Hoʻomaʻemaʻe ʻia ka huahana fibrous reaction a hoʻoheheʻe ʻia a hiki i ka pauka maikaʻi.
Ua hoʻokumu pū ʻia nā huahana kūikawā e hoʻokō i nā koi o nā ʻoihana kikoʻī.
Loaʻa kā mākou huahana cellulose ether i ʻekolu mau ʻano like ʻole: ka pauka, ka pauka i mālama ʻia ma luna a me ka granular. ʻO ke ʻano o ka huahana i hoʻonohonoho ʻia e hoʻololi i ke ʻano e koho ai. I ka hapanui o nā noi maloʻo, hoʻohana pinepine ʻia ka pauka i hoʻomaʻamaʻa ʻole ʻia, akā no nā noi hoʻohui mākaukau, kahi i hoʻohui pono ʻia ai ka pauka cellulosic i ka wai, ʻoi aku ka maikaʻi o ka pauka i mālama ʻia i ka ʻili a i ʻole nā ʻano granular.
Na Waiwai Nui
ʻO nā waiwai maʻamau maʻamau i kā mākou cellulose ethers i helu ʻia ma aneʻi. Hōʻike kēlā me kēia huahana i kēia mau waiwai i nā pae like ʻole a loaʻa paha
