2. Moʻolelo hoʻomohala ʻoihana:
① Moʻolelo hoʻomohala o ka ʻoihana cellulose ether non-ionic: Ma 1905, ua ʻike ʻia ka etherification o cellulose no ka manawa mua ma ka honua, me ka hoʻohana ʻana i ka dimethyl sulfate a me ka cellulose alkali-swelled no ka methylation.Nonionic cellulose ethers ua patented e Lilienfeld ma 1912, a me Dreyfus (1914) a me Leuchs (1920) loaa ka wai-soluble a me ka aila cellulose ethers, pakahi.Ua hana ʻo Hubert i ka HEC i ka makahiki 1920. I nā makahiki 1920 mua, ua kūʻai ʻia ka carboxymethylcellulose ma Kelemānia.Mai 1937 a hiki i 1938, ua ʻike ʻo ʻAmelika i ka hana ʻenehana o MC a me HEC.Ma hope o 1945, ua hoʻonui wikiwiki ʻia ka hana ʻana o ka cellulose ether ma Western Europe, ʻAmelika Hui Pū ʻIa a me Iapana.Ma hope o hoʻokahi haneli mau makahiki o ka hoʻomohala ʻana, ua lilo ka non-ionic cellulose ether i mea kemika i hoʻohana mau ʻia ma ka honua.
Aia kekahi ʻokoʻa ma waena o nā ʻāina ulu a me nā ʻāina i kūkulu ʻia e pili ana i ka pae kaʻina hana a me nā kahua noi huahana o non-ionic cellulose ethers.Ma ke ʻano o ka ʻenehana hana, ʻo nā ʻāina i kūkulu ʻia e like me ʻEulopa, ʻAmelika ʻAmelika, a me Iapana i loaʻa i ka ʻenehana a me ka ʻenehana, a hana nui i nā huahana noi kiʻekiʻe e like me nā uhi, nā meaʻai, a me nā lāʻau lapaʻau;ʻO nā ʻāina e ulu nei he koi nui no CMC a me HPMC, a paʻakikī ka ʻenehana i ka hana ʻana i nā huahana cellulose ether me nā haʻahaʻa haʻahaʻa o ka hana nui, a ʻo ke kahua o nā mea kūkulu hale ka mākeke kūʻai nui.
Ma nā ʻōlelo o nā kahua noi, ua hoʻokumu nā ʻāina i kūkulu ʻia e like me ʻEulopa a me ʻAmelika Hui Pū ʻIa i kahi kaulahao ʻoihana piha a ʻoi loa no kā lākou huahana cellulose ether ma muli o nā kumu e like me ka hoʻomaka mua a me ka ikaika R&D ikaika, a ʻo nā noi i lalo e uhi i nā kahua he nui o ka. hoʻokele waiwai aupuni;ʻoiai e ulu ana nā ʻāina Ma muli o ka manawa hoʻomohala pōkole o ka ʻoihana cellulose ether, ʻoi aku ka liʻiliʻi o ka noi ma mua o nā ʻāina i kūkulu ʻia.Eia nō naʻe, me ka hoʻomaikaʻi lohi ʻana o ka pae hoʻomohala hoʻokele waiwai o nā ʻāina e ulu nei, ʻoi aku ka maikaʻi o ke kaulahao ʻoihana, a hoʻomau ka hoʻonui ʻia o ka noi.
②HEC moʻolelo hoʻomohala ʻoihana: HEC he hydroxyalkyl cellulose koʻikoʻi a me ka wai-soluble cellulose ether me ka nui o ka hana ma ka honua.
ʻO ka hoʻohana ʻana i ka wai ethylene oxide ma ke ʻano he etherification agent e hoʻomākaukau ai i ka HEC ua hana i kahi kaʻina hana hou no ka hana ʻana o ka cellulose ether.ʻO ka ʻenehana koʻikoʻi kūpono a me ka hiki ke hana i ka nui o nā mea hana kemika nui ma ʻEulopa, ʻAmelika, Iapana, a me South Korea.Ua hoʻomohala mua ʻia ʻo HEC ma koʻu ʻāina i ka makahiki 1977 e Wuxi Chemical Research Institute a me Harbin Chemical No.Eia nō naʻe, ma muli o nā kumu e like me ka ʻenehana i hope a me ka maikaʻi ʻole o ka maikaʻi o ka huahana, ʻaʻole i hoʻokumu i ka hoʻokūkū kūpono me nā mea hana honua.I kēia mau makahiki i hala iho nei, ua haki nā mea hana hale e like me Yin Ying New Materials i nā pale ʻenehana, hoʻomaikaʻi i nā kaʻina hana, hoʻokumu i nā mana hana nui no nā huahana paʻa paʻa, a ua hoʻokomo ʻia i loko o ke ʻano o ke kūʻai ʻana e nā mea hana o lalo, e hoʻomau mau ana i ke kaʻina hana o ka home. pani.
3. Nā hōʻailona hana nui a me ka hoʻomākaukau ʻana o ka cellulose ether non-ionic:
(1) Nā hōʻailona hana nui o ka non-ionic cellulose ether: nā hōʻailona hana nui o nā huahana cellulose ether non-ionic he degere o ka hoʻololi a me ka viscosity, etc.
(2) Non-ionic cellulose ether hoʻomākaukau ʻenehana: Ma ke kaʻina hana o ka cellulose ether, ʻo ka cellulose maka a me ka cellulose ether i hana mua ʻia i loko o kahi kūlana multiphase hui.Ma muli o ke ʻano o ka hoʻoulu ʻana, ka lākiō waiwai a me ke ʻano maka, a me nā mea ʻē aʻe, ʻo ka cellulose ethers i loaʻa ma ka heterogeneous reactions he like ʻole, a aia nā ʻokoʻa i ke kūlana, ka nui a me ka maʻemaʻe huahana o nā pūʻulu ether, ʻo ia hoʻi, ka loaʻa. Aia nā cellulose ethers ma nā kaulahao macromolecular cellulose like ʻole, ʻO ka helu a me ka hāʻawi ʻana o nā pani i nā pūʻulu apo glucose like ʻole ma ka macromolecule cellulose like a me C (2), C (3) a me C (6) ma kēlā me kēia pūʻulu apo cellulose.Pehea e hoʻoponopono ai i ka pilikia o ka hoʻololi ʻole ʻana ke kī i ka hoʻoponopono ʻana i ke kaʻina hana o ka cellulose ether.
ʻO ka hōʻuluʻulu ʻana, ka mālama ʻana i nā mea maka, alkaliization, etherification, holoi holoi a me nā kaʻina hana ʻē aʻe i ke kaʻina hana o ka non-ionic cellulose ether i nā koi kiʻekiʻe no ka ʻenehana hoʻomākaukau, ka mana kaʻina a me nā lako hana;i ka manawa like, ʻo ka hana nui o nā huahana kiʻekiʻe e koi i ka ʻike waiwai a me ka hiki ke hoʻonohonoho pono.
