ʻO ka Ethylcellulose kahi mea hoʻopili i hoʻohana nui ʻia i nā ʻoihana like ʻole, ʻoi loa i nā lāʻau lapaʻau, nā meaʻai, nā uhi a me nā mea hoʻonaninani.
Hoʻomaka i ka ethyl cellulose
ʻO ka Ethylcellulose he mea ia o ka cellulose, he polymer maoli i loaʻa i loko o nā paia o nā mea kanu.Hana ʻia ia e ka hopena ethylation o cellulose me ka ethyl chloride a i ʻole ethylene oxide.Hāʻawi kēia hoʻololi i nā waiwai kūʻokoʻa, kūpono ia no nā noi like ʻole, ʻoi aku hoʻi ma ke ʻano he adhesive i nā ʻoihana like ʻole.
Nā hiʻohiʻona o ka ethylcellulose
Hoʻolālā Kemika: Aia ka Ethylcellulose i nā ʻāpana hou o ka anhydroglucose i hoʻopili ʻia e nā paʻa β(1→4) glycosidic.Hoʻololi ka ethylation o cellulose i kekahi mau pūʻulu hydroxyl (-OH) me nā hui ethoxy (-OCH2CH3).
Solubility: ʻAʻole hiki ke hoʻoheheʻe ʻia ka Ethylcellulose i ka wai, akā hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol, acetone, toluene, a me ka chloroform.He kūpono kēia waiwai no nā noi e koi ana i ka pale wai.
Hiki ke hana kiʻiʻoniʻoni: Hiki i ka Ethyl cellulose ke hana i kahi kiʻiʻoniʻoni maʻalahi a maʻalahi ma hope o ka hoʻoheheʻe ʻia ʻana i loko o kahi solvent organik kūpono.Loaʻa i kēia mau kiʻiʻoniʻoni maikaʻi ka ikaika mechanical a me nā mea pale.
Thermoplasticity: Hōʻike ʻo Ethylcellulose i ke ʻano thermoplastic, e maʻalahi ai ka hana ʻana me ka hoʻohana ʻana i nā ʻenehana e like me ka extrusion, injection molding, a me ka hoʻoheheʻe ʻana.
Hoʻohālikelike: Ua kūpono ʻo Ethylcellulose me nā ʻano polymers ʻē aʻe, plasticizers a me nā mea hoʻohui, kūpono ia no ka hoʻohana ʻana i nā ʻano hana like ʻole.
Hoʻohana i ka ethyl cellulose ma ke ʻano he mea hoʻopili
1. ʻoihana lāʻau lapaʻau
I loko o nā hana lāʻau lapaʻau, hana ka ethylcellulose ma ke ʻano he mea hoʻopaʻa i ka hana papa.Kōkua ia i ka hoʻopaʻa ʻana i ka lāʻau lapaʻau ikaika (API) a me nā mea kōkua, e hōʻoiaʻiʻo ana i ka pono o ka papa ʻaina a me ka lokahi.Eia kekahi, hoʻohana pū ʻia ka ethylcellulose i nā ʻano hoʻokuʻu hoʻokuʻu ʻia e koi ai i ka hoʻokuʻu ʻana i ka lāʻau.
2. ʻOihana meaʻai
Hoʻohana ʻia ka Ethylcellulose ma ke ʻano he mea hoʻopaʻa, mānoanoa, a me ka stabilizer i nā meaʻai.Hoʻohana ʻia ia i ka uhi ʻana o nā huaʻai, nā mea kanu a me nā confectionery e hoʻomaikaʻi i ko lākou helehelena a me ke ola papa.Hāʻawi ka Ethylcellulose coating i kahi pale pale i ka makū, nā kinoea a me nā mea haumia.
3. Ka uhi a me ka inika
I loko o ka ʻoihana uhi a me ka ʻīnika, hoʻohana ʻia ka ethylcellulose ma ke ʻano he mea hoʻopaʻa i nā pena, nā varnish, nā varnish, a me ka paʻi ʻana i ka inika.Hāʻawi ia i kēia mau coatings adhesion, hiki ke maʻalahi a me ka pale wai, e hoʻomaikaʻi ai i kā lākou hana a me ka lōʻihi.
4. Nā mea hoʻonani
Hoʻohana ʻia ʻo Ethylcellulose ma ke ʻano he mānoanoa a me ka stabilizer i nā mea hoʻonaninani e like me nā creams, lotions a me nā huahana mālama lauoho.Kōkua ia i ka hoʻokō ʻana i ke ʻano i makemake ʻia, ka kūlike a me ka viscosity i loko o nā mea hoʻonaninani.
5. Nā noi hana
I nā noi ʻoihana, hoʻohana ʻia ka ethylcellulose ma ke ʻano he mea hoʻopaʻa i ka hana ʻana i nā mea seramika, abrasives a me nā composites.Kōkua ia i ka hana ʻana i nā kino ʻōmaʻomaʻo a mālama i nā waiwai rheological o nā pastes a me nā slurries.
Hoʻohui ʻia o ka ethylcellulose
ʻO ka synthesis o ka ethylcellulose e pili ana i ka hopena o ka cellulose me kahi mea ethylating ma lalo o nā kūlana hoʻomalu.Hoʻokō pinepine ʻia ka hopena ethylation i mua o kahi catalyst e like me ka waikawa a i ʻole ke kumu e hāpai i ka hoʻololi ʻana o nā pūʻulu hydroxyl me nā hui ethoxy.Hōʻike ka degere o ka hoʻololi ʻana (DS) i ka helu awelika o nā pūʻulu ethoxy i kēlā me kēia ʻāpana glucose i ke kaulahao polymer a hiki ke hoʻomalu ʻia ma ka hoʻoponopono ʻana i nā ʻāpana hoʻohālikelike e like me ka manawa pane, ka mahana, a me ka ratio molar o nā reactants.
ʻO nā pono o ka ethylcellulose ma ke ʻano he mea hoʻopili
Versatility: Hōʻike ʻo Ethylcellulose i ka versatility ma ke ʻano o ka solubility, compatibility a me ka hiki ke hana kiʻiʻoniʻoni, kūpono ia no kahi ākea o nā noi ma nā ʻoihana.
Pale Wai: ʻAʻole hiki ke hoʻoheheʻe ʻia ka Ethylcellulose i loko o ka wai, e lilo ia i mea koho maikaʻi loa no nā ʻano hana e pono ai ke kūpaʻa wai, e like me nā uhi, pena, a me nā lāʻau lapaʻau hoʻokuʻu ʻia.
Thermoplasticity: ʻO ke ʻano thermoplastic o ka ethylcellulose e hiki ai ke hana maʻalahi me ka hoʻohana ʻana i nā ʻenehana thermoplastic kuʻuna, e ʻae ana i nā kaʻina hana hana kumu kūʻai.
Biocompatibility: Ethylcellulose ka mea maʻamau i ʻike ʻia he palekana (GRAS) e nā keʻena hoʻoponopono no ka hoʻohana ʻana i nā noi meaʻai a me nā lāʻau lapaʻau, e hōʻoiaʻiʻo ana i kona biocompatibility a me ka palekana o ka mea kūʻai.
Hoʻokuʻu hoʻokuʻu ʻia: Hoʻohana nui ʻia ka Ethylcellulose i ka ʻoihana lāʻau lapaʻau e hoʻomohala i nā palapala hoʻokuʻu hoʻokuʻu ʻia e hāʻawi i ka mana pololei o ka helu hoʻokuʻu lāʻau.
Hoʻohana ʻia ʻo Ethylcellulose ma ke ʻano he multifunctional binder me nā ʻano noi like ʻole i nā lāʻau lapaʻau, nā meaʻai, nā uhi, nā mea hoʻonaninani a me nā ʻoihana ʻoihana.ʻO kāna mau waiwai kūʻokoʻa, me ka solubility, ka hiki ke hana kiʻiʻoniʻoni a me ka hoʻohālikelike ʻana, e lilo ia i mea waiwai nui i nā ʻano hana like ʻole.Loaʻa ka synthesis o ka ethylcellulose e ka ethylating cellulose ma lalo o nā kūlana i hoʻomalu ʻia, ka hopena i nā mea me nā waiwai i kūpono i nā noi kikoʻī.Me kona kūpaʻa wai, thermoplasticity a me ka hoʻokuʻu ʻia ʻana, hoʻomau ka ethylcellulose i ka hana koʻikoʻi i ka hoʻomaikaʻi ʻana i ka hana a me ka hana o nā huahana ma kahi ākea o nā ʻoihana.
