Ethyl Cellulose- EC mea hoʻolako

ʻO ka Ethyl cellulose he polymer hikiʻole ke hoʻololi i ka wai i loaʻa mai ka cellulose, he biopolymer maoli i loaʻa i loko o nā paia o nā mea kanu. Hoʻohana nui ʻia ia i nā ʻoihana like ʻole, me nā lāʻau lapaʻau, nā meaʻai, a me ka mālama pilikino, ma muli o kāna mau waiwai kūʻokoʻa, me ka solubility, ka hiki ke hana kiʻiʻoniʻoni, a me ka haʻahaʻa haʻahaʻa. E kūkākūkā kēia ʻatikala i nā waiwai, synthesis, a me nā noi o ka ethyl cellulose.

ʻO nā waiwai o ka Ethyl Cellulose ʻO Ethyl cellulose kahi mea thermoplastic i hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe, e like me ka ethanol, akā hiki ʻole ke hoʻoheheʻe ʻia i ka wai. Hiki ke hoʻololi ʻia ka solubility o ka ethyl cellulose ma ka hoʻololi ʻana i kona degere o ka hoʻololi ʻana, e pili ana i ka helu o nā pūʻulu ethyl i kēlā me kēia ʻāpana glucose i loko o ka molekele cellulose. ʻO ka Ethyl cellulose me kahi kūlana kiʻekiʻe o ka hoʻololi ʻana he mea hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik, aʻo ka poʻe me ka degere haʻahaʻa o ka hoʻololi ʻana ʻoi aku ka liʻiliʻi.

ʻIke ʻia ʻo Ethyl cellulose no kāna hana kiʻiʻoniʻoni maikaʻi loa a hiki ke hoʻohana ʻia no ka hana ʻana i kahi kiʻiʻoniʻoni paʻa. Hiki ke hoʻonui hou ʻia nā waiwai hana kiʻiʻoniʻoni o ka ethyl cellulose ma ka hoʻohui ʻana i nā plasticizers, e like me ka dibutyl phthalate a i ʻole triacetin, e hoʻonui ai i ka maʻalahi a me ka elasticity o ke kiʻi. Hoʻohana pinepine ʻia nā kiʻi ʻoniʻoni Ethyl cellulose i ka ʻoihana lāʻau lapaʻau e like me nā uhi no nā papa, capsules, a me nā granules.

Synthesis of Ethyl Cellulose Hoʻopili ʻia ka Ethyl cellulose ma ka hana ʻana i ka cellulose me ka ethyl chloride i mua o kahi kumu, e like me ka sodium hydroxide a i ʻole potassium hydroxide. ʻO ka hopena e pili ana i ka hoʻololi ʻana o nā pūʻulu hydroxyl i loko o ka molekele cellulose me nā pūʻulu ethyl, ka hopena i ka hoʻokumu ʻana o ka ethyl cellulose. Hiki ke ho'omalu 'ia ke degere o ka ho'ololi 'ana ma o ka ho'oponopono 'ana i nā kūlana ho'ololi, e like me ka mana'o o nā reactants a me ka manawa pane.

Noi o Ethyl Cellulose Pharmaceuticals: Hoʻohana nui ʻia ʻo Ethyl cellulose i ka ʻoihana lāʻau lapaʻau ma muli o kona hiki ke hana kiʻiʻoniʻoni maikaʻi loa a me ka haʻahaʻa haʻahaʻa. Hoʻohana ʻia ia ma ke ʻano he mea uhi no nā papa, nā capsules, a me nā granules, e hoʻomaikaʻi ai i ko lākou kūpaʻa a pale iā lākou mai ka hoʻokaʻawale ʻana i ka ʻōpū o ka ʻōpū. Hiki ke hoʻohana ʻia ka uhi ʻana o Ethyl cellulose e kāohi i ka hoʻokuʻu ʻana o nā lāʻau lapaʻau ma o ka hoʻololi ʻana i kā lākou disolution rate.

Meaʻai: Hoʻohana ʻia ʻo Ethyl cellulose ma ke ʻano he mea hoʻohui meaʻai e hoʻomaikaʻi i ke ʻano a me ke kūpaʻa o nā meaʻai. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he mānoanoa, mea hoʻopaʻa, a me ka stabilizer i nā meaʻai i hoʻoponopono ʻia, e like me nā kīʻaha, nā lole, a me nā meaʻai i kālua ʻia. Hiki ke hoʻohana ʻia ka Ethyl cellulose ma ke ʻano he uhi no nā huaʻai a me nā mea kanu e hoʻolōʻihi i ko lākou ola ʻana a pale i ka pala.

Hoʻohana pilikino: Hoʻohana ʻia ʻo Ethyl cellulose i nā huahana mālama pilikino like ʻole, e like me nā mea hoʻonaninani, shampoos, a me nā lotions, ma muli o kona hiki ke hana kiʻiʻoniʻoni a me nā waiwai pale wai. Hoʻohana pinepine ʻia e like me ka mānoanoa a me ka stabilizer i nā mea hoʻonaninani a hiki ke hoʻohana ʻia ma ke ʻano he mea hana kiʻiʻoniʻoni i loko o nā lauoho lauoho a me nā huahana styling.

Nā mea hoʻohana ʻē aʻe: Hoʻohana ʻia ka Ethyl cellulose i nā noi ʻē aʻe, e like me nā inika, nā uhi, nā mea hoʻopili, a me nā pena. Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he mea hoʻopaʻa i nā uhi a me ka mānoanoa i nā inika. Hiki ke hoʻohana ʻia ʻo Ethyl cellulose ma ke ʻano he uhi pale wai no ka pepa a ma ke ʻano he mea hoʻopaʻa no nā seramika.

I ka hōʻuluʻulu ʻana, ʻo ka ethyl cellulose he polymer wai-inoluble i loaʻa mai ka cellulose i hoʻohana nui ʻia i nā ʻoihana like ʻole, me nā lāʻau lapaʻau, nā meaʻai, a me ka mālama pilikino. Ua ʻike ʻia ʻo ia no kona hiki ke hana kiʻiʻoniʻoni maikaʻi, haʻahaʻa haʻahaʻa, a me ka wai-kūpaʻa waiwai, kūpono ia no nā noi like ʻole.
