Pehea ʻoe e hana ai i ka ethyl cellulose?

ʻO ka Ethyl cellulose he polymer synthetic i hana ʻia mai ka cellulose, kahi mea hoʻohui i loaʻa i nā mea kanu. He pauda keʻokeʻo, ʻala ʻole, ʻono ʻole i hiki ʻole ke hoʻoheheʻe ʻia i ka wai a me ka hapa nui o nā mea hoʻoheheʻe organik. Hoʻohana ʻia ʻo Ethyl cellulose EC i nā ʻano noi like ʻole, me ka uhi ʻana, nā adhesives, a me nā lāʻau lapaʻau.

ʻO ke kaʻina hana o ka hana ʻana i ka ethyl cellulose e pili ana i kekahi mau ʻanuʻu. ʻO ka hana mua ka loaʻa ʻana o ka cellulose, hiki ke loaʻa mai nā kumu mea kanu e like me ka pulupulu, ka lāʻau, a i ʻole ka ʻohe. A laila mālama ʻia ka cellulose me kahi waikawa ikaika, e like me ka sulfuric acid, e wāwahi i ka cellulose i loko o kāna mau molekele kō. Hoʻopili ʻia nā molekole kō me ka ethyl alcohol e hana i ka ethyl cellulose.

Hoʻomaʻemaʻe ʻia ka ethyl cellulose e kahi kaʻina i kapa ʻia ʻo fractional precipitation. Hoʻopili kēia i ka hoʻohui ʻana i kahi mea hoʻoheheʻe i ka solution ethyl cellulose, kahi e hoʻoheheʻe ai ka ethyl cellulose mai ka hopena. A laila ʻohi ʻia ka ethyl cellulose i hoʻomaloʻo ʻia.

ʻO ka hana hope loa o ka hoʻololi ʻana i ka ethyl cellulose maloʻo i loko o ka pauka. Hana ʻia kēia ma ka wili ʻana i ka ethyl cellulose i loko o kahi pauka maikaʻi. A laila, mākaukau ka pauda e hoʻohana i nā ʻano hana like ʻole.

ʻO ka Ethyl cellulose kahi mea maʻalahi i hiki ke hoʻohana ʻia i nā ʻano hana like ʻole. Hoʻohana ʻia ia i loko o nā uhi, adhesives, a me nā lāʻau lapaʻau, a hiki ke hoʻohana ʻia e hana i nā kiʻiʻoniʻoni, fibers, a me nā gels. Hoʻohana ʻia ia i ka hana ʻana i nā pena, nā inika, a me nā huahana ʻē aʻe. Hoʻohana ʻia ʻo Ethyl cellulose ma ke ʻano he mānoanoa i nā huahana meaʻai, a ma ke ʻano he stabilizer i nā mea hoʻonaninani.
