He aha ka hydroxyethyl cellulose i hana ʻia mai?

ʻO ka Hydroxyethyl cellulose (HEC) he polymer synthetic i loaʻa mai ka cellulose, kahi polysaccharide kūlohelohe i loaʻa i nā mea kanu. He pauka keʻokeʻo, hiki ke hoʻoheheʻe ʻia i ka wai i hoʻohana ʻia ma ke ʻano he mea mānoanoa, hoʻopaneʻe, a hoʻopaʻa i nā huahana like ʻole, me nā mea hoʻonaninani, nā lāʻau lapaʻau, nā detergents, a me nā huahana meaʻai.

Hana ʻia ʻo HEC ma o ka hana ʻana i ka cellulose me ka ethylene oxide, kahi hui kemika i loaʻa mai ka ethylene, kahi kinoea hydrocarbon. Hoʻopili ka ethylene oxide me nā pūʻulu hydroxyl ma nā molekole cellulose, e hana ana i nā loulou ether ma waena o nā molekole cellulose. Hoʻokumu kēia hopena i ka polymer me ke kaumaha molekala kiʻekiʻe ma mua o ka cellulose mua, a hāʻawi i ka polymer i kona mau waiwai hiki ke hoʻoheheʻe wai.

Hoʻohana ʻia ʻo HEC i nā huahana like ʻole, me nā mea hoʻonaninani, nā lāʻau lapaʻau, nā detergents, a me nā huahana meaʻai. I nā mea hoʻonaninani, hoʻohana ʻia ia ma ke ʻano he mānoanoa mānoanoa, suspending agent, a me stabilizer. I loko o nā lāʻau lapaʻau, hoʻohana ʻia ia ma ke ʻano he binder, disintegrant, a me ka suspending agent. I loko o nā mea holoi, hoʻohana ʻia ia e like me kahi mea mānoanoa, suspending agent, a stabilizer. I nā huahana meaʻai, hoʻohana ʻia ʻo ia ma ke ʻano he mea mānoanoa, mea hoʻokuʻu, a me ka stabilizer.

Hoʻohana pū ʻia ʻo HEC i ka ʻaila a me nā hana hoʻoheheʻe kinoea, kahi e hoʻohana ʻia ai e hoʻonui i ka viscosity o nā wai wili a e hōʻemi i ka nalowale o ka wai mai ka hoʻokumu ʻana. Hoʻohana ʻia ia i ka hana pepa, kahi e hoʻonui ai i ka ikaika a me ka ʻoʻoleʻa o ka pepa.

He mea ʻawaʻawa ʻole ʻo HEC, ʻaʻole hoʻonāukiuki, a ʻaʻole allergenic, e palekana no ka hoʻohana ʻana i nā huahana like ʻole. He biodegradable ia, e hoʻolilo iā ia i kahi koho pili kaiapuni.
