He aha ka Hydroxyethyl Cellulose e hoʻohana ai?

Hydroxyethyl cellulose(HEC) he non-ionic cellulose ether i hana ʻia mai ka cellulose material polymer maoli ma o ke ʻano o ka etherification. He mea ʻala ʻole, ʻono ʻole, ʻaʻohe mea ʻawaʻawa keʻokeʻo a i ʻole granule, hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu e hana i kahi hopena viscous akaka, a ʻaʻole pili ka dissolution i ka waiwai pH. He mānoanoa, hoʻopaʻa, dispersing, emulsifying, film-forming, suspending, adsorbing, surface active, moisture-retaining a me ka paʻakai paʻakai. Hoʻohana nui ʻia i ka pena, ke kūkulu ʻana, ka textile, kemika o kēlā me kēia lā, ka pepa, ka ʻaila ʻaila a me nā ʻoihana ʻē aʻe.

Nā wahi noi nui：

1. Pena：ʻO ka pena i hoʻopaʻa ʻia i ka wai he wai ʻeleʻele i hoʻokumu ʻia me nā solvents organik a i ʻole ka wai i hoʻokumu ʻia ma ka resin, a i ʻole aila, a i ʻole emulsion, me ka hoʻohui ʻana i nā mea hoʻohui like. ʻO nā uhi wai me ka hana maikaʻi loa e loaʻa i ka hana maikaʻi loa, ka mana huna maikaʻi, ka hoʻopili ʻana i ka uhi ikaika, a me ka hana paʻa wai maikaʻi; ʻO ka cellulose ether ka mea kūpono loa e hoʻolako i kēia mau waiwai.

2.Ckuhikuhi：Ma ke kahua o ka ʻoihana kūkulu, hoʻohana ʻia ʻo HEC ma ke ʻano he mea hoʻohui no nā mea e like me nā mea pā, ka pā (me ka asphalt), nā tile i hoʻopili ʻia a me nā mea caulking, hiki ke hoʻonui i ka viscosity a me ka mānoanoa o nā mea hale, hoʻomaikaʻi i ka adhesion, lubricity, a me ka wai. ka paa ana. Hoʻonui i ka ikaika flexural o nā ʻāpana a i ʻole nā ​​ʻāpana, hoʻomaikaʻi i ka emi ʻana, a pale aku i nā māwae lihi.

3.Textile：ʻO ka pulupulu i mālama ʻia e ka HEC, nā fibers synthetic a i ʻole nā ​​hui ʻana e hoʻomaikaʻi i kā lākou mau waiwai e like me ke kūpaʻa abrasion, dyeability, pale ahi a me ka pale ʻana i ka ʻili, a me ka hoʻomaikaʻi ʻana i ko lākou kino kūpaʻa (shrinkage) a me ka lōʻihi, ʻoi aku hoʻi no nā fibers synthetic, kahi e hanu ai lākou a hōʻemi i ka static. uila.

4.Daily kemikala：ʻO ka cellulose ether kahi mea hoʻohui pono i nā huahana kemika i kēlā me kēia lā. ʻAʻole hiki iā ia ke hoʻomaikaʻi wale i ka viscosity o ka wai a i ʻole emulsion cosmetics, akā hoʻomaikaʻi hoʻi i ka hoʻopuehu a me ka paʻa ʻana o ka foam.

5.Pepa：Ma ke kahua o ka hana pepa, hiki ke hoʻohana ʻia ʻo HEC ma ke ʻano he ʻano nui, mea hoʻoikaika ikaika a me ka hoʻololi pepa.

6.Oil drilling：Hoʻohana nui ʻia ʻo HEC ma ke ʻano he mānoanoa a me ka hoʻopaʻa ʻana i ke kaʻina hana ʻaila. He mea ʻaila maikaʻi ia. Ua hoʻohana nui ʻia ia i ka ʻeli ʻana, ka hoʻopiha maikaʻi ʻana, ka hoʻomaʻamaʻa ʻana a me nā hana ʻaila ʻē aʻe ma nā ʻāina ʻē i ka makahiki 1960.

Nā kahua noi ʻē aʻe：

Hiki i ka HEC ke hoʻokō i ka hana o ka hoʻopili ʻana i ka lāʻau ʻawaʻawa i nā lau i ka hana ʻana; Hiki ke hoʻohana ʻia ʻo HEC ma ke ʻano he mānoanoa no nā emulsion spray e hōʻemi i ka neʻe ʻana o ka lāʻau, ma laila e hoʻonui ai i ka hopena o ka hoʻohana ʻana i ka foliar spraying. Hiki nō hoʻi ke hoʻohana ʻia ʻo HEC ma ke ʻano he mea hana kiʻiʻoniʻoni i loko o nā mea hoʻopili hua; ma ke ʻano he mea hoʻopaʻa i ka hana hou ʻana i nā lau paka. Hiki ke hoʻohana ʻia ʻo Hydroxyethyl cellulose i mea hoʻohui e hoʻonui i ka hana uhi o nā mea ahi ahi, a ua hoʻohana nui ʻia i ka hoʻomākaukau ʻana i nā "thickeners" ahi. Hiki i ka Hydroxyethyl cellulose ke hoʻomaikaʻi i ka ikaika pulu a me ka emi ʻana o ke one sima a me nā ʻōnaehana one sodium silicate.Hydroxyethyl cellulose hiki ke hoʻohana i ka hana ʻana i nā kiʻiʻoniʻoni a ma ke ʻano he dispersant i ka hana ʻana i nā paheʻe microscopic. Mānoanoa i loko o nā wai me nā paʻakai kiʻekiʻe i hoʻohana ʻia i ka hana kiʻiʻoniʻoni. Hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa a me ka dispersant paʻa no nā mea hana fluorescent i loko o nā uhi ʻili fluorescent. Hiki iā ia ke pale i ka colloid mai ka mana o ka electrolyte concentration; Hiki i ka hydroxyethyl cellulose ke hoʻoikaika i ka hoʻopaʻa like ʻana i ka hoʻonā cadmium plating. Hiki ke hoʻohana ʻia no ka hoʻokumu ʻana i nā mea hoʻopili ikaika kiʻekiʻe no nā seramika. ʻO nā mea hoʻopau wai e pale i ka makū mai ke komo ʻana i nā uwea pōʻino.
