Nā noi no ka Hydroxyethyl Cellulose (HEC)

Hydroxyethyl cellulose (HEC)he ether cellulose non-ionic 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, ka kemika i kēlā me kēia lā, ka pepa, ka ʻaila ʻaila a me nā ʻoihana ʻē aʻe.

Nā wahi noi nui:

1.Paint:Water-based wai he wai viscous i hoʻokumu ʻia me nā mea hoʻoheheʻe organik a i ʻole ka wai e pili ana i 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 paʻa, a me ka hana paʻa wai maikaʻi; ʻO ka cellulose ether ka mea kūpono loa e hoʻolako i kēia mau waiwai.

2.Construction：Ma ke kahua o ka ʻoihana hana, 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 paʻa wai. E hoʻonui i ka ikaika flexural o nā ʻāpana a i ʻole nā ​​​​ʻāpana, hoʻomaikaʻi i ka emi ʻana, a pale i nā māwae lihi.

3.Textile：Hec-treated cotton, synthetic fibers or blends hoʻomaikaʻi i ko lākou mau waiwai e like me ka abrasion resistance, dyeability, fire resistance and stain resistance, a me ka hoʻomaikaʻi ʻana i ko lākou kino kūpaʻa (shrinkage) a me ka lōʻihi, ʻoi aku ka nui o nā fibers synthetic, ka mea e hanu ai a hoʻemi i ka uila static.

4.Daily chemical: Cellulose ether he 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 mea hoʻololi pepa.

6.Oil drilling:HEC ua hoʻohana nui ʻia 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:

HEChiki ke pāʻani i ke kuleana 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 silicate sodium. Hiki ke hoʻohana ʻia ka Hydroxyethyl cellulose 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.
