ʻO ka 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 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
ka uhi ʻana
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 paʻa, a me ka hana paʻa wai maikaʻi;ʻO ka cellulose ether ka mea kūpono loa e hoʻolako i kēia mau waiwai.
hale hoʻolālā
Ma ke kahua o ka ʻoihana kūkulu, hoʻohana ʻia ʻo HEC ma ke ʻano he mea hoʻohui i nā mea e like me nā mea paʻa, ka ʻuala (me ka asphalt), nā tile i hoʻopili ʻia a me nā mea caulking.
Hiki i nā mea hoʻohui ke hoʻonui i ka viscosity a me ka mānoanoa o nā mea kūkulu hale, hoʻomaikaʻi i ka adhesion, lubricity, a me ka paʻa ʻana o ka wai, hoʻonui i ka ikaika flexural o nā ʻāpana a i ʻole nā ʻāpana, hoʻomaikaʻi i ka shrinkage, a pale i nā māwae.
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 kū ʻana o ka abrasion, dyeability, ke 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, ka mea e hanu ai lākou a hōʻemi i ka static. uila.
kemika i kēlā me kēia lā
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.
hana pepa
Ma ke kahua o ka hana pepa, hiki ke hoʻohana ʻia ʻo HEC ma ke ʻano he mea nui, mea hoʻoikaika a me ka hoʻololi pepa
ʻeli ʻaila
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
mahiʻai
Hiki i ka Hydroxyethyl cellulose (HEC) ke hoʻokuʻu pono i nā lāʻau ʻawaʻawa paʻa i loko o nā pulu wai.
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;i mea hoʻopili i ka hana hou ʻana i nā lau paka.
ke ahi
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.
ke kalaiwa ana
Hiki i ka Hydroxyethylcellulose ke hoʻomaikaʻi i ka ikaika pulu a me ka emi ʻana o ke one sima a me nā ʻōnaehana one sodium silicate.
Microscopy
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.
Mea mānoanoa i nā wai paʻakai kiʻekiʻe i hoʻohana ʻia no ka hana kiʻiʻoniʻoni.
pena paipu fluorescent
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.
Electroplating a me Electrolysis
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.
seramika
Hiki ke hoʻohana ʻia no ka hoʻokumu ʻana i nā mea hoʻopili ikaika kiʻekiʻe no nā seramika.
uwea
ʻO nā mea hoʻopau wai e pale i ka makū mai ke komo ʻana i nā uwea pōʻino.
