ʻO nā waiwai nui o ka hydroxyethyl cellulose he hiki ke hoʻoheheʻe ʻia i loko o ka wai anuanu a me ka wai wela, ʻaʻohe waiwai gel. Loaʻa iā ia ka laulā o ka degere pani, solubility a me ka viscosity, maikaʻi thermal stability (ma lalo o 140 ° C), a ʻaʻole hana i ka gelatin ma lalo o nā kūlana acidic. ka ua. Hiki i ka hydroxyethyl cellulose solution ke hana i kahi kiʻiʻoniʻoni, a loaʻa iā ia nā hiʻohiʻona o ke ʻano non-ionic ʻaʻole e launa pū me nā ion a loaʻa ka hoʻohālikelike maikaʻi.
① Hiki ke hoʻoheheʻe ʻia ka hydroxyethyl cellulose i loko o ka wai wela a i ʻole ka wai anuanu, ʻaʻole e hoʻoheheʻe ʻia i ka wela kiʻekiʻe a i ʻole ka paila ʻana. ka solubility a me ka viscosity, a me ka gelation non-thermal;
②Ka hoʻomanawanui ʻana i ka paʻakai: No ka mea ʻaʻole ionic, hiki iā ia ke noho pū me ka nui o nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, surfactants, a me nā paʻakai. No laila, ke hoʻohālikelike ʻia me ka ionic carboxymethyl cellulose (CMC), ʻoi aku ka maikaʻi o ka paʻakai hydroxyethyl cellulose.
③Ka paʻa wai, ka pae, a me nā waiwai hana kiʻiʻoniʻoni: ʻelua ʻoi aku ka nui o kona hiki ke mālama i ka wai ma mua o ka methyl cellulose, a he hoʻoponopono maikaʻi loa ia, nā waiwai hana kiʻiʻoniʻoni maikaʻi loa, ka mālama ʻana i ka wai, miscibility, a me ka pale ʻana i ka wahine colloid.
Hoʻohana i ka hydroxyethyl cellulose
ʻO ka hydroxyethyl cellulose kahi huahana cellulose ether non-ionic wai, i hoʻohana nui ʻia i nā hale kūkulu hale, petroleum, polymer polymerization, lāʻau lapaʻau, hoʻohana i kēlā me kēia lā, ka pepa a me ka inika, ka lole, nā seramika, ke kūkulu ʻana, ka mahiʻai a me nā ʻoihana ʻē aʻe. Loaʻa iā ia nā hana o ka mānoanoa, hoʻopaʻa, emulsifying, dispersing a stabilizing, a hiki ke mālama i ka wai, hana i kahi kiʻiʻoniʻoni a hāʻawi i kahi hopena colloid pale. Hiki ke hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela, a hiki ke hāʻawi i kahi hoʻonā me kahi ākea o ka viscosity. He mea ulu ia i nā makahiki i hala iho nei. ʻO kekahi o ka cellulose ethers wikiwiki.
pena latex
ʻO Hydroxyethyl cellulose ka mānoanoa maʻamau i hoʻohana ʻia i nā pena latex. Ma kahi o ka pena latex mānoanoa, hiki iā ia ke emulsify, hoʻopuehu, hoʻopaʻa a mālama i ka wai. Hōʻike ʻia ia e ka hopena mānoanoa kupaianaha, hoʻomohala kala maikaʻi, hana kiʻiʻoniʻoni a me ka mālama paʻa. ʻO ka Hydroxyethyl cellulose kahi mea ionic cellulose derivative hiki ke hoʻohana ʻia i kahi ākea pH ākea. He kūpono maikaʻi me nā mea ʻē aʻe i loko o ka ʻāpana (e like me nā puaʻa, nā mea hoʻohui, nā mea hoʻopiha a me nā paʻakai). ʻO nā uhi i mānoanoa ʻia me ka hydroxyethyl cellulose he rheology maikaʻi ma nā ʻano ʻoki like ʻole a he pseudoplastic. Hiki ke hoʻohana ʻia nā ʻano hana e like me ka uhi ʻana i ka pulupulu, ka ʻili ʻili a me ka uhi ʻana. ʻO ke kūkulu maikaʻi ʻana, ʻaʻole maʻalahi e kulu, sag a splash, a me ka waiwai pae maikaʻi.
Polymerization
ʻO ka Hydroxyethyl cellulose nā hana o ka dispersing, emulsifying, suspending and stabilizing in the polymerization or copolymerization parts of synthetic resins, a hiki ke hoʻohana ʻia ma ke ʻano he colloid pale. Hōʻike ʻia ia e ka hiki ke hoʻopuehu ikaika, ʻeleʻele ʻeleʻele "kiʻiʻoniʻoni", ka nui o ka nui o ka ʻāpana, ke ʻano o nā ʻāpana like ʻole, ke ʻano ʻokoʻa, ka wai maikaʻi, ka ʻike hua kiʻekiʻe a me ka hana maʻalahi. No ka mea hiki ke hoʻoheheʻe ʻia ka hydroxyethyl cellulose i ka wai anuanu a me ka wai wela, a ʻaʻohe wahi wela o ka gelation, ʻoi aku ka maikaʻi no nā ʻano like ʻole polymerization.
ʻO nā waiwai kino koʻikoʻi e noiʻi ai i ka maikaʻi o ka dispersant ʻo ia ka ʻili (a i ʻole interfacial), ka ikaika interfacial a me ka mahana gelation o kāna ʻano wai. He kūpono kēia mau waiwai o ka hydroxyethyl cellulose no ka polymerization a i ʻole copolymerization o nā resins synthetic.
Hiki i ka Hydroxyethyl cellulose ke hoʻopili maikaʻi me nā eter cellulose hiki ke hoʻoheheʻe wai a me PVA. Hiki ke loaʻa i ka ʻōnaehana composite i hoʻokumu ʻia ka hopena piha o ke aʻo ʻana mai kekahi i kekahi. ʻO nā huahana resin i hana ʻia ma hope o ka hui ʻana ʻaʻole wale ka maikaʻi o ka maikaʻi, akā e hōʻemi hoʻi i ka poho waiwai.
ʻeli ʻaila
I ka ʻaila ʻaila a me ka hana ʻana, hoʻohana nui ʻia ka hydroxyethyl cellulose kiʻekiʻe ma ke ʻano he mānoanoa no ka hoʻopiha wai a me ka hoʻopau ʻana i ka wai. Hoʻohana ʻia ka hydroxyethyl cellulose haʻahaʻa haʻahaʻa e like me ka hoʻemi ʻana o ka wai. I loko o nā ʻōpala like ʻole i koi ʻia no ka ʻeli ʻana, ka hoʻopau maikaʻi ʻana, ka hoʻomaʻamaʻa maikaʻi ʻana a me ka hana ʻoki ʻana, hoʻohana ʻia ka hydroxyethyl cellulose ma ke ʻano he mānoanoa e loaʻa ai ka wai maikaʻi a me ka paʻa o ka lepo. I ka wā wili, hiki iā ia ke hoʻomaikaʻi i ka hiki ke lawe i ke one o ka lepo a hoʻolōʻihi i ke ola lawelawe o ka drill bit. Ma ka haʻahaʻa haʻahaʻa paʻa hoʻopiha wai a me ka cementing wai, ka maikaʻi o ka poho wai e hoʻemi ana i ka hana o ka hydroxyethyl cellulose hiki ke pale i ka nui o ka wai mai ke komo ʻana i ka ʻaila ʻaila mai ka lepo, a hiki ke hoʻomaikaʻi i ka mana hana o ka papa ʻaila.
Nā Kemika o kēlā me kēia lā
ʻO ka Hydroxyethyl cellulose kahi mea hana kiʻiʻoniʻoni maikaʻi, binder, thickener, stabilizer a me ka dispersant i nā shampoos, hair sprays, neutralizers, hair conditioners and cosmetics; i loko o ka pauda holoi He mea hoʻihoʻi lepo. Hoʻopau koke ka Hydroxyethyl cellulose i ka wela kiʻekiʻe, hiki ke wikiwiki i ke kaʻina hana a hoʻomaikaʻi i ka hana hana. ʻO ka hiʻohiʻona maopopo o ka mea holoi i loaʻa ka hydroxyethyl cellulose hiki ke hoʻomaikaʻi i ka maʻalahi a me ka siliki o ka lole.
hale hoʻolālā
Hiki ke hoʻohana ʻia ka Hydroxyethyl cellulose i nā huahana hana e like me ka hui ʻana o ke kaʻa, ka momi hou, ka plaster gypsum a i ʻole nā mea sima, a me nā mea ʻē aʻe, e mālama i ka wai i ka wā o ke kūkulu ʻana ma mua o ka hoʻonohonoho ʻana a paʻakikī. Ma kahi o ka hoʻomaikaʻi ʻana i ka paʻa wai o nā huahana kūkulu hale, hoʻolōʻihi ʻia ka hydroxyethyl cellulose i ka hoʻoponopono ʻana a me ka manawa wehe o ka plaster a i ʻole mastic. Hiki ke hōʻemi i ka ʻili, paheʻe a me ka luʻu. No laila, hiki ke hoʻomaikaʻi ʻia ka hana hana, hiki ke hoʻonui i ka hana hana, a hiki ke mālama ʻia ka manawa. I ka manawa like, hiki ke hoʻonui ʻia ka nui o ka hoʻonui ʻana o ka stucco, a laila e mālama ai i nā mea maka.
mahiʻai
Hoʻohana ʻia ʻo Hydroxyethyl cellulose i ka hoʻokumu ʻana i nā emulsions pesticide a me ka hoʻokuʻu ʻana, ma ke ʻano he mānoanoa no nā emulsions spray a i ʻole ka hoʻokuʻu. Hiki iā ia ke hōʻemi i ka neʻe ʻana o nā mea kemika a hoʻopaʻa paʻa i nā lau o nā mea kanu, a laila e hoʻonui ai i ka hopena o ka pulupulu lau. Hiki ke hoʻohana ʻia ka hydroxyethyl cellulose ma ke ʻano he mea hana kiʻiʻoniʻoni i loko o nā mea hoʻopili hua; ma ke ʻano he mea hoʻopaʻa a hana kiʻiʻoniʻoni i ka hana hou ʻana i nā lau paka.
Pepa a me ka Inika
Hiki ke hoʻohana ʻia ʻo Hydroxyethyl cellulose ma ke ʻano he ʻano nui no ka pepa a me ka papa a ma ke ʻano he mea mānoanoa a hoʻomaha no nā inika wai. I ke kaʻina hana pepa, ʻo nā waiwai maikaʻi o ka hydroxyethyl cellulose e pili pū me ka hapa nui o nā gums, resins a me nā paʻakai inorganic, haʻahaʻa haʻahaʻa, haʻahaʻa oxygen ʻai a me ka hiki ke hana i kahi kiʻiʻoniʻoni maʻemaʻe. ʻO ka kiʻiʻoniʻoni he haʻahaʻa haʻahaʻa ka permeability a me ka nani kiʻekiʻe, hiki ke hoʻemi i nā kumukūʻai. ʻO ka nui o ka pepa me ka hydroxyethyl cellulose, hiki ke hoʻohana ʻia no ka paʻi ʻana i nā kiʻi kiʻekiʻe. I ka hana ʻana i ka ʻīnika pili wai, maloʻo koke ka inika wai i hoʻopaʻa ʻia me ka hydroxyethyl cellulose, loaʻa ka diffusion kala maikaʻi, ʻaʻole ia e pili.
ka lole
Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa a hoʻopaʻa ʻia i ka paʻi lole a me ka hoʻoluʻu ʻana a me nā pena latex; ma ke ʻano he mānoanoa no ka hoʻonui ʻana i nā mea ma ke kua o nā moena. I loko o ke aniani fiber, hoʻohana ʻia ia ma ke ʻano he mea hana a me ka mea hoʻopili; i ka paʻi ʻili, hiki ke hoʻohana ʻia e like me ka hoʻololi a me ka mea hoʻopili. E hoʻolako i kahi laulā viscosity ākea no kēia mau uhi a i ʻole nā mea hoʻopili, e hoʻomaʻamaʻa i ka uhi a me ka wikiwiki, a hoʻomaikaʻi i ka maopopo o ka paʻi ʻana a me ke kala.
seramika
Hiki ke hoʻohana ʻia no ka hoʻokumu ʻana i nā mea hoʻopili ikaika kiʻekiʻe no nā seramika.
paʻu niho
Hiki ke hoʻohana ʻia ma ke ʻano he mānoanoa i ka hana ʻana i ka toothpaste.
