ʻO nā waiwai nui o ka hydroxyethyl cellulose he mea hiki ke hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela, ʻaʻohe waiwai gelling.Loaʻa iā ia kahi ākea o ka degere pani, solubility a me ka viscosity.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.
①Kiʻekiʻe ka wela a me ka wai hoʻoheheʻe: Hoʻohālikelike ʻia me ka methyl cellulose (MC), hiki ke hoʻoheheʻe ʻia i ka wai anuanu, hiki ke hoʻoheheʻe ʻia ka hydroxyethyl cellulose i ka wai wela a i ʻole ka wai anuanu.Ka laulā o ka solubility a me ka viscosity waiwai, a me ka non-thermal gelation.
②Paʻakai pale: Ma muli o kona ʻano non-ionic, hiki iā ia ke hui pū me nā polymers hiki ke hoʻoheheʻe ʻia i ka wai, surfactants a me nā paʻakai ma kahi ākea.No laila, ke hoʻohālikelike ʻia me ka ionic carboxymethyl cellulose (CMC), ʻoi aku ka maikaʻi o ka paʻakai hydroxyethyl cellulose.
③Ka paʻa wai, pae, hana kiʻiʻoniʻoni: ʻelua ka nui o ka mālama ʻana i ka wai ma mua o ka methyl cellulose, me ka hoʻoponopono maikaʻi ʻana a me ka hana kiʻiʻoniʻoni maikaʻi loa, ka emi ʻana o ka wai, miscibility, pale colloid sex.
Hoʻohana i ka hydroxyethyl cellulose
ʻO ka Hydroxyethyl cellulose kahi huahana cellulose ether non-ionic wai, hoʻohana nui ʻia i nā hale kūkulu hale, petroleum, polymer polymerization, lāʻau lapaʻau, hoʻohana i kēlā me kēia lā, pepa a me ka inika, nā 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 ka 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.ʻO kekahi o ka cellulose ethers wikiwiki.
1 pena latex
ʻO ka Hydroxyethyl cellulose ka mānoanoa maʻamau i hoʻohana ʻia i nā uhi latex.Ma waho aʻe o ka mānoanoa o ka latex coatings, hiki iā ia ke emulsify, hoʻopuehu, hoʻopaʻa a mālama i ka wai.Hōʻike ʻia ia e ka hopena mānoanoa kupaianaha, hoʻomohala kala maikaʻi, waiwai 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 hana e like me ka palaki ʻana, ka uhi ʻana i ka wili, a me ka pipi ʻana.Maikaʻi ke kūkulu ʻana, ʻaʻole maʻalahi e kulu, sag a splash, a me ka pae maikaʻi.
2 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, "kiʻiʻoniʻoni" lahilahi o nā ʻāpana, ka nui o ka nui o nā ʻāpana, ke ʻano o nā ʻāpana like ʻole, ke ʻano ʻokoʻa, ka wai maikaʻi, ka ʻike kiʻekiʻe o ka huahana 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 gelling, ʻoi aku ka maikaʻi no nā ʻano like ʻole polymerization.
ʻO nā waiwai kino koʻikoʻi no ka noiʻi ʻana i ka maikaʻi o ka mea hoʻopuehu 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 hoʻohālikelike maikaʻi me nā eter cellulose hiki ke hoʻoheheʻe wai a me PVA.Hiki i ka ʻōnaehana hoʻohuihui i hana ʻia pēlā ke loaʻa ka hopena piha o ke aʻo ʻana mai nā ikaika o kekahi a me ka hoʻokō ʻana i nā nāwaliwali o kekahi.ʻAʻole maikaʻi wale ka maikaʻi o nā huahana resin composite, akā e hōʻemi hoʻi i ka poho waiwai.
3 wili aila
I ka ʻaila ʻaila a me ka hana ʻana, hoʻohana nui ʻia ka hydroxyethyl cellulose kiʻekiʻe ma ke ʻano he viscosifier no ka hoʻopiha wai a me ka hoʻopau ʻana i ka wai.Hoʻohana ʻia ka hydroxyethyl cellulose haʻahaʻa haʻahaʻa ma ke ʻano he mea hoʻemi hoʻemi wai.I loko o nā ʻōpala like ʻole i koi ʻia no ka ʻeli ʻana, hoʻopau, cementing a me nā hana haki, 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 o ka wili ʻana, 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 paʻa hoʻopiha wai a me ka cementing wai, ka maikaʻi wai poho ho'ēmi waiwai o hydroxyethyl cellulose hiki ke pale aku i ka nui o ka wai mai ke komo ana i ka aila papa mai ka lepo, a hiki ke hoʻomaikaʻi i ka hana o ka aila papa.
4 Kemika i kēlā me kēia lā
ʻO Hydroxyethylcellulose kahi kiʻiʻoniʻoni maikaʻi mua, binder, thickener, stabilizer a me ka dispersant i nā shampoos, nā lauoho lauoho, neutralizers, conditioners a me nā mea hoʻonaninani;i loko o nā pauka hoʻomaʻemaʻe He mea hoʻoponopono hou i ka lepo.Hoʻopau koke ka Hydroxyethyl cellulose i ka wela kiʻekiʻe, hiki ke wikiwiki i ka hana hana a hoʻomaikaʻi i ka hana hana.ʻO ka hiʻohiʻona maopopo o nā mea holoi i loaʻa ka hydroxyethyl cellulose hiki iā ia ke hoʻomaikaʻi i ka maʻalahi a me ka mercerization o nā lole.
5 hale hana
Hiki ke hoʻohana ʻia ʻo Hydroxyethyl cellulose i nā huahana kūkulu e like me nā hui ʻana o ke kaʻa, nā morta hou, ka plaster gypsum a i ʻole nā morta ʻē aʻe, a me nā mea ʻē aʻe, e mālama i ka wai i ke kūkulu ʻana ma mua o ka hoʻonohonoho ʻana a paʻakikī.Ma waho aʻe o ka hoʻomaikaʻi ʻana i ka mālama ʻana i ka wai o nā huahana kūkulu hale, hiki i ka hydroxyethyl cellulose ke hoʻolōʻihi i ka hoʻoponopono a me ka manawa wehe o ka stucco a i ʻole ka mastic.Hoʻemi i ka ʻili, paheʻe a me ka luʻu.Hiki i kēia ke hoʻomaikaʻi i ka hana hana, hoʻomaikaʻi i ka hana pono, mālama i ka manawa, a ma ka manawa like e hoʻonui i ka nui o ka hoʻonui ʻana o ka stucco, a laila e mālama ai i nā mea maka.
6 mahiai
Hoʻohana ʻia ʻo Hydroxyethyl cellulose i loko o ka pesticide emulsion a me ka hoʻopiʻi ʻana e like me ka mānoanoa no nā emulsions spray a i ʻole nā suspensions.Hiki iā ia ke hōʻemi i ka neʻe ʻana o ka mea hana a hoʻopaʻa paʻa i ka lau o ka mea kanu, a laila e hoʻonui ai i ka hopena o ka hoʻoulu ʻana o ka foliar.Hiki ke hoʻohanaʻia ka Hydroxyethyl cellulose ma keʻano he mea hana kiʻiʻoniʻoni i ka hoʻopiliʻana i nā hua a me ka mea hoʻopili;ma ke ʻano he mea hoʻopaʻa a hana kiʻiʻoniʻoni i ka hana hou ʻana i nā lau paka.
7 Pepa a me ka Inika
Hiki ke hoʻohana ʻia ʻo Hydroxyethyl cellulose ma ke ʻano he mea nui ma 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 haʻahaʻa oxygen a me ka hiki ke hana i kahi kiʻiʻoniʻoni maʻemaʻe.ʻO ka kiʻiʻoniʻoni he haʻahaʻa haʻahaʻa ka permeability a me ka ikaika o ka nani, a hiki ke hoʻemi i nā kumukūʻai.Nui ka pepa me ka hydroxyethyl cellulose no nā paʻi kiʻekiʻe.I ka hana ʻana i ka ʻīnika ma ka wai, maloʻo koke ka inika wai i hoʻopaʻa ʻia me ka hydroxyethyl cellulose, loaʻa ka diffusion kala maikaʻi, ʻaʻole hoʻi e hoʻopili.
8 lole
Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa a me ka nui ʻana i ka paʻi lole a me ka paʻi kala a me ka pena latex;mea mānoanoa no ka nui ʻana o nā mea ma ke kua o ke kāpeti.I loko o ke aniani fiber, hoʻohana ʻia e like me ka mea hoʻoheheʻe a me ka mea hoʻopili;i ka pulp ʻili, hiki ke hoʻohana ʻia e like me ka hoʻololi a me ka mea hoʻopili.Hāʻawi i kahi laulā viscosity ākea no kēia mau uhi a i ʻole nā mea hoʻopili, e hopena i kahi ʻano like a me ka hoʻoponopono wikiwiki ʻana o ka uhi a hoʻomaikaʻi ʻia ka paʻi ʻana.
9 seramika
Mea hoʻopili ikaika kiʻekiʻe no ka hoʻokumu ʻana i nā seramika.
10 toothpaste
Hiki ke hoʻohana ʻia ma ke ʻano he mānoanoa i ka hana ʻana i ka toothpaste.
