ʻO nā waiwai nui o ka hydroxyethyl cellulose, he mea hiki ke hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela, a ʻaʻohe ona waiwai gelling. Loaʻa iā ia kahi ākea o ke kekelē pani, ka solubility a me ka viscosity. Ua hoʻoheheʻe ʻia. Hiki i ka hopena Hydroxyethyl cellulose ke hana i kahi ʻili aniani, a he mau ʻano ʻano non-ionic ʻaʻole e launa pū me nā ions a he kūpono maikaʻi.
①Ka mahana kiʻekiʻe a me ka wai hoʻoheheʻe ʻia: Ke hoʻohālikelike ʻia me ka methyl cellulose (MC), ka mea hiki ke hoʻoheheʻe wale ʻia i ka wai anuanu, hiki ke hoʻoheheʻe ʻia ka hydroxyethyl cellulose i ka wai wela a i ʻole ka wai anuanu. ʻO ka laulā o nā waiwai solubility a me ka viscosity, a me ka gelation non-thermal.
②Ke kū'ē pa'akai: Ma muli o kona ʻano non-ionic, hiki ke noho pū me nā polymers wai-soluble ʻē aʻe, nā surfactants a me nā paʻakai ma kahi ākea. No laila, i hoʻohālikelike ʻia me ka ionic carboxymethyl cellulose (CMC), ʻoi aku ka maikaʻi o ke kū'ē pa'akai o ka hydroxyethyl cellulose.
③Paʻa wai, hoʻohālikelike, hana ʻoniʻoni: ʻo kona hiki ke mālama wai he ʻelua o ka methyl cellulose, me ka hoʻoponopono kahe maikaʻi loa a me ka hana ʻoniʻoni maikaʻi loa, hoʻemi i ka nalowale o ke kahe, miscibility, pale colloid sex.
Ka hoʻohana ʻana i ka hydroxyethyl cellulose
ʻO ka Hydroxyethyl cellulose kahi huahana cellulose ether wai-soluble non-ionic, i hoʻohana nui ʻia i nā uhi hale, petroleum, polymer polymerization, lāʻau lapaʻau, hoʻohana i kēlā me kēia lā, pepa a me ka ʻīnika, nā lole, nā keramika, ke kūkulu ʻana, ka mahiʻai a me nā ʻoihana ʻē aʻe. Loaʻa iā ia nā hana o ka hoʻomānoanoa, ka hoʻopaʻa ʻana, ka emulsifying, ka hoʻopuehu ʻana a me ka hoʻopaʻa ʻana, a hiki ke hoʻopaʻa i ka wai, hana i kahi kiʻiʻoniʻoni a hāʻawi i ka hopena colloid pale. He maʻalahi ka hoʻoheheʻe ʻia i ka wai anuanu a me ka wai wela, a hiki ke hāʻawi i kahi hopena me kahi ākea o ka viscosity. ʻO kekahi o nā ethers cellulose wikiwiki.
1 pena latex
ʻO ka Hydroxyethyl cellulose ka mea hoʻomānoanoa i hoʻohana nui ʻia i nā uhi latex. Ma waho aʻe o ka hoʻomānoanoa ʻana i nā uhi latex, hiki iā ia ke hoʻoheheʻe, hoʻopuehu, hoʻopaʻa a mālama i ka wai. Hōʻike ʻia ia e ka hopena mānoanoa kupaianaha, ka hoʻomohala kala maikaʻi, ka waiwai hana kiʻiʻoniʻoni a me ke kūpaʻa mālama. ʻO ka Hydroxyethyl cellulose kahi derivative cellulose non-ionic hiki ke hoʻohana ʻia ma kahi ākea pH. Loaʻa iā ia ka hoʻohālikelike maikaʻi me nā mea ʻē aʻe i loko o ka ʻāpana (e like me nā pigments, nā mea hoʻohui, nā mea hoʻopiha a me nā paʻakai). ʻO nā uhi i hoʻomānoanoa ʻia me ka hydroxyethyl cellulose he rheology maikaʻi ma nā ʻano shear like ʻole a he pseudoplastic. Hiki ke hoʻohana ʻia nā ʻano hana kūkulu e like me ka palaki ʻana, ka uhi ʻana i ka wili, a me ka pīpī ʻana. Hana maikaʻi, ʻaʻole maʻalahi ke kahe, sag a splash, a me ka pae maikaʻi.
2 Hoʻohuihui
Loaʻa i ka Hydroxyethyl cellulose nā hana o ka hoʻopuehu ʻana, ka emulsifying, ke kau ʻana a me ka hoʻopaʻa ʻana i nā ʻāpana polymerization a i ʻole copolymerization o nā resins synthetic, a hiki ke hoʻohana ʻia ma ke ʻano he colloid pale. Hōʻike ʻia ia e ka hiki ke hoʻopuehu ikaika, ka "ʻili lahilahi" o nā ʻāpana, ka nui o nā ʻāpana maikaʻi, ke ʻano like o nā ʻāpana, ke ʻano wehe, ka wai maikaʻi, ka transparency huahana 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 ona wahi mahana gelling, ʻoi aku ka kūpono no nā ʻano hana polymerization like ʻole.
ʻO nā waiwai kino koʻikoʻi e noiʻi ai i ka maikaʻi o ka mea hoʻolaha, ʻo ia ka ʻili (a i ʻole ka interfacial) tension, ka ikaika interfacial a me ka mahana gelation o kāna hopena wai. He kūpono kēia mau waiwai o ka hydroxyethyl cellulose no ka polymerization a i ʻole copolymerization o nā resins synthetic.
He kūpono ka Hydroxyethyl cellulose me nā ethers cellulose wai-soluble ʻē aʻe a me PVA. Hiki i ka ʻōnaehana composite i hoʻokumu ʻia ke loaʻa ka hopena piha o ke aʻo ʻana mai nā ikaika o kekahi a me ka hoʻopiha ʻana i nā nāwaliwali o kekahi. ʻAʻole wale ka maikaʻi o nā huahana resin composite, akā hoʻemi pū kekahi i ka nalowale o nā mea.
3 ʻeli ʻaila
I ka ʻeli ʻana a me ka hana ʻana o ka ʻaila, hoʻohana nui ʻia ka hydroxyethyl cellulose kiʻekiʻe-viscosity ma ke ʻano he viscosifier no nā wai hoʻopau a me nā wai hoʻopau. Hoʻohana ʻia ka hydroxyethyl cellulose haʻahaʻa viscosity ma ke ʻano he mea hōʻemi i ka pohō wai. I nā ʻano lepo like ʻole e pono ai no ka ʻeli ʻana, hoʻopau ʻana, hana sima a me ka haki ʻana, hoʻohana ʻia ka hydroxyethyl cellulose ma ke ʻano he mea hoʻomānoanoa e loaʻa ai ka wai maikaʻi a me ke kūpaʻa o ka lepo. I ka wā o ka ʻeli 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 ʻāpana wili. I nā wai hoʻopau pae paʻa haʻahaʻa a me nā wai sima, ʻo nā waiwai hōʻemi wai maikaʻi loa o ka hydroxyethyl cellulose hiki ke pale i ka nui o ka wai mai ke komo ʻana i ka papa aila mai ka lepo, a hiki ke hoʻomaikaʻi i ka hiki ke hana o ka papa aila.

He mea hana kiʻiʻoniʻoni maikaʻi ʻo Hydroxyethylcellulose, mea hoʻopaʻa, mea hoʻomānoanoa, mea hoʻopaʻa a me ka mea hoʻolaha i nā shampoos, nā ʻūlū lauoho, nā mea hoʻohaʻahaʻa, nā mea hoʻomaʻemaʻe a me nā mea hoʻonani; i loko o nā pauka detergent He mea hoʻihoʻi lepo ia. Hoʻoheheʻe koke ʻo Hydroxyethyl cellulose i ka mahana kiʻekiʻe, hiki ke hoʻolalelale i ke kaʻina hana a hoʻomaikaʻi i ka pono hana. ʻO ka hiʻohiʻona maopopo o nā detergents e loaʻa ana ka hydroxyethyl cellulose ʻo ia ka hiki ke hoʻomaikaʻi i ka maʻalahi a me ka mercerization o nā lole.
5 kuhikuhipuʻuone
Hiki ke hoʻohana ʻia ka Hydroxyethyl cellulose i nā huahana kūkulu hale e like me nā hui sima, nā mortars hou, ka plaster gypsum a i ʻole nā mortars ʻē aʻe, a pēlā aku, e mālama i ka wai i ka wā o ke kūkulu ʻana ma mua o ko lākou hoʻopaʻa ʻana a me ka paʻakikī. Ma waho aʻe o ka hoʻomaikaʻi ʻana i ka paʻa ʻana o 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 mastic. Hoʻemi i ka ʻili ʻana, ka paheʻe ʻana a me ka sagging. Hiki i kēia ke hoʻomaikaʻi i ka hana kūkulu hale, hoʻomaikaʻi i ka pono o ka hana, mālama i ka manawa, a i ka manawa like e hoʻonui ai i ka nui o ka hoʻonui ʻana o ka stucco, a laila mālama i nā mea maka.

Hoʻohana ʻia ka Hydroxyethyl cellulose i loko o nā pesticide emulsion a me nā ʻano hoʻoheheʻe ʻia ma ke ʻano he mea hoʻomānoanoa no nā emulsions pīpī a i ʻole nā hoʻoheheʻe ʻia. Hiki iā ia ke hōʻemi i ka hele ʻana o ka mea hana a hoʻopaʻa pono iā ia i nā lau o ka mea kanu, a laila e hoʻonui ai i ka hopena o ka pīpī foliar. Hiki ke hoʻohana ʻia ka Hydroxyethyl cellulose ma ke ʻano he mea hana kiʻiʻoniʻoni i ka uhi ʻana i nā hua a me nā mea uhi; ma ke ʻano he mea hoʻopaʻa a me ka mea hana kiʻiʻoniʻoni i ka hana hou ʻana o nā lau paka.
7 Pepa a me ka ʻīnika
Hiki ke hoʻohana ʻia ka Hydroxyethyl cellulose ma ke ʻano he mea hoʻonui i ka nui ma ka pepa a me ka papa a ma ke ʻano he mea hoʻomānoanoa a hoʻokuʻu no nā ʻīnika wai. I ke kaʻina hana pepa, ʻo nā waiwai maikaʻi loa o ka hydroxyethyl cellulose e pili ana i ka hoʻohālikelike ʻana me ka hapa nui o nā gums, resins a me nā paʻakai inorganic, ka hua haʻahaʻa, ka hoʻohana ʻana i ka oxygen haʻahaʻa a me ka hiki ke hana i kahi kiʻiʻoniʻoni ʻili laumania. ʻOi aku ka haʻahaʻa o ka permeability o ka ʻili a me ka ʻōlinolino ikaika, a hiki ke hōʻemi i nā kumukūʻai. Hoʻonui ʻia ka pepa me ka hydroxyethyl cellulose no nā paʻi kiʻekiʻe. I ka hana ʻana i ka ʻīnika wai, maloʻo koke ka ʻīnika wai i hoʻomānoanoa ʻia me ka hydroxyethyl cellulose, maikaʻi ka hoʻolaha kala, a ʻaʻole ia e hoʻopili.
8 lole
Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻopaʻa a me ka mea hoʻonui i ka nui i ka paʻi lole a me ka hoʻoluʻu ʻana i ka pepa a me ka pena latex; mea hoʻomānoanoa no ka mea hoʻonui i ka nui ma ke kua o ke kāpeti. I loko o ke olonā aniani, hoʻohana ʻia ia ma ke ʻano he mea hoʻoheheʻe a me ka mea hoʻopaʻa; i loko o ka pulp ʻili, hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻololi a me ka mea hoʻopaʻa. Hāʻawi i kahi laulā ākea o ka viscosity no kēia mau uhi a i ʻole nā mea hoʻopili, e hopena ana i kahi noho like a wikiwiki o ka uhi a hoʻomaikaʻi i ka maopopo o ka paʻi.
