1. He aha ka hydroxyethyl cellulose (HEC)?
Hydroxyethyl cellulose (HEC)he hui polimer maoli a me ka derivative cellulose. He pūhui etera hiki ke hoʻoheheʻe ʻia i ka wai i loaʻa ma ka hopena o ka cellulose me ka ethylene oxide. Aia i loko o ke kinona o ka hydroxyethyl cellulose ka iwi o ka cellulose, a ma ka manawa like e hoʻokomo i nā mea pani hydroxyethyl (-CH2CH2OH) i loko o kāna kaulahao mole, e hāʻawi iā ia i ka solubility i ka wai a me kekahi mau waiwai kino a me kemika. He mea ʻawaʻawa ʻole, ʻaʻole hoʻonāukiuki a biodegradable kemika i hoʻohana nui ʻia i nā ʻoihana like ʻole.
2. Ka hana o ka hydroxyethyl cellulose
Hiki ke hoʻoheheʻe wai: Hydroxyethyl cellulose hiki ke hoʻoheheʻe ʻia i loko o ka wai a hiki ke hoʻoheheʻe koke ʻia i loko o ka wai anuanu a i ʻole ka wai wela e hana i kahi hopena viscous. Hoʻonui ka solubility me ka piʻi ʻana o ke kiʻekiʻe o ka hydroxyethylation, no laila he mana maikaʻi ia i nā noi ʻoihana.
Nā hiʻohiʻona viscosity: ʻO ka viscosity solution o ka hydroxyethyl cellulose e pili kokoke ana i kona kaumaha mole, ke degere o ka hydroxyethylation a me ka neʻe ʻana o ka hopena. Hiki ke hoʻololi ʻia kona viscosity i nā noi like ʻole e hoʻokō i nā koi kaʻina hana like ʻole. Ma nā haʻahaʻa haʻahaʻa, hana ia ma ke ʻano he haʻahaʻa haʻahaʻa haʻahaʻa, ʻoiai ma nā kiʻekiʻe kiʻekiʻe, piʻi wikiwiki ka viscosity, e hāʻawi ana i nā waiwai rheological ikaika.
Nonionicity: ʻO ka hydroxyethyl cellulose kahi mea hoʻoheheʻe nonionic ʻaʻole i hoʻopilikia ʻia e nā loli i ka waiwai pH o ka hopena, no laila ke hōʻike nei ia i ke kūpaʻa maikaʻi ma lalo o nā kūlana kaiapuni like ʻole. Hoʻohana nui ʻia kēia waiwai i nā formulations he nui e pono ai ke kūpaʻa.
Mānoanoa: ʻO ka hydroxyethyl cellulose nā waiwai mānoanoa maikaʻi a hoʻohana ʻia ma ke ʻano he mānoanoa i nā ʻano wai wai. Hiki iā ia ke hoʻonui i ka viscosity o ka wai a hoʻoponopono i ka wai a me ka hana o ka huahana.
Nā waiwai hana kiʻiʻoniʻoni a emulsifying: ʻO ka Hydroxyethyl cellulose kekahi mau waiwai hana kiʻiʻoniʻoni a emulsifying, a hiki ke hoʻopuehu paʻa i nā mea like ʻole i loko o kahi ʻōnaehana multiphase. He mea koʻikoʻi kēia waiwai i ka ʻoihana hoʻonaninani a me nā ʻoihana uhi.
Paʻa wela a me ka solubility:Hydroxyethyl celluloseʻano paʻa i ka wela, hiki ke mālama i kona solubility a me kāna hana i loko o kahi pae wela, a hoʻololi i nā pono o nā wahi wela kiʻekiʻe. Hoʻohana maikaʻi kēia waiwai no ka hoʻohana ʻana i kekahi mau kaiapuni kūikawā.
Biodegradability: Ma muli o kona kumu cellulose maoli, hydroxyethyl cellulose he biodegradability maikaʻi, no laila he liʻiliʻi ka hopena i ke kaiapuni a he mea pili i ke kaiapuni.
3. Nā kahua noi o ka hydroxyethyl cellulose
ʻOihana hana a me ka uhi ʻana: Hoʻohana pinepine ʻia ʻo Hydroxyethyl cellulose ma ke ʻano he mānoanoa a me ka mea mālama wai i ka ʻoihana kūkulu, a hoʻohana nui ʻia i ka mortar sima, nā mea hoʻopili, ka mortar maloʻo a me nā huahana ʻē aʻe. Hiki iā ia ke hoʻomaikaʻi i ka operability a me ka fluidity o ka mea, hoʻomaikaʻi i ka adhesion a me ka hana wai ʻole o ka uhi. Ma muli o kona paʻa wai maikaʻi, hiki iā ia ke hoʻolōʻihi i ka manawa wehe o ka mea, pale i ka evaporation o ka wai me ka wikiwiki, a hōʻoia i ka maikaʻi o ke kūkulu ʻana.
ʻO ka ʻaila ʻaila a me ka wai hoʻoheheʻe: I ka ʻaila ʻaila, hoʻohana ʻia ka hydroxyethyl cellulose ma ke ʻano he mānoanoa no ka hoʻoheheʻe ʻana i ka wai a me ka wai hoʻopau, hiki ke hoʻoponopono pono i ka rheology o ka wai, pale i ka waiho ʻana o ka lepo ma ka pā luawai a hoʻopaʻa i ka hoʻolālā o ka pā punawai. Hiki iā ia ke hōʻemi i ke komo ʻana o ka wai a hoʻomaikaʻi i ka pono a me ka palekana o ka wili.
ʻoihana hoʻonaninani:Hydroxyethyl cellulosehoʻohana nui ʻia i nā huahana mālama ʻili, shampoo, gel wai, ʻili maka a me nā huahana ʻē aʻe e like me ka mānoanoa, emulsifier a me ka stabilizer i nā mea hoʻonaninani. Hiki iā ia ke hoʻonui i ka viscosity o ka huahana, hoʻomaikaʻi i ka wai o ka huahana, hoʻonui i ka manaʻo o ka huahana, a hana pū i kahi kiʻi pale ma ka ʻili e kōkua i ka moisturize a pale.
ʻOihana Lapaʻau: Hoʻohana ʻia ʻo Hydroxyethyl cellulose ma ke ʻano he mea hoʻopaʻa lāʻau lapaʻau, hoʻokuʻu i hoʻopaʻa ʻia, a me ka mea hoʻopiha no nā papa a me nā capsules i ka ʻoihana lāʻau. Hiki iā ia ke hoʻomaikaʻi i nā waiwai kino o ka hoʻomākaukau ʻana i ka lāʻau a hoʻonui i ka paʻa a me ka bioavailability o nā lāʻau lapaʻau.
ʻOihana lole a me ka hana pepa: I loko o ka ʻoihana lole, hiki ke hoʻohana ʻia ka hydroxyethyl cellulose ma ke ʻano he mea hoʻonaninani a me ka paʻi paʻi ʻana e hoʻomaikaʻi i ka like ʻole o ke kala a me ka palupalu o nā lole. I ka ʻoihana hana pepa, hoʻohana ʻia ia ma ke ʻano he mānoanoa i nā uhi pepa e hoʻomaikaʻi i ka maikaʻi o ka paʻi ʻana a me ka nani o ka pepa.
ʻOihana Meaʻai: Hoʻohana pū ʻia ʻo Hydroxyethyl cellulose i ka hoʻoili ʻana i ka meaʻai, ma ke ʻano he mānoanoa, emulsifier a me stabilizer. Hiki iā ia ke hoʻololi i ka ʻono a me ke ʻano o ka meaʻai, no ka laʻana, i ka ice cream, jelly a me nā mea inu, hiki ke hoʻomaikaʻi i ka paʻa a me ka palatability o ka huahana.
Mahiʻai: Ma ka māla mahiʻai, hoʻohana pinepine ʻia ka hydroxyethyl cellulose i ka hoʻomākaukau ʻana i nā pesticide, nā mea hoʻonaninani a me nā huahana pale mea kanu. ʻO kona mānoanoa a me ka moisturizing waiwai e kōkua i ka hoʻomaikaʻi ʻana i ka kūlike a me ka hoʻopili ʻana o nā mea hoʻoheheʻe ʻana, a laila e hoʻomaikaʻi ai i ka maikaʻi o nā pesticides a hōʻemi i ka pollution i ke kaiapuni.
Nā kemika o kēlā me kēia lā: I ka hoʻomaʻemaʻe hale a me nā huahana mālama pilikino, hoʻohana ʻia ka hydroxyethyl cellulose ma ke ʻano he mānoanoa a me ka stabilizer e hoʻonui ai i ka hopena hoʻohana a me ka manaʻo o ka huahana. No ka laʻana, hoʻohana pinepine ʻia i nā kemika o kēlā me kēia lā e like me ka wai holoi kīʻaha, nā mea holoi lole, a me nā mea hoʻomaʻemaʻe maka.
Hydroxyethyl cellulosehe hui mole kiʻekiʻe me ka hana ʻoi aku ka maikaʻi a me ka nui o nā hoʻohana. ʻO kona hoʻoheheʻe wai maikaʻi, mānoanoa, kūpaʻa wela a me ka biodegradability e hoʻohana nui ʻia i nā kula he nui e like me ke kūkulu ʻana, ka ʻaila, nā mea hoʻonaninani, nā lāʻau lapaʻau, a me nā textiles. Me ka hoʻomaikaʻi ʻana i nā koi palekana kaiapuni a me nā holomua ʻenehana, e ʻoi aku ka laulā o nā noi noi o HEC a lilo i koho koʻikoʻi no nā mea palekana kaiapuni a me nā mea hoʻohui hana.
