ʻO ka uhi anti-fog kahi ʻano uhi i loaʻa ka hana o ka pale ʻana i ka condensation noe.
Hoʻomaka ka loaʻa ʻana o nā hopena anti-fogging nā uhi super-hydrophilic me kahi kihi pili wai ma lalo o 15°.
Ke 4° ka huina pili wai, hōʻike ka uhi i ka hana anti-fog maikaʻi.
Ke ʻoi aku ka kiʻekiʻe o ka huina pili wai ma mua o 25 °, nalo loa ka hana anti-fog.
I ka makahiki 1970 (1967), ua ʻike ʻo Fujishima Akira, Hashimoto a me nā mea ʻē aʻe ma ke Kulanui o Tokyo i loaʻa i ka titanium dioxide (TiO2) nā waiwai hydrophilic a me ka hoʻomaʻemaʻe ponoʻī [1].Eia naʻe, inā ʻaʻole i hoʻomālamalama ʻia ka titanium dioxide me ke kukui ultraviolet, ʻo 72±1 ° ka huina pili wai.Ma hope o ka hoʻomālamalama ʻia ʻana o ke kukui ultraviolet, hoʻololi ke ʻano o ka titanium dioxide, a lilo ke kihi pili wai i 0±1 °.No laila, ua kaupalena ʻia e ke kukui ultraviolet ke hoʻohana ʻia [2].
Aia kekahi ala ʻē aʻe no ka pale ʻana i ka noe-sol-gel ala (sol-gel) [3] ʻōnaehana nano-silica (SiO2).Hoʻohui ʻia ka pūʻulu hydrophilic me ka framework nano-silica, a ʻo ka nano-silica framework a me ka organik-inorganic substrate hiki ke hana i kahi paʻa kemika ikaika.ʻO ka sol-gel anti-fog coating ka mea kū'ē i ka holoiʻana, ka hoʻouluʻana, a me nā mea hoʻoheheʻe.ʻOi aku ka lōʻihi ma mua o ka surfactant anti-fog coatings, ʻoi aku ka lahilahi ma mua o ka polymer anti-fog coatings, me ke kiʻekiʻe kiʻekiʻe, kiʻekiʻe ka uhi ʻana a ʻoi aku ka waiwai.
Ke hui ka mahu wai wela i ke anu, e lilo ia i papa o ka noe ma luna o ka ʻili o ka mea, kahi e pohihihi ai ka ʻike mua.Me ke kumu hydrophilic, Huzheng anti-fogging hydrophilic coating e hoʻomoe piha i ka wai no ka loaʻa ʻana o ke kiʻi wai like ʻole, ka mea e pale ai i ka hoʻokumu ʻana o ka hāʻule ʻana o ka noe, ʻaʻole pili i ka hoʻomaʻemaʻe ʻana o ka mea kumu, a mālama i ka ʻike maikaʻi.Huzheng coating hoʻolauna nanometer titanium oxide particles ma ke kumu o ka multicomponent polymerization, a me ka lōʻihi anti-fogging a me ka hoʻomaʻemaʻe pono hana.I ka manawa like, hoʻomaikaʻi maikaʻi ʻia ka paʻakikī a me ka pale ʻana o ka ʻili.ʻO PWR-PET ka hydrophilic anti-fogging coating no ka PET substrate, kahi kūpono no ka hoʻōla wela a kūpono hoʻi no ka uhi ʻana i ka ʻoihana nui.
ka palena:
Hiʻona:
-ʻO ka hana anti-fogging maikaʻi loa, ʻike maopopo me ka wai wela, ʻaʻohe wai e hāʻule ma ka ʻili;
- Loaʻa iā ia ka hana o ka hoʻomaʻemaʻe ponoʻī, hoʻokuke i ka lepo a me ka lepo mai ka ʻili me ka wai;
- ʻO ka hoʻopili maikaʻi ʻana, kūpaʻa i ka wai-boila, ʻaʻole hāʻule ka uhi, ʻaʻohe ʻōpū;
- Ke kū'ē ikaika i ka wā, ka hana hydrophilic anti-fogging no ka manawa lōʻihi, 3-5 mau makahiki.
Noi:
Hoʻohana ʻia ia no ka ʻili PET e hana i ka anti-fogging hydrophilic film a i ʻole pepa.
Hoʻohana:
E like me nā ʻano like ʻole, ka nui a me ke kūlana ʻili o ka mea kumu, koho ʻia nā ʻano noi kūpono, e like me ka ʻauʻau ʻauʻau, ka uhi ʻana a i ʻole ka uhi ʻana.Manaʻo ʻia e hoʻāʻo e uhi i kahi wahi liʻiliʻi ma mua o ka noi ʻana.E lawe i ka uhi ʻauʻau no ka laʻana e wehewehe pōkole i nā kaʻina noi penei:
Kaʻina 1: Ka uhi.E koho i ka ʻenehana uhi kūpono no ka uhi ʻana;
Kaʻanuʻu 2: Ma hope o ka uhi ʻana, kū i ka lumi wela no 3 mau minuke e hana i ka pae piha;
Kaʻina 3: ho'ōla.E hoʻokomo i ka umu, e wela i 80-120 ℃ no 5-30 mau minuke, a hoʻōla ka uhi.
