Ko te paninga anti kohu mo te kiriata PET

Ko te paninga anti-fog he momo paninga e whai ana i te mahi o te aukati i te kohu condensation.
Ko nga paninga super-hydrophilic me te koki whakapiri wai o te iti iho i te 15° ka timata ki te whai hua anti-fogging.
Ina he 4° te koki whakapiri wai, ka whakaatu te paninga he pai te mahi anti-kohu.
Ina teitei ake te koki whakapiri wai i te 25°, ka ngaro katoa te mahi anti-kohu.
I te tekau tau atu i 1970 (1967), i kitea e Fujishima Akira, Hashimoto me etahi atu o te Whare Wananga o Tokyo ko te titanium dioxide (TiO2) he waiariki me te horoi whaiaro [1].Heoi, ki te kore te titanium dioxide e whakahiahia ki te rama ultraviolet, ko te koki whakapiri wai ko te 72±1°.I muri i te whakamaaramatanga o te rama ultraviolet, ka huri te hanganga o te titanium dioxide, ka 0±1° te koki whakapiri wai.Na reira, ka whakawhäitihia e te rama ultraviolet ka whakamahia [2].
He huarahi ano mo te whakakikorua i te kohu-sol-gel tikanga (sol-gel) [3] punaha o te nano-silica (SiO2).Ka honoa te roopu hydrophilic me te anga nano-silica, a ka taea e te anga nano-silica me te substrate organic-inorganic te hanga i tetahi hononga matū kaha.Ko te paninga anti-kohu sol-gel he atete ki te horoi, te hukahuka, me te whakarewa.He roa ake i nga paninga anti-kohu surfactant, he angiangi ake i nga paninga anti-kohu polymer, me te tino tika, te reeti paninga teitei me te ohanga.

Ina tutaki te kohu wai wera ki te makariri, ka hanga he paparanga kohu wai ki runga i te mata o te mea, ka purua te tirohanga tuatahi.Ma te kaupapa hydrophilic, Huzheng anti-fogging paninga hydrophilic hanga nga pata wai tino whakatakotoria ki te tiki kiriata wai kākahu, e ārai i te hanganga o te kohu maturuturunga iho, e kore e pā te whakawāteatanga o te rauemi turanga, me te pupuri i te tikanga ataata pai.Huzheng paninga whakauru nanometer titanium waikura matūriki i runga i te kaupapa o te polymerization multicomponent, a ka whiwhi mahi anti-fogging me te horoi-whaiaro.I te wa ano, ka tino pai ake te pakeke me te mau atete o te mata.Ko te PWR-PET te paninga anti-fogging hydrophilic mo te taputapu PET, he pai mo te tukanga whakamahana wera me te watea mo te paninga ahumahi nui.

Tawhā:

Āhuahira:

- He pai te mahi anti-fogging, he maamaa te tirohanga me te wai wera, kaore he wai e heke ki te mata;
-Kei a ia te mahi o te horoi whaiaro, te taraiwa i te paru me te puehu i te mata me te wai;
-He pai te piri, te wai-kopu atete, te paninga e kore e taka, kahore he mirumiru;
-He kaha te aukati huarere, he roa te mahi hydrophilic anti-fogging, 3-5 tau.

Taupānga:

Ka whakamahia mo te mata PET ki te whakaputa i te kiriata hydrophilic anti-fogging pepa ranei.

Whakamahinga:

E ai ki te ahua rereke, te rahi me te ahua o te mata o te papanga turanga, ko nga tikanga tono e tika ana, penei i te paninga ua, te paninga horoi, te paninga rehu ranei ka tohua.E taunaki ana kia whakamatauhia te paninga ki tetahi waahi iti i mua i te tono.Tangohia te paninga kaukau hei tauira ki te whakaahua i nga waahanga tono penei e whai ake nei:

Hipanga 1: Whakakikorua.Tīpakohia te hangarau whakakikorua e tika ana mo te paninga;
Hipanga 2: I muri i te paninga, tu i te pāmahana rūma mo te 3 meneti kia tino whakataurite;
Hipanga 3: te rongoa.Whakauruhia te oumu, whakamahana i te 80-120 ℃ mo te 5-30 meneti, ka ora te paninga.

 

Tuhipoka:
1.Kia mau te hiri me te penapena ki te waahi hauhautanga, kia marama te tapanga kia kore ai e whakamahi kino.

2. Kia matara atu i te ahi, ki te wahi e kore e taea e nga tamariki;

3. Kia pai te hau me te aukati i te ahi;

4. Mau PPE, penei i nga kakahu whakamarumaru, nga karapu tiaki me nga moti;

5. Kaua e pa atu ki te waha, ki nga kanohi me te kiri, mena ka pa atu, horoia ki te wai nui tonu, waea atu ki te taote mena e tika ana.

Tapeke:

Taapiri: 20 rita / oko;
Rokiroki: i roto i te wahi raumati, maroke, karo i te ra.
