Kupaka kwa anti-fog ndi mtundu wa zokutira zomwe zimakhala ndi ntchito yoletsa kukhazikika kwa chifunga.
Zovala za super-hydrophilic zokhala ndi ngodya yolumikizana ndi madzi zosakwana 15 ° zimayamba kukhala ndi zotsutsana ndi chifunga.
Pamene ngodya yolumikizana ndi madzi ndi 4 °, zokutira zimasonyeza ntchito yabwino yolimbana ndi chifunga.
Pamene ngodya yokhudzana ndi madzi ndi yoposa 25 °, ntchito yotsutsa chifunga imasowa kwathunthu.
Mu 1970s (1967), Fujishima Akira, Hashimoto ndi ena pa yunivesite ya Tokyo anapeza kuti titanium dioxide (TiO2) ali ndi hydrophilic ndi kudziyeretsa katundu [1].Komabe, titanium dioxide ikapanda kuyatsa ndi kuwala kwa ultraviolet, mbali yolumikizana ndi madzi ndi 72±1°.Pambuyo pa kuyatsa kwa ultraviolet, mapangidwe a titaniyamu woipa amasintha, ndipo madzi okhudzana ndi madzi amakhala 0 ± 1 °.Chifukwa chake, imachepetsedwa ndi kuwala kwa ultraviolet ikagwiritsidwa ntchito [2].
Palinso njira ina ya anti-fog zokutira-sol-gel njira (sol-gel) [3] dongosolo la nano-silica (SiO2).Gulu la hydrophilic limaphatikizidwa ndi chimango cha nano-silica, ndipo mawonekedwe onse a nano-silica ndi gawo la organic-inorganic akhoza kupanga mgwirizano wamphamvu wamankhwala.Chophimba cha sol-gel anti-fog sichimva kukanda, kuchita thovu, ndi zosungunulira.Ndiwolimba kuposa zokutira zothana ndi chifunga, zowonda kwambiri kuposa zokutira za polima zothana ndi chifunga, zolondola kwambiri, zokutira zazitali komanso zotsika mtengo.

Pamene nthunzi wamadzi otentha ukumana ndi kuzizira, umapanga chifunga chamadzi pamwamba pa chinthucho, chomwe chimapangitsa kuti mawonekedwe oyambirirawo asawoneke bwino.Ndi mfundo ya hydrophilic, Huzheng anti-fogging hydrophilic ❖ kuyanika kumapangitsa kuti madontho amadzi azikhala okonzeka kuti atenge filimu yamadzi yofananira, yomwe imalepheretsa mapangidwe a madontho a nkhungu, sizimakhudza kuchotsedwa kwa zinthu zoyambira, komanso kukhala ndi malingaliro abwino.Huzheng ❖ kuyanika anayambitsa nanometer titaniyamu okusayidi particles pamaziko a multicomponent polymerization, ndipo nthawi yaitali odana ndi chifunga ndi kudziyeretsa ntchito analandira.Panthawi imodzimodziyo, kuuma ndi kuvala kukana kwapamwamba kumakhalanso bwino kwambiri.PWR-PET ndi zokutira za hydrophilic anti-fogging za PET gawo lapansi, lomwe ndi loyenera kuchiritsa kutentha komanso losavuta kupaka mafakitale akuluakulu.

Parameter:

Mbali:

-Kuchita bwino kwambiri polimbana ndi chifunga, masomphenya omveka bwino ndi madzi otentha, palibe madzi otsika pamwamba;
-Ili ndi ntchito yodziyeretsa, kuyendetsa dothi ndi fumbi pamwamba ndi madzi;
-Kumamatira kwabwino, kukana madzi otentha, kupaka sikugwa, palibe kuwira;
-Kukana kwanyengo kwamphamvu, anti-fogging hydrophilic performance imatha nthawi yayitali, zaka 3-5.

Ntchito:

Amagwiritsidwa ntchito pa PET pamwamba kuti apange filimu kapena pepala la anti-fogging hydrophilic.

Kagwiritsidwe:

Malingana ndi mawonekedwe osiyanasiyana, kukula kwake ndi malo apansi a zinthu zoyambira, njira zogwiritsira ntchito zoyenera, monga kusamba kwa shawa, kupukuta kupaka kapena kupopera mankhwala kumasankhidwa.Ndibwino kuti muyese kupaka m'dera laling'ono musanagwiritse ntchito.Tengani zokutira shawa mwachitsanzo kufotokoza njira zogwiritsira ntchito mwachidule motere:

Gawo loyamba: Kupaka.Sankhani luso lopaka loyenera lopaka;
Gawo lachiwiri: Mukapaka, imirirani kutentha kwapakati kwa mphindi zitatu kuti muwongolere;
Gawo la 3: kuchiritsa.Lowani mu uvuni, kutentha kwa 80-120 ℃ kwa mphindi 5-30, ndipo zokutira zimachiritsidwa.

Ndemanga:
1.Khalani osindikizidwa ndikusunga pamalo ozizira, pangani chizindikirocho kuti musagwiritse ntchito molakwika.

2. Khala kutali ndi moto, Pamalo amene ana sangafike;

3. Ventilate bwino ndi kuletsa moto mosamalitsa;

4. Valani PPE, monga zovala zoteteza, magolovesi oteteza ndi magalasi;

5. Letsani kukhudzana ndi pakamwa, maso ndi khungu, ngati mutakhudza, tsitsani madzi ambiri nthawi yomweyo, itanani dokotala ngati kuli kofunikira.

Kulongedza:

Kulongedza: 20 malita / mbiya;
Kusungirako: pamalo ozizira, owuma, popewa kutenthedwa ndi dzuwa.
