I-Anti-inkungu i-coating luhlobo lwengubo enomsebenzi wokuthintela ukuxinana kwenkungu.
I-Super-hydrophilic coatings ene-angle yoqhagamshelwano lwamanzi engaphantsi kwe-15 ° iqala ukuba nemiphumo yokuchasana nenkungu.
Xa i-angle yoqhagamshelwano lwamanzi i-4 °, i-coating ibonisa ukusebenza kakuhle kwe-anti-inkungu.
Xa i-angle yoqhagamshelwano lwamanzi iphezulu kune-25 °, umsebenzi wokulwa nenkungu uphela ngokupheleleyo.
Kwiminyaka ye-1970 (1967), uFujishima Akira, uHashimoto kunye nabanye kwiYunivesithi yaseTokyo bafumanisa ukuba i-titanium dioxide (TiO2) inezixhobo ze-hydrophilic kunye nokuzicoca [1].Nangona kunjalo, xa i-titanium dioxide ingakhanyisi ngokukhanya kwe-ultraviolet, i-angle yokudibana kwamanzi yi-72±1 °.Emva kokuba ukukhanya kwe-ultraviolet kulayishwe, isakhiwo se-titanium dioxide sitshintsha, kwaye i-angle yoqhagamshelwano lwamanzi iba yi-0±1 °.Ke ngoko, inqanyulwe kukukhanya kwe-ultraviolet xa isetyenziswa [2].
Kukho enye indlela ye-anti-fog coatings-sol-gel indlela (sol-gel) [3] inkqubo ye-nano-silica (SiO2).Iqela le-hydrophilic lidibene nesakhelo se-nano-silica, kwaye zombini isakhelo se-nano-silica kunye ne-organic-inorganic substrate inokwenza i-chemical bond eqinile.I-sol-gel echasene nenkungu iyaxhathisa iyakwazi ukukhuhla, ugwebu kunye nezinyibilikisi.Yomelele ngakumbi kuneyaleko yokuchasana nenkungu, ibhityile kakhulu kuneengubo zepolymer ezichasene nenkungu, ngokuchaneka okuphezulu, izinga eliphezulu lokutyabeka kunye noqoqosho ngakumbi.

Xa umphunga wamanzi ashushu udibana nokubanda, uya kwenza umaleko wenkungu yamanzi phezu kwento, eyenza umbono ocacileyo wokuqala ube mfiliba.Ngomgaqo we-hydrophilic, i-Huzheng i-anti-fogging hydrophilic coating yenza ukuba amaconsi amanzi abekwe ngokupheleleyo ukuze afumane ifilimu yamanzi afanayo, okuthintela ukubunjwa kwenkungu, ayichaphazeli ukucocwa kwezinto ezisisiseko, kwaye igcina ingqiqo ebonakalayo.I-Huzheng i-coating yazisa i-nanometer titanium oxide particles ngesiseko se-polymerization ye-multicomponent, kunye nexesha elide lokuchasana ne-fogging kunye nomsebenzi wokuzicoca ufunyenwe.Ngelo xesha, ubunzima kunye nokuxhatshazwa kokugqoka kwendawo kuphuculwe kakhulu.I-PWR-PET yi-hydrophilic anti-fogging coating ye-PET substrate, efanelekileyo kwinkqubo yokunyanga ubushushu kwaye ilungele ukugquma kwamashishini amakhulu.

Ipharamitha:

Uphawu:

-Umsebenzi ogqwesileyo wokulwa nenkungu, umbono ocacileyo ngamanzi ashushu, akukho manzi ahla phezu komhlaba;
-Inomsebenzi wokuzihlambulula, ukuqhuba ukungcola kunye nothuli phezu kwamanzi;
-Ukubambelela okugqwesileyo, ukunyanyiswa kwamanzi abilayo, ukugquma akuwi, akukho bubble;
-Ukuchasana kwemozulu okunamandla, ukusebenza kwe-hydrophilic anti-fogging kuhlala ixesha elide, iminyaka emi-3-5.

Isicelo:

Isetyenziselwa umphezulu we-PET ukuvelisa ifilimu ye-hydrophilic echasene nenkungu okanye iphepha.

Ukusetyenziswa:

Ngokwemilo eyahlukeneyo, ubungakanani kunye nomgangatho ophezulu wezinto ezisisiseko, iindlela ezifanelekileyo zokusetyenziswa, ezifana nokugubungela ishawa, ukusula ukuhlamba okanye ukutshiza kukhethwe.Kucetyiswa ukuba uzame ukutyabeka kwindawo encinci ngaphambi kokuba ufake isicelo.Thatha ishawa yokwambathisa umzekelo ukuchaza amanyathelo esicelo ngokufutshane ngolu hlobo lulandelayo:

Inyathelo lokuqala: Ukwaleka.Khetha itekhnoloji yokwaleka efanelekileyo yokwaleka;
Isinyathelo se-2: Emva kokugquma, yima kwiqondo lokushisa kwegumbi imizuzu emi-3 ukwenza inqanaba elipheleleyo;
Inyathelo lesi-3: ukunyanga.Faka i-oven, uyitshise kwi-80-120 ℃ imizuzu emi-5 ukuya kwe-30, kwaye i-coating iphilisiwe.

Amanqaku:
1.Gcina itywina kwaye ugcine kwindawo epholileyo, yenza ileyibhile icace ukuphepha ukusetyenziswa kakubi.

2 Yiba kude nomlilo, kwindawo abangenakufikelela kuyo abantwana;

3. Ventilate kakuhle kwaye unqande umlilo ngokungqongqo;

4. Nxiba iPPE, njengempahla ekhuselayo, iiglavu ezikhuselayo kunye nezibuko;

5. Vimbela ukudibanisa nomlomo, amehlo kunye nesikhumba, xa kukho nawuphi na uqhagamshelwano, uhlambe ngamanzi amaninzi ngokukhawuleza, biza ugqirha ukuba kuyimfuneko.

Ukupakisha:

Ukupakisha: iilitha ezingama-20 / umgqomo;
Ugcino: kwindawo epholileyo, eyomileyo, ukuthintela ukugqatswa lilanga.
