Xabagta UV (UV) waa nooc ka mid ah resin sawir-qaade leh oo miisaankiisu yar yahay.Waxay leedahay kooxo fulin kara falcelinta daweynta UV, sida curaarta labajibbaaran ee kala duwan ee aan saturated ama kooxaha epoxy-ga.Waa qaybta ugu muhiimsan ee alaabta daweynta UV (daahan UV, khad UV, xabagta UV, iwm.), iyo waxqabadkeedu wuxuu asal ahaan go'aamiyaa waxqabadka ugu muhiimsan ee alaabta la daaweeyay.
Waqtigan xaadirka ah, xabagta gudaha ee UV ee la daweyn karo inta badan waxaa ka mid ah epoxy acrylate, poliurethane acrylic resin, polyester acrylic resin, amino acrylic resin iyo sawir sawir alkali resin soluble.
Astaamaha iyo codsiyada noocyada kala duwan ee haraaga UV ee la daweyn karo
1. Epoxy acrylic resin waa kan ugu isticmaalka badan iyo xadiga ugu badan ee xabagta UV ee wakhtigan xaadirka ah.Sababtoo ah habka isku-dhafka fudud, ilaha ku habboon ee alaabta ceeriin, qiimo jaban, xawaaraha iftiinka degdega ah, engegnaanta sare, dhaldhalaalka sare, caabbinta kiimikada wanaagsan, caabbinta kulaylka wanaagsan iyo guryaha korantada, resin epoxy acrylic waxaa si ballaaran loo isticmaalaa sida resin ugu weyn ee iftiinka. warqad la daweeyay, alwaax, caag iyo dahaar bir ah, khad khafiif ah oo la daweeyay iyo koollada khafiifka ah ee la daweeyay.Noocyada ugu waaweyn waa bisphenol A epoxy acrylic resin, phenolic epoxy acrylic resin, epoxy oil acrylate iyo noocyo kala duwan oo resin epoxy acrylic ah oo la bedelay.
2. Xabagta acrylic polyurethane sidoo kale waa mid si weyn loo isticmaalo, xaddi badan oo xabagta nalka lagu daweeyo.Polyurethane acrylic resin waxaa si weyn loogu isticmaalaa warqadda la daweyn karo UV, alwaax, caag iyo daahan biraha ah, khadadka daweyn karo UV iyo xabagta daweyn UV sababtoo ah sifooyinkeeda dhameystiran oo aad u wanaagsan, sida caabbinta xirashada iyo dabacsanaanta, caabbinta kiimikada wanaagsan, caabbinta saamaynta iyo guryaha korontada filimka la daweeyay, iyo ku dhejinta wanaagsan ee balaastikada iyo substrates kale.Noocyada ugu muhiimsan waa caraf udgoon iyo aliphatic polyurethane acrylic resin.
3. Polyester acrylic resin sidoo kale waa resinka nalka ee inta badan la isticmaalo.Sababtoo ah xabagta ayaa leh ur yar, xanaaq yar, dabacsanaan wanaagsan iyo qoynta midabka, waxaa badanaa loo isticmaalaa rinjiga midabaynta iftiinka iyo iftiinka iftiinka oo ay weheliso resin epoxy acrylic iyo resin polyurethane acrylic.
4. Amino acrylic resin waxaa inta badan loo isticmaalaa daaha UV dawayn karo iyo UV la daweyn karo oo ay la socdaan epoxy acrylic resin iyo polyurethane acrylic resin sababtoo ah caabbinta kulaylka wanaagsan iyo caabbinta cimilada, caabbinta kiimikada wanaagsan iyo engegnaanta sare.
5. Sawirka sawirka alkali resin soluble waa resin si gaar ah loogu isticmaalo sawir-qaadista alxanka dareeraha ah.Waxay ka kooban tahay kooxaha karboksylka waxaana lagu soo saari karaa oo lagu sawiri karaa biyo alkaline ah.Filimka la daaweeyay wuxuu leeyahay sifooyin koronto oo aad u wanaagsan, caabbinta kiimikada iyo iska caabinta kulaylka.Noocyada ugu waaweyn waa copolymer maleic anhydride copolymer iyo epoxy acrylic resin oo lagu beddelay maleic anhydride.
