UV resin, oo loo yaqaan resin photosensitive, waa oligomer kaas oo ku dhici kara isbeddelo jidheed iyo kiimiko ah wakhti yar ka dib marka uu ifka soo gaadho, ka dibna isku xidho oo adkeeyo.Xabagta UV inta badan waxa loo qaybiyaa dareeraha ku salaysan UV resin iyo resin-biyood ku salaysan.
Xabagta UV ku salaysan millatariga
Walxaha caadiga ah ee ku salaysan UV resins inta badan waxaa ka mid ah: UV polyester unsaturated, UV epoxy acrylate, UV polyester acrylate, UV polyester acrylate, UV xabagta acrylic saafi ah, UV resin UV epoxy, UV silicone oligomer, iwm.
Biyo-baxa UV-ga
Xabagta UV ee biyaha ka dhasha waxaa loola jeedaa xabagta UV ee biyaha ku milma ama lagu kala firdhi karo biyo.Moleekulku waxa uu ka kooban yahay tiro cayiman oo ah kooxaha hydrophilic xoog leh, sida karboxyl, hydroxyl, amino, ether, iyo kooxaha acylamine;Waxa kale oo ku jira kooxo aan dherayn, sida acryloyl, methacryloyl ama kooxaha allyl.Geedaha UV ee biyaha ka dhasha waxa loo qaybin karaa saddex qaybood: lotion, biyaha la firdhi karo iyo biyaha milmaya, oo ay badi ku jiraan saddex qaybood: polyurethane acrylate waterborne, epoxy acrylate waterborne iyo polyester acrylate waterborne.
Xabagta UV ee biyaha ka dhasha guud ahaan waxa ay ka kooban tahay 80-90% xabagta biyaha ka dhasha iyo 10-20% daroogo kale.Daahfurka ka dib iyo suufka, lakab khafiif ah oo ka kooban polymer ayaa ku hadhay dusha sare ee substrate-ka, kaas oo ku siinaya daahan sifooyin kala duwan sababtoo ah isku-dhafka caanaha ee kala duwan.Sida dhaldhalaalka sare, matte, abrasion adkaysta, iwm.
Xabagta biyaha ka dhasha ayaa ah qaybta ugu muhiimsan ee Z ee xabagta UV ee biyaha.Waxay go'aamisaa oo ay saamaysaa sifooyinka biyaha ee xabagta UV, sida dhalaalka, dhejiska, caabbinta abrasion, qallayl, iwm. Sidaa darteed, xulashada saxda ah ee xabagta UV ee biyaha ayaa fure u ah keenista guusha leh ee xabagta UV ee biyaha.
Waxaa jira noocyo badan oo xabagta, oo ay ku jiraan rosin waterborne modified xabagta lab ah, xabagta polyurethane biyo ah, xabagta acrylic waterborne, waterborne resin waterborne, waterborne xabagta biyaha, iwm. sii daynta biyaha, dhalaalid wanaagsan ka dib sameynta filimka, caabbinta kulaylka, caabbinta kiimikada, xawaaraha qalajinta degdega ah, iwm.Sidaa darteed, marka la diyaarinayo xabagta UV ee biyaha ka dhasha, nidaamka copolymer acrylic acrylic waterborne ayaa noqda doorashadayada ugu fiican.
Aqueous acrylic copolymer resin waxa loo qaybin karaa xal acrylic aqueous, firidhsan acrylic aqueous, iyo lotion acrylic.Kareemka acrylic waxaa loo qaybin karaa kareemka akril-sameeyaha ee filim-samaynta iyo kareemka acrylic-ga oo aan samaynayn filim.Astaamaha xabagta acrylic copolymer waterborne waxay ka kooban yihiin monomers.Waxqabadka iyo habka isku-dhafka.Qaar ka mid ah monomers waxay hagaajin karaan dhalaalka iyo adkaanta, halka kuwa kalena ay bixin karaan iska caabin kiimikaad iyo dhejis.Tijaabooyin badan ayaa caddeeyey in xuubka UV ee biyaha ka dhasha, kaas oo si cilmiyeysan loogu daray dareeraha acrylic acid iyo kareemka acrylic acid, uu leeyahay sifooyin ku habboon.
