UV resinndicho chikamu chikuru cheUV kurapa system.Iyo oligomer inogona kuitika mumuviri uye makemikari shanduko munguva pfupi mushure mekuratidzwa kune UV mwenje, uye nekukurumidza kuyambuka uye kurapa.Mushure mekuporeswa kweUV coating, kuita kwekutanga kweiyo firimu rekupfekedza kunoenderana zvakanyanya neiyo huru yekugadzira firimu - UV resin, uye kuita kweUV resininotemerwa ne macromolecular polymer inoumba resin iyi.Iyo molecular chimiro, uremu hwemamorekuru, kaviri bond density uye tembiricha yegirazi yepolymer ichakanganisa mashandiro eresin.Iyo yechinyakare ine mafuta UV resin ine hombe mamorekuru uye viscosity, saka ine zvikanganiso mukuputira maitiro uye firimu kuita kutonga.Acrylateactive diluent [1] ine unsaturated kaviri zvisungo uye ine yakaderera viscosity.Kuiwedzera kune UV yekurapa sisitimu inogona kuderedza resin viscosity, kunatsiridza muchinjika-inobatanidza density yeresin, uye kunatsiridza kuita kwefirimu resin, saka inoshandiswa zvakanyanya.Nekudaro, mazhinji anoshanda diluent ane chepfu uye anogumbura ganda remunhu, mucous membrane uye maziso.Uye zvakare, iyo diluent yakaoma kuita zvakakwana panguva yekuvhenekesa kweUV, uye yakasara monomer inozokanganisa zvakananga kushanda kwenguva refu kweiyo firimu inorapa, iyo inomisa kushandiswa kwayo mukurongedza zvinhu zvehutsanana hwekudya.
MvuraUV resinzvinoreva kuUV resininonyungudika mumvura kana inogona kuparadzirwa nemvura.Mamorekuru ayo ane humwe huwandu hwemapoka ehydrophilic akadai secarboxyl, hydroxyl, amino, ether kana amide mapoka, pamwe nemapoka asina kurongeka senge acryloyl, methacryloyl kana allyl mapoka.Parizvino, izere nemvuraUV resinskunyanya zvinosanganisira waterborne polyacrylate, waterborne polyester acrylate, waterborne epoxy acrylate uye waterborne polyurethane acrylate.
Serudzi rutsva rwepolymer, hyperbranched polymer ine spherical chimiro, nhamba huru yeanoshanda ekupedzisira mapoka, uye hapana kupindirana pakati pemacheni.Hyperbranched mapolymers ane zvakanakira kunyungudika nyore, yakaderera kunyungudika, yakaderera viscosity uye yakakwirira reactivity.Naizvozvo, mapoka e acryloyl uye mapoka e hydrophilic anogona kuunzwa kuti asanganise emvura ma UV anorapika oligomers, ayo anovhura nzira nyowani yekugadzirira kwemvura.UV resins.
