Isticmaal
Alaabtani waa xasiliye iftiin leh oo leh waxqabad wanaagsan, oo awood u leh inuu nuugo shucaaca UV ee 240-340 nm dhererka hirarka leh sifooyinka midabka iftiinka, aan sun ahayn, waafaqsanaanta wanaagsan, dhaqdhaqaaqa yar yar, habka sahlan ee iwm. Waxay ilaalin kartaa polymerka ilaa xadka ugu sarreeya. , waxay ka caawisaa in la yareeyo midabka.Waxa kale oo ay dib u dhigi kartaa jaalaha iyo carqaladaynta luminta shaqadiisa jireed.Waxaa si ballaaran loo codsadaa in PE, PVC, PP, PS, PC galaas organic, fiber polypropylene, ethylene-vinyl acetate iwm Intaa waxaa dheer, waxa ay leedahay saamayn aad u wanaagsan iftiinka-dejinta on qalajinta phenol aldehyde, varnish khamriga iyo acname, polyurethane, acrylate. , expoxnamei iwm.
