Zvinogona kunetsa kuwana matt anopedzisa ne100% solids UV machira anorapika. Chinyorwa chechangobva kuitika chinotsanangura maajenti akasiyana uye anotsanangura kuti ndeapi mamwe magadzirirwo akakosha.
Chinyorwa chikuru chechangobva kubuda cheEuropean Coatings Journal chinotsanangura kuoma kwekuwana matt 100 % solids UV-coatings. Semuyenzaniso, zvigadzirwa zvevatengi zvinoratidzwa kuti zvinodzokororwa kupfeka uye zvinosvibisa mukati mehupenyu hwavo hwese, manyoro-anonzwa machira anofanirwa kuve akasimba. Nekudaro, kuyera kupfava kunzwa nekupfeka kuramba idambudziko rakakura. Zvakare kuwanda kwefirimu shrinkage chipingamupinyi mukuwana yakanaka matting maitiro.
Vanyori vakaedza musanganiswa wakasiyana-siyana wesilica matting agents uye UV reactive diluents uye vanoongorora rheology yavo uye chitarisiko. Muedzo wakaratidza kusiyanisa kwakanyanya kwemhedzisiro, zvichienderana nerudzi rwesilica uye diluent.
Uyezve, vanyori vakadzidza ultrafine polyamide powders iyo yakaratidza kushanda kwepamusoro matting uye yakave nemigumisiro shoma pane rheology kupfuura silicas. Seyechitatu sarudzo excimer pre-curing yakaongororwa. Iyi tekinoroji inoshandiswa muzvikamu zvakawanda zveindasitiri uye maapplication. Excimer inomirira "excited dimer", nemamwe mazwi dimer (eg Xe-Xe-, Kr-Cl gasi) iyo inofara kune yakakwirira simba nyika zvichitevera kushandiswa kwemagetsi anochinja. Nekuti idzi "zvinofadza dimers" hadzina kugadzikana dzinoparara mukati memananoseconds mashoma, ichishandura simba radzo rekusimudzira kuita mwaranzi yemaziso. Iyi tekinoroji yakaratidza mhedzisiro yakanaka, zvisinei mune zvimwe zviitiko.
Musi waChivabvu 29, Xavier Drujon, munyori wechinyorwa achatsanangura chidzidzo uye mhedzisiro panguva yedu yepamwedzi yepawebhu European Coatings Live. Kupinda pawebhusaiti hakuna muripo zvachose.
