Chii chinonzi UV 292 CAS 82919-37-7?

UV 292 imvura yemwenje inodzikamisa iyo inogona kuwedzera nguva yekubuda kunze kwemapurasitiki akasiyana uye machira. Panguva yekugadzirisa, haiburitse kunhuhwirira nemapolymers kana kukanganisa ruvara rwepakutanga rwezvinhu. Haisi nyore kushanduka panguva yekupisa-kupisa uye ine yepamusoro polymer inoenderana.

UV 292 inogadzika mwenje inoumbwa nemusanganiswa wemaesita maviri, ine synergistic mhedzisiro ine benzotriazole UV inopfenyura uye inogona kudzivirira nemazvo mabhachi kubva pakuputika uye kusvuuka kwepasi pasi pekuratidzwa kwezuva.

Application

UV 292 inonyanya kushandiswa mune organic mapolima akadai se polyethylene, PVC, PVB, ABS resin, polyester, uye polyurethane. Kunyanya kukodzera polyurethane, sezvo Chiedza stabilizer 292 ine yakanaka solubility muzvinonyungudutsa.

UV 292 yakanyatsokodzera machira emota uye maindasitiri ekupfeka. Pendi yehuni, mwenje unoomesa maindasitiri machira, PU resin, anonamira uye mamwe mapurasitiki.

UV 292 ine yakanaka synergistic mhedzisiro kana yakashandiswa pamwe chete nebenzotriazole mhando yeUV absorbers, iyo inogona kuvandudza zvakanyanya kupikisa kwemamiriro ekunze echigadzirwa, zvirinani pane kushandisa UV absorbers chete. Nekuwedzera ma dispersants akakodzera, Chiedza stabilizer 292 inogona kunyatsokodzera mvura-based coatings.
