Muaj ntau qhov laj thawj rau yellowing ntawm FRP cov khoom:
1. Thaum lub sij hawm synthesis ntawm unsaturated resin esterification, vim thermal aging yellowing tshwm sim los ntawm qhov kub thiab txias, qhov kub ntawm cov iav steel ntawv nyob nruab nrab ntawm -30 degree ~ ntxiv rau 130 degree. Yog hais tias qhov kub thiab txias tshaj qhov ntau, cov resin yuav yooj yim tig daj, uas yuav cuam tshuam rau cov tsos ntawm cov khoom resin. ;
2. Lub yellowing ntawm cov resin tshwm sim los ntawm raug ultraviolet lub teeb yuav yog vim lub thermal oxygen degradation ntawm lub compound ntawm resin nws tus kheej nyob rau hauv high kub, nws yog nquag mus rau hluav taws xob hloov, ua rau cov resin daj;
3. Nyob rau hauv cov txheej txheem ntawm resin ntau lawm, cov ntaub ntawv raw yog raug rau cov pa oxygen vim tsis zoo sealing ntawm lub cuab yeej thiab lwm yam yog vim li cas. Cov saw hlau tsis zoo polyester molecular tsis tsuas yog muaj ester pawg, hydroxyl pawg, thiab carboxyl pawg, tab sis kuj muaj ob daim ntawv cog lus thiab cov nplhaib uas muaj ntxhiab. Cov kab mob oxygen tuaj yeem ua rau nws tshwm sim ntawm thermo-oxidative degradation, qhov pom tseeb tshaj plaws yog tias cov xim ntawm cov resin tig daj.
4. Kev cuam tshuam ntawm cov khoom ntxiv xws li antioxidants, polymerization inhibitors, curing agents, thiab lwm yam, amine antioxidants tau yooj yim hloov dua siab tshiab rau hauv nitrogen oxide dawb radicals rau xim cov khoom. Feem ntau siv polymerization inhibitors, xws li hydroquinone, yog thaum tam sim no, nws yog oxidized rau quinones, uas lawv tus kheej muaj xim, yog li cuam tshuam cov xim ntawm cov resin.
Piv txwv li, ultraviolet rays thiab thermal oxidation yog lub ntsiab tseem ceeb cuam tshuam rau yellowing ntawm FRP nplooj ntawv.Yog tias koj muaj lus nug txog FRP panels lossis koj xav yuav FRP panels, thov hu rau peb!
