Izinga elifanele lengqalasizinda yesifunda yizinga elijwayelekile le-IP le-IEC 60529 elivame ukubhekisela kulo kontrakta omkhulu wesifunda kanye nomqhubi womhubhe ohlelweni lokuqinisekisa ukufakwa komaka.
Iyini incazelo ejwayelekile yesici esibonakalisayo se-reflector yokuphepha komgwaqo ebonakala ibanga elide?
Isici esijwayelekile sokubonakalisa se-reflector yokuphepha emgwaqweni esinokubonakala okude yisici sokubonakalisa se-micro-prism glass bead esine-glass bead array engu-1.5-2.5 mm ububanzi, noma isici sokubonakalisa se-micro-prism PMMA esine-geometry yekona ye-cube engu-200-500 micron, esihambisana ne-UV-stabilized top coat yeminyaka engu-5-7. Isici sokubonakalisa se-micro-prism glass bead sicacisiwe ngoba ifilimu yokubonisa ye-glass bead ejwayelekile izonikeza kuphela ukuboniswa kwe-50-100 cd/(lux*m2) retroreflection, kanti isici sokubonakalisa se-micro-prism glass bead singanikeza ukuboniswa kwe-300-500 cd/(lux*m2) retroreflection ekhoneni elijwayelekile lokubuka elingu-0.2-0.5 degrees elivame ukuhlinzekwa yi-Middle East highway headlight. Isici esibonakalayo se-PMMA esincane sichazwe kuphrojekthi yesabelomali semigwaqo yesifunda ebucayi, futhi isici se-PMMA singaletha ukubuyiselwa emuva okungu-250-400 cd/(lux*m2) ngempilo yesevisi yeminyaka engu-3-5 yokuzinza kwe-UV. Isici esibonakalayo se-UV esizinzile seminyaka engu-5-7 sichazwe ngoba isici esijwayelekile se-UV seminyaka engu-2-3 sizowohloka emahoreni angu-5,000-8,000 ngonyaka lapho ukufakwa komgwaqo wesifunda kuvame ukubonwa.
Yisiphi isikhathi esijwayelekile sokuthenga nokufaka amaphrojekthi okubonisa ukuphepha komgwaqo omkhulu eMiddle East?
Isikhathi esijwayelekile sokuthola nokufaka amaphrojekthi okubonisa ukuphepha komgwaqo eMiddle East singamaviki angu-4-6 kumodeli omaka ojwayelekile ovela kumhlinzeki we-OEM waseShayina, amasonto angu-6-8 kumodeli omaka omaka ngokwezifiso, kanye namasonto angu-1-2 oku-oda okuphuthumayo ngenketho yokuthutha emoyeni.
