Ama-wave beam guardrails, okuwuhlobo olubalulekile lwezivimbi ze-semigid, enziwe ngamaphaneli ensimbi enziwe uthayela axhumene futhi asekelwa izigxobo. Lezi zinsimbi zokuqapha zenzelwe ikakhulukazi ukusetshenziswa ezindaweni zangaphandle, lapho zichayeka khona ezimweni zomkhathi njengokukhanya kwelanga, umoya-mpilo, umoya-mpilo, i-ozone, ukuguquka kwezinga lokushisa, amanzi nomswakama, ngisho nezilwanyana ezincane nezinambuzane; konke lokhu kunomthelela esikhathini sokuphila kwento evikelayo.
Imigqa yokuqapha yemishayo yamagagasi inempilo yesevisi ngokuvamile eyi-5 kuya kweyi-10 lapho umbala ungashintshi ngokuphawulekayo, ngaphandle kokuqhekeka nezinye izinto ezingaphezulu. Umhlobiso nobuqotho befilimu yayo yokugqoka kugcinwa ngokuphumelelayo; ngakho-ke, ukumelana nesimo sezulu se-powder coating kukhulu kakhulu.
Ukumelana nesimo sezulu yikhono lempushana enamathelayo ukumelana nezimo zomoya lapho isetshenziswa ekuchayekeni ngaphandle. Ingxenye ebalulekile izinga lokushisa. Izinga lokusabela kwe-photochemical liphindeka kabili kukho konke ukukhuphuka kwezinga lokushisa okuyishumi °C. Kuwo wonke amaza emisebe yelanga, amaza aphakathi kuka-250-1400nm ashaya umhlaba. Emisebeni ye-infrared (780-1400nm) enikela ngo-42-60% wesamba semisebe yelanga, ethinteka kakhulu yimodi yokushisa ezintweni. Ukukhanya okubonakalayo (380-780nm), okwenza u-39-53% wesamba semisebe yelanga, kuthinta into kuzo zombili izindlela zokushisa nokusabela kwamakhemikhali. Imisebe ye-Ultraviolet (250-400nm) ithinta kakhulu izinto zokusebenza ngomsebenzi we-photochemical. Kutholwe ngocwaningo olwahlukene ukuthi imisebe ye-ultraviolet ebhubhisa kakhulu kuma-polymer resins ingama-wavelengths phakathi kuka-290-400 nm futhi esebenza kakhulu cishe ku-300nm. Lo mndeni wama-wavelengths unesibopho sokucekelwa phansi kwama-polyolefin resins.
Ngakho-ke, ukuvikelwa kwesimo sezulu samajazi empushana kungathuthukiswa ngama-agent ahlukanisayo aholela ekuwohlokeni kwezingubo kanye nezinyathelo zabo zokulungisa. Ikakhulukazi eminyakeni yamuva, ukukhethwa kwempahla eluhlaza kanye nokwakheka okungeziwe, ukuxuba nokukhipha, kanye nenqubo yokugaya nokunye, sekuthuthuke kakhulu eShayina, okuholela ekuthuthukisweni kokumelana nesimo sezulu.
Kodwa-ke, iphuzu elilodwa okufanele kukhulunywe ngalo ukuthi izinga lihluka kakhulu phakathi kwabakhiqizi be-powder e-China. Abanye babo baze bakhathalele inzuzo ngaphezu kwekhwalithi, ukunciphisa izindleko, ukuvuselela izinto zokusetshenziswa, futhi bengeze izithasiselo ezishibhile ezingahloliwe ngokwanele. Umphumela uba izimbotshana ezingezinhle ezifiphalayo futhi ziqhekeke ngaphambi kwesikhathi. Ngokuphambene, izimbotshana zempushana zekhwalithi enhle zingasiza ukugcina ama-wave beam guardrails esesimweni esisebenzisekayo iminyaka engu-5-10 nangaphezulu.
Phakathi naleso sikhathi, amanzi emvula angase abangele i-hydrolysis kanye nokumuncwa kwamanzi, okuphazamisa ifilimu yokumboza. Ngasikhathi sinye, ingaphinda igeze ukungcola kanye nemikhiqizo yokuguga isuka endaweni yokugada, inciphise umsebenzi wokuvikela kanye nenqubo yokuguga.
Ukumelana nesimo sezulu kungase kuhlolwe kusetshenziswa izivivinyo zesimo sezulu ezisheshayo nezemvelo. Kusukela ekuhlolweni kwesimo sezulu esisheshayo, ukubikezela mayelana nesikhathi sokuguga kwangaphandle kungatholwa mayelana nomthelela womkhathi. Uma kuqhathaniswa, ukuhlolwa kokuchayeka kwemvelo kuzozuza imiphumela engokoqobo; Nokho, lezi zivivinyo zizodla isikhathi esiningi.
