Wave beam guardrails, iri nzira yakakosha yezvipingamupinyi zve semirigid, anogadzirwa kubva kumarata ane marata akavharirwa uye anotsigirwa nematanda. Aya maguardrails anonyanya kugadzirwa kuti ashandiswe munzvimbo dzekunze, uko anoratidzirwa kune mamiriro emuchadenga sechiedza chezuva, okisijeni, ozone, shanduko yetembiricha, mvura uye hunyoro, uye kunyangwe tupukanana netumbuyu; zvese izvi zvine chekuita nehupenyu hwejasi rekudzivirira.
Iwo anorinda matanda esaisai ane hupenyu hwesevhisi kazhinji makore mashanu kusvika gumi apo ruvara rusingashanduke zvinooneka, pasina kuputika uye zvimwe zviitiko zvepasi. Iko kushongedza uye kutendeseka kwefirimu yayo yekuputira inochengetedzwa zvinobudirira; saka, kupikisa kwemamiriro ekunze kwehupfu hwekuputira kunonyanya kukosha.
Kuramba kwemamiriro ekunze ndiko kugona kwepoda yekupotera kuti ishingirire mamiriro emuchadenga kana ichishandiswa mukuratidzira kunze. Chikamu chakakosha ndechekudziya. Mwero wephotochemical reactions unowedzera zvakapetwa kaviri pakuwedzera kwegumi ° C tembiricha. Pamasaisai ese emwaranzi yezuva, wavelengths ari pakati pe250-1400nm akarova pasi. Yeiyo infrared mwaranzi (780-1400nm) inopa 42-60% yehuwandu hwemwaranzi yezuva, inonyanya kukanganiswa nemhando yekupisa kune zvinhu. Chiedza chinooneka (380-780nm), icho chinoumba 39-53% yehuwandu hwemwaranzi yezuva, inokanganisa chinhu mumhando mbiri dzekupisa uye kuita kwemakemikari. Ultraviolet radiation (250-400nm) inonyanya kukanganisa zvinhu kuburikidza nephotochemical chiitiko. Zvakawanikwa kuburikidza nezvidzidzo zvakasiyana-siyana kuti yakanyanya kuparadza ultraviolet mwaranzi papolymer resins ndeyewavelengths pakati pe290-400 nm uye inoshanda zvakanyanya paanenge 300nm. Iyi mhuri yewavelengths inokonzeresa kushatiswa kwepololefin resins.
Kudzivirirwa kwemamiriro ekunze kwejasi rehupfu kunogona, saka, kukwidziridzwa nekuzvitsaura maajenti izvo zvinotungamira mukuipa kwekupfeka uye maitiro avo ekugadzirisa. Kunyanya mumakore achangopfuura, kusarudzwa kwezvinhu zvakasvibirira uye kuwedzera maumbirwo, kusanganisa uye extrusion, pamwe nekukuya uye zvichingodaro, zvakafambiswa zvakanyanya muChina, zvichikonzera kuvandudzwa kwemamiriro ekunze.
Nekudaro, imwe pfungwa inofanirwa kutaurwa ndeyekuti mhando inosiyana zvakanyanya pakati pevagadziri vehupfu muChina. Vamwe vavo vanotoitira hanya purofiti kupfuura mhando, kucheka mitengo, kudzokorodza zvinhu zvakabikwa, uye kuwedzera zvakachipa zvekuwedzera izvo zvisina kuedzwa zvakakwana. Mhedzisiro yacho mabhanhire asina kunaka anopera uye anotsemuka nguva isati yakwana. Kusiyana neizvi, yakanaka mhando yehupfu yekupotera inogona kubatsira kuchengetedza wave danda rekuchengetedza munzvimbo inoshanda kwemakore 5-10 uye kureba.
Zvichakadaro, mvura inonaya inogona kupa hydrolysis uye kunyudzwa kwemvura, izvo zvinokanganisa firimu rekuvhara. Panguva imwecheteyo, inogona zvakare kugeza tsvina uye zvigadzirwa zvekuchembera kubva pairindarail, zvichideredza basa rekudzivirira uye kuchembera.
Kuramba kwemamiriro ekunze kunogona kuongororwa pachishandiswa kukurumidza uye bvunzo dzemamiriro ekunze. Kubva pakukurumidza kuongororwa kwemamiriro ekunze, fungidziro pamusoro pekuenderana kunze kwekuchembera nguva inogona kuwanikwa pamusoro pemamiriro ekunze. Mukuenzanisa, bvunzo dzekufumurwa dzechisikigo dzichawana mhedzisiro yechokwadi; zvisinei, miedzo iyi ichapedza nguva yakawanda.
