Zogulitsa zambiri zomwe zimagwiritsidwa ntchito tsiku ndi tsiku monga chigoba chachipatala, minofu, malaya, ndi zina zambiri, zimakhala ndi muyezo wosakondera wamakampani kuti uwongolere zabwino pazambiri ting'onoting'ono. Miyezo iyi imawonetsetsa kuti ogula atha kulandira katunduyo mokhutitsidwa, ndipo opanga akuyenera kuwongolera njira ndi khalidwe lawo mosalekeza. Muyezo woyeserera udzasinthidwa munthawi yake kuchokera ku malipoti masauzande ambiri oyeserera ndi mayankho amakasitomala akamagulitsa.
Ponena za PE tarp kapena Vinyl tarp test, pali mayesero ambiri ogwira ntchito monga colorfastness, abrasion-resistant, misozi, etc.
Ndi mfundo ziti zofunika kwambiri pakuyesa kwa Polyethylene kapena Vinyl UV Resistant?
● Mulingo Wowala
Ma radiation a UV ndi ochulukirapo, kuyambira <0.1nm mpaka> 1mm. Kuwala kwamphamvu kwambiri kwa dzuwa kumakhala pakati pa 300-400nm, kuwala kwa UV kwautali komwe kumakhudzana ndi kuwononga khungu lathu, koma kumakhudza kuwonongeka kwa ma polima ambiri azinthu zomalizidwa monga polyethylene kapena Vinyl.
PE tarp itha kugwiritsidwa ntchito kwa zaka 1-2. Koma kwenikweni, malo okhala ndi ukalamba wambiri amatha kuchepetsa kwambiri moyo wa tarps. Asanayesedwe ndi UV, katswiriyo adzayika zinthu zina zowonjezera zachilengedwe monga mvula, kutentha, chinyezi, kuwala kwa dzuwa, ndi zina zomwe zimatengera kukalamba mumakina. Mulingo wa kuwala udzakhala 0.8-1.0 W/㎡/nm, mofanana ndi kuwala kwa dzuwa kwenikweni.
● Mitundu ya Mwanawankhosa & Zopempha
Nyali za fluorescent ultraviolet zitha kugwiritsidwa ntchito pa mayeso a ASTM G154. Chifukwa cha mitundu yosiyanasiyana ya zinthu zopanda zitsulo, mafotokozedwe a magetsi adzakhala osiyana. Gulu lachitatu loyang'anira lidzalemba tsatanetsatane wa nyali mu lipotilo.
Kutentha kwamkati kwa labotale & mtunda wa radiation udzakhudzanso kuchuluka kwenikweni kwa ma radiation omwe amalandiridwa ndi zitsanzo za nsalu. Chifukwa chake gawo lomaliza la radiation litanthauza chodziwikiratu.
● Momwe Mungapitirire Mayeso Olimbana ndi UV
Poyamba, chitsanzo cha nsalu chidzadulidwa ndi 75x150mm kapena 75x300mm ndiyeno kukonza ndi aluminiyumu kuzungulira. Ikani chitsanzo mu chipinda choyesera cha QUV ndikuyika magawo onse.
0, 100, 300, 500, 750, 1000, 1500, 2000 maola akhoza kuthandizidwa. Chipinda choyesera cha QUV chili ndi ntchito yolimbikitsa yofulumizitsa ndi 4x 6x 8x…
Ponena za tarp ya PE kapena Vinyl, ndizokwanira kuti zitsanzo zilandire kuwonekera kwa maola 300-500. Pambuyo pake, katswiri wa labotale adzayamba mayeso otsatirawa, monga colorfastness, kukana misozi, kukana madzi. Poyerekeza ndi chitsanzo choyambirira, lipoti lomaliza lidzalembedwa.
