Imikhiqizo eminingi esetshenziswa nsuku zonke efana nemaski yezokwelapha, izicubu, ihembe, njll. Lezi zindinganiso ziqinisekisa ukuthi abathengi bangathola izimpahla ngokwaneliseka, futhi abakhiqizi badinga ukuthuthukisa inqubo yabo kanye nekhwalithi ngokuqhubekayo. I-Test Standard izovuselelwa ngesikhathi kusuka ezinkulungwaneni zemibiko yokuhlola namakhasimende 'ngemuva kokuthengisa impendulo.
Ngokuqondene ne-TARP ye-PE TARP noma ukuhlolwa kwe-Vinyl Tarp, kunezivivinyo eziningi ezisebenzayo ezinjengembala, ukungazweli, ukumelana nezinyembezi, ukumelana nezinyembezi, ngizokwethula inqubo ebalulekile yokuhlola ukumelana ne-UV.
Yimaphi amaphuzu abucayi we-polyethylene noma ukuhlolwa kwe-vinyl UV ongavili?
● I-Irradiance Level
Ububanzi bemisebe ye-UV bubanzi, kusuka ku- <0.1nm kuya> 1mm. I-Sunlight Ultra - Ubudlova buphakathi kuka-300-400nm, i-wavelength ende ye-UV ehlobene nengozi esikhunjeni sethu, kepha ithinta ukonakaliswa okuningi kwama-polymers ama-polyethylene noma i-vinyl.
I-TA TARP ingasetshenziselwa iminyaka engu-1-2. Kepha eqinisweni, imvelo enezinto eziningi zokuguga kakhulu inganciphisa kakhulu impilo ye-tarps. Ngaphambi kokuhlolwa kwe-UV, uchwepheshe uzobeka izinto eziningi ezengeziwe zezemvelo ezifana nemvula, izinga lokushisa, umswakama, ukubonakaliswa kwelanga, namanye amapharamitha ukulwemela inqubo yokuguga emshinini. Izinga le-Irradiance lizoba ngu-0.8-1.0 w / ㎡ / nm, elifana nelanga langempela.
● Izinhlobo ze-Vamb nezicelo
Izibani ze-ultraviolet ze-fluorescent zingasebenza ekuhlolweni kwe-ASTM G154. Ngenxa yezinhlobo ezahlukahlukene zemikhiqizo engeyona yensimbi, imininingwane yamalambu izohluka. Iqembu lesithathu lokuqondisa lizophawula imininingwane yesibani embikweni.
Izinga lokushisa lasendlini lasendlini nebanga le-radiation lizophinde libe nomthelela enanini langempela lemisebe etholwe isampula yendwangu. Ngakho-ke i-parameter yokugcina yemisebe izobheka umtshina othize.
● Ungaqhubeka kanjani uhlolo lokumelana lwe-UV
Ekuqaleni, isampula yendwangu izonqunywa ngu-75x150mm noma i-75x300mm bese ilungisa nge-aluminium loop. Beka isampula egumbini lokuhlola le-Quv bese usetha wonke amapharamitha.
0, 100, 300, 500, 750, 1000, 1000, amahora angama-2000 angasekelwa. I-QuV Test Chamber inesivuseleli sokusheshisa nge-4x 6x 8x ... Uma ipharamitha ingu-8x, izodinga amahora angama-125 kuphela ukuvuselela ukubonakaliswa kwamahora ayi-1000 wemvelo.
Mayelana ne-PE noma i-Vinyl Tarp, yanele amasampula ukuthola ukubonakaliswa kwamahora angama-300-500. Emva kwalokho, isazi selebhu sizoqala lesi sivivinyo esilandelayo, njengokubala umbala, ukumelana kwezinyembezi, ukumelana kwamanzi. Uma kuqhathaniswa nesampula yangempela, kuzobhalwa umbiko wokugcina.
