UV tiv thaiv yog hais txog kev tsim cov khoom siv lossis cov khoom lag luam kom tiv thaiv kev puas tsuaj lossis tawg ntawm kev kis nrog lub hnub ultraviolet (UV) hluav taws xob. UV Cov ntaub ntawv tiv thaiv feem ntau siv nyob rau sab nraum zoov cov khoom lag luam xws li cov ntaub, plastics thiab txheej ua kom txuas ntxiv lub neej thiab tswj cov khoom ntawm cov khoom.
Yog lawm, qee cov tarps tau tsim tshwj xeeb los ua UV tiv taus. Cov tarps no yog tsim los ntawm cov khoom kho uas tuaj yeem tiv thaiv lub hnub ci ntsa iab tsis muaj kev cuam tshuam lossis poob xim. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias tsis yog txhua tus Divps yog UV tiv taus thiab qee tus yuav ua tsis tau sijhawm yog tias raug rau hnub ci. Thaum xaiv ib tus Tarp, nws yog lub tswv yim zoo los tshawb xyuas daim ntawv lo lossis cov khoom lag luam tshwj xeeb kom paub tseeb tias nws tiv taus koj qhov kev xav tau.
Qeb ntawm UV tiv thaiv ntawm Tarps nyob ntawm lawv cov ntaub ntawv tshwj xeeb thiab UV Stabilizers siv hauv lawv cov khoom siv. Feem ntau, UV Resistant Tarps yog ntsuas los ntawm feem pua lawv thaiv lossis nqus UV hluav taws xob. Ib qho kev siv ntaus nqi feem ntau yog Ultraviolet Kev Tiv Thaiv Kev Tiv Thaiv (UPF), uas cov nqi cov ntaub raws lawv lub peev xwm los thaiv UV hluav taws xob. Qhov siab dua qhov kev ntaus nqi UPF, qhov zoo dua UV kev tiv thaiv. Piv txwv li, A UPF 50-rated Tarp Blocks txog 98 feem pua ntawm UV hluav taws xob. Txawm li cas los xij, nws yog ib qho tseem ceeb kom nco ntsoov tias qib kev tiv thaiv UV kuj tseem tuaj yeem nyob ntawm cov plaub hau, huab cua huab cua thiab tag nrho cov tarp zoo.
