Kedu isi ihe dị oke egwu nke ule Polyethylene ma ọ bụ Vinyl UV Resistant?
● Ọkwa ikuku
Ogologo radieshon UV dị ukwuu, site na <0.1nm ruo>1mm. Ìhè anyanwụ ultra-ime ihe ike dị n'etiti 300-400nm, ogologo wavelength UV metụtara obere emerụ anyị akpụkpọ, ma na-emetụta ọtụtụ polymers 'mmebi nke ọtụtụ polymers okokụre ngwaahịa dị ka polyethylene ma ọ bụ Vinyl.
Enwere ike iji PE tarp maka afọ 1-2. Mana n'ezie, gburugburu ebe nwere ọtụtụ ihe ịka nká nwere ike ibelata ogologo ndụ nke tarps.
