no ka mea, pale kaʻa maopopo, ʻO ka pilikia o ka melemele e like me ka ʻelemakule kanaka. Ma hope o ka lōʻihi o ka hoʻohana ʻana, e ʻelemakule a huli melemele me ka hoʻoneʻe ʻana o ka oxidation a me nā kukui ultraviolet. Akā ʻo ka pilikia kekahi ʻoni ʻoni pale pena hiki ke mau makahiki he ʻumi me ka melemele ʻole, ʻoiai kekahi ppf film huli melemele a ʻelemakule ma hope o hoʻokahi a ʻelua paha makahiki o ka hoʻohana ʻana. 

He aha ka pilikia?

E pili ana i ka mākeke o kēia manawa, ʻo ka ʻokoʻa nui i ka mea. ʻO kēlā mau ppf uhi ʻO nā mea i emi iho ma mua o hoʻokahi a ʻelua paha makahiki i hana ʻia me ka mea PVC. He ʻuʻuku ka waiwai maka a ʻoi aku ka nui o ka loaʻa kālā. Ke hilinaʻi wale nei nā mea PVC i ka paʻakikī e pale aku i ka pōʻino o waho i ke kaʻa kumu. ʻAʻole nui ka hopena o ka pōʻino o ka pena i ka pale ʻana i ka melemele, no laila ka kiʻi pale kaʻa e melemele koke.

E lohi iki ka māmā melemele o ka uhi kaʻa TPU, no ka mea, aia kekahi hana anti-yellowing, akā e ʻike mau ana ka melemele ma hope o ʻekolu makahiki o ka hoʻohana ʻana. E like me nā kānaka, inā makemake ʻoe e pale i ka ʻelemakule, pono ʻoe e hana i nā hana he nui. maʻamau, KPAL PLUS moʻoppf uhi hiki iā ia ke hōʻoiaʻiʻo ʻaʻohe melemele no nā makahiki he ʻumi e hoʻohana i kahi papa o ka ʻenehana uhi ma ke kumu o nā mea TPU, i loaʻa i nā uhi kaʻa kahi hana anti-yellowing lōʻihi.
