ʻOiai ua kaupalena ʻia e nā ʻano polymers a lākou e hana pū ai, ʻoi aku ka maikaʻi o nā UV stabilizers i ka pale ʻana i nā mea mai ka pōʻino ultraviolet. Loaʻa i nā Stabilizers ka pōmaikaʻi o ka pale ʻana i ka pōʻino wela, ʻaʻole hana kekahi mea absorbers a quenchers. I ka wā e pono ai ka pāhana i ka pale mai ka wela, hāʻawi ʻo HALS i ʻelua wela a me ka pale ʻana i ka pōʻino māmā. ʻO ka mea hoihoi, hoʻokomo nā wānana i ka HALS ma ke ʻano o ka mea hoʻohui UV i kaulana loa ae ulu nui loa mai 2016 a hiki i 2021. ʻO nā noi he nui no HALS, i ka hoʻohui ʻana i kahi mākeke e ulu nei no nā plastics, e hana i kēia wānana i kahi kūlana kiʻekiʻe.
Ke koi aku nā huahana lahilahi i ka pale ultraviolet, ʻoi aku ka maikaʻi o ka HALS ma mua o nā mea hoʻopale UV. Loaʻa i kēia huahana he -ʻano like ʻole. ʻO ka nui o nā paona molekala e hiki ai iā ia ke hoʻohana i nā uhi a me nā plastics. Hiki i ka Polypropylene a me nā polymers ʻē aʻe ke hoʻohana i ka HALS i ka wā o kā lākou hana ʻana, e komo pū ana ma nā pae o ka pepa a i ʻole ka extrusion profile a me ka puhi ʻana a i ʻole ka hoʻoheheʻe ʻana.
No ka mea ʻaʻole pili ka mānoanoa i ka hana o HALS, ʻaʻole pono nā pākēneka i hoʻohana ʻia a me ka hohonu o ka huahana i nā ana nui. ʻOiai ʻoi aku ka maikaʻi o ka hana ʻana o nā UV absorbers inā hiki iā lākou ke loaʻa i kahi papa mānoanoa a i ʻole ka ʻike kiʻekiʻe e hoʻomaikaʻi ai i ka pale, hana maikaʻi ʻo HALS me nā haʻahaʻa haʻahaʻa. No nā noi ma nā papa polimer lahilahi a i ʻole ka lōʻihi o ka pale ʻana o UV, ʻoi aku ka maikaʻi o nā stabilizers e like me HALS i ka wā e hana ai me nā polymers kūpono. No nā nīnau e pili ana i ka pili ʻana o nā polymers me HALS a i ʻole nā mea hoʻohui UV ʻē aʻe,e kelepona mai iā mākou ma ka pūnaewele.
