No ke aha e hoʻohuli ai nā hōʻailona alanui? Ka hana o ka uv & resin i ka wā

ʻO ke alahele alanui ma keʻano he nui o ke kalaʻana e ka uv degradation a resin i keʻano o keʻano a me ka palekana. Eia pehea lākou e kamaʻilio ai:

1. Hōʻino ka UV
ʻO ka ultraviolet altraviolet (Uv) Rays e wāwahi i nā mea i loko o nā mea e komo ai i nā mea hōʻailona. No nā hōʻailona TROMMUPPPPPESS, UV Disposure i nā pale o nā pale (e.g., C5 Petroleum Resin) ʻO nā māka keʻokeʻo keʻokeʻo me ka haʻahaʻa ma Titanium Dioxide (Tio₂) i nāʻike i ka wikiwiki, e like me Tigrades e kū'ē iā UV akā e hana i ka manawa.

2. Resing Safenging
ʻO nā hoʻopakele nā Thermoplastic i nā mahana kiʻekiʻe (180-230 ° C), ka hoʻopiʻiʻana. ʻO ka neʻeʻana i ka wā o ka noi a iʻole ka lōʻihi o ka hōʻikeʻana o ka lā i ka wikiwiki o ka resin degradation, alakaʻi i ka melemele.
ʻO nā pale TUMUT TPU (hoʻohanaʻia i kekahi mau kapa) i ka lole uv-indiding uv-induced ma muli o nā kiʻi o ka benzene e like me keʻano he nui.
Nā hopena
E hoʻohui iā Uv Distsorbers
E hoʻohana i nā nohona kiʻekiʻe kiʻekiʻe a me ka lawa o Tio₂ (≥18%) e hoʻomaikaʻi ai i ke kū'ēʻana.
E kāohi i ka mahana noi (180-200 ° C) e pale ai i ka degradation thermal.
Ma ka heluʻana i ka UV a me Resin Stopibility, hiki i nā hōʻailona alanui ke mālama i ke kala a me ka hana lōʻihi.
