Hoʻokuʻu i ka manawa:2026-01-21
He mea koʻikoʻi nā māka alanui no ke alakaʻi ʻana i nā kaʻa a me ka hoʻonui ʻana i ka palekana alanui. ʻOiai hoʻohana ʻia nā huaʻōlelo "pena" a me ka "coating" i kekahi manawa, pili lākou i nā ʻano papa like ʻole me nā waiwai a me nā noi.
ʻO ka pena kaha alanui ka mea maʻamau he mea wai e maloʻo e hana i kahi kiʻiʻoniʻoni lahilahi. ʻO nā ʻano mea maʻamau he acrylics ma muli o ka wai a me nā alkyds solvent-based. ʻIke ʻia kēia mau pena no ko lākou manawa maloʻo wikiwiki, maʻalahi o ka noi ʻana, a me ke kumu kūʻai haʻahaʻa. Eia nō naʻe, hāʻawi lākou i kahi ola lawelawe pōkole, koi pinepine i ka noi hou ʻana i kēlā me kēia 1-2 mau makahiki ma muli o ke kāʻei ʻana mai ke kaʻa a me ka wā.
ʻO ka uhi hōʻailona alanui, ma ka ʻaoʻao ʻē aʻe, he huaʻōlelo umbrella no nā mea ʻoi aku ka lōʻihi. ʻO kēia mau mea me nā thermoplastics, nā mea i hoʻohana ʻia i ke anuanu (CAP), a me nā epoxies. No ka laʻana, hoʻohana ʻia nā Thermoplastics i ka wela (180-220°C) a hana i kahi papa mānoanoa a paʻa i ka wā hoʻomaha. Ua ʻike ʻia lākou no ka lōʻihi loa, ʻo 3-6 mau makahiki, a me ka retroreflectivity kiʻekiʻe ma muli o nā peʻa aniani i hoʻokomo ʻia, akā makemake lākou i nā mea hana kūikawā a hōʻike i kahi hoʻopukapuka mua kiʻekiʻe.
ʻO ke koho ma waena o ka pena a me ka uhi ʻana ma muli o nā kumu he nui. He kūpono ka pena no nā alanui kūlanakauhale, nā wahi kaʻa kaʻa, a me nā wahi kaʻa kaʻa haʻahaʻa kahi i hana mua ʻia ai ke kumukūʻai a me ka noi wikiwiki. ʻOi aku ka maikaʻi o nā ʻaʻahu kiʻekiʻe e like me nā thermoplastics no nā wahi kaʻa nui e like me nā alaloa a me nā ʻāpana, kahi mea koʻikoʻi no ka palekana.
I ka hōʻuluʻulu ʻana, ʻo ka pena kaha alanui he ʻano uhi kikoʻī i waiwai ʻia no kona ʻoihana a me ka maʻalahi, ʻoiai ʻo ka uhi ʻana o ke alanui e hoʻopuni ana i kahi ākea ākea o nā mea hana kiʻekiʻe a paʻa i hoʻolālā ʻia no ka hoʻohana lōʻihi ma nā alanui koi.
