ʻO ka Petroleum resin kahi ʻano epoxy resin me ke kaumaha molekala haʻahaʻa. ʻOi aku ka haʻahaʻa o ka paona molekala ma mua o 2000. Loaʻa iā ia ka ductility thermal a hiki ke hoʻoheheʻe i nā mea hoʻoheheʻe, ʻoi aku ka nui o nā mea hoʻoheheʻe ʻaila ʻaila. He kūpono maikaʻi me nā mea resin ʻē aʻe. Loaʻa iā ia ke kūpaʻa abrasion kiʻekiʻe a me ke kūpaʻa ʻelemakule.
Hoʻohana ʻia ʻo Calcium Aluminum Alloy ma ke ʻano he mea hoʻohaʻahaʻa a me ka mea hoʻohui i ka ʻoihana metallurgical e pāʻani i ka desulfurization, deoxidation a me nā hoʻomaʻemaʻe ʻē aʻe.
ʻO ke ʻano o ke kaʻina hana kaʻa pōhaku ʻālohilohi, ʻo ia ka hoʻohui ʻana i ka hōʻiliʻili pōhaku ʻālohilohi me ka ʻāpana kala, ka mālama ʻana i ka ʻili me ka retarder a holoi i ke ʻano "pohaku holoi" hou o ka hui a me ke kino kukui.
ʻO ka hoʻāʻo ʻana me ka pena kalaiwa maʻamau ʻAmelika
ʻO ka HF Series Reflective glass beads ka mea nui no ka uhi ʻana o ke kaha alanui i hoʻohana nui ʻia no ka māka alanui. Hiki i nā ʻeke aniani no ka māka alanui ke hoʻomaikaʻi i ka hana retro-reflective o ka uhi ʻana o ke alanui a hoʻonui i ka palekana no ka hoʻokele pō.
