Polyaspartic Coating Technology
Hoʻokumu ʻia ka kemika ma ka hopena o kahi polyisocyanate aliphatic a me kahi ester polyaspartic, ʻo ia ka diamine aliphatic. Ua hoʻohana mua ʻia kēia ʻenehana i nā mea hoʻoheheʻe polyurethane solvent-borne coating maʻamau no ka mea ʻo nā polyaspartic esters he mea hoʻoheheʻe hoʻoheheʻe maikaʻi loa no nā uhi polyurethane paʻa kiʻekiʻe.
ʻO nā mea hou aʻe i hoʻomohala ʻia i ka ʻenehana uhi polyaspartic i hoʻopaʻa ʻia i ka loaʻa ʻana o nā uhi VOC haʻahaʻa a kokoke paha i kahi ester polyaspartic ka mea nui o ka co-reactant no ka pane ʻana me kahi polyisocyanate. ʻO ka hana kūʻokoʻa a hiki ke hoʻololi ʻia o nā esters polyaspartic e hiki ai i ka hoʻolālā ʻana i nā uhi hoʻōla wikiwiki i kūpono i nā pono o ka noi. ʻO ka hiʻohiʻona hoʻōla wikiwiki o kēia mau uhi hiki ke hāʻawi i ka hoʻomaikaʻi ʻana i ka huahana nui, mālama kālā, me ka hoʻōla ʻana i ke kūkulu kiʻekiʻe, haʻahaʻa haʻahaʻa, a me ka abrasion a me ka pale ʻana.
Ua kaulana loa ka inoa polyaspartics i waena o nā mea hoʻokumu i ka ʻoihana ma muli o ka pono e hoʻokaʻawale iā ia mai polyureas a me polyurethanes. Ma ka wehewehe ʻana, ʻo ka polyaspartic he polyurea aliphatic no ka mea ʻo ia ka hopena o kahi polyisocyanate aliphatic me kahi ester polyaspartic - he diamine aliphatic. Eia nō naʻe, ʻokoʻa loa nā uhi polyaspartic i ka noi a me ka uhi ʻana i nā waiwai hana mai nā polyureas maʻamau. No ka laʻana, hiki i ka polyaspartics ke hoʻoponopono i ka wikiwiki o ka hopena a me ka ho'ōla, no laila, hiki ke hoʻololi i ka potlife o ka hui ʻelua ʻāpana mai ʻelima mau minuke a ʻelua mau hola. ʻOiai ʻo ka hoʻohana ʻana i ka plu i loko o nā ʻenehana noi sprayral nā mea hoʻoheheʻe ʻāpana, hiki ke hoʻohana ʻia nā noi he nui me nā sprayers maʻamau, e hoʻemi i ka paʻakikī o ka noi a emi ʻole i ka hewa.
ʻOi aku ka pili o ka ʻenehana Polyaspartic i kāna mau noi a me nā hiʻohiʻona hana i ka 2-component aliphatic polyurethane coatings. Hoʻohana pinepine ʻia e like me ka topcoat ma muli o kona ʻano melemele ʻole. Akā, ma ʻaneʻi hoʻi, aia nā ʻokoʻa koʻikoʻi. Hiki ke hoʻopili ʻia nā pale polyaspartic i nā mea paʻa kiʻekiʻe loa (70-100% solids) a hoʻohana ʻia i nā hale kiʻiʻoniʻoni kiʻekiʻe (a hiki i 15 mils WFT i loko o kahi kapa hoʻokahi) ma mua o nā polyurethanes aliphatic ʻelua. No ka mea ʻoi aku ka wikiwiki o ka maloʻo ʻana o nā polyaspartics ma mua o nā polyurethanes aliphatic maʻamau, hoʻohana pinepine ʻia lākou i nā noi kahi e hoʻōla wikiwiki ai ʻo ia ka hoʻomaikaʻi ʻana i ka huahana i ka hana pena.
