ʻO nā pono o ka Epoxy Polyester Hybrids Ka Waihona Powder

Ua ʻike ʻia nā ʻāpana pauka epoxy e pili ana i ka ʻenehana hou he epoxy-polyester "hybrids" a i ʻole "multipolymer" ʻōnaehana. Hiki ke noʻonoʻo ʻia kēia pūʻulu o ka pauka he ʻāpana wale nō o ka ʻohana epoxy, koe wale nō ka hapa nui o ka polyester i hoʻohana ʻia (ʻoi aku ka nui ma mua o ka hapalua o ka resin) e alakaʻi hewa ana kēlā hoʻohālikelike.
ʻOi aku ka pili o nā waiwai o kēia mau uhi hybrid i nā epoxies ma mua o nā polyesters, me nā ʻokoʻa ʻē aʻe. Hōʻike lākou i ka maʻalahi like ʻole i ka hopena a me ke kūpaʻa kūlou, akā e hana i nā kiʻi ʻoniʻoni liʻiliʻi. ʻO ko lākou kūpaʻa corrosion e hoʻohālikelike ʻia me nā epoxies i nā manawa he nui, akā ʻo ko lākou kūʻē ʻana i nā solvents a me ka alkali he gene.ralhaʻahaʻa loa i nā epoxies maʻemaʻe.

ʻO kekahi mea maikaʻi o kēia mau hybrids, ma muli o ka hopena o ka ʻāpana polyester, ʻo ia ke kūpaʻa kiʻekiʻe i ka melemele ma luna o ka kuke ʻana i ka umu lapaʻau. ʻO kēia ka unuhi ʻana i kekahi hoʻomaikaʻi ʻana i ke kūpaʻa ʻana i ka melemele kukui ultraviolet. E hoʻomaka ana kēia mau ʻōnaehana e paʻakai e like me ka epoxy akā, ma hope o ka hoʻomaʻamaʻa mua ʻana, ʻoi aku ka lohi o ka pōʻino a ʻoi aku ka paʻakikī o ka wehe ʻana ma mua o nā pauka epoxy i hoʻololi ʻole ʻia.

ʻO kekahi pono ʻē aʻe o ka epoxy/polyester powder coatings ʻo kā lākou mau hiʻohiʻona electrostatic spray maikaʻi. Hiki ke hoʻohana ʻia me ka maikaʻi o ka hoʻoili ʻana a hōʻike i ke komo maikaʻi ʻana i nā kihi a me nā recesses. Ua helu ʻia nā noi no kahi epoxy polyester hybrid ma ke Kiʻi 2-3; helu ʻia nā waiwai maʻamau ma ka Figure 2-4.
