Hoʻomaʻamaʻa ʻia ka urethane ma luna o nā alahaka

wehewehe pōkole:

ʻO ka hoʻomaʻamaʻa ʻana o ka makū SWD polyurethane ʻoihana anticorrosion pale pale e lawe i hoʻokahi ʻāpana polyurethane resin polymer ma ke ʻano he mea maka.ʻO ka membrane kiʻiʻoniʻoni he paʻa, paʻa a elastic, hiki iā ia ke hoʻololi i ka deformation liʻiliʻi me ka ʻole o nā māwae mai ka haʻalulu a me nā loli o ka wā ma nā ʻano metala o nā ʻoihana ʻoihana.Hōʻalo ia i ke komo ʻana o ka ea, ka makū a me nā mea ʻino ʻē aʻe e lilo i anti rust o ke ʻano metala.ʻO ke kiʻi ʻoniʻoni he nui ka urea bond, biuret bond, urethane bond a me ka hydrogen bond e hana i nā waiwai kino maikaʻi a me ka hana anticorrosion.
