ʻO ke kaula ʻano ʻili paipu (Elliptical)

ʻO ka ʻano kaula i hoʻopaʻa ʻia (Elliptical)

ʻO ka puʻupuʻu Elliptic finned ka mea hoʻoluʻu o ka puʻupuʻu hoʻoheheʻe ea pololei.Ma muli o ke ʻano o ka hoʻomaʻamaʻa ea pololei e hoʻohana ana i ke kaiapuni, no laila pono e loaʻa ka hana anti corrosive maikaʻi ma ka ʻili o ka ea cooler.I mea e hoʻomaikaʻi ai i ke ola lawelawe o ka mea hoʻomaʻamaʻa ea, hoʻohana ʻia ka zinc hot dip ma ka ʻili o Elliptic finned tube anti-corrosion.ʻO nā koi kūpono o ka Elliptic finned tube hot-dip zinc, ʻaʻole wale nā ​​​​koi maʻamau o nā ʻāpana zinc hot-dip e hoʻolei ana i ka maikaʻi o ka zinc, akā loaʻa pū kekahi i ka elliptical finned tube e like me nā koi kūikawā o ka mea hoʻoluʻu leaching maikaʻi zinc.ʻO nā hiʻohiʻona o ka wela wela zinc coating ʻo ia ka hopena pale ma ka ʻili o ka substrate o ke kila galvanized hot dip ʻoi aku ka maikaʻi ma mua o kahi pena a i ʻole ka papa plastic.I ka wā wela o ka zinc, ua laha ka zinc a me ka hao hao e hana i kahi papa hui metala i kapa ʻia ʻo layer alloy.ʻO ka papa Alloy he mau papa hana multilayer, a ʻo ka hui kemika ʻo Fe3Zn10 a i ʻole Fe5Zn21, FeZn7, FeZn13, a me nā mea ʻē aʻe.
