Puʻupuʻu a pūʻolo uea galvanized

ʻO ka pena ma ka papa galvanized, ʻo ka ikaika hoʻopaʻa ma waena o kekahi i kahi pilina nui me ka mahana bakena o ka pena, a ua uhi ʻia ka pena alkyd ma hope o ka galvanized, a ʻaʻole pilikia ka adhesion.Ma hope o ka galvanized e hana i ka pena amino, ʻaʻole maikaʻi loa ka hoʻopili ʻana i ka pena.Hana i ʻelua ʻaoʻao lalo ʻelua, maikaʻi ka hoʻopili ʻana, inā hoʻololi ʻia ka ʻaoʻao ʻelua i lalo i ʻelua ʻāpana ʻekolu, ʻo ia hoʻi, ʻoi aku ka pena, ʻoi aku ka ʻai ʻana i hoʻokahi manawa, ʻoi aku ka maikaʻi o ka hoʻāʻo ʻana i ka adhesion, maikaʻi ʻole e haehae i ka pena mai ka papa galvanized. .

ʻAʻole i hana i ka hoʻāʻo adhesion o ka pauka a i ʻole ka fluorocarbon spray ma luna o ka uea galvanized packaging, akā aia ʻelua mau helu no ka kuhikuhi: hoʻokahi, i ka hoʻopaʻa ʻia ʻana a i ʻole ka ea ea, hiki i nā volatiles non-metallic ke corrosion zinc coating;ʻO ka lua, ʻo ka zinc ma luna o 230 degere (c) e nawaliwali i ka metala kumu.Ma hope o ka pulupulu ʻana i ka pauka a me ka fluorocarbon spraying, pono ia e hoʻomoʻa i kahi mahana kiʻekiʻe a ma kahi wahi i hoʻopaʻa ʻia, e hoʻopōʻino wikiwiki ai i ka zinc, e hopena i ka ʻili ʻili ʻino e hoʻemi ai i ka adhesion o ka uhi, a hiki i ke kūlana brittle o ke kaula kila.
No ka mea ua hāʻawi ʻia ka uea galvanized i hoʻopaʻa ʻia me ka pre-tension, no laila ua loaʻa iā ia nā hiʻohiʻona maikaʻi loa o ka waiwai hoʻomaha haʻahaʻa, liʻiliʻi ke kaumaha o ke kaumaha, paʻa maikaʻi ma hope o ka hoʻouka ʻana, ʻaʻole maʻalahi i ka deformation, ʻaʻohe haʻihaʻi, elasticity ikaika, paʻakikī nā laina kila a me ka rebar. e hoohalike.Ka hoʻohana 'ana i ka holomua galvanized hoʻopau kaʻina hana, no laila, i ka hoʻohana 'ana i ka wela-hoi galvanized kila uea hana,ʻaʻole wale maikaʻi anti-corrosion hana, a nani lokomaikaʻi.Loaʻa i ka huahana nā hiʻohiʻona o ka ʻili maʻemaʻe, ka kikoʻī kiʻekiʻe kiʻekiʻe, ke kūlike maikaʻi o ka papa zinc a me ka paʻa paʻa.
