ʻO kahi pahu hoʻokahi i loaʻa ka zinc 96% i loko o kahi kiʻiʻoniʻoni maloʻo, kahi hana anti corrosion ʻē aʻe i ka wela wela
wehewehe
ʻO ZINDN kahi uhi galvanizing hoʻokahi i loaʻa he 96% ka lepo zinc i loko o ke kiʻi maloʻo a hāʻawi i nā pale cathodic a me nā pale pale o nā metala ferrous.
Hiki ke hoʻohana ʻia ʻaʻole he ʻōnaehana kūʻokoʻa wale nō e lilo i hana anticorrosion ʻē aʻe i ka galvanizing wela, akā ma ke ʻano he kumu mua i kahi ʻōnaehana duplex a i ʻole ʻekolu-layer ZINDN coating system.
Hiki ke hoʻohana ʻia ma ke kāpīpī ʻana, ka pulupulu ʻana a i ʻole ka ʻōwili ʻana ma luna o kahi substrate metala maʻemaʻe a ʻoʻoleʻa i kahi ākea o nā kūlana lewa.
Palekana Cathodic
I ka hoʻoheheʻe electrochemical, pili ka zinc metala a me ke kila me kekahi, a ʻo ka zinc me ka haʻahaʻa electrode hiki ke hoʻohana ʻia e like me ka anode, e nalowale mau ana i nā electrons a ua ʻino ʻia, ʻo ia hoʻi, ka anode mōhai;ʻoiai ke hoʻohana ʻia ke kila ponoʻī e like me ka cathode, ka mea e hoʻoili wale i nā electrons a ʻaʻole hoʻololi iā ia iho, no laila ua pale ʻia.
ʻOi aku ka nui o ka zinc ma ZINDN galvanizing layer ma luna o 95%, a ʻo ka maʻemaʻe o ka lepo zinc i hoʻohana ʻia e like me 99.995%.ʻOiai ua pōʻino iki ka papa galvanizing, ʻaʻole e pala ka hao ma lalo o ka papa zinc a hiki i ka pau ʻana o ka zinc, a i kēia manawa, hiki iā ia ke pale pono i ka laha ʻana o ka ʻōpala.
Pale pale
Hiki ke hoʻopaʻa paʻa ʻia ʻo ZINDN galvanizing layer me ka hala o ka manawa ma hope o ka noi ʻana, e hana ana i kahi pale paʻa, hoʻokaʻawale maikaʻi i nā kumu corrosion, a hoʻomaikaʻi nui i ka hiki ke anti-corrosion.
Hoʻohui ʻo ZINDN i nā hiʻohiʻona o ʻelua mau waiwai anti-corrosion i hoʻokahi, e uhaki ana i ka palena o ka lākiō puaʻa-kumu o nā uhi maʻamau, a loaʻa ka mana anti-corrosion maikaʻi loa.
95% ka lepo zinc i loko o ka ZINDN galvanizing layer maloʻo kiʻiʻoniʻoni, ʻoi aku ka kiʻekiʻe o ka nui o kēia manawa ma mua o ka uhi ʻana i ka zinc-waiwai.
Me ka hoʻonui ʻana o ka lepo zinc i loko o ka papa kiʻiʻoniʻoni maloʻo, e piʻi nui ka nui o ka corrosion o kēia manawa, a e piʻi nui hoʻi ka mana anti-corrosion electrochemical.
Nā pōmaikaʻi o ZINDN
Anti-corrosion lōʻihi
Active + Passive mau mea pale pale ʻelua, ka hoʻāʻo ʻana i ka paʻakai a hiki i 4500 mau hola, hiki ke maʻalahi i ka 25+ mau makahiki anticorrosion ola.
Pili ikaika
Ua hoʻopau piha ka ʻenehana fusion agent i ka pilikia adhesion o ka lepo zinc kiʻekiʻe (> 95%) i loko o kahi kiʻiʻoniʻoni maloʻo.Hiki i ka 4% ka hapa nui o ka fusion agent ke hoʻopaʻa paʻa i 24 mau manawa i kona kaumaha o ka lepo zinc a hoʻopaʻa iā ia me ka substrate a hoʻopili a hiki i 5Mpa-10Mpa.
Hoʻopili maikaʻi
Hiki ke hoʻohana ʻia ʻo ZINDN ma ke ʻano he papa hoʻokahi a i ʻole he ʻōnaehana ʻelua a ʻekolu paha me ka ZD sealer, topcoat, zinc silver, etc., e hoʻokō ai i nā pono o nā mea kūʻai aku no ka anticorrosion mau loa a me ka hoʻonani nani i nā kūlana kaiapuni.
ʻAʻohe māhā a hāʻule paha i hoʻohana ʻia i ka weld
Ua hoʻoholo ʻo ZINDN i ka bottleneck ʻoihana e haki maʻalahi ka papa galvanizing a hāʻule hāʻawi i ka weld, e hōʻoia i ka maikaʻi o ka noi.
Maʻalahi e hoʻopili
Hoʻokahi pūʻolo, hiki ke hoʻohana ʻia ma ke kāpī ʻana, ka pulupulu a i ʻole ka ʻōwili ʻana.ʻAʻole e pohō i lalo, ʻaʻole paʻa i ka pū, ʻaʻole paʻa i ka pamu, hoʻohana maʻalahi.
Kūʻai maikaʻi
Pilikino, kumu kūʻai haʻahaʻa, a maʻalahi hoʻi i ka hoʻopili ʻana i ka hoʻohālikelike ʻana i ka wela-luu a me ka hoʻoheheʻe wela.
ʻO nā wā lōʻihi ma waena o ka hoʻopā ʻana a me ka hoʻihoʻi hou ʻana, ke kumu kūʻai haʻahaʻa o ke ola kino anticorrosion i hoʻohālikelike ʻia me nā uhi waiwai epoxy zinc.
