Hiki i kekahi o ʻoukou ke hoʻohana i ke kaʻina hana lapaʻau wela wela, me he mea lā ua kahiko ʻia.ʻO ka uhi Dacromet kahi koho maikaʻi loa no ʻoe.ʻO nā ʻāpana kila a me nā hao e pono ai ka pale hou mai ka paʻakai ʻino ʻia he galvanized wela a i uhi ʻia ʻo Dacromet, ʻo ia nā ʻāpana Zinc.He inoa inoa ʻo Dacromet me kahi noi "zinc flake" i hoʻopaʻa ʻia.I kekahi manawa ua maʻalahi kēia inoa inoa e weheweheka uhi ʻana o ka zinc galvanized.Ma kēia ʻatikala, e wehewehe ʻia nā pōmaikaʻi o ke kaʻina hana uhi Dacromet e kōkua iā ʻoe e hoʻomaopopo maikaʻi.
Nā ʻokoʻa ma waena o Dacromet a me ke kaʻina hana galvanizing wela
Hoʻomoʻa ʻia ke kaʻina hana Dacromet ma kahi o 500F ma hope o ka noi ʻana, akā hana ʻia ke kaʻina hana galvanizing wela ma ka mahana o ka zinc hehee (780F) a i ʻole ka wela.Me ka mea hope, hiki iā ʻoe ke hoʻomaha i ke kaumaha o nā ʻāpana i pilikia paha iā ʻoe.
Ua lōʻihi ka wā lōʻihi a kaulana loa ka galvanizing wela.Hoʻokomo ʻia ka ʻāpana i loko o ka hui ʻana o ka zinc i hoʻoheheʻe ʻia ma kahi mahana o 460 ℃ e hana me ke kalapona kalapona e hana i ka zinc carbonate.
Loaʻa i ka Dacromet ke kūpaʻa wela maikaʻi;e hōʻike ana ka uhi galvanized maʻamau i nā māwae liʻiliʻi ma kahi kiʻekiʻe ma mua o 70 ℃, a e hoʻemi nui ʻia ka discolor a me kona kūpaʻa corrosion ma 200-300 ℃.
ʻO ka mahana ho'ōla o Dacromet anti-corrosion film he 300 ℃, no laila ʻaʻole e hoʻololi ke ʻano o ka metala i kona ʻano a hiki ke hoʻomau i kona ʻāʻī ʻana i ka wela wela ʻoiai ke kau ʻia i ka wela kiʻekiʻe no ka manawa lōʻihi.
ʻAʻole like me ka uhi wela wela,ʻO ka uhi ʻana o Dacrometʻaʻohe hydrogen embrittlement.Hiki i nā ʻāpana metala i mālama ʻia me Dacromet ke hana i ke kiʻiʻoniʻoni ʻoiai i loko o nā lua maikaʻi loa a me ka uhi anti-corrosion me ka permeability hohonu.Hoʻopili ʻia ka uhi ʻokoʻa i loko o nā ʻāpana tubular a loaʻa ka permeability maikaʻi no ka mea hiki ke hoʻoheheʻe ʻia ka wai Dacromet.
ʻO nā pono o ka uhi ʻana o Dacromet
1. ʻOi aku ka pale ʻana i ka corrosion
ʻO ka mānoanoa o ka papa kiʻiʻoniʻoni Dacromet he 4-8μm wale nō, akā ʻoi aku kona hopena anti-rust ma mua o 7-10 mau manawa o ka electro-galvanizing kuʻuna, hot-dip galvanizing a i ʻole ka uhi ʻana.ʻAʻole e ʻike ʻia ka ʻulaʻula ma nā ʻāpana maʻamau a me nā hui paipu i mālama ʻia me ke kaʻina hana Dacromet e ka hoʻāʻo ʻana i ka paʻakai paʻakai ma mua o 1,200h.
2. ʻAʻohe hydrogen embrittlement
Hoʻoholo ke kaʻina hana lapaʻau ʻo Dacromet ʻaʻohe hydrogen embrittlement ma Dacromet, no laila kūpono ʻo Dacromet no ka uhi ʻana i nā ʻāpana koʻikoʻi.
3. Kūleʻa wela kiʻekiʻe
Hiki i ka Dacromet ke pale aku i ka corrosion wela kiʻekiʻe, a hiki i ka wela wela ke piʻi aku ma mua o 300 ℃.Eia nō naʻe, e hana ʻia ka ʻili ʻana a i ʻole ka ʻoki ʻana i ke kaʻina hana galvanizing kuʻuna ke piʻi ka mahana i 100 ℃.
4. Adhesion maikaʻi a me ka recoatability
ʻO ka uhi ʻana o DacrometLoaʻa ka pili pono me ka substrate metala a me nā mea hoʻonaninani ʻē aʻe.He mea maʻalahi i nā ʻāpana i mālama ʻia ke kāpīpī i ka kala, a ʻoi aku ka ikaika o ka hoʻopili ʻana me ka uhi kūlohelohe ma mua o ke kiʻi phosphate.
5. Hiki maikaʻi loa
Ma muli o ka hopena pale electrostatic, paʻakikī ke electroplate i nā lua hohonu a me nā ʻāpana o ka mea hana a me ka paia o loko o ka paipu, no laila ʻaʻole hiki ke pale ʻia nā ʻāpana o luna o ka mea hana e ka electroplating.Hiki iā Dacromet ke komo i kēia mau ʻāpana o ka mea hana e hana i kahi uhi Dacromet.
6. ʻAʻohe haumia a me nā pōʻino lehulehu
ʻAʻole hana ʻo Dacromet i ka wai ʻōpala a i ʻole nā gasana ʻōpala e hoʻohaumia i ke kaiapuni i ka wā o ke kaʻina holoʻokoʻa o ka hana ʻana, ka hana ʻana a me ka uhi ʻana i nā mea hana, no laila ʻaʻohe pono o ka mālama ʻana i ʻekolu, no laila e hōʻemi ana i ke kumukūʻai lapaʻau.
7. ʻOi aku ka lōʻihi o nā hola paʻakai
ʻOi aku ma mua o 500 mau hola paʻakai i hoʻohālikelike ʻia me ka lōʻihi o 240 mau hola maka uhi ʻana o ka zinc galvanized.ʻO ka paʻakai paʻakai kahi hoʻāʻo maʻamau o ka ʻoihana kahi i waiho ʻia ai nā ʻāpana i kahi mahana i hoʻomalu ʻia o 35 ℃ a kau ʻia i kahi hoʻoheheʻe mau o ka solution sodium-chloride.Hoʻopaʻa ʻia ka hoʻāʻo ʻana i ka paʻakai i nā hola a hoʻopau ʻia ke ʻike ʻia ka ʻulaʻula ma nā ʻāpana.
ʻEhiku mau pōmaikaʻi o Junhe Dacromet coating solution
Hoʻokumu ʻia me nā mea waiwai kiʻekiʻe, ʻo Junhe Dacromet coating solution kahi mea ʻē aʻe i ka electro-galvanizing a me ka hot-dip galvanizing no ka pale ʻana i ka corrosion.Hiki i nā huahana o Junhe ke hoʻokō i nā koi o nā mea kūʻai aku ma nā pae like ʻole o ka hana.
1. Pono ke kumu kūʻai.ʻOi aku ka haʻahaʻa o ke kumukūʻai holoʻokoʻa o ka hoʻonā ʻana o Junhe.
2. Hoʻomaha maikaʻi loa.ʻAʻole i maʻalahi ka hoʻoponopono ʻana ma muli o ka hoʻokuʻu maikaʻi ʻana, a hiki ke hoʻopuʻi ʻia ka hopena pahu no ka manawa lōʻihi, ʻoi aku ka maʻalahi o nā mea kūʻai aku me ka lawa ʻole a i ʻole ka hana intermittent.
3. ʻO ka pae maikaʻi.ʻAʻole maʻalahi ka ʻili i ka sagging a me ka ʻili ʻalani.
4. Hoʻopili maikaʻi.ʻAʻole hiki ke ʻili a ʻoi aku ka ikaika o ka pale ʻana i ka corrosion.
5. Hoʻopuehu maikaʻi.Ma muli o ka hoʻopuehu maikaʻi ʻana, ʻano like ka ʻili a me ka ʻāpana ʻole ma hope o ka uhi ʻana o ka ʻili.
6. Ka paakiki ili maikai.ʻAʻole maʻalahi ka ʻeha i ka wā o ka waiho ʻana a me ka lawe ʻana.
7. ʻO ke kūpaʻa paʻakai maikaʻi.
