Galvanized Steel Pipe
Kambani yedu inoita seamless simbi pombi ekisipotigalvanized pipe, Seamless Galvanized Pipe, SMLS galvanized pombi, WEDED galvanized pipe.
Ndeupi musiyano uripo pakati pekupisa galvaninzed nechando galvanized?
Kupisa-dip galvanizing uye kutonhora kwakakurudzira musiyano:
1. Galvanizing, inozivikanwawo seanopisa dip yakakurudzira, ndiye ingot yakanyungudutswa pakupisa kwepamusoro, nhamba yezvinyorwa zvekuwedzera panzvimbo, zvino yakanyikwa marata ekugadzirwa kwesimbi, chikamu chesimbi pamucheka we zingi. Zvakanakira zvekupisa-dip galvanizing corrosion yekugona kwake, kunamatira uye kuoma kwe zinc coating zviri nani.
"Cold plated" kana "plating", kureva kuti zinc munyu solution ne electrolysis, kusvika pakuputira pamusoro pekuputira, kazhinji haina kudziyisa, shoma shoma ye zinc, nzvimbo yakanyorova iri nyore kudonha.
2. Dip inopisa yakabatiswa (galvanizing)
Kupisa-dip galvanizing kurapwa kwemakemikari, ndiyo electrochemical reaction.
Cold galvanizing ndiyo kero yemuviri, ingo bhurasha nzvimbo ye zinc, iyo zinc layer iri nyore kudonha. Kuvaka mukushandiswa kwekupisa dip galvanizing.
Inoenderera ichipisa dip galvanizing process: simbi → kudziyisa → kutonhora kusvika kune tembiricha yakabatiswa marata → kutonhora →
Cold galvanized zinc ingori 10-50g/m2, yayo pachayo corrosion resistance pane kupisa dip galvanized a lot of difference. Yakavharidzirwa nemutengo wakaderera.
Kupisa dip galvanized simbi muviri inopisa dip galvanized surface pasi pemamiriro ekunamatira kwayo kwakasimba, haisi nyore kudonha, kunyangwe paine dip inopisa.galvanized pipecorrosion phenomenon, asi munguva yakareba kwazvo yekusangana nehunyanzvi, hutano zvinodiwa.
3. Misiyano yehunyanzvi
Chekutanga, ndiwo musiyano uripo pakati pemaitiro: inopisa-dip galvanizing ndiyo workpiece degreasing, pickling, dipping, kuomesa mvura kunyudzwa mune yakanyungudutswa zinc imwe nguva yenguva, inogona kusimudzwa.
Iyo inozivikanwawo se electro-galvanized cold galvanizing, ndeye kushandisa electrolysis zvishandiso basa chidimbu kuburikidza ne degreasing, pickling ingredients post kupinda zinc munyu mhinduro, uye batanidza anode electrolysis midziyo; panzvimbo pamativi e zinc plate yakabatana ne electrolysis midziyo yakanaka, simba pa, kushandiswa kwezvino kubva pa cathode kusvika kune anode yekutungamira mafambiro eiyo workpiece ichaiswa muchikamu chezingi.
Zinc yakapedza mutsauko: hapana inotonhora yakanyungudutswa inopisa-dip galvanizing yakapfava inopenya kutaridzika, asi ukobvu hwezinc yekuputira yeinotonhora inonamira zvinhu zvekupisa-dip galvanizing kakati wandei. Galvanized corrosion resistance iri zvakare kakawanda.
Overview
Application
Iyo Inonyanya Kushandiswa kune simba uye kumanikidza zvikamu, uye kune zvakajairika chinangwa chiputi, mvura, gasi uye mhepo pombi.
