Cov yeeb nkab kub-dip galvanized

Cov hlau uas yaj yuav ua rau cov hlau matrix ua rau muaj ib txheej hlau sib xyaw, yog li ntawd cov matrix thiab cov txheej txheej yuav sib xyaw ua ke. Kev kub dip galvanizing yog thawj zaug pickling cov yeeb nkab hlau, txhawm rau tshem tawm cov hlau oxide ntawm qhov chaw ntawm cov yeeb nkab hlau, tom qab pickling, los ntawm ammonium chloride lossis zinc chloride aqueous solution lossis ammonium chloride thiab zinc chloride sib xyaw aqueous solution tank rau kev ntxuav, thiab tom qab ntawd mus rau hauv lub tank kub dip plating. Kev kub dip galvanizing muaj qhov zoo ntawm kev sib xws txheej, muaj zog lo thiab lub neej ntev. Feem ntau ntawm cov txheej txheem hauv sab qaum teb txais yuav cov txheej txheem zinc replenishment ntawm galvanized siv ncaj qha coil yeeb nkab.

Cov yeeb nkab galvanized txias

Cov yeeb nkab galvanized txias yog cov yeeb nkab galvanized hluav taws xob, cov yeeb nkab galvanized me me heev, tsuas yog 10-50g / m2, nws tus kheej tiv taus corrosion txawv ntawm cov yeeb nkab galvanized kub. Cov chaw tsim khoom yeeb nkab galvanized ib txwm, txhawm rau kom ntseeg tau tias zoo, feem ntau tsis siv hluav taws xob galvanizing (txias plating). Tsuas yog cov lag luam me me uas muaj cov khoom siv qub siv hluav taws xob galvanizing, tau kawg, lawv cov nqi pheej yig heev. Yav tom ntej, cov yeeb nkab galvanized txias tsis raug tso cai siv ua cov yeeb nkab dej thiab roj.

Cov yeeb nkab hlau kub-dip galvanized

Muaj cov tshuaj lom neeg thiab lub cev sib xyaw ua ke ntawm cov kav hlau thiab lub dab dej uas yaj ua ke los tsim ib txheej zinc-hlau sib xyaw uas ruaj khov thiab tiv taus xeb. Cov txheej hlau sib xyaw ua ke nrog cov txheej zinc ntshiab thiab cov kav hlau. Yog li ntawd, nws txoj kev tiv taus xeb muaj zog heev.

Tom qab kev tsim cov yeeb nkab kub galvanized steel hauv xyoo 1960 txog 1970, cov khoom zoo tau zoo dua qub, xyoo 1981 txog 1989 tau txais txiaj ntsig los ntawm Ministry of metallurgy of high-quality products thiab lub teb chaws silver award, kev tsim khoom kuj tau nce ntxiv rau ntau xyoo, xyoo 1993 muaj ntau tshaj 400,000 tons, xyoo 1999 muaj ntau tshaj 600,000 tons, thiab xa tawm mus rau Southeast Asia, Africa, Tebchaws Meskas, Nyiv Pooj, Lub Tebchaws Yelemees thiab thaj chaw. Cov yeeb nkab kub-dip galvanized feem ntau yog siv ua cov yeeb nkab dej thiab cov yeeb nkab roj, thiab cov lus qhia dav dav yog +12.5 ~ + 102 hli. Tom qab xyoo 1990, vim yog lub xeev txoj kev saib xyuas rau kev tiv thaiv ib puag ncig, kev tswj hwm cov lag luam muaj kuab paug siab tau dhau los ua qhov nruj dua, "peb qhov pov tseg" tsim los ntawm kev tsim cov kav dej kub-dip galvanized nyuaj rau daws, ua ke nrog kev txhim kho sai ntawm cov kav dej stainless hlau welded, cov kav dej PVC thiab cov kav dej sib xyaw, nrog rau lub xeev los txhawb kev siv cov khoom siv tshuaj lom neeg hauv tsev, kev siv cov kav dej hlau galvanized raug txwv, ua rau kev txhim kho ntawm cov kav dej kub-dip galvanized welded tau raug cuam tshuam loj heev Beam thiab txwv, cov kav dej kub-dip galvanized welded tom qab tsim qeeb qeeb.

Cov yeeb nkab hlau galvanized txias

Cov txheej zinc yog ib txheej hluav taws xob, thiab cov txheej zinc yog txheej ywj pheej nrog cov yeeb nkab hlau matrix. Cov txheej zinc yog nyias, thiab cov txheej zinc tsuas yog txuas rau cov yeeb nkab hlau matrix thiab yooj yim poob tawm. Yog li ntawd, nws txoj kev tiv thaiv corrosion yog pluag. Hauv cov tsev nyob tshiab, nws raug txwv tsis pub siv cov yeeb nkab hlau galvanized txias ua cov yeeb nkab xa dej.
