Cov Yeeb Nkab Hlau Galvanized: Loj, Hom thiab Nqe - Royal Group

Cov yeeb nkab hlau galvanizedyog ib lub yeeb nkab hlau uas tau welded nrog lub kub-dip lossis electroplated zinc txheej. Galvanizing ua rau cov yeeb nkab hlau tiv taus corrosion thiab ntev nws lub neej kev pabcuam. Galvanized yeeb nkab muaj ntau yam kev siv. Dhau li ntawm kev siv ua kab yeeb nkab rau cov kua dej qis xws li dej, roj, thiab roj, nws kuj siv rau hauv kev lag luam roj av, tshwj xeeb tshaj yog rau cov yeeb nkab roj thiab cov kav dej hauv cov roj av hauv hiav txwv; rau cov cua sov roj, condenser txias, thiab thee distillation thiab ntxuav cov roj pauv hauv cov khoom siv tshuaj coking; thiab rau pier piles thiab cov thav duab txhawb nqa hauv cov qhov av hauv av.

Hom Txoj Cai Txheej Txheem Cov Nta Tseem Ceeb Lub Neej Pabcuam Cov Xwm Txheej ntawm Daim Ntawv Thov
Kub Dip Galvanized Steel Yeeb Nkab Muab cov yeeb nkab hlau tso rau hauv cov kua zinc uas yaj (kwv yees li 440-460 ℃); ib txheej tiv thaiv ob txheej ("txheej zinc-hlau alloy + txheej zinc ntshiab") tsim rau ntawm qhov chaw ntawm cov yeeb nkab los ntawm kev sib xyaw tshuaj ntawm cov yeeb nkab thiab zinc. 1. Txheej zinc tuab (feem ntau yog 50-100μm), muaj zog nplaum, tsis yooj yim tev tawm;
2. Kev tiv thaiv xeb zoo heev, tiv taus cov kua qaub, alkali thiab cov chaw nyob sab nraum zoov;
3. Tus nqi ua haujlwm siab dua, xim nyiaj-grey zoo li muaj cov qauv ntxhib me ntsis.		 15-30 xyoo Cov haujlwm sab nraum zoov (piv txwv li, cov ncej teeb ntawm txoj kev, cov ntaiv tiv thaiv), cov dej xa tawm hauv nroog / dej ntws, cov kav dej tua hluav taws, cov kav dej siab siab hauv kev lag luam, cov kav dej roj.
Electro Galvanized Steel Yeeb Nkab Cov zinc ions raug tso rau ntawm qhov chaw ntawm cov yeeb nkab hlau los ntawm electrolysis los tsim cov txheej zinc ntshiab (tsis muaj txheej alloy). 1. Txheej zinc nyias nyias (feem ntau yog 5-20μm), tsis muaj zog nplaum, yooj yim hnav thiab tev tawm;
2. Tsis kam xeb, tsuas yog haum rau qhov chaw qhuav, tsis xeb hauv tsev;
3. Tus nqi qis, ci ntsa iab thiab du.		 2-5 xyoos Cov kav dej sab hauv tsev uas muaj qhov siab qis (piv txwv li, kev muab dej ib ntus, cov kav dej kho kom zoo nkauj ib ntus), cov khoom siv rooj tog (tsis muaj qhov hnyav), cov khoom dai kom zoo nkauj sab hauv tsev.

Tus nqi ntawm cov kav hlau galvanized yog dab tsi?

Tus nqi ntawm cov yeeb nkab hlau galvanized tsis ruaj khov thiab hloov pauv ntau vim muaj ntau yam, yog li nws tsis yooj yim sua kom muab tus nqi sib npaug.

Thaum koj yuav khoom, peb xav kom koj nug txog koj cov kev xav tau tshwj xeeb (xws li txoj kab uas hla, phab ntsa tuab (piv txwv li, SCH40/SCH80), thiab qhov ntau thiab tsawg ntawm kev txiav txim—kev txiav txim ntau ntawm 100 meters lossis ntau dua feem ntau yuav tau txais luv nqi 5%-10%) kom tau txais tus nqi raug thiab tshiab.
