Koj paub tias lub sijhawm nyob ntawm cov kab lag hlau siv rau lub neej feem ntau yog dab tsi?

Yog kom ua rau zoo dua lub neej ntawm cov hlau siv, cov hlau siv tshwj xeeb (hlau dawb) yog siv tam sim no. Cov hlau siv tam sim no muaj ob hom yog hot dip galvanized thiab electric galvanized. Lub zog siv tam sim no yog ntau thiab lub nplai ntawm electric galvanizing yog tsawg, yog li muaj cov hlau siv tam sim no. Nyob rau hauj lwm ntawm kev pab cuam, tus neeg yuav cov hlau siv tam sim no kuj ua tau ntau.

Cov khoom hlau siv tam sim no tau muaj nyob rau hauv ob peb qhov chaw, qhov tseem ceeb ntawm hot-dip galvanized yog tias lub neej ntawm cov hlau siv yog ntev. Nws tau siv rau hauv cov chaw loj loj xws li lub tsev hluav taws, cov tsev hluav taws saum npoo, kev ua haujlwm, kev saib xyuas kev lag luam, lub tsev hluav taws saum toj, cov khoom siv hauv av, cov khoom siv hlau rau kev tsim tsev, cov khoom siv rau cov tsev kho vajtswv, thiab lwm yam.

Kev ua plating zoo li no yog ua kom pa tshuab nrog lub tshuab hluav taws xob, kom tiv thaiv cov hluav taws xob uas nyob rau hauv nruab nrog cov hluav taws xob, tom qab ntawv, hloov mus rau qhov chaw ua haujlwm nrog cov duab nrog ammonium chloride lossis zinc chloride lossis ammonium chloride thiab zinc chloride ua ke, tom qab ntawv cia nrog cov duab hluav taws xob. Kev ua plating zoo li no muaj peev xwm zoo li cov nta khoom zoo, zoo li qhov zoo thiab lub sijhawm ntev. Ntau qhov chaw ua siab hauv lub ntiaj teb no ua haujlwm nrog cov nta khoom zoo li no.

Lub sijhawm zoo li no ntawm cov pa tshuab hluav taws xob zoo li no nyob rau hauv qhov chaw txawv txawv zoo li no: 13 xyoo nyob rau hauv qhov chaw ua siab, 50 xyoo nyob rau hauv dej, 104 xyoo nyob rau hauv qhov chaw nroog, thiab 30 xyoo nyob rau hauv qhov chaw ua siab.
