Indlela Yokukhetha Ubukhulu Be-Zinc Coating Obulungile Be-Galvanized Iron Wire Ngokusekelwe Ezingeni Lokugqwala Kwemvelo

Die Auswahl von verzinktem Eisen-Draht hängt davon ab, die Dicke der Zinkbeschichtung mit dem Korrosionsniveau der Umgebung abzustimmen. Die Zinkschicht schützt die Eisenbasis durch den Mechanismus der opfernden Anode und verzögert die Rostbildung. Im Allgemeinen gilt: Je korrosiver die Umgebung ist, desto dicker muss die Zinkbeschichtung sein.

In mild corrosion environments (e.g., dry indoors, rural atmospheres), a zinc coating of 20-50 g/m² (approx. 3-7μm) is sufficient. These environments have minimal corrosive factors, and the zinc layer primarily handles occasional humidity or weak acids/alkalis.

Ku moderate corrosion environments (e.g., urban atmospheres, light industrial areas, high-humidity zones), a higher level of protection is needed, with a zinc coating of 50-130 g/m² (7-18μm). Such environments often contain sulfur dioxide or salt particles, requiring a thicker zinc layer to extend service life.

In severe corrosion environments (e.g., coastal regions, industrial zones, chemical plants, or high-temperature/humidity areas), the zinc coating should be at least 130 g/m² (up to 250 g/m² or more). High concentrations of chlorides, strong acids, or alkalis accelerate zinc consumption, necessitating a thick coating for durable protection.

Ngaphezu kwalokho, umthwalo wezinto ezisebenzayo kufanele ucabangele: ukungqubuzana okuphezulu noma ukujolisa kudinga ukuhlanganiswa kahle kwezinc nokuphila. Bheka izindinganiso zamazwe omhlaba (isb., ISO 1461) noma xhumana nabahlinzeki, futhi usebenzise izivivinyo zokugqwala (isb., ukuhlolwa kokuphuma kwesawoti) ukuze ulinganise izidingo, uqinisekise ukuqina okuphezulu nokusebenza kahle kwezindleko kwe-wire ye-galvanized iron ezimweni ezithile.
