Chloride Free MgO Board Guide

What Is a Chloride-Free MgO Board

A chloride-free MgO board is a special kind of magnesium oxide board. It is made for new building projects. These boards use magnesium sulfate instead of magnesium chloride. This change makes the boards safer and better for the environment. The chloride free mgo board guide points out some important differences:

  • Magnesium sulfate is used instead of magnesium chloride in these boards.
  • The new mix helps stop rust, even in wet or salty places.
  • Chloride-free boards do not have the risk of rust from chloride ions.
  • Using magnesium sulfate makes the boards more stable and less likely to react badly over time.
  • These boards last longer and do not need as much fixing.
  • They are better for the planet and are more eco-friendly than old boards.

Builders use these boards for many things like walls, ceilings, and floors. The boards are good for building because they do not burn easily and do not get damaged by water. They also help builders make greener and safer buildings.

Why Chloride-Free Matters

Chloride-free magnesium oxide boards have many clear benefits for building. The chloride free mgo board guide explains how these boards are better than older boards in many ways.

Performance Aspect

Supporting Evidence and Benefits

Moisture Resistance

Chloride-free boards do not soak up water, are 72.2% better at staying dry, and do not swell or bend.

Durability

They are stronger than drywall, keep their shape in bad weather, and can handle sun, frost, and heavy rain.

Mold and Mildew Resistance

The boards are made from materials that do not let mold or mildew grow, so the air inside stays cleaner and the boards last longer.

Corrosion Resistance

No chloride means metal parts will not rust, and there is a 20-year promise against rust and water damage.

Fire Resistance

These boards meet safety rules, can take heat up to 1200°F, and do not make toxic smoke if there is a fire.

Structural Integrity

They are strong enough for floors, roofs, and ceilings, and they do not bend easily.

Environmental Impact

The boards are made using less energy, can be recycled, do not have harmful chemicals, and help with green building.

Compliance with Standards

They meet strict building rules, so repairs cost less and buildings are worth more.

Tests show that chloride-free boards do not have water problems or rust like old boards do. Using magnesium sulfate and things like GGBS makes the boards last longer and work well in tough places. These boards help make buildings safer and stronger with fewer repairs. Builders who care about the environment and want safe buildings pick these boards for their work.
