Both are building materials based on magnesium oxide (MgO), but they differ significantly in raw materials, performance, and applications.<\/p>\n<h2>1. Composition of Raw Materials<\/h2>\n<ul>\n<li><strong>Magnesium Chloride Boards<\/strong><br \/>\nThe main components are magnesium oxide (MgO) and magnesium chloride (MgCl\u2082). Magnesium oxide acts as a binding material, combined with reinforcing fibers and other fillers.<\/li>\n<li><strong>Magnesium Sulfate Boards<\/strong><br \/>\nThe main components are magnesium oxide (MgO) and magnesium sulfate (MgSO\u2084). Magnesium sulfate replaces magnesium chloride, making Magnesium Sulfate Boards more suitable for use in humid environments.<\/li>\n<\/ul>\n<h2>2. Water Resistance<\/h2>\n<ul>\n<li><strong>Magnesium Chloride Boards<\/strong><br \/>\nDue to the presence of magnesium chloride, these boards tend to deliquesce (absorb moisture) when exposed to water, leading to a decrease in strength. They are not suitable for prolonged exposure to moisture.<\/li>\n<li><strong>Magnesium Sulfate Boards<\/strong><br \/>\nThanks to the stability of magnesium sulfate, these boards have low water absorption and are more moisture-resistant, making them ideal for relatively humid environments.<\/li>\n<\/ul>\n<h2>3. Fire Resistance<\/h2>\n<ul>\n<li>Both materials exhibit excellent fire resistance, as magnesium-based materials have a high melting point, offering good fire protection.<\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"lazyload alignnone size-full wp-image-6348\" src=\"https:\/\/magnesium-oxide-board.com\/wp-content\/uploads\/2024\/11\/mgo-board-2.jpg\" data-orig-src=\"https:\/\/magnesium-oxide-board.com\/wp-content\/uploads\/2024\/11\/mgo-board-2.jpg\" alt=\"mgo board\" width=\"900\" height=\"600\" srcset=\"data:image\/svg+xml,%3Csvg%20xmlns%3D%27http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%27%20width%3D%27900%27%20height%3D%27600%27%20viewBox%3D%270%200%20900%20600%27%3E%3Crect%20width%3D%27900%27%20height%3D%27600%27%20fill-opacity%3D%220%22%2F%3E%3C%2Fsvg%3E\" data-srcset=\"https:\/\/magnesium-oxide-board.com\/wp-content\/uploads\/2024\/11\/mgo-board-2-200x133.jpg 200w, https:\/\/magnesium-oxide-board.com\/wp-content\/uploads\/2024\/11\/mgo-board-2-300x200.jpg 300w, https:\/\/magnesium-oxide-board.com\/wp-content\/uploads\/2024\/11\/mgo-board-2-400x267.jpg 400w, https:\/\/magnesium-oxide-board.com\/wp-content\/uploads\/2024\/11\/mgo-board-2-600x400.jpg 600w, https:\/\/magnesium-oxide-board.com\/wp-content\/uploads\/2024\/11\/mgo-board-2-768x512.jpg 768w, https:\/\/magnesium-oxide-board.com\/wp-content\/uploads\/2024\/11\/mgo-board-2-800x533.jpg 800w, https:\/\/magnesium-oxide-board.com\/wp-content\/uploads\/2024\/11\/mgo-board-2.jpg 900w\" data-sizes=\"auto\" data-orig-sizes=\"(max-width: 900px) 100vw, 900px\" \/><\/p>\n<h2>4. Corrosion Resistance<\/h2>\n<ul>\n<li><strong>Magnesium Chloride Boards<\/strong><br \/>\nChloride ions can corrode metals like steel, nails, and studs, posing potential risks when used in steel structures.<\/li>\n<li><strong>Magnesium Sulfate Boards<\/strong><br \/>\nFree of chloride ions, these boards are more metal-friendly and exhibit better corrosion resistance.<\/li>\n<\/ul>\n<h2>5. Application Scenarios<\/h2>\n<ul>\n<li><strong>Magnesium Chloride Boards<\/strong><br \/>\nSuitable for wall panels, ceilings, and interior wall decorations. However, they are generally not recommended for use in humid area or scenarios that require corrosion resistance.<\/li>\n<li><strong>Magnesium Sulfate Boards<\/strong><br \/>\nSuitable for bathrooms, kitchens, and other humid environments. They are also ideal for applications requiring high corrosion resistance, such as certain industrial buildings.<\/li>\n<\/ul>\n<h2>6. Moisture Resurgence<\/h2>\n<ul>\n<li><strong>Magnesium Chloride Boards<\/strong><br \/>\nIn humid or rainy weather, these boards may develop surface moisture, efflorescence, or small water droplets.<\/li>\n<li><strong>Magnesium Sulfate Boards<\/strong><br \/>\nThey do not exhibit moisture resurgence under humid or rainy conditions.<\/li>\n<\/ul>\n<p>In summary, both Magnesium Sulfate Boards and Magnesium Chloride Boards are fire-resistant MgO boards, but they differ in moisture resistance and corrosion properties. Magnesium Sulfate Boards are more suitable for humid environments and applications requiring corrosion resistance.<\/p>\n<p style=\"text-align: center;\"><a
