Performance | Gypsum Board | Glass Magnesium Board | Iiteracy | Remark |
Composition | Gypsum board raw materials for DSG, starch, foaming agent, kraft paper and so on.Standard paper gypsum board consists of front paper, back paper and plaster core. | Glass magnesium board (commonly called magnesium oxide board) is composed of magnesium oxide + magnesium chloride + 2 layers of glass fiber cloth (grid cloth) + 2 layers of non-woven fabric. | / | In the field of cutting, gypsum board is weaker than glass magnesium board because of the difference of core material composition. |
Fireproof Performance | The fire resistance limit of 50mm metal face gypsum rock wool clean room panel is 1 hour.Combustion performance class A. | Fire resistance limit of 50mm metal surface glassy magnesium rock wool cleanroom panel 1 hour.Combustion performance class A. | 50mm metal faced gypsum rock wool sandwich panel No: fg050374-2018 50mm metal surface glass magnesium rock wool sandwich panel No: dx053353-2017 | / |
Flexural Capacity | The bending capacity of the double gypsum rock wool handmade panel is 1.2-1.3kN / ㎡. | The flexural bearing capacity of double glass magnesite rock wool handmade panel is 1.2-1.3kN / ㎡. | The bending bearing capacity of the metal-faced sandwich panel should not be less than 0.5kN / ㎡. These two types of panels are far greater than the requirements of the bending capacity, and both can be used as cleanroom ceiling panels. | / |
Flatness | Gypsum board is divided into right-angled board surface and wedge-shaped board surface. | Glass magnesium plate is a rectangular plate surface. | The wedge plate surface is similar to an "inverted triangle". It is a thick shape below the tip. | Wedge plates are flatter than rectangular plates. |
Bonding Strength | The adhesive strength of the double gypsum rock wool handmade panel is 0.13-0.16MPa. | The bonding strength of the double glass magnesite rock wool handmade board is 0.1-0.13MPa. | Saint-Gobain plasterboard has an adhesive strength of 0.3 MPa. | The national standard is 0.06MPa, and the bonding strength is much higher than the national standard. |
Bad Phenomenon | Common not waterproof gesso can exist bibulous phenomenon. | Anti - halogen drum cracking phenomenon. | Gypsum is divided into water-resistant paper-faced gypsum board and fire-resistant paper-faced gypsum board. Different gypsum can be selected according to the requirements of use. | / |
