Silica Board Production Equipment The exterior wall silica board insulation equipment is a type of equipment product developed for the production of silica board, boasting superior performance and stable operational capabilities. It is also versatile, capable of producing various insulation board products such as glass wool board, rock wool board, and exterior wall silica board. Yiqun's silica board products are widely distributed throughout the country. The silica board equipment uniformly penetrates the polystyrene board with nano-grade aerospace materials, where organic and inorganic materials undergo uniform solidification reactions. It not only maintains the traditional advantages of polystyrene board, such as a low thermal conductivity coefficient and excellent heat insulation performance, but also overcomes the drawback of poor flame retardancy in traditional foam boards. In the market, it is a relatively ideal insulation and heat preservation material.
What are the characteristics of silicate polystyrene board? In fact, silicate polystyrene board is made by siliconizing organic polystyrene boards, which is equivalent to applying a layer of fire-retardant material to the surface of the polystyrene granular macromolecules on a common polystyrene board.
Post-siliconized expanded polystyrene has increased bulk density, yet it maintains the original expanded polystyrene's excellent insulation properties. Additionally, it vitrifies under fire, enhancing its fire resistance. However, the fire rating of siliconized polystyrene can only reach B1 level. Moreover, its tensile and compressive strengths are low (tensile strength ≥ 7.5 KPa, compressive strength ≥ 40 KPa), resulting in insufficient toughness. Additionally, it is more expensive than standard B1-grade expanded polystyrene, which diminishes its competitiveness in the market.
Silica-modified boards were successfully developed over several years by Jinan Megatool New Material Development Co., Ltd., representing an upgraded version of the company's original homogeneous boards. These boards combine the advantages of organic and inorganic materials, offering excellent thermal insulation properties and fire-resistant properties.
