light 1.2g Thermal Insulation Bricks
Definition:
light 1.2g Thermal Insulation Bricks refer to heat-insulating refractory products made of silica as the main raw material and with an SiO2 content of not less than 91%. In addition to the thermal insulation properties of Insulating silica bricks, light 1.2g Thermal Insulation Bricks maintains the characteristics of silicon bricks to a large extent. The starting temperature of load softening is high, and the volume expands slightly during the heating process, which enhances the integrity of the kiln. The manufacture of siliceous Insulating silica bricks uses finely pulverized silica as the raw material, adding part of the waste silica bricks or waste siliceous Insulating silica bricks powder, mineralizers and burnout additives. Add water to the mixer according to a certain proportion to mix into a mud, which is formed by mechanical or manual molding. After the brick is dried, the residual moisture is less than 0.5% before it can be loaded into the kiln. In order to prevent the violent volume expansion due to the polycrystalline transformation of SiO2, causing cracks in the product, a slower temperature rise and fall speed are required during firing.
light 1.2g Thermal Insulation Bricks also known as silicon insulation brick. Light refractories with silica content over 91% and bulk density below 1.2g/cm3. The refractoriness and load softening temperature are similar to those of common silica brick. However, due to many pores, the compressive strength, slag resistance and corrosion resistance are not as good as those of ordinary silica brick, while the thermal shock resistance is improved.
light 1.2g Thermal Insulation Bricks Advantage:
1. Silicon oxide is above 95%.
2. Good acid erosion resistance.
3. High softening point with temperature.
4. No shrink in burn repeatedly.
5. Temperature of refractoriness under load is above 1650º C
light 1.2g Thermal Insulation Bricks Application:
1). Gas cooker,Water heater,Gas oven, Gas boiler,Air-conditioning and so on.
2). As ceramic parts of flexible pad and channel heaters at operations of pre and postweld heat treatment; Welding process, stress-relieving, pre-heating & post heating, other resistance-heating environment
3). halogen lamps, high and low pressure uv lamps, mercury lamps, uv lamp holders and heating tubes.
4). high-power electrical applicance and all kinds of insulation device.
