Hard silica calcium stone slab is a common insulation material. The main raw materials of hard silica calcium stone slab are calcium hydroxide and quartz sand, and the size can be customized according to usage needs. The finished hard silica calcium stone slab can withstand high temperatures of 1050 ℃, with characteristics such as high temperature resistance, good insulation, high strength, fire insulation, etc. It is widely used in industries, construction, agriculture, and other fields.

Introduction to Features

High strength: Hard calcium silicate stone slabs have high strength, which can ensure that they are not easily broken during construction and cutting, thereby reducing losses during the construction process and saving costs. At the same time, high strength can extend the service life.

Good insulation: The thermal conductivity of hard calcium silicate stone slab is very low, which can reduce temperature conduction and loss, thereby ensuring internal temperature stability. Therefore, during use, hard calcium silicate stone slab has good insulation effect.

High temperature resistance: Hard silica calcium stone slabs can be used at temperatures up to 1050 ℃, which can meet the needs of various high-temperature environments. Therefore, hard silica calcium stone slabs have good high-temperature resistance performance.

Fire insulation: Hard silica calcium stone slabs have good fire insulation performance, and their main raw materials are inorganic substances, so they have non combustible properties and will not produce toxic and harmful gases in high temperature environments.

Application Introduction

The application fields of hard silica calcium stone slabs are also very extensive, widely used in the cement industry, metallurgical industry, petrochemical industry, ceramic industry, glass industry, etc.

Cement industry: mainly used in decomposition furnaces, preheaters, tertiary air ducts, kiln head covers, cooling machines, smoke chambers and other parts.

Metallurgical industry: mainly used in heating furnaces, soaking furnaces, stepper furnaces, annealing furnaces, high-temperature flue, hot air pipelines, etc.
