What Are the Types of Density for Calcium Silicate Board and How to Distinguish?

Density Classification of Calcium Silicate Board

The density of calcium silicate board is generally divided into three types: low density, medium density, and high density. Specifically, the density range of calcium silicate board is approximately between 0.3 to 2.1. Those with a density below 0.6 can be called low-density calcium silicate board, while those with a density above 0.6 belong to medium density or high-density calcium silicate board.

It is important to note that the density of calcium silicate board is not directly related to its thickness. The size of its density mainly depends on the manufacturer’s production process and the specific requirements of the customers. Low-density calcium silicate boards are usually lighter and suitable for occasions that have strict requirements on weight, while high-density calcium silicate boards are more sturdy and durable, suitable for application scenarios requiring higher strength.

Thickness and Common Specifications of Calcium Silicate Board

The thickness range of calcium silicate board is quite wide, varying from 4mm to 100mm, among which 6mm to 50mm is the more commonly used thickness.

Calcium silicate boards of different thicknesses are suitable for different application scenarios. For example, thinner calcium silicate boards (such as 6mm) can be used for interior ceilings and ceilings, while thicker calcium silicate boards (such as 24mm) are more suitable for walls and other places requiring higher strength. Lightweight low-density boards with thicknesses of 20-100mm or medium-high density boards with thicknesses of 20-100mm are mostly used for thermal insulation of industrial equipment. In addition to thickness, calcium silicate boards also have fixed production specifications. The common specifications are 1.22m × 2.44m and 1.2m × 2.4m. These specifications are designed to facilitate production and transportation, and at the same time, make it convenient for cutting and installation on site.

Uses and Safety Precautions of Calcium Silicate Board

Calcium silicate board is widely used as an interior decoration base similar to gypsum board. It can be used for interior ceilings and ceilings, and can also be used for walls or industrial kilns. Its excellent fireproof, moisture-proof, and soundproof properties make it an ideal choice among building decoration materials. When used in industrial kilns, it has good thermal insulation performance and can withstand temperatures up to 1000°C.

The cutting of calcium silicate boards is very convenient. They can be cut and installed directly at the construction site after production. However, when cutting the boards, the cutter needs to wear a mask to avoid inhaling excessive dust. Cutting calcium silicate boards generates a certain amount of dust, and if inhaled excessively, it may affect health. Therefore, wearing masks and other necessary protective equipment is very important.

Through the detailed introduction of the above three subtitles, I believe everyone has a more comprehensive understanding of the density classification, thickness and specifications, and usage and safety precautions of calcium silicate boards. Whether choosing the appropriate density, determining the appropriate thickness and specifications, or paying attention to safety during the construction process, these are important factors to consider when using calcium silicate boards.
