Classification of cement boards
Cement board is a building material processed from cement and is widely used in construction. Let's briefly introduce the classification of cement boards today, let's take a look.
Definition of cement board
Cement board is a building material made of cement as the main raw material and processed by a special process. Cement board sits between stone and gypsum board and can be freely cut, drilled and carved, and its properties are also due to gypsum. Plates and boards have the functions of fireproof, waterproof, anti-corrosion, insect-proof, sound insulation, etc. The price is much lower than that of stone. Therefore, it is known as a widely used building material in the construction industry, and cement boards are cast in place. There are also prefabs.
Classification of cement boards
1. Ordinary cement board
Ordinary cement board is the lowest grade of cement board. The size of ordinary cement board is mainly 1200*2400, and the thickness is between 6-12mm. The market price is roughly between ten yuan and twenty yuan. The main components of cement board are cement, fly ash and sand. The cheaper the cement board, the less cement is used. Some manufacturers do not need cement at all to reduce the cost of cement boards.
2. Fiber cement board
Fiber cement boards are also known as fiber reinforced cement boards. The difference between it and ordinary cement board is that various fibers are added as reinforcing materials to improve the strength, flexibility, compression resistance, bending resistance and impact resistance of the cement board. Significant improvement, the added fibers mainly include mineral fiber asbestos, plant fiber pulp, synthetic fiber vinylon, rayon glass fiber, etc., and are divided into chrysotile and non-asbestos sheets according to the added fibers.
3. Fiber cement pressure plate
The fiber cement pressure plate is pressed by a special press, which has higher density, waterproof, fireproof and sound insulation properties, and the bearing is more resistant to bending and impact. In addition to the raw materials, fiber cement pressure panels are also reinforced. In addition, the formula and process are different, and the performance mainly depends on the pressure of the press. We live in fast-paced cities that have long been eroded by noise pollution. We need building materials with good sound insulation, and fiber cement board is the ideal board for us. High-density fiber cement board has excellent sound insulation and good thermal insulation, which are also the characteristics of fiber cement board.
Cement Board Buying Instructions
The main choice is product density. High density is a pressure plate. It requires special presses to produce. According to the density, it is divided into ordinary board, advanced board and special board. Thickness and weight parameters can also be used as quality references. When buying, you must understand the surveyed brand reputation, check the physical performance test report and triple standard certification.
