How to evaluate the quality of fiber cement pressure board? These are closely related to the equipment, raw materials, formula, process, production level, management system and management level of the manufacturer. How to choose a real high density fibre cement pressure plate is a problem of concern to everyone. Here are some shopping skills for your reference.we are fiber cement board production line for sale,you can know it.
1. Ask for special specifications:
Compressor-free manufacturers can only produce 6-12 mm thick ordinary cement plate, small press manufacturers can not produce ultra-thin and ultra-thick plate, can not produce ultra-thin plate and ultra-thick plate products manufacturers that their press is too small or even no press, naturally can not produce good fiber cement pressure plate.
2. Computational density:
The quality and density of fiber cement pressure board are closely related. Users can judge whether the board is good or not according to the weight of the board, whether it is fiber cement pressure board or calcium silicate board.
The density of fibre cement pressure board is about 1.8g/cm.
3, the weight of 1200*2400mm in natural state is about 5.5kg/mm, the density of thick plate (15-30mm) is about 1.95, and the weight of 200*2400mm in natural state is about 6kg/mm.
The density of ordinary cement or non-compacted slab is about 1.5 mg/cm3 and the weight is about
4.5 kg/mm. The density of calcium silicate board is about 1.2g/cm3 and 3.5kg/mm.
