What kinds of fiber cement board can be divided into? Its installation steps have these respectively!

Now many decoration companies will use fiber cement board in the process of decoration, because it has good material characteristics, as well as superior plate performance, so it is more classified, can be divided by fiber, according to density, according to pressure and according to thickness. Many friends may not know much about it, nor do they know what steps it needs to go through to install, it doesn't matter if you don't know, in today's article, Xiaobian will introduce the process classification of fiber cement board, as well as the installation steps of fiber cement board.

I, the process classification of fiber cement board

1. Divided by fiber

Cement fiberboard spacing functional fire and waterproof partition lining. Fiber can be divided into asbestos and asbestos free board. At present, paper fiber is mainly used in China.

2. Divide by density

Low density 0.9-1.2g/cm3, medium density 1.2-1.5g/cm3, high density 1.5-2.0g/cm3. Low density is generally used in ordinary building ceiling partition wall and other parts, medium density is generally used in mid-range building partition wall ceiling, high density is generally used in high-grade building steel structure exterior wall, steel structure floor, etc.

3. Divide by pressure

There is no pressure plate and pressure plate. Medium and low density fiber cement board is no pressure plate, high density is pressure plate.

4, according to the thickness

(1) Ultra-thin plate, 2.5-3.5 mm;

(2) Conventional plate, 4-12 mm;

(3) Thick plate, 13-30 mm;

(4) Ultra-thick plate, 31-100 mm.

II, fiber cement board installation steps

1, fire-resistant grade fiber cement board, should be laid longitudinally, that is, the long side of the board and vertical keel parallel, but only the flat side is fixed to the keel, and the flat side falls in the center of the vertical keel wing plate. Do not fix the fiber cement board to the keel along the top or the floor.

2, no fire demand fiber cement board, can be laid longitudinally, can also be laid horizontally.

3. When the fiber cement board is used as the ceiling of the ceiling, it is necessary to keep the long side straight with the vertical keel and adhere to the equal degree.

4, before knocking the nail should first drill on the plate, if you need to knock the nail directly, the nail should be slightly far away from the edge of the board, to prevent the plate crack.

5, fiber cement board and wood keel composite, the application of round nails or wood screws fixed. Fiber cement board and light steel keel composite, using self-tapping screws fixed. Fiber cement board and asbestos cement keel and other non-metallic material base composite, using expansion screw fixed. Between the fiber cement board and the keel, a layer of ribbed rubber pad should be placed to make the appearance of leveling and progress of sound resistance.
