In modern construction engineering, the use of fiber cement board, calcium silicate board and glass magnesium board is very much. So, what are the specific differences? Below, let's take a look together!
Fiber cement board:
Composition: plate made by molding, steam or high pressure steam curing. Material: Use organic synthetic fiber, inorganic mineral fiber or cellulose fiber as reinforcing material, use cement or cement with silica and calcium materials to replace part of cement as cementitious material (the total amount of silica and calcium materials shall not exceed 80% of the total amount of cementitious material).
Scope of application:
1) Low-density board: it is only suitable for areas that are not directly affected by the sun, rain and snow.
2) Medium density board: it is suitable for areas that may be directly affected by the sun and rain, and generally shall not be used in frozen areas.
3) High-density board: suitable for areas that may be directly affected by the sun, rain and snow.
Calcium silicate plate:
Composition: After pulping, billet, steam feeding, surface sanding and other processes made of the board.
Material: ORGANIC synthetic fiber, inorganic mineral fiber or cellulose are used as reinforcing materials, and silica and calcium materials are added to cement as cementitious materials (the total amount of silica and calcium materials exceeds 80% of the total amount of cementitious materials).
Scope of application: USED in building (partition) wall, especially suitable for high-rise and super high-rise building partition wall, also suitable for wet environment in the bathroom and kitchen (the wall should be pasted with tile or brush waterproof paint).
Glass magnesium plate:
Composition: MAGNESIUM oxide, magnesium chloride, and water ternary system, by configuration and adding modifier and made of stable performance of magnesium cementing material, with alkaline glass fiber net as reinforcement material, with light material as filler composite made of new non-combustible decorative material.
Scope of application: It is widely used as wall board and ceiling in interior decoration.
The specific difference between fiber cement board and calcium silicate board:
1. In terms of raw materials, the difference between calcium silicate board and fiber cement pressure board is mainly that the cement content of calcium silicate board is small, and the cement is replaced by slaking lime and fly ash, while the fiber cement pressure board is mainly made of Portland cement.
2, fiber cement board products than calcium silicate board density, higher strength, longer service life, in the application of external walls more prominent advantages.
3, fiber cement board products in the swelling rate, water absorption, strength performance is more superior, product application range is broader than calcium silicate board.
The difference between fiber cement board and glass magnesium board:
Raw material: glass magnesium plate for magnesium oxide, magnesium chloride chemical reaction products, is integrated. Cement fiberboard is the aggregate of cement and sand, which is a physical reaction.
Color: glass magnesium board is generally milky white, is the color of magnesium oxide and magnesium chloride raw materials, and cement board is the dark cement.
The density of glass magnesium board is between 0.9 and 1.3, which belongs to light fire board, while the density of cement board is above 1.5, which belongs to a heavier building material.
The glass magnesium plate can be bent with a diameter of 30cm without damaging its physical properties. Magnesium chloride plate is brittle and easy to break.
Glass magnesium plate contains free chloride ions, which will corrode steel, metal, etc., while cement plate will not.
Deep processing performance: the glass magnesium board can be hot pressed triamine paper, cold pressed fireproof skin, technical wood, etc., while the cement board deep processing category is not so extensive.
