What is a refractory board countertop, the difference between refractory board and flame retardant board

by:KingKonree     2021-05-01

Refractory board is a refractory building material for surface decoration. It is widely used in interior decoration. It is mainly used for the selection of countertops and cabinet materials. Today we mainly introduce the application of refractory board in countertops.

Advantages and disadvantages of refractory board countertops

Advantages: Refractory board countertops are the mainstream in the current cabinet market, and its rich The color and light figure can be matched with different styles of cabinets to create a modern kitchen. Refractory board has the characteristics of fire prevention; moisture resistance; chemical corrosion resistance; abrasion resistance; easy to clean.

Disadvantages:

1. Mostly low-priced density board

Domestic use for the manufacture of refractory The material of the board is mostly low-priced density board, which cannot provide effective guarantees in terms of performance and environmental protection.

2. Seamless splicing is very difficult

The length of refractory plates is limited, and the joints of corner table splicing lack effective treatment methods, and it is impossible to realize the overall perfect seamless splicing. The gap is naturally a 'hotbed' of bacterial dirt. Therefore, it is more suitable for a font design. Therefore, such countertops are easily infiltrated by water, which can easily lead to degumming, deformation, and expansion of the substrate when processed or used improperly.

Suitable crowd: users who pursue fashion and simplicity.

The difference between refractory board and flame retardant board

Refractory board: Refractory board is a refractory building material for surface decoration, which is widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, exterior walls and other fields. Refractory board is made of base paper (titanium powder paper, kraft paper) through melamine and phenolic resin impregnation process at high temperature and high pressure. The refractory board specifications are: 1000*2000/1220*2440. The thickness is: 5mm, 8mm, 10mm. There is no national or industry standard for refractory board (and its combination), but it should meet CECS200: 2006 'Technical Regulations for Fire Protection of Building Steel StructuresRadionuclide Limits of Building Materials 'Class A' and the relevant requirements of GB50325 'Code for Indoor Environmental Pollution Control of Civil Construction Engineering'.

Flame-retardant board: In the building materials market, flame-retardant board has many names, such as flame-retardant plywood, flame-retardant plywood, flame-retardant board, etc. This kind of board is peeled from logs into wood chips or A three-layer or multi-layer plywood made of wood chips cut into small wooden squares, fire-retardant treatment of the wood chips and then glued with an adhesive. Usually an odd number of layers of wood chips are used, and the fiber directions of adjacent layers of wood chips are glued perpendicularly to each other. to make. It can generally overcome the defects of wood and greatly improve and improve the physical and mechanical properties of wood. At the same time, flame-retardant plywood also overcomes the shortcomings of ordinary plywood that is easy to burn, and effectively improves the flame retardant performance of plywood. This kind of flame retardant board has the five characteristics of flame retardancy, smoke suppression, corrosion resistance, insect resistance and stability at the same time, which can be said to have strong practicability.

In the process of using, we should pay attention to the use of the refractory board as soon as possible after the use of the water, water stains should be wiped dry as soon as possible to avoid long-term Soaking in water can prevent the surface from opening and deforming, thus ending the service life of the refractory board ahead of time.
