In the interior decoration, especially in the interior decoration of big cities, there is a growing demand for fire. In the process of decoration, a lot of fireproof materials, fireproof boards and other decorative fire-resistant boards and flame-retardant coatings are selected, which are widely used and used in a large amount, but different materials will bring different effects and different decorative properties, How to choose fire-proof board and fire-proof coating? Let's briefly introduce them today.
1、 Performance of fireproof board
The board of fire-proof board manufacturer actually refers to fire-proof board, which is made of fire-proof board and base material by hot-melt adhesive through high temperature and high pressure.
This paper introduces the main physical properties of the base paper produced by Jinan fire-proof board and fire-proof board company through melamine resin and phenolic resin. The melamine thermosetting resin has good luster, good transparency, high surface hardness, wear resistance, high temperature resistance, impact resistance, small pores on the surface, not easy to be polluted, drug resistance, water resistance, It has good solvent resistance, fire resistance, arc resistance, electrical insulation, good mechanical strength and is not easy to aging. After thermosetting, phenolic resin has the properties of heat resistance and hardness.
The fireproof board can be used in furniture surface, door and window cover, skirting line, door panel, background wall, cupboard, display cabinet, office partition, hospital hanging wall, etc.
2、 Performance of fire retardant coating
For the surface protection of passive fire-resistant materials coated with fire retardant coating, the limit value of bear fire test for any protected object, no matter the structure of the building will collapse for a long time in case of fire. The function of fireproof coating is to protect the surface of objects, delay the collapse of buildings, and strive for valuable time for rescue and fire fighting. To be exact, fire-proof coating has its fire-proof limit. When the fire-proof limit is exceeded, the surface of the protected object will catch fire.
1. Make a preliminary inspection on the quality site of the products: cut 2-3 small samples of the basic materials, or take a small number of samples, and apply them to 2-3 pieces of 150 mm × 150 mm plywood, and then paint them according to the actual construction situation. After drying, check the flame of the alcohol lamp. The flame height is about 40mm, and the time of fire spraying is generally 20min. Check the coating foaming. Under normal circumstances, the construction shall be carried out according to the specified amount (generally 500g / m2), the thickness of the bubble layer of the primary fire retardant coating shall be more than 20mm, the thickness of the bubble layer of the secondary fire retardant coating shall be more than 10mm, and the bubble layer shall be uniform and dense.
2 the flame and other strong fire of qualified flame-retardant coating will expand the surface of a large number of bubbles and surface polymerization. There will be no combustion phenomenon for several minutes. The fake and shoddy fireproof coating is basically no foam, and a large number of dispersed slag will appear. Wood will soon burn and damage.
3. Check whether the product has the qualified inspection report issued by the national fire quality inspection center, or check online. The national compulsory product certification system shall be implemented for fire retardant coating, and the fire retardant coating sold on the market shall have the national compulsory product certification certificate and type inspection qualification report.
4. 在实际使用中，为了保证防火涂料的耐火性等性能，一般需要使用一种透明覆膜涂料。防火涂料的用量一般为350 ~ 500克/平方米，覆盖层的用量一般为50克/平方米。
4. In practical use, in order to ensure the fire resistance and other properties of fire retardant coating, a transparent coating is generally required. The consumption of fireproof coating is generally 350 ~ 500g / m2, and the consumption of covering layer is generally 50g / m2.
It can be seen from the above statement and the actual situation of my environment and project based on the needs of fire-retardant coating material selection and fire-retardant board, which can be used in the decoration of high-end offices, star hotels and other high-end public areas or families with enough budget, and can be used for the decoration of fire-retardant board, so that the decoration texture is stronger;
Jinan fumeijia fire-proof board Co., Ltd. can choose fire-proof coating if it is used for decoration of large-area factory buildings, so the cost performance will be higher; https://www.zhumeiyike.com/
