Introduction: The continuous innovation of building materials has led to the continuous progress and development of the construction industry and decoration. From the original dingmao structure to the current reinforced concrete structure, people's own wisdom has continued to transform us over the long years. environment. Not only has the structure of the house changed, but the materials have also undergone a drastic change. Today, the editor will briefly introduce two different building materials to you. These two materials are also commonly used by everyone.

Plastic aluminum panel

As a new type of decorative material, aluminum-plastic composite panel (also known as aluminum-plastic panel) has been introduced to China from South Korea in the late 1980s and early 1990s. , it is quickly favored by people because of its economy, variety of optional colors, convenient construction methods, excellent processing performance, excellent fire resistance and noble quality. In foreign countries, aluminum-plastic panels have many names, some are called aluminum composite panels (Aluminum?Composite?Panels); some are called aluminum composite materials (Aluminum?Composite?Materials); in many European countries, aluminum-plastic panels are called Alucobond , a brand name derived from aluminum-plastic panels.

There are not many foreign companies that produce aluminum-plastic panels, but their production scale is large. Famous ones include Alusuisse Company headquartered in Switzerland, Reynolds Metal Company of the United States, Japan's Mitsubishi Corporation, South Korea's Daeming, etc. Taiwan is auspicious, and famous mainland companies include Jiangxi Yalitai, Huatian Aluminum, Shanghai Huayuan, Ningbo Aijia Building Materials, etc.

Characteristics of plastic aluminum plates

It is composed of two materials (metal and non-metal) with completely different properties. It retains the original composition materials (metal aluminum, non-metal polyethylene plastic ), and overcome the shortcomings of the original constituent materials, thereby obtaining many excellent material properties, such as luxury, colorful decoration, weather resistance, corrosion resistance, impact resistance, fire protection, moisture resistance, sound insulation, and heat insulation , earthquake resistance; light weight, easy to process and form, easy to transport and install. Therefore, it is widely used in various building decorations, such as ceilings, pillars, counters, furniture, phone booths, elevators, storefronts, billboards, factory wall materials, etc., and has become one of the three major curtain walls (natural stone, glass curtain wall, metal Curtain wall) is the representative of metal curtain wall. In developed countries, aluminum-plastic panels are also used in the manufacture of buses and train carriages, sound insulation materials for aircraft and ships, and the design of instrument cabinets.

Fireproof board

Fire-resistant building materials for surface decoration, widely used in interior decoration, furniture, kitchen cabinets, laboratory countertops, exterior walls and other fields. Fireproof board is made of base paper (titanium powder paper, kraft paper) impregnated with melamine and phenolic resin under high temperature and high pressure.

Classification

1. Mineral wool board and glass wool board: Mineral wool and glass wool are mainly used as thermal insulation materials. It is non-combustible, has good high-temperature resistance, and is lightweight. However, its shortcomings are: 1. Short fibers can cause harm to the human respiratory system, 2. The strength of the board is poor, 3. The board has poor barrier properties against the spread of fire smoke, 4. The decorative properties are poor, and 5. The installation and construction workload is heavy. Therefore, most of this kind of boards have evolved into boards with inorganic bonding materials as the base material and mineral wool and glass wool as reinforcing materials.

2. Cement board: Cement board has high strength and comes from a wide range of sources. In the past, it was often used as fireproof ceilings and partition walls, but its fire resistance is poor. It is easy to burst and perforate in fire scenes, and loses its protective effect, which limits its application. Cement concrete components have good heat and sound insulation properties and can be used as partition walls and roof panels. Improved varieties such as fiber-reinforced cement boards have gradually appeared in the building materials market, which have the advantages of high strength and good fire resistance, but have poor toughness, high alkalinity, and poor decorative effect.

3. Perlite board, floating bead board, vermiculite board: they are based on low-alkalinity cement, perlite, glass beads, and vermiculite are aerated filling materials, and some additives are added Hollow panels made of composite materials. It has the characteristics of light weight, high strength, good toughness, fire protection and heat insulation, and convenient construction. It can be widely used in non-load-bearing parts such as sub-rooms, households, bathrooms, kitchens, and communication pipes of high-rise frame buildings.

4. Fireproof gypsum boards: Since the fireproof properties of gypsum have been widely accepted, fireproof boards based on gypsum have developed rapidly. The main component of this board is non-combustible and contains crystal water. It has good fire resistance and can be used as partition walls, suspended ceilings and roof panels. The raw materials of this board are rich in sources and are convenient for factory-specific production. In use, it has a light weight, which can reduce the building load-bearing, is easy to process, can be sawed and planed, is convenient for construction, and has good decorative properties, but its bending resistance is poor. There are many factors that affect the fire resistance of gypsum boards, such as composition, type of board, type of keel, thickness of the board, presence or absence of fillers in the air layer, assembly method, etc. In recent years, new varieties such as calcium silicate gypsum fiberboard and double-sided sticker gypsum fireproof board have appeared.

5. Calcium silicate fiber board: It is a building board made of lime, silicate and inorganic fiber reinforced materials as the main raw materials. It has light weight, high strength, heat insulation, good durability and processing performance. It has the characteristics of excellent construction performance and is mainly used to make ceilings, partition walls and as fire protection materials for steel columns and steel beams. However, the strength and bending performance of the plate need to be improved. 6. Magnesium oxychloride fireproof board: It is a magnesium oxychloride cement product. It is composed of magnesium cementitious material as the main body, glass fiber cloth as the reinforcing material, and lightweight insulation material as the filler. It can meet the non-flammability requirements and is A new type of environmentally friendly board.

The essential difference

The essential difference between the two materials is that the fireproof board is made of non-metallic materials, while the plastic aluminum board is made of metal and non-metallic materials.

Conclusion: The above is the relevant information about aluminum-plastic panels and fireproof boards that the editor will tell you today. I believe everyone has a simple understanding of this information after reading the editor's narration, right? In fact, whether aluminum-plastic panels or fireproof boards are better? This question is a bit of a matter of opinion. The main reason is that the uses of these two materials are different, so there is no way to compare. You should choose according to the actual situation!
