PMI foam composite board

PMI foam composite board is made by mixing polymer materials with cement and mortar to form a slurry, which is manufactured through compression molding process. Compared with traditional building materials, PMI foam composite panels have the characteristics of light weight, thermal insulation, fire and flame retardancy, sound insulation, sound absorption, waterproofing and moisture resistance. At the same time, they also have high strength, are not easily deformed, are easy to construct, and do not pollute the environment. Suitable for thermal insulation of residential, hotel, hotel, office building, school, hospital, station and other civil and industrial buildings.

5. Convenient and fast construction: PMI foam composite board is a product prefabricated by the factory and produced using on-site dry construction technology. Convenient and efficient construction;
6. Good fire resistance: The interior of PMI foam composite board is a mixture of polystyrene as the main material and cement mortar, which has excellent fire resistance.
7. Good sound insulation effect: PMI foam composite board has significant sound insulation effect.

1. Density

Density is an important factor affecting thermal insulation performance. Good materials with low density have good thermal insulation performance; On the contrary, high density results in poor thermal insulation performance. The density grade of PMI foam composite board can be divided into: 100 mm: 120 mm: 130 mm; 140 mm: 140-200 mm: 200-250 mm. PMI foam composite board is a new type of board produced by foaming polystyrene resin and other auxiliary materials through a foaming process, with a density generally around 300-1200 kg/m3. The density of PMI foam composite board mainly depends on the density grade of polystyrene and the type and quality of filling materials. With a limit of 500 kg/m3, the low-density grade is below 500 kg/m3, the medium density grade is between 500 kg/m3 and 800 kg/m3, and the high-density grade is above 800 kg/m3. The filling material of PMI foam composite board is mainly insulation material, mainly polystyrene, phenolic resin, polyurethane, and glass wool. According to different filling materials, their density levels can be divided into the following categories:

2. Thermal conductivity

According to relevant national standards, thermal conductivity is one of the important indicators for measuring the insulation performance of materials, and it is also an important indicator for evaluating whether materials can be used as building insulation materials. The thermal conductivity of PMI foam composite board is between 0.035-0.000, which is at a relatively low level among various insulation materials currently available. PMI foam composite board has been widely used in industries such as construction, chemical, power, textile, light industry, transportation, boilers, pipelines, and cold storage due to its superior insulation performance. 1. Lightweight and High Strength: PMI foam composite board has a light weight and can reduce building loads under the same usage conditions; 2. Fire and flame retardant: PMI foam composite board is non combustible and is currently one of the best fire-resistant and flame-retardant products among various insulation materials; 3. Energy conservation and environmental protection: PMI foam composite board does not produce any harmful substances during use, nor does it cause any pollution to the environment; 6. Economically applicable: PMI foam composite board has a longer service life, lower maintenance costs, and lower overall cost compared to similar products; 7. Wide applicability: PMI foam composite board is suitable for insulation and heat preservation projects of various building walls, especially in some industrial and civil buildings where its advantages are more obvious. 8. Workability: PMI foam composite board is easy to cut and process into shapes.

3. High strength

PMI foam composite board has excellent compressive and impact strength, especially its impact strength can reach more than 20 KN/m2, which has met the requirements of building structure floor. And its flexural strength reaches over 10 KN/m2, which meets the requirements of the floor slab. As a floor slab, its flexural strength is about 3 KN/m2, which is sufficient to resist deformation and fracture of the floor slab. 5. Environmental protection and energy conservation: PMI foam composite board, as a new type of material, meets green environmental standards in both production and use, is non-toxic, odorless, and does not pollute the environment. 6. Economically reasonable: PMI foam composite board is an industrialized production product, and its cost per square meter is only 1/4 to 1/3 of traditional building materials; Traditional building materials such as cement, sand, stone, and bricks are not used during construction to reduce environmental damage. 7. Good seismic performance: PMI foam composite panel wall, as the main load-bearing component of the floor system, can avoid instability and damage of the floor. At the same time, PMI foam composite panels are constructed using fully cast-in-place technology, overcoming the problems of cracks and leakage caused by concrete shrinkage deformation in cast-in-place concrete walls.

4. Stability

PMI foam composite board is made of polystyrene foam, which has good chemical stability and water resistance, as well as high strength and aging resistance, so its service life is longer than traditional insulation materials. 1. It has thermal insulation performance, which can reduce the heat loss of buildings and save air conditioning energy consumption in hot summer; In the cold winter, indoor temperature can be increased to save heating energy consumption. Can be used as insulation material for centralized heating systems or household metering; 2. It has the advantages of lightweight, high strength, fire resistance, lightweight, sound insulation and absorption, moisture and alkali resistance, and good seismic performance; 3. It has good comprehensive performance and can be used in conjunction with any structural wall, making it an ideal building wall material; 4. Green environmental protection: no harmful substance release; No chemical pollution; Non radioactive, it is a truly green and environmentally friendly product. Reduce the number of employees; 6. Low cost: The performance of PMI foam composite board is superior to any insulation material, while also having good fire resistance and flame retardancy. The insulation wall made of PMI foam composite board weighs only 1/5~1/2 of the weight of ordinary concrete walls of the same thickness, thus significantly reducing the construction cost.

5. Production process

The production process is as follows: raw materials - water pouring - static foaming - board removal (curing) - cutting, forming, and packaging. (1) The proportion of raw materials and control during the production process.
1. Raw materials must be strictly inspected according to requirements to ensure they are qualified;
During the mixing process, sufficient water should be added to prevent the occurrence of dry material during foaming;
3. After pouring water, it should be compacted with a vibrator as soon as possible to avoid the formation of hard lumps that affect strength;
4. Cutting and forming must be carried out on a dedicated cutting machine. Ensure that the cutting surface is flat and free from burrs and flying edges;
5. Materials must not be damaged during transportation. If there is any damage, repair it in a timely manner;
6. During installation, handle with care and do not collide or drag materials to prevent damage to the surface of the product.
7. This product belongs to a non load bearing structure and has certain requirements for its load-bearing structure. Suggest determining its load-bearing structure based on local environmental and climatic conditions. Hard materials (such as bricks, mortar, etc.) should be used to enclose the construction site and provide maintenance access.
8. This product is produced by factory prefabrication and on-site construction. The dry construction method is simple to operate, with low labor intensity and high efficiency; At the same time, attention should be paid to avoiding human damage and collisions between various machinery and materials.
