1. Organization

In terms of crystal particle size, the compressive strength of some fine-grained rocks or cryptocrystalline rocks is often greater than that of coarse-grained rocks. Due to the different types of natural rocks used in the production process, the size of the crystal particles produced varies. However, the crystal particles produced from basalt are very small and have high compressive strength.

2. Properties of cement

The properties of the adhesive mainly depend on the adhesive used in the production process. According to its system structure, it can be known that it consists of a bonding layer, insulation layer, plastering layer, decorative layer, and accessories. Both the bonding layer and plastering layer use adhesive, so their compressive strength should be good. However, it should be noted that due to the different quality of the adhesive, its actual situation is also different.

3. Direction of pressure

Its compressive strength is also determined by the direction of compressive stress. It has layers, and if the direction of stress is perpendicular to the layer, its compressive strength is very high. In fact, there are many factors that affect the compressive strength of polyurethane composite panels, but the properties of the structure, adhesive, and pressure direction are the main ones. Therefore, we should pay attention to selecting high-quality production materials and adhesives during the production process.

Characteristics of polyurethane insulation board:

Polyurethane rigid foam is a new type of polymer material with excellent properties such as low bulk density, low thermal conductivity, high closed cell rate, and corrosion resistance.

Polyurethane foam board has the characteristics of light capacity, high strength, heat insulation, sound insulation, cold resistance, corrosion prevention, non water absorption, simple and fast construction, etc.

Application of polyurethane insulation board:

Polyurethane foam board is mainly used for central air conditioning, cold storage, cold storage room, light body room, low-temperature box and fresh-keeping box. It is also a material used for insulation, waterproofing, sealing, and other purposes in industrial sectors such as construction, transportation, petroleum, chemical, power, and refrigeration.

At present, the energy-saving construction technology of polyurethane rigid foam is gradually maturing and developing rapidly. It has been widely promoted and applied in cold regions, extremely cold regions, and hot summer and cold winter regions in China, and has achieved gratifying energy-saving effects.

Polyurethane foam board:Using high-performance polyether polyols and multiple methyl polyphenyl isocyanates as the main raw materials, catalysts and foaming agents are usedUnder the action of surfactants, it is foamed through chemical reactions.

Polyurethane composite insulation board:It is a new type of insulation material with high insulation and high flame retardancy, which is made by mixing inorganic fireproof rolls and polyurethane foam with other additives in proportion under certain conditions and processed in one go by a fully automated production line. It is suitable for external insulation of various building walls.

Composite fire resistance performance:Polyurethane composite board is a flame-retardant self extinguishing material with a softening point of over 250 degrees Celsius, and only decomposes at higher temperatures. When burning, polyurethane will form ash on its foam surface. This layer of ash will help isolate the foam below and effectively prevent fire spreading. After the improvement of the production process, the fire-resistant and flame-retardant fiberglass cement cloth is compounded again, which meets the non combustible standard.
