Advantages of high molecular polyethylene fender board: 1. Ultra high molecular polyethylene (PE) veneers are installed in front of the fender board, which can reduce the friction coefficient between the ship and the fender (below 0.2), greatly reduce the shear force (horizontal force) generated by the fender when the ship is berthing, thus improving the life of the fender. 2、 The impact plate is generally of closed structure, with high strength and good anti-corrosion performance. 3、 Because

1. Thermal insulation performance: thermal conductivity of polyurethane is 0.022W/(m · K), EPS is 0.041W/(m · K), XPS is 0.028W/(m · K). 2. Tightness: EPS and XPS are bonded with seams and cavities, and the external air can easily flow through the seams and cavities, affecting the insulation performance. If the factor that there are gaps in the cavity is taken into account

We often see that some design units point out in the technical specification of anti-corrosion coating that polyurethane finish or acrylic polyurethane finish should be used as the finish paint, and then the paint purchasing unit makes an inquiry from the paint manufacturers according to this name in the inquiry list, but the prices quoted by the manufacturers are different, or even several times different. Why? This is because there are many kinds of polyurethane finish

Soft polyurethane foam refers to soft polyurethane foam plastic, which is a flexible polyurethane foam plastic with certain elasticity. It is a polyurethane product with the largest amount of polyurethane products. The polyurethane soft foam is mostly of open cell structure, which has low density, good elastic recovery, sound absorption, breathability, heat preservation and other properties. It is mainly used as furniture cushion, mattress, vehicle seat cushion and other cushion materials

Polyurethane is an important synthetic polymer material, especially polyurethane foam is widely used in furniture, building energy conservation and other fields. However, polyurethane not only needs non renewable petroleum resources as raw materials in the production process, but also is difficult to be recycled after use, which is not conducive to sustainable development. A new study is expected to change this situation. The synthesis of polyurethane requires polyols and isomers

For all kinds of articles in life, our feelings about them are intuitive, such as the concepts of hardness, elasticity, toughness, brittleness, etc. This information obtained through intuitive feeling and perception is generally called qualitative judgment. Qualitative judgment is usually vague, imprecise and not conducive to comparison. Just as we know that iron is hard and steel is hard, which one is harder, except for the two
