Dengfeng City's polyethylene closed-cell foam board for caulking of water channels Yongsheng regular stock
The company has long-term processing and production of closed-cell foam board, polyethylene closed-cell foam board, low-foaming polyethylene closed-cell Foam board, polyethylene caulking board, low-elastic polyethylene foam board, low-pressure polyethylene foam board, low-density polyethylene foam board, high-pressure polyethylene foam board, high-density polyethylene foam board, polyethylene caulking board, Polyethylene closed-cell foam seam expansion board, polyethylene closed-cell foam caulking board, high-pressure polyethylene foam plastic board, polyethylene foam plastic board, polyethylene closed-cell foam board, polyethylene closed-cell foam board, low foaming closed-cell Foam board, closed-cell polyethylene foam board.
Repeated tests by the Academy of Sciences of the Ministry of Communications and other units have proven that its performance is comparable to that of wood, cork, rubber, and asphalt. Polyethylene closed-cell foam boards have been widely used abroad in concrete joints such as roads, railways, bridges, and buildings. In concrete projects such as joints and expansion joints, it is also used in domestic hydropower projects. In the construction of hydraulic expansion joints, closed-cell foam boards are used to replace traditional three-oil-four-felt, asphalt wood, fir boards and other materials, and the tops are filled and sealed with polysulfide sealant. The combination of closed-cell foam board and polysulfide sealant is a new construction technology that breaks many limitations of asphalt fir board expansion joint construction. The construction is convenient, fast, and low in construction cost.
Polyethylene foam caulking board has some characteristics
low density, high recovery rate, independent bubble structure
low surface water absorption and good anti-seepage performance.
Resistant to acids, alkalis, salts, etc., excellent aging resistance
Does not flow at high temperatures and does not expand at low temperatures
2. Compared with asphalt wood boards, polyethylene closed-cell foam boards have advantages
Easy to make
The production of vinyl foam caulking boards only needs to be cut into the required pattern with scissors, and can be operated by ordinary workers. However, asphalt boards require professional woodworkers to use woodworking machinery to make them, and they need to be coated with asphalt after the production is completed. , the required asphalt needs to be heated in a container to boil it into liquid. During the heating process, a large amount of harmful gases are produced, causing pollution to the surrounding atmosphere. However, there is no pollution with polyethylene closed-cell foam boards
Easy to transport
Ethylene closed-cell foam boards can be folded into rolls for transportation, and are light in weight. Wood is relatively bulky. In addition, the country implements forest protection policies, and some areas are not rich in wood at all. The wood needs to be transported from other places, which increases the freight cost of the wood. This has caused the price of wood to rise, causing the price of asphalt wood boards to rise accordingly. However, polyethylene closed-cell foam boards of the same area are much lighter than wood, so polyethylene closed-cell foam boards are much more convenient to transport than wood.
Easy to install
Ethylene closed-cell foam board is easier to install than asphalt wood board. The surface of asphalt wood board is coated with asphalt. It is easy for clothes to be coated with asphalt during installation, and asphalt is not easy to wash. Polyethylene closed-cell foam board This situation does not exist. The polyethylene closed-cell foam board can be installed first and then installed. When installing first, you only need to attach the polyethylene closed-cell foam board tightly to the wooden formwork or steel formwork, while the asphalt formwork requires Install it first, and then add asphalt wood boards, which are generally not rigid enough and easily deformed. This situation does not exist with polyethylene closed-cell foam boards.
Guanqingguan
The asphalt on the exposed surface of the green board is easy to melt during the high temperature season in summer, affecting the appearance of the building, but this does not happen with polyethylene closed-cell foam board.
