Polyethylene closed-cell foam board I believe many people do not understand what it is? What is its role? Polyethylene closed-cell foam board is a new type of joint sealing material in China. Low-foam polyethylene closed-cell foam board is also commonly called polyethylene closed-cell foam board in the industry. This product can be widely applied to river levees, Various types of concrete water-sealing joint projects, such as port ships, underground flooding, hydropower stations, airport bridges, and house sanitation. So what about polyethylene closed-cell foam? Let's take a look at it together.
Polyethylene closed-cell foam board is good
1, no special irritating odor, non-toxic: the regular closed-cell foam board production process is a certain technical support, closed-cell foam board production of materials used are environmentally friendly materials, and therefore the production of closed-cell foam board is no odor Odor is also non-toxic and harmless.
2, chemical stability: closed-cell foam board can withstand most of the acid and alkali erosion, at room temperature is not soluble in common solvents, low water absorption, excellent electrical insulation properties, low density, good toughness, good stretch, electrical and dielectric With good electrical insulation, low water absorption and low water vapor permeability, it shows its strong chemical stability.
3, outstanding environmental protection: In the production of polyethylene closed-cell foam board, because we use the production of materials are environmentally friendly materials, and thus produced polyethylene closed-cell foam board there is no reason not to be environmentally friendly. Moreover, the closed-cell foam board will not cause environmental pollution when it is produced. Therefore, the environmental protection of the closed-cell foam board is still outstanding.
4. The polyethylene foam board has the characteristics of light capacity, high tensile strength, no water absorption, corrosion resistance, high temperature resistance, etc. In addition to these, the environmental protection of the polyethylene foam board is also relatively strong, and the service life of the closed-cell foam board due to polyethylene It is relatively long, which greatly reduces the wood usage rate. Therefore, the use of polyethylene foam board can save wood, which is also the most effective method to save wood materials and achieve energy conservation and environmental protection.
The role of polyethylene foam board
So why do we need to use polyethylene foam board in construction? What is the role of polyethylene foam board? Combining the performance characteristics of polyethylene foam board and some industry experts, Xiao Bian has finally understood The role of ethylene foam board:
1. As the polyethylene foam board has a relatively perfect thermal insulation, it is used as an outer thermal insulation layer in construction. Compared with the inner thermal insulation layer used in previous buildings, the outer thermal insulation layer effectively eliminates the appearance of “thermal bridges†and avoids condensation of buildings.
2. Polyethylene foam panels are used as the outer thermal insulation layer and are constructed of polyethylene foam panels on the outer layer of the main structure of the building. Combined with its high mechanical strength, it can be understood that the use of a polyethylene foam sheet in a building can protect the main structure of the building and prolong the life of the building. At the same time, the polyethylene foam board can effectively reduce the impact of external temperature changes on the deformation of the main structure of the building, and can reduce the harmful substances in the air and the erosion of the ultraviolet rays on the structure to some extent.
3.Because the polyethylene foam board has less water absorption and extremely low water vapor permeability, the use of polyethylene foam board as the outer thermal insulation layer can avoid the condensation phenomenon of the building wall and effectively improve the tidal temperature of the wall. , And further enhance the wall insulation performance.
4. The polyethylene foam board is used as the outer insulation layer, which can be a more stable temperature in the building. External wall insulation is used, and the structural layer with larger wall heat storage capacity is on the inside of the wall, which is extremely favorable for maintaining room temperature stability.
5. It is obvious that the polyethylene foam board is used as the outer thermal insulation layer to effectively avoid the damage to the thermal insulation layer during the decoration process.
Polyethylene closed-cell foam board construction considerations
1, stored in direct sunlight, close to the heat source. Polyethylene closed-cell foam boards should be protected from direct sunlight and can be placed in a dry, ventilated place away from heat.
2, on the rain. Polyethylene foam board can not be placed in the rain, and the placement of polyethylene foam board should be cleaned to prevent deformation of polyethylene foam board.
3, casually split closed-cell foam board. Closed-cell foam panels have a certain closed-cell structure, so do not arbitrarily divide the foam panels when there are no special effects.
4. Do not process the joint portion of closed-cell foam panels. The connection of the polyethylene foam board should be tight, and it must not be disconnected. The joint part of the closed-cell foam board should be flat, so the gap must be handled well and it must be filled and compacted.
Editor's summary: The relevant information on polyethylene closed-cell foam board is introduced here for everyone. I hope this article will help everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.
