Solar modules generally need to be placed in the natural environment and undergo wind and rain in various environments. So how can solar energy maintain normal operation in such a harsh environment? This is inseparable from the role of Teflon waterproof and breathable membrane.
Since solar energy is in a sealed state, junction boxes that work outdoors for a long time are subject to temperature fluctuations, wind, rain, and solar radiation. Rapid temperature changes caused by component heating and ambient conditions can therefore lead to sharp pressure changes inside the terminal box. Just like rain and snow, it is easy to cause the internal temperature to drop, forming a 200mber vacuum in the junction box, causing cracks in the housing sealing ring. If this is the case, moisture, rain and dust will enter the inside of the junction box. If not cleaned in time, it will corrode the components inside the junction box and render the junction box functionally ineffective.
No cracks will appear in time. In humid air, due to the cold and hot changes in the air, condensation will also occur inside the junction box. These condensations will not appear when it is completely sealed. It is also difficult to discharge it in this state. So how to solve the condensation problem inside the casing? To this. A solution was proposed, which is to only install a layer of Teflon waterproof and breathable membrane on the shell. These problems can be solved very well. Teflon waterproof and breathable membrane is hydrophobic, breathable and dustproof. The pore diameter is 0.1-1 micron, which is 10,000 times smaller than water beads, making it impossible for moisture to pass through. It protects components well, avoids liquid erosion, and increases product service life. The micropores are 700 times larger than water vapor, which prevents water from entering while allowing air to pass smoothly, which can dissipate heat well and prevent fogging inside the product. Ensure the long-term use of electronic components in the junction box. The microporous channels form a network structure in the membrane, and the micropores are distributed evenly and densely to block dust and achieve good dust-proof effect. The protection level can reach IP68. Interested parties can enter the store for consultation and purchase!
