Q:What need to pay attention to when choosing the imported geomembrane?
What needs to note are uniformity of the thickness, acid and alkali resistance, biodegradability, tensile stress limit and puncture strength.
Q:How much does centrifugal pan of glass wool need to invest? ?
The plant is more than 3000, and it can produce finished products.
Q:What geomembrane is used in the dewatering ditch
DMD geomembrane two cloths film one film D non-woven fabrics M PVC plastic film
Q:How to remove the heating film in the fish tank?
Heating rods can stick out the water surface. The temperature knob and wire part has been sealed, so there will be no leakage. If you see there is water vapor in the heating pipe, it does not matter, because that is the water vapor sealed in the tube. This vapor exists because it is difficult to achieve complete vacuum in domestic products. Instead, if you do not put all the heating rods into the water, the water will be unevenly heated. When the part out of the water is cold and the part inside of the water is hot, heating rods will crack, especially at the seal. By then, the water will flow into the rods causing water leakage.
Q:What are the characteristics of HDPE geomembrane?
