AI Technical Summary
The stress generated during the production of waterproof membranes can cause cracking due to temperature changes after construction, affecting the waterproofing effect and increasing the risk of leakage in buildings.
The machine uses eight rollers evenly distributed inside the frame, driven by a variable frequency motor, combined with a mold temperature controller and an oil cooler. It uses a heat transfer oil circulation pump to heat and cool the waterproof membrane, gradually releasing internal stress and controlling the product size change rate to below 5%.
It effectively releases internal stress in waterproof membranes, ensures product quality, prevents cracking, improves waterproofing performance, and reduces property damage.
