[0002] Waterproof membrane is a key material used for building waterproofing. It is usually made into flexible rolls that are easy to transport and install. Waterproof membrane is the first line of defense in building waterproofing. When choosing it, factors such as project requirements, usage environment, and budget must be considered. Polymer-modified bitumen membrane is currently a widely used mid-range option, while synthetic polymer membrane is often used in situations with higher performance requirements. Waterproof membrane needs to be cooled during processing, therefore, a cooling equipment for waterproof membrane processing is needed.

[0003] Existing cooling equipment for waterproof membrane processing typically uses circulating coolant to cool the membrane directly. However, waterproof membranes are prone to oil contamination during processing. Directly cooling the membrane with coolant can cause oil to seep into the coolant, contaminating both the coolant and the membrane. This reduces the lifespan of the cooling equipment. Furthermore, stubborn oil can damage the membrane's density and even create seepage channels, directly reducing the waterproof reliability and durability of the membrane, thus failing to meet user needs.
