The two or three to five layers of the matrix are separated from the upper part and the lower part, and centimeters, until the impregnation process is completed. After removing the groove, the excessive mixture on the adjacent inner surface of the substrate is scraped off, and the waterproof substrate formed between two or three to five layers forms the upper and lower parts of the formed semi-finished waterproof coil. The surface is of mulch material to make multilayer high efficiency waterproof film. Second World War, the development of the chemical industry, the drilling, production and transportation of oil and natural gas, all contributed greatly to refining.
