Primarily, a thermal melting adhesive machine is used to bond the specially designed filter membrane to the core board at a certain temperature, creating a single unit.

2. The advantages of the anti-clogging overall drainage board include high drainage capacity, excellent overall performance, high tensile strength, and good filter membrane permeability. It can expel fine particles together, making it less likely for the filter membrane of the plastic drainage board to clog, thus achieving a good drainage effect.

3. The membrane fabric is made of a special coarse long fiber hot-bonded non-woven geotextile, with a pore size greater than 80UM and a permeability coefficient of 5X10CM/S.

4. Standard B-type drainage boards should use non-woven fabric at 80 grams per square meter. C-type drainage boards should use non-woven fabric at 90 grams per square meter for the filter membrane. Its longitudinal dry strength is 25N/CM. Lateral wet strength is 22N/CM.

5. High melt index polypropylene and polyethylene are used as raw materials for the core board.
