Product introduction

Tunnel waterproof board production process using the domestic advanced two co-extrusion single screw extrusion method, from raw material resin by adding reinforcing agents, antioxidants, by heating and melting, plasticizing, extrusion molding, hauling the formation of the sheet, but also with a good sling geotextile heat synthesis of a composite waterproofing board, but also can be used in the extrusion and calendering method, that is, the resin extruder Banyan melting and plasticizing, extruded from the head of the slit die extrusion of the molten sheet of billet It can also use extrusion calendering method, i.e. the resin extruder will melt and plasticize, extruding the molten sheet from the slit die mouth of the machine head, fusing it with the sling, and then calendering and cooling it into a glossy film through the roller, or fusing it with the geotextile with the sling, and then calendering and cooling it into a composite waterproof sheet through the roller.

Performance characteristics

Resistant to chemical corrosion, ultraviolet radiation; aging resistance, good abrasion resistance; strong puncture resistance; easy construction, no pollution.

Purpose of action

New railroads, highways, municipal roads, light rail transit construction (including bridge decks, tunnels), roofing, waterproofing of underground works, water conservancy construction, sewage treatment works, chemical acid and alkali treatment pools and other projects seepage corrosion-resistant, liner use.
