Abstract

The present invention discloses an extrusion casting machine calendering apparatus, which comprises an extruder, a die, a calendering rack, a base, a calendering roller set, a glue roller and a water tank, wherein the calendering roller set and the glue roller are arranged on the calendering rack, the water groove is arranged below the calendering roller set, the die is arranged above the calendering roller set and is connected with the extruder, the calendering rack is arranged above the base, and a stretching device is arranged between the base and the calendering rack. With the equipment of the present invention, the produced geomembrane sheet thickness range is wide, the geomembrane and the geotechnological composite material can be concurrently produced, and the defect that the membrane blowing method can not produce the composite material is overcome.

Description

technical field [0001] The invention relates to the field of extruder equipment, in particular to a calendering device of an extrusion casting machine. Background technique [0002] Geomembrane is a geotechnical anti-seepage material composed of plastic film as the anti-seepage base material and non-woven fabric. Its anti-seepage performance mainly depends on the anti-seepage performance of the plastic film. At present, plastic films for anti-seepage applications at home and abroad mainly include polyvinyl chloride (PVC), polyethylene (PE), EVA (ethylene / vinyl acetate copolymer), and ECB (ethylene vinyl acetate modified film) is also designed for tunnel applications. Asphalt blend geomembrane), they are a polymer chemical flexible material with small specific gravity, strong extensibility, high adaptability to deformation, corrosion resistance, low temperature resistance, and good frost resistance. [0003] At present, there are two main methods for producing geomembrane sh...
