Manufacturing method of anti-aging HDPE coarse surface impermeable membrane

Abstract

The invention discloses a manufacturing method of an anti-aging HDPE coarse surface impermeable membrane. The manufacturing method of the anti-aging HDPE coarse surface impermeable membrane comprisesthe steps that an impermeable membrane coiled material is put into a decoiling device, and the end of the impermeable membrane coiled material is unfolded along a workbench of the decoiling device; and then a synchronous roller on the top of the workbench presses the impermeable membrane, the synchronous roller is filled with coarse materials, the coarse materials are sprayed to the surface of theimpermeable membrane through rolling operation of the synchronous roller in the decoiling process, and the HDPE coarse surface impermeable membrane is formed. The manufacturing method of the anti-aging HDPE coarse surface impermeable membrane can manufacture the HDPE coarse surface impermeable membrane at the construction site, achieves effective combination of production and construction steps,is high in flexibility, can accurately control the yield of the HDPE coarse surface impermeable membranes according to the specific construction demand, and is beneficial to sufficient utilization andreasonable planning of materials.

Description

technical field [0001] The invention belongs to the technical field of anti-seepage film manufacture, and in particular relates to a method for manufacturing an anti-aging HDPE matte anti-seepage film. Background technique [0002] At present, the surface of the anti-seepage membrane used in engineering is mostly smooth, and its friction coefficient is very small. It is constructed in sloped areas, such as water channel projects, which are all sloped. The concrete on the surface is not completely solidified. , is prone to slipping, which has a certain quality impact on the project. In the existing technology, the rough surface treatment process of the impermeable membrane must be carried out in the factory due to the limitation of the processing equipment, and cannot be processed on the construction site. Production It is seriously separated from the construction link, which not only affects the construction progress, but also has poor flexibility. It is impossible to accura...
