Fish pond anti-seepage membrane is an anti-seepage geotechnical material produced by the film casting process or blow molding process using high-density polyethylene granules. It has good functions of impermeability, anti-seepage and isolation. Generally, 0.5mm thickness is mostly used. Since the species being cultured usually have high economic value, more new materials are used. The blow molding construction standard has a relatively higher price, while the film casting new material and national standard have relatively lower prices. The cheapest ones are those produced using recycled materials, which are not recommended.
The fish pond anti-seepage membrane has a better welding effect when using a hot-melt double-track welding machine. Some people also use special glue for geotextile membrane to bond for cost savings. The above article mainly introduced welding construction. Now let's introduce the bonding of fish pond anti-seepage membrane.
- Determine the thickness of the geotextile membrane glue according to the local temperature. In summer when the temperature is relatively high, a layer can be brushed on with a brush and then the overlapping surfaces can be quickly overlapped. Of course, before brushing the glue, the parts to be overlapped must be wiped clean. If not wiped clean, leakage may occur and affect the anti-seepage effect.
- When constructing in low temperatures, the glue should be melted and applied thicker with an appropriate widening of the width. Use the heat of the glue to bond quickly, and the effect will be better.
- At present, more electrically heated geotextile membrane glues are used, and the models are also of various qualities. It is necessary to purchase high-quality geotextile membrane glue. The cheap ones cost more than one hundred yuan, and the expensive ones cost more than three hundred yuan. As the saying goes, you get what you pay for. Do not be greedy for cheap and buy geotextile membrane glue with low adhesion.
The above are the methods and construction precautions for the bonding of fish pond anti-seepage membrane introduced by a Shandong anti-seepage geotextile membrane manufacturer. It is hoped that it will be helpful to the bosses in the aquaculture industry. High-quality anti-seepage membranes have a longer service life, and proper welding or bonding can make the anti-seepage membrane play its due role.
