What should be paid attention to before cutting HDPE impermeable membrane

by Xinhongji Refractory Xinhongji Refractory Materials What should be paid attention to before cutting HDPE impermeable high quality plastic geonet? Before cutting HDPE geomembrane, the relevant scale should be accurately measured, and then cut according to practice. Generally, it is not suitable to cut according to the scale shown in the figure. It should be numbered piece by piece and recorded in a special form. On the top, when laying geomembrane, we should strive to have fewer welds. On the premise of ensuring quality, try to save the original data. At the same time, it also simply guarantees the quality. The lap width of the joint between the membrane and the wholesale plastic geonet is generally not less than 10cm, usually the welding seam is placed parallel to the large slope, that is, along the slope direction, usually in the corner and deformation section, the joint length should be as much as possible Shorten. Except for special requirements, within 1.5 meters from the top slope or stress concentration area on slopes with a slope greater than 1: 6, no welding seam should be provided as much as possible to prevent artificial wrinkles. When the temperature is low, it should be tightened as much as possible. Flatten HDPE impermeable membrane. All-digital AC servo motor and driver are selected, directly connected to the motor, small size, high efficiency, and extremely low noise. It has high driving rigidity, large acceleration and deceleration acceleration, and improved reliability. Realize constant velocity displacement control, constant velocity experimental force control, constant velocity strain control, control function, all digital hardware implementation, HDPE impermeable plastic geonet manufacturers has strong anti-interference ability, good stability, high degree of software integration, contains a variety of The data experiment specification template is selected to be related to the flatness of the underlying layer, the allowable tensile stress of the data, the elastic modulus of the data, the head and the particle size of the cover layer in the laying range. In addition, it is necessary to consider the use conditions such as exposure, burial pressure, climate, service life, etc., using synthetic fiber or glass fiber as a reinforcement material, and a new type of geotechnical material that is compounded with a composite geomembrane.
