Embodiment 1

[0017] Select polymer waterproof sheet 1 and polymer waterproof sheet 2 with enhanced puncture-resistant waterproof sheet thickness of 1.2mm for welding, first turn on the fan, set the temperature to 300°C, and set the walking speed to 1cm / min , preheating for 20 seconds, then press down the operating lever to fix the overlapping pressure of two pieces of the same polymer waterproof sheet to 5kg / cm 2 , that is, turn on the walking speed switch, start crawling welding, observe the bonding strength of the fusion welding seam, and conduct a leak test. If the bonding strength does not meet the requirements or there is leakage, it is necessary to increase the welding temperature or increase the pressure of the overlapping of two polymer waterproof sheets.

Embodiment 2

[0019] Select polymer waterproof sheet 1 and polymer waterproof sheet 2 with enhanced puncture-resistant waterproof sheet thickness of 1.2mm for welding, first turn on the fan, set the temperature to 350°C, and set the walking speed to 3cm / min , preheating for 20 seconds, then press down the operating lever to fix the overlapping pressure of two pieces of the same polymer waterproof sheet to 10kg / cm 2 , that is, turn on the walking speed switch, start crawling welding, observe the bonding strength of the fusion welding seam, and conduct a leak test.

Embodiment 3

[0021] Select polymer waterproof sheet 1 and polymer waterproof sheet 2 with enhanced puncture-resistant waterproof sheet thickness of 1.2mm for welding, first turn on the fan, set the temperature to 300°C, and set the walking speed to 5cm / min , preheating for 40 seconds, then press down the operating lever to fix the overlapping pressure of two pieces of the same polymer waterproof sheet to 5kg / cm 2 , that is, turn on the walking speed switch, start crawling welding, observe the bonding strength of the fusion welding seam, and conduct a leak test. If the bonding strength does not meet the requirements or there is leakage, the welding temperature must be increased to increase the pressure of the two polymer waterproof sheets overlapping each other

Abstract

The invention discloses a method of making for a macromolecular water-proof sheet, and connects two macromolecular water-proof sheets in width of 10-15cm, and then adjusts positions and directions of the macromolecular water-proof sheets and a thermal welding machine. The temperature and the speed of travel are elected via the thickness of the macromolecular water-proof sheet after opening the thermal welding machine, then preheating is performance, and an operation bar is pressed down. After melting and welding, the width of soldered is 2cmX 2cm, and an airway between every two soldered is 1-3cm for checking the leakage. The invention provides a method of making a macromolecular water-proof sheet thereby resolving the question of leakage in macromolecular water-proof sheet.

Description

technical field [0001] The invention belongs to the technical field of building waterproofing, and relates to a construction method of a building waterproof sheet, in particular to a construction method of a polymer waterproof sheet. Background technique [0002] The sheet used for building waterproofing is made of modified rubber and a single synthetic resin, such as polyvinyl chloride, polyethylene and other polyolefin resins. It has small elasticity, low elongation, low tensile strength, The durability and low temperature resistance are poor, resulting in extremely poor waterproof and leakage properties of the coil. Therefore, different waterproof sheets should have different construction methods. The present invention studies the construction method of the polymer waterproof sheet, and solves the problem of leakage of the polymer waterproof sheet. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages and deficiencies ...
