Does the geomembrane be used as an experiment?
Geomembrane is to do the experiment, in general, geomembrane manufacturers need to do factory experiments, substandard products can not be manufactured, when the geomembrane transported to the site, the site of the site will do their own experiments, and some sites Will be sent to a dedicated testing organization to do the experiment, the general experiment to take six samples of testing, about each batch of goods to do an experiment 1, test purposes 1. To test the different materials geomembrane solderability and adhesiveness. 2. The welding operators to carry out professional training, so that welding operators to master the geomembrane welding machine technical parameters, working principle, operating procedures and seams of the quality standards, skilled operation of geomembrane welding machine. 3. Determine the welding temperature, crawling speed and operation method of the welding machine under different material conditions. 4. Determine the "T" type lap welding method. 5. Determine the type of adhesive used in geomembrane bonding, manufacturer and construction process. 6. In determining the welder model, welding temperature, crawling speed and other welding construction technology, geomembrane joints of the indicators meet the specification requirements. 7. In determining the binder model, the manufacturer and the construction process, the geomembrane joints of the indicators meet the regulatory requirements. 8. To determine the quality of geomembrane seams detection methods, so that the test staff master master geomembrane seams quality control and testing methods, standards and testing frequency
Of course, the standard is GB / T-2008 "geosynthetics non-woven composite geomembrane" revision. This standard specifies the nonwovens composite geomembrane product classification, specifications, code, technical requirements and quality assessment, test methods, inspection rules, packaging, signs, storage and transportation. This standard applies to non-woven geotextile as the substrate, with polyethylene, polyvinyl chloride and other films, composite non-woven composite geomembrane. This standard is the GB / T-1998 made the following technical changes: - standard name changed to "geosynthetics non-woven composite geomembrane"; - product specifications from the unit area of ??the quality to nominal breaking strength; - the product code is simplified from 7 parts to 5 parts; - the original standard in Table 1 and Table 2 for integration, fracture strength, tear strength, CBR burst strength indicators are specified specific indicators, and increase the file requirements ; - the elongation at break is changed to the standard strength corresponding to the elongation; - the width is changed to the reference index, the mass per unit area is no longer used as the assessment index; - simplifies the appearance inspection; - simplifies the packaging, standard.
Hello, geomembrane is to do the experiment, in general, geomembrane manufacturers need to do factory experiments, substandard products can not be manufactured, when the geomembrane transported to the site, the conditions of the site will do their own experiments, And some sites will be sent to the specialized testing organizations to do the experiment, the general experiment to take six samples of testing, about each batch of goods to do an experiment, geomembrane manufacturers in the Swiss Zhang Ming Chao answer for you.
