Product implementation standard: GB/T17642-2008 "geosynthetic materials nonwoven composite geomembrane"
Chart:
1. Material quality
(1) The polyethylene geomembrane used in the product should meet the provisions of GB/T 17643, and other membrane materials should also meet the requirements of the corresponding standards.
(2) The nonwoven geotextiles used in the product shall meet the requirements of GB/T 17638 or GB/T 17639.
2. Intrinsic quality
(1) Intrinsic quality is divided into basic items and selection items. The technical requirements of basic items are shown in Table 1, where items 1 -- 7 are assessment items and items 8 are reference items.
(2) The selection items include dynamic penetration, puncture strength, in-plane water flow, friction coefficient, UV resistance, acid and alkali resistance, oxidation resistance, creep property, splicing strength, wear resistance, elongation at constant load, elongation at constant load and elongation at break, etc. The standard value of the option is agreed upon by all parties.
(3) When certain indicators required by the demander cannot be met at the same time, the two parties can negotiate to meet the main indicators in engineering application as the principle, and take other indicators into account.
Appearance quality
Appearance defects can be divided into minor defects and major defects (see Table 3). Heavy defects are not allowed on each product, and light defects should not exceed 5 per 200m².
