First, the flood control materials and specifications of the specifications and quality of what?
Specific specifications and quality requirements are as follows:
1, Specifications Model: Specifications 85 * 50 cm * 80 grams, 95 * 55 cm * 100 grams of two. Warp and weft density (root / 10cm) 40 × 40 ~ 48 × 48, the color is white (primary color), the material for the new polypropylene resin. In particular, the length of the woven bag at the bottom of the suture to the top of the Department.
2, the appearance of quality: the same jump length of less than 2cm, with the latitude and longitude silk missing and less than 3, does not allow the needle off, broken line, the volume is not sewn, bright color, not mixed. Tolerance: size (cm) ± 1, warp and weft density (root / 10cm) -2, single bag mass (g) -3.
3, the physical and mechanical properties of woven bags: warp rupture strength (KN / m) ≥ 18, zonal rupture strength (KN / m) ≥ 16, latitude and longitude to the elongation (%) ≥ 15, seam breaking strength (KN / M) ≥ 7, the equivalent hole by O95 (mm) 0.1 ~ 0.5, friction coefficient ≥ 0.3, breaking strength (KN) ≥ 1.2, vertical permeability coefficient (cm / s) 10-3 ~ 10-2.
4, packaging requirements: every 500 woven bags for one, topical black woven cloth packaging, mechanical packing 3 ~ 4 Road, into pieces thickness 35cm ~ 40cm, packaging should be smooth, solid, no damage, no stains, each packing (Such as 85 × 50 type), specifications, quantity, weight, production units, manufacturers, production date............
