Physical and mechanical properties Item Unit grid tubes require a tensile yield strength Mpa ≥30 2 longitudinal retraction rate% ≤5.0 3 Vicat softening temperature ℃ ≥75 4 drop hammer impact test (0 ℃) a 9/10 is not broken 5 resistance to external load performance KN / 200mm ≥9.5 6 static friction factor / ≤0.35 Abalone grid tube is a porous grid tube, the most obvious feature abalone grid tube is composed of nine square hole of the same size composition Abalone square tube, easy threading and maintenance easy points when sorting tidy. Abalone grid tube Hebei Wang Thai Plastic Co., Ltd. and the State Department communication channels through advanced processing technology formula developed from. Based on polyvinyl chloride (PVC) as raw material with toughening pvc pipe manufacturer grille, anti-aging agents and other auxiliary additives such as, sheathing and sub-tube set for one 9-hole grid tube, once extruded. Because construction is convenient to operate, after the pipeline into production pvc pipe grill manufacturers, can directly penetrate the cable, no longer a second construction. So, gradually replacing some of the traditional products. Zigong grid tubes, Xiong Wang Thai, perforated grille tube provided by Xiong Wang Thai Plastic Products Factory.
