Dimensions of ZNSJ high quality concrete shuttering plywood:
1220*2240*(10-20mm),915*1830*(10-20mm)
Product Features of ZNSJ high quality concrete shuttering plywood :
1,Adopting the high quality poplar ,whole core and first grade,no holes in the middle of plywood
after sawing, which can gurantee the toughness of the template;
2,Using the melamine glue from core to face, high glue concentration, which can gurantee glue adhesiveness ;
3,Adhering them manufacturing principles that each core board is with layer by layer gluing and with high pressure.Layer by layer gluing can fullly bond that impove 10-15% bonding strength. The hot pressure is 120% higher than the theoretical one ,avoiding to reduce pressure to keep the thicknes. The turnover of finished film faced plywood can be up to 10-15time, which ensure product be more durable;
4, two times sanding (secondary molding) before film facing ensure the smoothness of the template without burrs and groove marks.
Product Application of ZNSJ high quality concrete shuttering plywood:
High- rise construction,building construction, forming concrete,can be widely use for building concrete .
