The technology requirement of the outdoor playground
1. Plastic parts: Imported food-grade LLDPE engineering plastics are used to completely dissolve the pigment into the granules through the granulation process, milled, and rotomolded to conform to the requirements of GB / T 4454-1996. The wall thickness of the engineering plastic is more than 6mm. , Colorful, infiltration of anti-ultraviolet, anti-static and anti-bleaching elements, safe, environmentally friendly, not easy to age. The fastener is made of zinc-aluminum alloy die-casting, which conforms to (GB / T 13818-1992). The screws are made of stainless steel (in accordance with GB / T1221-1992 accuracy standards).
Second, steel pipe: using hot-dip galvanized steel pipe and fastener connection process, the product iron parts are integrally processed and shaped, and then degreased, derusted, neutralized, phosphated, passivated, shot blasted and other pre-treatment (in accordance with JB-K5607- 1991), the surface is smooth and not easy to rust. Surface sprayed outdoor environmental protection polyester powder coating, anti-ultraviolet, bright color, not easy to fall off, new age; spraying equipment uses computer-controlled imported electrostatic powder spraying device, powder recycling using small cyclone and imported filter, high efficiency, no pollution. The column is made of 114 steel pipes with a wall thickness of 2mm. The specifications of the entire set of slide iron parts are steel pipes Φ28, Φ32, Φ38, Φ48, Φ114.
