Children rides information on national norms
Children's play equipment selection metals information should fit the corresponding provisions of the state standards, industry standards. Shigemi force components of data quality due certificate (a copy should be stamped with the official seal of the supply of information to ensure the authenticity of the certificate of quality), children's play equipment production unit square is responsible for the purchase of data quality and, if necessary, make units should be re-inspection of raw materials.
Children's play facilities welded structure required a good weldability of steel, plain carbon steel carbon content of 0.27% or less, low alloy carbon equivalent should be less than 0.4%. Mechanical parts metal materials used to consider the needs of its mechanical function, heat function, toughness and so on. Welded on the need for forgings and castings should fit the needs of the relevant national norms. Non-ferrous metals should fit the corresponding national or industry standards specification needs, children's play facilities for non-ferrous metals with special needs, should be specified in the design drawings or corresponding technical conditions.
FRP children's play equipment should fit the needs of the relevant national standards, the appearance should be smooth and free from cracks, color uniformity. FRP water slides should fit the following requirements:
1. Resin should be excellent water resistance and excellent anti-aging functions;
2. Glass fiber should be used in E-glass fibers, looks to be outstanding wettability;
3. Thickness should not be less than 6mm, flange thickness should not be less than 9mm.
Children's play equipment - within a water slide chute appearance requirements are as follows
1. Do not allow the existence of bad holes, wrinkles, bubbles, cure bad dipping, cracks, defects and other shortcomings, the back does not allow the existence of bad curing bad dipping, defects, burrs and other shortcomings, cut surface does not allow the existence of stratification, burrs, etc. shortcoming;
2. From 600mm at with the naked eye, can not repair evident traces of scars, uneven color, wove, uneven, collection and other shortcomings.
The selection of polymer materials, should take full account of the needs of the Bureau of molecular data weathering and corrosion resistance, and according to the specific application, to determine its replacement cycle. The content of harmful substances in various polymer materials necessary to control within the scope of the relevant national standards requirements.
When using timber play equipment should be used in strength, not easy to crack the hardwood, wood moisture content should be less than 18%, and the need for fire-retardant and anti-corrosion treatment.
