[Prefabricated slab airbag] [Prefabricated slab airbag price standard]

■ Prefabricated slab airbag Specification and quality * prefabricated board airbag price * prefabricated board airbag standard? Prefabricated slab capsules produced by Qingdao High speed Railway Project rubber are products made from vulcanization of rubber and fiber reinforcement layers. They have high tensile strength, elasticity and air tightness. After being filled with compressed air, they can replace the original wood, bamboo and steel molds. They can be reused for many times. They are a supporting product of concrete products that can reduce costs and speed up construction progress
Acceptance criteria of precast slab airbag
At present, there is no unified national and industrial standard for airbag products, so according to the Enterprise Standard of Rubber Factory, the acceptance indicators are as follows:;
