Heavy-haul 188bet sports betting app download microporous polyurethane under-rail elastic pad passed the technical review of the National 188bet sports betting app download Group

Relying on the National 188bet sports betting app download Group's scientific research project "In-depth Research on Heavy-haul 188bet sports betting app download Technology Upgrading", the research results of "Heavy-haul 188bet sports betting app download Microporous Polyurethane Under-rail Elastic Pad" have recently passed the technical review of the National 188bet sports betting app download Group

　　The elasticity of the track structure largely depends on the conditions such as the under-rail pads

　　The main technological innovations of this research result:One isA three-dimensional network structure macromolecular polymer prepared by using polyether polyols and isocyanates with reasonable chain lengthsSecond isUsing microporous polyurethane flat plate structure to improve the contact relationship between the elastic layer and the concrete sleeper

　　Using the three-dimensional network molecular structure of polyurethane according to a certain cross-linking density
