研究夹层结构机保车是保温车现代发展阶段一个突出的特点。与其他保温车不同的是内外墙板和隔热结构是一个整体。主要是采用现车发泡并在夹层结构中作为承载元件的泡沫聚氨基甲酸酯起隔热作用。夹层结构机保车与其他保温车比较具有较高的技术经济指标(例如自重小、载重大)、良好的热工性能和气密性。但是这些车辆最重要的优点是在整个使用期限(28年)内车体实际上无须修理。布良斯克机械制造工厂生产联合公司制造、试验了苏联的第一辆夹层结构机保车的 Research sandwich structure Machine Paul car insulation car is a prominent feature of the stage of modern development. And other insulation car is different from the interior wall and insulation structure is a whole. Foam polyurethane, which is currently foamed in the car and used as a carrier element in the sandwich structure, acts as a thermal barrier. The mezzanine structure of the car and other insulation vehicles with higher technical and economic indicators (such as small weight, heavy load), good thermal performance and air tightness. But the most important advantage of these vehicles is that the body is virtually unneeded for the entire service life (28 years).
