Thermal expansion of UHMWPE is generally more pronounced than that of steel, and the size of the plate changes when the car moves from winter temperatures to high temperatures. If all bolt holes are locked to death and there is no reasonable gap, the plate may be drumming, arching or passing the stress to the pore; if it is too small or poorly processed, it can also produce movement, noise and material drilling. The installation design is designed to establish a fixed baseline and allow a slide direction, rather than treating each hole as a rigid location.
The layout of the plates should be determined in conjunction with the length, temperature difference, material flow and size of available plates. A manageable reference position is usually required and space is left for size changes in other locations through suitable holes, gaskets, fasteners and seams, with values based on material and supplier design. The bolt or pressure is to be kept as smooth as possible with the smoother surface, avoiding the formation of a stand-up step, and not to weaken the necessary levelling in order to pursue the levelling.

The drilling and installation should be preceded by a measurement of the actual car, relying not only on old drawings, as the steel plates used may be deformed. Cuts are smooth, no cracks at the edge of the hole, and the underside of the plate is clean and sharp welding scars are repaired. Tight order prevents the pre-emption of the sheeting to waves, and is carried out in a rectangular and pine-proof manner by means of an installation chart. Welded structures should protect polymers from heat damage, and any changes affecting the vehicle ' s structure should be done by qualified personnel.
After the first heat cycle and the specified time of operation, the bolts, seams and panel flattening are reviewed. Attention is being paid to the long porosity, crotching, plate drumming, tail interference and material entering the plate. The looseness of the solids should not only be condensed over and over again, but must be judged as limiting thermal movement, inadequate pore size, disfigurement of the steel plate or excessive impact. High-temperature fleets in winter and summer can be recorded separately to help optimize the maintenance cycle.
The request is for the size of the car, the steel plate structure, the maximum minimum temperature, the material, the plate layout and acceptable means of installation. The supplier should provide a liner thickness, a pore map, a fast-fix specification and an expansion treatment description. It is the core of avoiding drums, loosening and hangings that allow the plates to be reasonably stretched upwards by the prosecution, while maintaining a secure position.
