1, seam tape:
Tape material currently widely used mainly for PVC and PU, which is devoted to automobiles, airplanes, aviation and other fields of external decorative and protective film, its advantage is that it has strong durability, acid and ultraviolet radiation, high temperature resistance, good decorative effect. But this method is only a stopgap of the provisional measures.
2, apply sealant at the seams:
Using sealant process commonly used materials are PVC sealant, one-component polyurethane adhesive (glue), high temperature adhesives, the advantage is that weld has a good seal, shock resistance, corrosion resistance, ageing resistance, oil resistance.
3, use trim cover treatment at the seams:
Use trim cover seams overlapped structure, in order to prevent leakage, lapping around coated PVC sealant, operations requirements consistent with the wheel cavity coating, and then the Assembly with decorative cover.
4, joint special welding processes:
Full or intermittent welding seams, no gluing or welding surface blowing ash handling, keep the original weld appearance; intermittent welds Middle intermittent use of PVC sealant filled. Advantages the two coating operation is simple and easy, low cost, high efficiency, performance is better, and for a variety of conditions, there is no coating off the risk of cracking or PuTTY.
Seam coating process of choosing the right approach can not only meet customer cab appearance requirement, and you avoid the coating quality. The appearance of high sheet-metal cab, decorative pieces covered or seam sealant coating technology approach; profile class cab for use in harsh conditions, you can use special methods welding seams.
