pvc护栏防护层能够形成比较粗糙的表面, 增加对涂层的附着力。磷化处理: 磷化是通过化学方法, 在金属表面生成不溶于水的金属磷酸盐涂层的工艺过程, 是为了提高金属pvc护栏对涂料的附着力和涂膜防腐性能, 作为涂膜保护底层之用。
The protection layer of the PVC barrier can form a relatively rough surface and increase the adhesion to the coating. Phosphating treatment: phosphating is the process of forming water-soluble metal phosphate coating on the metal surface by chemical method. It is to improve the adhesion and coating corrosion resistance of the metal PVC barrier, as the coating to protect the bottom.
pvc护栏除油、除锈处理解读。首先在锌基重防腐+纯聚酯双涂层技术中采用喷丸法, 用引射式喷枪, 将钢丸喷射到pvc护栏表面。pvc护栏表面由于受到钢丸的强烈冲击, 锈斑及氧化膜等被冲掉, 露出pvc护栏本来金属光泽,。
PVC barrier removal of oil and rust removal. The first shot peening method in zinc based heavy-duty + pure polyester double coating technology, using ejector type spray gun, shot injection to PVC surface fence. PVC due to the strong impact of steel guardrail surface, rust and oxide film off, exposing the PVC guardrail have metallic luster,.
pvc护栏静电粉末喷涂体系采用磷酸锌系磷化方法, 采用专用的磷化液处理后, 可以使钢铁基材表面形成均匀、细致的锌系磷化层, 能显著提高涂膜附着力、耐腐蚀性、外观丰满度。pvc护栏粉末喷涂: 经过表面处理后的pvc护栏, 可以进行粉末涂装了。
The electrostatic powder spraying system of PVC guardrail is made of zinc phosphate phosphating process and treated with special phosphating solution. It can make uniform and meticulous zinc phosphating layer on the surface of iron and steel substrate, which can significantly improve adhesion, corrosion resistance and appearance fullness of coating. PVC fence powder spraying: after the surface treatment of the PVC fence, can be powder coating.
