工程质量的基础是工艺设计质量，设备设计·制造和安装质量。优质的工程质量首先来源于出色的涂装工艺设计，往往由于涂装工艺设计考虑不周·不细，而成为设备设计·制造和安装质量的隐患。工程质量直接影响涂装质量·涂装成本和涂装设备的使用寿命。工程质量差将导致涂装质量差·合格率低·设备的可靠性差·故障多·效率低，甚至使喷塑流水线不能正常运行。高水平低工艺设计和设备设计是高工程质量的前提，这也就是要委托技术力量雄厚·经验丰富的公司来设计·承建大型工程的缘由。
The basis of engineering quality is process design quality, equipment design, manufacturing and installation quality. High quality engineering quality first comes from excellent coating process design, which often becomes the hidden danger of equipment design, manufacturing and installation quality due to careless and careless coating process design. The engineering quality directly affects the coating quality, coating cost and the service life of coating equipment. Poor engineering quality will lead to poor coating quality, low qualification rate, poor equipment reliability, many faults and low efficiency, and even make the spray line can not run normally. High level and low process design and equipment design are the premise of high engineering quality, which is the reason why large-scale projects should be designed and constructed by companies with strong technical force and rich experience.
