彩涂板在加工过程中的质量要求是什么

物理性能是考虑成形性的关键指标值,是确定和调整制造工艺的关键参数。因此,在生产和加工中应首先考虑物理性质。铅笔硬度、T弯、冲击功等指标值与生产加工特性密切相关,也应予以考虑。当零件外观复杂、变形程度大时,应选择多道次成形。如果多次成形,会引起过度变形,破坏涂层与基体之间的总铁结合力。
在生产加工过程中,应根据外观、变形特点、加工工艺标准等因素设置适当的间隙,设置间隙时应考虑涂层厚度。大多数涂层可用作固体润滑剂,并可考虑大多数成形过程的润湿规律。一些建筑涂料可以根据调整秘方来提高涂料的润湿性。如果涂层的润湿性不够,可以通过涂油、蜡和涂膜来改善其润湿性,使涂层与原膜分离。但应特别注意湿滑液易吸收废物,工程施工结束后,应尽快将可拆卸的原膜在安装前拆除。

有效的生产和加工速度应根据机器和设备的状况、加工工艺标准、零件的外观等来确定,高速变化率容易导致涂层脱落。当温度较低时,涂层的柔韧性降低,应防止超低温生产和加工。如果工作温度较低,在生产加工前应将原材料加热至所需温度。

What are the quality requirements for color coated plates in the process of processing

Physical property is the key index value to consider formability and the key parameter to determine and adjust manufacturing process. Therefore, physical property should be considered first in production and processing. Pencil hardness, T-bend, impact energy and other index values are closely related to the production and processing characteristics, so they should also be considered. When the appearance of parts is complex and the deformation degree is large, multi pass forming should be selected. If it is formed many times, it will cause excessive deformation and destroy the total iron binding force between the coating and the substrate.
In the process of production and processing, the appropriate gap should be set according to the appearance, deformation characteristics, processing technology standards and other factors, and the coating thickness should be considered when setting the gap. Most coatings can be used as solid lubricants, and the wetting law of most forming processes can be considered. Some architectural coatings can improve the wettability of coatings according to the adjustment secret recipe. If the wettability of the coating is not enough, the wettability can be improved by applying oil, wax and coating film, and the coating can be separated from the original membrane. However, special attention shall be paid to the fact that the wet synovial fluid is easy to absorb waste, and the removable original membrane shall be removed before installation as soon as possible after the completion of the project construction.
The effective production and processing speed should be determined according to the condition of the machine and equipment, the processing technology standard, the appearance of the parts, etc. the high-speed change rate is easy to cause the coating to fall off. When the temperature is low, the flexibility of the coating is reduced, and the ultra-low temperature production and processing should be prevented. If the working temperature is low, the raw materials shall be heated to the required temperature before production and processing.
