厂家揭示几类环氧地坪漆涂装方法介绍

2018-10-23 12:09:20 常州市星火铝艺制品有限公司 阅读

环氧地坪漆合理的涂装方法关系到环氧地坪漆的涂装质量、生产批量、涂装的经济性等技术经济效益问题。如选择不当,即使有了性能和品质优良的涂料、良好的地坪涂装环境条件、完善适宜的设备工具、技艺高超的地坪漆涂装队伍、现代化的组织管理也不可能达到环氧地坪漆产品涂装预期日的,甚至会造成工期的延误及原材料、财力、物力、能源的损失和不必要的浪费等。

Reasonable coating method of epoxy floor paint is related to the coating quality, production batch, coating economy and other technical and economic benefits. If improper selection is made, it is impossible to achieve the anticipated coating date of epoxy floor paint products, even if there are coatings with excellent performance and quality, good environmental conditions for floor painting, perfect suitable equipment and tools, skilled floor paint painting team and modern organization and management, which may even result in delay of construction period and raw materials. Loss of financial resources, material resources, energy and unnecessary waste. 选择地坪漆涂装方法需要考虑的因素很多,应根据地坪漆涂装的使用环境条件,地坪漆涂膜质量要求,地坪漆涂料的性能、用途和涂装特点,地坪漆涂膜层次,地坪漆涂膜厚度,地坪漆涂装产品的基材(材质)、形状和尺寸,地坪漆涂装前表面状况及预处理方法,环氧地坪漆涂装必备的设备及工具(包括现有设备工具和需要添置的设备工具),地坪漆涂装产品的批次,地坪漆涂料干燥方法及设备条件,地坪漆涂装环境条件和环保设施,组织机构,地坪漆涂装技术水平等进行合理选择。

There are many factors to be considered in selecting the coating method of floor paint. It should be based on the environmental conditions, the quality requirements of the coating, the performance, use and characteristics of the coating, the coating layer, the coating thickness, the substrate (material), shape and size of the coating products, and the floor. Surface condition and pretreatment method before painting, equipment and tools necessary for epoxy floor paint painting (including existing equipment and tools and additional equipment tools), batches of floor paint painting products, drying methods and equipment conditions of floor paint, environmental conditions and environmental protection facilities, organization, floor paint coating Install technical level and make reasonable choice.

第一类、刷涂和滚涂是大多数地坪漆涂料都适用的最原始、最简单的涂装方法,适合涂装各种形状的物体。滚涂时,环氧地坪漆可以容易地渗透到地坪表面的细孔里,因此在地坪表面有较强的附着力。刷涂用到的工具有各种毛刷、砂纸、刮子等,价格便宜,适应性好。其缺点是纯手工操作,生产效率低,劳动强度大,表面平整性较差。

First, brushing and rolling are the most primitive and simplest methods of painting that most floor paint coatings can apply to objects of various shapes. Epoxy floor paint can easily penetrate into the pores of the floor surface during rolling, so it has strong adhesion on the floor surface. The tools used for brushing are various brushes, sandpaper, scrapers, etc., which are inexpensive and adaptable. Its disadvantage is purely manual operation, low productivity, high labor intensity and poor surface smoothness.

第二类、喷涂是一种普遍使用的工业化涂装方法,其原理是将地坪漆喷涂成细小的雾滴并送到工作表面,具有地坪漆涂层质量均匀、工业化生产效率高的特点。喷涂的缺点是地坪漆的损耗率高,溶剂大量挥发,危害施工人员的身体健康,对环境亦有较大的影响。目前常用的方式有压缩空气喷涂、高压无气喷涂、混气喷涂、旋杯喷涂等。

The second type, spraying is a commonly used industrial coating method, its principle is to spray floor paint into small droplets and sent to the working surface, with the floor paint coating quality uniform, high industrial production efficiency characteristics. The disadvantage of spraying is that the loss rate of floor paint is high, a large number of volatile solvents, harmful to the health of construction personnel, and has a greater impact on the environment. At present, the commonly used methods are compressed air spraying, high pressure airless spraying, air mixing spraying, rotary cup spraying and so on.

第三类、电泳法即电沉积涂漆,是将被涂工件作为一个电极浸在水溶性涂料的漆槽中,通直流电使涂料沉积在工件表面形成致密涂层。该过程同时包含了电泳、电解、电沉积和电渗析四个物理过程。由于地坪漆树脂在水中离解的粒子所带正负电荷的不同,电泳又可分为阳极电泳和阴极电泳两种。电泳涂装效率高,可大批量生产,节省资源,危害小,地坪漆涂层均匀一致、附着力强,允许钣金加工形状复杂的工件。电泳法的缺点是涂膜较薄、设备复杂、投资高。

The third type, electrodeposition coating, is to be coated workpiece as an electrode immersed in a water-soluble paint bath, through direct current to make the coating deposited on the surface of the workpiece to form a dense coating. The process includes four physical processes: electrophoresis, electrolysis, electrodeposition and electrodialysis. Electrophoresis can be divided into anodic electrophoresis and cathodic electrophoresis because of the different positive and negative charges of the particles dissociated from the floor paint resin in water. Electrophoretic coating has high efficiency, can be mass-produced, save resources, less harm, floor paint coating uniform, strong adhesion, allowing the processing of complex shape workpieces. The disadvantage of electrophoresis is that the coating is thinner, the equipment is complex and the investment is high.

第四类、静电喷涂法利用高压静电场进行喷涂,生产效率高,可连续自动化生产,环氧地坪漆涂层质量均匀,用于大规模的生产,但缺点是不易喷涂到死角,劳动保护性差。

Fourth, electrostatic spraying method uses high voltage electrostatic field for spraying, high production efficiency, continuous automatic production, epoxy floor paint coating uniform quality, used for large-scale production, but the shortcomings are not easy to spray to the dead corner, poor labor protection.
