防污闪硅橡胶是具有RTV工艺特性的特种功能的液态涂料,而真正具有防污闪功能的却是其固化后的涂层。液态涂料转化为固化涂层的过程,即喷涂施工,显然是防护质量的重要一环。现行标准中对施工的规范性条款制订的较少,加之施工队伍参差不齐,因此,每个1次现场喷涂形成的涂层质量不尽相同。通过多年的现场监管实践,总结出防污闪硅橡胶喷涂施工中必须管控的关键节点,从而提高喷涂施工的过程质量和最终涂层质量。 相似文献

In electrostatic powder coating, using a frictional charger, a serious problem is the poor charging characteristics of powder paint. In order to overcome this problem, the authors have investigated a new system composed of a plasma generator and a frictional charger. The results obtained for two kinds of polyester powder paints showed that the plasma has a strong effect on the characteristics of frictional charging in powder paint; the frictional charge was more than five times as large as that without plasma effects 相似文献

The purpose of this work was to develop methods for painting insulating surfaces by the conventional electrostatic painting technique used to coat conducting samples. This technique is not applicable to insulators since the charges carried by the paint accumulate on insulating targets, thereby preventing a proper coating. A detailed investigation of the decay of charges deposited on insulators by a corona discharge simulating the charged paint has confirmed that a grounded counterelectrode (CE) on the back face of the sample speeds up the decay and that the better the contact, the faster the decay. Because a material CE with proper contacts is inconvenient for painting in production configuration, it was suggested that ionized air might behave as a satisfactory CE. Several ionizers have been tested, and good coatings have been obtained, provided that the flows of paint and ionized air are well separated. The possibility of self-creation of ionized air by the voltage of the early paint deposit has also been successfully tested 相似文献
