pvc护栏防护手段分析。热固性粉末涂料的绝大部分用静电粉末涂装法施工。在锌基重防腐+纯聚酯双涂层技术中, 锌基重防腐粉末涂料层和聚酯粉末涂料层都是采用静电粉末涂装法进行粉末喷涂。比如2006 年3 月的界阜蚌高速公路。
Analysis of protective means of PVC guardrail. Most of the thermosetting powder coatings are constructed by electrostatic powder coating. In zinc based heavy duty and pure polyester double coating technology, zinc based heavy duty powder coating and polyester powder coating are all made by electrostatic powder coating. For example, the expressway in March 2006.
2006 年6 月的安徽合巢芜高速公路等几条高速公路pvc护栏的使用情况来看, 护栏材料颜色一致、表面光洁、防腐性能优良, 受到业主的好评。静电粉末喷涂后的pvc护栏进入烘烤炉进行烘烤, 以使粉末涂料交联固化成膜。
In June 2006, the use of PVC guardrail on several expressways such as Anhui Hefei Wuhu Expressway showed that the guardrail materials had the same color, smooth surface and excellent anticorrosive properties, and were praised by the owners. The PVC barrier after electrostatic powder spraying was baked in a baking furnace to make the powder coating crosslinked and solidified into a film.
锌基重防腐+纯聚酯双涂层高速公路护栏防护技术具有很大的适用性和广泛应用前景。从施工的2004 年5 月的合宁高速公路、2005 年12 月的河南漯周界高速公路。pvc护栏静电粉末喷涂设备是由供粉装置、喷枪、粉末回收设备组成。烘烤:烘烤是成膜的重要步骤。
The protective technology of zinc based heavy anticorrosion and pure polyester double coating on highway guardrail has great applicability and wide application prospect. From the construction in May 2004, December 2005 the Henan Nanjing Expressway Luozhou border highway. The electrostatic powder spraying equipment is composed of powder feeding device, spray gun and powder recovery equipment. Baking: baking is an important step in forming a film.
