膜结构车棚的防护要注意什么?
1、镌刻滚筒涂层法。刮刀涂层法和滚筒涂层法的连结,外貌崎岖的镌刻滚筒的凸部上附有的涂敷液被刮刀刮掉,凹部里的涂敷液被定量转移到膜布局车棚基布上,二氧化钛膜质料的涂层即是采取此方法加工的。
1. Engraved drum coating method. The connection between the scraper coating method and the drum coating method involves scraping off the coating liquid attached to the convex part of the rugged engraved drum with the scraper, and quantitatively transferring the coating liquid in the concave part to the film layout car shed substrate. The coating of titanium dioxide film material is processed using this method.
2、刮刀涂层法。用刮刀在膜结构基布上涂敷一定量的涂敷液,涂层的厚度由刮刀与基布之间的间隙来决定。用此方法也可加工薄型材料。并且,用此方法能够对膜材料的正反两面涂敷不同材质的涂层。
2. Scraper coating method. Apply a certain amount of coating solution on the membrane structure substrate with a scraper, and the thickness of the coating is determined by the gap between the scraper and the substrate. This method can also be used to process thin materials. Moreover, this method can be used to apply coatings of different materials on both sides of the membrane material.
3、滚筒涂层法。用数个滚筒将涂敷液边转移边涂敷在膜结构车棚基布上。
3. Roller coating method. Use several rollers to transfer the coating liquid edge and apply it onto the membrane structure carport substrate.
4、焊接的位置四周5m之内不得存在易燃、易爆物品。焊工高空作业时要戴平安带,随身工具及焊条均应放在专门的皮袋中。
4. There must be no flammable or explosive materials within 5m around the welding location. Welders should wear safety belts when working at heights, and their personal tools and welding rods should be placed in specialized leather bags.
5、辊筒法。用加热辊筒将涂敷液辊轧成薄膜,经几个辊简将涂层薄膜与膜布局车棚基布连结而成。用此方法能够进行较厚的涂层加工,并且能够调处涂层厚度。
5. Roller method. Roll the coating liquid into a thin film using a heating roller, and connect the coating film with the film layout of the car shed substrate through several rollers. This method can perform thicker coating processing and adjust the coating thickness.
6、为了预防弧光辐射焊工,需要佩戴防护面罩(内镶滤光玻璃)。在公共的地方焊接,须装配挡光屏。
6. In order to prevent arc radiation from welding, it is necessary to wear a protective mask (with filter glass inside). When welding in public areas, a light blocking screen must be installed.
