Fluorocarbon powder coating is a new type of temperature resistant coating that can greatly improve the weather resistance of building surfaces. In recent years, it has been widely promoted by new coating processes both domestically and internationally, especially fluorocarbon coatings, which have been widely used in the fields of building exterior wall protection, decoration, and interior material coating, and have become a popular new type of coating product.
At present, fluorocarbon coatings are applied in building exterior wall protection, decoration, and interior material coating. In order to ensure coating quality, relevant national and local regulations require compliance. This article will focus on the specifications for spraying fluorocarbon coatings on curtain walls.
1、 Construction quality
The curtain wall spraying project should follow the following principles in construction quality: first, the on-site environment should meet national requirements, and outdoor construction should be carried out in accordance with relevant national quality requirements to ensure painting quality; Secondly, the construction ground should be flat, with local protrusions not exceeding 2mm and no obvious potholes or sinkholes; Once again, it is strictly prohibited to purchase inferior materials for the sleeve. The spacing should comply with regulations, and the surface should be smooth and flat without any scratches or spots; Finally, the joints of different materials should be strictly inspected, and there should be no obvious gaps at the joints. The coating thickness at the joints should be uniform.
2、 Selection of Fluorocarbon Coatings
Fluorocarbon coatings require high construction quality, so you should pay attention to the selection of fluorocarbon coatings. Firstly, fluorocarbon coatings should be selected according to different construction environments, which require different temperature tolerance ranges; Secondly, fluorocarbon coatings should be selected based on the material and lifespan of the construction object, especially in cases of sudden environmental changes; Finally, fluorocarbon coatings should choose products that comply with national standards, are safe, healthy, and have stronger effectiveness to ensure normal construction.
3、 Construction preparation
Before construction, the following work should be fully prepared: first, check the construction site environment to see if there are any sources of pollution; Secondly, it is necessary to check whether the construction site and grassroots are cleaned up; Then, check if the construction tools and equipment are complete; Finally, it is necessary to inspect the construction materials to ensure that the materials used during the process are qualified.
4、 Spray painting construction
During construction, the following precautions should be taken: firstly, the construction case should fully include the construction technical requirements, operation steps, and construction techniques; Secondly, during construction, construction management should be strengthened to ensure that each employee of the construction team implements a unified construction safety system; Once again, attention should be paid to the proper mixing of coatings, temperature requirements, and construction techniques; Finally, the construction results should be checked to ensure that the quality meets the regulatory requirements.
5、 Coating
The joint coating operation during construction is a special construction project, and different quality performances will have a great effect. Therefore, the construction unit proposes the following requirements here: first, smooth the joint coating, pay attention to the coordination of upper and lower materials, and ensure the uniformity of the texture at the joint coating; Secondly, smooth the joints and joints with a gypsum layer to ensure that there are no damages or scratches at the joints; Finally, fill the gaps at the junction with concrete slurry and ensure a deep coverage.
