Zhengzhou high-altitude engineering maintenance — aluminium preservative company plumbing chimneys for preservation: technical requirements for coating
1 paint construction
1. 1 the paint is constructed in a rolling manner。
1. 2 during the construction of the preservative coating, the wall and ambient temperature shall be greater than +5 °c, with no requirement for humidity。
1. 3 the drying of coatings uses natural drying, with an interval of 12-24 hours for each layer. During the drying of the coating, the surrounding environment should be kept clean to prevent effects such as dust, rain, water and touching。
1. 4 large area painting shall be preceded by a partial painting。
2. Painting requirements
2. 1 bottom-cutting requirements:
(1) bottom coating material, which controls the viscosity, density, thinness of the material, shall be fully broken in exchange, so that the paint colour and viscosity are evenly aligned。
(2) the paint should be painted in the same direction and be fully integrated。
(3) painting shall be done in accordance with the principles of in-service, short brushing and shall prevent the brush belt from being painted too much and falling。
(4) upon completion of the painting, a time gap should be maintained to prevent a second run-through before drying, which may result in a frowning of the paint stream and lower quality. (5) after drying up, do it again, and the direction of the second dosage should be vertically in the direction of the dosing, so that the thickness of the paint sheet is even。
3. Painted:
(1) the paint shall be prepared in such a way that the colour shall be fully consistent, the rare material made shall be suitable, and the paint shall be fully mixed and the colour shall be kept even before it is used. Its viscosity and density shall be covered with no fall and no brushing. (2) the paints shall be continuously mixed and painted in the same manner and direction as the above processes。
(3) requires that the overall colour of the coating be uniform and that there be no fluids, no hangs, no leaks, no stains, etc。
4. Painting works
(1) the paint should not be too deep and the general brushing should not be more than half its length, and the paint should immediately be hit on both sides of the structure of the steel so that the paint enters the end of the brushing。
(2) the varnish shall be moderately plattered, and the paint on the back shall be drained from the upper half of the varnish section. Paint brushes come to the head and then they are brushed from the top down, draining the paint to the front. There is a gap between brushes, usually 5cm-6cm。
(3) the varnish shall be swiped and swiped with the top of the paint, and the paint shall be smooth and smooth. The horizontal surface shall be painted in the direction of the light. In order to avoid scarring, the painted fragments should move frequently when connected, not always in one part。
(4) when multiple layers are painted, the upper layer is dry and then the lower layer of paint is painted, and the layer should combine closely and without layering。
Zhengzhou high-air engineering repair-aluminium preservative company is an engineering operation that requires technical and safety measures. The removal of chimneys should ensure the safety of personnel, avoid damage to building structures, carefully manage exhaust gases, maintain stability and balance, and be sensitive to fire safety. Specific construction methods include chimney-directed and manual demolition. Directed demolition involves measuring the centre of the chimney at its base, measuring the width of the open hole, then opening holes along the drawn line, and lighting the woodboard in the right place to dump the chimney in the intended direction. Manual demolition requires construction personnel to climb high above the top of the chimney, use demolition tools to carry out demolition and ensure that safety measures are in place during the demolition process。
Zhengzhou high-altitude engineering repairs-aluminium preservative company, inc., causes rust in paint paints from the scrawl-painted paint of the chimneys:
1. Fracks of water through the paint membrane, pore or bump to the surface of the steel plate;
2. The stains were not removed before the coating, and special attention should be paid to rusted points and welded areas;
3. Contaminated surfaces of steel before spray paint, such as handprints, which leave their own dry water trails on the surface, which are not properly treated and painted in a timely manner;
4. Deficiencies such as incomplete coatings, needle holes, leaks, such as some cracks, welds not painted, e. G. Unsealed;
5. Poor use of the environment, such as high temperature, high humidity and erosion of corrosive media;
6. No rust-proof base paints were sprayed and paints were sprayed directly after repairing the deer parts。
