2. Quality of the surface treatment
有机硅耐热面漆 Silicone heat resistant finish The surface of the equipment shall be strictly treated according to the (USA) Steel Structure Paint Committee SSPC (Steel Structures Painting Council, USA) or other equivalent standards, and the paint shall be properly selected and the coating process shall be carefully followed.
The quality of surface treatment must be strictly inspected, and shall not be painted without meeting the requirements of the standard.
DreamTherm 400 topcoatPainting application shall comply with the requirements specified herein.
3.有机硅耐热面漆 Silicone heat resistant finishEnvironmental restrictions
If the equipment is painted at the Contractor's plant, the Contractor must ensure that good surface cleaning, air dust free, good ventilation and lighting, and proper temperature and humidity conditions exist.
For materials conducted in the open air, DreamTherm 400 topcoat Work, do not paint in bad weather conditions, such as high humidity, windy weather. Unless appropriate measures are taken to overcome these difficulties.
During surface treatment and painting, the treated surface temperature is at least 3 C above the surrounding air dew point.
In handDreamTherm 400 topcoat During construction, the temperature of the treated surface shall not be lower than 7 C and not higher than 38 C.
Moisture and humidity limitation
DreamTherm 400 topcoatDo not in the sun, exposure and rain, snow and fog;DreamTherm 400 topcoatDo not apply paint in smoke or in relative humidity when paint condenses on the metal surface due to changes in metal temperature and ambient temperature.
Unless otherwise specified and recommended by the paint manufacturer, painting shall be performed at relative humidity lower than 85%.
All surfaces are under construction ofDreamTherm 400 topcoat shall be completely dry before and within 24 hours after painting.
Time slicing
Generally, the primer should be applied to the sandblasting treatment area within 4 hours after the completion of the sandblasting treatment. After this time, the surface should be treated for a second time. This time limit may be modified to more than 4 hours or less depending on the temperature and humidity control implemented. The main standard shall be no rust film on the surface before primer. If any rust coating is formed, the surface shall be sandblasted before priming.
The interval time of coating should be strictly controlled according to the coating process.
Temperature limitation
Unless otherwise specified and suggested by the paint manufacturer, in general, the DreamTherm 400 topcoat Painting shall be performed from 10℃ to 32℃. Paint should not be applied when the ambient air temperature is below 5℃ or when the temperature is expected to drop to 0℃ before the paint is dry.
Steel at temperatures above 50℃ shall not be painted unless specially prepared paint is applied at this temperature. When steel is painted in hot climate, precautions should be taken to ensure obtaining the required dry film thickness.
The welding part can only be painted after 72 hours of welding.
Construction can be carried out only when the substrate temperature is above 3℃ above the dew point. Do not paint when the treated surface is exposed.
Cleaning
DreamTherm 400 topcoat Painting and paint film drying process should keep the surrounding air clean, and should not be painted in a dust environment.
4. 有机硅耐热面漆 Silicone heat resistant finishPaint deployment
DreamTherm 400 topcoatPaint shall be prepared strictly according to the product instructions of the paint manufacturer.
The strictly check the should be of inspected, unqualified and expiredDreamTherm 400 topcoatPainting shall not be used for painting. Before use, the paint must be mixed and fully mixed according to the regulations to make it fully mixed.
In layered coating, the color of each layer shall be maintained with enough contrast to check whether the surface is completely covered.
5. 有机硅耐热面漆 Silicone heat resistant finishPainting and brush method
DreamTherm 400 topcoatHigh pressure without air spraying method, brush coating or compressed air spraying construction method can also be used.
Brush coating
Brush coatingDreamTherm 400 topcoat, make paint brush dip in have right amount of coating, distribution is in quite be coated inside the surface range, be extended horizontally first, then longitudinal straighten out, make coating distribution evenly. Can also be the first vertical extension, and then horizontal rationalization, step by step, do not omit.
Compressed air spraying:
Compressed air spraying is the use of compressed air to attract (or compress) the coating from the pot to the spray gun. At 0.2 ~ 0.5 Mpa, the coating mixes the air with the spray and sprays on the coated surface to get an evenly distributed coating.
The coating used for compressed air spraying is thinner than the brush and roller coating, so some diluent needs to be added to the general coating.Airless spraying
High pressure airless spraying usually uses compressed air operation to drive the high pressure pump, the paint is inhaled and pressurized to 10 ~ 25 Mpa, through the high pressure hose and spray gun, and finally through the olive-shaped nozzle. When the paint leaves the nozzle, the atomization into very fine particles, sprayed to the coated surface, forming a uniform film.
6.Other requirements
In order to ensure the thickness of the film of welds, edges, edges and corners, a large area of gas spraying DreamTherm 400 topcoatbefore,preit with a brush.
DreamTherm 400 topcoatDuring pneumatic spraying, the operator shall measure the wet film thickness gauge at any time to controlDreamTherm 400 topcoatpaint film thickness,if manually painted, the number of coating channels should be increased accordingly to ensure that the specified thickness of paint film.
ApplicationDreamTherm 400 topcoatshould use the first up and down after the left and right, or the first left and down after the vertical and horizontal spraying method, so that the paint film smooth and smooth, uniform thickness.
Paint shall be done with brushes of the right specification, except for use of painting equipment or drum.
When spraying equipment is used, the painting equipment shall always be precise and fully controlled to prevent damage to adjacent surfaces. When spraying with the spray gun, the operation rules of the spray gun must be strictly observed, and the spray gun shall not be painted outdoors in rain, snow, fog and windy days.
