What is fluorocarbon paint construction process of fluorocarbon paint for building exterior walls

General paint is easily contaminated by rain, dust and other pollutants after brushing, and it is very troublesome to clean up. For this reason, people have developed a kind of paint called fluorocarbon paint, fluorocarbon paint has strong corrosion resistance, at the same time, it is not easy to be contaminated, and it has the function of free cleaning, which simplifies the maintenance of the paint to a large extent, and saves a lot of manpower and material resources. Now fluorocarbon paint has been widely used in construction, chemical, mechanical, home decoration and other industries in various fields are widely used, now we come together to understand what is fluorocarbon paint and the construction of fluorocarbon paint construction process.

What is fluorocarbon paint

Fluorocarbon paint refers to fluorine-containing **** polyresin or fluorine olefin and other monomers **** polymer-based film-forming substances, processing, modification, grinding of coatings, referred to as fluorine coatings, in the industry to enjoy the "King of Coatings," known as. Fluorine coatings, compared with general coatings, have excellent properties such as weathering durability, acid and alkali resistance, chemical resistance, heat resistance, cold resistance, self-extinguishing, non-stick, self-lubricating, radiation resistance, etc. It has a service life of 3 times longer than that of ordinary coatings. Its service life is 3 to 5 times that of ordinary paints,

It can be widely used in the fields of construction, industry, aviation, electronics, electrical, mechanical and family daily necessities, wood furniture and so on.

Fluorocarbon paint has just been invented has only been used in non-stick pots, medical, aviation and other fields, did not enter the field of construction. 1965, the United States developed a successful construction of fluorocarbon coatings, fluorocarbon coatings to achieve the commercialization, people see the prospects for fluorocarbon coatings in the field of construction applications. Until 1982, Japan's Asahi Nitrite subsidiary developed a room temperature can be dissolved in aromatic hydrocarbons, lipids, ketones, solvents, room temperature curing fluorine resin, the realization of the construction site site coating fluorocarbon coatings ideal, greatly expanding the application of fluorocarbon coatings.

Compared with traditional paint coatings, it has more excellent light resistance and weather resistance; its quality is light and will not bring heavy burden to the wall, and there is no danger of aluminum composite panel falling. Compared with the traditional aluminum composite panel, it is easier to operate, easy to renovate, not subject to the limitations of the shape of the building,

can be left to the imagination of the designer; the cost is much lower than the aluminum composite panel, and can achieve the same effect.

Fluorocarbon paint product features

1, the exterior wall fluorocarbon paint has extraordinary weather resistance, paint film does not scratch off, does not fade for a long time, life expectancy of up to 20 years.

2, exterior fluorocarbon paint has outstanding salt stain resistance.

3, exterior fluorocarbon paint has strong adhesion and excellent chemical resistance.

4, exterior fluorocarbon paint has excellent stain resistance and scrub resistance.

5, the paint film is soft and elegant, anti-fog flame retardant.

Fluorocarbon paint application range

Fluorocarbon coatings for exterior walls are suitable for high-rise, super-high-rise, villas and other buildings, roofs, highway fences, bridges and other important buildings, as well as a variety of metal surfaces. Fluorine coatings are widely used in various fields of construction, chemical industry, electrical and electronic industry, mechanical industry, aviation and aerospace industry, and household products. After acrylic coatings, polyurethane coatings, silicone coatings and other high-performance coatings,

the highest comprehensive performance of the coating.

Fluorocarbon paint construction process

1, process: grass-roots treatment → scrape flexible putty 1-2 times, sanding → bullet line, compartment, paste tape → rolling elastic hair pulling paint → spraying sealer → spraying intermediate paint → spraying fluorocarbon paint on the exterior wall → local repair

2, grass-roots level treatment:

1). Check the flatness of the wall surface, large protrusions need to be sanded flat, large depressions or holes with cement mortar to fill and sand flat.

2). Large cracks on the wall surface for cutting, and continuous multiple filler high elastic putty, until the wall is flat, putty dry sanding.

3). Use a brush, spatula or sandpaper to remove particles of debris on the wall, and remove the loose cement layer on the wall.

4). After processing requirements to meet the flatness requirements ≤ 2mm.

5). The wall surface to achieve basic cleanliness, no floating dust, no adherence to particulate matter.

3, scraping putty, sanding: scraping flexible putty 1-2 times, sanding and cleaning with a brush.

4, line, grid, tape: according to the design scheme in the color parts of the grid positioning, line, tape.

5, hair pulling: After the tape is pasted, use the professional hair roller on the wall for elastic hair pulling. Requirements: basic uniformity and consistency of the grain.

6, primer spraying:

1). Check whether the putty meets the requirements, there are problems with the place in time to repair.

2). In the completely dry wall (the wall should be dry, wall moisture content of less than 8%) on the spray primer (air pressure in 5-8kg/cm2, waterless spray)

3). Requirements for uniform spraying, no leakage of spraying, the color should be uniform and consistent, no bloom phenomenon, windy (more than six) and rainy days can not be constructed

4). Primer spraying once, spraying finished checking, found that the wall has batch scratch marks or bee's eye phenomenon, must be polished to meet the requirements.

5). Sanding should be 280 mesh or 360 mesh water abrasive sandpaper, sanding should be careful, pay attention to the coating film can not be ground through.

6). Sanding should be dusted, with a rag and other dust generated by sanding on the wall to deal with clean. If the dust removal is not complete, the fluorocarbon paint construction will not be able to achieve a smooth coating film.

7). After the primer is sprayed, the color should be uniform, the luster is uniform, and the surface of the coating film is smooth and free of dust and other stains.

7, paint elastic intermediate paint: according to the design requirements for intermediate paint painting operation. Requirements: even painting, no bottom phenomenon.

8, brush top coat: after the previous procedure is fully dry, configure fluorocarbon paint according to the ratio at the construction site. In the specified time, continuous spraying with a special spray gun, and stir the exterior fluorocarbon paint at any time to ensure that the coating is uniform. Requirements; leveling, uniform thickness, no leakage spray.

9, check the construction quality, local quality problems for repair.

10, surface treatment: before painting the exterior fluorocarbon paint, the surface of the substrate should be clean, dry, flat, firm, no greasy, rust and other debris, the wall water content is less than 8%, Ph value is less than 10, it is recommended to fill in the gaps with exterior putty, and polished smooth; treatment of floating and sinking: can be blown clean with compressed air or clean brush sweep. Old paint film treatment: shoveling with a scraper, filling and sanding flat, or other methods as the case may be.

11, construction methods: exterior fluorocarbon paint is suitable for conventional spraying, brushing, roller coating.

12, the construction temperature: 5 ~ 35 ℃; air relative humidity of less than 75%, to avoid construction in the rain, snow, fog weather, prohibit the exterior fluorocarbon paint and water, alcohol contact.
