What are the ingredients of three cloth and four oil antiseptics

Three cloth and four oil refers to three layers of glass fiber cloth, four times resin composite into FRP anti-corrosion lining, resin types are determined according to the medium, commonly used epoxy resin, vinyl ester resin, unsaturated polyester resin and so on.

The three-cloth four-oil anti-corrosion steel pipe adopts a two-component room temperature curing coating, and the glass cloth is used as a strengthening coating on the surface of the steel pipe to prevent corrosion. It can be used for the anti-corrosion of the outer wall of buried or underwater oil, gas, water and thermal pipelines, and is also suitable for the anti-corrosion of various steel structures, docks, ships, sluices, gas storage tanks, oil refining and chemical plant equipment and the anti-leakage of sewage pools, roof waterproof layers and basement concrete layers.

In the painting of the outer wall of the pipe, it is used in conjunction with the glass fiber cloth wrapping to become a reinforced or extra-reinforced coating, with excellent anti-corrosion performance. The three-cloth and four-oil anticorrosive steel pipe is composed of paint and glass fiber cloth, which can enhance the mechanical properties of the anti-corrosion layer. It has excellent electrical insulation, water permeability resistance, microbial erosion resistance, stray current resistance, heat resistance, and temperature difference resistance.

Three layers of fiberglass cloth four times resin, which means that a layer of resin primer is brushed first, and then cured, according to one cloth and one glue construction, but anti-corrosion should be selected according to the chemical medium contacted. The selection of resin is improper, and the quality cannot be guaranteed, and anti-corrosion is required, please use the user name.

"Three cloths" refers to glass silk cloth, and "four oils" refers to anticorrosive coatings, generally using asphalt.

During construction, it is to brush the asphalt first, and then wrap a layer of glass cloth, and so on three times.

The oil is epoxy coal asphalt paint, the cloth is glass silk cloth, that is, shabu 5 times paint, wrapping three layers of cloth anti-corrosion method to do, this is a relatively old anti-corrosion method, asphalt annihilation paint is polluted to groundwater and soil, the Ministry of Environmental Protection does not advocate this anti-corrosion method, with polypropylene anti-corrosion tape can be replaced, environmental protection, pollution-free, long life, fast, anti-corrosion, materials,

FRP anticorrosive judgment three cloth five oil sleeve quota:

FRP brush asphalt paint once, set of "FRP air duct brush asphalt paint" quota;

The air duct is wrapped with glass wire cloth three times, and the quota of "air duct installation glass wire cloth protective layer" is set, and the engineering quantity is 3 layers;

Brush the glass silk cloth with asphalt paint 4 times, and set the quota of "glass silk cloth surface with asphalt paint", a total of 4 times.

What exactly does the three cloths and five oils in antiseptic refer to?

The oil is epoxy coal asphalt paint, the cloth is glass silk cloth, that is, the anti-corrosion method of shabu 5 times paint, wrapping three layers of cloth, this is a relatively old anti-corrosion method, asphalt paint is polluting to groundwater and soil, the Ministry of Environmental Protection does not advocate this anti-corrosion method, with polypropylene anti-corrosion tape can be replaced, environmental protection is quick, pollution-free, long life, fast, anti-corrosion, materials, FRP anti-corrosion three cloth five oil sleeve quota: FRP brush asphalt paint once, set of "FRP air duct brush asphalt paint" quota; The air duct is wrapped with glass silk cloth three times, and the quota of "air duct installation glass brother cherry glass silk cloth protective layer" is set, and the engineering quantity is 3 layers; Glass silk cloth brush asphalt paint 4 times, set of "glass silk cloth surface brush asphalt paint" quota Xianchang Cong, a total of 4 times.

1. The cloth is glass fiber cloth, and the oil is waterproof ointment. First oil and then cloth, repeat three times, and then oil once, a total of three cloth and four oil.

2. The envelope structure of the building should be slag or section to prevent the infiltration of rainwater, snow water and groundwater; It is necessary to prevent the erosion of moisture, vapor and other harmful gases and liquids in the air; The group chain is divided into a partition structure to prevent the seepage of water supply and drainage. These materials that are resistant to penetration, leakage, and erosion are collectively referred to as waterproofing materials.

First brush the cold base oil, the second step is to brush a layer of asphalt oil, the third step is to wrap a layer of fiberglass cloth, the fourth step is to paint a layer of asphalt oil, the fifth step is to wrap a layer of fiberglass cloth, the sixth step is to paint a layer of asphalt paint, and the seventh step is to paint a layer of oil.

Generally, the conventional design of the pipeline outside the anti-corrosion treatment is one bottom, three oil and two cloth.

The oil is epoxy coal asphalt paint, the cloth is glass silk cloth, that is, the anti-corrosion method of shabu 5 times and the three-layer cloth is wrapped, this is a relatively old anti-corrosion method, asphalt paint is polluted to groundwater and soil, the Ministry of Environmental Protection does not advocate this anti-corrosion method, and the polypropylene anti-corrosion tape can be replaced, environmental protection, pollution-free, long life, rapid growth, anti-corrosion, materials

The so-called three cloth and five oil is a process of external anti-corrosion of steel pipes.

Specific method: The processing of the outer anti-corrosion layer of the steel pipe must be in strict accordance with the design requirements and relevant national standards. Rust removal must reach the level, the primer must be completed within 2 hours after the rust is removed, and the anti-corrosion layer of three cloths and five oils can be made only after the primer is dry. Each processing of a glass cloth, brush an epoxy coal asphalt, must wait for it to dry before the second anti-corrosion, otherwise in the transportation process and installation process is very easy to damage the anti-corrosion layer, and the anti-corrosion layer directly affects the service life of the directly buried pipeline.

After the anti-corrosion layer is completed, its thickness and adhesion must be sampled and inspected according to the regulations, so that the appearance is smooth, no wrinkles and bubbling, and the glass cloth mesh is all filled with paint. Finally, the electric inspection of the anti-corrosion layer is carried out with an electric cremation leak detector, and the voltage of leak detection is 3000 volts.

The four oils and three cloths here refer to the requirements for strengthening the level when using petroleum asphalt to carry out anti-corrosion protective layer on the outer wall of the pipeline. The total thickness of the anti-corrosion layer, construction structure technology: asphalt primer + asphalt + glass cloth + asphalt + glass cloth + asphalt + glass cloth + asphalt + polyvinyl chloride industrial film (four oil and three cloth).

Promote the construction of anti-corrosion layer using polyethylene adhesive tape, reinforced construction structure process: primer + anti-corrosion adhesive tape (inner belt) + protective adhesive (outer belt) or primer + anti-corrosion adhesive tape, anti-corrosion total thickness.

The cloth is fiberglass cloth, and the oil is waterproof ointment. First oil and then cloth, repeat three times, and then oil once, a total of three cloth and four oil.

The envelope of the building should prevent the infiltration of rainwater, snow water and groundwater; It is necessary to prevent the erosion of moisture, vapor and other harmful gases and liquids in the air; The separating structure should prevent the seepage of water supply and drainage. These materials that are resistant to penetration, leakage, and erosion are collectively referred to as waterproofing materials.

It is to make waterproof bar, the cloth is glass fiber cloth, and the oil is waterproof ointment. First oil and then cloth, repeat three times, and then oil once, a total of three cloth and four oil.

The cloth is fiberglass cloth and the oil is resin.

Brush a layer of oil and paste a layer of cloth, and then brush oil and then paste cloth, in general, the anti-corrosion is strengthened into three oil and two cloths, thinking that anti-corrosion materials should be used on it, such as epoxy cement or furan cement to paste acid-resistant bricks, and the gaps are tightly hooked when pasting, and some projects require 5 cloth and 6 oil.
