Why should cables be painted with fireproof paint? How do I brush it?

Cable fire protection coating is a kind of fire protection coating, according to the national standard "GB cable fire protection coating", cable fire prevention coating refers to the surface of the cable (such as rubber, polyethylene, PVC, cross-linked polyethylene and other materials as conductors and sheaths) surface, with fire flame retardant protection and a certain decorative role of fire protection paint.
power plants, industrial mines and other places due to high temperature rise will cause the cable load to decrease, or because the strength of the insulation significantly reduced short circuit and cause fire accidents. Cable fire protection coating is a very effective measure to prevent the spread of cable fires

should I paint a fireproof coating?
first, the use of cable fire protection coatings on cables ensures that cables are not flammable or flammable in flame and remain operational for a certain period of time. After the cable fire prevention coating is affected by fire, it can form a carbonized layer to prevent the fire from burning inland, and can play a role in protecting the cable line.
, brushing cable fire protection coatings is more energy-efficient and more convenient to construct than using other protective measures. Cable fire protection coating because of the thickness is small, good heat dissipation, according to the experiment, the impact on the cable load flow is very small, negligible. When the power cable is fully installed in the fire-proof tank box, or in the fire-proof bridge, the power cable load flow will decrease. Therefore, in the project, the application of fire-resistant paint fire-resistant coatings than the application of slot boxes, fire-resistant bridges in the low energy consumption, and reduce the cost of the project, more economical.
, the coating of cable fire protection paint is an effective way to prevent the vertical spread of fire.
cables are generally laid in pipeline wells, pipeline wells should produce chimney effects in fire, especially in high-rise buildings. If the cable does not take fire prevention measures, it is easy to spread the fire to expand, forming a large area of combustion. Therefore, the flame retardant performance of the cable is related to the spread of the fire.
do you paint fireproof paint?
first, before the construction of fire-resistant coatings should be the cable surface of floating dust, oil, debris and other cleaning, polishing clean, until the surface is dry before the construction of fire-resistant coatings.
second, the construction of this product using spraying, brushing and other methods, when used should be fully stirred evenly, when the paint is slightly thicker, can be diluted with the appropriate amount of tap water, to facilitate spraying is appropriate.
, the construction process and before the coating is dry, should be waterproof, anti-riot sun, anti-pollution, anti-movement, anti-bending, if there is damage and timely repair.
Fourth, for plastic, rubber skin wire and cable, is generally directly painted more than 5 times, the thickness of the coating is 0.5-1mm, about 1.5kg / m2, for the packaging of oil paper insulation cable, should be wrapped in a glass wire cloth, and then painted, if outdoor or wet environment construction, should be added to the cover varnish.
