In some projects, there will be the phenomenon of the tunnel fireproof coating falling off. This phenomenon directly affects the fire resistance of the substrate. In view of this phenomenon, how to carry out renovation and remedial work is something we need to understand.
The shedding of fire retardant coatings may be a product quality issue, it may also be a problem of construction quality, or it may be due to environmental issues. These problems may lead to certain problems in the construction quality, and some may be due to long-term erosion of the harsh environment, resulting in the appearance of the fire protection coating.
If the tunnel fire protection coating material appears to fall off, it must be resolved for the first time. If the personnel discovers that the phenomenon of shedding has occurred, promptly report it to the superior and set the plan. The following Xiaochuan Xiaobian introduced the entire process, first of all, this requires the purchase of products, if not because of product quality problems directly to buy previously used manufacturers of fire retardant coatings. If it is because of quality problems, it is necessary to use other excellent manufacturers' products; after that, it is necessary to use a professional construction team to carry out the construction work. First, clean up some materials around the fallen parts, and then perform the surface cleaning of the substrate. The surface is cleaned in time, and must be cleaned up. After the cleaning is completed, the next step of the construction work is completed. The cleaning work is very important. It must be done well. After that, the construction work must be started. The construction process must be strictly followed. construction. In the construction process, we must take into account the impact of the construction environment, timely deal with the impact of factors on the construction environment, make necessary preventive measures in order to ensure that in all aspects are more reasonable to carry out construction in order to ensure the entire project Quality; After the construction is completed, it is necessary to protect the finished product. This is also very critical. In the case of materials that have not yet fully dried out, we must choose a good construction environment and prevent protection measures.
Hebei Shengchuan Fireproofing Material Co., Ltd. has a professional construction team, supporting machinery and equipment, and unique construction technology. It will design corresponding optimal construction plans for each site's climate, site conditions, etc., and can guarantee high-quality standardization. Construction, program optimization, reliability, saving, full consultation, follow-up service to ensure one-time acceptance of the project, excellent rate of more than 98%.
Fiberglass Duct Rodder are composed of fiber glass rod which was extruded by fiber glass and high strength resin at high temperature. This type of rod has high tensile strength and flexibility. It was covered by a high density polyethylene engineering plastic as its protect layer(High Density polyethylene (Grade: for the insulating and jacketing of Telecommunication Cables) is used in the outer diameter coating.), which make duct rodder cover sliding on surface, durable, corrosion resistant and has good insulation performance, which make them safe for use in cable occupied duct.
And moving type fiberglass duct rodder will equipped with different size reel according to the length of rod. There are wheels on the reel, which make it convenient for moving.
Features and Benefits:
1-Light weight, durable, resistance to acid, alkali, aging resistant, corrosion resistant.
2-High tensile strength and bending properties, which make it to go through narrow pipes easily.
3-Good temperature adaptability, the product will not soften in hot weather/nor become brittle in cold weather. Its usability will not be affected by temperature.
4-Outer protect layer are made of high density polyethylene engineering plastic, which has good anti-UV capability.
5-Cover was coated with long-term UV-resistant polyethylene.
6-Its surface has the advantage of smooth, wear-resistant and long service life.
7-There are meter marks on the protect layer of duct rodder, which can be used for measuring distance. Marks are printed by professional printing machine, which has the advantage of strong adhesion, clear writing, waterproof, anti-ultraviolet, it can be still clear even after using many times.
8-There are several kinds of colors for the rod for your chosen.
