The spraying process of fireproof cable tray is generally divided into the spraying process of fireproof paint and the spraying process of thermosetting fireproof powder. Metal fireproof cable tray is generally made of metal cable tray through the above fireproof spraying process. The following is a brief introduction of the two fire protection spraying processes for cable tray in Shandong.
The fireproof paint spraying process uses the paint whose coating is not easy to burn or retards combustion. The fireproof paint includes chlorinated paraffin, chlorinated rubber, naphthalene chloride and zinc borate, which are commonly used for spraying on cable tray and warehouse ships. When the building where the fireproof cable tray is located catches fire, the fireproof paint on the bridge surface will generate incombustible gas or bubbles when heated, which can prevent or retard the combustion of the bridge plate, So as to ensure that the cables of the fireproof cable tray can work normally for a period of time.
The powder used in the process of spraying thermosetting fireproof powder is thermosetting powder, which is a film forming material made of thermosetting synthetic resin. The characteristic of this material is to use some low degree of polymerization prepolymer resin, which is baked and solidified in the presence of a curing agent to become a hard end product that cannot dissolve or melt.
When the temperature rises, the products of this process can only decompose and cannot be further softened, belonging to a chemical change. This thermosetting fireproof powder has good leveling and wettability, can firmly adhere to the surface of cable tray, and has good decorative and anti-corrosion properties after curing.
The following points should be paid attention to during the use of fireproof and plastic sprayed cable tray:
1. Before installation, the material, size and shape of the fireproof plastic sprayed cable tray shall be comprehensively checked to ensure that the fireproof plastic sprayed cable tray fully meets the design requirements;
2. The installation of fireproof plastic sprayed cable tray shall comply with relevant installation specifications to ensure the firmness and stability of fireproof plastic sprayed cable tray;
3. After the installation of fireproof plastic sprayed cable tray, the bridge and accessories shall be comprehensively inspected to ensure that the fireproof plastic sprayed cable tray fully meets the design requirements;
4. In the process of use, the fireproof plastic sprayed cable tray shall be inspected and maintained regularly to ensure the continuous and stable operation of the fireproof plastic sprayed cable tray;
