防火电缆桥架喷涂工艺一般分为喷涂防火漆工艺和喷涂热固性防火粉末工艺。金属防火电缆桥架一般都是金属电缆桥架经过以上防火喷涂工艺加工而成的。下面山东电缆桥架小编给大家具体介绍一下这两种防火喷涂工艺。

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.

喷涂防火漆工艺使用的是涂层不容易燃烧或延缓燃烧的漆，防火漆包括氯化石蜡、氯化橡胶、氯化萘和硼酸锌这些成分，常用来喷涂在电缆桥架和仓库船舶上，当防火电缆桥架所在建筑物起火后，桥架表面的防火漆遇热会产生不能燃烧的气体或气泡，能阻止或延缓桥架板材的燃烧，从而保证防火电缆桥架的电缆能够正常工作一段时间。

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.

喷涂热固性防火粉末工艺使用的粉末为热固性粉末，这种粉末是以热固性合成树脂作为成膜物质，这种物质的特点是用一些较低聚合度的预聚体树脂，在固化剂存在下经过烘烤固化，变为了不能溶化或熔融的质地坚硬的终产物。

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.

当温度在升高时，这种工艺的产物只能分解不能再软化，属于化学变化。这种热固性防火粉末具有较好的流平性、润湿性，能牢固的粘附于电缆桥架表面，并且固化后有较好的装饰性和防腐蚀性。

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.

使用过程防火喷塑电缆桥架在使用过程中，应该注意以下几点：

The following points should be paid attention to during the use of fireproof and plastic sprayed cable tray:

1.在安装前应先对防火喷塑电缆桥架材料、尺寸和形状进行检查，确保防火喷塑电缆桥架完全符合设计要求；

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.防火喷塑电缆桥架安装时，应符合相关安装规范，确保防火喷塑电缆桥架的牢固性和稳定性；

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.防火喷塑电缆桥架安装后，应对桥架及附件进行检查，确保防火喷塑电缆桥架完全符合设计要求；

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.使用过程中，应定期对防火喷塑电缆桥架进行检查和维护，确保防火喷塑电缆桥架持续稳定运行；

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;
