防火電纜橋架噴涂工藝一般分為噴涂防火漆工藝和噴涂熱固性防火粉末工藝。金屬防火電纜橋架一般都是金屬電纜橋架經(jīng)過以上防火噴涂工藝加工而成的。下面山東電纜橋架小編給大家具體介紹一下這兩種防火噴涂工藝。

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.

噴涂防火漆工藝使用的是涂層不容易燃燒或延緩燃燒的漆，防火漆包括氯化石蠟、氯化橡膠、氯化萘和硼酸鋅這些成分，常用來噴涂在電纜橋架和倉庫船舶上，當防火電纜橋架所在建筑物起火后，橋架表面的防火漆遇熱會產(chǎn)生不能燃燒的氣體或氣泡，能阻止或延緩橋架板材的燃燒，從而保證防火電纜橋架的電纜能夠正常工作一段時間。

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.

噴涂熱固性防火粉末工藝使用的粉末為熱固性粉末，這種粉末是以熱固性合成樹脂作為成膜物質(zhì)，這種物質(zhì)的特點是用一些較低聚合度的預聚體樹脂，在固化劑存在下經(jīng)過烘烤固化，變?yōu)榱瞬荒苋芑蛉廴诘馁|(zhì)地堅硬的終產(chǎn)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.

當溫度在升高時，這種工藝的產(chǎn)物只能分解不能再軟化，屬于化學變化。這種熱固性防火粉末具有較好的流平性、潤濕性，能牢固的粘附于電纜橋架表面，并且固化后有較好的裝飾性和防腐蝕性。

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.

使用過程防火噴塑電纜橋架在使用過程中，應該注意以下幾點：

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

1.在安裝前應先對防火噴塑電纜橋架材料、尺寸和形狀進行檢查，確保防火噴塑電纜橋架完全符合設計要求；

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.防火噴塑電纜橋架安裝時，應符合相關安裝規(guī)范，確保防火噴塑電纜橋架的牢固性和穩(wěn)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.防火噴塑電纜橋架安裝后，應對橋架及附件進行檢查，確保防火噴塑電纜橋架完全符合設計要求；

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.使用過程中，應定期對防火噴塑電纜橋架進行檢查和維護，確保防火噴塑電纜橋架持續(xù)穩(wěn)定運行；

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;
