今天來看看檢測電纜橋架質量的具體內容，任何產品只有符合國家規定，檢測通過才能上市，電纜橋架也不例外。今天我們整理相關資料為您介紹檢測濟南電纜橋架質量的具體內容。

Today, let's take a look at the specific content of testing the quality of cable tray. Any product can only be listed if it meets the national regulations after passing the testing, and cable tray is no exception. Today, we collate relevant materials to introduce the specific content of testing the quality of Jinan cable tray.

1、外觀檢查

1. Visual inspection

所有部位用目測法檢查,不允許有下列缺陷:氣泡,耐蝕層表面允許大氣泡直徑為5mm,每平方米直徑不大于5mm的氣泡小于3個時,可不予修補,否則應將氣泡劃破修補;裂紋,耐蝕層表面不允許有深度大于0.5mm的裂紋,增強層表面不允許有深度大于2mm的裂紋;凹凸(或皺紋),耐蝕層表面光滑平整,增強層的凹凸部分厚度不大于厚度的20%;反白,耐蝕層不允許有返白區,增強層返白區大直徑為50mm;其它,玻璃鋼橋架層間粘結應牢固,不允許有分層、脫層、層纖維裸露、樹脂結節、異物夾雜、色澤明顯不勻等現象。

All parts shall be inspected by visual inspection, and the following defects are not allowed: bubbles. The diameter of large bubbles on the surface of the corrosion resistant layer is allowed to be 5 mm. When there are less than 3 bubbles with a diameter of no more than 5 mm per square meter, they can not be repaired, otherwise they should be scratched and repaired; Cracks, no cracks with a depth greater than 0.5mm are allowed on the surface of the corrosion resistant layer, and no cracks with a depth greater than 2mm are allowed on the surface of the reinforcement layer; Concave convex (or wrinkle), the surface of the corrosion resistant layer is smooth and flat, and the thickness of the concave convex part of the reinforcement layer is not more than 20% of the thickness; The back white area is not allowed in the anti corrosion layer and the large diameter of the back white area in the reinforcement layer is 50mm; For others, the bonding between layers of glass fiber reinforced plastic bridge shall be firm, and no layering, delamination, layer fiber exposure, resin nodule, foreign matter inclusion, obvious uneven color, etc. are allowed.

2、材料力學性能及樹脂含量測量

2. Measurement of mechanical properties and resin content of materials

在玻璃鋼橋架制做的同時,按相同原材料和工藝條件制作一定數量的試樣或在已到貨的橋架中取樣進行材料力學性能和樹脂含量的測試。測試工作須按我國有關的國家標準進行,數據結果應符合產品的設計要求。

At the same time of making glass fiber reinforced plastic cable tray, a certain number of samples shall be made according to the same raw materials and process conditions, or samples shall be taken from the arrived cable tray to test the material mechanical properties and resin content. The test shall be carried out in accordance with the relevant national standards of China, and the data results shall meet the design requirements of the product.

3、玻璃鋼橋架材料表面硬度的測定

3. Determination of surface hardness of glass fiber reinforced plastic bridge materials

材料表面硬度的大小一方面表明了樹脂的固化度,另一方面可反映材料的其它物理化學性能,硬度的測定用巴柯爾硬度計進行。

On the one hand, the surface hardness of the material indicates the curing degree of the resin, on the other hand, it can reflect other physical and chemical properties of the material. The hardness is measured with a Barcol hardness tester.

4、玻璃鋼橋架各幾何尺寸及壁厚測量

4. Measurement of geometric dimensions and wall thickness of glass fiber reinforced plastic bridge

玻璃鋼橋架出廠前或到廠后,各幾何尺寸及壁厚等應該用相應精度要求的鋼制量具進行詳細測量,有不合要求者應降級使用或報廢。此外,還需有橋架的加載試驗以及耐蝕性浸泡試驗等,一般由制造廠家進行或與用戶共同完成。

Before leaving the factory or after arriving at the factory, the geometric dimensions and wall thickness of the glass fiber reinforced plastic bridge shall be measured in detail with steel measuring tools with corresponding accuracy requirements. Those unqualified shall be degraded for use or scrapped. In addition, the loading test and corrosion resistance immersion test of the cable tray shall be conducted by the manufacturer or jointly with the user.
