Fire safety defense line: The importance of GB/T5725 safety net flame retardant equipment in the construction industry

The construction industry is the main application area of safety nets. Once a fire occurs during high-altitude operations, safety nets with substandard flame retardancy will quickly burn, exacerbating the spread of fire and threatening the safety of construction personnel. The application of GB 5725 safety net flame retardant detection equipment developed and produced by Xinsheng Zhuorui Technology is an important measure to strengthen the fire safety defense line of construction.

At construction sites, there are many scenarios such as welding operations and open flame operations, which can easily generate sparks. If the flame retardant performance of the safety net is poor, sparks may ignite upon contact, leading to fire accidents. The safety net detected by GB 5725 equipment can control the ignition and smoldering time within the range specified by the standard. Even if it comes into contact with flames, it can quickly extinguish and will not continue to burn, effectively preventing the spread of fire.

For construction companies, using safety nets that have been tested and approved by GB 5725 equipment is an important manifestation of implementing safety production responsibilities. In recent years, many departments have explicitly required that safety nets used on construction sites must have a flame retardant performance testing report issued by a testing agency, and the issuance of this report is based on the testing data of GB5725 and GBT5455 standard equipment. Beijing Xinsheng Zhuorui Technology Co., Ltd. develops, produces and supplies GB5725 safety net flame retardant performance tester

Scope of application: GB5725 touch screen controlled safety net combustion performance (flame retardant) tester, also known as textile vertical combustion tester, is suitable for measuring the combustion (flame retardant) performance of various safety flat net vertical net dense mesh safety vertical net.

The GB5725 touch screen controlled safety net combustion performance (flame retardant) tester shall be tested according to the method specified in 6.1.6 of section 5.1.12 of GB5725 safety net for flame retardant performance and flame retardant flat (vertical) net. The duration of continuous combustion and smoldering should not exceed 4 seconds. According to the flame retardant performance of 5.2.2.9, the flame retardant performance of the dense mesh safety net shall be tested according to the testing method specified in 6.2.12. The continuous burning and smoldering time in the horizontal and central directions shall not exceed 4 seconds. The testing requirement is to randomly take five ropes with a length of 300 ± 5mm from the sample net, and test them according to the method specified in GB5455, with the results rounded to one decimal place.

At the same time, the application of equipment has also promoted the upgrading and replacement of safety net products in the construction industry. In order to pass strict flame retardant testing, production enterprises continuously optimize the formula of safety net materials, adopt technologies such as flame retardant fibers and coatings, improve the flame retardant performance of products, and promote the high-quality development of the entire industry. To a certain extent, it can be said that GB 5725 safety net flame retardant testing equipment is a "guardian" of fire safety in the field of construction.
