As an important part of building safety, the test of fireproof performance of fireproof doors is crucial. During the production process, fire door factories pass a series of strict tests to ensure that the fireproof performance of the products meets the standard requirements. In this paper, we will introduce how the fireproof door factory tests the fireproof performance, and elaborate from four subheadings.
Initial Condition Setting and Sample Preparation
Before the fire performance test, the fireproof door factory first sets the initial conditions, including the temperature and humidity of the testing environment and other parameters to ensure the accuracy of the test results. At the same time, according to the test requirements, select representative fireproof door samples for preparation. The samples should have the same material, structure and process as the products in actual production to ensure the reliability of the test results.
Combustion Test and Fire Resistance Time Determination
Combustion test is the core part of fireproof door performance test. In the test, the fireproof door samples are placed in specific combustion equipment to simulate the fire scene. The testers evaluate the fireproof performance of the fireproof door by observing the burning situation of the sample, the flame spreading speed and the smoke and toxic gas produced during the burning process. At the same time, by recording the time from the start of fire to the loss of fire protection function of the sample, that is, the fire resistance time, to determine whether the fireproof door meets the standard requirements.
Thermal Insulation Performance Test
In addition to the combustion test, the fireproof door factory also conducts the heat insulation performance test. In the test, the fireproof door samples are placed in a high temperature environment to test their thermal insulation performance. Testers evaluate the thermal insulation effect of fireproof doors in fire by measuring the surface temperature of the samples at different points in time. This test helps to ensure that fireproof doors can effectively insulate heat and protect people in a fire.
Analysis and Improvement of Test Results
After completing the test, the fireproof door factory analyzes the test results comprehensively. For the samples that do not meet the standards, the factory will analyze the reasons in depth and make improvements for the problems. Through optimizing the selection of materials, improving the production process and strengthening the quality control and other measures, the fireproof performance of the fireproof door will be enhanced. At the same time, the fireproof door factory will also compare the test results with similar products in order to assess the advantages and shortcomings of its own products and provide reference for future R&D and production.
In short, fireproof door factory ensures that the fire resistance of fireproof doors meets the standard requirements through a series of steps such as setting initial conditions, conducting combustion tests and thermal insulation tests, and analyzing and improving test results. These strict testing processes not only help to improve the quality of fireproof doors, but also provide a strong guarantee for safeguarding people's lives and properties.
