Embodiment 1

[0027] A rapid detection method for the combustion performance of a flame-retardant fiberboard, comprising the following main steps:

[0028] (1) According to the instructions of the oxygen index tester, cut the flame-retardant fiber board to be tested into 10-15 fiber strips with a length of 10cm*width of 10cm*the nominal thickness of the board;

[0029] (2) Turn on the power switch of the oxygen index tester, and warm up for 10 to 30 minutes;

[0030] (3) Zero adjustment: turn on the nitrogen, adjust the nitrogen pressure to 0.1MPa by adjusting the nitrogen pressure reducing valve knob on the oxygen index test instrument, and then adjust the nitrogen flow valve to stabilize the float flow rate of the glass rotameter at 10L / min, the oxygen percentage displayed on the display screen of the machine should be zero at this time, if it is not zero, then manually reset to zero through the adjustment button, after the zero adjustment is completed, turn off the main valve switch of ...

Abstract

The invention discloses a rapid detection method for combustion performance of a flame-retardant fiber board. The rapid detection method applies an oxygen index tester, adopts top end ignition and combustion time as an end point determination method and can simply judge flame retardant grade of the combustion performance of the flame-retardant fiber board, the method is simple in operation, short in consumed time, high in working efficiency and low in labor consumption, production effectiveness is greatly improved, product detection cost is saved, quantitative comparative analysis is facilitated, production effectiveness and product quality of flame-retardant fiber boards of an enterprise are obviously improved, and simplicity, easiness and good repeatability effects are realized on screening of a formula of a flame retardant and preliminary evaluation of combustion performance grade of a wood-based artificial board, so that the rapid detection method disclosed by the invention is a simple and easy rapid detection and judgment method with good repeatability.

Description

technical field [0001] The invention belongs to the technical field of flame-retardant wood-based panel detection, and in particular relates to a rapid detection method for the combustion performance of a flame-retardant fiberboard. Background technique [0002] At present, my country has become the world's largest producer and consumer of wood-based panels. However, wood-based panels are flammable materials, and there are some unsafe factors. With the strengthening of the implementation of the National Fire Protection Law, GB50016-2006 "Code for Building Design and Fire Protection" and the mandatory national standard GB 20286-2006 "Requirements and Marks for the Combustion Performance of Flame-retardant Products Used in Public Places" and the improvement of living standards and safety awareness , will greatly promote the healthy development of flame-retardant building materials and flame-retardant materials. The flame-retardant fiberboard with dual functions of flame-reta...
