Problems solved by technology

[0003] With the development of the economy and the rapid development of the construction industry, the requirements for building materials are getting higher and higher, because the requirements for the fire resistance of wood are getting higher and higher. However, the fire-retardant wood on the market is complicated and of good quality. Different, the flame retardant properties are uneven, so there is an urgent need for a test instrument that can measure the fire resistance of flame retardant wood

Embodiment 1

[0043] refer to figure 1 , a flame-retardant wood fire performance test furnace, which includes a test box 1, the opposite side walls of the test box 1 are provided with side-by-side doors 100, convenient for testers to install samples and ignite.

[0044] refer to figure 1 and figure 2 , the test chamber 1 is provided with a workbench 10, the workbench 10 is provided with a combustion chamber 2, the side wall of the combustion chamber 2 is provided with a combustion chamber 20 for the installation of fire-retardant wood, and the side wall of the combustion chamber 20 is provided with a The opening 21 that igniter stretches into, on the side wall of combustion chamber 20 and is positioned at the top of opening 21, observation window 22 is provided, and the side wall of combustion chamber 2 is provided with the gas pipe 23 that supplies gas input, and gas pipe 23 passes through opening 21 stretches in the combustion chamber 20, and the gas pipe 23 stretches into one end of t...

Embodiment 2

[0060] A test method using a flame-retardant wood fire performance test furnace, the specific steps are as follows:

[0061] S1, open the side-by-side door 100, first check whether the ventilation hole 24 is blocked, if it is blocked, close the first valve 204, open the second valve 206, start the blower 207, and the blower 207 blows the wind along the ventilation pipe 205 into the ventilation pipe 209 , and blow out from the vent hole 24 to reduce the possibility of ashes or debris blocking the vent hole 24, so that the gas can be easily input into the combustion chamber 20;

[0062] S2. Check whether the combustion chamber 20 and the installation groove 28 are clean. If there is residual ashes or debris, the vent pipe 209 is pulled out from the vent pipe 205, the connecting pipe 211 is separated from the vent pipe 205, and the positioning ring 212 is separated from the ring groove 210. Pull out the metal hose 213, then turn the ventilation pipe 209, and blow on the ashes or ...

Abstract

The invention discloses a flame-retardant wood fireproof performance test furnace and a test method thereof, and relates to the test furnace. The flame-retardant wood fireproof performance test furnace aims to solves the problem that in the prior art, a device for detecting a flame-retardant wood can be developed. The flame-retardant wood fireproof performance test furnace comprises a test box, wherein a working table is arranged in the test box, a combustor is arranged on the working table, a combustion chamber for mounting the flame-retardant wood is formed on the side wall of the combustor,an opening for allowing an igniter to extend therein is formed in the side wall of the combustion chamber, a gas pipe is arranged on the side wall of the combustor, the gas pipe penetrates through the opening to extend into the combustion chamber, a plurality of air vents are formed in the end, extending into the combustion chamber, of the gas pipe, a chimney is arranged on the top wall of the combustion chamber, a temperature sensor is arranged in the chimney, a sealing door is rotatably arranged on the side wall of the combustor, a sealing door and the opening are arranged oppositely, a smoke exhaust pipe is arranged on the top wall of the test box, a smoke conveying pipe is arranged between the chimney and the smoke exhaust pipe, a controller and a display are arranged outside the testbox, and the temperature sensor and the display are both electrically connected with the controller. Through the above arrangement, the fireproof performance of the flame-retardant wood can be quickly detected.

Description

technical field [0001] The invention relates to a test furnace, more specifically, it relates to a test furnace for the fire resistance performance of fire-retardant wood and a test method thereof. Background technique [0002] Wood is a lignified tissue formed by plants capable of secondary growth, such as trees and shrubs; when wood is burned, the surface layer is gradually carbonized to form a material with lower thermal conductivity than wood (about 1 / 3 to 1 / 2 of the thermal conductivity of wood) Carbonized layer; when the carbonized layer reaches a sufficient thickness and remains intact, it becomes a heat insulating layer, which can effectively limit the speed of heat transfer to the inside, so that the wood has good combustion resistance; taking advantage of this characteristic of wood, and then adopting appropriate Physical or chemical measures, to isolate it from combustion sources or oxygen, it is entirely possible to make wood non-combustible, flame-retardant or r...
