主要用途：
Main uses:
適用于確定一種材料是否具有難燃性。試驗裝置包括燃燒豎爐和控制儀器等。
Applicable to determine whether a material is hard to burn. The test device comprises a combustion furnace and control instrument.
建筑材料難燃性試驗機(jī)
Difficult flammability for building materials testing machine
符合GB/T8625、DIN4102《建筑材料難燃性試驗方法》，在規(guī)定的條件下判定建筑材料是否具有難燃性，凡是經(jīng)過燃燒豎爐試驗合格并能通過建筑材料可燃性試驗的材料均可定為難燃性建筑材料。
According to GB/T8625, DIN4102 "building materials difficult flammability test method", to determine whether the building material is hard to burn under stipulated conditions, usually through the combustion furnace test and by building materials flammability test materials can be difficult flammability for building materials.
本方法的試驗裝置主要包括燃燒豎爐及控制儀表兩部分
The test device of the method mainly comprises a combustion furnace and control instruments part two
一、試驗裝置:
A, test device:
1、燃燒豎爐：燃燒豎爐主要由燃燒室、燃燒器、試件支架、空氣穩(wěn)流器及煙道等部分組成。其外形尺寸為1 020mm×1 020mm×3 930mm。
1, the combustion furnace: combustion furnace is composed of a combustion chamber, a burner, specimen bracket, air regulator and flue components. Its size is 1 020mm × 1 020mm × 3 930mm.
2、燃燒室：燃燒室由爐壁和爐門構(gòu)成，其內(nèi)空尺寸為800mm×800mm×2 000mm。爐壁為保溫夾層結(jié)構(gòu)，爐門分為上、下兩門，分別用鉸鏈與爐體連接，其結(jié)構(gòu)與爐壁相似。兩門借助手輪和固定螺桿與爐體閉合。在上爐門和燃燒室后壁設(shè)有觀察窗。
2, the combustion chamber: the chamber formed by the furnace wall and the furnace door, the inner space size is 800mm × 800mm × 2 000mm. Furnace wall heat preservation sandwich structure, the door is divided into the upper, two doors, and the furnace body is connected by hinges, and the structure of the furnace wall similar. Two door by hand wheel and the fixed screw and the furnace body is closed. In the door and the combustion chamber wall is provided with an observation window.
3、燃燒器：燃燒器水平置于燃燒室中心，距爐底1 000mm處。
3: burner, burner level in the center of the combustion chamber, from the bottom 1 000mm.
4、試件支架：試件支架為高1 000mm的長方體框架，框架四個側(cè)面設(shè)有調(diào)節(jié)試件安裝距離的螺桿，框架由角鋼制成.
4, the specimen holder: specimen bracket is a cuboid frame height of 1 000mm, four side frames is provided with a regulating specimen installation distance of the screw, the frame is made of angle steel
5、空氣穩(wěn)流器：空氣穩(wěn)流器為一角鋼制成的方框，設(shè)置于燃燒器下方。方框底部鋪設(shè)鐵絲網(wǎng)，其上鋪設(shè)玻璃纖維氈。
5, air regulator: air regulator for angle steel box, is arranged on the burner. The box at the bottom of the laying of barbed wire, which laying glass fiber mat.
6、煙道：燃燒豎爐的煙道為方形的通道，其截面積為500mm×500mm，并位于爐子頂部，下部與燃燒室相通，上部與外部煙囪相接。
6: the burning furnace flue, flue is square channel, the cross section of 500mm * 500mm, and is located in the top of the furnace, the lower part is communicated with the combustion chamber, the upper and external chimney.
二、控制儀表：
Two, control instrument:
燃燒豎爐的控制儀表包括流量計、熱電偶、溫度記錄儀及溫度顯示儀表等。
The combustion furnace control instruments including meter, thermocouple, temperature recorder and temperature display instrument.
1、流量計：甲烷氣和壓縮空氣所用流量計，甲烷為6~60L/MIN可調(diào)，空氣為3~30L/MIN可調(diào)。
1, the flowmeter flowmeter: methane gas and compressed air, methane is 6~60L/MIN adjustable, adjustable air 3~30L/MIN.
2、熱電偶：煙道氣溫度和爐壁溫度的測定均采用精度為Ⅱ級，外徑不大于3mm的鎳鉻—鎳硅鎧裝熱電偶。
2, the thermocouple: Determination of flue gas temperature and wall temperature of the gasifier are used in precision for grade II, outside diameter less than 3mm nickel chromium - nickel silicon thermocouple.
