管式爐毒性試驗設備

IEC 60754-1 / 2,NFX 70-100
管式爐毒性測試方法用於評估分解或燃燒過程中的有毒或腐蝕性產品。

該設備是小型靜態管式爐,其中將試樣(對於低密度材料通常為1克或0.1g)在坩堝中推入爐管中部並熱分解。爐溫為400、600和800°C的皮重用於表示在2升min-1的流動空氣中的氧化熱解,通風良好和通風不足的條件,在此溫度下它們可能會發生熱解和自燃。對於大多數溫度為400°C的材料,它們不會點燃,因此條件是氧化熱解。在600°C的溫度下,熱解速率可能會相當緩慢,從而使通風狀況良好;而在800°C時,由於熱解速率超過化學計量的空氣供應量,火災條件可能會接近通風不足率。廢水透過氣體檢測鼓泡器和氣袋驅動,以進行後續分析。

規格與功能
系統包括:
• 水平式爐具有以下尺寸:內徑65mm;總長625mm;加熱長度550mm;最高工作溫度為1200°C,配有溫度控制器和顯示螢幕。

Tube Furnace Toxicity

IEC 60754-1/2, NFX 70-100

The Tube Furnace Toxicity test method is used in the assessment of toxic or corrosive products during decomposition or combustion.

The apparatus is a small scale static tube furnace in which the test specimen (typically 1 gram or 0.1g for low density materials), is pushed, in a crucible, into the middle of the furnace tube and thermally decomposed.  Furnace temperatures of 400, 600 and 800°C tare used to represent oxidative pyrolysis, well-ventilated and under-ventilated conditions in flowing air at 2 litres min-1, where they may pyrolyse and auto-ignite.  For most materials at a temperature of 400°C they will not ignite, so the condition is oxidative pyrolysis.  At a temperature of 600°C, the rate of pyrolysis may be fairly slow, giving a well-ventilated fire condition, whereas at 800°C the fire condition may be closer to under-ventilated as the rate of pyrolysis exceeds the stoichiometric air supply rate. The effluent is driven through gas detection bubblers and gas bags for subsequent analysis.

Specification & Features
System comprises of:
•Horizontal tube furnace with the following dimensions: bore diameter 65mm; overall length 625mm; heated length 550mm; with operating temperature up to 1200°C, complete with temperature controller and display.
•Special quartz work tube of overall length 700mm complete with high temperature end collars
•100 porcelain combustion boats of appropriate dimensions to meet standard
•3 borosilicate glass wash bottles and, complete with 3 Drechsel wash bottle heads
•Associated tubing and fittings
•Loading tool for inserting combustion boat into furnace
•Magnetic stirrer
•Suction pump
•Calibrated flow meter

Options and Accessories:
•Thermocouple system to allow furnace temperature profile measurement with handheld temperature indicator
•Data Acquisition System to semi automate and record temperature profile, as well as auto start test, record test events with a remote handset.  Also records temperature profile during the test. The system can be configured to record the analogue signal voltage output of additional analysers (not supplied) for continuous measurements.  Raw test/temperature profile data is available for import into MS excel.  Windows 7 Notebook included
•Porcelain combustion boats (pack of 100)
•Borosilicate glass wash bottle (each)
•Drechsel wash bottle head (each)
•Spare tubing for above (10 metres)
