二、產品概述:
將已知表面積的試件,放入溫度、濕度、空氣流速和空氣置換率控制在一定值的測試箱內。甲醛從試件中釋放出來,與箱內空氣混合,定期抽取箱內空氣,從箱中抽取空氣通過盛有水的洗氣瓶測定水中吸收的甲醛濃度。測試箱中空氣的甲醛濃度由洗氣瓶中的甲醛濃度和抽出的空氣體積計算,用毫克每立方米(mg/m3)表示。取樣是周期性的,直到測試箱內甲醛濃度達到平衡狀態(tài)。
Product Overview:
Put a test piece with a known surface area into a test box with controlled temperature, humidity, air velocity, and air replacement rate. The formaldehyde is released from the test sample, mixed with the air in the box, and the air in the box is periodically extracted. The air is extracted from the box and the concentration of formaldehyde absorbed in the water is measured through the air-wash bottle containing water. The formaldehyde concentration of the air in the test box is calculated from the formaldehyde concentration in the air wash bottle and the volume of the extracted air, and is expressed in milligrams per cubic meter (mg / m3). Sampling is periodic until the formaldehyde concentration in the test box reaches equilibrium.
