Embodiment Construction

[0037] see image 3 and Figure 4 , the new bag method automatic adopting system shown in the figure includes a sampling bin 100. The sampling bin 100 is provided with a constant temperature and humidity unit, an inlet fan, and a filter, and an air outlet and an outlet are provided on the wall of the bin body. The air outlet, the outlet of the fan inlet is connected with the outlet of the filter, and the outlet of the filter 4 is connected with the air outlet (not shown in the above figure, see figure 1 ); heating components in the sampling chamber 100 (not shown in the figure). The heating part is controlled by the PLC controller to realize automatic heating. After the temperature reaches the target value, it will automatically keep warm, without the need for personnel to monitor the operation, saving personnel from waiting for a long time.

[0038] The new bag method automatic adopting system includes compressed air solenoid valve 200, vacuum pump 300, vacuum valve 400, ni...

Abstract

A new type of bag method automatic adopting system disclosed by the present invention includes: a sampling bin, and also includes: a heating component arranged in the sampling bin; a compressed air solenoid valve; a vacuum pump, a vacuum valve, and a nitrogen gas source , at least one charging and exhausting device, at least one sampling device and PLC controller. The bag method automatic adopting system of the present invention can cope with the evaluation and comparison of VOC data of different interior products, ensure the accuracy and validity of the data, avoid the deviation caused by manual operation, and improve the efficiency of bag method automatic sampling.

Description

technical field [0001] The invention relates to a system for automatically adopting the bag method, a test method for volatile organic compounds in parts. Background technique [0002] The structure of the sampling chamber currently used in the bag method is as follows: figure 1 As shown, it includes a bin body 1, in which a constant temperature and humidity unit 2, an air intake fan 3, and a filter 4 are arranged in the sampling bin 1, and an air exhaust port 5 and an air outlet port 6 are provided on the top of the bin body 1, and the air inlet The outlet of fan 3 is connected with the outlet of filter 4 , and the outlet of filter 4 is connected with air outlet 6 . Sampling systems used such as figure 2 As shown, the adopting system includes a sample bag 10 and a blank bag 20 arranged in the sampling chamber, and two valves 11, 12, 21, 22 are respectively arranged on the sample bag 10 and the blank bag 20, and the valve 11 on the sample bag 10 passes through The Teflon...
