DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to an evaluation system and method for a word, and (d) is a system and method for evaluating adsorption performance of a gas molecule. _In the continuous gas adsorption performance [Prior Art] The purification tool has an adsorption property for a process such as chemical exhaust gas or separation of the rolling body mixture. There are many types of materials with gas absorption, such as porous materials (such as activated carbon: molecular two: stone), fabrics and filtration, materials (such as masks, filters). Therefore, it is necessary to select the most suitable materials for the adsorption and desorption properties exhibited by the materials under different adsorbed gas types and various environmental conditions. The method for determining the adsorption performance of an adsorbent material is large D3467 test standard. This test standard (4) allows gas (such as volatile organic solvents, water vapor, dust-containing gas) to flow through the sample to be tested with known == under the specified conditions, and determine the weight of the sample to be tested multiple times during the adsorption process. Once, until the sample weight no longer increases. In the traditional method, an empty column is first weighed to the weight. The sample to be tested is then filled in an empty column and its weight is measured to obtain a column weight. The column that has filled the sample to be tested is connected to the gas source to be adsorbed, so that the gas enters the column and flows through the sample to be tested for adsorption reaction. After every other period of time (eg every 5, 10, 15 or 3 minutes), block the gas and remove the column containing the sample to be tested. Wipe the column to remove moisture or other deposits on the surface and weigh it. The weight weighed is the weight of the sample to be tested, 1303715 plus the adsorbed gas molecules (the weight of the sample after adsorption). The weighted column is then connected to the gas source, and the gas is again passed through the sample to be tested. Repeat the removal of the column for weighing and installation until the sample weight is no longer changed after absorbing. The resulting data was converted to the adsorptivity of the sample to be tested using the following formula. L〇〇x (sample weight after adsorption - sample column weight) / (sample column weight - empty column weight) = percent adsorption However, conventional devices and methods have some disadvantages. One of them is that it is extremely inconvenient to remove the column containing the sample to be tested and to perform the weighing after the adsorption is carried out. The second is that the adsorption weight of the sample changes very little, and the environmental factors (such as temperature) after the column is removed from the device will cause great error in the data of the measurement. The third is that it is a waste of manpower for the experimental operator to monitor the entire process, and the operator may be exposed to harmful substances such as volatile organic gases or dust, which may affect health. The fourth is that the steps of the conventional method are troublesome, so it is impossible to obtain the adsorption data at multiple time points in a short time and cannot reflect the true adsorption property of the sample to be tested. The fifth is that the conventional apparatus and method are not easy to carry out the desorption reaction, and therefore are not suitable for evaluating the desorption performance of the sample to be tested. Therefore, there is a need for a simple and fast evaluation system and method. It can reduce the human error caused by the steps of the conventional method that requires the operator to repeatedly take out the adsorbent material to be tested and measure its heavy weight, and correctly evaluate the adsorption and desorption performance of the adsorbent. 6 1303715 SUMMARY OF THE INVENTION Accordingly, the present invention is directed to providing a simple, fast, and accurate gas adsorption evaluation system and method. The other direction of this month is to provide an evaluation system that continuously and instantly monitors the adsorption state of the suction material, which can obtain more effective information during the adsorption process, in order to reflect the true adsorption and desorption of the sample to be tested. performance. In view of the above, the present invention provides a continuous gas molecular adsorption system comprising at least one weight measuring device, a sample holder, a % environment generating device, a reaction chamber and a recording and computing device. The sample π is located in the reaction chamber and is used to place samples to be tested, such as porous materials (such as activated carbon, molecular sieves, zeolites), fabrics, transition materials (masks, filters, etc.). The weight measuring device is connected to the sample holder to detect the change in weight of the sample to be tested. The weight measuring device can be an electronic scale or any instrument that can be used to measure weight and transfer data to a recording and computing device. The environment generating device is connected to the reaction chamber to introduce the adsorption or desorption environment into the reaction chamber. The reaction chamber forms a reaction space around the sample holder for adsorption or desorption experiments. The recording and computing device is connected to the weight measuring device, and the data transmitted from the weight measuring device to the recording and computing device is recorded for data processing and analysis. In view of the above, the present invention provides a continuous gas adsorption evaluation method. In this method, a sample to be tested is placed on a sample holder, and a sample holder containing the sample to be tested is placed in a reaction chamber. The initial weight of the sample to be tested is detected by a weight measuring device. An environment-generating device is used to generate an adsorption environment, and the adsorption environment is introduced into the reaction chamber to cause the sample to be tested to undergo an adsorption reaction. The post-adsorption weight of the sample to be tested at any 7 1303715 intercalation point was measured during the adsorption reaction using a weight measuring device. The measured weight data is transmitted from the weight 1 measuring device to a recording and computing device. A software is executed by the recording and computing device to process the received data to produce an adsorption junction of the sample to be tested. The weight measuring device is used to detect the weight of the sample to be tested which has completed the adsorption reaction. A desorption environment is generated by the environment generating device, and the desorption environment is introduced into the reaction chamber to cause the sample to be tested to undergo desorption reaction. The desorption after the desorption of the sample to be tested at any time point is measured by the weight measuring device during the desorption process. During the desorption process, the weight data collected by the weight measuring device is transmitted to the recording and computing device. The received data is processed using a recording and computing device to produce a desorption result of the sample to be tested. Desorption results were established in the database for sample screening and comparison. The invention has the advantages that during the adsorption and desorption process, the weight is measured by using a weight measuring device which can continuously change the weight of the sample, and the operator needs to take the sample to be tested from the evaluation system and measure the weight. Human error caused by the action. Another advantage of the present invention is that the recording and computing device is used to control the system and record the results. The operator M does not need to monitor the test process throughout, so the manpower and time can be greatly reduced. Another advantage of the present invention is that the operator does not need to manually measure the weight of the sample to be tested, and can reduce the contamination and damage of the operator by chemicals. Still another advantage of the present invention is that a large amount of information can be acquired in a short time to display the true adsorptivity of various samples to be tested. Still another advantage of the present invention is that a plurality of analytes are constructed in a variety of environmental conditions and adsorption and desorption properties exhibited by the same adsorbed gas species. After entering the specified conditions, use this database to select 8 Ϊ 303715 = material adsorption performance comparison (4) to select the sample α port that meets the user's needs. Moreover, the present invention has an advantage in that it provides an evaluation method and system that can be applied to a wide range of fields, such as moisture absorption of materials, material drying speed, gas separation, chemical purification, and adsorption test of adsorbents.
