Embodiment 1

[0032] A closed storage slow-release micro-atmosphere collection method, which is used to collect a certain industrial epoxy resin closed-storage slow-release micro-atmosphere collection with a storage duration of 6 months. The steps are as follows,

[0033] Step 1: Obtain the mass of the epoxy resin, obtain the volume of the storage environment space of the epoxy resin, and obtain the volume-to-mass ratio of the material to be stored according to formula [I]; the volume-to-mass ratio refers to the ratio of volume to mass;

[0034] Capacity ratio = m 1 / V 1 ………………………………[I]

[0035] In the formula, V 1 Indicates the volume of the storage environment space where the material needs to be stored, m 1 Indicates the quality of the material to be stored;

[0036] After calculation, the volume of the storage environment space where the epoxy resin is located is 1.5 cubic meters (1500 liters), the mass of the epoxy resin to be stored is 20 kilograms (20000 grams), and the volume-to...

Abstract

The invention provides a method for collecting a closed-storage slow-release micro-atmosphere. The steps include: obtaining the capacity-to-mass ratio of the material to be stored; making a closed-storage, slow-release micro-atmosphere collecting device; The quality of the storage material that should be placed, weigh the sample to be tested and put it into the collection device, package the collection device and put it into the test environment to start the natural storage test or accelerated storage test; after the storage test is carried out for a certain period, use a sampler to extract The micro-atmosphere inside the acquisition device was analyzed. By simulating the capacity-to-mass ratio under actual storage conditions and adopting a collection device with a specific structure as the micro-atmosphere enrichment container, the invention can make the collection stability of the micro-atmosphere good, the parallelism of the test is greatly improved, and the accuracy of the test result is greatly improved. ; It has been proved by experiments that the deviation of the micro-atmosphere collected after the storage test by the method of the present invention is less than 10%.

Description

technical field [0001] The invention relates to a closed storage slow-release micro-atmosphere collection method. Background technique [0002] The phenomenon of material storage aging occurs from time to time, especially the polymer material may degrade and release the atmosphere during the storage process. The collection of the atmosphere is of great significance for the monitoring of the aging of the polymer material that requires long-term inventory. How to carry out reasonable and consistent storage Atmospheric collection under conditions is a realistic technical problem currently facing. [0003] At present, there are mainly two types of micro-atmosphere collection methods for material storage and slow-release. One is to use the sample body stored for a certain period of time to directly extract the volatilized micro-atmosphere. The former requires that the sample body has enough space to stay in an atmosphere with a concentration above the detection line, while the l...
