Method for manufacturing performance test sample of sealant for plugging filter bag pinhole

Abstract

The invention discloses a method for manufacturing a performance test sample of a sealant for plugging a filter bag pinhole. The method comprises the following steps: firstly, cutting two identical filter materials, namely, a filter material A and a filter material B, from a raw material for manufacturing a filter bag, wherein one filter material is equipped with a gluing area and the other filtermaterial is equipped with a bonding area; overlapping and aligning the gluing area and the bonding area of the two filter materials and fixing on a manufacturing device; uniformly coating the gluingarea with the sealant by using a brush coating mechanism, flattening and then bonding the bonding area on the gluing area coated with the sealant, thereby forming a bonding part; using a pressing mechanism for applying an adjustable pressure to the bonding part till solidifying the sealant on the bonding part, thereby obtaining a test sample. According to the method, the raw material of the test sample is cut off from the raw material for manufacturing the filter bag and the manual operation during the process of manufacturing the test sample is reduced, so that the method disclosed by the invention has the advantages of high specificity, objectivity and accuracy.

Description

technical field [0001] The invention relates to the technical field of making sealant performance testing samples, in particular to a method for making a sealant performance testing sample for pinhole plugging of filter bags. Background technique [0002] As the heart of the dust collector, the filter bag has a great influence on the smoke and dust emission of the dust collector. With the increasingly stringent national environmental protection requirements, the bag dust removal industry is also facing more severe challenges. Penetration, resulting in the risk of dust collector emissions exceeding the standard, and the filter bag pinhole coating sealant helps to avoid the risk of dust penetrating through the pinholes, and further ensures that the dust discharge meets the standard. However, the performance of the sealant used to block the pinholes of the filter bag is uneven, and the sealing effect on the pinhole of the filter bag is also uneven. For the evaluation of the per...

Problems solved by technology

[0003] However, the existing methods for making test samples usually carry out heat-resistant and acid-alkali-resistant treatments on the sealant, and the test samples are obtained after the treatment. The performance of the sealant is judged by the difference in its appearance. First of all, the sealant is not directly applied to the filter material of the filter bag in this production method, and the performance of the sealant is only judged by analyzing the change of the sealant itself. The advantages and disadvantages of the test sample are not targeted; secondly, the test sample produced by this production method has many artificial operations in the process of making the test sample, which makes the test sample produced have the disadvantages of strong subjectivity and inaccuracy

[0004] In view of this, the present inventor aimed at the many defects and inconveniences caused by the imperfect method of making the above-mentioned sealant performance test sample for pinhole plugging of the filter bag, and deeply conceived, and actively researched and improved the trial production and developed and designed this invention
