Abstract

The invention relates to a granule test device which comprises an air compressor, wherein the air compressor is connected with an air storage tank through an air pipe; the air storage tank is connected with an oil-water filter through an air pipe; the oil-water filter is connected with an air dryer through an air pipe; the air dryer is connected with a granule test machine through an air pipe; the granule test machine is connected with a dust collection bottle through an air pipe; the dust collection bottle is connected with a dust collector. The granule test device is simple in structure, low in cost, wide in dynamic measurement range, free from gear shift in the whole process, high in measurement speed, good in repeatability, convenient to operate and low in requirement on test conditions and operators.

Description

technical field [0001] The invention relates to a testing device, in particular to a particle testing device. Background technique [0002] According to the research of some industry experts in recent years, powder coatings have a critical particle size, larger than this particle size, the powder is not easy to agglomerate, otherwise it is easy to agglomerate. The particle size of the coating product should not be lower than the critical particle size, otherwise the storage properties of the product will become poor. Powder agglomeration seriously degrades performance. According to the sample data collected by some industry experts, when the particle size of the powder is smaller (in the case of the same distribution width), its fluidization factor also tends to decrease correspondingly, that is, the fluidity becomes worse. Poor fluidization will lead to unsatisfactory spray coating uniformity during spraying, which will affect the spraying effect, which is more obvious in...
