Paper permeability detector is a kind of specialized equipment for measuring paper permeability, and the permeability being mainly used in the special papers such as the cigarette paper in production of cigarettes, tipping paper, forming paper is measured.Because the air permeability of paper has considerable influence for cigarette tar content, so paper permeability detector is the important instrument equipment that tobacco business uses.
According to standard GB/T/T23227-2008 " cigarette paper, forming paper, tipping paper and there is the mensuration of material gas permeable degree of directed air permeable belt ", measure the pressure differential that pressure is defined as in measuring process between sample two faces.And the definition of paper permeability is under 1kPa measures pressure condition, pass through 1cm
2the air mass flow (cm on sample surface
3/ min).Therefore, measure the whether accurate air mass flow that can directly affect by sample surface of pressure, and then affect testing result, finally affect the quality of cigarette paper and cigarette.
The main model of air permeability detector of domestic current use has A20, TQY-III, TQY500, D23 etc., some instruments self are with measurement pressure detecting function, the interface that can be provided by instrument itself connects external pressure meter, realizes the monitoring and testing to measuring pressure.Major part instrument itself does not measure pressure-detecting device, and external pressure meter cannot be used to detect.The structure of the air permeability detector of domestic current use is incomplete same, but substantially all comprises source of the gas, pressure governor, measuring unit, the several part of gauge head assembly in its structure.Its measuring principle is all under certain pressure effect, and sample is held on suitable measuring position, measures the total air mass flow by sample surface.Malleation or negative pressure generation can be applied by the side of sample by the air-flow of sample.The common ground of air permeability detector is that the sample holder blow vent for clamping sample is rectangle, and the area defining this rectangle blow vent is in a standard 2.00cm
2± 0.02cm
2, its long limit is 2.000cm ± 0.005cm.
At present, the UP pick-up unit for paper permeability detector has no relevant research report.
Summary of the invention
Object of the present invention provides a kind of paper permeability detector pressure-detecting device being applicable to different vendor based on above-mentioned prior art situation just, this apparatus structure is simple, easy to use, be a kind of quick, accurate, direct special pressure testing tool, there is good versatility.
The object of the invention is to be achieved through the following technical solutions:
