Abstract
The utility model is a short cut glass fiber grain fineness distribution detecting instrument, comprising a group of screen clothes (1) and vibrating motors (3) which are arranged on a vibrating platform (2), a transducer (4) and a time relay (5). If the utility model is adotped, the grain fineness distribution situation of the short cut glass fiber can be detected quickly and more accurately; thus the utility model is the short cut glass fiber grain fineness distribution detecting instrument which has simple operation and easy use.
Description
One, technical field
The utility model relates to a kind of short glass fiber size-grade distribution detector.
Two, background technology
Short glass fiber is one of important reinforcing material of polymer matrix composites.In all types of plastic, as PA, PP, PBT, PET, PC or the like, add glass fibre, can significantly improve the predictability of dimensional stability, intensity, toughness, thermotolerance and environmental resistance, recycling performance and these performances of compound substance.
Chopped glass fiber dimension at first will add special-purpose extruder by hopper, carries out continuous thermosol jointly with plastic substrate, extrudes, cold cut, cut-out granulating.Glass fibre whether can be in this process by fully, to be evenly dispersed in the resin matrix be very crucial, this will directly determine performance of composites.If wish to obtain the plastics material grain of homogeneous, must guarantee that at first short glass fiber adds the speed uniformity of special-purpose extruder by hopper, that is to say that the additional proportion that must at first guarantee short glass fiber and plastics material grain is reliable and stable.This just requires short glass fiber flowability when adding extruder very good, and will meet this requirement, and just necessarily requires little, the uniform particles of short glass fiber lousiness amount.
Generally speaking, the granularity that detects material can adopt ways such as sieve, sedimentation, range estimation, and the most frequently used way is the test screen over-size.According to data, adopt the way of rotating to measure the granularity of short glass fiber abroad usually, and this method can only be tested a numerical value at every turn by the cylinder timing that has certain pore size, fixed frequency.
Three, summary of the invention
The purpose of this utility model provides a kind of in short glass fiber is produced, can more accurately, simply, promptly detect the granule size of glass fibre and uniformity coefficient, and the short glass fiber size-grade distribution detector simple to operate, easy to use of grain-size distribution curve figure that can disposable description detected object.
The technical scheme that the utility model is taked is: it is made up of one group of screen cloth and vibrating motor, frequency converter, the time relay that has regular mesh that is placed on the shaking platform.Screen cloth is placed on the shaking platform in a certain order, under the shaking platform vibrating motor is housed, and relay connects with vibrating motor by frequency converter.
Adopt the utility model, can more accurately, simply, promptly detect the size-grade distribution situation of short glass fiber, grain-size distribution curve figure that both can disposable description detected object.Have characteristics such as simple in structure, easy to use.
Three, description of drawings
Accompanying drawing is the utility model synoptic diagram.
Four, specific implementation method
The utility model as shown in drawings, one group of garden shape screen cloth 1 that has a uniform mesh is arranged in order from 6.0mm～1.5mm and is placed on the shaking platform 2 in the aperture in a certain order, by the shaking frequently of frequency converter 4, the time relay 5 control vibrating motors 3, time of vibration.The glass fibre that requires to detect is placed on, from top to bottom one group of screen cloth 1 descending by the aperture, regulates the setting of frequency converter 4, the time relay 5.After vibration finished, by weighing, the screen cloth that calculates different apertures tailed over detection, can obtain a series of continuous data and curve plotting figure, judged short glass fiber size-grade distribution situation thus.
Claims (1)
- A kind of short glass fiber size-grade distribution detector, it is characterized in that: it is made up of one group of vibrating motor (3), frequency converter (4), the relay (5) that has the garden shape screen cloth (1) of regular mesh and be located under the shaking platform (2) that is placed on the shaking platform (2), the descending uniform arrangement in aperture of screen cloth (1) side, relay (5) connects with vibrating motor (3) by frequency converter (4).
