Description
Technical field
The present invention relates to the Surface Physical Chemistry technical field, specifically is a kind of microcomputer wetting angle measurement mechanism.
Background technology
In the Surface Physical Chemistry research process, wetting angle is a very important physical quantity.The measuring principle of solid powder wetting angle is according to the dynamic osmotic method of Washburn, when the wetting powder of wetting liquid and when the powder tubing string rises, the pipe internal pressure square with wetting time linear in the certain hour scope, look for the higher pressed powder of a pair of wetness degree one wetting liquid as reference, its wetting angle is made as 0, and the wetting angle of other system can calculate according to the pressure square slope meter with time relationship.Experimental implementation is that a certain amount of solid powder is packed in the glass tube of lower end with micro-pore septum sealing, and enrich to a certain fixedly scale, then glass tube is vertically placed, and allow the lower end stretch under the wetting liquid liquid level, solid powder is contacted with wetting liquid, the pressure of measuring in the glass tube with microbarograph changes, and reads one time force value at regular intervals at interval, then the square time is mapped with pressure.Force value was manually to read in the past, and it then is hand computation that mapping and wetting angle are calculated, and introduces personal error easily, and work efficiency is also low.
Summary of the invention
Force value when measuring the solid powder wetting angle in order to solve in the glass tube of filling powder is manually to read, and causes personal error and ineffective problem easily, and the utility model patent provides a kind of microcomputer wetting angle measurement mechanism.
The technical scheme of the utility model patent is: a kind of microcomputer wetting angle measurement mechanism is provided, and this device is assembled by computer, serial interface cable, microbarograph, sebific duct, glass tube, powder, wetting liquid, miillpore filter and glass cylinder.Wherein, described wetting liquid is contained in the glass cylinder, seals and inserts in the glass cylinder that wetting liquid is housed with miillpore filter after installing solid powder in the glass tube, and the glass tube other end connects sebific duct, sebific duct is connected with microbarograph, and microbarograph is connected with computer by serial interface cable.Behind the data input computer that microbarograph collects, go out wetting angle by computed in software.
The beneficial effect of the utility model patent is:
1, realizes the microbarograph data acquisition and control automatization, avoided manually reading and cause personal error, improved the accuracy of reading;
2, behind the data input computer that microbarograph is gathered, go out wetting angle, improved work efficiency by computed in software.
Description of drawings
Fig. 1 is the structural representation of microcomputer wetting angle measurement mechanism described in the utility model.
Fig. 2 is a software pressure acquisition runnable interface.
Fig. 3 is that the software wetting angle is calculated runnable interface.
Embodiment
Below by drawings and Examples the technical solution of the utility model is further described.
Contrast Fig. 1, microcomputer wetting angle measurement mechanism described in the utility model is assembled by computer 1, serial interface cable 2, microbarograph 3, sebific duct 4, glass tube 5, powder 6, glass cylinder 7, wetting liquid 8, miillpore filter 9, attemperator 10 and plug 11.Described wetting liquid 8 is contained in the glass cylinder 7, and glass tube 5 one ends are wrapped up with miillpore filter 9, and behind the powder 6 of packing into, the other end connects sebific duct 4, and sebific duct 4 is connected with microbarograph 3, and microbarograph 3 is connected with computer 1 by serial interface cable 2; Equal pressure stablize constant after, press " adopting zero " button on the microbarograph 3, after then one of " sample 1 " shown in Figure 2～" sample 5 " pressed in click, glass tube 5 is stretched under wetting liquid 8 liquid levels about 2mm, powder 68 of wetted liquid of beginning are wetting in the glass tube 5, wetting liquid rises along glass tube column, and the pressure in the pipe changes by microbarograph 3 detections, is gathered by computer 1 again; When pressure no longer changed, expression absorption was finished, and can enter next sample test.After all testing samples had all been surveyed, data were kept in the file by the test duration establishment, and filename is followed successively by Datal.txt～Data5.txt; Click " calculating wetting angle " shown in Figure 2 button and enter wetting angle calculating; If required physical data is not calculated in input, click " input σ, η " shown in Figure 3 button, physical data is kept at file Data.txt; Click " calculating wetting angle " shown in Figure 3 button and begin to calculate, result of calculation is kept at file Result.rtf.
