Description
Technical field
The utility model relates to contact angle determination field, particularly a kind of water contact angle measuring instrument.
Background technology
Contact angle is at solid, liquid, gas three-phase intersection, is called contact angle from the angle of solid-liquid interface through liquid internal to gas-liquid interface.Contact angle is one of important parameter of material surface wetting property, and its measuring method has a lot, and what usually adopt at present is that sessile drop method is measured.The error produced when sessile drop method is measured mainly causes due to objective table injustice, is revolving the contact angle before and after turnback in addition owing to will measure same drop, higher to the performance requirement of measuring instrument main frame; And at present instrument is on the market all cost several ten thousand to the integral instrument of hundreds of thousands, its cost is high, takes up an area large, operates very complicated.
Summary of the invention
For the problems referred to above, it is lower, easy and simple to handle that the purpose of this utility model is to provide a kind of cost, and can meet the water contact angle measuring instrument of fundamental measurement requirement.
For solving the problem, the utility model provides a kind of water contact angle measuring instrument, comprises objective table, bracing frame, and the stationary shaft connected as one with objective table is vertically fixed on the backlight on objective table, and is fixed on the sleeve on bracing frame top; Form clearance fit between described stationary shaft and sleeve, described objective table, with stationary shaft translation or rotation, described sleeve is provided with at least one jackscrew; Described backlight be fixed with weight instrument and be marked with the standard lines perpendicular to objective table, when objective table is in horizontality, described weight instrument and standard lines overlap.
Further, the bottom of support frame as described above is provided with four footing adjusting screw.
Further, one end of described sleeve is provided with angle dial, and described stationary shaft surface is marked with index line along its length; When objective table is in horizontality, 0 ° of scale mark of described angle dial is mutually vertical with objective table, and described index line is just to 0 ° of scale mark position.
The beneficial effects of the utility model are: water contact angle tester of the present utility model, while meeting basic water contact angle measurement requirement, its cost is lower, take up an area space little, easy for operation, for economic base is more weak or the colony of experimental implementation limited space provides better help, be convenient to promote the use of.
Accompanying drawing explanation
Be described in further detail with regard to embodiment of the present utility model below in conjunction with accompanying drawing, wherein:
Fig. 1 is the utility model structural representation.
Embodiment
With reference to a kind of water contact angle measuring instrument shown in Fig. 1, comprise objective table 1, bracing frame 3, the stationary shaft 2 connected as one with objective table 1, be vertically fixed on the backlight 5 on objective table 1, and be fixed on the sleeve 4 on bracing frame 3 top; Stationary shaft 2 interts in sleeve 4, and and form clearance fit between sleeve 4, make objective table 1 can with the translation of stationary shaft 2, rotate translation or rotation, sleeve is also provided with a jackscrew 8, when stationary shaft 2 rotates or moves to assigned address, rotatable jackscrew 8 is fixed axle 2; Backlight 5 is fixed with weight instrument 7, and is marked with the standard lines 6 perpendicular to objective table 1, when objective table 1 is in horizontality, weight instrument 7 and standard lines 6 overlap.
Further, the corner, bottom of bracing frame 3 is provided with four footing adjusting screw 10, can in operating table surface not at ordinary times, adjusting bottom adjusting screw 10, ensures that objective table 1 is in level.
Further, one end of sleeve 4 is provided with angle dial 9, and stationary shaft 2 surface is marked with index line (not shown in FIG.) along its length; When objective table 1 is in horizontality, 0 ° of scale mark of described angle dial 9 is mutually vertical with objective table 1, and index line is now also just to 0 ° of scale mark position.
Operation steps of the present utility model is as follows:
1, bracing frame is placed in experiment plane, unclamp jackscrew, stationary shaft is rotated and causes index line alignment angle index dial 0 ° of scale mark position compression jackscrew, observe weight instrument whether to overlap with the standard lines being strictly perpendicular to objective table, if do not overlapped, regulate base angle screw, until both overlap, now known objective table is adjusted to level;
2, an external camera, and regulate the distance between camera and objective table to make object on objective table can blur-free imaging, and the deionized water of 5 microlitres is dropped in stage surface; If imaging is clear not, also can unclamps jackscrew translation stationary shaft gently, compress again after making imaging clearly.
3, after drop contact angle upward being observed, when needing to obtain drop contact angle down, unclamp jackscrew and stationary shaft is rotated 180 °, data are read by angle dial, and observe weight instrument whether to overlap with standard lines, if do not overlapped, slowly rotate stationary shaft fine setting or again adjusting bottom adjusting screw adjust, then compress jackscrew start observation.
The above; be only the better embodiment of the utility model; but the utility model protection domain is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore the utility model protection domain is as the criterion with the protection domain of claims.
