But one or more problems below the existence in various degree of above method: 1. suspension need leave standstill the long period, can know its suspension property; 2. can only observational measurement, during quantitative measurment, test error is larger; If 3. suspension without obvious layering or the layering used time longer time, and suspension has color to adhere to when making container opaque and cannot observe layering, then cannot test its suspension property; 4. the scope of application is little, and can not reflect the inner sedimentation situation caused because granularity is uneven of suspension; 5. test vessel is many, and operation steps is many, complicated operation; 6. sample again after leaving standstill a period of time, can suspension be stirred, cause error; 7. high to equipment precise requirements, device structure is complicated, as CN102435538A the proving installation mentioned; Deng.
Summary of the invention
The present invention is directed to the problem existing for above existing method, provide a kind of method of suspension suspension determinator and gravity model appoach test suspension suspension property.
Technical scheme of the present invention is as follows:
A kind of suspension suspension determinator, this device comprises an elongate tubular test container, fixture, force cell or electronic analytical balance, support; Described holder is in the upper end of test container, described support is by fixture support test container, make test container inclination certain angle θ, container bottom is placed in force cell test lead center or electronic analytical balance center, and test lead axis is perpendicular to surface level.
Preferred according to the present invention, the oblate container of described test container to be circular test tube or arbitrary cross section be identical ellipse.The test container of flat can reduce the change of center of gravity on container cross section direction and the error caused.
Preferred according to the present invention, described fixture also comprises pole, and support test container for support, during test, fixture pole and test container length direction central axis, strut support test container can freely rotate around pole perpendicular on the face of surface level.
Preferred according to the present invention, described test container and horizontal plane angle θ=10 ~ 85 °.

A method for gravity model appoach test suspension suspension property, comprise and use device of the present invention, step is as follows:
(1) clamp test container is used, fixture pole place straight line and test container length direction central axis;
(2) fixture pole is placed in support support end, fixture pole place straight line and plane-parallel, test container is tilted, container bottom is put in force cell test lead center, and fixture pole place is L perpendicular to the distance of the face of surface level and the intersection point distance container bottom of test container length direction center line; Force cell test lead axis is perpendicular to surface level, and be θ with protractor measurement test container length direction and horizontal plane angle, now force cell institute dynamometry is F 0, manual record or microcomputer record force cell institute dynamometry F automatically by information acquisition system 0;
(3) be that the suspension of M is poured in test container by the quality stirred, manual record or microcomputer are by information acquisition system automatic writing time and force cell institute dynamometry; Record different time t 1..., t ncorresponding torque sensor numerical value F 1..., F n, common tags is F; Artificial or microsystem curve plotting F-t;
(4) the distance l of suspension distance of centre of gravity container bottom is established, according to equalising torque and geometrical principle, known:
(F-F 0)Lcosθ=Mg(L-l)cosθ
l = - L Mg × F + ( 1 + F 0 Mg ) × L - - - ( I )
In formula: g---be acceleration of gravity.
According to L, θ, M, t that (1) ~ (3) record 1..., t n, F 1..., F n, obtain l according to above formula (I) 1..., l n, artificial or microsystem curve plotting l-t, can obtain suspension center of gravity curve over time, the subsidence curve namely during suspension cant angle theta angle.
When replacing force cell with electronic analytical balance, survey numerical value m with electronic balance and be multiplied by gravity acceleration g replacement force cell institute dynamometry F, i.e. F=mg, F 0=m 0g.
When different suspensions is settled down to identical F-t curve tangent line and time coordinate axle clamp angle, the corresponding time is shorter, and this suspension suspension is poorer.F-t curve is not by the impact of L and θ measuring error.
Suspension l-t curve tangent slope is suspension settling velocity.The settling velocity of different suspension identical settling time is larger, then suspension suspension property is poorer; Time corresponding when different suspension is settled down to identical l-t curve tangent line and time coordinate axle clamp angle is shorter, then the suspension property of this suspension is poorer.
Proving installation of the present invention and method are specially adapted to aqueous suspension, aqueous high molecular material suspension, aqueous inorganic material suspension etc., aqueous inorganic material suspension, as high temperature high-radiation energy-saving coating suspension, primarily of the high temperature high-radiation energy-saving coating suspension that the solid material such as monox or chromium oxide, zirconia, SiC, Brown Alundum, titanium dioxide, refractory clay, bentonitic clay and carboxymethyl cellulose, PA80 glue or the liquid such as water glass, water form.
Principle of the present invention: the suspension property of suspension is relevant with the motion conditions of suspension component gravitate, some component sedimentation of suspension under gravity, must cause suspension decentralization.In the identical time, suspension decentralization amount is larger, and namely sedimentation is more serious, shows that suspension suspension is poorer.The change that suspension center of gravity shifts the power caused easily is surveyed, then calculate the centre of gravity place of different settling time according to mechanics and geometrical principle, can obtain settling velocity and the subsidence curve of suspension, i.e. the suspension property of known suspension.
Advantage of the present invention:
(1) test data is accurate, and error is little, and it is good that identical suspension repeatedly tests consistance, can well distinguish different suspension;
(2) the settling velocity of quantitative test suspension, the i.e. suspension property of quantitatively characterizing suspension;
(3) can realize follow-on test, obtain suspension subsidence curve, the settling velocity change of reflection different time;
(4) can not be subject to suspension painted in vessel surface, the impact observing the situations such as layering difficulty, be suitable for suspension scope wide;
(5) methodological science, proving installation, operation and calculate simple, be suitable for manual measurement and machine is measured automatically.
