Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1.A kind of gel strength proving installation, comprising: the container 11 with hollow cavity 23, the accommodating gel 13 to be tested of energy in the hollow cavity 23 of described container 11, and described container 11 has the opening communicated with described hollow cavity 23; Have the reference test bar 15 of certain mass, described reference test bar 15 stretches in described hollow cavity 23 by described opening, described reference test bar 15 is provided with the first scale 21.
A kind of gel strength proving installation of present embodiment adds gel 13 to be tested in transparent vessel 11, reference test bar 15 is entered under the opening of container is in hollow cavity 23, the reference test bar 15 with a kind of quality under the effect of its power upwards, can sink in be tested gel 13 certain depth after reference test bar 15 stability under loading at self gravitation and gel.Utilize the first scale 21 that reference test bar 15 is arranged to obtain sinkage, according to the stressed relational expression of reference test bar 15, calculate the intensity of gel 13 to be tested.
After reference test bar 15 is stable, stressing conditions as shown in the formula:
GRS·A·H＝m·g (1)
Wherein: GRS is the intensity of unit length gel, MPa/m;
The cross-sectional area of A-reference test bar 15, namely reference test bar 15 with the contact area of gel 13 to be tested, mm
2;
The degree of depth of gel is sunk to, mm after H-reference test bar 15 stability under loading;
The quality of m-reference test bar 15, kg;
G-acceleration of gravity, N/kg.
Above formula is converted, obtains gel strength calculating formula:
During test, the quality m of reference test bar 15, cross-sectional area A and gravity acceleration g are all known quantities, after only needing bar 15 stability under loading to be measured, directly read through the first scale 21 degree of depth that reference test bar 15 sinks to gel, substituting into above formula can through simply calculating the gel strength of unit length.
The depth H of gel is sunk to after the key of the utility model test gel strength is accurately to obtain reference test bar 15 stability under loading.Therefore, present embodiment is provided with easy-to-read first scale 21 on reference test bar 15, and the utility model provides following two kinds of embodiments utilizing the first scale 21 to obtain sinkage H.
Refer to Fig. 1.Described container 11 is transparent, and described reference test bar 15 has the first end that can stretch in described hollow cavity 23 and the second end stretching out described hollow cavity 23, and described first scale 21, evenly increases to described second end for starting point with described first end.First scale 21 puts in hollow cavity 23 with reference test bar 15, the first end of reference test bar 15 contacts with gel 13 to be tested, time initial, reference test bar 15 sinkage is 0, because container 11 is transparent, directly can read through the first scale 21 depth H stretching into gel after reference test bar 15 stability under loading.
Refer to Fig. 2.Described reference test bar 15 has the first end that can stretch in described hollow cavity 23 and the second end stretching out described hollow cavity 23, and described first scale 21 is arranged between described first end and the second end, and described opening is in the numerical range of described first scale 21.Reference test bar 15 is put in after in hollow cavity 23, concordant described opening, read the first scale 21 initial time numerical value, as Fig. 2 (a); After bar 15 stability under loading to be measured, concordant described opening, reads the numerical value of the first scale 21 after reference test bar 15 stability under loading, and as Fig. 2 (b), numerical value when numerical value now deducts initial, is the actual depth H sinking to gel of reference test bar 15.
Further, please also refer to Fig. 1, Fig. 2 and Fig. 3.A kind of gel strength proving installation of present embodiment also comprises the righting plug 17 with through hole 16, described righting plug 17 can be located on the opening of described transparent vessel 11 by fixed cover, described reference test bar 15 can be actively located in described through hole 16, and the object arranging righting plug 17 mainly prevents reference test bar 15 from stretching into the rear run-off the straight of hollow cavity 23 of container 11.Once reference test bar 15 tilts, its power acting on gel will be no longer himself gravity, but partical gravity, thus cause final test structure bigger than normal.
In addition, in order to the adverse effect that the outside objective factor such as volume eliminated because of gel 13 to be tested is brought to test result, present embodiment is provided with the second scale 19 on the sidewall of container 11, described second scale 19 is used to indicate the volume of gel 13 to be tested, when the gel strength needing test comparison several groups different, identify several groups of gel volumes by the second scale 19, make its volume equal, according to the principle of control variable, eliminate the impact of other factors on test result as far as possible.
