Abstract
The utility model discloses a heat extension testing arrangement for fire -retardant macromolecular material of inorganic hydroxide, including last anchor clamps, down anchor clamps, weight and scale, to go up anchor clamps and be equipped with the couple, lower anchor clamps are equipped with the weight seat, and the weight seat is equipped with removable weight, go up anchor clamps and anchor clamps down all including relative movable splint and the solid fixed splint who sets up, but the activity splint are equipped with the adjusting bolt of free rotation, solid fixed splint be equipped with with adjusting bolt assorted screw hole, the adjusting bolt screw in is fixed splint's threaded hole admittedly, through rotation adjusting bolt regulation activity splint and the gap length between the fixed splint admittedly, the solid fixed splint lower extreme at last anchor clamps is fixed to the scale. The utility model has the advantages of simple structure, dress materials conveniently, low cost, and the reading is convenient, accurate, the difference as a result that reading error arouses has been avoided.
Description
Technical field
The utility model relates to a kind of heat for inorganic hydroxide flame retarded polymeric material and extends proving installation.
Background technology
Hot elongation test is a kind of method of inspection of examination crosslinked polymer material plastic yield and permanent strain under heat and load effect, this test is under the test temperature more much higher than Applicable temperature and certain loading conditions, embodies plastic yield and permanent strain with the change of the extensibility of the heat ageing through the short period.Crosslinked magnesium hydroxide, aluminium hydroxide flame-retardant macromolecular material, need test the heat extensibility of material, can be used for weighing magnesium hydroxide, the crosslinking degree of aluminium hydroxide flame-retardant macromolecular material and heat resistance.
Heat extends proving installation and is generally divided into fixture, lower clamp, counterweight, rule.The markings of 20mm need be put on before test in the middle part of each large dumbbell shape sample, in the middle part of each little dumbbell shape sample, put on the markings of 10mm.Upper fixture clamps sample upper end, lower clamp adds sample lower end clamped by counterweight, hangs in baking oven.Have separated by a distance when current hot extension apparatus sample is placed and between rule, need sight line translation sense data during reading, possible reading has deviation.Each lattice of rule are 1mm, and for large dumbbell shape batten, reading differs lattice, result will be caused to differ 5%, and for little batten result just difference 10%, cause error larger.
Summary of the invention
Goal of the invention: the problem easily occurring deviation when the purpose of this utility model is and extends the sense data of proving installation existence for existing heat, provides a kind of convenient reading, extends proving installation for the heat of inorganic hydroxide flame retarded polymeric material accurately.
To achieve these goals, the utility model have employed following technical scheme: a kind of heat for inorganic hydroxide flame retarded polymeric material extends proving installation, comprise fixture, lower clamp, counterweight and rule, upper fixture is provided with hook, lower clamp is provided with counterweight seat, counterweight seat is provided with removable counterweight, described upper fixture and lower clamp include the ambulatory splint and strap that are oppositely arranged, ambulatory splint is provided with adjusting bolt free to rotate, strap is provided with the threaded hole matched with adjusting bolt, adjusting bolt screws in the threaded hole of strap, by rotating the gap length between adjusting bolt adjustment ambulatory splint and strap, described rule is fixed on the strap lower end of fixture.
Further, described hook is fixed on the strap upper end of fixture; Described counterweight seat is fixed on the strap lower end of lower clamp.
Beneficial effect: it is simple that the utility model has structure, dress is materialsed conveniently, and with low cost, convenient reading, accurately advantage, avoid the result difference that reading error causes.

Embodiment:
Below in conjunction with accompanying drawing the utility model done and further explain.
As shown in Figures 1 to 4, heat for inorganic hydroxide flame retarded polymeric material of the present utility model extends proving installation and comprises upper fixture, lower clamp, counterweight 3 and rule 1, upper fixture is provided with hook 2, and lower clamp is provided with counterweight seat 7, and counterweight seat 7 is provided with removable counterweight 3.Described upper fixture and lower clamp include the ambulatory splint 4 and strap 5 that are oppositely arranged, ambulatory splint 4 is provided with adjusting bolt 6 free to rotate, strap 5 is provided with the threaded hole matched with adjusting bolt 6, adjusting bolt 6 screws in the threaded hole of strap 5, regulates the gap length between ambulatory splint 4 and strap 5 by rotation adjusting bolt 6.Described rule 1 is fixed on strap 5 lower end of fixture, and described hook 2 is fixed on strap 5 upper end of fixture; Described counterweight seat 7 is fixed on strap 5 lower end of lower clamp.
As shown in Figure 5, upper fixture clamps sample 8 upper end, lower clamp adds sample 8 lower end clamped by counterweight 3, and rule 1 is adjacent with sample 8, so just so that direct reading, can solve the reading error that sight line translation brings.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
