Description
Technical field
The present invention relates to polymeric material field more particularly to a kind of modified high molecular material thermal stability determination instrument.
Background technique
Natural polymer is to be present in animal, plant and the intracorporal polymer substance of biology, can be divided into natural fiber, natural
Resin, natural rubber, animal glue etc., synthesis high molecular material are primarily referred to as plastics, synthetic rubber and synthetic fibers three and synthesize greatly
Material, additionally includes adhesive, coating and various functional high molecule materials, and synthesis high molecular material has natural polymer
Sub- material is unexistent or more superior performance --- lesser density, higher mechanics, wearability, corrosion resistance, electricity are absolutely
Edge etc. is applied in high molecular material at a certain field, is needed to carry out performance measurement to high molecular material, is judged whether to answer
For this field, it is exactly to measure its thermal stability that it is most common, which to measure performance, for high molecular material, it is therefore desirable to dedicated thermostabilization
Property measurement device measurement.
Existing high molecular material measurement device is general, and such as application No. is 201511024978.2 authorization patents of invention
Described in " high molecular material thermal stability determination instrument ", it is mainly made of heater body, shake table and electric-control system, passes through
Electric control system controls heating and shake table shake, and solution mobility is in increase test tube to increase heating speed, but deposits in this scheme
It is also easy to produce resonance during test tube is in vibration, causes internal Polymer Solution easily to sputter and comes, influences measurement result, or even damage
Bad device, and vibration can accelerate the heat of test tube inner macromolecule solution to distribute speed, so that Polymer Solution is heated more slowly.
Summary of the invention
The purpose of the present invention is to solve vibration existing in the prior art solution resonance in test tube may be made to splash, damage
Bad experimental provision, influences experimental result, and shake that test tube can accelerate solution heat in test tube distributes speed, increases heating time
The shortcomings that, and the modified high molecular material thermal stability determination instrument proposed.
To achieve the goals above, present invention employs following technical solutions:
Modified high molecular material thermal stability determination instrument, including water bath box offer water-bath chamber, institute in the water bath box
It states and offers annular groove on water bath box, the annular groove annular is equidistantly fixedly installed with multiple telescopic rods, multiple described flexible
The upper end of bar is fixedly installed with test tube fixing dish, and spring, and the upper and lower ends of spring point are arranged on each telescopic rod
It is not fixed on the bottom surface of test tube fixing dish and the slot bottom of annular groove, the arbitrary region of test tube fixing dish can be by multiple flexible
It is moved up and down under the action of bar and multiple springs；
Multiple test tube holes are offered on the test tube fixing dish, sliding is inserted with test tube in each test tube hole, often
The nozzle of a test tube, which is filled in, is equipped with sealing-plug, tracheae is inserted on each sealing-plug, and tracheae is connected to test tube
The internal outside with test tube, sealing-plug can block the nozzle of test tube, avoid invisible spectro solution from splashing, and enable to try
When heated, internal solution heat dissipation reduces pipe, increases heating speed, reduces minute, the tracheae on sealing-plug can be avoided
Test tube is completely plugged by sealing-plug, prevents test tube from leading to tube breaking because internal pressure increases during heating, increases and survey
Surely the upper surface outside of the safety tested, the test tube fixing dish offers annular race；
The water-bath box cover is equipped with insulation cover, and the lower end of the insulation cover offers circular trough, the slot of the circular trough
Motor is embedded in bottom wall, the groove bottom wall that the output shaft of the motor passes through circular trough is fixedly installed with bull stick, the bull stick
One end is equipped with pinch roller, and pinch roller agrees with annular race, and the distance of pinch roller to annular race is greater than bull stick to test tube fixing dish
Distance, i.e. pinch roller is pressed on test tube fixing dish so that side compressed spring and telescopic rod that test tube fixing dish is pushed down by pinch roller,
Its test tube fixing dish is heeling condition, and when pinch roller rolls along annular race with the rotation of motor, pinch roller, which constantly changes, to be squeezed
The position for pressing test tube fixing dish, i.e., so that test tube fixing dish annular moves up and down, then the test tube energy that is plugged on test tube fixing dish
Enough to shake with test tube fixing dish in the intracavitary annular of water-bath, movement range is small, and shaking speed is uniform, so that invisible spectro solution is not
Situations such as splashing can be generated；
The other end of the bull stick is fixedly installed with counterweight box, and counterweight box enables to motor not send out during rotation
Life significantly shakes, and will not have an impact to the output shaft of motor in long-time use process, increases the use of device
Service life.
Preferably, the fixed peace in the lower end of the insulation cover turns have multiple electric mortiser needles, and multiple electric mortiser needle slidings are plugged in
