The utility model has the advantages of wide test range and favorable accuracy and data repeatability.
Description
The utility model belongs to the device with mechanical stress test solid material strength characteristics.
The test of macromolecular material swelling behavior is to adopt to be interrupted the swelling sample of weighing at first, or in a graduated tube, read the method that cumulative volume increases, this class methods complex operation, error are big, more can not note the adding solvent swelling behavior of moment at any time, can not be used for detecting the size of macromolecular material swelling stress.Document ［ 1 ］ has been introduced a kind of working sample that is used at the device of solvent swelling state with the birefringent variation of the generation that stretches, and is one of assembly in the photoelastic experiment device.K.L.Wun adds in said apparatus with altimeter test sample product change in size and surveys solvent swelling state sample balance modulus in compression
(2), but this also is one of assembly in a whole set of experimental provision.Shanghai nonmetal testing machine factory produces a kind of SC-40 type compression stress relaxation instrument that is used to measure rubbery sample compression deformation STRESS VARIATION.Above-mentioned existing device all can only be used for measuring a kind of data of single performance, can not temperature control, thereby can not study performance to dependence on temperature.SC-40 type compression stress relaxation instrument is not to measure under the condition of the constant deformation of strict guarantee, and design concept is improper.In addition, do not see as yet about carrying out the swelling dynamics of macromolecular material and the report of swelling sample stress relaxation behavior measure with similar device yet.
The purpose of this utility model provide a kind of multi-functional, can control temperature, and can be later on continuous digital data recording system in succession, be used for testing the device of various macromolecular material swelling behaviors separately.
The purpose of this utility model is achieved in that this swelling behavior analyzer mainly wraps and knows tension and compression strain gauge (measurement range is at 1～2 kilogram), dial gauge, constrictor and constrictor head, the compression sample groove of being furnished with constant temperature jacket, magnet base, worktable, adjusting fine thread leading screw and 8 parts of pilot lamp.Its principle of operation is as follows: the portion that sample is placed spill sample cell ［ 16 ］, and the power supply of connection sensor ［ 11 ］, rotating adjusting fine thread screw mandrel ［ 1 ］ moves down sensor ［ 11 ］, the constrictor ［ 7 ］ and the constrictor head ［ 8 ］ that are connected on the dial gauge bottom simultaneously press down, pilot lamp ［ 15 ］ circuit when sample in the groove contacts is connected and is lighted when ［ 8 ］, when continuing to press down again, the force of compression of sample is exported to the independently register system that is connected with this analyzer by ［ 11 ］, write down stress value, meanwhile on dial gauge ［ 6 ］, read strain value synchronously.When pilot lamp ［ 15 ］ is bright, inject sweller, constantly the variation of track record swelling stress also can keep a constant strain value, notes stress relaxation in time.
［ 16 ］ be made of transparent material, be convenient to observe, spill is particularly conducive to the placement and the compression of sample, have above band for liquid or gas pass in and out the lid of two apertures of usefulness respectively.［ 16 ］ dispose a constant temperature jacket ［ 17 ］ outside, with the recirculated water temperature control.Worktable ［ 10 ］ is (the passing through screw rod) of adjustment height, after sample test finishes, can reduce height of table fast, takes off sample cell.Control the very fine tuning and steady of lifting of ［ 11 ］ with regulating fine thread leading screw ［ 1 ］.［ 6 ］ be connected with magnet base ［ 19 ］ with magnetic force dial gauge support ［ 18 ］ by dial gauge sliding bar shell ［ 5 ］, can guarantee that ［ 6 ］ are motionless in test process.
The advantage that the utility model compared with prior art has is that function is many: but both equilibrium swelling modulus of working sample, and the swelling dynamic process of track record dry sample at any time again can also constantly be followed the tracks of and do or the stress relaxation process of swelling sample; Applied range: sample can be a dry sample, also can be the swelling sample, allows the rigidity of sample to change within a bigger scope, and test performance is good: sensitivity and degree of accuracy height, accuracy and data good reproducibility (for details see attached table 1 and accompanying drawing 5)
