The thermal deformation, vicat softening point temperature tester products detail says:
 
 
 
 
Thermal deformation and vicat softening point temperature tester is mainly used for polymer materials (such as plastic, rubber, nylon, electrical insulating materials, etc.) of the thermal deformation temperature and vicat softening point measurement.Apply to the universities and colleges, scientific research units and the product quality supervision, inspection unit.The machine USES a Windows 98, Windows 98 or Windows xp Chinese operation interface, control software, in the process of test, monitoring the real experiment temperature, the deformation curve, and dynamically when real draw the curve of the temperature, deformation, realize the historical inventory, print test reports, so that future query at any time before the test data, for a variety of experimental data contrast research, is a highly intelligent test instrument, when using the mouse to click anywhere in the deformation, temperature curve, interface of the deformation and the temperature will automatically display here.
Thermal deformation and vicat softening point temperature tester for vertical tank structure, automatic constant temperature medium USES 45 DHS in the double helix mixing system, tank with special structure, temperature uniformity, good accuracy maintain plus or minus 0.5 ℃.And adopt advanced SCR control temperature, displacement sensor with a fine adjustment and fine-tuning double adjustment method, has the urgent stop switch, the control panel to the locked door type structure, machine repair, maintenance is convenient, lifting system model for an organic whole, reduce noise.Therefore, medium temperature gradient is small, uniform temperature, when the temperature of the test is to limit temperature automatically stop heating, test machine has the function of automatic lifting, simple operation, excellent price performance ratio in the similar type.
The thermal deformation and vicat softening point temperature tester conform to standard:
(GB/T 1633-1633 idt ISO 306:306) determination of the vicat softening temperature (VST)
GB/T 1634.1 2004 (idt ISO75 - "03) plastic load deformation temperature measurement (general test method)
GB/T 1634.2 2004 plastic load deformation temperature measurement (plastic, hard rubber and long fiber reinforced composite material)
GB/T 1634.3 2004 plastic load deformation temperature measurement (high intensity thermosetting laminated material)
GB/T 8802-8802 (eqv ISO 2507:1995) thermoplastic pipes, pipe fittings vicat softening temperature measurement
The thermal deformation, vicat softening point temperature tester concept:
D card (VST) set: put the sample in liquid medium or heating box, under the condition of constant temperature measurement standard pressure needle in (50 + 1) N force, under the action of pressure into the cut out from the pipe or fitting the temperature at which the sample within 1 mm.
Thermal deformation (HDT) definition: a standard sample to flat (preferred) or three point bending under constant load side way, make its produce GB/T 1634 related part of one of the bending stress, under the condition of uniform temperature, measured with bending strain increment corresponding to the standards set by the temperature at which the deflection.
Side: "flat" and "side", and clearly pointed out that the optimum way of flat, is only optional side way, and will be revoked.
Span: bearing and distance between two contact wire sample, from a (100 mm) to (flat) two 64 mm and 64 mm (side), and specifies tolerance requirement that span the L should be (100 + 1) mm, span length L (64 + 1) mm.
Three ways in which the load deformation temperature
A method: 1.80 Mpa bending stress
B: 0.45 MPa bending stress
C: 8.00 MPa bending stress
