Abstract
A fast heating device for measuring thermally stimulated current comprises stainless steel pieces, a ceramic base, a copper gasket, mica washers, a spring, a screw rod and a butterfly nut, wherein the stainless steel pieces are fixed on the concave ceramic base by a screw, the lower end of the screw passes through the copper gasket and is connected with the concave ceramic base; the copper gasket, an upper stainless steel piece, mica gaskets, the mica washers, the spring, an lower stainless steel piece and a copper piece are installed on the concave ceramic base by the copper screw rod; the spring is arranged between an upper mica washer and a lower mica washer, a sample placing area is arranged between an upper mica gasket and a lower mica gasket, and a thermocouple can be added between the mica gasket and the upper stainless steel piece. The fast heating device for measuring the thermally stimulated current is reasonable in design, and simple in structure, can adopt controllable low pressure direct current heating so as to enable the temperature of a content sample to rise fast, and is easy to realize computer control by being combined with devices accessorily arranged, such as the thermocouple and the like.
Description
Technical field
The utility model relates to a kind of nonstorage calorifier that thermally stimulated current is measured that is used for.
Background technology
When thermally stimulated current is measured, need sometimes controllably to be rapidly heated (as 5 ℃/more than the s), and temperature higher (for example more than 500 ℃).Common TSC heater means has two kinds: a kind of is with the heating of temperature control electric furnace, and a kind of is the oil bath heating.The space of conventional heating is bigger, often is difficult to be rapidly heated, and energy consumption is also bigger, and is difficult for the consistance of the temperature of assurance sample temperature and heating plate.The thermally stimulated current instrument that part is high-grade be owing to will take into account temperature measurement, so high-temperature region performance (being higher than 300 ℃) is relatively poor relatively, and complex structure, makes, the operation and maintenance cost is higher relatively.
Summary of the invention
The purpose of this utility model provides a kind of nonstorage calorifier that thermally stimulated current is measured that is used for, and can well guarantee the consistance of sample temperature, and can be rapidly heated can be used for the measuring heating arrangement of thermally stimulated current.
The utility model is made up of stainless steel substrates, ceramic base, copper pad, mica washer, spring, screw rod, stainless steel substrates is fixed on the spill ceramic base by screw rod and hexagonal nut, hexagonal nut links by copper pad and spill ceramic base, wing nut, screw rod will be gone up copper pad, will go up stainless steel substrates, go up mica spacer, mica washer, spring, down mica spacer, down stainless steel substrates and down copper pad be installed on the spill ceramic base, spring is installed in the middle of the upper and lower mica washer.Between last mica spacer and following mica spacer is the sample rest area.Can add thermopair between last mica spacer and the last stainless steel substrates.
The utility model the utility model is reasonable in design, and is simple in structure, can adopt the heating of controlled low-voltage direct and the content sample is rapidly heated, and sets up device in conjunction with thermopair etc. and is easy to realize computer control.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model vertical view.
Embodiment
As shown in Figure 1, 2,1 on copper pad is strengthened supporting and electric action.Last stainless steel substrates 2, down stainless steel substrates 5 plays and supports and serve as the heating resistor effect.Last mica spacer 10 and following mica spacer 11 play support and heat-conduction electric insulation effect.Spring 4 and mica washer 3 play a supportive role.6 of ceramic bases are supported and supporting role.Thumb brass unt 12, copper screw rod 9, copper hexagonal nut play fixing and electric action.
During use, on twice copper sheets of ceramic base, add controlled low-voltage, can realize realizing being rapidly heated control in the space between last stainless and the following stainless steel substrates.
The last copper sheet 1 and copper screw rod 9, copper hexagonal nut 8, following copper sheet 7 and the copper wing nut 12 that support on the ceramic base 6 can play the effect of high-quality lead, serve as heating plate and go up stainless steel substrates 2 with following stainless steel substrates 5, between two stainless steel discs is exactly sample area, i.e. the temperature control zone.
Because but the last mica spacer 10 and the following mica spacer 11 of heat conduction, electrical isolation are arranged between last stainless steel substrates 2 and the following stainless steel substrates 5, and the middle size that has spring 4 to support scalable temperature control interval, so can guarantee that the temperature consistance is better between heating plate and the sample.
Because last rust steel disc 2 can well contact with testing sample by following mica spacer 11 by last mica spacer 10, following stainless steel substrates 5, the heating power of last stainless steel substrates 2 and following stainless steel substrates 5 can be by the Control of Voltage of two electrodes, just can reach higher power being not more than under 20 volts the controllable voltage, and sample controllably is rapidly heated.
