When using device of the present invention; At first answer the established standards rate of heat addition; The 27cm3 dibutyl phthalate packed into be furnished with in the steel pipe of 1.5mm orifice plate, the recording liquid temperature rises to 285 ℃ of used times and calculates the rate of heat addition from 135 ℃, regulates the propane flow with gas meter; Until the rate of heat addition is 3.3K/s ± 0.3K/s, makes an experiment according to the following step then:
Solid sample:
Phase one is with 9cm
3Sample is packed in the taring steel pipe, with the power that is applied to steel pipe entire cross section 80N with the material compacting, if material is compressible; Then add material and compacting, till being filled to, confirm used sample gross mass apart from mouth of pipe 55mm; In the taring steel pipe, add the sample of twice this quality again; Each reality of defeating of all use 80N, take out according to circumstances then or the interpolation sample so that sample apart from mouth of pipe 15mm level, is confirmed used sample total amount; Subordinate phase is with 1/3rd of the material mass of confirming in the phase one preparation routine pack into steel pipe and compacting; In steel pipe, add the sample of twice this quality again; Each reality of defeating of all use 80N is taken out according to circumstances then or is added sample so that sample apart from mouth of pipe 15mm level, is tested used solid masses is sample mass definite in the subordinate phase at every turn; With the sample of this quantity part steel pipe of packing into that classifies in three categories, per 1 equal portions all are compressed into 9cm
3
Liquid or colloid sample:
Liquid or colloid sample are filled to apart from mouth of pipe 60mm place, answer SC in case form bubble during the dress colloid;
With coat on the screw shell be the lubricating oil of base-material with molybdenum disulfide after, be set on the steel pipe from its lower end, insert suitable orifice plate and nut tightened, and guarantee not have sample to remain between flange and the orifice plate or stay in the screw thread;
During with the orifice plate of aperture 1.0mm to 8.0mm, should use the nut of 10.0mm, when with the orifice-plate type of aperture greater than 8.0mm, should use the nut of 20.0mm, each steel pipe can only use once, orifice plate, screw shell and nut as do not have damage reusable;
Steel pipe is clipped on the fixing bench vice; Tighten nut with spanner; Then steel pipe is suspended between two rods in the guard box, the test block is depleted of, open the gaseous fuel supply; Burner is lighted, arrived the time of reaction and the extra data that reaction duration can be provided for explanation results; If steel pipe does not break, should continue heating and just finish test at least in 5 minutes, after each test,, should collect overweight if steel pipe breaks;
Test begins test from the orifice plate of 20.0mm, as observes " blast ", and just use does not have orifice plate and nut but has the steel pipe (aperture 24.0mm) of screw shell to make an experiment; As be " not having blast "; Just use (12.0-8.0-5.0-3.0-2.0-1.5) mm and the last 1.0mm of use orifice plate to continue to do disposable test; Till some orifice plates obtain " blast "; Make an experiment with the increasing orifice plate in aperture to order according to 4.3 then, till carrying out three tests with same aperture and all obtaining " do not have blast ", the limit diameter of material is the maximum diameter of hole that obtains " blast " result; If the result who obtains with 1.0 mm dias is not blast, limit diameter is recorded as less than 1.0 millimeters.
If limit diameter is 1.0 millimeters or bigger, the result is "+", that is material heats certain effect of demonstration under sealing condition; If limit diameter is less than 1.0 millimeters, the result is "-", that is material heats not demonstration effect under sealing condition.
Can pick out down column effect:
O: steel pipe no change;
A: steel pipe bottom protrusion;
B: steel pipe bottom and tube wall are protruding;
