Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete introduction is carried out to the present invention.
Fig. 1 is the side sectional view of one embodiment of the invention; Fig. 2 is the top view of one embodiment of the invention.
As depicted in figs. 1 and 2: Constant-temperaturehigh-pressure high-pressure water-bath kettle, comprise housing 10, pot cover 11, water tank 1, kerve 12, ball-cock assembly level control switch for water 2, pressure limiting valve 6, steam vent 7, heater 8, baffle plate 3, specific gravity bottle fixture 5 and outlet pipe 9, in the present embodiment, described specific gravity bottle fixture 5 is stone, certainly it also can be specific gravity bottle fixed cover etc., described pot cover 11 is arranged on the top of housing 10, the enclosure space of water-bath is formed together with housing 10, described water tank 1 and kerve 12 are positioned at described enclosure space, be communicated with by ball-cock assembly level control switch for water 2, and the height of water tank 1 is higher than the height of kerve 12, to ensure the liquid level of the liquid level of water tank 1 higher than kerve 12, described heater 8 is arranged at the bottom of kerve 12, for heating the water level in kerve 12, baffle plate 3 is also provided with in described kerve 12, for placing specific gravity bottle 4 and specific gravity bottle fixture 5 etc., described specific gravity bottle fixture 5 is for fixing specific gravity bottle 4, prevent its liquid medium dip at kerve 12 or overturning, bottleneck height when the rational height of baffle plate 3 will ensure that the highest liquid level in kerve 12 is positioned on baffle plate 3 lower than specific gravity bottle 4, outlet pipe 9 is then communicated with the bottom of kerve 12, lead to outside through housing 10 simultaneously, in addition, described pressure limiting, valve 6 and steam vent 7 are all arranged on pot cover 11, for controlling the air pressure size in enclosure space.
The present invention in use, puts into Constant-temperaturehigh-pressure high-pressure water-bath kettle specific gravity bottle 4, is controlled the liquid level in water-bath by ball-cock assembly water level switch 2, automatically adds the water in water tank 1, can be improved air pressure and the water temperature of water-bath inside by pressure limiting valve 6.When pressure limiting valve 6 is come by the air pressure jack-up in confined space, water under high pressure bath air pressure inside size then meets: P × S+mg=P' × S, and the boiling point of water temperature i.e. water, relevant with atmospheric pressure, is generally no more than 120 DEG C.Wherein, P is outside atmosphere pressure, and S is the cross-sectional area of pressure limiting valve 6, and m is the quality of pressure limiting valve 6, the g atmospheric pressure that to be 9.807665m/s*s, P' be in water-bath.
Concrete real density detection method is:
With the specific gravity bottle 4 of 25ml, first clean with distilled water, dry, with sensibility reciprocal be ten thousand/gram balance weigh the quality m of specific gravity bottle
1; Get the sample of having dried and put into specific gravity bottle 4, sample charge weight is about 1/3 of volume, and quality control of the experiment, at 4.5-5.0g, weighs up the quality m of specific gravity bottle 4 and sample
2; In specific gravity bottle 4, inject distilled water, reach 2/3 of volume, place in the present invention, boil in hot bath, the bubble that removing sample adheres to.Before boiling, water tank 1 middle water level will expire, boiling time 1 hour.After leaving standstill cooling, then fill distilled water to proportion bottleneck, beyond the Great Wall bottle stopper, water is overflowed from the capillary bottle stopper, just illustrate in specific gravity bottle 4 and fill water, dry the moisture outside specific gravity bottle 4, the quality claiming specific gravity bottle 4, sample and water is m
3; From specific gravity bottle 4, pour out water and sample, after cleaning, fill distilled water, claim the quality m of specific gravity bottle 4 and water
4.
Its computing formula is as follows:
In formula: ρ
o---the real density of material, g/cm
3;
M
1---the quality of specific gravity bottle, g;
M
2---the quality of specific gravity bottle and sample, g;
M
3---the quality of specific gravity bottle, sample and water, g;
M
4---the quality of specific gravity bottle and water, g;
The density of ρ '---medium, g/cm
3.
Tradition real density test (with reference to JB/T5893.5-1991 electroceramics raw material physical property test method) boiling time needs 4 hours, this experimental technique boiling time is short, improve operating efficiency and boil because this experimental technique takes HTHP, gas inside easier emptying powder solid, experimental error is less, and the degree of accuracy is also higher.
The present invention is illustrated according to above-described embodiment, should be appreciated that above-described embodiment does not limit the present invention in any form, and all employings are equal to replacement or the technical scheme that obtains of equivalent transformation mode, all drop within protection scope of the present invention.
