Abstract
The invention provides a paste emulsion explosive density testing method. The paste emulsion explosive density testing method is high in speed and precision, is simple, and is convenient to realize. The paste emulsion explosive density testing method comprises following steps: an electronic balance with a metre full scale of 200g and a precision of 0.1g is taken; a stainless-steel beaker with a diameter of 10cm and a height of 10cm is filled with four fifths of water, and is placed on the electronic balance, and a button marked with tare is pressed; about 30 to 60g of a paste emulsion explosive is weighed, is suspended in water in the stainless-steel beaker on the electronic balance using string, and is completely immersed in water without contacting the wall of the stainless-steel beaker or the air until weight value displayed on the electronic balance is stable, so that an increased weight value is the volume of the paste emulsion explosive based on Archimede's Floating Law; the string is removed, so that the paste emulsion explosive falls to the bottom of the stainless-steel beaker freely, and an increased weight value is the weight of the paste emulsion explosive; the density of the paste emulsion explosive is obtained by dividing the weight of the paste emulsion explosive to the volume of the paste emulsion explosive. Testing can be completed in 20s, and is not limited by sites or weather.
Description
Technical field
The present invention relates to paste emulsion explosive density, specifically paste emulsion explosive density measurement method.
Background technology
Technology at present for paste emulsion explosive density measurement is mainly graduated cylinder method: the paste emulsion explosive getting about 30-60g, the paper being put in a fritter packages, after surveying its weight, then put into the graduated cylinder filling water, in graduated cylinder, the added value of water is the volume of paste emulsion explosive.The method has following shortcoming: the volume time error 1. reading water in graduated cylinder is large, and precision is low; 2. paste emulsion explosive is placed on paper, slow, the bad operation of speed; 3. time-consuming, effort.
CN 201852761 U provides a kind of emulsion [explosive Quick testing instrument, its minute need completed at about 1 minute, at the scene moment change procedure in, test just have uncertain factor to exist, simultaneously by electronic equipment operation, operation of just having no idea when equipment failure.
CN 202230003 U provide a kind of emulsion [explosive analyzer and such scheme basically identical.
The situation of quality instability is easily there is in the Density of Emulsion Explosive pick-up unit that CN 204154597 U provides when detecting.
Summary of the invention
The invention provides a kind of slow for former paste emulsion explosive density measurement speed, precision is low, the deficiency that error is large, special proposition paste emulsion explosive density measurement method.
Technical scheme of the present invention is for this reason: paste emulsion explosive density measurement method, comprises maximum capacity 200g, precision is the electronic scales of 0.1g, it is characterized in that:
First be the peeling of 10cm, the stainless steel cup of high 10cm or glass beaker by diameter, the water filling 4/5 is placed on electronic scales;
Second step gets the paste emulsion explosive of 30-60g, with cord cream emulsion [explosive is suspended in the stainless steel water in the cup on electronic scales, all flood paste emulsion explosive, require that paste emulsion explosive surrounding must not contact with wall of cup and air, treat that the weight that electronic scales shows is stablized, according to the law of buoyancy its weight increased and buoyancy, be also the volume of paste emulsion explosive;
3rd step: continue above-mentioned paste emulsion explosive all to put in the water of stainless steel cup on electronic scales or glass beaker, at the bottom of now paste emulsion explosive freely sinks to glass, its weight increased is the weight of paste emulsion explosive;
4th step: the weight of calculating paste emulsion explosive, divided by the value of volume gained, is the density of paste emulsion explosive.
Beneficial effect:
Paste emulsion explosive density measurement method of the present invention, has the advantages that test speed is fast, precision is high, simple, and equipment used is simple, nontoxic, and use procedure is to contact personnel and environmentally friendly.
Can survey in 20 seconds, and not be subject to the restriction of place and weather.
Embodiment
The present invention detects according to following steps.
Paste emulsion explosive density measurement method, comprises maximum capacity 200g, precision is the electronic scales of 0.1g,
First be the peeling of 10cm, the stainless steel cup of high 10cm or glass beaker by diameter, the water filling 4/5 is placed on electronic scales;
Second step gets the paste emulsion explosive of 30-60g, with cord cream emulsion [explosive is suspended in the stainless steel water in the cup on electronic scales, all flood paste emulsion explosive, require that paste emulsion explosive surrounding must not contact with wall of cup and air, treat that the weight that electronic scales shows is stablized, according to the law of buoyancy, its i.e. buoyancy of gaining in weight, is also the volume of paste emulsion explosive; Cord volume can be ignored.
3rd step: continue above-mentioned paste emulsion explosive all to put in the water of stainless steel cup on electronic scales or glass beaker, at the bottom of now paste emulsion explosive freely sinks to glass, its weight increased is the weight of paste emulsion explosive; Cord weight can be ignored.
4th step: the weight of calculating paste emulsion explosive, divided by the value of volume gained, is the density of paste emulsion explosive.
Use Archimedes' principle in the process, what adopt is that the mode that paste emulsion explosive does not overflow water in cup measures, water that is to say common tap water, easy to detect passable, precision is accurate, facilitates the instant i.e. use in the production line of paste emulsion explosive, controls the quality of product at any time, can survey in 20 seconds, and not be subject to the restriction of place and weather.
