Description
Technical field
The present invention relates to a kind of oxidisability solid test device, especially relate to a kind of test macro and measuring system can being separated, measuring accuracy is high, the test unit of safe and reliable modified test oxidisability solid.
Background technology
Oxidizing substance is a kind of itself may not burning, but conventionally because emitting oxygen, may cause or impel the material of other oxidation material burnings, and it belongs to the 5th class in Classification of Dangerous Chemicals.The harm of oxidizing substance is many-sided, therefore, before storing and transporting, must identify oxidizing substance, further to its classification, to assess its danger.At present, the domestic and international up-to-date oxidisability solid test method and apparatus adopting is that the responsible < < of the unified classification of the global chemical substance of reference and the labeling system problem Committee of Experts tests about the recommendation of Dangerous Goods Transport and manual of standards > > the 5th edition augments 2.Generally that the determinand potpourri of certain mass is placed on thermal insulation board, and thermal insulation board is directly placed in the enterprising electrical heating test that works of balance, determinand potpourri is because decomposes is burnt, by balance, test the mass change situation of the burning front and back of determinand potpourri, judge whether this determinand is oxidisability solid matter.But the test unit in the method cannot separate test macro and measuring system, and the heat that during test, reaction produces can affect balance measurement, and the larger weight of test macro itself defines palpus wide range while measuring, the balance of low precision.Therefore, need to design a kind of test macro and measuring system can being separated, measuring accuracy is high, and the test unit of safe and reliable modified test oxidisability solid, solves above-mentioned deficiency.
Summary of the invention
Object of the present invention is exactly in order to overcome the defect of above-mentioned prior art existence, to provide a kind of test macro and measuring system to be separated, the test unit of the modified test oxidisability solid that measuring accuracy is high and safe and reliable.
Object of the present invention can be achieved through the following technical solutions: a kind of test unit of modified test oxidisability solid, be provided with test macro and measuring system, it is characterized in that, described test macro and measuring system are positioned at lever system two ends, and connect by lever system;
Described test macro comprises:
Support A: be connected with limited block;
Limited block: be arranged on support A top;
Pallet A: be arranged on lever test one end;

Pallet B: be arranged on lever and measure one end;
Level governor: be arranged on lever and measure one end downside, bottom contacts with balance on goods and services;
Balance: be arranged on pallet B and level governor below.
Solid to be detected is placed on thermal insulation board, and by power supply, it is heated.
Described lever is provided with surveyor's staff, records the mass change of solid to be detected by the weight of adjustment counterweight.Adopt balanced structure, by counterweight, offset the weight of proving installation, can adopt thus the high-precision balance of small-range, select flexibly, to reduce experimentation cost.
Described lever system by support B as fulcrum, by regulating the lever arm length of position adjustments test macro and the lever arm length ratio of measuring system of support B, while can corresponding adjusting measuring weightless increase weight with balance demonstration between ratio.Utilize non-bascule to improve the sensitivity of measuring system.
Between described wire A and wire B, by brush, be connected the measuring error of avoiding the wire power of scratching to cause with collector ring.
Sample directly heating on balance when the present invention can avoid measuring the solid hazardous property of oxidisability, but by having set up a lever system, lever has played very important effect.First, the use of lever separates test macro and measuring system, the heat effects balance measurement that while having avoided test, reaction produces; Secondly, due to the balanced structure of lever, can utilize counterweight to offset the weight of test macro, thereby can use the high-precision balance of small-range while measuring, improve the accuracy of measuring; Again, the lever using in device is non-bascule, the lever arm of test macro part is greater than the lever arm of measuring system part, improve thus the sensitivity while measuring, and can select by the ratio of adjusting two parts lever arm length the balance of different ranges and precision: last, wire is connected with collector ring by the brush at balance pivot place, the measuring error of avoiding the wire power of scratching to cause.Compared with prior art, specifically comprise following advantage:
(1) simple structure, cost is lower;
(2) test macro and measuring system are separated to the heat effects balance measurement that while avoiding testing, reaction produces;
(3) can select small-range, high-precision balance, select various;
(4) non-bascule improves the sensitivity of measuring;
(5) measuring error that the wire power of scratching causes is avoided in the use of brush and collector ring.
