Abstract
The invention discloses a quantitative testing method for mechanical iron fillings in a power ceramic raw material. The characteristic technology scheme is that a magnet bar is put in a sealed bag and is suspended in the middle water level of a water vessel, which is mixed with powder ceramic raw material. The powder raw material is mixed by a hand and is made to be completely suspended and dispersed in water. The mechanical iron in the raw material is absorbed to the magnet bar until the magnet bar does not absorb mechanical iron fillings. Then, the weight of the absorbed iron fillings is recorded after being cleaned and weighted. At last, the content of the mechanical iron fillings in the sampling powder ceramic raw material is worked out according to a calculation formula. The invention can quantitatively measure the content of the mechanical iron fillings in the powder ceramic raw material and has the advantages of simple process and convenient operation.
Description
Technical field
The present invention relates to the Production of Ceramics field, more particularly relate to the quantitative measuring method of machinery iron bit in the powder ceramic material.
Background technology
At present, the production technology of every quality product more complicated all in the Production of Ceramics, different product needed is processed according to different prescriptions, in blending process, generally all to pass through operations such as grinding, mixing, stirring, but the complexity that the number percent of each composition of monitoring seems suitable in the raw material after stirring as the quantitative test to machinery iron bit in the powder ceramic material, does not also occur in the prior art.
Summary of the invention
Purpose of the present invention is exactly provide for the deficiency that solves prior art a kind of not only simple to operate, and the quantitative measuring method of machinery iron bit in the powder ceramic material of convenient test.
The present invention adopts following technical solution to realize above-mentioned purpose: the quantitative measuring method of machinery iron bit in a kind of powder ceramic material is characterized in that it comprises following processing step:
A, sampling, the powder ceramic material that weighing 100g has been dried places the water receptacle that tap water is housed;
B, bar magnet packed into is suspended in the water receptacle water level middle part that is mixed with powder ceramic material in a process in the sealing bag, stir evenly powder raw material with hand and make its abundant suspended dispersed in water, mechanical iron in the raw material fully is adsorbed onto on the bar magnet, repeats to stir evenly and the machinery iron bit that adsorbs in the raw material no longer adsorbs machinery iron bit to bar magnet;
C, clean, weigh, the bar magnet surface is cleaned with static clear water, the iron filings of absorption are put together, place on the pan paper, put into drying baker and dry, cool off weighing, be designated as W1;
D, calculate machinery iron bit content in the powder ceramic material according to computing formula.
As further specifying of such scheme, in the described d process in the powder ceramic material computing formula of machinery iron bit content be: iron filings %=(W1-pan paper heavy) * %.
The number of times that repeats in the described b process to stir evenly and adsorb the machinery iron bit in the raw material is 4～10 times.
Described water receptacle employing capacity is 3～5 liters a vinyl disc.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is: the present invention adopts the bar magnet sealing bag of packing into to be suspended in the water receptacle water level middle part that is mixed with powder ceramic material, stir evenly powder raw material with hand and make its abundant suspended dispersed in water, make the mechanical iron in the raw material fully be adsorbed onto on the bar magnet, till no longer adsorbing machinery iron bit on the bar magnet, then through cleaning, the operation of weighing, the weight of the iron filings of record absorption, can calculate the content of machinery iron bit in the sampling powder ceramic material at last according to computing formula, simple to operation.
Embodiment
As shown in Figure 1 and Figure 2, the quantitative measuring method of machinery iron bit in a kind of powder ceramic material of the present invention, it comprises following processing step:
A, sampling, the powder ceramic material that weighing 100g has been dried places the water receptacle that tap water is housed;
B, bar magnet packed into is suspended in the water receptacle water level middle part that is mixed with powder ceramic material in a process in the sealing bag, stir evenly powder raw material with hand and make its abundant suspended dispersed in water, make the mechanical iron in the raw material fully be adsorbed onto on the bar magnet, repeat to stir evenly and adsorb machinery iron bit 4～10 times in the raw material, till no longer adsorbing machinery iron bit on the bar magnet;
C, clean, weigh, the bar magnet surface is cleaned with static clear water, the iron filings of absorption are put together, place on the pan paper, put into drying baker and dry, cool off weighing, be designated as W1;
D, calculate machinery iron bit content in the powder ceramic material according to computing formula, machinery iron bit cubage formula in the powder ceramic material: iron filings %=(the W1-pan paper is heavy) * %.
Described water receptacle employing capacity is 3～5 liters a vinyl disc, and bar magnet is 6000 Gauss's bar magnets, and the diameter of this bar magnet is 2.2cm, and length is 6.8cm, and sealing bag is of a size of 16cm * 10cm, and the precision of electronic balance is 0.0001g.
Principle of work of the present invention is as follows: with pack into sealing bag and be suspended in the water receptacle water level middle part that is mixed with powder ceramic material of bar magnet, stir evenly powder raw material with hand and make its abundant suspended dispersed in water, make the mechanical iron in the raw material fully be adsorbed onto on the bar magnet, till no longer adsorbing machinery iron bit on the bar magnet, then through cleaning, the operation of weighing, the weight of the iron filings of record absorption, the last content that can calculate machinery iron bit in the sampling powder ceramic material according to computing formula.
As previously discussed, only be preferred embodiment of the present invention, be not to be used for limiting scope of the present invention, those skilled in the art also can do numerous modifications and variations, under the spirit that does not break away from invention, all in the claimed scope of the present invention.
