Description
Technical field
The present invention relates to the inspection field of calcium carbonate, especially a kind of calcium carbonate material quality method of inspection.
Background technology
Heavy calcium carbonate powder is to form the direct crushing grinding of calcium carbonate stone, and calcium carbonate stone is natural on mountain
Generation, there can be the association of other non-carbonic acid calcium substances in its generating process, these non-carbonic acid calcium substances can present various
The color and luster of various kinds, and exploiting all can not reject non-carbonic acid calcium substance during calcium carbonate stone.Different mine associations
Thus non-carbonic acid calcium substance causes calcium carbonate material quality difference very big there is also difference.
Calcium carbonate material quality is most important for heavy calcium carbonate powder product quality, is given birth to for heavy calcium carbonate powder
Produce for enterprise, the whiteness of calcium carbonate raw material is to differentiate the important indicator of material quality, is generally acknowledged at present in industry to wear into 400 mesh
The whiteness measured is evaluated material quality and defined the level, and using whiteness 94-95 as two level, 95-96 is one-level, and more than 96 be superfine, is led to
The judgement of the whiteness level of material is crossed, adaptable raw material can be chosen according to the demand of client.
The key for differentiating calcium carbonate material quality is that the fineness that raw material is worn into will be stablized, because influence of the fineness to whiteness is very
Greatly, same sample fineness is thinner, and whiteness is higher, it is therefore desirable to one kind can by calcium carbonate raw mill to 400 mesh and every time
The stable calcium carbonate raw material detection method of fineness of grind.
It is domestic at present be used for experiment small-sized milling apparatus it is a lot, but can by calcium carbonate raw mill to 400 mesh and
The stable milling apparatus of holding fineness of grind is simultaneously few, and some equipment have reached requirement on hardware, but due to no fixed
The reason for operating method and material processing, makes grinding product can not possess stable fineness of grind；And after grinding, if
Many hardened samples are had in standby to be difficult to clean off, and influence testing result next time.Therefore, the enterprise of powdered whiting production at present
Industry without calcium carbonate ingredient inspection, so as to lead to not carry out control to calcium carbonate material quality, causes heavy carbonic acid substantially
Calcium powder body production efficiency declines, and heavy calcium carbonate powder product quality deviation is larger.For the above situation, it is a kind of suitable to choose
Sample preparation grinder, and obtain one kind and by calcium carbonate raw mill to 400 mesh and fineness of grind can be kept stable and ground to set
The standby easy cleaned calcium carbonate material quality method of inspection is the task of top priority.
The content of the invention
In order to solve above-mentioned technical problem present in prior art, the present invention provides a kind of calcium carbonate material quality and examined
Method, it is achieved particular by following technical scheme：
(1) sample treatment：Dried in the cool after calcium carbonate sample is cleaned, be then placed in stainless steel pallet and uniformly spread out
Open, be placed in thermostatic drying chamber, dried 15~20 minutes at (105 ± 5) DEG C, sieved after taking out cooling with 1cm screen clothes；By nothing
The particle of the particle and color especially deep (visually obvious red, black, yellow) of method sieving, which is crushed to, can cross 0.5cm screen clothes, by institute
There is raw material to be well mixed.
(2) sample is ground：Chemical examination system of this programme from the model GJ-500 of analysis and sample making machinery plant of Nanchang City production
Sample grinder is ground, and accurately weighs two glasss of the material sample mixed in step (1), and weight is respectively 150 grams and 200
Gram, the alms bowl of sample preparation grinder is taken out, 150 grams of samples in weigh up two glasss of samples are poured into ring, 200 grams of samples are poured into outside ring,
The calcium carbonate sample mixed is ground to 400 mesh using sample preparation grinder.Sample preferably is weighed using quartering, is made
With sample quarterlies, sample point is few, saves labour, and and can ensures the uniformity and representativeness of sampling.
(3) sample detection：Sample preparation alms bowl is taken out after ground, collects powder loose in sample preparation alms bowl, and press《QHKL
The universal method of the inorganic chemical product measuring brightnesses of J08.002-2014GBT 23774-2009》Detection whiteness simultaneously passes through gained
Sample whiteness according to：Whiteness 94-95 is two level, and 95-96 is one-level, and more than 96 be superfine, to be defined the level to sample.
(4) clear away waste：Block is hit by round and the ring-like block that hits is put back in alms bowl, with sample preparation step operation, weighs 150g respectively
Sample is added in ring, and 200g samples are added outside ring, is stopped grinding after grinding 5-15s, is cleared up sample preparation alms bowl.It is now hardened in sample preparation alms bowl
Sample caused the fragmentation that comes off by the new impact for adding sample, it is easy to clean out, do not have one under the influence of sample carryover
Secondary assay.Preferable milling time should be 10s, and now hardened sample is easiest to clear up, and the time is too short to cause to impact
Not enough fully, the fragmentation that comes off of hardened sample is not thorough enough, and overlong time can then cause the hardened appearance of new sample.
The analysis and sample making grinder for the model GJ-500 that step (2) is produced from analysis and sample making machinery plant of Nanchang City is to mixed
The calcium carbonate sample got togather is ground, and the abrasive body of the sample preparation grinder is diameter about 250mm sample preparation alms bowl, is had in alms bowl
One it is solid it is round hit block and a diameter about 150mm, thickness the ring-like of about 10mm hit block, it is wear-resisting resistance to using special material
Corrosion.
Compared with prior art, the technique effect of the invention is embodied in：
By steps such as the cleaning of sample, sieving, broken, grinding, cleaning sampling machines, especially choose suitable sample preparation and grind
Sample preparation alms bowl after grinding machine and the method processing grinding ground by the short time that feeds again is cleared up it again, and obtaining one kind can
Calcium carbonate sample is uniformly ground to 400 mesh and each fineness of grind is stable；Easily cleaning remains without hardened useless powder, does not interfere with
The calcium carbonate raw material detection method of testing result next time, allows powdered whiting manufacturing enterprise easily before manufacture to carbon
Sour calcium raw material carries out the quality of quality inspection, preferably control calcium carbonate raw material, produces the heavy carbonic acid of suitable customer requirement
Calcium powder product.
