The invention belongs to the technical field of zirconia ceramic detection, and particularly relates to a rapid detection method for abrasion of zirconia beads.
[ background of the invention ]
At present, with the development of modern manufacturing technology towards high technology, a large number of novel ceramic grinding media, i.e. high-performance ceramic balls and microbeads, are required. The main reason is that the ceramic balls and the microbeads are mostly white, and have the advantages of high strength, high hardness, wear resistance, corrosion resistance, high specific gravity, high efficiency and the like. Therefore, the application of the ceramic balls and the micro-beads in many fields such as special ceramics and other inorganic non-metallic materials, biopharmaceuticals, mechanical parts, plastic product polishing and the like is more and more extensive at home and abroad. For example: the bearing ball, the ball valve core, the ornaments, the paint, the pigment, the printing ink, the titanium pigment, the kaolin, the white cement, the electronic slurry, the glaze, the ultrafine powder and the nanometer powder of various ceramic materials and the like are used in many occasions. At present, some manufacturers in China use high-performance ceramic balls and microbeads manufactured in Korea, Japan and other countries. Therefore, the high-performance ceramic balls and the micro-beads are researched, manufactured and applied to replace imported products, and the method has good social and economic benefits. This has to be picked up first from the zirconia proof mass.
The detection of the abrasion performance of the zirconia beads is an embodiment of the comprehensive mechanical performance of the zirconia beads, and for manufacturers with zero pollution requirements, the requirements on the abrasion performance of the zirconia beads are particularly high, and the existing methods for testing the abrasion of the zirconia beads are various: 1) grinding with a material by a sand mill, for example, the sand mill is matched with a certain material to be ground, and the zirconium bead abrasion is judged by grinding the material to a specified particle size within the same time and the abrasion loss, although the method is an evaluation method closest to the sanding working condition, the required sample amount is more than 10-20 kg, and the ground sample cannot be sold to a customer as a product because the surface of the sample is rough; 2) the planet grinding belt material mill, about one kilogram of grinding balls, a proper amount of water and grinding materials, such as alumina and the like are taken, grinding is carried out for a proper amount of time, and the ball milling effect is better and worse compared with the loss of weight of zirconia; 3) a sand mill or a planetary mill is used for directly and purely grinding a sample for 100 hours or more, so that the abrasion of zirconia beads is judged by weighing the weight loss of zirconia, the zirconia beads can be continuously sold to customers as products, but in the operation process, particularly, small balls are difficult to avoid loss, the mass loss is small, and the electronic scale has certain errors, so that the weighing range of the electronic scale with higher precision is limited, and the abrasion data of the electronic scale is difficult to be used as a reliable value of abrasion to evaluate the abrasion conditions of zirconium beads in different batches. The invention provides a zirconium bead abrasion testing method which can qualitatively judge the abrasion of zirconium beads, is simple and quick, has zero pollution to a zirconium bead sample and has minimum damage to the zirconium beads.

[ detailed description ] embodiments
In order to make the technical solution of the present invention clearer, the following describes an embodiment of the present invention in further detail with reference to the accompanying drawings.
The invention provides a rapid detection method for abrasion of zirconia beads, which comprises the following specific detection steps as shown in figure 1:
s1, sampling and canning, selecting an electronic scale with the precision of more than 0.01g, after calibration, putting the cleaned MC nylon ball milling can on the electronic scale for weighing, and recording the weight as M3Then adding 1 part by mass of deionized water or pure water which can be about 500g into the ball milling tank, recording the weighing weight of the electronic scale as M2Then adding 1.9-2.1 parts by mass of zirconia bead sample which can be about 1kg in mass into the ball milling tank, and recording the weighing weight of the electronic scale as M1M of record2M recorded for weighing after adding water to the jar1The weight of the ball milling tank after adding water and the zirconia bead sample is measured. During the charging, because the zirconia beads, particularly the zirconia microspheres are easy to lose and bounce off in the transferring process, the adding of pure water firstly can play the roles of buffering elasticity and collision force on the added zirconia beads, and thus the charging is realizedThe loss of the zirconium beads in the transfer process can be avoided.
S2, ball milling, namely putting a ball milling tank filled with zirconia beads and deionized water into a ball mill for ball milling, wherein the ball mill is a planetary ball mill, and the ball milling time is controlled to be 20-30 h. Specifically, because the planetary ball milling can be generally provided with a plurality of ball milling tanks at one time, a plurality of samples can be taken for detection at the same time, the plurality of ball milling tanks are filled with the zirconium oxide bead samples and water according to the step S1, then the zirconium oxide bead samples and the water are put into the planetary ball milling machine, the actual rotating speed is adjusted to 300-350 r/min, and then the ball milling time is set to 20-30 h. The ball-milling time of overlength can lead to most water finally all to become muddy, the ball-milling time of overlength can make the water of ball-milling all be limpid basically, so suitable ball-milling time is very critical, the settlement of rotational speed also has the requirement, too high rotational speed can lead to the zirconium pearl centrifugal force too big in the ball-milling jar, adhere to the wall completely, can't let the zirconium pearl play fine autogenous grinding effect, the rotational speed that hangs down makes the autogenous grinding effect of ball-milling weak, lead to the ball-milling time too long, water turbidity is also unchangeable basically.
And S3, abrasion detection is carried out, the ball milling tank is taken out, the turbidity of the water body in the tank is measured through a turbidity tester, and the abrasion level of the zirconia beads is judged according to the turbidity value. Specifically, the turbidity of the liquid in the ball milling tank is detected by a turbidity meter, turbidity data is recorded, the turbidity of the water body is observed by naked eyes, and then the abrasion level of the zirconia beads is qualitatively judged by combining the turbidity data with the table 1. If the sample is slightly turbid or more than the sample in the first measurement, detecting the turbidity once again for confirmation so as to reduce the interference of external factors, if the turbidity of the water body in the second measurement is the same or higher, determining that the first measurement result is accurate, and if the turbidity is reduced, determining according to the second measurement result.
TABLE 1 zirconium bead abrasion evaluation Standard
The abrasion loss levels in the above table 1 were estimated from the average turbidity and abrasion amount formulas of the same amount of zirconium beads in the three kinds of powders in fig. 2.
S4, cleaning, namely putting filter cloth into a stainless steel basin, adding a proper amount of pure water or deionized water, completely transferring the zirconium oxide beads in the ball milling tank into the filter cloth by using a cleaning bottle, stirring by using a glass rod so as to clean the zirconium oxide beads, wrapping the zirconium oxide beads by using the filter cloth, putting the zirconium oxide beads into an ultrasonic cleaning machine, ultrasonically cleaning for 3-7 min, and repeatedly cleaning for 3-4 times until a cleaning water body becomes clear.
S5, drying and weighing, transferring the cleaned zirconia beads to a tray by using a wash bottle, putting the tray on a drying box frame for drying, then opening an electronic scale with the precision of more than 0.01g, and calibrating. Then weighing the zirconia beads on a tray, and recording the weight as M4The zirconia beads in the tray were then transferred in their entirety to a sample bag via a funnel and a large beaker, and the tray was then weighed, the weight of which was recorded as M5Then M is45＝M4-M5。
S6, calculating the abrasion loss delta M of the zirconia beads according to the following abrasion loss formula:
wherein T is ball milling time and the unit is h; m1、M2、M45Unit of (d) is g; the abrasion loss Δ M is expressed in ppm/h.
The fast detection principle of the invention is illustrated as follows: the yttrium-stabilized zirconia powder (i.e. zirconium beads) is used as a sample, and a certain amount of deionized water is used as a solvent, and the result shows that within a certain mass range, the influence of different amounts of zirconia powder on the turbidity of a deionized water body has a positive correlation rule, and different trace amounts of powder are added into a certain volume of deionized water, so that the water body generates different degrees of turbidity after ultrasonic treatment, as shown in fig. 2. The loss of 1kg of zirconium oxide beads which are worn to 0-0.3 g can be easily realized only by adopting simple zirconium bead self-grinding. A similar rule exists for cerium stabilized zirconia powder and zirconium aluminum composite oxide powder according to this operation, as shown in FIG. 2.
Through comparing this kind of law with pure water and zirconium bead autogenous grinding and discovering, the same law also exists, as shown in FIG. 3 specifically, will pass through zirconium bead autogenous grinding for a suitable amount of time, because the zirconium bead particle that grinds down becomes more, can produce different turbidities to the zirconium bead of different wearing and tearing, can clearly be seen from FIG. 3, yttrium-stabilized zirconium bead wearing and tearing are generally the minimum, and cerium-stabilized zirconia bead is followed, and zirconium aluminium composite zirconia bead generally wears and tears the highest. Moreover, as can be seen from fig. 3, the abrasion of the zirconium beads of the same specification is generally larger, and the correspondence between the abrasion and the turbidity is more obvious, which indicates that for the lower abrasion, the yttrium-stabilized zirconia beads and the cerium-stabilized zirconia beads have lost significance in directly judging the abrasion by the abrasion data. The method has the advantages that impurities which affect color and turbidity are not introduced into the ball milling tank body and the deionized water, polished finished zirconium beads which are cleaned up need to be obtained, such as the wear-resistant MC nylon tank is good in effect, balls with any size and balls of any kind can be quickly abraded and classified, but in actual operation, the turbidity value of a water body of the zirconium beads subjected to ball milling is directly used for hardness of the zirconium bead abrasion judgment data, the change of the turbidity of the water body has accidental factors, the turbidity value is divided reasonably according to a certain index range, and the specific division is shown in table 1.
In a word, the method can well distinguish the zirconium beads with high abrasion from the zirconium beads with low abrasion through the operation of the method, and achieves a very good effect.
