Description
Technical field
The invention belongs to technical field of ceramic material, it is related to a kind of impact resistance and anti-wear performance to wearable ceramic ball
The method for carrying out test evaluation.
Background technology
The wearable ceramic ball of current China's production belongs to low grade products compared with internationally recognizable like product, lacks international
Competitiveness, Main Gaps be it is inside and outside inconsistent, i.e. what the diameter that one layer of smaller, this layer of abrasion on surface grinds off and be transformed into diminished
Porcelain ball milling consumption is just too big.Reflecting the index of wear-resistant ball quality at least will simultaneously meet three requirements：Wear-resisting, impact resistance, inside and outside
Unanimously.
Building material industry standard《Wear-resisting alumina ball》The impact resistance that JC/T 848.1-2010 specify and wear test side
Method：With the grinding jar that internal diameter is 200mm, liner polyurethane, 80 revs/min of rotating speed, speed of related movement is not between such ball and ball
More than 0.837m/s.Traditional 92 aluminium wear-resistant ball that the method is suitable for determining applicant's production (surveyed hundreds of batches of product abrasions to exist
In the range of 0.108-0.293g/kgh).But with the method applicant's quasi- nano wearproof test-manufactured successful in the recent period is determined to aoxidize
During aluminium ball, measurement result is shown as that flawless nothing is crushed, is judged to that impact resistance is qualified, and it is 0.0003g/kgh to wear away, this number
Value is close to zero, therefore it is considered that the method rotating speed is too low, grinding jar intensity does not reach requirement, rubbing suffered by porcelain ball in assay method
Wipe too weak with effect of impact, be unsuitable for determining quasi- nano wearproof alumina balls or similar high abrasion, the porcelain ball of high-impact.
The content of the invention
In order to overcome the shortcomings of assay method in the prior art, the present invention provides a kind of measure wearable ceramic ball crushing strength
With the method for abrasion, can effectively determine the crushing strength of wearable ceramic ball and abrasion, accurate measure go out wearable ceramic ball it is wear-resisting,
Impact resistance and the index of inside and outside uniformity.
It is characterized in that：5-10 porcelain ball is taken for sample, with single bulb diameter d of vernier caliper measurement, radius r is calculated
(mm)；Single ball is put into mould middle part, testing machine pressing plate center is put in together with mould, even ground is with 5mm/min-
The speed loading of 20mm/min or 0.5kN/min-2.5kN/min, reads the pressure value F (kN) when sample is destroyed, and calculates its calculation
Art average value is used as crushing strength：Crushing strength P=(F/ π r2) x1000 (MPa)；It is special with Quick ball grinder and volume 1L
Grinding jar, to the built-in 500g water of grinding jar and 200g porcelain balls, is ground 3 hours with 480r/min, ball is rinsed well, 200 DEG C dry 30 points
Clock to drying, taking-up is weighed；
Abrasion=[(weight after weight-mill before mill)/(weight × 3h before mill)] × 1000 (g/hkg)；
Tested sample repeats grinding five times, surveys abrasion and is arranged by the order for the first time to the 5th time, according to abrasion values
Fluctuating range judges uniformity inside and outside porcelain ball.
The present invention can effectively determine the index of wear-resisting wearable ceramic ball, impact resistance and inside and outside uniformity.Through five tests
Afterwards, if porcelain ball is flawless, fall porcelain without broken, nothing, show that impact resistance is good.
Specific embodiment
Embodiment
Crushing strength is tested：Reference《HG/T 3683.1-2014 industrial porcelain ball inert ceramic balls》The crushing strength experiment of record
Method, is tested with the full-automatic constant stress pressure testing machine of Wuxi building materials testing machinery plant DYE-600 types, takes 7 kinds of porcelain balls, Mei Zhongqu
5 porcelain balls are sample, with single bulb diameter d of vernier caliper measurement, calculate radius r (mm)；Single ball is put into mould middle part, even
Testing machine pressing plate is put in mould to hit exactly, even ground is loaded with the speed of 15mm/min, read pressure when sample is destroyed
Value F (kN), calculates its arithmetic mean of instantaneous value as crushing strength (also known as compression strength)：Crushing strength P=(F/ π r2) x1000
(MPa)；Specific determination data is shown in Table 1.
1 seven kinds of crushing strengths of porcelain ball sample of table
Abrasion test：Wearability is characterized to wear away, this experiment Zibo Randt's fine ceramics Co., Ltd YMJ1 types
Quick ball grinder and corundum grinding jar determine six kinds of abrasion of porcelain ball sample, are the built-in 500g water of grinding jar and 200g porcelain of 1L to volume
Ball, using 480 revs/min of grindings 3 hours as a milling time, ball is rinsed well, dry 200 DEG C dry 30 minutes to drying,
Taking-up is weighed；
Abrasion=[(weight after weight-mill before mill)/(weight × time before mill)] × 1000 (g/hkg)
Tested sample repeats grinding five times, surveys abrasion and is arranged by the order for the first time to the 5th time, and determination data is shown in Table 2
2 six kinds of porcelain ball sample abrasion test datas of table
This experiment：Rotating speed is 480 revs/min, and porcelain ball linear velocity is about 4m/s in tank, than porcelain ball in professional standard grinding jar
Linear velocity is big 3 times；And the rotating shaft of Quick ball grinder is presented eccentric moment 15kgm2/s, so often rotates a circle, tank body is just sent out
Raw secondary eccentric vibration, makes each porcelain ball continually depart from circular orbit and mutually clash into and rub, hitting suffered by such porcelain ball
Hit power and be noticeably greater than suffered impact and frictional force in professional standard grinding jar with frictional force, therefore this method is suitable to determine
Quasi- nano wearproof alumina balls or similar high abrasion, impact-resistant porcelain ball high.
As can be seen here：The quasi- nano aluminium oxide ball milling consumptions of φ 2.5 are minimum, grinding wears away for three times gradually to reduce and shows in it afterwards
Outer uniformity is best；
The accurate nano oxidized aluminium ball wearabilities of φ 13 are slightly inferior to the accurate nano oxidized aluminium balls of φ 2.5 with inside and outside uniformity；
The porcelain balls of Japanese φ 3 are better than the zirconium aluminium balls of Jiangxi φ 13 inferior to accurate nano oxidized aluminium ball；
The alumina balls of roc traditional product φ 13 are inferior to the zirconium aluminium balls of Jiangxi φ 13；
The abrasion of the porcelain balls of Jing Dezhen φ 13 first three time grindings successively linearly increase, the 5th grinding abrasion be increased dramatically it is i.e. interior
Outer uniformity is very poor.
Compare that Tables 1 and 2 is visible, there is consistent trend between the crushing strength and wearability of Ceramic Balls：Crushing strength
Larger porcelain ball milling consumption is also just smaller.
The above, is only presently preferred embodiments of the present invention, is not the limitation for making other forms to the present invention, is appointed
What those skilled in the art is become the equivalence enforcement for turning to equivalent variations possibly also with the technology contents of the disclosure above
Example.But it is every without departing from technical solution of the present invention content, according to appointing that technical spirit of the invention is made to above example
What simple modification, equivalent variations, still falls within the protection domain of technical solution of the present invention.
