Relationship between New Lamborn Wear Parameters and Wear State of Compound
The relationship between the experimental parameters of New Lamburn wear equipment(load,sample speed,slip rate and talc powder falling speed)and the wear state of the compound was studied.By observing the surface abrasion patterns of the compound under different wear parameters,the wear mechanism of rubber was analyzed.The results showed that,there was a high positive correlation between load and wear speed.The sample speed had a high correlation with the wear speed per unit time,but had little correlation with the wear speed per unit distance.The correlation between slip rate and wear speed was relatively high.As the slip rate increased,the surface abrasion patterns of the sample became clearer and the accumulation of wear debris was gradually aggravated.The relationship between powder falling speed and wear speed was relatively complex.When the powder falling speed was below 0.3 cm3·min-1,the correlation between the two was relatively low.When the powder falling speed was 0.3~0.6 cm3·min-1,the wear speed increased with the increase of powder falling speed,and the growth process of wear debris on the sample surface could be observed at this time.When the powder falling speed was above 0.6 cm3·min-1,the wear speed decreased rapidly with the increase of powder falling speed.
