我厂在多年生产橡胶初加工机械的实践中,发现易损件辊筒的使用寿命不够理想,磨损快,更换频繁,生产乳胶标准胶2000t左右就需更换,既麻烦,又影响生产。用户要求一个辊筒能使用一年(即生产3000～6000t)。因此,我们对提高辊筒的使用寿命进行了试验研究。 1.辊筒磨损快的原因 橡胶加工机械的辊简绝大部分为球墨铸铁件,磨损快的主要原因有:①硬底低,耐磨性差,当磨损超过辊筒花纹尺寸极限时就报废。②耐蚀性差,长期受潮接触酸碱溶液,造成腐蚀,至使辊筒尺寸变小甚至花纹
I plant in the production of rubber processing machinery for many years in practice, found that the service life of wearing parts roller is not ideal, fast wear, frequent replacement, the production of plastic latex around 2000t need to be replaced, both cumbersome, but also affect the production. Users require a roller can be used for one year (that is, the production of 3000 ~ 6000t). Therefore, we have to improve the service life of the roller test. 1. Roller wear fast reason Rubber processing machinery roller Jane vast majority of ductile iron, wear fast main reasons are: ① hard bottom, poor wear resistance, when the wear exceeds the size of roller pattern scrapped. ② poor corrosion resistance, long-term exposure to acid and alkali moisture solution, resulting in corrosion, even to the smaller roller size pattern
