金屬噴涂加工廠家淺析哪些因素會影響金屬噴涂的噴砂機噴砂效果

噴(pen)涂(tu)加(jia)(jia)工(gong)的(de)(de)工(gong)具(ju)不止是(shi)一種，有(you)些噴(pen)塑加(jia)(jia)工(gong)廠(chang)家(jia)還會用(yong)噴(pen)砂機進行(xing)噴(pen)砂。工(gong)件(jian)表(biao)面(mian)(mian)的(de)(de)粗(cu)糙(cao)程度和零(ling)件(jian)材料的(de)(de)強度和硬度有(you)關，和機器的(de)(de)噴(pen)砂直徑(jing)，噴(pen)砂的(de)(de)角(jiao)度等都有(you)很(hen)大的(de)(de)關系。零(ling)件(jian)材料的(de)(de)強度越(yue)高，表(biao)面(mian)(mian)的(de)(de)硬度值就會越(yue)高，這樣噴(pen)涂(tu)出來(lai)的(de)(de)產品他的(de)(de)塑性變形(xing)就變得(de)越(yue)困難。噴(pen)砂對于表(biao)面(mian)(mian)的(de)(de)研(yan)磨作用(yong)來(lai)說還是(shi)起(qi)到(dao)比(bi)較大的(de)(de)作用(yong)的(de)(de)。噴(pen)砂后(hou)表(biao)面(mian)(mian)越(yue)粗(cu)糙(cao)，零(ling)件(jian)的(de)(de)表(biao)面(mian)(mian)會越(yue)平滑(hua)。
