珠海勁威科技-硬質(zhì)合金刀具清洗處理和不銹鋼拋光后的清洗方法

一般情況下，拋光膏常常采用石蠟調(diào)合，石蠟分子量大，熔點較高，常溫下呈固態(tài)，是較難清洗的物質(zhì)，傳統(tǒng)的辦法是采用有機(jī)溶劑清洗或高溫堿水煮洗有許多弊病。采用超聲波清洗機(jī)進(jìn)行清洗則可使用水基清洗劑，在高溫條件下浸泡，中溫條件下超聲波，純水進(jìn)行漂洗，循環(huán)熱風(fēng)進(jìn)行干燥處理，這樣一般幾分鐘內(nèi)將工件表面徹底清洗干凈，需要注意的事為不同的拋光產(chǎn)品清洗工藝有所不同。
硬質(zhì)合金是種高生產(chǎn)率的工具材料，是將高熔點、高硬度的金屬碳化物粉末與黏結(jié)劑混合用粉末冶金法壓制成各種所需形狀的工件，在硬質(zhì)合金刀具涂層前，或者焊接前都必須將上面的附著物清洗干凈，否則將無法上涂層，焊接前如果不能把線切割殘留的微小顆粒去除干凈將嚴(yán)重影響焊接質(zhì)量，傳統(tǒng)的清洗主要是用酸性液體直接浸泡，這樣的處理方式對刀具有一定的腐蝕；如果采用超聲波清洗的方式將徹底解決線切割后的殘留問題，但是必須配合專用的清洗劑才能到達(dá)更好的效果；最大的缺點是只能清洗刀具表面的油污，對線切割后的微孔內(nèi)的污垢用處不是很大。
