汽車零部件的清潔度測(cè)試The cleaning test of the auto parts
汽車零部件清潔度規(guī)范和標(biāo)準(zhǔn)的建立，涉及到五個(gè)步驟和問題：零件的尺寸，污染物性質(zhì)，清潔準(zhǔn)備，清潔過程和清潔度檢測(cè)驗(yàn)證。
5 steps or questions are involved in this specification: parts dimensions, Nature of the pollutants, cleaning preparation, cleaning process and cleaning verify
一、零件的尺寸parts dimensions
零件的尺寸被看做是設(shè)計(jì)一個(gè)高效的清洗過程的基礎(chǔ)。這要求客戶與清洗設(shè)備制造商保持緊密互通，以了解零部件的精確尺寸，公差和材料組成。材料尤其不能被忽略，因?yàn)樵谇逑催^程中，化學(xué)品會(huì)產(chǎn)生腐蝕，物理清洗會(huì)導(dǎo)致熱膨脹而改變零部件的尺寸。
Parts dimension is the primary of designing a efficient cleaning process.this requires the customer keep good communication with the manufacturer of the cleaning equipment to understand the affection of the dimension, tolerance and material to the cleaning. Should not ignore the raw material as the material may be corroded by the chemical, and the temperature will also change the parts dimension in the cleaning process.
