Analysis of methods for assessing the quality of cleaning repair object

Abstract

EN: During machine repair, cleaning restored objects of operational and technological contaminants is crucial. Surface cleaning involves the removal of liquid and solid contaminants to a specific cleanliness level. Based on the physical and mechanical properties of machine contaminants and their components, contaminants can be conventionally divided into three groups by the complexity of their removal: I – road-soilcontaminants, fuel-lubricant residues, metal shavings, abrasives, etc; II – aged grease, oils, residues of cleaning agents, pastes, and mastics; III – asphalt-tar deposits, carbon deposits, scale, corrosion products, and old paint coatings. Specific technologies are developed to remove each group of contaminants. Cleaning operations result in achieving a certain surface cleanliness level, making research into effective methods for objectively evaluating cleaning quality relevant
