Liquid or gaseous oxygen system components are often soiled during manufacturing and must be cleaned and dried prior inspection, assembly and packaging. The slightest contamination or residue left on the systems’ moving parts may cause friction. This friction could produce enough heat that when combined with access to a fuel source (residue) could combust, auto-ignite…
This is another application where MicroCare cleaners really shine. “Particulate removal” processes are generally called displacement cleaning.The unique circumstances of this application are found in instances when the contamination is not soluble in any solvent. This happens more often than you might think: solder balls, metal finings, dust and grit all are examples of contamination…
How well a fluid will clean depends on several variables including:the contaminationthe selected solventthe applicationthe cleaning systemthe physical shape of the parts being cleanedWhen is pH a Good Enough Measure?While the pH of a cleaning fluid can be a good indicator of a fluid’s cleaning strength, the pH test only works for fluids containing water.…
Kb value refers to a standardized ASTM test that measures the relative strength of a non-aqueous cleaning fluid. The test involves measuring the solubility of a very specific type of contamination, called “kauri gum.” Kb values range from 10 (very mild) to 200 or even higher (very strong). Mild solvents with lower Kb values will may not…
That’s a great question. In general, modern solvents are neither acid nor alkaline, they are neutral.However, old-style chlorinated solvents like 1,1,1, TCE, perc, nPB and methylene chloride could literally turn acidic (into hydrochloric acid) if the solvents were exposed to too much water and heat. This always was a mess.When a system “went acid” the solvent…
Vapor degreasing is an essential surface cleaning process, widely utilized across various industries. This method uses vapor degreaser machines, and employs solvents in vapor form to effectively cleanse workpieces, preparing them for subsequent finishing operations, such as painting or welding.This guide provides an in-depth look at the vapor degreasing process, its applications, and best practices…
