One such process, electroplating, is particularly sensitive to part cleanliness, as even thin layers of oil can hinder coating adhesion. Cleaning methods encompass solvent cleaning, hot alkaline detergent cleaning, electro-cleaning, and acid etch. In industrial settings, the water-break test is a common practice to assess machinery cleanliness.
Only in rare and catastrophic cases, do oil and gas wells come in with a fountain of gushing oil. In real life, that is a blowout —and usually also a financial and environmental disaster . But controlling blowouts has drawbacks—mud filtrate soaks into the formation around the borehole and a mud cake plasters the sides of the hole.
Parts washers were originally developed for use in automotive transmission and engine repair shops as a way to improve the function of simple soak tanks.Soak tanks are vats filled with a mixture of water and detergent, which take hours to "soften" the built-up road grime, fluids, tars and oils enough to be manually rinsed off prior to disassembly and repair.
Accuracy of measurement when using a caliper is highly dependent on the skill of the operator. Regardless of type, a caliper's jaws must be forced into contact with the part being measured. As both part and caliper are always to some extent elastic, the amount of force used affects the indication. A consistent, firm touch is correct.
One advantage of scraping is the ability to take the tool to the workpiece; this can be useful when the workpiece weighs several tons and is difficult to move. It is done by using a precision surface such as a surface plate or a straightedge as a standard (a straightedge in this context is not a ruler; it is a miniature surface plate of extreme ...
The new labels rules, for instance, add salmon, eggs, olive oil, nuts and whole grains to the list of "healthy" foods and remove foods with high amounts of added sugars.
Oil sampling is a procedure for collecting a volume of fluid from lubricated or hydraulic machinery for the purpose of oil analysis. Much like collecting forensic evidence at a crime scene, when collecting an oil sample, it is important to ensure that procedures are used to minimize disturbance of the sample during and after the sampling process.
Manufacturers of baby powder and cosmetic products made with talc will have to test them for asbestos under a proposal announced by the U.S. Food and Drug Administration.
