Why can't the oil stains on blind holes and threaded holes be thoroughly cleaned? This is not only because the cleaning techniques were not mastered properly, but also closely related to the quality of the chemical degreasing powder. In this article, we will analyze the logic behind this. First, we will discuss the sources of the oil stains on blind holes and threaded holes, and then we will talk about the solutions.
The sources of dirt in the threaded holes and blind holes are as follows:
（1）There is oil residue inside the screw holes (which was brought in during the machining process)
During electroplating, the oil stains dissolve and spread out, forming a bright-colored (nickel) or black (zinc) coating that is wide at the bottom and pointed at the top around the screw holes (especially above the screw holes). The coating is not thick and has poor adhesion. Sometimes, it will fall off slightly when subjected to external forces.
(2) There is still stubbornly remaining oil residue inside the blind hole.
The oil stains in blind holes and deep holes are difficult to clean thoroughly because the traditional alloy chemical degreasing products have poor emulsification performance.
So, is there any solution? You can use Bigely chemical degreasing powder BC-1103. It is a chemical degreasing product that has been carefully selected from a variety of solid detergents and surfactants, and has undergone thousands of formula screenings before being compounded. Its ability to emulsify and break down oil stains is strong. When combined with ultrasonic cleaning, it can quickly remove oil stains in blind holes and deep holes.
