I. Industry Background: Why Cleaning of Automotive Engine Components Matters
During automotive engine production, machined components such as cylinder blocks, cylinder heads, crankshafts and connecting rods are covered with large amounts of contaminants including cutting fluid, processing oil and metal chips. Inadequate cleaning will compromise subsequent assembly accuracy, cause wear on mating surfaces and even trigger premature engine failures. Therefore, component cleaning is an indispensable critical process in engine manufacturing.
Meanwhile, cleaned workpieces require short‑term rust protection during inter‑process transfer and temporary storage to prevent oxidation and rust on metal surfaces. Traditionally, cleaning and rust prevention are two separate operations. CP‑60B combines cleaning and short‑term rust‑preventive functions into one product to simplify process workflows.
In addition, aluminum alloys are widely used for engine parts such as cylinder blocks and cylinder heads, which requires cleaners to be non‑corrosive and non‑discoloring to aluminum. Strong‑alkaline cleaners tend to corrode aluminum parts. Hence, mild‑alkaline water‑based cleaners have become the mainstream option for automotive engine component cleaning.
II. Product Description
CP‑60B is an organic‑based mild‑alkaline water‑based general‑purpose cleaner for component cleaning and short‑term rust prevention in automotive engine production. It works at ambient temperature, and its degreasing capacity increases significantly upon heating. It effectively removes processing oil, cutting fluid and various grease contaminants from workpiece surfaces, while providing short‑term rust protection for ferrous metals and cast iron.
No white residue remains after blow‑drying, meeting strict cleanliness requirements for engine components. It is non‑corrosive and will not cause discoloration to non‑ferrous metals like aluminum, and can be safely adopted in cleaning processes for multiple metal materials. Compatible with immersion, spray and ultrasonic cleaning processes, it gives full play to the performance of existing equipment.
