What risks should be avoided in the analysis of media products used in the production of POWDER metallurgy parts?

2021-02-20

In the production and processing will mainly useanti-rust oil, cleaning agent, cutting fluidthree types of products.

Products with different properties are used in different production processes:

Rust-proof oil:

1, sintered after use, requiring high flash point, more than 160 degrees, viscosity of about 10Cst. After sintering, the parts have higher temperature, low flash point anti-rust oil has the risk of ignition, large volatilization and large consumption.

2, the finished product is used for rust prevention, requiring low viscosity and small consumption. Due to the porous internal structure of powder metallurgy parts, the oil absorption is large and the consumption of anti-rust oil is large.

Cleaner:

Under normal circumstances, choose continuous cleaning equipment and antirust oil matching use, choose ultrasonic cleaning mode, choose water-based cleaning agent. The requirement of oil removal ability is strong, under the action of ultrasonic wave, the oil absorption in the pores of the parts is cleaned.

Cutting fluid:

The choice of synthetic cutting fluid for cutting requires excellent rust resistance and settlement performance. Powder metallurgy parts are prone to rust, so it is necessary to shorten the flow time between processes in actual production.

Powder metallurgy parts assembly test machine, there will be smoke problem, mainly due to the rust prevention oil contained in the pores of the parts caused by high temperature combustion volatiles, it is difficult to clean thoroughly.
