Process Control of Aluminum Alloy Extinction Electrophoresis

Process Control of Aluminum Alloy Extinction Electrophoresis

Electrophoresis has been increasingly widely used in various fields such as analytical chemistry, biochemistry, clinical chemistry, toxicology, pharmacology, immunology, microbiology, and food chemistry. The matte electrophoretic coating of aluminum alloy is applied on the surface of the anodic oxide film. Similar to bright electrophoresis, its production process is as follows: Degreasing → water washing → alkaline corrosion → water washing […]

Tool coating technology

Tool coating technology

A certain film is formed on the surface of the tool by chemical or physical methods (ie coating process), so that the cutting tool can obtain excellent comprehensive cutting performance, thereby meeting the requirements of high-speed cutting; since the advent of hard-coated tools in the early 1970s , Chemical vapor deposition (CVD) technology and physical vapor deposition (PVD) technology have […]

New technology of zinc-nickel alloy wastewater treatment

New technology of zinc-nickel alloy wastewater treatment

Electroplating zinc-nickel alloy refers to the formation of a coating film on the surface of the plated parts at a ratio of zinc to nickel 9:1. This protective coating has developed rapidly in recent years due to its excellent corrosion resistance and is widely used in automobiles, aviation, electronics and other industries. Following the rapid development is the increase in […]

What are the characteristics of plastic?

What are the characteristics of plastic?

Plastic is a polymer compound that is polymerized by monomer as raw material through addition polymerization or polycondensation reaction. It is commonly known as plastic or resin. The composition and shape can be freely changed. It is composed of synthetic resin and fillers, plasticizers, stabilizers, and lubricants. , Pigment and other additives. The main component of plastic is resin. Resin […]

Introduction of hot-dip galvanizing and its advantages

Introduction of hot-dip galvanizing and its advantages

Hot-dip galvanizing (hot-dip galvanizing) refers to the method of immersing the plated fasteners in liquid metal zinc or its alloy for plating. Hot-dip galvanizing is widely used to protect steel and its parts from atmospheric corrosion, and is especially suitable for mass production of standard parts and fasteners. Hot-dip galvanizing of fasteners has the following characteristics: ⑮A thick coating can […]

The Pollution prone List Of Mechanical Machining Caused

The Pollution prone List Of Mechanical Machining Caused

Machining is currently undergoing rapid development. In addition to knowing the problems that need to be paid attention to in machining and the causes of errors in machining, the machining staff in this field must also understand the pollution that machining is prone to produce, so as to optimize treatment and reduce environmental impact. The pollution of the world contributes […]

Classification and application scope of ASA and ABS

Classification and application scope of ASA and ABS

Eight precautions for stainless steel welding 1. Chromium stainless steel has certain corrosion resistance (oxidizing acid, organic acid, cavitation), heat resistance and wear resistance. It is usually used for power station, chemical, petroleum and other equipment materials. The weldability of chromium stainless steel is poor, so attention should be paid to the welding process and heat treatment conditions. 2. Chromium […]
