First, the toner Toner advantage: 1, the price is cheap, affordable. 2, the proofing time is short, the production is fast, and the desired color can be quickly completed. 3. Easy transportation. 4. Suitable for a small variety of products. Toner defect: 1. When the toner is stirred, the pollution is large, and the mixing drum is not easy to clean. 2, different raw materials, different brands or batch numbers and operating conditions are different, machine and mold different operating temperature differences, different ways, will produce color difference. 3. Poor dispersion. Second, the color master Color master benefits: 1, the color is more stable. 2, will not pollute the environment. 3, the price is moderate, the inventory is small. 4. Good dispersion. 5, suitable for central feeding system, long-term orders. Color master disadvantages: 1. There must be a certain amount of production volume of at least 100 kg per batch. 2, must be evenly distributed to prevent static electricity or otherwise produce chromatic aberration. Third, pumping Advantages of pumping: 1, the color is stable, eliminating raw material black spots impurities. 2, easy to operate, automated production does not have to mix materials, increase production capacity. 3. Do not pollute the environment. Difficulties in pumping: 1. The cost is higher than the color masterbatch and the toner. 2. During the pumping process, the physical properties of the raw materials may be reduced. 3. Large inventory and high transportation costs.

Duplex Stainless Steel Overview
Duplex Stainless Steels, also referred to as austenitic-ferritic stainless steels, are a family of grades with about equal proportions of ferrite and austenite. These steels have a duplex microstructure which contributes to their high strength and high resistance to stress corrosion cracking. Due to their high content of chromium, nitrogen and molybdenum, duplex steels offer good resistance to local and uniform corrosion. Duplex stainless steels have good weldability.
Today, modern duplex stainless steels can be divided into three groups:
Of the duplex grades, duplex 2205 is the most widely used. However, the super duplex steels like Zeron® 100 and LDX2507 are excellent for servicing severe corrosive environments, such as offshore and marine applications. Lean duplex 2101 is available as an economic alternative to 300 series stainless steels.
