PEE *** is applied in steel-plastic composite reactor

The steel-plastic composite reaction kettle made by polyetheretherketone (PEEK) powder spraying technology is superior to traditional glass-lined reactors in terms of high temperature resistance and strength, and is expected to replace precious metal equipment and reduce engineering cost.

Researchers began to develop the technology of spraying PEEK on metal surfaces. The method of spraying the surface of metal products with PEE *** was developed and won the national invention patent this year. At present, the researchers are in-depth research and development of the use of PEE *** spray metal surface technology to produce steel-plastic composite reactor, storage tanks, pipe fittings, heat exchangers, towers and other products. Among them, the steel-plastic composite reactor will be launched soon.

It is understood that the maximum operating temperature of the glass-lined reactor currently used by chemical companies is 180 ° C The pressure used is below 0.6 MPa. The bending strength of PEEK material in 200 ~ Clfi inch can be as high as 24MPa, 250 ° C The bending strength and compressive strength can also reach 12 to 13 MPa. Large-size glass-lined equipment usually needs to increase the wall thickness to reduce the amount of deformation, which is not required for PEEK spraying equipment, so the equipment is a device that consumes less steel. At the same time, PEEK also has excellent metal bonding properties.

Experts believe that the application of PEEK spray carbon steel reactor can eliminate the phenomenon of porcelain explosion in the glass-lined reactor, and has the advantages of high temperature resistance, fast heat transfer speed, long service life and low maintenance cost. In addition, the corrosion resistance of this equipment is superior to various precious metals in a variety of environments and can be used to replace precious metal equipment to significantly reduce investment costs. Therefore, companies and experts are looking forward to the research and development of this technology.

An active ingredient (AI) is the ingredient in a pharmaceutical drug that is biologically active. The similar terms active pharmaceutical ingredient (API) and bulk active are also used in medicine, and the term active substance may be used for natural products. Some medication products may contain more than one active ingredient. The traditional word for the API is pharmacon or pharmakon (from Greek: φάρμακον, adapted from pharmacos) which originally denoted a magical substance or drug.

The term active constituent is often chosen when referring to the active substance of interest in a plant (such as salicylic acid in willow bark or arecoline in areca nuts), because the word ingredient in many minds connotes a sense of human agency (that is, something that a person combines with other substances), whereas the natural products present in plants were not added by any human agency but rather occurred naturally ("a plant doesn't have ingredients").

In contrast with the active ingredients, the inactive ingredients are usually called excipients in pharmaceutical contexts. The main excipient that serves as a medium for conveying the active ingredient is usually called the vehicle. Petrolatum and mineral oil are common vehicles.
