The recent high temperature coal tar market may rebound from a low level

In the past month or so, the domestic epidemic has broken out, logistics has been restricted, and the circulation of goods around the country has not been smooth. The supply of hig

The global oil market ushered in a recovery, and the industry's prosperity re...

On April 12, the "2021 Domestic and Foreign Oil and Gas Industry Development Report" (referred to as "Industry Report") compiled and managed by the National High-end Think Tank Chi

How Surface Oxidation of Carbon Black Affects Electrical Conductivity

Under the condition of the same surface area and structure, the conductivity of oxidized carbon black is weaker than that of unoxidized carbon black. Since the surface has greater

Factors to consider when choosing to use powdered or granular carbon black

Granular carbon black is easier to store, transport and handle than powdered carbon black. With less dust, it is easier to clean, reducing production management issues. Granular ca

Application of carbon black in fiber coloring

The application of carbon black as a dye in fibers can be directly added in the fiber processing process for dyeing. But at present, the most widely used dyeing method is masterbat

Typical process of carbon black type antistatic and conductive fiber

Typical process of carbon black polyamide antistatic and conductive fiber The preparation process of PAREL II carbon black conductive composite nylon 6 filament is as follows. Add

Carbon black conductive composite polyester PET fiber

① Preparation of conductive polymer PET polyethylene glycol→copolyester→carbon black added to twin-screw mixer→slicing→vacuum drying→solid phase polymerization→cooling→conductive p

Application of Carbon Black in Conductive Fiber

Conductive fibers refer to fibers whose resistivity is less than 107Ω·cm in a standard state. High specific resistance conductive fibers can be used in anti-static work clothes, gl

Application of carbon black in antistatic fiber

Antistatic fibers refer to fibers with resistivity less than 1010Ω·cm in standard state or fibers with electrostatic charge dissipation half-life less than 60s, which can reduce el

Methods for improving and reducing carbon black structure

The structure of carbon black is closely related to the composition and properties of the feedstock oil. The higher the aromatic content in the feedstock, the higher the structure

Surface Properties of Carbon Black

The pH value, volatile matter and diphenylguanidine sorption rate of carbon black are the quality indicators reflecting the chemical properties of carbon black surface. When there

Impurities in carbon black and how to deal with them

Carbon black readily absorbs moisture during the generation, cooling, pelletizing (dry process), packaging, and shipping processes. In order to control the moisture content of carb
