Silica is a not natural substance and one of one of the most important compounds of silicon. It exists in nature in crystalline types (such as quartz, cristobalite, chalcedony, agate, opal, and so on) and non-crystalline particulate, irregular or bumpy kinds. Silica is insoluble in water and does not respond...

A brass pole is an alloy pole made up of 2 components: copper and zinc. The copper material is typically more than 60%. According to different copper-zinc proportions, brass rods can be additional identified into different types, such as average brass, aluminum brass, silicon brass, and so on. This alloy...

Luoyang Tongrun Details Modern Technology Co., Ltd will participate in the exhibit( Cubicle Number: E1C01). The product will cover a variety of applications, such as concrete foaming...

Power chips are attached to exterior circuits through packaging, and their efficiency depends upon the support of the packaging. In high-power scenarios, power chips are usually packaged as power components. Chip affiliation describes the electric link on the top surface area of the chip, which is generally aluminum bonding wire...

Betaine surfactants It is produced by the response of fatty tertiary amines and salt chloroacetate, including cocoylpropyl betaine, dodecyl betaine, cetyl betaine, and lauroyl propyl betaine. It is milder than the first 3 and is presently the main surfactant in baby hair shampoo. In 1940, the American DuPont Company invented...

An alloy is made up of copper and various other metal or non-metal components. It has impressive electric conductivity, thermal conductivity, versatility, and deterioration resistance. It is widely used in electrical, construction, transportation, equipment, and other fields. According to various alloying components, copper alloys can be divided into numerous types,...

The main raw materials of lithium batteries include positive electrode materials, negative electrode materials, separators and electrolytes. These raw materials play a vital role in lithium batteries. The cathode material is one of the core components of lithium-ion batteries, mainly composed of lithium cobalt oxide, ternary materials (such as lithium...

With the continuous development of science, technology and productivity, power electronic equipment plays an increasingly important role in our lives and work. Among them, the BTW69 thyristor, a key power electronic device, has a wide range of applications and excellent performance. However, thyristors may still be a relatively unfamiliar concept...

1. Lubrication The hydrophilic group in the superplasticizer has solid polarity, so the adsorption film of the water-reducing representative externally of the concrete particles can form a stable solvated water film with water molecules. This water film has good lubrication effect and can effectively decrease the sliding resistance between concrete bits,...
