Industrial use of slurry pump gold

The industrial use of gold was formed in the early 1950s with the development of high technology, mainly used in electronic industry, information industry, aviation and aerospace industries. The reason why gold is used in modern industry is that it has many excellent properties, such as chemical stability, corrosion resistance, non oxidation, conductivity and thermal reflection of sunlight.

Application in electronic and information industry. Gold is widely used in equipment and consumables of electronic, electrical and communication industries, such as relays, solid-state circuit micro integrated blocks, connectors, high-frequency switches for telephones, program-controlled exchanges, televisions and wireless communication equipment, etc. the use of pure gold or gold-plated materials can ensure the reliable contact, as well as the repeatedly connected or cut-off conversion performance.

Application in aerospace industry. Gold can make the instructions and signals sent between the electric system installed on the jet aircraft, aerospace vehicle and missile and the ground receiving system transmit to the receiver through the coupling without interruption of one thousandth of a second; after the gold-plated aluminum-plastic heat-insulating reflective screen is installed on the outer shell of the space station, the temperature in the station can be reduced from 43c to 24 "C; a layer of 0.2y thick is plated on the space suit The gold of UM can protect astronauts from infrared radiation when they walk in space.

Application in military industry. Gold can be used to make infrared detectors and Anti Ballistic Missile Equipment for various purposes; gold plating on navigation telescope can make telescope clear for a long time without scrubbing.

Application in chemical industry. In the chemical industry, gold is mainly used as catalyst. The finely prepared gold support catalyst has high activity and selectivity, and its working temperature is lower than any other catalyst. The nanometer gold support catalyst has strong catalytic activity,

It can reduce the reaction temperature of some chemical reactions: the gold salt produced with gold as raw material is the main raw material of electroplating industry: gold is often used as the safety film of chemical equipment.

Application in textile industry. Gold alloy is the first choice material for the spinneret of chemical fiber production equipment; flat gold-plated silk is often used for lace or edging of noble textiles on cotton or silk threads; gold is used as the raw material for gold printing and color coating technology on silk.

Application in ceramic and glass industry. Gold can be used as a colorant in the ceramic and glass industries. Gold, bismuth and rhodium alloy are dissolved in aromatic oil to make "golden water", which is used as dye to draw patterns on the glaze of high-grade porcelain, enamel and craft porcelain. After calcination, the patterns can be made into golden border or golden pattern. Gold chloride is used to decorate the red and purple glaze background color of porcelain. Purple red colloid made of tin chloride solution is added into the dilute solution of weak acid gold chloride, which is the color of red glass Color agent.

Application in architectural decoration. Gold can be used for building decoration to show the luxury of buildings; it is also often used as a protective material for building glass, which can reflect the heat radiation of sunlight.

⑧ application in commodity industry. Gold is a good material for making infrared radiator of heating and drying equipment. It is also often used in the production of daily necessities such as gold pen, watch case, watch belt, glasses frame, etc.

(3) gold is used to make jewelry

Gold has high chemical stability, beautiful color and other excellent characteristics and ornamental collection value, so it is often used to make jewelry, jewelry and various artifacts. At present, a large amount of gold is used to make jewelry in the world every year, accounting for about 80% of the total amount of gold used in the manufacturing industry.

(4) gold for medical treatment

Gold can be used as medicine for curing diseases and longevity, and gold can be used for treating tuberculosis and arthritis. In addition, gold is widely used in dental materials, acupuncture materials and human implant materials. For example, gold can be used for inlaying teeth, making 14K gold needle in acupuncture, as the material of embedded cardiac pacemaker, as the material of vision, hearing, pain and other nerve repair stimulation devices.

What is the main purpose of silver?

In addition to being used as currency, silver is also widely used in modern industry and medical treatment.

(1) silver as currency

Like gold, silver has many excellent physical and chemical properties and natural attributes: silver bright color, with aesthetic value; less output and reserves; solid state, good ductility, easy to form: large density, small volume, easy to carry and store; easy to separate and merge; storage value. Therefore, silver was used as money in ancient times. As gold is precious, gold is the main currency and silver is the secondary currency.

(2) silver is used to make jewelry and other ornaments

Because silver has beautiful color like moonlight, soft texture, good corrosion resistance, good ductility and silver white bright color, it is often used to make various jewelry and silver tableware, such as silver basin, silver bowl, silver spoon, wine cup, necklace, ring, bracelet, etc.

(3) application of silver in medical treatment

In surgery, silver based alloy materials are widely used in dental inlay, repair and material welding. Silver alloy can be used in acupuncture and moxibustion. Silver chloride is the material for making medical optical fiber. In medical diagnosis and detection, silver halide is a good photosensitive material for making photosensitive imaging materials. Therefore, it is widely used in medical diagnostic equipment, such as medical X-ray film, CT film and nuclear magnetic resonance imaging The electrode made of silver can be used to make biosensor for blood detection; in medicine, silver has the function of disinfection and sterilization, and can be used for the preservation of water, wine, vinegar and milk.
