Separation and enrichment of gold and silver

The content of gold and silver in materials is usually low, and separation and enrichment are required before determination. Even for pure gold, pure silver, or gold and silver alloys, when it is necessary to determine the impurities, separation is also required to eliminate the interference of a large amount of gold and silver matrix. Therefore, the purpose of separation and enrichment is mainly to: (1) improve the sensitivity of the determination; (2) eliminate the influence of a large number of coexisting elements.

How to implement design and protection measures for directly buried insulated pipes

Direct-buried insulation pipes are used in liquid and gas transmission networks, chemical pipeline insulation projects, petroleum, chemical industry, central heating networks, central air conditioning ventilation pipes, municipal engineering, etc. Direct-buried insulation pipes are a type of prefabricated insulation pipe with good insulation performance and low engineering cost. 1. Based on actual cases, the corrosion protection grade of direct-buried insulation pipes should be determined according to the local soil corrosion grade. When the soil corrosion grade is high, the corrosion protection grade should consider extra strengthening grade; when the soil corrosion grade is medium, the corrosion protection grade should consider strengthening grade; when the soil corrosion grade is low, the corrosion protection grade should consider ordinary grade. Therefore, the soil corrosion grade of the pipeline laying section must be clarified during design to optimize the corrosion protection grade.

Three correct ways to use a 10-ton electronic crane scale

A 10-ton electronic crane scale requires the use of an electric hoist and is generally used in steel plants, rolling mills, steel mills, slitting and leveling plants, bridge factories, heavy machinery plants, docks, etc. The correct usage of a 10-ton electronic crane scale is as follows: 1. When installing or replacing the battery of a 10-ton electronic crane scale, tighten the battery clip locking screw, check if the battery clip is firmly fixed to the scale body, then close and lock the crane scale door to prevent accidents. When the instrument displays low voltage, replace the battery pack immediately and charge the replaced battery in time to prevent battery damage. When the battery pack is not used for a long time, it should be charged at intervals. The battery should be stored

A brief explanation of the daily maintenance knowledge of high and low temperature test chambers

1. We generally recommend placing the high and low temperature test chamber in an environment with a temperature of 8℃~28℃. For laboratories that do not have this condition, appropriate air conditioners must be provided. 2. Adhere to dedicated personnel management and maintenance. Units with the resources should regularly send dedicated personnel to the supplier's factory for training to gain better maintenance and repair experience and capabilities. 3. Regularly clean the condenser every 3 months. For those using air-cooled compressors, regularly inspect the condenser fan and clean the condenser to ensure good ventilation and heat exchange performance. For those using water-cooled compressors, in addition to ensuring the water inlet pressure and temperature, the flow rate must also be ensured, and the condenser should be regularly cleaned and descaled to maintain its continuous heat exchange performance.
