At present, there are many kinds of materials used in the control box and control cabinet industry. However, depending on the role of the product, the materials selected are also different. The materials are mainly selected according to the application, cost, adaptability to the environment and durability. .
The main application materials are divided into:
1. Cold-rolled plate SPCC, mainly used for electroplating and baking varnish, low cost, easy to form, material thickness ≤ 3.2mm.
2. Hot rolled sheet SHCC, material T ≥ 3.0mm, also used for electroplating, painted parts, low cost, but difficult to form, mainly using flat pieces.
3. Copper: It mainly uses conductive materials, and its surface treatment is nickel plating, chrome plating, or no treatment, and the cost is high.
4. Stainless steel "target=_blank> stainless steel: mainly used without any surface treatment, high cost. Aluminum plate is generally surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, plating nickel.
5. Aluminium profiles: Parts with complex cross-section structures are used in a variety of plug-in boxes. The surface treatment is the same as the aluminum plate. Galvanized sheet SECC, SGCC. SECC electrolytic board is divided into N material and P material. N material is mainly used for surface treatment, and the cost is high. P material is used for spraying parts.
Each of the five commonly used materials has its own advantages and disadvantages, but why choose most companies to choose stainless steel "target=_blank> stainless steel material, first, stainless steel "target=_blank> stainless steel control box has waterproof, rust-proof and easy to clean, etc. Features, the use of frame, polyurethane foam sealing ring with waterproof design of the door frame, with up to IP54 protection, widely used in the field of automation control equipment. Secondly, it has excellent corrosion resistance, atmospheric corrosion resistance and high temperature strength. It can be used under harsh conditions. It also has strong corrosion resistance and good properties for alkali solutions and most organic and inorganic acids. Corrosion resistance. It can counter most weather conditions in the general natural environment.
Most control boxes work outdoors, and environmental factors have a great impact on service life. Therefore, the stainless steel "target=_blank> stainless steel control box has been favored by many customers for its good corrosion resistance.
Beijing Century Honglian Science & Trade Co., Ltd. is a complete machine supplier, focusing on stainless steel "target=_blank> stainless steel control box, control cabinet. For dozens of high-speed rail, and telecommunications, railway, municipal engineering, smart city, Internet, security, The new energy and other engineering projects are equipped with stainless steel "target=_blank> stainless steel control box. We rely on advanced technology, excellent quality and excellent service to be trusted by customers.

Butterfly valves are commonly used in piping systems to control and regulate flow and speed.
The use of butterfly valve is also relatively simple, easy to operate. And butterfly valve is widely used in all walks of life, is an important control fluid system equipment.
, for air conditioning system: A butterfly valve can control the flow of air conditioning pump and piping system to adjust the temperature of the air conditioning system, so that the air conditioning system can work more efficiently.
2, for water treatment: butterfly valve can be used for water treatment process, can effectively control and adjust the flow of water pipe, carefully adjust the appropriate quality of water.
3, used for power system: butterfly valve can also be used for power system, can effectively control and adjust the flow of water and pressure in the power system, to ensure the normal operation of the power system.
4, used for heating system: butterfly valve can also be used for heating system, can control the flow of hot water piping system and adjust the temperature of the heating system, in order to meet the temperature requirements of the house.
In general, the use of butterfly valves is very wide, from air conditioning systems to water treatment, from power systems to heating systems, a variety of industries can benefit from the use of butterfly valves. Moreover, butterfly valve structure is simple, easy to maintain, for enterprises is also an affordable choice.
