Waterproof box, commonly used waterproof grade editor
General waterproof grade between IP63 and IP68. Divide into
IP63: water or rain has no effect from the 60 degree corner to the case;
IP64: the liquid is poured in any direction to the shell without affecting the damage;
IP65: rinse with water without any damage;
IP66: it can be used in cabin environment;
IP67: resistant immersion in a short period of time (1m);
IP68: for long periods of immersion under certain pressure, such as deepwater cable connections.
Material editor for water proof box
The main waterproof materials are: plastic (ABS/PC), glass fiber, iron, stainless steel and so on
Plastic waterproof box - ABS material:
ABS waterproof box and PC waterproof box
ABS waterproof box and PC waterproof box
Plastic box? Waterproof material for ABS resin (acrylonitrile butadiene styrene copolymer, ABS Acrylonitrile Butadiene Styrene acronym) is a thermoplastic polymer material with high strength, good toughness and easy processing molding. Because of its high strength and corrosion resistance, it is often used in the manufacture of plastic water proof boxes.
The waterproof box made of this material is generally made of industrial grey, opaque, and can be added to the dye as required by the customer. Because of the use of different occasions, but also appeared anti radiation, anti burning and other waterproof boxes.
The waterproof boxes circulating in the market are divided into three grades:
First, international brand waterproof box, because time has proved the quality, but the price is more expensive;
Two, the domestic high-end waterproof box, rookie enterprises to create brand, the selection of materials are imported new materials, while the price is more in line with the domestic market.
Three, the domestic low-end products, applications and waterproof grade and quality without engineering requirements, materials are generally 2 times or 3 times, the advantages of low prices.
Plastic waterproof box - transparent material:
Transparent plastic waterproof box material is mainly PC, polycarbonate (Polycarbonate), abbreviated as PC, is a colorless transparent qualitative thermoplastic material. The name derives from its internal CO3 group.
The main difference between waterproof boxes made of this material and ABS waterproof boxes is transparency, as shown in the figure above.
Metal waterproof box - iron or stainless steel
The waterproof box made of iron or stainless steel is a metal waterproof box. Compared with plastic waterproof box, the explosion-proof performance of metal waterproof box is stronger than that of the plastic waterproof box. But the waterproof box of the same volume compared to the quality of metal waterproof box is more obvious than the plastic waterproof box, the insulation is poor, while the height is more than 1M, the cost is relatively high, so is mainly used for large power distribution cabinet, switch box etc..
Glass fiber waterproof box - glass fiber
Glass fiber waterproof box, as its name implies, is made of glass fiber, and can be substituted and superior to iron waterproof box in its function. Glass fiber is superior to organic fiber in temperature resistance, non burning, corrosion resistance, heat insulation, sound insulation (especially glass cotton), high tensile strength, good electrical insulation (such as alkali glass fiber). But it is brittle and has poor wear resistance. Glass fibers are mainly used as electrical insulating materials, industrial filtering materials, corrosion protection, moisture proof, heat insulation, sound insulation and shock absorption materials. Can also be used as reinforcing material.
Main use of waterproof box editor
Waterproof box because of the geographical differences and the scope for different names are not the same for the industry are the main waterproof junction box, instrument box, waterproof waterproof PV junction box, waterproof box is mainly suitable for indoor and outdoor electrical, communications, fire fighting facilities, iron and steel smelting, petrochemical, electronics, electric power, railway, construction sites, mines mining field, airports, hotels, ships, large factories, coastal factories, dock equipment, waste water treatment facilities. Environmental pollution, facilities, etc.
Waterproof box development trend editor
The development of waterproof box with city power and communications construction requirements of wire and cable, communication cable and signal cable buried the requirements of cable branch connection, such as providing waterproof solution is a very important proposal. Plastic waterproof box has been successfully used abroad for more than 20 years, and it is also widely used in our country. Before 2000, China's use of multi metal waterproof box made of iron; after 2000, the rapid development of China's science and technology, plastic technology gradually improved, the plastic waterproof box with its low cost, good insulation, waterproof high degree gradually replaced the metal waterproof box.
