Not long ago, "there was a flight attendant who answered the phone while the phone was charging, causing the electric shock to die." Recently, mobile phone bombings have occurred in Hunan and Yunnan, blowing clothes and spontaneous combustion. Experts say this is likely to be related to cell phone batteries or chargers. China Battery Network reminds everyone that if you find that your phone is too hot, you must stop it as soon as possible! Because all mobile phones have an overheating phenomenon before they explode. Please remember the following four precautions and tell each other! 1. Do not operate the charger when the hand is wet 2. The battery avoids charging for a long time 3. Don't put the charged phone in the bed or near the person 4. Use the mobile phone as carefully as possible to avoid strong direct collision and avoid prolonged exposure to high temperature environments, such as exposure, fire, and water. If you find that your phone is hot, you must stop it as soon as possible. 5. Finally, remind everyone that the phone should not be placed in the chest pocket, and it is best not to put it in the trouser pocket. If you are at home and in the office, the phone can be taken out on the table.
The main advantage of the epc
1. The shape of casting size precision, good repeatability, has the characteristics of precision casting;
2. The casting surface finish high;
3. Cancel the sand core and core xiaohong, eliminated due to core, the core of casting defects and waste;
4. Out of box, not modulus, greatly simplifying the molding process, to eliminate the casting defects caused by modulus, tanks and waste;
5. The binder, water, dry sand molding without any additives, eliminated due to moisture, additives and binder caused by all kinds of casting defects and waste;
6. Greatly simplifies the sand processing system, the sand can be repeated use, all cancelled &industry sand preparation and waste sand treating section;
7. Shakeout extremely easy, greatly reduces the shakeout workload and labor intensity;
8. Castings without flash burr, make clear the burnish workload by more than 50%;
9. Can be set up in an ideal position reasonable shape of the riser, is not subject to classification, the restriction of traditional factors such as modulus, reduce the internal defects of casting;
10. Negative pressure casting, is more advantageous to the liquid metal filling and feeding, improved the casting organization density;
11. A combination of pouring, a box, greatly improving the casting craft production rate and production efficiency;
12. Reduce the machining allowance, reduces the machining cost;
13. Automatic assembly line production, easy to realize mechanization production line elasticity, can implement different alloy on a production line, different shape, different size of casting production.
14. You can cancel the draft Angle;
15. The use of metal die life can reach more than 100000 times, reduce the mold maintenance;
16. Reduced the dust, smoke, and noise pollution, greatly improved the working environment of foundry workers, reduce the pain
Dynamic strength, mainly men can become predominantly female industry;
17. Simplified the process operation, on the degree of skilled workers required is greatly reduced;
18. The shape of the parts is not restricted by the traditional casting process, the liberation of the mechanical design workers, to make it according to the using performance of the parts, free to design the ideal shape casting;
19. Can reduce the casting weight;
Reducing the production cost; 20.
21. Simplified the factory design, can reduce 30 ∽ 40% of investment in fixed assets, covers an area of area and construction area
30 ∽ 50%, reduce power consumption can reduce 20%; 10 ∽
22. The epc technology widely used, not only suitable for cast steel, cast iron, more suitable for cast copper, cast aluminum, etc.;
23. The Epc Casting process is not only suitable for simple geometry, more suitable for ordinary casting to attack rolled edge, core, geometric shape of complex castings;
24. The Lost Foam Casting process can realize microtremor state pouring, promote the formation of the special requirements of metallographic organization, to improve the inner quality of casting;
25. Combined on the dry sand casting, easy to take off the sand, temperature, therefore can make use of waste heat to heat
Richard.Especially high manganese steel castings water edge processing and heat resistant steel solid solution treatment, the effect is very ideal, can save a lot of energy, shorten the processing cycle;
26. The use of epc process, can according to melting ability, complete any size castings.
