Introduction and Advantages of Explosion-proof Mobile Phones
What is explosion-proof mobile phone?
Explosion-proof mobile phone, as the name suggests, is a phone that can resist explosions. However, its explosion-proof meaning is not to prevent explosions from happening, but to refer to a flameproof mobile phone that will not cause explosions in flammable and explosive environments.
Explosion-proof mobile phones have many types of explosion-proof features. The most common one is intrinsic safety explosion-proof. For a mobile phone, the following factors may cause an effective ignition source: circuit short circuit or electric spark, internal or external short circuit of the battery, mechanical damage caused by falling or heavy impact, failure of any possible semiconductor components, high temperature, and static electricity.
Intrinsic safety explosion-proof mobile phones increase protection circuit, increase circuit board line spacing, shield and package electronic components, use special materials to make phone cases, and other measures to ensure that the energy generated by the electronic components inside the phone is not sufficient to form an effective ignition source even when short circuiting and failing, thus ensuring the safety of users in flammable and explosive environments. Explosion-proof mobile phones have been applied to petroleum companies, gas industry, coal gas, the natural gas industry, chemical industry, and pharmaceutical industry, underground mine phones for mine industry.
The advantages of explosion-proof mobile phones
The advantage of explosion-proof mobile phones is that they are usually not easy to become ignition sources. The reason why ordinary phones are prone to be ignition sources is mainly caused by the electric spark emitted by the battery, or the structural damage caused by short circuit or falling of the phone, high temperature, static electricity and other issues, all of which can be effectively avoided in explosion-proof mobile phones.
Explosion proof walkie talkie and explosion proof intercom system are usually modified from ordinary mobile phones. They avoid the components such as batteries, flashlights, and capacitors that are prone to heating or even explosions when they fail, and prevent them from igniting flammable gases or dust in flammable and explosive places. Explosion-proof mobile phones must be certified by an explosion-proof mechanism and awarded an explosion-proof certificate before they can be used in flammable and explosive areas, usually with EX or MA marks.
In terms of waterproof, dustproof, and shockproof technology, the grade of explosion-proof mobile phones will also be higher than that of ordinary mobile phones. Moreover, they have passed various tests in testing agencies and obtained explosion-proof certificates. With these certificates, workers in explosion-proof areas can also use them with peace of mind.
Overall, explosion-proof mobile phones are indeed more secure than ordinary mobile phones, especially for some special professions. However, for people who do not work in these high-risk scenarios, ordinary mobile phones are equally suitable for daily needs.
