Now, with the growing role of smartphones in our lives, you will find that smartphones are very good at all aspects of their lives. With the increasing number of mobile applications, mobile phones are important to people. Performance is getting stronger and stronger, so everyone's awareness of mobile phone protection is also increasing. With the continuous development of mobile phones, you can find that the waterproof and dustproof function has become a must-have function of mobile phones, and now many mobile phone manufacturers will be able to achieve the best waterproof and dustproof effect when releasing mobile phones, then Are the protection features of these phones really useful? Let's first look at how the phone is waterproof. You can see that there are a lot of opening designs on the phone now, so there will be gaps in the hole to allow particles or water to enter, so how is the phone in this? What about protective measures in case? First of all, the mobile phone should be waterproof. The most important thing is to waterproof the mobile phone motherboard. If the core components of the mobile phone are not waterproof, the possibility of short circuit or damaged components of the mobile phone will increase greatly, and the waterproof of the mobile phone cannot be discussed. In fact, the waterproof mobile phone is sealed on the internal important components such as the mobile phone motherboard. This technology is realized by a professional vacuum nano-waterproof coating process, which can be coated with a vacuum nano-protective film on the mobile phone component. It is very good to protect the internal components of the mobile phone from the intrusion of other substances, thus achieving waterproof function. For the design of the opening of the handset and the earphone hole, the manufacturer will put the waterproof plug in the position of the charging socket of the mobile phone and the earphone port. The waterproof plug is generally composed of a waterproof material of silica gel or soft film texture, and This waterproof plug has good resistance to pressure. The stronger the pressure resistance of this tool, the higher the waterproof level, and the better the effect of the phone on waterproofing. That is to say, this design allows the outer opening of the entire mobile phone to be completely closed, thereby realizing the waterproof function of the mobile phone. Based on the above waterproof function, the mobile phone has a good expressive effect in preventing the splashing effect. Now many domestic mobile phones can basically meet the demand in this aspect, but now there is a more powerful waterproof function on the market, which can carry out the whole body. Water washing and underwater soaking, etc., this waterproof function is different from ordinary mobile phones, and it is generally required to reach the waterproof standard of the industry. I don't know if you have noticed. Recently, some flagship machines will be marked with their own waterproof technology such as IP68, which has super waterproof effect. The industry is better at conquering mobile phone waterproofing. Conquering S series mobile phones will apply the latest waterproof level technology to waterproof mobile phones. It is reported that the conquest CONQUEST S12 series mobile phone released last year is equipped with IP68 waterproof function. From the poster information of the promotion, this mobile phone has a very strong level in waterproof and dustproof. Then there are many people who will ask, what does this IP68 mean? In fact, this IP68 represents a mobile phone waterproof level, the higher the level, the better the waterproof effect of the mobile phone, and the IP rating is the standard for preventing the entry of foreign objects by the electronic products established by the IEC International Electrotechnical Commission, and the two numbers behind the letters. They represent the level of dust and water resistance. First, the first number represents the level of equipment to prevent the entry of solid matter, which is what people often say is dustproof. The second number represents the level of equipment to prevent the invasion of liquid substances. It is waterproof. Then we start with dust prevention. At present, the dustproof level is divided into 6 levels, and the 0 level is the unprotected level. The standard indicates that the level 1 can be protected as long as the object with a diameter larger than 50mm. Basically, if the mobile phone is this level. The protection can be discarded. Level 2 can protect 12.5mm objects. Like many appliances, IP2x protection is used. Generally, more sophisticated electronic devices such as mobile phones will use IP5x and above. The equipment under the grade can prevent the foreign matter such as dust from entering, and has good effect on the dustproof of the mobile phone. When the dust level is up to 6 levels, the equipment can completely prevent the entry of foreign objects, which is also the best at present. Dustproof effect Let's talk about the waterproof level. The same level 0 means no protection, level 1 prevents vertical water droplets from entering the device, level 2 prevents water droplets from invading when the device is slightly tilted, and level 3 prevents water from being sprayed at a tilt angle. It can be said that it is rainproof, and the mobile phone must be level 5 or above to be truly waterproof, because 5-6 can prevent large water pressure from invading, and the 7th level is even more powerful. It can be kept under 1 meter. No water in 30 minutes or so, the general mobile phone can carry out 7-level waterproofing, the basic waterproof effect is already very good, but now the market can see that it has reached 8 levels of waterproof, and this level can make the mobile phone and other equipment soak in the water for a long time. It’s okay, netizens joked that this level of mobile phone is in the toilet, and there is plenty of time to consider whether to pick it up.
