What is straight iron, first of all, explain to everybody, straight hair, also known as plywood, is a kind of electronic products for the hair straightening, the technology originated in 1995, using the electromagnetic principle makes an object (namely the heating element, said heating element below) to generate heat, by means of temperature transmitted to a layout, use of high temperature and the straight hair, average temperature around 200 degrees. International beauty authorities specify the best modeling temperature of 220 degrees, but in our China, the average temperature is between 160 and 200 degrees. And the hair straightener develops to have already had earthshaking change today, not only can straight hair, still have the function of curl and clip out wave hair. It also emits ozone and negative ions. Since 2007, I have entered the family personal market, and I can give my hair a SPA at home. In the 21st century, straighteners will enter China's home market and become a must-have product for personal care, like hairbrushes.
1) according to the difference of heating body, the straightener can be divided into ceramic heating body,PTC heating body and MCH heating body.
Ceramic heating element has the advantage of environmental protection, heating speed, generally 30 seconds to 45 seconds to make plywood surface temperature of 200 degrees. But due to the ceramic heating element was sintered under the high temperature above 1000 degrees, the temperature after the loss of control circuit, quickly more than 300 degrees, it will burn out fixed heating plate of plastic material, make the heating plate, is likely to come into contact with the user, and burn the skin.
PTC stands for Positive Temperature Coefficient. PTC is sintered at high temperature, but he is the highest temperature surface can be controlled during sintering, according to the requirements of the manufacturer can be put to 280 on the surface, or manufacturer of any temperature, general is sintered to 230 degrees to 280 degrees. But its shortcoming is the slower pace in the heat to 200 degrees, usually in a minute and a half or 2 minutes. The other in use, can't keep like ceramic heating element at a high temperature. The effect of straight hair slightly less.
2) according to different materials of heating plate, the straightener can be divided into: pure ceramic heating plate, aluminum plate with ceramic glaze sprayed on the surface, and glass plate with microcrystal
Ceramic heating plate has the advantage of environmental protection, insulation performance is good, good security, the disadvantage is that the processing cycle is long, the processing link, and because the edge of very smooth, in the process of straightening the hair will be slightly pulling my hair.
Spray aluminum ceramic glaze has the advantage of easy production, in addition due to mechanical forming, the edge is very smooth, not pulling hair. Because the surface is basin of ceramic glaze, pull hair effect is very good also. The disadvantage is that because it is metal, itself is not insulation, insulation to the internal heating element, and to avoid the leakage cause potential safety hazard.
Microcrystalline glass plate is seldom used, mainly because its surface is not as smooth as ceramic glaze. In addition, it is not easy to be formed and fixed.
3) straight iron to distinguish from the structure, general component is V and X type two kinds, early popular X, but V more popular this year. Because V not only can straighten hair, straight and streamlined appearance, can also be used to curl, more and more stylist in straightening curly hair.
4) according to different power sources, the straightener is divided into wired straightener and wireless charging type straightener
Cable straight iron -- straight iron work by connecting the mains power supply, the straight iron with wireless charging is made by a charger was carried out on the rechargeable battery, the use of battery as a power supply.
Cable straight hair apparatus has the advantage of continuous work, the disadvantage is that if the straight iron production control unreasonable design, there will be potential safety problems, in addition there is a power cord will not convenient in use, the other is to carry out inconvenient. The benefits of wireless straight iron is safe, because is a tributary of the power supply, another is travel easy to carry. But the disadvantage of wireless straight iron per charge is only 30 minutes to 1 hour after.
5) the straightener can be divided into wide plate, middle plate, narrow plate and mini type according to size
Wide plate straightening hair plate length is 90 mm, generally width is 42 mm, straight and medium plate plate length is 90 mm, generally 24 mm, width is the length of the straight and narrow plate plate usually is 80-90 mm, width is 13-14 mm, miniature general is 60 mm the length of the straight plate, width is 13-14 mm.
6) according to the type of hair pulling, the straightener can be divided into common type and dry and wet type. The normal straightener must blow dry the hair before it can start pulling. The dry and wet type can pull the hair wet. The dry and wet hair straightener should have 8-10 air holes in its hair straightener, so that water can be changed into steam to come out of the air hole.
7) voltage and export countries are classified. The plugs include Chinese plugs, European plugs, American plugs (American leakage protection plugs), Australian plugs, Japanese plugs, German electric plugs, South African plugs and British plugs. Voltage has: 110V - 240V universal voltage also has, only for a certain country, specific voltage or current.
