Hair straightener or electric splint, colloquially called a splint, through the current heating heating of chi hair straightener or PTC or heating, transmitted to the aluminum sheet or ceramic plate heating. Hair straightener, Gu Holmes is the hair straightening, hair by heating elements heat, soften, then cooling to achieve straight hair. Now the hair, the straightening and La volume. Previous hair straightener, major users is a professional hairdresser salon, Europe and America from 2007 has entered the domestic market, the individual at home can give hair a SPA. 2010 hair straightener will enter the Chinese market, the family will become a must-have products for personal care, like a toothbrush as popular. [Edit this] hair category 1) hair is different according to the heating element can be divided into PTC ceramic heater, heater and high fever. injection hair straightener ceramic heating element has the advantage that, environmental protection, temperature rises rapidly, generally 30 to 45 seconds can make the splint surface temperature reached 200 degrees but because gepu is 1000 degrees centigrade under high temperature sintering, lost control of the temperature in the circuit, ghd iv styler can quickly exceed 300 ° c, will burn out the fixed heating plate plastic materials, heating plate falls off, there may be exposed to users, and burns on the skin. PTC is an abbreviation for Positive Temperature Coefficient, translated is positive temperature coefficient, hereinafter referred to as PTC Thermistors. PTC is sintered at high temperatures, but the maximum surface temperature can be controlled when the sintering, according to the manufacturer’s request, you can put the surface to 280, or manufacturers want any temperature sintering, generally to 230 ° c to 280 ° c, but the disadvantage is warming up to 200 ° c at relatively slow speeds, normally a ½ or 2 minutes. Furthermore in use, cannot like gepu that continuously at high temperature. The effect of the straightening hair slightly less. 2) hair according to different heating plate material, can be divided into: pure ceramic heating plate, the surface of the ceramic glaze of aluminum plate, glass ceramic heating plate temperature control hair straightener has the advantage of better environmental performance, insulation, security is good, the disadvantage is that processing cycle length, processing, and because the edge of a very smooth, straighten hair are slightly plucked hair. Aluminum plate spray ceramic glaze of benefits is easy to produce, as a result of machining, very smooth edges, do not pull the hair surface is the basin-ceramic glaze, Bratislava effect is also very good. shortcomings due to the metal, insulation, does not in itself to carry out the internal body heat insulation in order to avoid leakage of a security risk. Application less glass, mainly its surface smoothness as well as ceramic glaze, not easily fixed, forming products structure redesign. 3) hair from structural distinction generally consists of v-type and x-type, two of the more popular, early X-type, but this year v-more popular because v-not only can straighten hair, hair straightener, streamlined appearance can also be used for curly hair irons, ghd straighteners an increasing number of stylist to Yung hair curls. 4) in accordance with the power of different hair straightener, hair is divided into the wired and wireless Cordless hair straightener hair turn tail cable connect mains hair through supply of hair straightener, wireless Cordless hair straightener is a charger for rechargeable batteries, battery as power supply. Wired straight hair is continuous, the disadvantage is that if hair design production control unreasonable, there will be a security risk, and use a power cord may not be convenient, the other is to carry out.
