chi hair straightene 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, it 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 ghd iv 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 hair hair straightener ceramic heating plate temperature adjustment has the advantage of environmental protection, and good insulation, safety and the good, the disadvantage is that the processing cycle length, processing, and because the edge of a very slippery in straightening the hair will be slightly plucked hair. Aluminum plate spray ceramic glaze of benefits is easy to produce, as a result of machining, edge was slippery, will 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 the degree of surface slip glaze is better than good, and not easily fixed, forming products structure redesign. 3) hair from the structure, 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, more and more hair stylist to Yung curls. 4) in accordance with the power of different hair ghd straighteners, hair is divided into the wired and wireless Cordless hair straightener hair 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, is away carrying inconvenient.
