In the PET bottle blowing process, the choice of e short wave ir emitters needs to be integrated with a variety of factors to consider, the following are some suggestions:1, wavelength\\uff0cShort-wave halogen heating lampStrong penetrability: PET materials have good absorption of short-wave infrared (wavelength range of about 1 – 3 microns). Short-wave infrared heating lamp emit short-wave infrared rays that can penetrate the surface of PET preforms, penetrate deep into the material, so that the preforms inside and outside of the same time, uniform heat. This penetration helps to quickly raise the overall temperature of the preform, improve heating efficiency and reduce heating time. Fast heating speed: Because its energy can be effectively absorbed by PET and good penetration, short-wave halogen lamp infrared can make PET preforms warm up quickly, which is very critical to improve the production efficiency of bottle blowing machine. For example, in the high-speed blowing production line, short-wave Halogen heating lamps can meet the demand for rapid heating, so that the bottle blanks in a relatively short period of time to reach the appropriate temperature required for blowing. 2, heating uniformity\\uff0cHeating tube with reflectorEnhance uniformity:halogen heating bulb with reflector can reflect and focus infrared rays, adjust the direction of infrared radiation, so that all parts of the bottle blank can receive uniform infrared radiation. For PET bottle blowing, the uniform heating can avoid localised overheating or overcooling of the preform, thus preventing uneven wall thickness, deformation and other quality problems of the blown bottles.Customised reflector: According to the specific structure of the blowing machine and the shape and size of the preform, the shape and angle of the reflector can be customised to achieve the best heating uniformity effect. For example, for different shapes (round, square, etc.) of preforms, the reflector can be designed with different curvatures to ensure that the infrared rays cover the surface of preforms evenly.3\\u3001Power\\uff0cDetermined according to the size of the preforms and production speedLarge preforms or high speed production: If you want to blow large PET preforms or production speed is faster, you need to choose a larger power replacement infrared halogen lamp. Large preforms require more heat to reach the blowing temperature, while high production speeds require sufficient heat in a shorter period of time. For example, for a PET bottle blowing process with a large volume (e.g. 5 litres), a more powerful heater is required to ensure that the preforms are heated up quickly to the right blowing temperature range (approx. 100 – 120\\u00b0C).Small preforms or low production speeds: For small preform sizes and slow production speeds, the power can be relatively low to avoid overheating and wasted energy. For example, for the production of small PET bottles (e.g. up to 300 ml), a heater with a low power can meet the heating requirements. 4\\u3001Quality and stability\\uff0cWell-known brand and high-quality materialsBrand reputation: choosing halogen infrared heat lamp of famous brands can ensure the quality and stability of the products. henruite is a brand that usually has strict production standards and quality control system, and its products have been rigorously tested and verified to be able to work stably for a long period of time in the PET blowing process.High-quality materials: the tube material of the heating tube (such as quartz glass or ceramics, etc.) should have good high-temperature resistance, high infrared transmittance and good chemical stability. The heating wire material (such as nickel-chrome wire or carbon fibre, etc.) should have stable heating performance, good oxidation resistance and other characteristics to ensure the service life and heating effect of the heating pipe.
