The difference between halogen infrared heating lamp with coating and without coatingIn terms of heating efficiencyCoated heating tubes: Coating can change the radiation characteristics of the industrial infrared heat lamp. Some special coatings can enhance the infrared emissivity, making the infrared energy emitted by the heating tube more concentrated and more intense. For example, the Infrared Halogen Heater Parts coated with infrared selective coating emits infrared wavelengths that are more in line with the optimal wavelength range absorbed by the heated object, allowing the heated object to absorb infrared energy faster, thereby achieving more efficient heating. This type of halogen heat lamp has obvious advantages in application scenarios that require rapid heating, such as the plastic thermoforming process on industrial production lines, which can enable plastic materials to reach the softening temperature faster and improve production efficiency.Uncoated Halogen IR Lamps: The radiation characteristics of uncoated heating tubes are relatively ordinary. The infrared energy distribution it emits is relatively wide, and when heating certain objects that have specific requirements for infrared absorption, it may not be able to efficiently transfer energy to the heated object. For example, in some high-precision heating processes that require high heating speeds, such as welding preheating of electronic components, uncoated Infrared Heating Lamps may cause prolonged heating time due to low energy transfer efficiency.Service lifeCoated heating tube: Suitable coating can protect the Quartz Infrared Halogen Heating Element. For example, some corrosion-resistant coatings can prevent the heating tube from being corroded by factors such as moisture and corrosive gases in the environment. In humid or chemically corrosive environments, such as food drying workshops or chemical raw material heating processes, coating can greatly extend the service life of the Infrared Quartz Heating Element. At the same time, the coating can also reduce the oxidation rate of the heating tube at high temperatures, maintain the performance of the heating tube stable, and reduce the performance degradation and damage caused by oxidation.Uncoated heating tube: Without a protective layer, the heating tube is easily affected by external factors. In an environment with high temperature, high humidity or corrosive substances, the filament of the heating tube may oxidize faster, resulting in a decrease in its performance. Moreover, without the protection of the coating, the mechanical strength of the heating tube may also be affected, such as being more susceptible to damage when slightly hit or vibrated, thereby shortening the service life.Heating uniformityCoated short wave quartz glass heating lamp: Certain coatings can improve the radiation uniformity of the heating tube. Through a special coating process, the infrared rays emitted by the Quartz Infrared Heating Element are more evenly distributed within a certain range, so that the heat received by each part of the heated object is more uniform. In application scenarios that require uniform heating, such as drying of printed materials or hot bending of glass, this uniform heating feature can ensure product quality. For example, in the process of drying printed materials, uniform heating can prevent uneven drying of ink due to local overheating, thereby ensuring the quality of printed materials.Uncoated Shortwave IR Heat Lamps Its radiation uniformity mainly depends on the structure and manufacturing process of the Halogen Infrared Heating Lamp itself. Relatively speaking, when there is no coating to assist in optimizing radiation uniformity, in some application scenarios with high requirements for heating uniformity, a more complex heating tube layout or additional auxiliary equipment may be required to ensure uniform heating of the heated object.Scope of applicationCoated Shortwave Infrared Heating Quartz Lamp: Due to the various advantages brought by the coating, such as efficient heating, good corrosion resistance and uniform heating, it is suitable for more complex and special heating needs. For example, in the disinfection process of medical equipment, precise temperature control and good corrosion resistance are required, and coated Infrared Quartz Heating Lamp can meet these requirements; in the heating link of precision electronic manufacturing, it can also provide efficient and uniform heating.Uncoated heating tube: Uncoated infrared quartz heating tube is suitable for some simple application scenarios with relatively less stringent heating requirements. For example, in some common indoor heating equipment, as long as the basic heating needs can be met, short wave infrared heater lamp without coating can also be used normally, and the cost may be relatively low.
