Powder Coating Drying “Activator”- High Efficient Heating IR Lamp-Tungsten Quartz Infrared Heaters

Powder Coating Drying “Activator”- High Efficient Heating IR Lamp-Tungsten Quartz Infrared Heaters

In order to have a film with good performance including thinner coating and beautiful surface, high efficient infrared heating technology are more and more used for drying coating with advantages of fast productivity and energy saving. Quartz infrared heaters has the advantages of high radiation energy, high power intensity, matched absorb wavelength, instantaneous start, and stable infrared radiation heating, which can shorten the coating curing time and have a “catalysis” on the good performance of the coating during curing process.   Using high efficient tungsten infrared quartz heaters for furnace heating and curing can be completed in only 60～90 seconds, while the use of a far infrared furnace for curing takes 15 minutes or more time to complete. The efficiency is increased by more than ten times, and the furnace area is reduced by 70%. The compared energy saving exceeds 50%, which is very efficient curing heaters.   Tungsten quartz infrared heaters adopt infrared electromagnetic wave heating, and there is no intermediate medium to transfer heat. When the radiation spectrum of the heating element (tungsten) matches the absorption spectrum of the heated object (workpiece), the thermal efficiency is the highest, thus achieving energy conservation. The difference between tungsten-infrared heaters and far-infrared elements lies in the response time (from power on to constant temperature) of the heating components: tungsten-infrared heater is 1-2 seconds. Far infrared element is 5-15 minutes; Especially the surface power density of tungsten infrared heaters can reach up to 300KW/m2, but far infrared elements can reach only 60KW/m2.   The advantages of tungsten quartz infrared heaters in coating curing process.   Faster Curing 1) High efficient infrared heating uses radiation to heat the workpiece, which takes only 60～90 seconds to complete curing process; Far infrared heating, on the other hand, involves convective heat transfer, utilizing the heat of the air to conduct and heat the workpiece, which typically takes 15 minutes or longer curing time with lower efficiency.   2）Energy saving Theoretically, the curing of the paint film is the product of temperature and time within a certain range. Increasing the temperature can shorten the curing time. Tungsten infrared elements have a very high heating temperature range of 2200～2500℃ （2473K-2773K）.More than 80% of the effective radiant energy can be radiated within 1 - 2 seconds after power on, while the far infrared heater takes 5 - 15 minutes to achieve a similar effect. Quartz infrared tungsten heater lamps can be switched on and off quickly, but the far infrared heating needs to be preheated more than half an hour in advance, and sometimes needs to be cooled after the end of production, so the energy consumption utilization efficiency is lower than sealing quartz infrared heaters.   3）Uniform curing High-infrared heating is faster, and the coating surface receives the same amount of high-infrared radiation energy, resulting in uniform curing; while the temperature difference between the upper and lower parts of the far-infrared heating furnace is large, resulting in uneven curing of the workpiece.

Water Drying By High Efficiency Infrared Radiant Heat Lamps

Water Drying By High Efficiency Infrared Radiant Heat Lamps

Traditionally, water drying processes usually use combustion fuels or electricity for heating, and the external objects are heated to generate heat and transfer it to the material through convection of hot air or thermal conduction, so that the water in the material can absorb heat to achieve the purpose of drying. However, traditional combustion fuels, such as natural gas, liquefied gas, coal, wood, etc., are non-renewable resources, and the combustion process emits a lot of pollutants; the heat loss is large, the energy use efficiency is low, and the drying time is long. Therefore, the use of infrared radiation heating to dry water has become a new way of industrial cleaning and efficient heating.Traditionally, water drying processes usually use combustion fuels or electricity for heating, and the external objects are heated to generate heat and transfer it to the material through convection of hot air or thermal conduction, so that the water in the material can absorb heat to achieve the purpose of drying.

Steel Paint Drying By Infrared Heating Lamp

Steel Paint Drying By Infrared Heating Lamp

Infrared heating technology is to use the principle of electromagnetic radiation heat transfer, the infrared radiation does not need to contact heated objects and does not require intermediate medium to transfer heat, direct heat transfer to heated objects. And our quartz infrared heating has high energy density, strong penetration, fast response, and good temperature controllability. Therefore, quartz infrared heating technology is widely used in printing, textile, semiconductor, glass, electronics and other industrial drying.     Especially in the paint coating drying, infrared rays have strong penetration, they can be absorbed by the particles and coating substrates inside the coating at the same time, from inside to outside or simultaneously heating the coating. Avoiding coating bubbles, shells or wrinkles phenomenon with a faster and higher quality drying coatings. Infrared heating can be placed horizontally or vertically around the coating, take up less space, save equipment costs.     Let us start from the following paint drying requests for steel by infrared quartz lamps. Dear Sir, we are looking at Electric- Infrared Tubes (Explosion-Proof Type) 3.0m length x 0.4m width x 0.2m height for direct heating of painted steel plates from 26C to 80C inside a heating cabinet while the steel plates are moving at the speed of 1.5 ~ 2.5m/min. Power is 415V/3Ph/50Hz. The Paint Drying Cabinet Size: 3.2m Width x 9m Length x 1m Height with airflow of 290cu.m/min generated by centrifugal fan. Can you recommend the number of Infrared Tubes required to achieved 80C inside the cabinet based on the specified air-flow (exhausted out).       1: What is the heated object for the above request? The painted steel plate.   2: What type of quartz infrared heating is good for the painted steel plate? Steel materials absorb 0.76-2um infrared radiation better, so shortwave quartz infrared heating or Fast response mediumwave infrared heating are reasonable for meeting drying purpose.   3: How to distribute quart infrared heating for the steel coating drying? The quartz lamps of infrared heating system are distributed along the running steel plate, installed on the upper and lower sides of the steel plate, or the left and right sides. The lamps of infrared heating system need to be divided into different heating groups and each heating group can be switched on and off and temperature controlled separately to meet the heating needs of different width steel plate.   4: What factors should be considered when designing lamp power? Heating temperature, this is an important factor to design the heating power, and all quartz heating lamps should be controlled by PLC or SCR to adjust the heating temperature in the drying oven. Coating thickness and plate thickness, more thicker plate needs more heating power and we should calculate the biggest thickness plate as an important factor. Plate width, this will be an important factor to design the heating length of each quartz infrared lamp and width of heating lamps group. Plate speed, this is an important design factor, we have to calculate the heating time from entrance to exit and meanwhile the heating temperature can be raised up in the heating time. Plate color, different colors have different efficiency of infrared absorption. The darker the color, the higher the infrared absorption efficiency; the lighter the color, the lower the infrared absorption efficiency. Therefore, the color changes of the steel plate need to be considered in designing of lamp power. air intake or exhaust flow, air into or out of drying oven will have a certain impact on the heating temperature, in order to make steel plate heating temperature more uniform, we need to consider this factor. Other environmental factors, seasonal temperature changes, the heat preservation effect of drying oven.

The gold reflector difference between quartz infrared heater lamps

The gold reflector difference between quartz infrared heater lamps

In order to better convey and focus on the heated material all the IR radiation emitted from quartz heater lamp, the special gold reflector or white reflector will be coated and fixed directly on the quartz surface. The use of a coating reflectors on IR heaters will obtain an additional increase of the IR radiation energy to the heated materials. So the heating efficiency and drying process time will be faster than quartz infrared heater lamp without any reflect layers.   Let us see the following video to feel the heating temperature on reflect layer side and without gold layer side.     We can obviously feel the heat in the direction of the infrared heating, but the heat is very low in the direction of gold coating. This is because the gold coating reflects more infrared radiation back to the direction of heating. We can also confirm the above views through test temperature data and temperature rising trends.   380V 7500W 2500mm Medium Wave Twin Tube Quartz IR Lamp Without Reflector Heating time 0s 10s 20s 30s 40s 50s 60s 90s 2mins 2m 30s Surface temperature 9℃ 35℃ 68℃ 120℃ 180℃ 230℃ 280℃ 400℃ 477℃ 520℃ Heating time 3m 3m 30s 4min 4m 30s 5min 5m 30s 6min       Surface temperature 544℃ 558℃ 567℃ 575℃ 580℃ 582℃ 585℃

Let us take clear quartz infrared heater of 7500W 2500mm toatl length with 2300mm heated length as example.                                                                                                                                                                                                                                                                                                                                                                                                                      The temperature are tested in an open environment, the surface heating temperature will be higher than 580℃ in the drying oven.   Medium wave quartz infrared emitters are particularly suitable for the fast heating of surface or thin materials, and the range of IR radiation wavelength is 2.2-4.0μm. Meat, herbs, fruits, vegetables and other food in life, paints, plastics sheet or film, water and other solvents in industry, all of their drying processes can absorb well this medium wave infrared radiation. Because of its long working life and economic efficiency, medium wave infrared emitters are popular used in continuous heating processes and long drying machine or drying oven.

Why Promote Quartz Radiant Drying IR Lamp?

Why Promote Quartz Radiant Drying IR Lamp?

Our quartz IR lamps are designed to provide maximum efficiency and reliability for all industrial heating application. Our IR lamps are energy efficient and can provide up to 50% more energy savings compared to traditional heating methods. Our IR lamps are also easy to install and maintain, making them the perfect choice for industrial heating projects. Try our quartz tube radiant infrared lamps today and experience the difference!                                                                                        Why should we promote the use of infrared heat lamps? Because infrared quartz drying IR lamps has four excellent characteristics of "efficient, energy-saving, accurate temperature control and environmental protection".    1. Efficient means fast heating, infrared radiation does not need to contact the product and does not require the intermediate medium to transfer heat compared with hot air, ceramic heaters, gas heaters or metal heaters. The radiant energy of infrared lamp is directly absorbed by material molecules, and the energy density of infrared lamp is very large, the surface temperature of the heated materials will increase quickly. This infrared heating speed is much higher and efficient than the speed of conduction and convection. The latter requires molecular collisions, which are transferred step by step through the conversion of kinetic and potential energy.        Infrared heating has certain penetrability. The wavelength of shortwave infrared heater lamp can penetrate the surface of an object to a certain depth, and when the molecules within this depth absorb the shortwave infrared, they heat from the inside to the outside at the same time. This has great advantages over conduction and convection, not only fast heating, but also to a large extent avoids the phenomenon of surface sealing and blistering.         2. Energy saving means saving money, infrared quartz lamps can be precisely matched to the heated material, that is, effectively absorbed by the material. Different objects different matched IR radiation wavelength-IR lamp Short wave (0.9~1.4μm), Fast response medium wave (1.4~2.0μm), Carbon medium wave (2.0~4.0μm), Medium wave (2.2~4.0μm).     when heating the same size and quantity of heating objects, quartz heating infrared lamp can greatly reduce energy consumption. The infrared heating is more surface heating. As mentioned above, medium wave infrared heater lamp heats the surface of an object very rapidly, so there is a large temperature difference between the surface and the interior of the object. This is a great advantage for the purpose of rapidly heating the surface of an object, as this does not cause large changes in the bulk temperature of the material. Energy saving without having a big impact on the humidity, chemical properties, stress, etc. of the object. But it also has the disadvantage, that is uneven heating for objects with irregular shapes, the disadvantage will cause temperature differences. At this time, we can have hot air in to get a uniform heating with infrared heater lamps.         3. Fast response, adjustable heating temperature   Our quartz infrared lamps are resistnace load and can be adjusted the output power by SCR regulator with accurate ±1℃ heating temperature. For example, if we need 120℃ heating temperature, and the real-time temperature is 115℃ from the temperature sensor, then the temp sensor will return the singal to SCR units and SCR will raise up the heating output power. In opposite,  if the real-time temperature is 123℃ from the temperature sensor, then the temp sensor will return the singal to SCR units and SCR will lower the heating output power of quartz infrared lamps. As the following diagrams, ΔT is smaller and more stable heating temperature we have.           In above, SCR regulators can help us save the output energy and control the heating temperature for different heating applications or heating zones with our infrared heating lamps.                                             4. Environmental Protection, in the process of manufacturing, use, and abandoned infrared radiation lamps is relatively small on the environment. Infrared radiation lamps do not use materials that are harmful to the environment: the impact of the environment during the manufacturing process is small. Infrared radiation lamps consume relatively clean electricity in working, and has no harmful emissions in the process of use.   For a successful heating process, it is important to select a suitable infrared lamp with wavelength, shape and heating power match the product being heated. Precise matching ensures that infrared radiation is quickly converted into heat in the product without transferring unnecessary heat to the surroundings, saving time and money.
