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
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
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.
Introduction to the process principle of infrared lamp Paint drying
The spectrum used in infrared lamp Paint drying can be divided into near infrared (wavelength 760-1400), mid-infrared (wavelength 1400-3000nm) and far infrared (3000nm-1mm). The absorbed energy of infrared radiation decreases with increasing wavelength. Infrared curing has the advantages of fast heating, fast curing speed, and good curing quality. However, due to the existence of temperature and moisture gradients,

What exactly is the method of infrared lamp Paint drying
Infrared lamp paint drying is to use a light source that can emit energy in a very narrow wavelength range to heat the coating film that can absorb radiation in this wavelength range. Organic molecules in the coating absorb energy, prompting molecular atoms or groups to vibrate or rotate, thereby increasing the energy inside the substance, inducing physical and chemical changes in the substance, and drying the coating.
