红外线可分为三部分，即近红外线，波长为0.75～1.50μm之间；中红外线，波长为1.50～6.0μm之间；远红外线，波长为6.0～l000μm 之间。红外线可分为两类：近红外线与远红外线。近红外线或称短波红外线，波长0.76～1.5微米，穿入人体组织较深,约5～10毫米；远红外线或称长波红外线，波长1.5～400微米，多被表层皮肤吸收，穿透组织深度小于2毫米。短波红外线的频率最高，温升较快。ν=λf 红外线烤漆使用辐射加热的方式，红外线烤灯在给油漆表面加热的过程实际是一个热辐射渗透过程，这样在烘烤过程中会让油漆里的水份和溶剂最先蒸发掉，不会使得干固油漆层产生气泡和小孔，所以烘烤效果会更好，能有效地提高油漆表面质量，增加漆膜强度更高且韧性更好。 短波红外烤漆房，他的波长具有很强的渗透力，短波红外线，也叫（近红外），直入漆层，是涂漆层机体（车身外壳）的温度迅速升高产生自发热效应，涂漆层中的水分（或溶剂）则迅速由内向外挥发，油漆涂料化学的振动频率相同时，油漆涂料化学键因发生共振而加大聚合基因的振幅，使交联聚合的几率增大，靠其分子的化学反应，加速漆涂层的固化（由里及表同谓共振）。 短波红外烤漆房漆主要优点：烤漆效率高，其涂层表面的光泽度与丰满度高，镜物更加清晰，涂层附着力强，操作简单安全性高。所以，短波红外汽车喷烤房发明问世，是二十一世纪的“绿色产品”，有“微波炉”的美誉之称，是必然的换代产品。 红外线加热优势及效率,红外线乾燥加热方式在近几年来则以惊人的发展速度被接受，并被实际使用于各层次，主要是红外线干燥方式有下述之优点： 1. 具有穿透力，能内外同时加热。 2. 不需热传介质传递，热效率良好。 3. 可局部加热，节省能源。 4. 提供舒适的作业环境。
Infrared can be divided into three parts, namely, the near infrared wavelength, between 0.75 ～ 1.50 μ m; infrared, between the wavelength of 1.50 ~ 6 μ m; far infrared wavelengths, between 6 ～ l000 μ M. Infrared can be divided into two categories: near infrared and far infrared. Near infrared, short wave infrared, the wavelength of 0.76 ~ 1.5 micron, penetrate human tissue is deep, about 5 ~ 10 mm; far infrared or long wavelength infrared light, the wavelength of 1.5 to 400 microns, by skin absorption, tissue penetration depth is less than 2 mm. The highest frequency of short wave infrared, temperature rise. V = λ f infrared paint using radiation heating, infrared heat lamp to paint surface heating is a heat radiation penetration process, this will make the paint in water and solvent was evaporated in the baking process, does not make the dry paint layer of bubbles and holes, so the baking effect better, can effectively improve the paint surface quality, higher strength and toughness increase film better. Making short wave infrared paint room, his wavelength has a strong penetration, short wave infrared, also called (near infrared), straight into the paint, paint layer is the body (body shell) the rapid temperature rise of self heating effect, coating of water (or solvent) quickly from inside to outside volatile, paint the vibration frequency of the same chemical paint, paint chemical bond due to resonance and increase the amplitude polymerization genes, that the probability of polymerization increases, the molecules by chemical reaction, curing acceleration of paint coating (from the inside and the table with that resonance). Shortwave infrared paint paint paint main advantages: high efficiency, its gloss and plump coating on the surface of high degree, mirror more clear, coating adhesion, simple operation and high safety. So, the shortwave infrared car spray baking real invention, is the twenty-first Century “green products”, “microwave” reputation is known, is the inevitable product of. Making infrared heating advantage and efficiency, infrared drying heating in recent years with the astonishing development speed is accepted, and the actual use at all levels, mainly is the infrared drying method has the following advantages: making 1 penetrating, inside and outside at the same time heating. Making 2 without heat transfer medium to transfer, good thermal efficiency. Making 3 local heating, energy saving. Making 4 provide comfortable working environment. Ma
