在真空加熱中,可以采用電阻加熱,感應渦流加熱,激光輻照加熱等方式。傳熱基本采用輻射傳熱和傳導傳熱。目前常用的有微波加熱,射頻加熱,感應加熱。?紅外線加熱

紅外線可分為三部分,即近紅外線,波長為0.75~1.50μm之間;中紅外線,波長為1.50~6.0μm之間;遠紅外線,波長為6.0~l000μm?之間。紅外線可分為兩類:近紅外線與遠紅外線。近紅外線或稱短波紅外線,波長0.76~1.5微米,穿入人體組織較深,約5~10毫米;遠紅外線或稱長波紅外線,波長1.5~400微米,多被表層皮膚吸收,穿透組織深度小于2毫米。短波紅外線的頻率最高,溫升較快。ν=λf?紅外線烤漆使用輻射加熱的方式,紅外線烤燈在給油漆表面加熱的過程實際是一個熱輻射滲透過程,這樣在烘烤過程中會讓油漆里的水份和溶劑最先蒸發掉,不會使得干固油漆層產生氣泡和小孔,所以烘烤效果會更好,能有效地提高油漆表面質量,增加漆膜強度更高且韌性更好。??短波紅外烤漆房,他的波長具有很強的滲透力,短波紅外線,也叫(近紅外),直入漆層,是涂漆層機體(車身外殼)的溫度迅速升高產生自發熱效應,涂漆層中的水分(或溶劑)則迅速由內向外揮發,油漆涂料化學的振動頻率相同時,油漆涂料化學鍵因發生共振而加大聚合基因的振幅,使交聯聚合的幾率增大,靠其分子的化學反應,加速漆涂層的固化(由里及表同謂共振)。?短波紅外烤漆房漆主要優點:烤漆效率高,其涂層表面的光澤度與豐滿度高,鏡物更加清晰,涂層附著力強,操作簡單安全性高。所以,短波紅外汽車噴烤房發明問世,是二十一世紀的“綠色產品”,有“微波爐”的美譽之稱,是必然的換代產品。??紅外線加熱優勢及效率,紅外線乾燥加熱方式在近幾年來則以驚人的發展速度被接受,并被實際使用于各層次,主要是紅外線干燥方式有下述之優點:??1.?具有穿透力,能內外同時加熱。??2.?不需熱傳介質傳遞,熱效率良好。??3.?可局部加熱,節省能源。??4.?提供舒適的作業環境。
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

微波對生物體的熱效應是指由微波引起的生物組織或系統受熱而對生物體產生的生理影
Thermal effect of microwave on organism refers to the physical image by microwave induced biological organization or system and heating on organisms
響.熱效應主要是生物體內有極分子在微波高頻電場的作用下反復快速取向轉動而摩擦生熱;體內離子在微波作用下振動也會將振動能量轉化為熱量;一般分子也會吸收微波能量后使熱運動能量增加。?微波是一種電磁波。這種電磁波的能量不僅比通常的無線電波大得多,而且還很有”個性”,微波一碰到金屬就發生反射,金屬根本沒有辦法吸收或傳導它;微波可以穿過玻璃、陶瓷、塑料等絕緣材料,但不會消耗能量;而含有水分的食物,微波不但不能透過,其能量反而會被吸收。?感應加熱

Microwave is an electromagnetic wave. This electromagnetic energy is not only than radio waves are usually much larger, but also a strong “personality”, microwave an encounter took place reflective metal, the metal there is no way to absorb or transfer it; microwave can pass through glass, ceramics, plastics and other insulating material, but it will not consume energy; which contain water of food, microwave not only can not through, its energy but will be absorbed.
