隨著真空干燥技術(shù)不斷進(jìn)步，在真空條件下控制溫度對(duì)樣品進(jìn)行干燥的方法也越來(lái)越受到重視，與常規(guī)干燥法相比所具有的優(yōu)勢(shì)如下：
1、真空環(huán)境大大降低了需要驅(qū)除的液體的沸點(diǎn)，所以真空干燥可以輕松應(yīng)用于熱敏性物質(zhì)。
2、對(duì)于不容易干燥的樣品例如粉末或其它顆粒狀樣品，使用真空干燥法可以有效縮短干燥時(shí)間。
3、使用更安全一一在真空或惰性氣體條件下，完全消除氧化物遇熱爆炸的可能。
4、與依靠空氣循環(huán)的普通干燥相比，粉末狀樣品不會(huì)被流動(dòng)空氣吹動(dòng)或移動(dòng)。
DZF型 真空干燥箱(Model DZF Vacuum Drying Oven)
一、適用范圍：
適用于工礦企業(yè)、醫(yī)學(xué)院校、科研單位在真空條件下對(duì)物品進(jìn)行干燥熱處理等。
二、產(chǎn)品特點(diǎn)：
1、長(zhǎng)方體工作室采用優(yōu)質(zhì)鋼板或不銹鋼板。鋼化、防彈雙層玻璃門觀察工作室內(nèi)物體一目了然。
2、箱門閉合松緊能調(diào)節(jié)，整體成型的硅橡膠門封圈，確保箱內(nèi)高真空度。
3、微電腦智能控溫儀，具有設(shè)定，測(cè)定溫度雙數(shù)字顯示和PID自整定功能，控溫，可靠。
4、加熱功率比例可任意調(diào)節(jié)，確保低端控溫?zé)o溫度之弊。
一、Suitable Scope
It is applicable to such tests as drying heat treatment.ect.of artides under vacuum conditions in industrial and mining enterprises as well as in nedical colleges and scientific research institues.
二、Characteristies of product
1、 The working chamber is ，made of high quality sheet or corrosion-resistant stainless steel.Toughened hulletproof double glass door,to observe clearly the object in the working chamber.
2、 The air-tightness of the chamber door is adjustable,with a wholly shaped silicon rubber door sealing loop;so as to guarantee in-chamber high vacuum.
