真空干燥箱

的詳細(xì)介紹隨著真空干燥技術(shù)不斷進(jìn)步，在真空條件下控制溫度對樣品進(jìn)行干燥的方法也越來越受到重視，與常規(guī)干燥法相比所具有的優(yōu)勢如下：

1.	the vacuum environment greatly reduced the liquid boiling point which needs to drive out,therefore the vacuum is dry may with ease apply to heat sensitivity material
2.	for the sample that does not be dry easily,such as powder or other pellet form sample,using vacuum dry method may efficiently shorten dry time.
3.	various structures are complex the or other porous sample process of machinery ministry uses vacuum dry function after washing,have no any remnant quality after being dry compley.
4.	use more safety-under vacuum or inertia condition,eliminate oxide compley to meet the possibility of hot explosion.
5.	with dependence air cycle ordinary is dry to compare,powder form sample will not be flowed,air blows or moves.

though,vacuum dry technology has more numerous advantage,but it is more strict that the workmanship of drying oven compares with the relatively complex requirement for product quality with ordinary oven. a permanent company’s accurate kong wen technical and advanced work manship,the product of guaranteeing us may satisfy your needs.

干燥過程控制

the overall vacuum cycle that vacuunm dry process control may offer program to melt need to set hightest and minimum vacuum degree value respectively according to your requirement,may shorten dry time further.for instance:through program control vacuum cycle,set minimum vacuum degree 50pa and biggest vacuum degree 90pa,circulating frequency is six,if by dry,picture shows process.along with each cycle go on,humidity reduces constantly,dry speed accelerates obviously.biggest circutating frequency mayreach ninety-nine times.

features

1.	cuboid chamber maximizes the effective cubage.microprocessor controller for temperature ensures a precise and reliable control.
2.	dual-layer bullet proof toughened glass door ensures absoluy clear observation on ob-jects in chamber.
3.	shutting extent of oven door is adjustable.closed-cellsilicon gasket ensures a high vacuum degree in oven.
4.	the chamber is made of stainless steel(or wire-drawing sheet),which allows a durable service.
5.	storage,heating,testing and drying are all in an environment without oxygen or filled with inert gases,which ensures no oxidation.
6.	minimum heating time is over 50% less than that of traditional vacuum drying oven.

真空度控制

vacuum drying oven adopts the digital technical control vacuum degree of simulated engineering science,"control by hand"becomes historicallong age.you return think the today lever operating valve of by hand in 21 century may control vacuum degree accuray?
through electromagnetism valve full automatic number the vacuum degree that shows control,foryou,offer the vacuum degree control that has effective accuracy more,hope more offer to give your is more up to date information and more conveniences.pass through panel,vacuum degree from 20par is adjustable to 9999pa,adjustable precision is 1pa.panel shows vacuum degree scope for 1pa,is to 9999pa.vacuum sensor is located in and enters angry mouth and the diffenent location of gas outlet,so,the pressure of having guaranteed to stabilize pressure value,not be bullied the influence that flows the most steady pressure value to the operating panel.

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樣品進(jìn)行干燥的方法也越來越受到重視，與常規(guī)干燥法相比所具有的優(yōu)勢如下：

1、	真空環(huán)境大大降低了需要驅(qū)除的液體的沸點，所以真空干燥可以輕松應(yīng)用于熱敏性物質(zhì)
2、	對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間
3、	各種構(gòu)造復(fù)雜的機(jī)械部件或其它多孔樣品經(jīng)過清洗后使用真空干燥法，*干燥后不留任何殘余物質(zhì)
4、	使用更安全--在真空或惰性條件下，*消除氧化物遇熱爆炸的可能
5、	與依靠空氣循環(huán)的普通干燥相比，粉末狀樣品不會被流動空氣吹動或移動

真空干燥技術(shù)雖然有以上眾多優(yōu)點，但干燥箱的制造工藝與普通烘箱相比更為復(fù)雜，對產(chǎn)品品質(zhì)的要求也更嚴(yán)格。精確的控溫技術(shù)和先進(jìn)的制造工藝，保證我們的產(chǎn)品可以滿足您的需要。
