1. Advantages of vacuum drying oven: dry and fast drying under low temperature conditions, higher cost than blast drying oven, but short drying time and low temperature.
2. Drying characteristics: avoid damage and oxidation during the drying process, avoid dust particle damage and heat the air to destroy the external material structure of the article.
That is, by placing an A4 white paper in the position of the vacuum drying box door, the sealing property of the empty drying box door is judged by the free fall condition of the paper, thereby inferring the rigor of the manufacturer's product details.
2 Process temperature control options: vacuum oven temperature range is up to 250 ° C, blast drying oven up to 300 ° C. In this process, the higher the temperature, the higher the product cost. When the temperature is between 250 °C and 300 °C, the aging of the test chamber and the poor test chamber will be accelerated. At this time, it is necessary to select the products of the regular manufacturer. Guarantee test quality
Purchase budget: blast drying oven is much cheaper than vacuum drying oven. If you want to buy cheaper products, it is recommended to buy blast drying oven. Disadvantages: blast drying oven can easily damage the surface of dry samples.
Vacuum drying oven precautions
Nowadays, the products in the market are mixed. First of all, pay attention to the material of the vacuum drying oven. Most unscrupulous merchants use the 202 liner to act as stainless steel. It will rust after one year. The small manufacturer will use the warranty for three years as a scorpion. Actually, problems arise and shirk responsibility. We must carefully select the manufacturers and try not to choose products in remote areas. The quality of Shanghai and Guangdong products can be regarded as first-class. Don't buy products that are lower than the average market price. If you are a businessman, you don't have to say much. It's definitely a small and cheap one.
