Meihuayi explains the classification and performance characteristics of the drying oven
Drying box is divided into two categories, electric blast drying oven and vacuum drying box. It has been widely used in chemical industry, electronic communication, plastics, cable, electroplating, hardware, automobile, photoelectric, rubber products. Mold, spray, printing, medical, aerospace and higher education institutions. The huge market demand makes the variety of drying boxes diversified, and the quality of the products is not the same. In order to make people understand the drying box more clearly, the quality of the drying box is distinguished by a pair of eyes.

Quality discrimination
Drying boxes are divided into electric blast drying ovens and vacuum drying boxes according to different dry substances. Nowadays, they are widely used in chemical, electronic communication, plastics, cable, electroplating, hardware, automotive, photoelectric, rubber products, molds. , spraying, printing, medical, aerospace and higher education institutions. The huge market demand makes the variety of drying boxes diversified, and the quality of the products is not the same. In order to make people understand the drying box more clearly, the quality of the drying box is distinguished by a pair of eyes.
First of all, from the structural analysis, the general dry box casing is made of cold-rolled steel, but the thickness will vary greatly. Due to the vacuum environment inside the vacuum drying box, in order to prevent the atmospheric pressure from crushing the box, the thickness of the outer casing is slightly larger than that of the blast drying box. Generally, the thicker the steel plate, the better the quality and the longer the service life. For the convenience of observation, the door of the drying box is provided with glass windows, generally with tempered glass and ordinary glass on the inlaid door. Wuhan is still measuring the production of dry box doors, all of which are made of tempered glass. Although the price is slightly expensive, the appearance is beautiful. It is a powerful guarantee for the safety of operators. From the outside and inside, the inner tank of the drying box has two options, one is galvanized sheet, and the other is mirror stainless steel. The galvanized sheet is easy to rust during long-term use, which is not conducive to maintenance; the mirror stainless steel has a neat appearance, is easy to maintain, and has a long service life. It is a high-grade liner material on the market, but the price is slightly higher than that of the galvanized sheet. The sample rack of the liner is generally two layers and can be added according to customer requirements. Since the quality of the sample holder is made of stainless steel, and the increased shelf is not conducive to the circulation of the internal hot air, and the quality requirements of the fan are increased, the cost per additional shelf is between three hundred yuan.
Speaking of temperature, I have to talk about insulation and sealing. At present, the insulation material of domestic dry box is mainly made of fiber cotton, and a few use polyurethane. Let's talk about the different characteristics of the two materials. In terms of thermal insulation effect, the temperature resistance and thermal insulation effect of polyurethane are better than that of fiber cotton. Generally, polyurethane can keep the high temperature inside the box stable for several hours. It is worth mentioning that the efficient heat insulation performance of polyurethane can effectively Prevent the operator from overheating the outside of the box. When the fiber-reinforced cotton drying box is at high temperature, it can only be controlled and adjusted by the temperature controller to keep the temperature inside the box stable, which greatly increases the working strength of the fan and the controller, thereby reducing the service life of the drying box. . From the perspective of post-maintenance, since the polyurethane is completely injected into the box body, it is particularly cumbersome to repair in the later stage. Before the maintenance, all the polyurethanes need to be pulled out, and then repaired and then molded. Fiber cotton is not so troublesome and easy to operate. Finally, from the market, the price of fiber cotton is very cheap, and can meet most of the insulation requirements, widely used, Wuhan still test recommendations: the finer the fiber cotton, the greater the thickness, the higher the insulation quality. The sealing of the drying box is generally made of anti-aging silicone rubber, and the sealing effect is very good.
In the cycle heating performance, the choice of fans is crucial, mainly domestic and imported two types of fans. The low-noise and high-performance fan will not generate noise like the domestic fan during use, and the cycle effect is good and the temperature rises quickly. Of course, the specific can also be selected according to the needs of customers.
