Drying ovens are divided into two categories: electric blast drying ovens and vacuum drying ovens according to the different drying materials. Nowadays, they have been widely used in chemical industry, electronic communication, plastics, cables, electroplating, hardware, automobiles, optoelectronics, rubber products, molds , spraying, printing, medical, aerospace and colleges and universities and other industries. The huge market demand has made the variety of drying ovens diverse, and the quality of the product structure is not the same. In order to make people understand the drying oven more clearly, we should use a pair of eyes to identify the quality of the drying oven.
First of all, from the structural analysis, the general drying box shell is made of cold-rolled steel plate, but in terms of thickness, the difference is very large. Due to the vacuum environment in the vacuum drying box, in order to prevent the box from being crushed by atmospheric pressure, the thickness of the shell should be 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. In order to facilitate observation, the doors of the drying box are equipped with glass windows. Generally, there are tempered glass and ordinary glass inlaid on the door. The doors of the drying box produced by Wuhan Shangshi are all tempered glass. It is a powerful guarantee for the safety of operators. From the outside to the inside, there are two options for the inner tank of the drying box, one is galvanized sheet, and the other is mirror stainless steel. Galvanized sheet is easy to rust during long-term use, which is not conducive to maintenance; mirror stainless steel has a clean 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 galvanized sheet. The sample rack of the inner tank generally has two layers, which can be added according to customer requirements. Since the quality of the sample rack is made of stainless steel, and the additional racks are not conducive to the circulation of the internal hot air and increase the quality requirements of the fan, the cost of each additional rack is between 300 yuan.
Speaking of temperature, we have to talk about insulation and sealing. At present, the insulation materials of domestic drying boxes are mainly 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 is better than that of fiber cotton. Generally, polyurethane can keep the high temperature in the box stable for several hours. It is worth mentioning that the high thermal insulation performance of polyurethane can effectively Prevent the operator from being scalded by excessive temperature outside the box. When the drying box made of fiber cotton is at high temperature, it can only be controlled and adjusted continuously by the temperature controller to keep the temperature in the box stable, which greatly increases the working strength of the fan and the controller, thereby reducing the service life of the drying box. . In terms of post-maintenance, since the polyurethane is injected into the box as a whole, the post-maintenance is particularly cumbersome. Before maintenance, it is necessary to take out all the polyurethane, and then inject it in after repairing. And fiber cotton is not so troublesome and easy to operate. Finally, from the market, the price of fiber cotton is very cheap, and it can meet most of the thermal insulation requirements, and it is widely used. The sealing of the drying box is generally made of anti-aging silicone rubber, and the sealing effect is very good.
In terms of circulating heating performance, the choice of fans is very important, and there are mainly two kinds of domestic and imported fans. The low-noise and high-performance fan will not produce the same noise as the domestic fan during use, and the circulation effect is good, and the temperature rises quickly. Of course, it can also be selected according to the needs of customers.
