Koji su čimbenici koji utječu na cijenu laboratorijske muflne peći?

1. The process is different: its muffle furnace directly uses fiber wool to install the silicon carbide hearth inside the furnace shell, does not use ceramic fiber board as an insulation layer, and does not use two-layer sheet metal as an air cooling system. The surface temperature of the electric furnace on the experimental site has exceeded 150°C. The temperature of the door handle has exceeded 80°C, so you can’t touch it directly with your hands, and you need to wear high-temperature gloves before you can experiment. The ceramic fiber board is used for the secondary insulation layer, and the air cooling system is equipped in the middle of the double-layer shell, so that the surface temperature of the muffle furnace is as low as 50°C. Suppliers who do not use ceramic fiber board insulation materials and do not use two-layer shell can save about 500-1000 yuan.

2. The sheet metal is different: the low-priced sheet metal of the muffle furnace is made of 1mm thick iron sheet metal, and its robustness and reliability are greatly reduced. The quality can be imagined, the difference between good and bad sheet metal is at least 1,000 yuan.

3. Safety performance: From the protection of the electric circuit to the reliability of the sheet metal and the use of the An Guangshu experimental electric furnace, there are great improvements. Don’t improve the details, such as the door handle: after 5 improvements, the muffle The tightness and reliability of the furnace door can meet the safety standards, while the low-priced products of the muffle furnace cannot be closed normally. Each time the door is closed, it takes effort and time, and the furnace door has poor tightness. Large gaps, doors are often automatically opened in the middle of the experiment, which seriously affects the accuracy of the experiment and serious safety problems.
