Vacuum deaeration machine, also called (vacuum box, vacuum deaeration tank, the epoxy resin deaeration, LED deaeration machine, vacuum machine, vacuum bubble machine, etc.)working principle as follows:
Vacuum deaeration machine should be used with vacuum pump, can completely off process of bubbles.Through the vacuum pump, vacuum pressure of the casing to the negative situation, displays its vacuum degree in vacuum negative pressure value, at this point, chemical material gule , if the molecular composition of the molecular gap is too big, known as bubble, by pumping air into vacuum state, to take it.Principle is very simple, but it’s good vacuum box also need to cooperate, otherwise, also can not the suck bubbles.Box sealing ability must be very good, 2X-A series rotary vane vacuum pump is used to suction than specific gases in sealed container, the container get certain basic equipment, vacuum, it is widely used in the vacuum deaeration industries, is one of the equipment of vacuum deaeration tank is indispensable.
Deaeration box method of use: glue heating vacuum deaeration tank suction vacuum first and then heating :
1: the artifacts into the vacuum chamber is to can go to smoke gas in the smoke to the workpiece material composition.If the first heating workpiece, gas will be heated inflation.As a result of the vacuum box sealing is very good, expanding gas pressure generated by the window has the potential to observe blowout of toughened glass.This is a potential danger.According to the vacuum first, then heating heating program operation, can avoid the danger.
2: if the heating heating and vacuum program operation, heating the air by a pump, heat will be brought to the vacuum pump, which leads to the temperature rise of the vacuum pump is too high, has the potential to roots vacuum pumpefficiency decline.
3: when heated gas by vacuum pressure gauge, vacuum gauge can produce temperature rise.If the temperature exceeds the stipulated by the vacuum pressure gauge temperature range, can make the vacuum pressure gauge produces error value.The correct method of use should be first vacuum heating heating again.Stay after reaching the rated temperature such as found that the vacuum degree decreased when appropriate and smoke.To do so is beneficial to prolong the service life of equipment.
Vacuum deaeration application : glue vacuum deaeration tank
Glue vacuum deaeration tank is designed for drying thermal sensitive, easy to decompose and oxidative material and design, work can make work indoor keep certain vacuum degree, and to internal inert gas, especially of some compound material can also be a quick drying, using intelligent digital temperature control instrument for temperature setting, display and control.
