High and low temperature test chamber holiday maintenance

Every holiday, everyone is on holiday, there is basically no one in the factory, have you ever thought about how to maintain the machine? When the high and low temperature test chambers are not expected to be used for a long time, the equipment should be routinely maintained before being placed, which can prolong the life of the high and low temperature test chambers and reduce the maintenance rate. Daily maintenance is as follows:

1. When the machine is not used for a long time, it should be energized every half month periodically. The power-on time is not less than 1 hour.

　　 Second , the operation equipment, drying test area

The high and low temperature test hole is formed, a temperature controller sets, such as 85 ℃, the operation of the machine, inside the remaining water will escape from the test well at a high temperature, ultimately to the drying chamber ;

　　 3. Turn off the main power switch ( leakage circuit breaker ) and cut off the power supply.

1. Close the main power switch ( leakage circuit breaker );

2. If the laboratory door emits a slight popping sound and the test is in progress, it is necessary to change the settings in order not to interrupt the operation or to give an alarm ;

3 , select the operating mode ;

4 , then, press the "Run" button in the fixed value mode, and press the "Execute" button in the next confirmation message box, close the door, let the high and low temperature test chamber run for 60min;

5. Return to step C to change the settings of the device to the initial state.

6. Turn off the main power supply ( leakage circuit breaker ) and then cut off the power supply.

Since the high and low temperature test chambers are basically composed of multiple systems of electricity, refrigeration and machinery, once the equipment has problems, the entire equipment system should be thoroughly inspected and comprehensively analyzed. Generally speaking, the process of analysis and judgment can be performed first and foremost, that is, the external factors are excluded and the equipment is analyzed according to the fault phenomenon. Do not blindly disassemble or replace parts before you find out the cause of the malfunction, so as not to cause unnecessary trouble.

Fluorine-Containing Methylbenzene

Fluorine-Containing Methylbenzene products can be used as herbicides in the manufacture controlling wheat fields, cotton fields and other broadleaf weeds and perennial weeds. It can also be used in the manufacture of antipsychotics drugs.
The Fluorine-Containing Methylbenzene products must be kept under seal, once exposed to light will immediately cause discoloration. It should also be stored in a cool, ventilated warehouse, away from fire and heat. Compartment temperature should not exceed 30 ℃. And make the appropriate technical measures for fire and explosion. Products will Decomposition by high fever and emit toxic gases, such as carbon monoxide, carbon dioxide, hydrogen fluorid. Due to ts vapor is heavier than air, it can spread from low place to far away places. In case of fire conditions, should not fire with water. In case of a small amount of leakage should be evenly sprayed with dilute hydrochloric acid. In case of large spills should build a causeway or trenching asylum. The transfer pump to tankers or exclusive collector, recycling or shipped to the waste disposal sites.
