GX-MF900 semi-automatic vacuum sealing performance tester

Application and classification of sealing instrument

The sealing tester is widely used for sealing test of packaging bags, bottles, tubes, cans, boxes, etc. in food, pharmaceutical, medical devices, daily chemicals, automobiles, electronic components, stationery, military and other industries. It can also be used to test the sealing performance of the test piece after the drop and pressure test.

GX-MF900 semi-automatic vacuum sealing performance tester adopts domestic high-quality shockproof pressure gauge, test time can be set at will, and has automatic bleeding function, manual control of test air pressure. Manual operation is required for pressurizing/stopping/timing, and solenoid valve is used to open/close the air circuit. It does not have the function of pressure compensation and balance, and conforms to the national standard.

GX-MF900 semi-automatic vacuum sealing performance tester

The sealing performance tester has a beautiful appearance, the shell is made of high-quality stainless steel, the air seal opening and closing parts are all made of domestic/imported parts, and the sealing performance is better than that of similar domestic models. The test setting time prompts, and the set vacuum value is maintained for a long time.

test method

According to GB/T 15171, put an appropriate amount of distilled water into the vacuum chamber, and then immerse the product in water. Cover the sealing cover of the vacuum chamber, and the distance between the top of the sample and the water surface shall not be less than 15 mm. Use one of the following values: 20, 30, 50, 70, 90 kPa and other negative pressure values to maintain the vacuum for 30 seconds. The vacuum value used shall be determined according to the characteristics of the sample (such as packaging materials used, sealing conditions, etc.) or the provisions of relevant product standards. During the test, pay attention to observe the leakage of the sample when the vacuum is formed and during the vacuum holding period, observe whether there are continuous bubbles at the product seal, and the occurrence of isolated bubbles is not considered as leakage.

The quality of the packaging bag is measured by the tightness measurement, and then the rationality of the packaging process is judged.

Performance characteristics of semi-automatic model: (distinguish between watching video and watching live broadcast or watching live broadcast back)

1. It has all functions of manually operating the model.

2. It has the function of quick pressure supplement. Press the start button directly to complete the pressure supplement, which is more convenient to operate.

3. It has the function of rapid pressurization. Press the start button directly to complete the pressurization, and the operation is more convenient.

4. It adopts electronic control to maintain pressure, which is superior to manual switch type full sealing function, easy to operate and stable in performance.

5. It has the function of automatic blowback to reach the test time after timing, which is superior to the manual operation model.

6. Compared with the manual operation model, the operation is simpler and more stable. It is an upgraded product of manual sealing instrument.

Prompt: The execution standard of manual model, semi-automatic model and fully automatic model is the same as the relevant parameters
