Key points of heat sealing production of double membrane integrated gas cabinet

The key points of heat-sealing production of double-membrane integrated gas cabinets mainly involve the heat-sealing process of the bottom membrane, inner membrane and outer membrane, which is a key step to ensure the airtightness and durability of the gas cabinet. The following is a detailed explanation of the key points of heat-sealing production of double-membrane integrated gas cabinets:

Ⅰ. Membrane material selection and preparation

1.Inner and outer membrane materials:

。The inner membrane must have the characteristics of anti-methane leakage, fire resistance, wear resistance, wrinkle resistance and hydrogen sulfide resistance to ensure the safety and stability of stored gas.
。The outer membrane must have anti-static, anti-ultraviolet, anti-aging and other characteristics to resist the erosion of the external environment.

2.Membrane material specifications:

。According to the design requirements of the gas cabinet, select suitable membrane material specifications, including color, thickness, weight, etc.

。Ensure that the quality of the membrane material meets the relevant standards and requirements.

Ⅱ. Heat-sealing process

1.Heat-sealing equipment:

。Use a large heat-sealing machine for heat-sealing processing to ensure the uniformity and stability of the heat-sealing process.

。The heat-sealing machine must have a precise temperature and time control system to meet the heat-sealing requirements of different membrane materials.

2.Heat-sealing environment:

。Heat-sealing is carried out in a dust-proof workshop to avoid the influence of dust and other impurities on the film material and the heat-sealing quality.

。Keep the temperature and humidity in the workshop stable to improve the heat-sealing effect.

3.Heat-sealing process:

。Place the inner and outer films on the heat-sealing machine according to the design requirements to ensure the flatness and alignment of the film material.

。According to the characteristics of the film material and the parameters of the heat-sealing machine, set the appropriate temperature and time for heat-sealing.

。During the heat-sealing process, pay close attention to the changes in the film material and the heat-sealing quality, and adjust the parameters in time to ensure the heat-sealing effect.

4.Weld treatment:

。Carefully check the welds after heat-sealing to ensure that the air tightness and physical properties of the welds meet the requirements.

。Use special patented technology to process the welds to improve the strength and durability of the welds.

III. Quality inspection

1.Appearance inspection:

。Carry out an appearance inspection on the film material after heat-sealing to ensure that the surface of the film material is flat, wrinkle-free, damage-free and other defects.

2.Air tightness test:

。Carry out an air tightness test on the gas cabinet after heat-sealing to ensure that it can withstand a certain pressure without leakage.

。During the test, relevant data is recorded and analyzed to evaluate the air tightness and durability of the gas cabinet.

3.Performance test:

。Perform performance tests on gas cabinets, including pressure stability, corrosion resistance, etc., are carried out according to relevant standards and requirements.

。Ensure that the performance of the gas cabinet meets the design requirements and use requirements.

The key points of the heat sealing production of the double-membrane integrated gas cabinet involve multiple aspects such as film material selection and preparation, heat sealing process and quality inspection. By strictly controlling the heat sealing process and quality inspection, the air tightness, durability and safety of the gas cabinet can be ensured to meet the use requirements.
