Insulating glass is a glass product with excellent properties such as heat insulation, sound insulation, and anti-fog. It is widely used in construction, home furnishing and other fields. Its production process needs to go through multiple process steps, including glass cutting, glass cleaning, glass inspection, glass coating, insulating glass assembly, vacuum adsorption, gas injection filling and sealant curing. Every process step is very critical. Only when each step is handled well can high-quality insulating glass products be produced.

How to Make Insulated Glass? Insulated Glass Production Process, Insulating Glass Manufacturing Process

1. In the process of glass cleaning, it is necessary to use professional cleaning equipment and cleaning agents to ensure that the glass surface is clean and smooth, and to avoid defects or affect its performance in the subsequent process. Some large insulating glass production lines will also be equipped with automatic cleaning equipment, which can improve production efficiency and cleaning quality. At the same time, it is also necessary to pay attention to safety issues during the cleaning process to prevent workers from being injured.

2. In the glass inspection process, optical equipment is usually used to inspect the glass surface. These devices can detect various defects on the glass surface, such as cracks, blemishes, bubbles, etc. The defective glass plates will be rejected to ensure the reliable quality of the produced insulating glass products. At the same time, these optical devices can also detect whether the size and shape of the glass plate meet the requirements, so as to ensure the assembly accuracy of the insulating glass.

3. In the fourth process of the insulating glass production line, glass coating is a very important step. Through coating treatment, the heat insulation and sound insulation performance of insulating glass can be effectively increased, and its use effect can be improved. The main technologies used in glass coating are hot-dip method, spraying method and ion plating method. Among them, the ion plating method is a relatively advanced technology, which has the advantages of uniform coating and high precision of thickness control. In addition, the material of the coating is also very important. Common coating materials include zinc oxide, fluorocarbon, etc.

4. During the assembly process of insulating glass, two or more glass plates need to be assembled together according to a certain distance, and sealant strips are installed at both ends to form a closed hollow structure. When assembling, it is necessary to pay attention to the distance between the glass plates should meet the design requirements, otherwise it will affect the performance of the insulating glass. At the same time, when installing the sealing strip, it is necessary to ensure the quality and bonding effect of the sealing strip to ensure the airtight performance of the insulating glass.

5. In the process of making insulating glass, vacuum adsorption is a very critical step. By extracting the gas in the hollow part, the heat conduction can be reduced and the heat insulation performance of the insulating glass can be improved. Usually, the time of vacuum adsorption needs to be determined according to the size and thickness of the insulating glass, so as to ensure that the pressure of the hollow part reaches a predetermined value.

6. After vacuum adsorption, gas injection filling is required immediately, and the desired gas is poured into the hollow part. In this way, gas leakage can be avoided, and at the same time, it can ensure that the insulating glass has good heat insulation and sound insulation performance. In the gas injection filling process, the desired gas (such as argon, air, etc.) needs to be injected into the insulating glass. When injecting gas, it is necessary to ensure the accuracy and uniformity of the amount of gas injected to avoid bending or breaking the glass plate due to uneven gas pressure inside the insulating glass. At the same time, the insulating glass needs to be pre-vacuumized before gas injection to ensure that there are no bubbles and impurities inside the glass. After the gas injection is completed, the insulating glass needs to be cured with sealant to ensure its airtight performance.

7. Sealant curing: Carry out sealant curing treatment on insulating glass to ensure its airtight performance.

8. Insulating glass inspection: conduct a comprehensive inspection of the manufactured insulating glass to ensure that its sealing performance, heat insulation performance and other indicators meet the requirements.

9. Finished product packaging: Pack the insulating glass that has passed the test according to certain specifications, and carry out quality identification and transportation identification.

10. Product storage: Put the packaged insulating glass into the warehouse for storage, and pay attention to moisture-proof, sun-proof, shock-proof and other measures to ensure that its quality will not be affected.
