The reasons and treatment methods for uneven particle size of tempered glass produced by glass tempering furnace

Glass tempering furnaces play an important role in the glass processing industry. However, sometimes when using a tempering furnace for glass treatment, we may face a common problem of uneven glass particle size. This issue may affect the quality and performance of glass products. This article will delve into the reasons and treatment methods for the uneven particle size of tempered furnace glass, hoping to be helpful to everyone.

1. what is the main reasons for uneven particle size of tempered glass?

1.1. Different quality of raw materials

The quality of the original float glass material directly affects the performance of the glass. If there are uneven components or impurities in the float glass, the processed tempered glass is easy to have uneven particle size. There may be slight differences in float glass from different batches, which can also manifest as inconsistent particle size during the processing.

1.2. Uneven temperature distribution inside the heating oven furnace

The temperature control of the tempering furnace is one of the key factors to ensure the quality of glass processing. If the temperature distribution inside the furnace is uneven, some parts of the glass will be heated too much while others will not be heated enough, which will lead to uneven glass particle size. This may be caused by damage to the heating elements inside the furnace, uneven layout of heating elements, or control system malfunctions.

1.3. Cooling speed too fast or too slow

After glass processing, the tempering effect needs to be achieved by controlling the cooling rate. If the cooling rate is too fast or too slow, it will affect the formation and distribution of glass particles. Excessive cooling speed may result in temperature differences between the surface and interior, leading to the formation of uneven particles; However, a slow cooling rate may result in uneven particle distribution.

1.4. Unstable atmosphere inside the furnace

The atmosphere inside the tempering furnace has an important impact on the glass processing process. If the atmosphere inside the furnace is unstable, it may introduce oxides or other harmful gases, thereby affecting the uniformity of the glass. This may be caused by malfunctions in atmosphere regulating equipment, improper atmosphere gas ratio, or poor ventilation.

1.5. Improper glass processing parameters

The parameter settings of glass processing are directly related to the quality of the product. If there are errors in setting processing parameters by operators, such as improper settings of heating time, temperature, and cooling speed, it may lead to uneven glass particle size.

2. Treatment method for uneven particle size of tempered furnace glass

2.1. Strictly control the quality of raw materials: Before glass processing, strict screening and testing of raw materials are carried out to ensure uniform composition, reduce impurity content, and fundamentally solve the problem of uneven particle size.

2.2. Optimize the furnace temperature control system: Regularly inspect and maintain the temperature control system of the tempering furnace to ensure the stability of the furnace temperature. The temperature control technology adopted achieves accurate control of furnace temperature, ensuring the uniformity of glass heating.

2.3. Improve the atmosphere inside the furnace: Regularly clean the inside of the tempering furnace, maintain good ventilation, and use appropriate atmosphere adjustment devices. By optimizing atmosphere control, reducing the impact of harmful gases, and ensuring the quality of atmosphere during glass processing.

2.4. Adjust heating time: Adjust the heating time of the tempering furnace reasonably based on the type and requirements of the glass. Ensure that the glass is fully heated in the furnace to achieve the desired particle size and avoid unevenness issues caused by insufficient heating time.

2.5. Regular maintenance and inspection: Establish a regular maintenance and inspection system to comprehensively inspect and maintain the tempering furnace. Timely identify and solve potential problems, ensure the normal operation of equipment, and reduce the risk of uneven particle size.

In summary, the stability and performance of the tempering furnace play a decisive role in the quality of the product. In response to the problem of uneven glass particle size in the tempering furnace, we need to deeply analyze the causes of the problem and take corresponding treatment and preventive measures to improve product quality.
