生产中常见的问题及解决方法以及区别 Talking about common problems in Suzhou tempered glass production and their solutions and differences

In the process of insulating glass production, the common problems are:

First seal:

1. When the butyl rubber is extruded, burrs appear and are not smooth

Approach:

A. If it is a new machine, you should first observe whether the glue holes are smooth. If the glue holes are rough, you should first polish and then try the machine;

B. If it is an old machine, because the temperature sensor of domestic equipment is sometimes insensitive, the displayed temperature does not match the actual temperature, so based on the displayed temperature, it should be adjusted up by a gradient every 5 degrees until the glue is normal (Note: (The rubber head temperature should be about 5 degrees higher than the temperature of the rubber cylinder when setting).

2.Butyl glue does not stick to aluminum strip and glass

Handling method: Usually the reason is that the use temperature is low, it is recommended to adjust the temperature upward to a proper level.

3. After the two seals are completed, a cold flow of butyl rubber appears after a period of time

Solution: This situation generally occurs in the second seal using silicone glue. Unstable silicone glue can easily migrate out of the silicone oil, dissolving the butyl glue, causing the butyl glue to flow. Suzhou glass factory recommends the use of silicone glue that meets standard quality requirements.

4.Break and blockage occurs during extrusion

Solution: This phenomenon is caused by the butyl rubber not meeting the standard quality requirements and too many impurities. It is recommended to use qualified products that meet the requirements of the standard.

Second seal:

1.Slow vulcanization time

Recommendation: The curing agent is a variable category, and the content of the curing agent should be appropriately increased until it is appropriate.

2.Viscosity is high when stirring in winter

Recommendation: Properly increase the construction temperature. In principle, the use temperature should not be less than 5 degrees Celsius.

3. Two sealed non-stick glass, low strength

Recommendation: If the second sealant used is a product that meets the requirements of the standard, there are two reasons for this: A, excessive curing agent, B, uneven stirring. "Symptomatic remedy" can be resolved. If the product used does not meet the standard requirements, non-stick glass and low strength are inevitable. Therefore, the use of substandard products should be strictly prohibited.

Problems and causes of insulating glass finished products

1. Fog inside the insulating glass

Reason l: Due to the unstable quality of the two sealants, the low-molecular content is too high, and it migrates and volatilizes to the inside of the hollow glass under the ultraviolet rays of the sun, causing fogging;

Cause 2: A seal was broken;

Reason 3: The four connection parts are not treated with butyl rubber;

Reason 4: The quality of the desiccant is poor. Under sunlight, it releases low-molecular substances and causes fogging.

2.Insulating glass condensation

Reason 1: the quality of molecular sieve is unstable and the adsorption capacity is low;

Cause 2: One or two seals failed;

Cause 3: The four joints were not handled properly.

3.Hollow glass self-explosion

If it is a large area of self-exploded tempered glass, it is a quality problem of tempered glass. It is also recommended that the glass be ground as much as possible to eliminate stress and reduce glass cracking.

The difference between insulating glass and vacuum glass

1. Vacuum glass:

In 1993, the world's first 1-meter by 1-meter vacuum glass sample came out. The inventors were Tang Jianzheng and RECollins of Peking University Physics.

Vacuum glass refers to the vacuum drawn between two layers of glass. The vacuum layer is relatively thin. In order to achieve a balance between the internal and external pressure of the glass, a flexible or rigid support must be arranged between the glass to support the glass from the external atmospheric pressure Vacuum glass is a custom-made product, which has high requirements due to the atmospheric pressure.

Suzhou Glass Factory tells you that vacuum glass can be likened to a flat-shaped thermos bottle in principle. The common point between the two is that the interlayer of the two layers of glass is a vacuum with an air pressure lower than 10-1pa, so that the gas heat transfer is negligible; both The inner walls are plated with a low-emissivity film to minimize radiant heat transfer. The difference between the two is that the first is that vacuum glass used in doors and windows must be transparent or light-transmissive. It cannot be coated with an opaque silver film like a thermos bottle, and is coated with different types of transparent low-emissivity films. Or the ball-shaped thermos flask becomes a flat plate, and a square of "supports" must be set between the two layers of glass to withstand an atmospheric pressure of about 10 tons per square meter, so that the glass is kept spaced to form a vacuum layer. The spacing of the "support" square array is designed according to the thickness and mechanical parameters of the glass plate, and is between 20mm-40mm. In order to reduce the heat transfer caused by the "thermal bridge" of the support and make it difficult for human eyes to distinguish, the diameter of the support is small. The diameter of the support in the product is between 0.3mm-0.5mm and the height is between 0.1mm-0.2mm. . A better function of vacuum glass is sound insulation. Since there is a vacuum layer, it cannot conduct noise, so vacuum glass can isolate 90% of the noise.

product advantages:

Low carbon energy saving

Heat insulation

3. Sound insulation and noise reduction

4. Keep away from condensation

5. Widely used

Product Category:

Vacuum laminated glass

2. "Vacuum + Hollow" combined vacuum glass

3. "Vacuum sandwich + hollow" structure

4.Double vacuum layer vacuum glass

Insulating glass

Insulated glass was invented by Americans in 1865. It is a new type of building material with good heat insulation, sound insulation, beautiful appearance, and can reduce the weight of the building. It uses two (or three) pieces of glass and uses high strength and high strength. An air-tight composite adhesive, which combines a glass sheet with a desiccant-containing aluminum alloy frame to produce a high-efficiency sound-insulating glass. Insulating glass has a variety of properties that are superior to ordinary double-layer glass, so it has been recognized by countries around the world. Insulating glass is two or more pieces of glass that are evenly spaced with effective support and bonded and sealed at the periphery, so that dry gas is formed between the glass layers. Glassware for space. Its main materials are glass, aluminum spacers, corner plugs, butyl rubber, polysulfide rubber, and desiccant.

Ordinary insulating glass

Suzhou glass factory is composed of two or more layers of flat glass. Use high-strength, high-airtight composite adhesives around the two or more pieces of glass to seal and seal the glass strip. The middle is filled with dry gas, and the frame is filled with desiccant to ensure the dryness of the air between the glass sheets. Various original glass sheets with different properties can be selected according to requirements, such as colorless transparent float glass, heat-absorbing glass, heat-reflecting glass, wire-lined glass, tempered glass, etc. and the frame (aluminum frame or glass strip, etc.). Made by welding or welding.

Insulating glass can be 3, 4, 5, 6, 8, 10, 12mm thick original glass, and air layer thickness can be 6, 9, 12, 15, 18, 21mm.

High-performance insulating glass

High-performance insulating glass is different from ordinary ordinary insulating glass. In addition to the dry air enclosed between the two layers of glass, a special metal film with good thermal properties must be coated on the side of the outer glass intermediate air layer. It can cut off the considerable energy from the sun into the room and play a greater thermal insulation effect. And the interlayer space must be filled with inert gases argon and krypton.
