Production processing and quality inspection
1. Original film procurement and cutting
The factory purchases glass raw sheets of specified brand and thickness according to the order requirements. Use a CNC cutting machine for precise cutting.
2. Precision machining process
Grinding: Grind according to customer requirements.
Drilling/slotting: Using precision drilling machines for processing is a technical activity, and edge bursting should be avoided.
Cleaning: All glass must undergo strict cleaning before tempering to ensure that the surface is free of impurities.
Tempering treatment: Heat the glass into a tempering furnace to around 700 degrees Celsius, and then rapidly and uniformly cool it.
This process creates strong compressive stress on the surface of the glass and tensile stress inside, thereby increasing its strength by 4-5 times and ensuring safety (breaking into small particles).
Secondary processing (if necessary): If silk screen printing, lamination, composite hollow, etc. are required, they should be carried out after tempering.
3. Full inspection and labeling
100% quality inspection: including dimensional tolerance, flatness, hole accuracy, whether there are scratches, dents, and other defects. 3C certification mark: For safety glass used in construction, the 3C certification mark will be silk screened or pasted before leaving the factory.
After passing the quality inspection, attach the certificate of conformity, indicating the production date, batch, specifications, and other information.

Monolithic cesium potassium fireproof glass
Single piece potassium resistant fire-resistant glass is a type of curtain wall and window glass used for building exterior walls with fire-resistant functions. It is made by using a special process to comprehensively enhance the chemical and physical properties of float glass. It can maintain a flame temperature of 1000 ℃ for 80-120 minutes without bursting, effectively preventing the spread of flames and smoke. This is beneficial for detecting fires at the first time, allowing people enough time to escape and disperse from the scene, and carry out disaster relief work.
Unidirectional perspective glass
Unidirectional perspective glass is a special type of glass that has a high reflectivity for visible light. It is similar to a regular mirror, and indoor scenery cannot be seen outdoors, but indoor scenery can be seen clearly. When the outdoor environment is darker than the indoor environment, indoor scenery can be seen from outside, and outdoor scenery can also be seen from indoors. The clarity depends on the strength of the outdoor illumination. It is suitable for concealed observation windows, holes, etc. It can be used in special places such as public security stations, detention centers, police stations, prisons, courts, procuratorates, karaoke bars, psychiatric hospitals, etc.
Hollow glass is a glass component composed of two or more pieces of glass, separated by an aluminum frame filled with high-efficiency molecular sieve adsorbent to create a certain width of space, and sealed and bonded with high-strength sealant at the edges. Hollow glass made from low radiation glass is called low radiation hollow glass. It solves the problem of excessive sunlight and heat entering the room in summer, which increases the cooling cost, and in winter, it cannot prevent the leakage of indoor heat energy, increasing the energy consumption of heating. Low radiation glass is produced by coating one or more layers of metallic silver on high-quality float glass substrates, which not only has good energy-saving effects, but also conforms to the world trend of energy-saving, environmental protection, comfort, and beauty in architectural design. And the colors are diverse Nature and elegance meet different design needs.
Bulletproof glass refers to glass that not only has the transparency and image transmission properties of glass, but also has the ability to protect against bullet shooting. It is made by bonding multiple pieces of glass and highly transparent adhesive materials together, and then subjected to high temperature and high pressure. According to the GA165-1997 standard, bulletproof glass is classified into models such as F54, F79, F56, etc. based on its bulletproof ability.
Anti smashing composite glass refers to a transparent glass product that has the transparency and image transmission properties of glass, and does not produce penetrating holes under the attack of specified tools. It is composed of two or more layers of glass and transparent materials, with four levels of anti smashing ability from low to high: A, B, C, and D. The anti smashing composite glass surface is flat, smooth, and the adhesive layer is uniform, with four edges polished and chamfered. The FZB-A16-JT anti smashing composite glass produced by our company has passed the inspection of the Ministry of Public Security of China, and the product quality fully meets the requirements of GA844-2009 standard. We have obtained the approval for the production registration of technical defense products from the Zhejiang Provincial Public Security Department.
Composite fire-resistant glass is a special type of glass composed of two or more layers of ordinary float glass as the outer layer, with transparent fire-resistant and flame-retardant adhesive injected in the middle. Its fire prevention principle is that under fire conditions, the fire-resistant and flame-retardant adhesive gradually foams and expands until it carbonizes, forming a protective layer with very low thermal conductivity and good thermal insulation performance, preventing the flame from spreading to the back fire zone, reducing the heat radiation of the flame on the back fire surface, thus protecting the integrity of the back fire surface items and playing a role in safety and fire prevention. The transparent fire-resistant and flame-retardant adhesive is made of self-made crosslinking agents and oxidation-reduction two-component initiators. The composite fire-resistant glass with stable appearance, wide temperature range, good fire resistance, transparency, heat resistance, cold resistance, UV radiation resistance, impact resistance and other comprehensive properties is produced by grouting method.
