1. Check the appearance quality of the product
Tempered glass should not have cracks or missing corners; Explosions and scratches should not exceed the requirements of GB15763.2-2005 standard. At the same time, the quality of the glass raw materials used in the production of tempered glass should meet the requirements of the corresponding product standards. The appearance quality defects of tempered glass caused by internal defects of the glass raw materials should meet the requirements of the corresponding product standards. In addition, check the flatness of the flat tempered glass. For flat tempered glass products, the GB15763.2-2005 standard requires that the bow curvature should not exceed 0.3% and the waveform curvature should not exceed 0.2%.
2. Look at the logo to check the certificate
Since the implementation of safety glass product certification in 2003, the majority of building tempered glass production enterprises in China have passed product certification. Enterprises must silk screen or paste the 3C logo on the products they sell, or add the 3C logo on their minimum outer packaging and accompanying documents (such as certificates of conformity). When selecting a product, the first thing to check is whether it has the 3C mark, and based on enterprise information, factory number, or product certification certificate, check online whether the production enterprise of the product has passed mandatory product certification (with a valid 3C certificate), whether the product model and specifications are within the scope of the enterprise's ability to pass mandatory certification, and whether the certification certificate status is valid.
3. Check the inspection report of the product
Tempered glass used in construction, as a product that affects personal and property safety, has always been listed as a key focus of government supervision and inspection. Regular manufacturers are subject to periodic inspections by regulatory authorities. Therefore, production enterprises should be able to provide inspection reports issued by the quality inspection department, otherwise, the quality of the product lacks a basis.
4. Cleaning and maintenance of tempered glass
Tempered glass has the characteristics of heat resistance, wear resistance, scratch resistance, impact resistance, easy cleaning and maintenance, and crystal transparency, and is increasingly popular among people. The maintenance techniques for tempered glass dining tables should start from the following aspects: avoiding exposure to sunlight and rain; Regularly maintain cleanliness; Do not use force to collide with the glass surface. When placing something on it, handle it gently; To prevent scratches on the glass surface, it is best to lay a tablecloth on the table; For tea and other items that fall onto the dining table, they should be wiped dry in a timely manner, otherwise over time, they will leave unsightly stains.
5. Observe the surface condition of tempered glass
Tempered glass is processed and produced again on the basis of ordinary glass, and the natural effect will also be different. The products produced by different tempered glass manufacturers also have different effects, and it requires very patient selection. The first step in selecting tempered glass is to observe the surface condition of the tempered glass to determine the quality of the product. Use the light of the sun and then wear polarized sunglasses to look at the glass. At this point, you will see colored stripes on the surface of tempered glass, which are not visible on regular glass. You can also observe the side of the glass with the naked eye. Tempered glass has a blue color on the side, while regular glass does not. By observing, it is possible to determine whether it is tempered glass .
6. View certificate
No matter which tempered glass manufacturer, any product produced from the factory has relevant certificates. Most tempered glass manufacturers have passed the national production standards and obtained product certification. Therefore, when choosing tempered glass, one can observe whether there is a CCC mark on the surface of the glass, or whether there is a certificate of conformity attached to the packaging. With these certificate marks, there is no problem with the quality of tempered glass. If unsure, you can search through the official website. By viewing the certificate, one can understand the quality of tempered glass, which serves as a standard and basis for selection.
7. View enterprise information
The tempered glass sold in the market is certified by the relevant national authorities, and the quality of the products is beyond doubt. Therefore, when purchasing, it is necessary to check whether the tempered glass is pasted with the CCC logo. Through this sign, you can learn about the information of the enterprise, factory number situation, and so on. By searching online, you can see this information very clearly. If the information found is accurate, it indicates that the quality of tempered glass is not a problem, and you can choose 2 with confidence.
8. Check the flatness
When purchasing tempered glass, you can check the surface flatness. The surface of tempered glass is uneven, and the flatness is much worse than ordinary glass. Meanwhile, by observing the longer side of the glass, if it is curved, it is tempered glass, otherwise it is not. Good tempered glass has a certain degree of curvature, but the size of the curvature has a certain standard. Exceeding the standard by 0.3% will affect the quality of use.
9. Check if it has undergone homogenization treatment
Self explosion is an inherent characteristic of tempered glass and is difficult to avoid. But if homogenization treatment is used, more than 90% of self explosion hazards can be eliminated. When selecting, be sure to refer to the product manual to determine if it has undergone homogenization treatment
