1.Look at the logo and check the certificate.
Since the safety glass product certification was carried out in 2003, most of the construction laminated glass manufacturers in China have passed the product certification. The enterprises must screen or paste the 3C mark on the product itself, or add the 3C mark on the minimum package and the attached documents (such as the certificate). When choosing a product, first check whether there is a 3C logo, and check whether the product purchased is within the scope of the enterprise's ability to pass the compulsory certification through the network according to enterprise information, factory number or product certification certificate, and whether the certification certificate is valid.
2.Look at the quality of appearance inspection
To check the appearance quality of the product, laminated glass should not be cracked or degummed; the length or width of the exploding edge should not exceed the thickness of the glass; scratches and abrasions should not affect the use; defects such as bubbles, impurities or other observable opacity in the intermediate layer should not exceed the requirements of GB/T 15763.3.
In the course of using, the impact of external force should be avoided as far as possible, especially the impact of toughened sandwich glass should be avoided. Do not scratch or scratch or abrasion the glass surface when cleaning the glass, so as not to affect its optical performance, safety performance and aesthetic. Neutral glass should be used when installing laminated glass. No contact with acidic adhesive is strictly prohibited.
