Double-layer glass is a common thing for us. When buying a double-layer glass, in addition to the appearance, everyone is more concerned about the quality of the glass. The performance of the product is a very important experience for users. When the glass is in use, some methods can be adopted to check whether its performance is up to the standard. Next, the glass manufacturer will introduce to you, what methods can be used to test the performance of the double-layer glass.
1, leak test
First unscrew the lid of the cup to see if the lid fits the cup body, then add boiling water to the cup (choose boiling water as much as possible), and then invert the cup for two to three minutes to see if any water seeps out.
2, identification of plastic parts
The plastic used in the double-layer glass cup should be food grade. This kind of plastic has a small odor, a bright surface, no burrs, a long service life and is not easy to age.
3, capacity detection
Because the glass cups are double-layered, the actual capacity of the cup is different from what we see. See whether the depth of the inner tank and the height of the outer layer are not much different (generally 18-22mm).
4, heat preservation test
Because the vacuum double-layer glass adopts vacuum heat insulation technology, it can prevent heat transfer to the outside under vacuum conditions, so as to achieve the effect of heat preservation. Therefore, to check the heat preservation effect, you only need to pour 100 degrees of boiling water into the cup. After two or three minutes, touch each part of the vacuum double-layer insulated glass to see if it is hot. If which part is hot, the temperature will change from That place is lost. It is normal that there will be slight heat in the place like the cup mouth.
When we are buying double-layer glass, we must pay attention to whether the production quality is up to standard. Only when the double-layer glass product meets the above-mentioned standards can we bring a good experience to users. If we buy in large quantities, this requires us to inspect the production qualification of the manufacturer on the spot, so as to obtain the guarantee of quality. The glass itself is a consumable product. Choosing a good quality can extend the service life and give us life. Bring convenience.
