1. Look at the appearance: The surface of the coiled material should be smooth, with no holes, edges and cracks, and flaws. The tire base should be soaked. There should be no unsaturated streaks, no obvious oil leakage at the end, uniform thickness, and standing end. The Department shall have no apparent deformation, and the marks shall be complete.
2, by hand: hand bending, the normal temperature, the coil is flexible, does not produce cracks, and should not be brittle.
3. Flexible temperature measurement: Take 10 specimens of 150mm x 25mm in the longitudinal direction of the coil, and place it in the refrigerator at the specified temperature for 2 hours according to the type of the mark. After bending, see if there is cracking or cracks. Good products do not crack.
4, than the price. Due to the quality of the base material, relatively low-priced quality is relatively poor, and tension and elongation may not meet the standard requirements. It is recommended to select some large-scale well-known manufacturers of products, although the price is higher, but the quality is relatively good.
ICESUN Vacuum Glass LTD. adopts the unique vacuum eye technology to produce Gen3 vacuum glass with mirror eye. This mirror eye technology refers to place the nano active sodium barium film with the size of pupil in the vacuum chamber. When it encounters trace gas, the eye of vacuum glass would immediately undergo chemical reaction and change from black and bright mirror into white powder. The disappearance of the mirror eye indicates the increase of conduction and convection in the vacuum glass, and also indicates that the Low-E film will soon be oxidized and fail, and the radiation heat transfer would greatly increase. That is to say, the building glass will fail. Therefore, users can easily know the service life of their own windows at any time through installing our Vacuum Glass For Buildings. Besides, our company also provide other good quality and high performance Vacuum Glass For Transportation like cars, Vacuum Glass For Passive House, Vacuum Glass For Sun Room and skylight, etc.
