Glass is a hard and brittle transparent object with no definite melting point. Generally made of quartz sand, limestone, soda ash, etc., after being mixed, melted at high temperatures, formed, and cooled. Glass is an indispensable item in life, today and you talk about how to identify the quality of glass and how to order glass should be transported.
Flat glass inspection, the appearance quality is mainly to check the flatness, observe whether there are air bubbles, inclusions, scratches, lines and fog spots and other quality defects, the existence of such defects in the use of glass, deformation will occur, reduce the transparency of the glass, mechanical strength and thermal stability of the glass, engineering should not be selected. Because the glass is a transparent object, it can basically identify the quality after visual inspection when selecting.
Good flat glass products should have the following characteristics: it is colorless and transparent or slightly light green, the thickness of the glass should be uniform, the size should be standardized, no or few bubbles, stones and waves, scratches and other defects.
The inspection of glass processing products, in addition to the requirements of flat glass testing, should also test its processing quality, test whether the size of the standard, processing accuracy and pattern clarity, etc. meet the requirements, while the side is not allowed to have defects.
The original glass that has not been processed by glass is relatively easy to break, and more attention should be paid to it during transportation. Glass transport precautions:
1, in order to avoid unnecessary losses during the transportation process, we must pay attention to fixing and adding soft pads. It is generally recommended to use the upright method of transport. The vehicle should also be careful to maintain a steady, slow speed.
2, the other side of the glass installation is closed, pay attention to clean the surface before installation. It is best to use a special glass cleaner, and to dry to prove that there is no stain before installation, installation is best to use clean construction gloves.
3, the installation of glass, to use silicone sealant to fix, in the installation of Windows, but also need to be used with rubber seals.
4, after the completion of construction, pay attention to the anti-collision warning signs, generally can be used not to paste, color electrical tape to prompt.
5. Do not collide with sharp objects.
