With the development of society and economy and the progress of science, the glass industry continues to progress. While developing new varieties, the types of existing glass have also been strengthened. Various types of deep-processed glass have gradually replaced ordinary flat glass, and have played an important role in various application fields. In order to get good quality and reasonably priced glass, we need to have a certain understanding of it. Let's take a look at how to package and ship glass.
How is glass packaged?
Glass is generally packed in containers or wooden boxes. Each piece of glass is packed in plastic bags or paper, and filled with light and soft materials that do not easily cause appearance defects such as glass damage between the glass and the box. Specific requirements should meet the relevant national standards.
Packaging glass requires a packaging mark and must comply with the relevant national standards. Each packaging box will be marked "upward, lightly handled, carefully broken, glass thickness, grade, and manufacturer's name or trademark, etc.
How glass is transported
的 Various transportation vehicles and transportation rules used for transportation of products shall comply with relevant national regulations.
During transportation, the wooden box cannot be placed horizontally or inclined, and the length direction is the same as the movement direction of the transportation vehicle. Measures such as protection against rain are required. Storage products must be stored in a vertically dry room.
It turned out that a small piece of glass was shipped with so much knowledge in it. It's really insightful, you, remember!
Glass is currently widely used in construction, daily use, art, instrumentation and other fields, and there are many types. In addition to common tempered glass and printed glass, there are also optical glass and dimming glass with high technical requirements.
What we are going to introduce today is the difference between laminated glass and insulating glass.
Laminated glass and insulating glass are made of two or more pieces of glass, but the methods and methods used in the composition are different.
Laminated glass is made of transparent plastic liner between two or more pieces of glass, and then manufactured in industries such as thermocompression bonding stations. In addition, the laminated glass is generally ordinary flat glass or float glass, and the transparent plastic lining is a plastic film such as polyvinyl butyral.
Insulating glass is separated by an isolation frame around two or more pieces of glass and then sealed with a sealing tape. The glass used is flat laminated glass, tempered, endothermic, heat reflective, embossed and other glass; in order to meet the performance requirements of insulating glass, The sealing tape is a two-component sealant; the spacer frame is an aluminum frame, a stainless steel frame, and the like.
So how do I choose?
Laminated glass and insulating glass both have a sound insulation effect to a certain extent. However, laminated glass has very good shock resistance and explosion-proof performance, and insulating glass has better thermal insulation.
In terms of sound insulation, there are also different differences between the two. Due to the good seismic performance of laminated glass, when the wind is strong, the possibility of noise caused by its own vibration is very low, especially for low and medium frequencies. And hollow glass resonates easily. However, when blocking external noise, insulating glass is better. So depending on the location, the choice of glass is different.
If it is for ordinary household use, insulating glass is a wide choice. If you live in a high-rise building with strong wind and low external noise, laminated glass is also a good choice.
If it is applied on a sunny room. The top of ordinary sun room uses laminated double-layer tempered glass. For facades, insulating glass is generally used.
Laminated glass has higher safety if it encounters falling objects, and it is difficult to completely shatter it. The facade glass uses insulating glass, which can achieve the effect of heat insulation and keep the sun room warm in winter and cool in summer.
Therefore, we can't say that laminated glass and insulating glass are better, but we can only say which aspect is in great demand. The window glass is the knight who protects the house.
