The total thermal resistance of this structure can be regarded as the sum of the thermal resistances of two pieces of vacuum glass. If it is a vacuum glass of the same structure, the total thermal resistance is twice that of a single vacuum glass.
That is, R double vacuum = 2R
Where R is the thermal resistance of a single vacuum glass
For example, the vacuum glass of No. 3 in Table 2 is taken as an example to form a double vacuum as shown in FIG. 6A “4L+0.15V+4+0.15V+4L†or as shown in FIG. B “4L+0.15V+4L+0.15V+4â€. glass.
Then R double vacuum = 2 × 1.06W-1m2K = 2.12 W-1m2K
Can calculate the K value of 0.44 Wm-2K-1
It should be noted that the positions of the Low-E films in the two structures A and B in Fig. 6 are different, and the K value is not affected, and only the temperature distribution of the three pieces of glass in actual use is affected.
Double vacuum glass has high thermal resistance, low K value, and is very thin, can be about 9mm thick, and can also be made into double vacuum layer laminated safety glass, which has good development potential.
Mild steel, sometimes referred to as carbon steel or ordinary carbon steel, is defined as having a carbon content of no more than 2% and no other perceptible alloy elements.
This steel is produced on a large scale and is the largest part of the steel production industry. You will be able to find it in various applications, fasteners and fasteners.
Generally, this kind of steel has high strength, high hardness and magnetism, and is usually used in motors and electrical appliances - however, their corrosion resistance is poor, and should not be used in corrosive environment without protective coating or coating.
There are some differences between low-carbon steel and steel, because steel has lower toughness and greater brittleness, and low-carbon steel can be further strengthened by adding carbon.
