The use of traditional freezers needs to consume a large amount of conventional energy, causing more and more serious pollution to the environment indirectly. Judging from China's current energy supply and environmental protection needs, the development of freezers using clean energy will be the general trend. In addition, many remote areas and nomads in China have not yet been included in the power supply network and are not yet in a position to use freezers to preserve food. These also provide a potential market for the development of solar DC freezers.
However, there are also various factors restricting the wide application of solar DC freezer refrigeration technology at this stage. On the one hand, due to the low efficiency,... less
The stainless steel hose is made of stainless steel SUS304 or SUS301. It is used as a protective tube for wires, cables, optical fibers, and signal lines of automated instruments.

The force is the pressure when closing the mould, the pressure of the melt in the mould cavity and the pulling force when opening the mould, etc. The pressure of melt is the main factor. The dustbin mould generally works at a certain temperature and the temperature fluctuates.
In addition, the dustbin mould will be rubbed by plastic and possibly corroded by corrosive gas when working. The working conditions of the dustbin mould are relatively harsh. To ensure the mould has a certain service life, the dustbin mould material, especially the moulding part material, must meet certain requirements.
First, the mechanical processing performance is excellent: the steel grade which is easy to cut and can obtain high precision after processing is selected, medium carbon steel... less

In the past, we used traditional street lights, but now the traditional street lights are gradually eliminated and solar lights have become popular products. Compared with traditional street lights, what are the advantages of solar lights? Why can traditional street lights be gradually replaced? Let the solar lights manufacturer https://www.nbloyal.com/ tell you:
1. Low input cost
Traditional street lights are much more complicated than solar lights in paving projects. It can not only dig holes but also lead the way. Human and material resources are very expensive. The electricity cost of traditional street lights is very high and the cost is relatively high.
2. Reliable quality
Solar light, because its circuit power supply is made of high-quality components, each LED has a separate overcurrent protection, don't have to worry about damage. More importantly, it has good waterproof and impact resistance, and its quality is... less
1. Check whether the cup seal labels have burrs, the edge of the roll self-adhesive is smooth and undamaged, and the important standard for the quality of the time-difference self-adhesive label. Before printing, be sure to carefully check the cutting edge and burrs of the self-adhesive label. Repair shall be carried out regardless of the damage caused by improper storage or other reasons.
2. Check whether there is adhesion on the edge of the adhesive. The backing sheet is coated with silicone. A part of silicone oil will leak in the adhesive coated area on the edge or bottom, which will lead to the breakage of the exhaust glossy paper during printing, thus preventing normal production. Therefore, printing takes about 1 meter of material bonding. On the other hand, before long-term... less

For example, the height of common containers is about 2 meters. Or steel walls, not conducive to heat preservation and sound insulation; Then there is the appearance, the enclosed space is difficult to light ... but it is only because it has not been "carved" and only needs to be modified according to livable conditions. it can even replace the position of reinforced concrete in the current building.
Viscose fiber is the full name of viscose fiber. It is divided into viscose filament and viscose staple fiber. Viscose fiber viscose fiber-also known as rayon, ice silk, viscose filament.
