Solar energy generally refers to the radiant energy of sunlight, which is generally used to generate electricity in modern times. Solar power is an emerging renewable energy source. And in a broad sense, solar energy is also the source of many energies on the earth, such as wind energy, chemical energy, water potential energy and so on. Now solar energy is gradually being applied, such as the solar street lights and solar water heaters in the middle of the road that we see in daily life, and the new type of solar people are gradually using the field of automobiles.
In more developed cities, we can see a variety of street lights, street lights powered by wind energy, and solar street lights. In the case of shortage of global resources, solar energy is undoubtedly the endless resource that all humans dream of. It is already in sight, including going to space to collect solar energy, transmitting it to the earth, and turning it into electricity to solve the energy crisis facing mankind. The following is an introduction to the commonly used light poles used to support solar street lights:
The most commonly used solar street light is the steel cone light pole, which is characterized by beautiful, durable, strong, and easy to be made into various shapes, simple processing technology and high mechanical strength. The cross-sectional shapes of commonly used tapered light poles are round and hexagonal, and some also use octagonal shapes. The taper is mostly 1:90 and 1: 100. The wall thickness is generally selected according to the force of the pole. 3-5mm.
The working environment of the solar street lamp is outdoor, so the requirements for supporting the lamp post are better. To prevent the lamp post from rusting and corroding and reducing the structural strength, the lamp post should be treated for anti-corrosion. The anti-corrosion method is mainly to take some preventive measures against the cause of rust. Anti-corrosion should avoid or slow down the influence of humidity, oxidation, high temperature, chloride and other factors. Common methods are as follows:
1. Plastic spraying treatment: spray plastic treatment after hot-dip galvanizing. The plastic spraying powder should be selected for outdoor use, and the coating should not be peeled or cracked. Plastic spraying treatment can improve the anticorrosion performance of the steel rod, and greatly improve the aesthetic decoration of the lamp post, and the color can also have a variety of choices.
2. Hot-dip galvanizing: The process and method of immersing the pre-processed parts in the molten zinc solution to form a zinc and zinc-iron alloy coating on the surface. The thickness of the zinc layer is 65-90um. The zinc layer of the galvanized parts should be uniform, smooth, free of burrs, drippings, and excess agglomeration. The zinc layer should be firmly combined with the steel rod, and the zinc layer should not peel off or bulge.
In addition, the solar street lamp manufacturer introduced that since the solar street lamp pole is equipped with electrical components such as a controller (some batteries are also installed in the lamp pole), it is also necessary to pay attention to the waterproof and anti-theft performance of the lamp pole to prevent rain from entering the lamp pole and causing electrical Failure; the maintenance door can be opened by avoiding the use of conventional tools (such as hexagon socket bolts, pliers, etc.) to prevent theft or destruction by humans.
Yangzhou solar street lamp manufacturers mainly produce and sell: solar street lamp series, led street lamp series, high pole lamp series, Chinese lamp series, courtyard lamp series, lawn lamp series, various other special street lamp series, undertake road lighting projects, etc. ,

PTFE O-Ring
Polytetrafluoroethylene (PTFE) is a high molecular weight polymer, one of the most versatile plastic materials known and useful for a large range of products for applications excluded to other materials. Teflon o-rings are known for high heat resistance, high resistance to chemical agents and solvents, anti-adhesiveness, dielectric properties, low friction coefficient, and non-toxicity.
The tensile and compressive properties are to a large degree influenced by the working processes and the polymer used. PTFE, however, can be used continuously at temperatures up to 260°C (500°F), while possessing still a certain compressive plasticity at temperatures near to the absolute zero.
PTFE is a popular O-Ring material which is White in color. The PTFE O-Rings are popular for use in applications which require a chemically resistant and non-compressible material.
