The car's headlights are just like human eyes and are an important part of it. With the prevalence of the term “refitting†and the fact that people nowadays like to highlight personalization, it led to the prevalence of refitting of headlights. Many people change the color of the lights to other colors than the original ones, such as blue and green. What problems should we pay attention to when modifying the lights?
1, for the brightness of the lights to be moderate, not the brighter the better. Although brightening the lights can attract more attention, it will also cause many unnecessary dangers under the stimulation of strong light. If the headlights are too bright, it will cause visual disturbances to people on the road when traveling on the road, which may cause accidents.
2. The lighting color of some positions of the lamp can not be changed arbitrarily, for example, the color conversion of the near and near lights must be modified according to the regulations, otherwise it will not only affect the vehicle inspection and insurance, but also may cause the occurrence of traffic accidents. .
3. For the location of the original lighting, we also can not freely mobilize, such as the width of lights, etc., and after the installation of decorative lights also need to avoid too close to the location of the original lights, resulting in interference, the location can not Too high, so as not to affect the sight of the opposite vehicle.
4. It is not advisable to carry out a single xenon lamp modification. If you want to improve the car's lighting system, we recommend using an upgraded halogen bulb or a brand-name brand of xenon headlamps with a guaranteed quality. Due to the good lighting effect of xenon headlamps, many owners prefer to convert the headlights into xenon headlamps. However, conversion into Xenon headlamps without permission is not only illegal in foreign countries, but it will also be difficult to pass the annual inspection of automobiles in China. Because of the high lighting intensity of the xenon lamp, the scattering of high-intensity light will stimulate the driver's line of sight to the opposite side, but it will easily cause traffic accidents. Therefore, foreign countries require vehicles equipped with xenon lamps to also be equipped with a set of lens systems to allow vehicles to The light range is more concentrated.
The above is about some considerations for the modification of automobile headlights. I hope that those who love to refit car headlights can play a vigilant role in helping us to better modify the headlights of cars, so as to avoid doing any useless work, which is time consuming. It broke again.
There are many kinds of pneumatic pipes, which are generally produced with PU raw materials, with stable quality, high pressure resistance, weather resistance, wear resistance, zigzag resistance, smooth and flexible pipe body, bright color, high elasticity, winding resistance and small bending radius.
The tube body is smooth and flexible, bright color, high elasticity, winding resistance and small bending radius. Temperature range: - 15 - + 70 ℃.
Product classification
1. Pu pneumatic pipe
2. Pu (polyether) pneumatic pipe
3. Pu (polyurethane) bobbin
4. Pu (polyether) bobbin
difference:
Polyurethane pneumatic pipe is over air type. If it is used for over water, its service life will be affected,
Polyether pneumatic pipe can pass air or water, with more stable physical properties and longer normal service life. It is an ideal material for pneumatic pipe.
The bobbin is wrapped with a layer of fiber in the middle of the common pneumatic pipe. Therefore, the bobbin is more solid, pressure resistant and non explosive than the common pneumatic pipe.
Product selection
What should be considered when choosing the type of plastics for blow molding pneumatic pipe?
The following aspects should be considered in the selection of pneumatic pipe materials.
Whether the wall thickness of the welded blank of the pneumatic pipe can be kept uniform, whether a higher blowing pressure is needed, whether the blowing is uniform, whether the surface of the pneumatic pipe is bright, whether the demoulding is easy, and whether the strength can meet the requirements, etc.
Performance comparison of plastics for blow molding pneumatic pipe. The pneumatic tube formed by blow molding is in thermoelastic state, and its density is smaller than that after cooling and shaping, resulting in shrinkage. For the general size of pneumatic pipe is not strict, forming shrinkage has little effect. But for the pneumatic pipes of specified size, such as some hoses used in precision machines, large shrinkage has a considerable impact. The larger the blowing volume is, the more significant the effect is.
The advantages of extruding and blowing plastic forming pneumatic pipe are less investment in production equipment, simple equipment structure, easy mold manufacturing, high forming of pneumatic pipe during production, uniform temperature control, and various specifications of pneumatic pipe can be formed. The disadvantage is that the wall thickness uniformity of pneumatic pipe is poor.
The advantages of injection blow molding pneumatic pipe are that the plastic pneumatic pipe has good product quality, accurate dimensions, no seams, uniform wall thickness, multi-mode molding production, high degree of automation, which is very suitable for large-scale high-efficiency production of small specifications. The disadvantage is that the investment of equipment and molding die is large, and the operation and production need skilled workers.

Tips for pneumatic pipe
Polyurethane pneumatic hose is suitable for compressed air, ordinary industrial water and non corrosive oil. In order to maintain a long service life, it must be used under rated working pressure and ambient temperature. As the temperature rises, the working pressure should be reduced accordingly. If it exceeds the limit, the hose may break. If the fluid temperature is too high or the fluid is corrosive, the hose may break. If the working environment temperature is too high or there is chemical gas in the working space, the hose may crack. If the hose is stored in a wet place or the storage period is too long, the hose may hydrolyze or age, which may lead to fracture
