After going to the driving school to test the theory, the coach will begin to teach you some practical operations in the car, such as the actual operation of piling, moving warehouses, trails, grade parking, etc., and those most basic will be the driver's seat. The adjustment of the sitting position of the chair and the adjustment of the rear view mirror are the easiest to learn. However, after a long period of study and examination after driving school for a few months, it was out of the basic operation where the coach learned that he would not understand how some of the buttons in a commercial vehicle should be used. , I often see some female drivers on the road or the trunk is not closed, the engine lid is open, or the fuel tank lid is open, it was a cold sweat for her. So, what buttons in a commercial vehicle cannot be freely pressed? 1. The hood buttons of commercial vehicles are all set in the cockpit of the vehicle. However, there are some models with hood buttons that are not clearly identified, and some models even have the hood open. Afterwards, the relevant logo is also not visible in the dashboard. If you accidentally press the button to open the hood, stolen by a thief can be a bad battery. 2. Driving a commercial vehicle in the evening is the most frightening thing. Drivers who chaotically press headlights and mistakenly press the headlight button are low-level mistakes that a novice driver would commit. In order to better extend the service life of the lights, the old driver will generally turn off the manual switch. Now, in some small cities, the brightness of street lamps will be relatively good. Some drivers think that the lighting conditions are already so good. Driving lights does not have any effect, as others will see. Some people may think that it is so close to a distance of a dozen or twenty minutes. It does not matter if you do not drive. Such low-level mistakes, please do not easily commit, not only for yourself, but also for the safety of others. 3, after the button of the fuel tank cover of the commercial vehicle is invisibly pressed, it is also necessary to bear the case of the stolen oil thief stealing oil. Although it is somewhat difficult for a commercial vehicle to steal oil, it cannot be maintained. Some boring people lose something to the oil port, the consequences are unthinkable! Some commercial vehicles are still using the direction of opening the fuel tank cover in the car. In addition to fueling the fuel tank, it is best not to open it, or to randomly press it.

PVC sealing strip is a sealing product mainly made of polyvinyl chloride (PVC). The following is a detailed introduction:
1〠Material characteristics
Flexibility and Elasticity
PVC sealing strips have a certain degree of flexibility and can be easily bent to adapt to different shapes of sealing parts. At the same time, it also has good elastic recovery ability, which can quickly return to its original shape after being squeezed or stretched, ensuring the durability of the sealing effect.
Chemical resistance
Has good tolerance to many common chemicals. For example, in general acidic and alkaline environments, PVC sealing strips can maintain stable performance and are not easily corroded, which makes them suitable for use in environments that may come into contact with chemicals.
Economic viability
PVC is a relatively common and low-cost material. This gives PVC sealing strips a certain price advantage, which can meet the needs of large-scale production and widespread application, especially suitable for cost sensitive projects.
Color customization
Colors can be customized according to different needs. Whether it is to match the appearance of the product or to distinguish different functional areas through sealing, it can be easily achieved by adding pigments, providing more flexibility for product design.
2〠Product application
construction industry
Widely used in the sealing of building doors and windows. It can effectively prevent the infiltration of air, dust, and rainwater, and improve the insulation, thermal insulation, and sound insulation performance of buildings. For example, in the installation of windows in residential and commercial buildings, PVC sealing strips can fill the gaps between the window frame and the glass, reducing heat transfer and interference from external noise.
automotive industry
Used for sealing car doors, windows, luggage compartments, and other parts. It can prevent rainwater, dust, and air from entering the car, while also providing some shock absorption and sound insulation, improving the comfort and quietness of the car interior.
Electrical equipment
Plays a role in the enclosure sealing of some electrical devices, such as refrigerators, freezers, etc. It can maintain the sealing inside the equipment, prevent cold air leakage, and thus improve the energy efficiency of electrical appliances.
