Safe driving skills and experience are very important. Today we introduce some safety tips when driving on the highway.
Be cautious when driving at night.
The high-speed driving night uses high-beam lights to observe whether the taillights of the vehicles in front are bright. The owner himself can not drive the car with fatigue. If he feels sleepy, he must go to rest. The service area and the next road are good choices. . If a sudden fog rises above the expressway at night to obscure the line of sight, slowing down the speed of the car is the first choice. The double flash light turns on and looks at the line in the overtaking lane or the white sub-lane on the road surface. Always beware of a malfunctioning vehicle in the right lane. If you are near the service station, you must go and wait until the fog has dispersed a little before you start driving.
Pay attention to warning signs when parking
Highway driving is most afraid of parking, if you need to stop and check on the high speed because of the fault, you must open the right turn ahead to leave the road, park the car in an emergency parking place, it is strictly prohibited in the lane above the random parking, parking Open the double flash light of the warning on the car. The warning sign in the car should stand 150 meters away from the car to remind other cars. If there is a problem with the tunnel, as long as the car can still move, try to open the tunnel, the parking inside the tunnel is too dangerous. It is not possible to illegally drag a car with a steel wire hanging on the other car to the service site. This is a violation of the rules and poses a danger to others. It should be handled by an emergency telephone call.
Car puncture should be properly handled
It is very serious for families to burst their tires at high speeds, especially if the tires in the front row are punctured. The seriousness of the consequences is even heavier than that of trucks. Although we cannot predict the bursting, we must hold the steering wheel if the tire bursts. Correcting the car's efforts to maintain it will not correct the excess. Instead, it will lose control of the car and slowly decelerate to maintain the previous track. It must not step on the emergency brake and hit the steering wheel.
The above is the introduction of car safety driving skills to the owners, hoping to provide helpful help to everyone.
PVC Resin
PVC Resin is easy to process, and can be processed by molding, lamination, injection molding, extrusion, calendering, blow molding and other hollow methods. Polyvinyl chloride is mainly used to produce artificial leather, film, wire sheath and other plastic soft products, but also can produce plates, doors and windows, pipes and valves and other plastic hard products.
PVC Resin usually inculde carbide based and ethylene based. K66-K68 PVC RESIN, K59-K55 PVC RESIN, K71-K73 PVC RESIN. PVC RESIN SG5, PVC RESIN SG3, PVC RESIN SG8.
According to the different application scope, PVC can be divided into: general-purpose PVC resin, high polymerization degree PVC resin, and cross-linked PVC resin. General-purpose PVC resin is formed by the polymerization of vinyl chloride monomer under the action of initiator; high degree of polymerization PVC resin refers to the resin polymerized by adding chain extender to the vinyl chloride monomer polymerization system; cross-linked PVC resin is A resin polymerized by adding a crosslinking agent containing diene and polyene to the vinyl chloride monomer polymerization system.
According to the method of obtaining vinyl chloride monomer, it can be divided into Calcium Carbide method, ethylene method and imported (EDC, VCM) monomer method (the ethylene method and imported monomer method are commonly referred to as ethylene method).
According to the polymerization method, polyvinyl chloride can be divided into four categories: suspension polyvinyl chloride, emulsion polyvinyl chloride, bulk polyvinyl chloride, and solution polyvinyl chloride. Suspension process polyvinyl chloride is the largest variety in output, accounting for about 80% of the total output of PVC. Suspension method PVC is divided into six models according to absolute viscosity: XS-1, XS-2--XS-6; XJ-1, XJ-2--, XJ-6. The meaning of each letter in the model: X-suspension method; S-loose type; J-compact type.
