Others don't know the mobile wagon driving skills!
Now the country’s economic situation is getting better and better, and driven by various industries, the number of people buying mobile sales vehicles is also increasing. The widening of the road has gradually increased the number of vehicles, and the daily violations of red lights, drunk driving, overtaking, and so on are also being performed every day. In fact, every driver knows all traffic laws and regulations. However, everyone's heart will have a fluke idea, and they will never learn a lesson if they don’t eat a bit of money. However, after an accident occurred while driving a mobile sales vehicle , it is impossible for any method to recover it.
After relevant experiments prove that when the vehicle encounters some sudden conditions during the driving process, it takes only 12 seconds to complete the braking situation. If you drive at a speed of 60 per hour, Km, then that still requires a buffer distance of two hundred meters, if the distance between the front and the rear when driving a vending truck is too close to one, if in the event of a sudden situation , there will be a rear-end accident. And now the number of motor vehicles in each city is relatively large, and it is not possible to have such a fast speed or space for you. Therefore, it can be said that the distance between cars can be shortened slightly, but it cannot be less than 50 meters.
A mobile vending truck driver can not step on the brakes in any situation because the driver will have a lot of inertia when he steps on the brakes, causing injuries to nearby personnel. If there are following vehicles behind, then it will lead to the rear vehicles have not had time to respond, there has been a rear-to-back incident. In fact, the most effective way is to be able to rely on the engine and the stalls to slow down the speed, so that it can reduce the mobile sales truck out of control. And the driver should not show off his technique of one-handed operation of the steering wheel to anybody. If there is an abrupt condition, the steering wheel will not be able to control the hands very well and will make a big mistake.
Borax is the basic raw material for preparing boron containing compounds. Almost all borides can be prepared by borax. They have important and wide applications in metallurgy, iron and steel, machinery, military industry, cutting tools, paper making, electronic tube, chemical industry, textile and other departments.
Glass and enamel industry
Borax in glass can enhance the transmittance of ultraviolet rays and improve the transparency and heat resistance of glass. In enamel products, it can make the enamel not easy to fall off and make it have luster. It is also widely used in special optical glass, glass fiber, non-ferrous metal welding agent, jewelry binder, printing and dyeing, washing (silk and wool), gold refining, cosmetics, pesticides, fertilizers, borax soaps, antiseptics, antifreeze and medical disinfectants.

Medical field
Borax is used for the treatment of skin mucosa, some tinea pedis, and also for the treatment of some inflammation, such as acute tonsillitis, pharyngitis, sore of mouth and tongue, gingivitis, otitis media, fungal vaginitis, cervical erosion, epilepsy, tumor, etc. It also has special effects in treating some animal diseases, such as chicken laryngotracheitis, goat infectious pustulosis, Mycoplasma suis pneumonia, and bovine chronic mucinous endometritis. Boron is an essential element for plant growth, human beings and animals.
Industrial field
In industry, borax is the most important industrial boron mineral. Borax is the most important compound of boron. Boron is often listed as a rare element in foreign countries, but there is abundant borax ore in China. Therefore, boron is not a rare element in China, but a high-yield element. In industry, borax is also used as a solid lubricant for metal wire drawing. It is often used as (inactive) flux to purify the metal surface in the welding maintenance of refrigerators, electric freezers, air conditioners and other refrigeration equipment. Remove the oxide on the metal surface; Add a certain proportion of sodium chloride to borax. Sodium fluoride, potassium chloride and other compounds can be used as active flux for welding between copper pipes and steel pipes and between steel pipes in refrigeration equipment.
