Novice car need to pay attention to the four errors of car maintenance
In the maintenance of the car will inevitably lead to some misunderstandings, usually when the Internet, as much as possible to understand this information, remember the maintenance process and do not, will avoid detours. Keep your car healthy. Today Xiao Bian will introduce you to the maintenance of four points.
1. Do not apply oil to tire nuts Do not apply oil to wheel bolts and nuts. In the maintenance, a small number of private owners in order to prevent rust on the bolts and nuts on the wheels, the bolts and nuts are painted with ingenuity when they are installed. They do not know that this approach is not only wrong, but also brings certain hidden dangers to the driving safety. After bolts and nuts are tightened, they have self-locking characteristics. When the lubricant is applied, the self-locking coefficient between the two becomes smaller and the self-locking performance decreases. When the car is driving at a high speed, the bolts and nuts are easy to loosen or fall off, causing accidents and the consequences are unimaginable.
Second, car wash should pay attention not to wash the body with water. When the summer arrives, common private car owners wash their bodies with water while wiping them with rags. The private car owners are reminded that it is best not to flush water directly inside the car body. Because the underside of the floor rubber pad in the cab is not "a flat surface," the structural requirements make the underside of the cab floor pad have many recesses and through holes. After rinsing with water, it is either deposited in the groove and does not dry easily, or flows from the through hole to parts such as the gearbox to cause rust. In particular, cars with better sealing performance cannot wash the interior of the vehicle directly with water. The correct method is to wipe with a damp cloth, avoid direct water rinse.
Third, the addition of coolant Do not mix the use of different brands of coolant. We all know that engine coolant should be added in time, but do you mix different brands of coolant together? If so, advise you to release the coolant as soon as possible and re-add the same brand of coolant. Because different brands of coolants may have very different chemical properties, such as effective preservatives for ferrous metals, they are often corrosive to aluminum products, while preservatives for aluminum alloys are harmful to ferroalloys. Because different brands of coolants use different preservatives, they cannot be mixed.
Fourth, when starting up, it is necessary to pay attention to the throttle when the EFI car starts. It is a habit of many old drivers to pedal a few feet before starting the engine, especially during winter cold start. However, this starting method does not apply to EFI cars.
The engine equipped with an electronically controlled fuel injection device is different from an ordinary carburetor type engine. Its fuel injection control device can automatically adjust the fuel supply according to the temperature and operating conditions of the engine so that the engine can be started smoothly, that is, when the cold car starts. The fuel injection control device can automatically increase the fuel supply. Therefore, when the engine of the EFI sedan is started, there is no need to step on the accelerator, and it is even more urgent not to step on the engine before starting the engine. Otherwise, the engine start is not good.
Chlorinated Polymer For Paint & Coating
Chlorinated Rubber , High Chlorinated Polyethylene ,Chlorinated PolyPropylene
a synthetic polymer; a chlorinated product of polyethylene or polypropylene or elastomer. Polyethylene and polypropylene products containing 50–70 percent chlorine are used as binders in paints and varnishes and as bases for various adhesives and coatings.
Among the valuable properties of all chlorinated polyolefins are good adhesion to various surfaces and resistance to fire.
Chlorinated polyethylene products are also resistant to the action of ozone, oxygen, alkalies, saline solutions, strong acids,
aliphatic hydrocarbons, alcohols, oils, and gasoline; they are somewhat less resistant to chlorinated aromatic hydrocarbons.
