Over the past few days, many provinces in southern China have been hit by heavy rain, and the disaster in some areas has been very serious. Rainfall and the resulting water in the road area will bring safety hazards to traffic and even the vehicle itself. According to reports, in a heavy rain in mid-June alone, there were more than 3,000 flooded vehicles in Shenzhen City, with severe losses. The weekly weather forecast of the Meteorological Observatory of our province also shows that there is a lot of precipitation in our province this week. Except for Sunday, there will be rainfall almost every day in the Central Plains, especially in the southern region. So, in the face of the rainy season, how can we ensure safe driving?

Although the rain in the previous two days was not heavy, it also made many car owners feel inconvenient to drive in the rain. During the rainy season, vehicles are more prone to failure, and traffic accidents are also common. Therefore, driving in the rainy season is not only a test for the driver but also a test for the vehicle. In order to be "prepared".

Manually check the wiper

During heavy rain, what appears in front of the driver is white. If the wiper's sweeping ability is severely reduced, it will directly affect driving safety. Therefore, wipers are naturally very important in ensuring driving safety on rainy days.

"When driving in the rain, there is no clear rain, which will make the field of vision extremely blurred, which often leads to traffic accidents. The increase in rain will inevitably make the wiper more responsible, so its inspection and maintenance must be more careful. "Master Zhang of a maintenance service station told reporters that in the rainy season, the owner must first check the wipers. Inspection method: The owner can set the wiper switch at various speeds by himself, pay attention to whether the wiper has vibration and abnormal noise in the work, check whether the wiper maintains a certain speed at different speeds, and observe the state of the wiper and the wiper Whether the support rod has uneven swing or leakage.

Keep the tire pressure high

"To prevent the car from skidding on rainy days, the tire inspection cannot be ignored." Princeton tire experts said that the tire pattern should be replaced in time, because when the tire wears to a certain degree, the grip will be reduced, and the corresponding braking distance will be extended. The chance of slipping increases. In addition, in order to prevent the car from slipping while driving, the tire pressure of the tire should be checked, and it is best to maintain a high tire pressure. Because the vehicle brakes in the rain, it needs to have enough force to drain the rain between the tire and the road, so that the vehicle can stop smoothly. On the contrary, if there is not enough power to drain the rain between the tires and the road, the car cannot be stopped in the shortest time.

Inspection method: The owner of the tread can check it by himself. Generally, the tire side of the factory tires is marked with a wear limit. The owner can use this to observe the actual wear of the tire. As for the tire pressure check, you need to check it in a professional store.

Pay attention to the sealing of the vehicle

"The problem that is easy to appear in summer rainy days is that the water in the car causes the short circuit of the line." Master Zhang said that the vehicle has a rubber sealing strip on the door frame part. On the one hand, it guarantees the sound insulation of the vehicle, and on the other hand, it The tightness of the car. Old vehicles need special attention in terms of vehicle tightness. Check and clean the rubber seals on the doors, bottom drain holes and chassis. If the drain holes are clogged or the rubber seals are not well sealed, it will be necessary when driving on rainy days or passing through waterlogged roads. It is easy to cause water in the car. In severe cases, it will cause a short circuit in the car's power cord and damage to the vehicle controller.

Inspection method: The owner can observe through the surface. If it is found that the sealing strip has cracked and has no elasticity, then it is best to go to the 4S shop and ask a professional to check it. If it is no longer usable, it must be replaced in time.

 Our sodium chlorite is used in textile industries also, and sodium bisulfate is a by-product. On the other hand, we provide formulated products used in bleaching, dying, etc. For example, ammonium persulfate, Potassium Persulfate and Sodium Persulfate.

1. ammonium persulfate
Application: Ammonium persulfate is a strong oxidizing agent and can be found in a wide variety of industrial and consumer uses. It appears as a white crystalline powder but may be formulated into cream preparations.
♦  disinfectants and bleaches
♦  bleaching agent for hair colourant and lightener formulations
♦  bleaching and strengthening agent for flour in the baking industry

2. potassium persulfate

This salt is used to initiate polymerziation of various alkenes leading to commercially important polymers such as styrene-butadiene rubber andpolytetrafluoroethylene and related materials.

It is used in organic chemistry as an oxidizing agent, for instance in the Elbs persulfate oxidation of phenols.

As a strong bleaching agent, it is used in hair dye substances as whitening agent with hydrogen peroxide.

It is a Food Additive.

3. sodium persulfate
(1) Used in cleaning and picking of metal surface.
(2) Used in accelerated curing of low formaldehyde adhesives.
(3) Used in modification of starch , production of binders and coating materials.
(4) Desizing agent and bleach activer.
(5) An essential component of bleaching formulations for hair cosmetics.
