Winter car battery maintenance method

Many people in winter driving often have such feelings: just full of storage batteries, no electricity soon. Feeling that the electric image in the battery was stolen, it was a headache for many owners. This is due to the low temperature in winter and the battery capacity at low temperature is much lower than that at normal temperature. Therefore, in the winter, it is very important to maintain the battery. In the following, the first car network will introduce you to the winter car battery maintenance.

Why is the battery dead?

After the vehicle stalls, there are functions and components running

Many owners think that after the switch is closed, the car is in a state of power failure. In fact, many devices are still in operation. The most common is the anti-theft system installed on many models. As long as the car locks the door, the system will begin to work. The amount of electricity it consumes is much smaller than that of a headlight. However, in a few weeks, when the car is not started for a long time to charge and the state of battery storage is poor, the battery will run out.

After the flameout, is the car completely static? In the traditional impression, as long as the car key is screwed to the closed state of the switch, all the parts of the car are stopped. However, if the engine temperature is too high, even if the car is in the off state, the vehicle key will be pulled out of the car, and the cooling system will automatically start to cool the engine system. Only when the engine system temperature drops, the cooling system will automatically stop working, usually this process is 3 to 5 minutes.

I forgot to turn off the lights after I locked the car

No lights were parked, overnight, and the battery was overworked and shocked and finally went on strike. Of course, there are many vehicles that already have automatic lock lights off the car, but there are still some cars that need to manually turn off the headlights, so pay extra attention.

What are the precautions for using the battery in winter?

1. When the battery is not used for a long time, it will slowly discharge itself until it is scrapped. Therefore, a car should be started at regular intervals to charge the battery.

2. Avoid parking the car in an open parking lot for a long time. If it is parked for a long time, remove the battery and take it away to prevent icing damage.

3. The storage capacity of the battery can be reflected on the dashboard. When the current meter pointer indicates insufficient power, charge it in time.

4. The car engine is not easy to start in the winter. The time for starting each car should not exceed 5 seconds, and the interval for starting again should not be less than 15 seconds.

5. Distilled water or special rehydration solution should be added to the deficit electrolyte. Avoid pure drinking water instead. Because pure water contains many trace elements, it will cause adverse effects on the battery.

6. Clean the terminals of the battery at intervals and apply special grease to protect the wiring harness. Always check the accessories and connection lines on the battery.

7. Daily driving should always check the small hole on the battery cover is vented, if the battery cover hole is blocked, the resulting hydrogen and oxygen can not be discharged, the electrolyte expansion, the battery casing will burst, affecting the battery life.

8. It is forbidden to use automotive electrical equipment after the vehicle is turned off. If the engine uses the battery alone without generating electricity, it will cause damage.

9. Check whether there is any place of aging or short circuit in each part of the circuit to prevent early retiring of the battery due to excessive discharge.

10. Generally speaking, the battery life of a car is about 2 to 3 years, but the refitted car equipment tends to degrade the life of the battery. In winter, it is often necessary to check whether the battery is operating normally.

How to maintain the battery:

1. Wipe the outside of the battery with a damp cloth to clean the panel, the dust on the column head, oil, white powder, etc. The stigma of the battery is often scrubbed. Not only will the white etched powder not accumulate on the top of the battery, but the battery life will be longer than expected.

2. Open the battery water cap to see if the water level is in the normal position. Generally there are upper and lower markings on the side of the battery for your reference. If it is found that the water level is lower than the subscript line, distilled water must be added. The water cannot be added too much. The standard is the middle of the upper and lower marking lines.

Starch Glue For Paper Core

The special starch glue for paper core is a starch adhesive made by oxidation of corn starch. It is nontoxic, tasteless, formaldehyde free, easy to operate and convenient to transport.

Product features:

1. High adhesive strength, low adhesive consumption, fast drying, no delamination.

2. Use our glue to make paper tube with good hardness, no brittleness, no bubble, no

crack.

3. The viscosity is stable and has good flexibility, water and moisture resist ance.

4. The ratio of powder and water is 1:2-1:3, and the cost is only 50% of the white emulsion.

Scope of application:

1. Suitable for spiral paper tube mechanical equipment.

2. It can be used for adhesive production of paper barrel, paper corner protector and

paper core.

Materials :glue powder,caustic soda,Borax

1.add 25kg water(normal tempreture) into the blender,

2.Then add the glue powder(25kg),and stirring it for 5 minutes to dissolve fully.

3.Take another container,add 10kg of water,will be caustic soda, borax pour into the water,stir well,dissolve fully.

4.The caustic soda and borax solution put into the glue powder solution slowly,stirring evenly,dissolve fully,the can be used after wait 15 minutes.

Storage considerations:

1.Storage a few days later will be a normal phenomenon of precipitation,you just need stir it again.

2.In the process of storage need to cover seal,because the colloid moisture will volatilize,sometimes the glue powder solution will become solid or Like jelly,at this time ,you can ease with a small amount of water of 0.5-1 kg of caustic soda.
