Ordinary lead-acid batteries, pay special attention to the usual cleaning work. Pay attention to check whether the pole and the chuck are tightly connected, if there is any corrosion and burning, and if the vent hole is blocked or not, and if the electrolyte is reduced, if it is found, it should be disposed of in time. When starting the car, the start time should not exceed 3 to 5 seconds, and the restart interval should be no less than 10 seconds. If the car is not used for a long time, the car should be fully charged. At the same time, the car will be launched once every other month and keep running at a medium speed for about 20 minutes. Otherwise, the placement time is too long and it will be difficult to start. General maintenance-free batteries should also be checked frequently, and problems should be replaced in time. Maintenance-free batteries are now available in most cars. These batteries do not require the addition of distilled water during use. The terminals do not corrode, have less self-discharge and have a long life. However, if it is not checked in time, the battery is not clear to the owner of the scrapping period, which will also affect the normal operation of the car.
In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects.
PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.
the Degree of polymerization of SG5 is 1000. usually we also call PVC Resin S1000. Its K-value is K67.

Improve lead acid battery life, cleaning and maintenance is the key
If the battery is not cleaned in time, it will easily affect the battery life and power supply. Simply put, a battery is an electrochemical device that converts chemical energy into electrical energy. Keeping the battery working properly, battery cleaning is essential. The oxidation reaction between the pole and the chuck of the battery is easy to occur, and the metal parts of the chuck portion can be severely rotted.
