The difference between domestic tires and imported tires is mainly in material processing, theoretical data and practical experience. Compared with imported brand tires, domestic tires have the upper hand.

1. Comparison of raw materials and processing technology

Imported tires are not necessarily made abroad, and imported brand tires may also be made in China.

The raw materials are the same, and China has other advantages. China is close to the rubber producing area, and the quality of raw materials is more advantageous.

the raw material of the tire is rubber. At present, the main rubber producing countries are Thailand, Indonesia, Malaysia, China, India, Viet Nam, Myanmar and Sri Lanka. These countries are mainly distributed in Asia and Southeast Asia. Tires produced in the United States and Europe need to import rubber from Asia and Southeast Asia.

II. Comparison of theoretical indicators

Compared with the strength of tire cord, the strength of domestic tire cord is excellent.

compared with the pressure resistance of tires, the pressure resistance of domestic tires is better.

compared with tire thickness and structure, domestic tire thickness and structure are more suitable for national conditions.

Third, compared with the actual test, the braking distance of domestic tires is shorter.

the tire noise experience test shows that the tire noise data of domestic tires are average, but the experience is not much different.

quality control level, domestic tire quality control ability is also at the advanced level in the world.

2. Is Sri Lanka safe now?

Sri Lankans are very friendly to China people. The local government did not move, and the Embassy of China made unified arrangements. Life is still safe. But you must leave the country safely. Ordinary Sri Lankan people are friendly to China people, while Buddhists in the south have always been wary of India. Tamils in the north are pro-Indian, but a few years ago, China helped the southern government defeat the Tamil Tigers in the north in the civil war.

3. Is Sri Lanka good

As can be seen from the map, Sri Lanka has an excellent geographical position, with the Straits of Malacca on one side and the Persian Gulf and the Gulf of Aden on the other. It is the busiest maritime trade route in the world, which is very beneficial to economic development. Sri Lanka Garden is called the crossroads of the East China Sea because of its unique geographical location.

Sri Lanka is located in the north-central Indian Ocean, with Malacca Strait on one side and Persian Gulf and Gulf of Aden on the other. It is the only way for East-West maritime transportation, and its strategic position is very important.

As far as natural conditions are concerned, Sri Lanka is really a treasure island. The island is high in the middle and low on all sides, with fertile land and abundant water resources. In addition, it is located in the tropics with abundant rainfall, so all kinds of products are quite rich.

Sri Lanka is not only one of the three largest tea producers in the world, but also one of the five largest gem producers in the world. Three-fifths of the island's underground is distributed with various gem veins. Sapphire, ruby, tourmaline and other precious stones here are not only rich in variety, but also have huge reserves.

4. Is Sri Lanka safe?

Sri Lanka's current crisis is related to many factors at home and abroad.

from the internal factors, after taking office in 219, Rajapaksa of Gotabaya began to implement tax reduction policy, which led to the reduction of government revenue and weakened the ability to cope with the crisis. Sri Lanka The American government printed more money to repay domestic loans and foreign bonds, which accelerated inflation.

Some experts also believe that China's problems can be attributed to the fact that its foreign exchange reserves have actually dried up.

since the end of the civil war in Sri Lanka in 29, the country has chosen to pay more attention to the domestic market rather than selling to foreign markets. Therefore, while the export income is still low, the import expenditure is increasing.

At the beginning of p>221, when the lack of money became a serious problem in Sri Lanka, the government tried to stop the outflow of foreign exchange, banned the import of all chemical fertilizers, and let farmers use organic fertilizers, resulting in a large-scale crop failure. Sri Lanka had to replenish its grain reserves from abroad, which made its foreign exchange shortage more serious.

5. Is Sri Lanka national security

Let's put it this way. If natural and man-made disasters come, you can not escape. After all, this is a country at war. If you go out, you will be accompanied by bodyguards, which is relatively safe, but there are many car bombs and the like.

6. Introduction to Sri Lanka
