First, when the specifications and models of the parts are unclear, it is necessary to look at the vehicle's certificate of conformity, operating instructions, engine certification, etc. There is also a look at the nameplate of the car, the nameplate of the engine, the model of the vehicle, the date of manufacture, and the serial number of the factory. Choose the same model to buy. Here, it is reminded that the accessories of similar models produced by the same factory are not necessarily common.
Second, when buying accessories, you should try to use the scientific name or some of the titles we can understand. Some purchasers often name car accessories in a random manner and do not use standard accessory names. Therefore, they will buy the wrong materials. For example, some users have 6 forward gears, and 1 reverse gear produced by FAW is called a 7-speed transmission. In the forward gear, a reverse gear transmission is called a 6-speed transmission. If they demand to purchase the first axle on a 6-speed transmission (actually wants to buy the CA1091 gasoline vehicle transmission with 5 forward gears), some dealers will sell it to the first axle of the CA1092 diesel transmission (with 6 forward gears). If the material officer does not recognize these accessories, it is easy to buy.
Third, the purchase of auto parts to the reputation, services, and other accessories to better the distribution unit to buy, like the purchase of the same car as the choice of businesses. You can't buy his accessories because you have a good relationship with the dealer.
Fourth, to buy auto parts, you must be familiar with and master the brand name, recognize the brand name. In the past, it was rated as the best product of the province and the honor period was 5 years. We should pay attention to mastering the good information and purchase the latest famous accessories. Here's a look at some of the user's misconceptions about the factory. In the past, most of the supporting plants were located close to the host plant or in the region. The state provided guarantees for the supporting plants in terms of technology, capital, equipment, etc., enabling the supporting plants to produce accessories that meet the OEM requirements. Many OEMs are now domestically or internationally-supported companies. Only companies that pass the inspection and approval of the product quality system of the OEM can obtain the right of a certain product. It must be clear about this aspect.
Precipitated Calcium Carbonate
Uses: Can be used as filler in rubber, plastics, paper, paint and ink industries. Widely used in organic synthesis, metallurgy, glass and asbestos production. It can also be used as a medium seeding agent for industrial waste water, a antacid for stomach and duodenal ulcers, a detoxifying agent for acidosis, a SOâ‚‚ eliminating agent in SOâ‚‚-containing exhaust gas, a dairy cattle feed additive and an anti-sticking agent for oil felt . It can also be used as a raw material for tooth powder, toothpaste and other cosmetics.
Usually used as a filler, widely used in daily chemical industries such as artificial floor tiles, rubber, plastics, papermaking, coatings, paints, inks, cables, construction supplies, food, medicine, textiles, feed, toothpaste, etc., as a filler to increase products The volume is reduced, and the production cost is reduced.
Light Calcium Carbonate is made of limestone, and can be used in daily chemical products such as tooth powder, toothpaste, cosmetics, etc. It can also be used in organic synthesis, metallurgy, glass and asbestos production.
The particle size of light calcium is smaller than that of Heavy Calcium Carbonate, the oil absorption is larger than that of heavy calcium carbonate, and the price is higher than that of heavy calcium carbonate. They are all commonly used fillers in latex paint, and they are best used together. Light calcium is better in terms of sedimentation, but its oil absorption is greater than that of heavy calcium, and the price is generally more expensive than heavy calcium. Although it is not as stable as heavy calcium, it is stable. Even for exterior wall paint, its application amount is also very large. of.
