Brake fluid is divided into four main categories: DOT3, DOT4, DOT5 and DOT5.1. The common categories on the market are mainly Brake fluid DOT 3, Brake fluid DOT 4 and Brake fluid DOT 5.1. Brake fluid, also known as brake oil, is an indispensable part of the braking system and is the liquid medium that transmits braking pressure in the hydraulic braking system.
It is very important to replace the brake fluid regularly, which can effectively reduce the situation that the brake fluid absorbs too much water and is more prone to air lock.

The sapphire substrate for LED lighting accounts for more than 90% of the sapphire substrate. From the current sapphire application structure, about 80 applications are currently applied to sapphire substrates, and about 20 are applied to non-substrate materials. Among them, sapphire is mainly used for LED illumination and SOS related products, and substrate materials for LEDs account for 90%. Above, LEDs have the most direct and most important impact on the demand for sapphire substrates.
The demand for LEDs has rebounded, driving demand for sapphire upwards. In 2012, due to the economic downturn, the demand for LED lighting was not as good as expected, resulting in a sharp decline in the utilization rate of upstream MOCVD equipment. According to relevant agencies, the global MOCVD equipment utilization rate in 2012 was only 59, and only 42 in mainland China, leading to sapphire. Substrate demand growth was significantly lower than expected. At the same time, due to the continuous release of new production capacity of sapphire, the relationship between supply and demand continued to deteriorate, the supply ratio of demand was only 66, and the price of sapphire fell all the way. In 2013, with the accelerated penetration of LED backlights, the demand for LED lighting increased significantly, stimulating the use of MOCVD equipment. The rate has increased to 74 (63 in mainland China), driving the demand for sapphire substrates to pick up, the demand supply ratio has gradually improved, and the demand has increased from the demand of 57.13 million pieces per year in 2012 to 83 million pieces per year (equivalent to 2 inches). Calculated), the demand-to-supply ratio is 80, which is the main driving reason for the rebound in sapphire prices.
Demand for LEDs continued to increase in 2014, and demand for sapphire is expected to continue to rise. Looking forward to 2014, LED lighting products continue to cut prices, and some product prices have been comparable to energy-saving lamps, stimulating the demand for LED lighting to accelerate upwards. At the same time, in terms of policies, the global ban on incandescent lamps was introduced in 2014, and new standards in the EU, Japan and other regions have been with 2013. H1 implementation, other relevant standards are expected to be introduced around the end of the year, will further promote the penetration of LED lighting demand, is expected to continue to drive demand for sapphire substrate materials to pick up. We expect the supply ratio of sapphire demand to further increase to 91 in 2014, and the supply-demand relationship is expected to improve significantly.
Iphone mobile app or open the new application of sapphire. If 2014 new varieties use sapphire to protect the screen, it is assumed that the sales volume will be 40 million and 120 million in 2014-2015, which will increase the demand for sapphire by 97.14 million pieces per year, and 291.42 million pieces per year (equivalent to 2 inches). Calculated), 2014 is almost equivalent to the number of integrated sapphire substrates for LEDs. In 2015, it will be twice the demand for sapphire substrates for LEDs. According to this calculation, the scale of sapphire market is expected to grow more than five times.
Normally, the replacement cycle of brake fluid is 2-3 years (40,000-60,000 kilometers), but in actual use, we still need to conduct regular inspections according to the use environment and the recommended information in the maintenance manual to check whether the brake fluid is oxidized or deteriorated. Wait, most 4S stores will check the brake fluid when we perform maintenance, and consumers only need to perform regular vehicle maintenance.
