Recently, the author learned from China's largest heavy-duty transmission company, Shaanxi Fast Gear Co., Ltd., that after the implementation of the new version of GB1589 last year, the company’s hydraulic retarder sales began to improve, especially after the start of the key remediation of highway trucks. Orders and shipments have increased substantially: In 2016, the cumulative sales reached 4977 units, an increase of 485% over the same period last year. In 2017, Fast's hydraulic retarder sales continued to improve. The cumulative sales volume in the first two months reached 1,218 units, which was a lot higher than the annual sales in 2015. New Deal Boosts Market Acceleration The implementation of the new version of GB1589 will undoubtedly play a significant role in boosting the opening of the hydraulic retarder market. The most obvious change is the explicit provision of the upper limit of heavy truck capacity, which will reduce the effective capacity of logistics vehicles by 10%. About 20%. To maintain certain operational benefits, in the current policy and regulations and the market environment, customers can control independently is trying to improve transport efficiency and reduce operating costs. The use of hydraulic retarders is an effective measure. Ordinary truck or tractor customers are currently avoiding the failure of long-distance braking by reducing the heat generated by frequent braking by adding water tanks to the brake drums. This does not increase the self-respect. Frequent showers of hot brake drums will also accelerate the aging and damage of the brake drums, causing safety hazards. Trucks carrying an average of 1 cubic meter of water together with water tanks including connecting parts, said less than a ton of weight. Under the current regulations, one ton of deadweight means that one ton of cargo is lost and one ton of benefit is lost. However, if the hydraulic retarder is installed, the situation will be very different. While ensuring the safe and stable downhill of the vehicle, it will not increase any fuel burden. It can also effectively reduce the wear of the main brake, extend the tire life, and reduce the maintenance and operating costs. . Especially for vehicles that have long-distance downhill sections in mountainous areas, the use of hydraulic retarders is more effective. Use of retarder improves vehicle efficiency Sichuan is one of the fastest-growing provinces in China in the past two years. The author learned from Zhu Yongbin, director of Shaanxi Fast Management Chengdu Office, that in the past one or two years, the company's retarder has achieved no success in the Sichuan market. Small breakthroughs last year reached 170 units through vehicle sales. In addition, 83 units of large customer-remodeled vehicles sold almost three times as much as in 2015. Zhu Yongbin said: “The improvement of customer safety awareness is the main reason. Of course, since the second half of last year, the implementation of GB1589-2016 and the strict control of Chaozhou have played a very good role in promoting the market.†He also said that this is also true. Thanks to Fast in recent years, the joint vehicle company has carried out a large number of customer experience marketing activities. At present, the local customers have become more aware of and more receptive to retarders. In addition, in the past few years, Fast has spared no effort in investing heavily in research and development. After continuous improvement, product performance has become more mature. Zhu Yongbin said that Fast has undergone extensive validation and actual vehicle testing. Under compliance loading, correct retarder constant-speed combined braking is used. A constant-speed downhill on a road above Grade 1 can be used to complete a single brake. Stepping on, so it is no longer necessary for customers to comply with the loading and transport of water tanks. Liu Minghui, brand manager of Sichuan Times Tiancheng Automobile Trading Co., Ltd., said that since the end of last year, Shaanxi Auto X3000 gold tractors with retarders have sold well. Today, on average, less than three vehicles in each hauled model have a retarder. Long-distance tractors equipped with retarders have become a popular configuration in the area. Liu Minghui also calculated an account for the author. Although the price of a full-auto slower refitted vehicle was nearly 20,000 yuan higher, the total weight of the vehicle could be reduced by 0.5 tons by reducing the weight of the vehicle without adding a water tank or reducing the water tank. According to the current general cargo road freight rate of 0.5 yuan/ton kilometer, if the average annual operation of 100,000 kilometers, then one year's freight will have an extra income of 25,000 yuan, more revenue will be able to recover the cost of retarder that year. If you add the cost savings caused by the replacement of brake pads, brake drums, and tires, at least over 40,000 yuan a year, the benefits will be considerable. This does not include the savings in the waiting time for adding water and the time savings that can be achieved with a safe, uniform descent after using the retarder. Retarder market has broad prospects At present, the hydraulic retarder is still in the initial stage of development in the domestic heavy-duty truck market. Last year, the total number of self-owned and foreign-funded brands actually sold more than 10,000 units, which only accounted for a very small portion of China’s total heavy-duty truck sales. However, the safety performance of the hydraulic retarder and high comprehensive benefits are gaining recognition from more and more customers. Domestic heavy-duty truck companies have long taken a look at this, and have increased the design and matching of hydraulic retarder models. If driven jointly by customers, manufacturers, car companies, and national authorities, the country will eventually form a very substantial market for hydraulic retarders. Assume that the match rate of China's heavy truck market retarder after 5 to 8 years can reach the level of half of developed countries and regions in Europe and America (ie, 30%), and that there will be more than 200,000 units (according to the current domestic heavy truck sales volume) market scale each year. .
Synthetic cryolite is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.95-3.01g/cm3, melting point about 1000°C, specific heat 1.056j/g°C at 18-100°C. It`s slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800°C will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.
Uses:
It`s mainly used as a flux in the aluminum smelting by fused-salt electrolysis; also an opalizer in the manufacture of enamel; an opacifier and auxiliary solvent of glass and enamel; an insecticide of crops; a flux in aluminum alloy casting; and in the production of ferrous alloy and effervescing steel; as well as a wear-resistant filler for Resin and rubber-boned Abrasive wheels.

New National Standard Brings Market Opportunity for Hydraulic Retarder Promotion
As an advanced vehicle-assisted brake device, hydraulic retarder is widely used in Europe and the United States and other developed countries and regions. In China, due to factors such as customer awareness and product cost, the promotion effect is not satisfactory. However, after the official implementation of the mandatory national standard “Outline size, axle load and quality limits for automobiles, trailers and car trains†(GB1589-2016) in the third quarter of last year, this situation is quietly changing.
