Skeleton Container Trailer is a kind of container transport semi trailer frame and another is flat type. The skeleton type driving is made by welding the longitudinal beam, the transverse beam and the front and rear beams. The longitudinal beams are welded into high-quality steel plate 16Mn submerged arc to form an I-shape (the main size is 450, 500). The beam has a welded rectangular cross-section. An integral long beam is provided at the position of the intermediate container locking device to improve the carrying capacity of the container locking device. The difference between the flat type and the skeleton type is that the flat type adds a frame and a pattern floor. The frame of the wood series container transport Semi Trailer is all shot blasted. The entire frame is assembled and welded on a special positioning platform. It has a reasonable structure, high strength and beautiful appearance. A container tightening device is installed on the frame, which can load two standard containers of 40 feet and 20 feet. The four container tightening devices at the front and rear ends are of a fixed structure, and the middle container tightening devices are of a concealable structure. When loading containers, the intermediate container locking device can be lowered below the cargo platform level as needed. Choose mechanical bearing device, mainly Baohua 12T, 20T; Fuhua 13T; JOST; and other types. Its function is to support the ground when the traction device is disengaged from the trailer and bear the front load of the semi trailer. There are two types of support devices: single-acting type and linkage type, which are mainly composed of supporting disc, screw drive mechanism, reduction box and joystick. Suspension devices include single-axis suspension and dual-axis suspension. Three-axis suspension. Semi trailers are equipped with two spare tire frames, which are installed on the left and right sides of the trailer frame, and are equipped with spare tire lifters.

The reporter learned from the Langfang City Productivity Promotion Center last week that the modified potassium ferrate production technology developed by the Chinese Academy of Sciences will be used for the first time in the production of modified potassium ferrate to make the production process of potassium ferrate become Easy to control. The stability of the product has been greatly improved, and the corrosiveness to metals has been greatly reduced, so it can be truly used as a new generation of green broad-spectrum disinfectants and water purifying agents.
For a long time, chlorine disinfectants have become the mainstream product of the disinfectant market with its excellent broad-spectrum disinfection effect, and the aluminum-based water-repellent agent has become a mainstream product in the water purification agent market because of its stable and reliable flocculation and turbidity-reducing effect. Recent studies have found that chlorine-containing organic compounds formed during the use of chlorine disinfectants have strong teratogenic, carcinogenic, and mutagenic effects, and long-term use of aluminum-based water purifying agents may cause senile dementia and other diseases. As a promising multi-functional green and efficient water treatment agent, ferrate has gradually attracted attention from the market.
However, due to the poor storage stability of potassium ferrate and the difficulties in production and preparation, the preparation of high-purity ferrate remains in the laboratory preparation stage so far, and industrial production has not yet been realized. The project completed by the Chinese Academy of Sciences for the first time used step-by-step doping technology to produce modified potassium ferrate, which inhibited the side reactions of potassium ferrate production process, greatly reduced the difficulty of industrial production, and significantly reduced the alkali consumption and increased the Separation efficiency eliminates the need for drying and dehydration of organic solvents, and significantly improves storage stability and safety.
According to experts, once the modified potassium ferrate green disinfectant achieves industrial production, it will have a large market in China. If the per capita annual amount of 0.1 kg is calculated, the national market capacity can reach 100,000 tons per year. According to an annual production capacity of 10,000 tons of modified potassium ferrate, the product is sold at a price of 30,000 yuan per ton. The annual sales will be 300 million yuan and the profits and taxes will reach 100 million yuan.
The test results show that the modified potassium ferrate can not only be used for the sanitation and disinfection of vegetables and fruits and the cleaning and disinfection of metal surfaces, but also used for disinfecting water purification of swimming pools, disinfection and epidemic prevention of aquaculture, and decolorization and reuse of printing and dyeing wastewater.
A new generation of green disinfectants is expected to appear in the market
