Lead Based Compound Stabilizer For PVC Window Profile PVC window profiles are a common building material that has excellent weather resistance, corrosion resistance, and thermal insulation performance, making them widely used in the construction industry. However, PVC materials are prone to aging and deterioration during processing and use, which affects their service life and performance. In order to solve this problem, a special stabilizer - lead based composite stabilizer has been developed. Lead based composite stabilizer is an important material that can improve the thermal stability, light stability, and antioxidant performance of PVC window profiles, and extend their service life. In the construction industry, the application of lead based composite stabilizers will further promote the development and application of PVC window profiles. building materials,PVC additives,PVC window profile additive Hebei Xiongfa New materials Technology Development Co.,LTD , https://www.xiongfa-tech.com
It is like a Transformer, sometimes split into two Luxor 3200 tons, and sometimes "evolved" into a 136-meter-high giant, a body will lift 6400 tons of weight to 120 meters high. This is a 6400-ton hydraulic compound crane jointly developed by Sinochem Construction Group, Taizhong Group and Zhongke Synthetic Oil. On July 12, the device successfully performed a double-lift experiment and successfully passed user acceptance.
Compared with the large crawler cranes that are often used in the past, the outstanding features of this equipment are the largest lifting weight in the world and the highest lifting height in the world. Its maximum lifting weight is 6,400 tons, which is equivalent to the weight of 100 full-load train skins. In addition, it also has a combination of flexible conditions that can be used independently and disassembled. The original dual-stage design has obvious advantages in the overall lifting. In the process of disassembling and assembling the equipment, more than 300 chords and more than 1,680 web members can be assembled at any time, which greatly facilitates on-site assembly and improves construction efficiency. The whole machine can be divided into two working conditions of single and double doors. Each working condition can have different combinations of spans and heights.
At present, the rapid development of the petrochemical industry and the coal-to-oil industry has increased the demand for large-tonnage cranes. The superlifting capacity of the 6400-ton hydraulic demrick cranes can meet the lifting production requirements of large-scale containers in the next 5 to 10 years by Sinochem Erjian Construction Group, and it has become the strongest lifting capacity in the industry.
During the development of the equipment, Taizhong Heavy Industries Group adopted new technologies and new processes such as synchronous control technology of gantry lift-up and 16 main lifter synchronous control technologies. At present, four patents have been authorized.
