According to reports, the design of the shape structure of TC40 and TC57 series excavators is synchronized with the international, and the internationally renowned brand engines and hydraulic components are selected. In the same level of small excavator, it has the characteristics of large digging force, fast working speed, high performance, flexible operation, etc. At the same time, the original cooling heat balance exchange system makes the machine water temperature in the high temperature and harsh environment and high load operation state. The oil temperature can be controlled within the standard range.
The TC40 and TC57 series of small hydraulic excavators have many functions such as excavation, crushing, drilling, and gripping. Advanced product design, simple operation and reliable performance. Widely used in small earth and stone works, municipal construction, road repair, concrete crushing, buried cables, laying of tap water pipes, garden cultivation and river dredging. It has many functions of medium-sized excavator, and has the advantages of convenient transportation, energy saving, flexible operation, strong adaptability, etc., high cost performance, convenient maintenance and so on.
In terms of building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, and fibers, PVC was the world`s largest production of general-purpose plastics, and its applications are very widely. Widely used in all aspects.
PVC is a white powder with an amorphous structure. The degree of branching is relatively small. The relative density is about 1.4. The glass transition temperature is 77~90°C. It begins to decompose at about 170°C. It has poor stability to light and heat. After prolonged exposure to sunlight, it will decompose to produce hydrogen chloride, and further automatically catalyze the decomposition, causing discoloration, and the physical and mechanical properties also rapidly decline. In actual applications, stabilizers must be added to improve the stability of heat and light.
the Degree of polymerization of SG5 is 1000. usually we also call PVC Resin S1000. Its K-value is K67.
