It is reported that the company has successfully developed a JZW screw pile driver with independent intellectual property rights.
The JZW screw pile driver is designed to have a hole depth of 24 meters. The shape of the hole is different from that of an ordinary long auger. It is thread-like (equivalent to an internal thread), and the hole of the long spiral drill is cylindrical. Compared with the hole formed in the shape of a thread, the bearing capacity of the thread-shaped hole is doubled, and the amount of the poured concrete is greatly reduced, the construction cost is reduced, and the market prospect is wide.
JZW thread pile machine has obvious advantages, and the production difficulty is much longer than long screw pile machine. Due to the need to leave a complete thread-pile hole in the soil layer, it is necessary to synchronize the rotation speed of the drill pipe with the falling (or rising) speed to ensure the thread forming, otherwise the thread will be completely destroyed. To solve this technical problem, Fangyuan Group adopts the method of variable frequency speed control to achieve the requirements of synchronization.
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.
