Hunan Hengzhi Introduces New HZCLY90 Hydraulic Drilling Rig

Recently, Hunan Hengji Rock Drilling Co., Ltd. has newly launched the HZCLY90 all-hydraulic drilling rig, which is simple to operate and uses an excavator chassis for operation. The working platform can rotate 360 ​​degrees, which is convenient for drilling and positioning, and it can also save positioning time. Provide work efficiency.
HZCLY90 hydraulic drilling rig is a new type of drilling rig specially developed for the address diversity of the drilling and blasting project. It can be widely used in the shallow blasting of various rock formations such as railways, highways, hydropower, mining and urban construction. . This product adopts patented technology, integrates and optimizes a number of advanced and practical rock drilling technologies and engineering vehicle manufacturing technologies. After the provincial and ministerial level technical achievements and new product identification, the products reach the international advanced level. (This article comes from Hunan Hengzhi)

PVC RESIN SG8

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 production process of PVC Resin SG8 and PVC RESIN SG5 is basically the same, and the production equipment is exactly the same. The main difference lies in the formulation of additives, polymerization temperature, reaction pressure and so on. The reaction temperature and reaction pressure of SG-8 resin have basically reached the working pressure limit of the polymerizer. The reaction requirements are relatively strict, and the requirements on operation, safety, technology, and personnel quality are more stringent, and the resin quality is more difficult to control.
