There are many grades of PVC. The viscosity or K value commonly used in the industry indicates the average molecular weight (or average degree of polymerization) of PVC, that is, the length of the PVC molecular chain, which determines the grade of the resin and the corresponding processing parameters. The molecular weight of the resin is related to the physical and mechanical properties of the product.
PVC used to be the largest general-purpose plastic in the world, and it is widely used. It is widely used in construction materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc
SG3 (K-70, S1300): mostly used for soft products, hoses, wires and cables, films, shoe materials, toys, auto parts etc.
PVC RESIN SG3 has high purity, less fish eyes, easy to blister, high temperature resistance, insulation, soft product texture, etc. It is mainly used to produce soft products such as wires and cables, agricultural films, conveyor belts, and daily plastic products.

Reflecting the development strength of our country's plastic bottles, we absolutely can't do without the R&D and manufacturing strength of blowing machine equipment. Through years of development, the domestic bottle blowing machine industry has been catching up with internationally renowned bottle blowing machine manufacturers in terms of learning and learning techniques, and has gradually formed its own advantages in the manufacture of bottle blowing equipment.
In fact, the bottle blowing machine must form its own advantages, can not be separated from the progress of production technology of related parts of the blowing machine. For example, the advancement of localization technologies for air compressors, compressors, and other related parts and equipment, and only the leading advantages and advancements in these parts and equipment in the complete domestic technology can promote the progress of the entire blowing machine industry.
China's bottle blowing machine development level is not invulnerable
Although the blow molding machine has developed rapidly in recent years, it does not mean that it has reached an impeccable level of production. There are still many problems that need to be improved. From blower equipment itself to product marketing and after-sales service, all aspects need improvement.
Blow Molding Machine Industry Survival Rule With the development of the domestic plastic bottle market, the plastic bottle blowing machine has also been rapidly developed. It is widely used in the beverage and pharmaceutical and cosmetics and food industries, and it has attracted more manufacturers to choose to blow the bottle. Machine to replace the previous bottle making tools.
Among the many products, multi-layer co-extrusion blow molding machines are very promising blow molding machines. With the increasing proportion of multilayer blown high barrier hollow products in the field of hollow products, multilayer blow molded products not only develop rapidly in the food packaging industry, but also in chemicals and cosmetics and medical hygiene and other industries. Packaging has also grown rapidly. Therefore, the development of the bottle blower stems from its excellent characteristics, and it will surely reach its peak in the next few years.
However, with the wide application, the requirements are also increasing. At present, the pharmaceutical industry has two urgent needs for blowing equipment. The first reason is that due to the continuous rise in the price of plastic raw materials, companies are constantly wondering how to reduce the cost of packaging to maximize profits. Therefore, it is necessary to use advanced blowing equipment to produce lighter weight bottles. Second, due to the ever-changing market changes, Manufacturers must respond flexibly to the shorter and shorter life cycle of medicine. These two urgent needs have caused a bottleneck for bottle blowing equipment suppliers.
In addition, in order to allow purchasers to feel more comfortable buying, blow-molding machine companies should enhance bottle-blowing after-sales service while ensuring quality. After all, small businesses are inherently less risk-bearing. They require a high level of service for all aspects of blowing machine companies. If they can meet professional technical guidance and long-term after-sales protection, the purchase volume of blowing machines will increase. .
Therefore, in the subsequent development process, the bottle blowing machine companies must face these problems in order to achieve long-term development. The industry must use its own advantages to seize the market, and then continue to strengthen technological innovation, establish a good brand image, and thus stabilize the market.
PVC Resin is a kind of non-crystalline linear polymer compound. The larger the relative molecular mass, the higher the viscosity, the higher the molecular weight, and the higher the tensile strength, impact strength, and elastic modulus of the product, but the flow of the resin melt Decline in sex and plasticity. The viscosity number is usually used to indicate the molecular weight of the polymer, and the polymer model is divided
The rapid development of blow molding machines has been adopted by a number of industries, mainly due to their distinct characteristics. First, the blow molding machine uses oil-free air bag locking technology, which results in large clamping force, low torsional force, and long life. Secondly, patented fly-out sealing technology makes it easier to seal, especially for wide-mouth bottle closures. In addition, the use of Keyence PLC, touch screen, easier operation and high reliability.
