Plastic Injection Clear Housing
The transparency of the plastic injection transparent shell matrix resin itself has a great influence on the transparency of PP plastic products. In order to improve PP transparency, a small amount of polyacrylate resin with good transparency and compatibility can be added.

The steel strip type sulfur granulator has been applied to the sulfur recovery process for nearly 20 years, and the processing capacity of a single unit is small. With the rapid growth of China's refining capacity, the new project is basically 10 million tons. Due to the large amount of imported crude oil, the sulfur content is relatively high, and the sulfur recovery capacity of each refinery reaches 200,000 to 300,000 tons/year. Refining companies urgently need a single sulfur granulator with a significant increase in production capacity to meet the demand for plant sulfur recovery. Nanjing Sanpu sharply captured this market information. It has developed a new type of large-capacity rotary drum granulator for three years. Its maximum single-product capacity is five times that of the steel belt granulator.
Compared with steel belt granulator, rotary drum granulator does not need to replace large wearing parts, and the loss of ton product equipment is only 1/20 of the former, and the continuous long-term running time is longer. If the equipment is operated at 8,000 hours/year, a steel belt granulator needs to be replaced in 1~2 years at a cost of 400,000 to 450,000 yuan. However, the annual cost of equipment and spare parts for the rotary drum granulator is only It is 20,000 yuan/year. At the same time, the main part of the drum granulator is only 1/3 of the floor area of ​​the steel belt granulator, which can save the company more investment in infrastructure and other infrastructure. In addition, the selling price of rotary granulator is only 1/2 of imported equipment of the same type in foreign countries, which can save a lot of money for the company.
(1) the inorganic nucleating agent mainly consists of ultra-fine talc powder and SiO2, and also includes calcium carbonate, mica powder, inorganic pigments and fillers, etc., which is cheap in price and rich in source, but has certain influence on the gloss and transparency of the products.
(2) organic nucleating agent organic nucleating agent is a kind of organics with low relative molecular weight, represented by sorbitol and its derivatives. It has good compatibility with matrix resin and can significantly improve product transparency and surface gloss.
(3) in the case of sorbitol, when the amount of nucleating agent exceeds 0.3%, the effect of transparency improvement is not obvious, and even decreases. However, when the dosage is less than 0.2%, the nucleation quantity is insufficient and the transparency is not increased enough. It can be seen that the amount of nucleating agent should be between 0.2-0.3%. Therefore, suitable nucleating agent content can better improve the transparency of PP.
Nanjing Sanpu New Rotary Sulphur Granulator Capacity Increases Significantly
Nanjing Sanpu Granulation Equipment Co., Ltd. has developed a new type of large-capacity sulfur granulator, rotary drum type sulfur granulator, which has sold nearly 30 sets since it was put on the market. After a long period of application inspection and further technical improvement, the granulator has now formed a 15/20/25/30 tons/hour specification equipment product, and the maximum single-machine capacity is 5 times that of the steel belt granulator.
