“As the national environmental protection efforts increase, the environmental protection costs of our polyaluminum chloride (main water purification agent) companies that serve the environmental protection industry are also increasing. In the face of market competition, polyaluminum chloride companies have begun to change. Concept, rethinking the price-priority business model, and at the same time, follow the new requirements and new procurement models of downstream companies, and take the road of development that gives priority to quality.†This reporter interviewed at a production site of water purifying agent in the Henan Gongyi area in Henan Province. The most representative view. Gongyi City Imported Imported Gully Purifying Materials Factory mainly produces filter materials, fillers, and polyaluminum chloride, becoming the birthplace of water purification agent manufacturers in the region, and also spurring water purification agents represented by polyaluminum chloride. Product manufacturing companies have rapidly emerged in the surrounding areas of Gongyi. At present, there are more than 80 polyaluminum chloride production enterprises in Gongyi City. The polyaluminum chloride products produced in Gongyi City account for more than 60% of the national production capacity and have become the largest water purification agent production base in the country. The head of the plant, Li Zongliang, said that the current sales situation is not the same as the original one. Customers come and talk about quality first, and then talk about prices. Unlike the original only talk about price, do not pay much attention to quality. According to reports, companies that started from low-content products (below 28%) have almost always gained market share with price advantage. They once opened most of the domestic sewage treatment market, and their production and sales volume increased, resulting in improved profits. However, in the past two years, due to the simple production technology of low-content varieties, waste water and waste slag are difficult to handle, prices have been gradually reduced, and corporate profit margins have shrunk to the cost margin. “After the polyaluminum chloride product hits the market at a low price, the side effects gradually emerged. Especially if business is booming this year, companies will not be able to earn money because of the adoption of price-priority business models. Some low-level products In the vicinity of the cost zone, the cost of environmental protection has gradually increased, and sales prices have begun to gradually decline, while those with high-content products (more than 28%) and tap water treatment grade products have increased in price and profit margins have gradually increased. This forced the water purification agent production companies to change their original price-priority business ideas and shift to quality priority. At the same time, this is also the main reason why our low-level products gradually fade out of the market and focus on the development of high-quality water purifiers.†The reporter said. According to Shi Qifeng, general manager of Guangzhou Lens Biological Purification Materials Co., Ltd., the Guangzhou region is one of the largest regions in China that consumes polyaluminum chloride. In the past few years, they purchased products mainly to see whether the price is favorable, and the products with content of 24%~26% are all Can use. However, since the beginning of April, the environmental protection department has increased the indicators for wastewater discharge control, testing has become more stringent, and customer requirements have become higher and higher. They all use more than 28% of their products. Although the price per ton is higher by about 200 yuan, customers no longer only value the price, but follow quality first. According to statistics, the company has purchased 6,000 tons of polyaluminum chloride this year. The equivalent sales volume is obviously about 5% higher than last year, and the purchase plan for next year is expected to exceed 10,000 tons. “In order to reduce transportation costs and save operating costs, water purification agent manufacturers have also begun to adopt regional sales transfer models, implement centralized transportation, and diversify sales, all of which have prompted the company's business thinking to shift from price priority to quality priority.†A professional manufacturer in Gongyi City The coke manager of the polyaluminum chloride company told reporters. The so-called centralized transportation and decentralized sales means that the high-content products are transported to the areas where the consumer manufacturers concentrate, and a set of chemical material devices are built in the area and converted into liquids for sale. This will not only reduce the transportation costs of liquid products, but also reduce the disposal cost of waste slag produced when low-level products are processed. At the same time, it also takes into account the needs of some local small customers, and has played a role of “reforming zeroâ€. This method is both environmentally friendly and effective. It is closer to market demand and is one of the main reasons for this year's high sales of polyaluminum chloride. It is understood that with the gradual standardization of China's sewage treatment industry, the pace of reorganization of wastewater treatment companies has begun to accelerate. According to a person in charge of Jiangxi Hongcheng Water Industry Co., Ltd., the company plans to restructure all sewage treatment plants in the province and has made significant progress. After the reorganization is planned to be completed next year, it will unify the procurement of water purification agent products. At that time, they will send technicians and business personnel to field inspections of water purification agent manufacturers, view production processes, and manage wastewater treatment companies in a unified manner based on quality-first procurement models. From this point of view, the production of water purifying agents will inevitably experience “transformation†from price priority to quality priority. 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.

(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.
