Open the door of EU market with quality

On September 11, at Shenzhen Yantian Wharf, a batch of goods destined for overseas markets were being urgently shipped. This batch of 41.6 tons of small barrels of bleaching powder concentrate will soon cross the sea and enter supermarkets in European countries. From the first in Asia to the first in the world, Jianghan Salt Chemical Co., Ltd. paid close attention to the quality management of bleaching powder products in the whole process, and built a strong brand to expand the EU and Australian markets。

Every morning, the first thing Wang Hongli, the quality officer of the bleaching powder operation department, does when she goes to work is to open the computer to log in to the LIMS system and check the sampling data of raw materials, such as hydrated lime, of the bleaching powder concentrate the night before.

"Before entering the factory, the raw material supplier will provide the product test qualification report, but we will conduct the second sampling test." Wang Hongli told the reporter that as long as one indicator is unqualified, it will be returned or degraded, and the quality of bleaching powder concentrate must be controlled from the source.

As a highly effective disinfectant, bleaching powder essence has always been the "fist" product of Jianghan Salt Chemical, and has been sold to more than 80 countries and regions overseas.

In the past two years, the domestic market demand for disinfectants has continued to grow around epidemic prevention and control. "For a long time, the product quality of bleaching powder concentrate has adopted international standards." Tu Fei, deputy chief engineer of Jianghan Salt Chemical Industry and director of bleaching powder operation department, said.

Hydrated lime is the main raw material of bleaching powder concentrate. According to the demand for high-end disinfectant products in the international market, the quality of hydrated lime must reach the first class or superior products, and the produced bleaching powder concentrate can reach the standard.

"The slaked lime transported by the tanker has been bumpy all the way, and the sediment, small stones, and unburned limestone and coal ash have all sunk to the bottom. The surface sampling cannot find the quality problem of raw materials." Xu Zhenggang, deputy director of the bleaching powder operation department, said.

The Quality Inspection Department of Jianghan Salt Chemical Industry Co., Ltd., focusing on improving the accuracy of sampling, has brainstormed and improved the sampler for many times to ensure that each layer of samples can be collected, so as to truly reflect the quality of this batch of hydrated lime.

Now they have introduced a new process of rotary flash evaporation. When the blower blows away the products inside, it evaporates the water into gas instantaneously, and then the cyclone separator separates the gas-solid mixture. The drying can be completed in 8 to 12 seconds, which not only greatly improves the operating efficiency of the unit, but also increases the effective chlorine content of bleaching powder concentrate from 70% to 76%, and the whiteness by 3-5 points.

Control the production process, and the packaging process should not be sloppy.

The bleaching powder concentrate is mainly sold to overseas markets by water. During this period, it has to pass through the equator. A long period of high temperature and humid environment undoubtedly poses a huge challenge to the material, sealing, heat resistance, compression, shock resistance and fall resistance of the product's outer packaging.

"At present, there are 6000 barrels for packaging every day, and there are strict quality standards, finished product loading, and a set of strict procedures." Xu Zhenggang introduced that the packaging barrel should be sent to a professional organization for testing, and all items can only be used after passing the inspection; When packing, there are corresponding regulations on the materials and layers of partitions used between products.

Not long ago, the operation department of bleaching powder concentrate carried out a comprehensive upgrade and maintenance of the subcontracting machine with a package of less than 10kg, expanding the production capacity. At present, we have subcontracted more than 2000 tons of products that meet the needs of the European Union and Australian markets, which has reached the annual sales volume of similar products last year.

Good quality, wide market, strict quality control throughout the process, to ensure that bleaching powder concentrate products to expand the foreign market with excellent brand. By the end of August, Jianghan Salt Chemical had sold 47970 tons of bleaching powder concentrate this year, up 11.14% year on year.
