Caustic soda can be produced by ionic membrane process and causticizing process. Two methods of production of liquid alkali, tablet alkali, granular alkali, our factory has been doing for many years.Causticizing process introductionSodium hydroxide, chemical formula is NaOH, is a strong alkali
Ceramic granular sand rotary kiln, also known as rotary kiln, calcining kiln or simply referred to as rotary kiln, may sometimes be called by the name of the processed materials. Depending on the type of materials being processed, it may also be named after the name of the processed materials. This
In modern industrial production, the grinding aid, as a special chemical additive, plays an irreplaceable role in enhancing the grinding efficiency, reducing energy consumption, and improving product quality. Today, Henan Zhengmin Machinery Co., Ltd. will delve into the different types of grinding a
With the continuous improvement of the country's requirements for green development and comprehensive utilization of resources, exploring effective, environmentally friendly and economical coal gangue treatment technologies has become an urgent task. Suspension calcination for decarbonization, as a
As a key piece of equipment in the industrial grinding process, the production capacity of a ball mill is influenced by a variety of factors. To enhance production efficiency and reduce energy consumption, it is necessary to have a thorough understanding and optimize these influencing factors. The m
The Yunnan-Guizhou-Sichuan region is the core area of phosphorus mineral resources in China. For a long time, yellow phosphorus enterprises have been facing difficulties in processing low-grade phosphorus ores: the fine ore powder after beneficiation has a high moisture content (generally > 15%), is

PP/PE three-layer co-extruded lithium battery separator castiPP/PE three-layer co-extruded lithium battery separator casting and stretching production lineng and stretching production line

Schematic diagram of the new dry-process lithium battery separator technology:

Regarding the new process for stretching lithium battery separators:
Key points of the new process:
The online heat treatment of the materials is carried out without the need for the oven step in the old process. After extrusion and compounding, it can directly enter the stretching machine.
Spool diameter:
In the new process, the spool diameter can reach 1000mm (for four layers), and it can be increased to 32 layers. In the old process, the spool diameter was only 550mm (for four layers), and it could only reach 20 layers.
Comparison Table of New and Old Processes:
| Oven pre-treatment | Unwinding diameter | Total number of floors | Spool length | Production line length | Product quality | |
| Old process | Required | 550 | 20 | 1 times | 27 meters | Generally |
| New process | Not necessary. | 1000 | 32 | 3.5 times | 55 meters | High |
