HCM Machinery Bowei dry grinding machine factory learned that lithium film continued to discharge glass fiber boom bottom. In order to promote the development of lead-acid battery industry and respond to the needs of national energy and environmental protection policies, the development of ultra-thin high-strength wet battery separator is imminent. A number of domestic leading enterprises raised funds to put into production glass fiber lithium battery diaphragm industry, the market prospects are broad. Mingguan New Materials announced on December 14 that the company used the raised funds of 931 million yuan to increase capital to Mingguan Lithium film for the investment project "Mingguan Lithium Film Company's annual output of 200 million square meters of aluminum plastic film construction project". After the completion of the capital increase, the registered capital of Mingguan lithium film increased from 100 million yuan to 1.031 billion yuan. The company used the raised funds of 416 million yuan to increase the capital of Jiaming Film for the project "Jiaming Film Company's annual output of 100 million square meters of fluorine-free backplane construction project". After the completion of the capital increase, the registered capital of Jiaming Film increased from 50 million yuan to 466 million yuan. Sinoma lithium film raising volume of about 6.5 billion yuan to increase capital and expand shares to highlight the strategic position of lithium film, the company's new film line after the production of cost reduction, profit repair is significant, and increase capital to enable production expansion speed, lithium film business is expected to achieve volume profit rise. Maintain the company's 2022-24 eps2.21/2.61/2.91 yuan, maintain the target price of 38.67 yuan. Nanjing Glass Fiber Research and Design Institute Co., Ltd. is the only comprehensive research institute engaged in glass fiber research, design and production. The company established the first ultra-thin and high-strength wet glass fiber battery diaphragm production line with an annual output of 1500 tons, and the ultra-thin and high-strength glass fiber battery diaphragm series products prepared have occupied a large number of domestic markets, and are widely used in the continuous clean production of panel grids.

The characteristics of wet glass fiber diaphragm: wet glass fiber cell diaphragm is made of glass microfiber with a diameter of 0.5-3μm by wet process, which has good mechanical strength, compressive strength and resilience, excellent chemical resistance and temperature resistance. In view of the requirements of clean production and high specific energy performance of lead-acid batteries, the characteristics of thin thickness, high puncture strength, high tensile strength, temperature resistance and anti-adhesion of wet battery membranes are proposed at this stage. The technical content of domestic diaphragm products is slowly improved, the homogenization is serious, the ultra-thin diaphragm has not been industrialized, and its thickness stability and strength performance can not be applied to the clean production of lead-acid batteries and the development needs of high specific energy performance. Nanjing Glass Fiber Research and Design Institute Co., Ltd. built a wet glass fiber membrane puncture damage model, revealed the puncture damage law of different components of the diaphragm, optimized the high-strength diaphragm multi-component fiber formula, and improved the membrane resistance to dendrite puncture. Self-developed fiber self-reinforcing and temperature-resistant modification technologies, which solved the problems of coupling diaphragm thickness and strength and curing adhesion in battery clean production, broke through the ultra-thin and high-strength glass fiber preparation technology, and formed ultra-thin and high-strength glass fiber battery diaphragm products. Optimized and integrated ultra-low concentration dehydration technology and high uniform pulp distribution technology, developed pH real-time control system and multi-stage slurry screening and other key equipment.

Lithium film profit breakthrough, volume and price rise, glass fiber lithium electric diaphragm line products market prospects.HCM Machinery is a focus on the development and production of ore dry grinding mill enterprises, the company has been established for more than 30 years, Hongcheng Raymond mill, vertical mill, super mill, ring roller mill can grind more than 100 kinds of non-metallic ore, slag, solid waste, more than 5000 mill cases in many places in the country, mill quality is stable, high output, low consumption, energy saving and environmental protection.
