    "Knocked neck"

    .
    There is still a "film" of distance for China's lithium battery dream to be reflected in reality

    .
    This distance seems very short and short, but it is extremely difficult to go over

    .
    For domestic aluminum-plastic film companies, it is not only a challenge, but also an opportunity

    .
    ? ▲The picture shows Yan Hongjia, chairman and general manager of Mingguan New Materials, explaining Mingguan's aluminum-plastic film strategy? According to Yan Hongjia, Mingguan aluminum-plastic film extends from the solar backplane.
    The solar backplane has an aluminum-based backplane.
    The structure is similar to that of the aluminum-plastic film.
    The company's more than 10 years of dry composite and thermal film production technology in the backplane field have provided a lot of experience data and technology accumulation for the proposal and design of the aluminum-plastic film dry-heat composite technology

    .
    ? "Different from the traditional path of'low-end entry, transformation and upgrading', Mingguan New Materials has been positioned as a mid-to-high-end market at the beginning of the expansion of the aluminum-plastic film field.
    This means that the company's high standards and strict requirements for products also mean Only by achieving the ultimate in reliability, safety and other indicators, can we truly provide customers with high-quality, high-value-added products, and continue to

    empower them in continuous innovation and upgrading .
    " Yan Hongjia said

    .
    ? At the same time, in order to meet the differentiated needs of different markets, Mingguan New Materials has developed a variety of products with different specifications, different colors, and adaptable to different application scenarios: For the application of smart phones and flexible wearable electronic products, Mingguan has developed Developed ultra-thin black and silver aluminum-plastic film; in the mobile power, TWS, electronic cigarette and other markets, developed 113 silver film and black film series products with high drawing depth; in the fields of new energy vehicles, two-wheeled electric vehicles, and energy storage , Developed products of 153 specifications, and made corresponding product layouts for special fields such as solid-state batteries and supercapacitors, and formed a market layout and coverage of full-field and full-scene applications in the soft pack battery market

    .
    ? Yan Hongjia said that, relying on the three major bases in Jiangxi, Suzhou, and Vietnam, Mingguan solar backsheets will have an annual production capacity of nearly 20GW.
    The POE film project for photovoltaic modules with an annual output of 12GW is under construction, and the aluminum-plastic film fundraising project is progressing smoothly.
    , The company will make overall arrangements to promote the development and production of corresponding products according to the market demand of aluminum-plastic film, and make a good technical reserve for the next 3-5 years.
    It is expected that the company's production capacity will be greatly released this year

    .
    ? Mingguan aluminum-plastic film product characteristics and innovative applications? According to Li Chengli, the advantage of Mingguan aluminum-plastic film dry-heat composite technology is that it retains the characteristics of the dry process while taking into account the advantages of thermal method in terms of electrolyte resistance and water resistance.
    Technological advantages, the thermal process MPP resin is modified into a dry processable nano-scale suspension slurry, a layer of MPP resin layer is formed on the surface of the material through the coating method, and the fluidity of the resin is improved before compounding.
    The thermal resin can be carried out at low temperature and low pressure composite strength, and the original mechanical properties of the material are retained

    .
    The comprehensive performance of the aluminum-plastic film in terms of deep drawing, appearance, electrolyte resistance and water resistance has been comprehensively improved

    .
    ? ▲The picture shows Li Chengli, Technical Director of Mingguan Lithium Membrane, introducing Mingguan aluminum-plastic film products? Up to now, Mingguan New Materials' power and energy storage aluminum-plastic film (CAP153), except for PA/PP materials, other materials are domestically produced Or self-developed products, PP and PA are also in the stage of self-research and localization testing.
    It is expected that all materials will be localized within 1 to 2 years, completely unlocking all technical blockades of aluminum plastic film

    .
    ? Li Chengli said that Mingguan’s power storage aluminum plastic film is equivalent to imported products in terms of long-term electrolyte resistance, long-term boiling water, long-term dampness and heat, cold and heat shock, and punching moldability.
    In the domestic industry, it has obvious competitive advantages in performance

    .
    At the scene, he showed some experimental data

    .
    ? Resistance to electrolyte immersion: According to the 28-day test data, the peel value of Mingguan products is still above 15N/15mm, which is in the forefront of the industry level

    .
    Heat-sealing peeling force: The sealing peeling force of Mingguan aluminum plastic film in the one-sealing and two-sealing stages is not much different, and its packaging strength is equal to that of imported materials

    .
    Wet and hot water boiling limit experiment: Whether it is the double 85 experiment or the boiling limit, it is at the leading level of domestic and foreign counterparts

    .
    ? PP adhesive layer temperature resistance: at -25 ~ 120 ℃, the residual peeling force of Mingguan aluminum-plastic film is still above 13N/15mm, attenuation 57.
    65%; the residual peeling force of competing products is 8.
    58N/ 15mm, attenuation of 71%; both the peeling residual value and the attenuation amplitude are better than peers

    .
    The heat-sealing peeling force varies with temperature: The maximum heat-sealing strength of Mingguan aluminum plastic film under -20~120℃ alternating hot and cold conditions is 36.
    8%, which is far lower than the 78% variation range of the same industry

    .
    In addition, Li Chengli also showed relevant test data, showing that Mingguan’s 3C digital aluminum-plastic film has obvious advantages in terms of electrolyte resistance, heat-sealing sol resistance, shell warping, appearance and color, and appearance solvent resistance.
    It is also at the leading level in the entire industry

    .
    ? ▲The picture shows the site of Mingguan's new material aluminum-plastic film product promotion meeting? Li Chengli said that in order to truly realize localization of aluminum-plastic film, good consistency must be ensured

    .
    Relying on the experience accumulated in equipment and technology for many years, combined with the characteristics of products, Mingguan integrates the process to the greatest extent, reduces the control points, reduces the instability caused by the uncertainty in the product manufacturing process, and improves Product consistency, production efficiency and yield

    .
    At the same time, Mingguan’s material selection principles start with self-research, brand, strength (scale and R&D), etc.
    , to ensure the controllability of incoming materials

    .
    Incoming material inspection evaluates the detectable stability by sampling inspection and online inspection

    .
    At the same time, choose a suitable storage environment for the raw materials to avoid material abnormalities caused by storage problems

    .
    "Mingguan inherits more than 10 years of management experience in the backplane industry, standardizing the production process, standardizing the production environment, responsibilities of core positions, and automating data monitoring

    .
    Effectively prevent the loss of blocking processes, reduce material process risks, and improve product consistency
