Polyvinyl butyral (PVB) is dissolved into 12 ~ 14% solution with ethanol and made into film. It is used for printing paper film of ceramic (or enamel) products. The fired ceramic (or enamel) patterns have bright color and smooth texture. The flower paper is characterized by convenient use, low cost, smaller than the original glue, greatly reducing the decal process and high color burning rate. At present, most porcelain factories in China have formed relatively formal production lines for standardized production. Therefore, the demand for PVB in the ceramic (or enamel) flower paper industry is increasing.

In the development of ceramic integrated electronic circuits, this product with medium viscosity and low hydroxyl is used as ceramic powder adhesive to increase the primary strength of ceramics.

Application field of polyvinyl butyral -- copper foil adhesive

Polyvinyl butyral (PVB) and phenolic resin cooperate to produce copper foil adhesive, which is used in the production of copper clad laminate. It has good peel strength and tin welding temperature resistance, and is widely used in various fields.

Application field of polyvinyl butyral - self adhesive enamelled wire paint

Polyvinyl butyral is the main raw material of self-adhesive enamelled wire paint. After the enameled wire is wound and formed in the electrodes of motors, electrical appliances and instruments, as long as it is heated for several minutes at a certain temperature or treated with appropriate solvent, the coils can be bonded together by themselves without impregnation and drying.

Resumo–Este artigo discute a descoberta de litopônio fosforescente em desenhos de aquarela do artista americano John La Farge datados de entre 1890 e 1905 e a história do litopônio na indústria de pigmento no final do século XIX e início do século XX. Apesar de ter muitas qualidades desejáveis para o uso em aquarela branca ou tintas a óleo, o desenvolvimento do litopônio como um pigmento de artistas foi prejudicado por sua tendência a se escurecer na luz solar. Sua disponibilidade para e uso por parte de artistas ainda não está clara, uma vez que os catálogos comerciais dos vendedores de tintas geralmente não eram explícitos na descrição de pigmentos brancos como algo que contém litopônio. Além disso, o litopônio pode ser confundido com o branco de chumbo durante o exame visual e sua fosforescência de curta duração pode ser facilmente perdida pelo observador desinformado. O litopônio fosforescente foi documentado em apenas um outro trabalho até hoje: uma aquarela de Van Gogh. Além da história da manufatura do litopônio, o artigo detalha o mecanismo para a sua fosforescência e sua identificação auxiliada pela espectroscopia de Raman e espectrofluorimetria.

As they mimic the synapses in biological neurons, memristors became the key component for designing novel types of computing and information systems based on artificial neural networks, the so-called neuromorphic electronics (Zidan, 2018; Wang and Zhuge, 2019; Zhang et al., 2019b). Electronic artificial neurons with synaptic memristors are capable of emulating the associative memory, an important function of the brain (Pershin and Di Ventra, 2010). In addition, the technological simplicity of thin-film memristors based on transition metal oxides such as TiO2 allows their integration into electronic circuits with extremely high packing density. Memristor crossbars are technologically compatible with traditional integrated circuits, whose integration can be implemented within the complementary metal–oxide–semiconductor platform using nanoimprint lithography (Xia et al., 2009). Nowadays, the size of a Pt-TiOx-HfO2-Pt memristor crossbar can be as small as 2 nm (Pi et al., 2019). Thus, the inherent properties of memristors such as non-volatile resistive memory and synaptic plasticity, along with feasibly high integration density, are at the forefront of the new-type hardware performance of cognitive tasks, such as image recognition (Yao et al., 2017). The current state of the art, prospects, and challenges in the new brain-inspired computing concepts with memristive implementation have been comprehensively reviewed in topical papers (Jeong et al., 2016; Xia and Yang, 2019; Zhang et al., 2020). These reviews postulate that the newly emerging computing paradigm is still in its infancy, while the rapid development and current challenges in this field are related to the technological and materials aspects. The major concerns are the lack of understanding of the microscopic picture and the mechanisms of switching, as well as the unproven reliability of memristor materials. The choice of memristive materials as well as the methods of synthesis and fabrication affect the properties of memristive devices, including the amplitude of resistive switching, endurance, stochasticity, and data retention time.

  • 13. Solar Security Lighting

  • In addition to the technical advantages, pole-mounted solar panels contribute positively to the environment. By harnessing solar energy, they help reduce reliance on fossil fuels, thereby decreasing greenhouse gas emissions. This shift towards sustainable energy sources is crucial in combating climate change and promoting a healthier planet for future generations.


  • Despite the initial investment, the cost of a 2kW solar system can often be mitigated through various incentives and rebates. Many states and local governments offer tax credits, rebates, and even grants to homeowners who choose to install solar panels. For example, the Federal Investment Tax Credit (ITC) allows homeowners to deduct a significant percentage of the installation cost from their federal taxes, providing substantial savings.


  • 1. Cost-Effectiveness One of the most significant advantages of string inverters is their cost-effectiveness. Since a single inverter can handle multiple panels, the initial investment for a solar power system can be lower than using microinverters. This makes string inverters particularly appealing for homeowners and businesses looking to maximize their return on investment.


  • A solar generator typically refers to a combination of portable solar panels, a battery, a battery charger and an inverter. These all make up one device — the generator. With it, you can absorb solar energy, then store and distribute it when needed. 

  • 4. Scalability Hybrid inverters can be easily scaled to accommodate growing energy needs. Whether it’s a larger home or an increasing number of appliances, users can expand their solar and storage capacity accordingly.


  • 1. Efficiency Modern 3 kW inverters typically boast high efficiency rates, often exceeding 95%. This means a significant portion of the solar energy captured by the panels is converted into usable electricity, minimizing losses during the conversion process.


  • 5. First Solar While primarily known for its thin-film solar technology, First Solar has also made strides in the bifacial market. Their commitment to sustainable energy production and innovation in designs has positioned them well in the ever-evolving solar landscape.


  • Size and Dimensions


  • The Benefits of Using an Off-Grid 3kW 48V Inverter


  •  

  • As the world shifts towards renewable energy solutions, off-grid solar systems have emerged as a vital option for many households and businesses seeking energy independence. At the heart of these systems is the solar inverter, specifically designed to convert the direct current (DC) electricity generated by solar panels into alternating current (AC) electricity that can be used by standard appliances. This article explores the key players in the off-grid solar inverter market, their innovations, and the role they play in promoting sustainable energy practices.


  • Affordability is another crucial aspect driving the adoption of solar technology. The global solar market has witnessed a sharp decline in prices over the past decade, primarily due to advancements in manufacturing techniques and economies of scale. The cost of solar photovoltaic (PV) systems has decreased by nearly 90% since 2010, making solar energy a competitive alternative to fossil fuels. Incentives, tax credits, and government initiatives have also played a vital role in making solar installation more accessible for homeowners and businesses alike, further propelling the industry forward.
