Polyvinyl alcohol (PVA) Polyvinyl alcohol foam embolic microspheres are medical substances used for embolization of blood vessels. They are mainly composed of polyvinyl alcohol andhttps://www.elephchem.comor polyglycolide and are specially treated to enable them to swell and embolize blood vessels. Such microparticles are often used in intravascular surgery to prevent blood from flowing into and contaminating the surgical area. In addition, they can also be used to treat ischemic stroke and other vascular diseases. Features of polyvinyl alcohol foam embolic microspheres include: it can swell upon contact with blood and quickly solidify, thereby effectively embolizing blood vessels. The microspheres are degradable and will be absorbed by the body after a period of time, which helps reduce the risk of complications. In addition, it can be combined with other substances (such as drugs) to achieve specific therapeutic purposes. When using polyvinyl alcohol foam embolic microspheres, strict guidelines and standard operating procedures need to be followed.

As a new type of thermal conductive material, thermal conductive PVA (polyvinyl alcohol) film has excellent thermal conductivity, good mechanical strength and processing performance. The preparation of thermal conductive PVA film mainly includes raw material selection, blending modification, film forming process and post-processing. Raw material selection: The main raw material of thermal conductive PVA film is polyvinyl alcohol resin, and a certain amount of thermal conductive filler, such as oxygen, needs to be added Aluminum, boron nitride, etc. The addition of these fillers can effectively improve the thermal conductivity of PVA films. Blending modification: the polyvinyl alcohol resin is mixed with the thermal conductive filler in a certain proportion, and the blending modification is carried out by high-speed stirring, ball milling and other methods. During the blending process, the filler particles are uniformly dispersed in the resin matrix to form a thermal conductivity network, thereby improving the thermal conductivity of the material. Film forming process: the blended modified slurry is made into a film by casting, calendering or extrusion processes. In the film forming process, parameters such as temperature, pressure and speed need to be controlled to ensure the thickness, uniformity and surface quality of the film. Post-treatment: Post-treatment processes such as drying and heat setting need to be carried out after film formation to eliminate the internal stress inside the film and improve dimensional stability.

PVA 1. Temperature rise dissolution method The temperature rise dissolution method is one of the most commonly used methods for dissolving PVA. Add PVA powder 2. Dissolution by auxiliary agent In addition to directly adding PVA to water for dissolution, the solubility and stability of PVA can also be improved by adding auxiliary agents. Common auxiliary agents include acetone, methanol, ethanol, phenol, etc. These auxiliary agents can form hydrogen bonds or other interaction forces with PVA, thereby improving solubility. The addition of auxiliary agents can also shorten the dissolution time of PVA. 3. Slow cooling and dissolution The slow cooling method is a special PVA dissolution method, which is suitable for the preparation of polymers, micro-nano particles, films, fibers and other materials. The basic principle of the slow cooling method is to add PVA powder into water, heat it to dissolve it, and then slowly cool it down to make the PVA molecules self-assemble to form nanoparticles, nanofibers or films. The slow cooling rate has an important influence on the self-assembly process of PVA. Generally speaking, the slower the slow cooling rate, the more complete the structure of the PVA self-assembly. The slow cooling method is mainly suitable for the preparation of micro-nano materials. 4. Gas phase dissolution The gas phase method is a relatively new PVA dissolution method. In this method, the PVA solid enters the atmosphere through the dissolution hopper. By controlling the temperature, pressure and atmosphere composition, the PVA solid is directly evaporated into gaseous molecules, and then transported to other equipment through a transmission pipe for reaction or solidification to form a corresponding block. Unlike the traditional dissolution method, the gas phase method can prevent the PVA molecules from being affected by water decomposition, thereby maintaining the integrity and quality of the material.

PVB Safety glass produced using all-resin PVB film has superior optical properties, higher light transmittance and lower haze, making the finished glass more transparent. For example, if multiple layers of PVB are used to make laminated glass, the advantages of all-resin PVB will be It will be more obvious. Secondly, the yellowing value of the film is very low and the film is whiter, so that the finished glass will not turn yellow and is suitable for ultra-white laminated glass. The all-resin film is more durable and can withstand the sun and rain. It will not cause degumming, bubbles, aging and other undesirable phenomena after long-term use. PVB interlayer film is widely used in construction, automobile, photovoltaic and other industries. PVB interlayer films produced with special formulas are also widely used in aerospace, military and high-tech industries, such as aircraft, aerospace products, military instruments, solar cells and solar receivers. It is currently the best adhesive material for manufacturing laminated and safety glass in the world.
