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.
Application field of polyvinyl butyral -- electronic adhesive
Polyvinyl butyral contains hydroxyl, vinyl acetate and butyraldehyde, which has high bonding properties. Phenolic Resin was added into PVB ethanol solution to make adhesive, which can be used for a long time at 120 ℃. The product has strong adhesion to metal, wood, leather, glass, fiber and ceramics; FRP can be manufactured to replace non-ferrous metals such as steel, aluminum and copper; The adhesive made by adding this product and curing agent into epoxy resin is often used for bonding and assembly of electronic instrument components, bonding between metal and porous materials, emergency repair, etc. it can also be used in the field of electronic ceramics. 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.
Par ailleurs, dès lors que l'on recherche une certain transparence dans les travaux artistiques, son pouvoir opacifiant et son pouvoir dégradant des couleurs pas trop élevés le désignent pour remplacer le dioxyde de titane trop opaque et trop dégradant (§ Des Liants et des couleurs aux éditions EREC)
Titanium dioxide has also been classified as a possible human carcinogen by the International Agency for Research on Cancer, which has caused concern about its use in food products. This classification, however, is currently based on limited evidence from animal studies that involved the inhalation of titanium dioxide particles that increased the risk of lung cancer.
638 zz bearing. The high speed capability of the 638 ZZ bearing makes it suitable for applications that require high rotational speeds, such as spindle motors and turbochargers.
- Spherical Roller Bearings: Spherical roller bearings are well-suited for applications where heavy radial loads, shock loads, and moderate axial loads are present, and where misalignment accommodation is required.
A well-engineered bearing ensures consistent and uniform mixing, preventing aggregate segregation and ensuring the homogeneity of the concrete mix A well-engineered bearing ensures consistent and uniform mixing, preventing aggregate segregation and ensuring the homogeneity of the concrete mixconcrete mixer drum bearing. Moreover, its ability to withstand the abrasive nature of the concrete mixture and resist corrosion extends the lifespan of the mixer, reducing maintenance costs and downtime.The investment is expected to have a positive impact on the bearing industry, as it will drive innovation and competition. Other manufacturers are likely to follow suit, investing in new technology to improve their own efficiency and quality.
Moreover, these bearings often come with rubber seals or shields to protect against contamination, extending their service life Moreover, these bearings often come with rubber seals or shields to protect against contamination, extending their service life61908 bearing.
- Thrust ball bearings are specifically designed to support axial loads, which are forces acting parallel to the shaft's axis. They are used in applications where the primary load is axial, such as in automotive transmissions, machine tool spindles, and thrust applications.
