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.
Titanium dioxide is not unfamiliar to those involved in the chemical industry. Titanium dioxide is currently the highest-quality white pigment in the world, mainly used in plastics, coatings, paper, ink, chemical fiber, cosmetics and other industries. So what are the top five brands of titanium dioxide in China with good reputation? Let’s take a look.
Barium sulfide is produced by carbothermic reduction of barium sulfate. Zinc sulfate is obtained from a variety of zinc products, often waste, by treatment with sulfuric acid.
Titanium dioxide, (TiO2), a white, opaque, naturally occurring mineral existing in a number of crystalline forms, the most important of which are rutile and anatase. These naturally occurring oxide forms can be mined and serve as a source for commercial titanium. Titanium dioxide is odourless and absorbent. Its most important function in powder form is as a widely used pigment for lending whiteness and opacity.
Durability is another important factor to consider when choosing a spark plug, and the Spark Plug 794 00082 excels in this area as well. With its robust construction and high-quality materials, this spark plug is designed to withstand the rigors of daily driving and maintain its performance over the long term. This means that you can rely on this spark plug to provide consistent ignition performance, even in the most demanding driving conditions.

• Super helix seal (seal with one-way two-step screw)
When selecting a gasket for the valve cover, it is important to consider factors such as material quality, durability, and compatibility with the specific engine model. High-quality gasket valve covers are designed to withstand the demanding conditions of automotive operation, providing reliable sealing solutions that contribute to the overall performance and safety of the engine. Choosing reputable suppliers and manufacturers known for producing high-quality gasket valve covers is crucial to ensure the reliability and longevity of these critical components.
Oil seals come in various shapes to fit the machines and substances to be sealed.
Figure 2 shows the structure and the names of the various components of the most typical oil seal.
The functions of the various components are also indicated in Table 1.
PTFE, on the other hand, is known for its chemical inertness, making it suitable for applications involving corrosive substances PTFE, on the other hand, is known for its chemical inertness, making it suitable for applications involving corrosive substancest shaped gasket.Most effective sealing is obtained with optimum shaft surface finishes. The sealing efficiency is affected by the direction of the finish tool marks and the spiral lead. Best sealing results are obtained with polished or ground shafts with concentric (no spiral lead) finish marks. If you must use shafts with spiral finish leads, they should lead toward the fluid when the shaft rotates.
