Textolites are called varieties of laminated plastics reinforced with fabrics. Thermosetting synthetic resins play the role of a bonding element. And it is not so important what kind of textolite is considered. What it is, easy to understand even by description
Some parameters and properties
Depending on the nature of the fibers, the PCBs are divided into several groups.
- Basalt textolites based on basalt fibers.
- Carbon textiles from carbon.
- Asbestos-laminate with asbestos fibers.
- Fiberglass laminated glass fibers of various types.
- Organo-textolites from artificial and synthetic fibers.
- Textolites proper, cotton fibers here
There are other varieties. Twill, satin, linen - types of weaving, which distinguish the threads themselves. Different may be surface density, thickness, number of threads per unit length in the direction of the warp and weft of the fabric, the structure and thickness of the thread or bundle. There is a special technology due to which they receive textolite. What is it, we have already figured out.
If the interlayer strength should be particularly high, multilayer fabrics are used. Sometimes there are products where the fibers are made from several varieties of materials.
What else to look for?
The manufacturing technology, the quantity and properties of the binder, the characteristics of the fabric itself, the nature of the fibers - parameters that determine what qualities the textolite itself will have, are also important. As for the production process itself, its basis is layered winding or laying of fabrics when a binder is applied to the mandrel in the form of the product. Foil textolite is produced in the same way. Next, molding takes place. In addition, textolite plates, plates or sheets must undergo mechanical processing.
Not only fabrics, but also binding elements playing the role of impregnation for the filler can be diverse in composition. Thermosetting synthetic resins most often fulfill this role, foil textolite is no exception.
About the advantages and other parameters
There are a number of qualities inherent in such a material as textolite. What it is is easy to understand from the description of its characteristics.
- The operating temperature range is from -40 to +105 degrees, if the current frequency is about 50 Hz, the relative humidity is maintained .
- Textolite is a good dielectric, which makes it an indispensable assistant in the electrical and energy industry.
- Easy machining.
- High strength.
- Low density.
- Low coefficient of friction.
Additional Information
Sheet textolite is used in many areas of life. It can be structural, anti-friction, friction, electrical insulating, heat-insulating and radio engineering material.
In many ways, this contributes to the ability to easily endure mechanical loads, even quite serious ones. So it is especially widely used in the electrical engineering industry. Based on the PCB, various parts with a structural purpose are manufactured.
Scopes and new opportunities
For the production of rings, plain bearings, bushings, ornamental textolite is used. What is this, you can understand even without special dictionaries. In the cushioning panels and gaskets, you can also see this material.
In gearboxes, in the distribution mechanisms of various engines, in gearboxes, the presence of bevel and cylindrical gears based on a material such as textolite is often noticeable. The price is different. Elements of centrifugal pumps, ball mills, turbines are textolite bearings. Textolite can successfully replace getinaks as a material for the production of electrical insulating parts. The bases for printed circuit boards are made of PCB in radio electronics. In addition, in modern tournaments, it is textolite that becomes the basis for the manufacture of weapons - such an application is quite unexpected.
A little about brands
There is another type of textolite, which is called asboplasty and is isolated separately. This is a fire-resistant and durable material that can withstand heat up to +250 degrees. It is characterized by chemical resistance, anti-corrosion and electrical insulation properties. The type of binder and filler largely determines what characteristics a particular product will possess. For example, materials made from anthophyllite asbestos give high acid resistance. The manufacturing method and degree of filling can also have an effect on existing parameters. In each case, everything is determined individually, this should be monitored separately.
