When it comes to PET self-wrapping braided sleeves, laymen are basically not clear about it, but it only needs to talk about the maintenance and cleaning of computer power lines, speaker monitoring video lines, lighting, refrigerators, washing machines and other electrical appliances Products and their optical cables, motorcycles, vehicles, you may have some knowledge, let us master the performance and application of PET self-wrapping Braided Sleeve raw materials.
When the external reverse working voltage is limited, the external electric field and the construction electric field are further strengthened, the reverse saturation state current I0 has nothing to do with the reverse bias voltage value within the reverse working voltage range, when another reverse working voltage reaches the level , the compressive strength of the electric field in the space charge layer of the P-n junction reaches the whole process of free electron growth, a large number of oxygen vacancy pairs of electronic equipment are generated, and the reverse penetration current with a large value is called PET self-wrapped braided sleeve penetration. through.
There are many types of PET self-wrapping braided sleeve manufacturers. PET self-wrapped braided sleeve products can be divided into germanium braided sleeves and silica gel glass fiber tubes according to commonly used semiconductor materials, and can be divided into wave detection PET self-wrapped sleeves Braided casing, rectifier PET self-wrapped braided casing, voltage regulator tube PET self-wrapped braided casing, power switch PET self-wrapped braided casing, etc., according to the core tube structure, can be divided into point contact PET self-wrapped braided Sleeves, surface-contact PET self-wrapped braided sleeves, horizontal PET self-wrapped braided sleeves, and point-contact PET self-wrapped braided sleeves are filaments on the surface of optical semiconductor material chips.
Through a single pulse current, the touch end and the chip are firmly calcined to form a PN junction. Because it is a point contact, it can only be used for high-frequency and low-current power circuits based on small currents, such as tape recorder detection, etc. The surface touches the PET self-wrapped braided sleeve PN The total area of the junction is relatively large, allowing the conversion of AC current to DC power rectifier power circuit according to the key of the large current, the flat PET self-wrapped braided sleeve is a different silicone fiberglass tube, not only according to the large current, the performance is stable and reliable, the main Used in power switches, monopulse and high frequency circuits.
1. Compound fiber winding process (belonging to the fixed length method): In this process method, the dipping tank reciprocates with the rotating mandrel, and the long fiber glass filaments are placed at a certain oblique angle relative to the mandrel axis. The auxiliary angle ( That is, the winding angle) is controlled by the ratio of the moving speed of the dipping tank to the rotation speed of the mandrel, and the translational movement of the dipping tank is controlled by computerized electromechanical. The number of winding layers gradually increases until the designed wall thickness is reached. After winding is complete, the resin in the article is substantially cured. After curing, the core mold is released from the glass steel pipe.
2. Continuous filament winding process (continuous method): the process is that the pipe passes through a feeding station that supplies resin pre-impregnated roving, chopped fiberglass fiber and resin sand mixture in motion, and the pipe is continuously wound in the mandrel. made in progress.
3. Centrifugal casting process (belonging to the fixed length method): In this process, the cut silica gel glass fiber tube reinforcement material and sand are fed into the steel mold fixed on the bearing, and the catalyst is injected into one end of the steel mold. Saturate the resin to impregnate the reinforcing material. Under the action of centrifugal force, the resin replaces the air in the fibers and fillers, thereby producing a dense composite material without pores. Due to the action of centrifugal force, the inner wall of the tube forms a smooth, smooth and resin-rich interior. Surface layers, pipes are cured at higher temperatures. The pipe manufactured by this method is also called FRP sand pipe.
