We know that the actual transformer always works in AC state, and the power loss is not only on the resistance of the coil, but also in the iron core magnetized by alternating current. Usually, the power loss in the iron core is called “iron loss”. The iron loss is caused by two reasons, one is “hysteresis loss” and the other is “eddy current loss”. Hysteresis loss is the iron loss caused by the hysteresis phenomenon in the magnetization process of the iron core. The size of this loss is directly proportional to the area surrounded by the hysteresis loop of the material. The hysteresis loop of silicon steel is narrow, and the hysteresis loss of transformer core made of silicon steel is small, which can greatly reduce its heating degree.

Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of steel with silicon (silicon is also called silicon), and its silicon content is 0.8 ~ 4.8%. The reason why silicon steel is used as the iron core of transformer is that silicon steel itself is a magnetic material with strong magnetic conductivity. In the energized coil, it can produce large magnetic induction intensity, which can reduce the volume of transformer. rolled silicon steel sheet is selected. It is cut into long pieces according to the size of the required iron core, and then overlapped into “day” shape or “mouth” shape. In principle, in order to reduce eddy current, the thinner the silicon steel sheet, the narrower the spliced strip, and the better the effect. This not only reduces the eddy current loss and temperature rise, but also saves the material of silicon steel sheet. But in fact, when making silicon steel sheet iron core. Not only from the above favorable factors, because making the iron core in that way will greatly increase the working hours and reduce the effective section of the iron core. Therefore, when making transformer iron core with silicon steel sheet, we should start from the specific situation, weigh the advantages and disadvantages and choose the best size.

Amorphous nanocrystalline alloys are competing with soft ferrite in the field of medium and high frequency. In 10kHz to 50KHz electronic transformer, the working magnetic flux density of iron-based nanocrystalline alloy can reach 0.5T and the loss P0.05 5 / 20K ≤ 25W / kg, so it has obvious advantages in high-power electronic transformer. In 50 kHz to 100 kHz electronic transformer, the loss of iron-based nanocrystalline alloy is P0.05 2 / 100k is 30 ~ 75W / kg, Fe based amorphous alloy P0.05 2 / 100k is 30W / kg, which can replace some ferrite markets.

On the one hand, it can isolate eddy current, and the data is suitable for higher frequencies; On the other hand, due to the gap effect between particles, the data has low permeability and constant permeability; Because the particle size is small, there is basically no skin phenomenon, and the change of permeability with frequency is relatively stable; Moreover, the powder core can be prepared into special-shaped parts of various shapes for different fields; Finally, the damaged strip in industry can be crushed into magnetic powder, and then made into magnetic powder core, which can reduce the loss and improve the use value of data. The magnetoelectric properties of magnetic particle core mainly depend on the permeability of powder material, size and shape of powder, filling coefficient, content of insulating medium, forming pressure and heat treatment process.

Intermediate content of 10-12%, mainly used for powder coating treatment and increase capacity flow. In the grinding pigment (filling) process of producing pigments and inks, a metering coupling agent can be directly input, which can improve the dispersibility of the pigment or filler, shorten the grinding time, increase fineness, brightness, and reduce viscosity. Atactic polypropylene is effectively solve the problem of high filling system debris, improve the toughness of products, can replace the use of carrier, but also can replace the use of lubrication. Atactic polypropylene is used in filler masterbatch, etc Discover extra information at sainuowax.com.

The internal and external lubrication is insufficient, the melt viscosity is large, the plasticizing torque is large, and the melt wall sticking phenomenon is serious. There is a yellow decomposition line on the material surface, the surface smoothness is poor, and the mechanical properties of the product are reduced: the internal and external lubrication is excessive, the plasticizing torque is small, and the melt plasticization is obviously insufficient. Although the product has good smoothness, the pressure point adhesion is poor, which seriously affects the mechanical properties of the product.

High quality synthetic blood penetration tester factory?

Application of Universal Testing Machine: This types of tensile testing machines is designed for conducting tensile, compression, bending, shearing, bonding strength, peeling, tearing and other tests for shoes, rubber, plastic, leather, metal, nylon line, fabric, paper, aviation, packaging, construction, petrifaction, electrician, vehicle and other materials. It is a basic equipment of quality control, receiving inspection, physical test, mechanics research, material development.

Correct use of computerized universal testing machine: Make sure all wiring is correct before the tensile testing machine is operated and preheat for at least 15 minutes to package the stability of the sensor. According to the test, the position of the upper and lower limit blocks is reasonably set to prevent the instrument from running over the stroke and causing damage to the fixture and the sample. When pressing the fast up button or the fast down button, do not put your hand between the moving beam and the fixed specimen, fixture or test device to avoid injury.

Testing to ASTM D4060 involves mounting a flat specimen to a turntable that rotates horizontally at a fixed speed. Two arms, each supporting an abrading wheel, are then lowered so that each wheel touches the surface. Before starting the test, a “suction arm” is lowered between the wheels to remove the abraded material from the sample’s surface. The turntable then starts rotating forcing rub-wear action of the wheels against the sample’s surface for the specified number of cycles or until a given mass of coating has been lost or until the wheels start exposing the substrate.

The principle of testing that you should know: Stitch the sample with one or two pieces of specified multi-fiber adjacent fabric, which is placed in soap solution or other washing solution, mechanically stirred at the specified time and temperature, cleaned and dried. Taking the original sample as the reference sample, assess the discoloration of the sample by the left gray scale, and then assess the color stain of the adjacent fabric by the right gray scale.
