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.

As the iron core of the transformer, generally, 0.35mm thick cold 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.

Silicon steel is a traditional magnetic material mainly for 50Hz to 1000Hz electronic and electrical applications. The toroidal core is one of the main products of Transmart Industrial. Our silicon steel core series has many styles to meet the diversified needs of customers. We manufacture various type of cores in silicon steels, such as Current Sensor Cores, silicon steel transformer core, Instrument Transformer Cores, Torodal cores, C-cores, Unicore etc. Transmart Industrial carries out strict quality monitoring and cost control on each production link of toroidal core, from raw material purchase, production and processing and finished product delivery to packaging and transportation. This effectively ensures the product has better quality and more favorable price than other products in the industry. Discover extra info at https://www.transmart.net/.

The annealing temperature of iron-based amorphous alloy is lower than that of silicon steel, and the energy consumption is small, and the iron-based amorphous alloy magnetic core is generally manufactured by special manufacturers. Silicon steel magnetic cores are generally manufactured by transformer manufacturers. According to the above comparison, as long as it reaches a certain production scale, iron-based amorphous alloy will replace some silicon steel markets in electronic transformers within the power frequency range. In the medium frequency range of 400Hz to 10kHz, even if new silicon steel varieties appear, iron-based amorphous alloy will still replace most silicon steel markets with a thickness of less than 0.15mm.

After surface insulation treatment, the magnetic core is evenly mixed with the binder, pressed and annealed. There are basically three ways to obtain nanocrystalline powder: amorphous strip crushing after annealing and crystallization, mechanical alloying and molten alloy atomization. At present, mechanical alloying is still in the laboratory research stage. A few companies produce amorphous strip crystallization in small quantities in China, but it is unable to expand the market due to cost reasons. Compared with other methods, molten alloy atomization method has high efficiency and low cost. Its disadvantage is that the amorphous content of the powder is low and the loss is high.

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: It is strictly forbidden to use the Computerized Universal Tensile Strength Testing Machine price for overload and super speed. It is strictly forbidden to hit the lifting screw with hard objects and put on the lubricating oil on time. When mechanically replacing the V-belt, pay attention to the position of the hand to prevent pinching the finger. The transmission part must be covered with a protective cover.

ASTM D4060 Taber Abrasion Tester Uses and Factors to Be Considered: Taber Abrasion is used for measuring the wear resistance of organic coatings applied flat, rigid test samples. ASTM D1044 is used for transparent plastic materials to evaluate their capacity to maintain their optical properties, upon typical, wear to be expected while in service. Abrasion resistance to Taber Abrasion is usually measured as a weight or a coating thickness loss after a given number of cycles. Each arm, by default, is loaded to apply a 250 g. pressure on each wheel. Depending on the product/specification used, this weight can be increased to 500g or 1000g. The abrading wheels are available in different grit for a more or less abrasive action.

Gauge length and tension speed presettable; Able to set pre-tensile force; Many kinds of clamp are selectable according to requirements test standards, including pneumatic clamps. Textile fabric, such as bedsheets, clothes, etc., a lot of them will lose color after washing, some products fade seriously, even after washing many times, there will still be discolored. Test Preparation before Color Fastness to Washing. What test standards are there? Color fastness to washing is one of the common test items for textile dyeing fastness, which is mainly used to test the fastness of fabric clothing and home textile products after one or more times to simulate the dyeing after household washing and commercial washing. There are three common standard: AATCC 61, ISO 105 C06, GB/T 3921. Discover additional details at gesterinstruments.com.
