Our cast iron grinding balls can be divided into three categories including the high chromium type, medium chromium type and the low chromium type. 1. The quality index of the high chromium type The chromium content of the high chromium type product is greater than or equal to 10.0%. And the carbon content is between 1.80% and 3.20%. It is required by the national standard that the hardness of the high chromium type product must be no less than 58hrc, and that the impact value should be greater than or equal to 3.0j/cm. This type of product must go through the hot quenching and the tempering treatment to come up to the hardness. Currently at home, there are two quenching methods for this type of product including oil quenching and wind quenching. If the tested hardness of this type of product is below 54hrc, then it shows that the quenching treatment is omitted. 2.The quality index of the medium chromium type The medium chromium type cast iron grinding ball is defined as the chromium content ranging from 3.0% to 7.0%, and the carbon content coming between 1.80% and 3.20%. Its impact value should be no less than 2.0j/cm. . The national standard requires the hardness of this type of product should be greater than or equal to 47hrc. For ensuring the quality, the medium chromium type product should be processed with high temperature tempering to eliminate the casting stress. If the surface of the steel ball assumes the dark red color, it proves that the steel ball has been processed with high temperature tempering. If the surface of the steel ball still comes with the metal color, then, we can judge that the steel ball doesn’t go through the high temperature tempering treatment.

Function and usage It can set with 5 different temperature spots to do heat sealing, select the optimal heat healing temperature, and can also set the same temperature to speed up the heat sealing. Instrument structure: The structure of the heat-sealing tester is composed of 4 parts: pneumatic drive system, heat-sealing equipment, temperature adjustment system and time adjustment system. Pneumatic drive system: It includes pressure gauge, guide stick, cylinder, pneumatic valve, pressure regulating handle and so on. You can pull the pressure-regulating handle outward, rotate to the right side to adjust the heat sealing pressure to a high value, and rotate to the left side to reduce it. After setting the pressure, please press the handle to the side of mainframe to lock the air pressure. Heating-seal device It is composed of the upper and lower heat-sealing sticks, of which the upper one is connected with a cylinder. There is an insulating plate in the upper part, which can prevent heat transmit to the cylinder. The heat-sealing stick is made of aluminum, and the center is heater. There is a silica gel plate in the upper part of the lower heat-sealing stick, which can mitigate pressure impact during heat sealing. Temperature measurement system was installed at the back of the heat-sealing stick. Temperature adjustment system: The upper temperature controller controls the temperature of upper heat-sealing stick, and the rear temperature controller controls the temperature of lower heat-sealing stick. The temperature can be set at will through adjusting the button on the dial plate. Time adjustment system: Time adjustment system: The heat-sealing time can be set at will through adjusting the button on dial plate. The setting scope of time is 0.01s to 999.9h. Press the foot switch under the manual state, and the heat-sealing stick will be pressed together. Under the automatic state, the press-fitting time of upper and lower heat sealing sticks are controlled by a timer automatically, it can automatically recover later. The unit of timer is 0.1 second in general. There is time adjusting button on the panel of the timer, and the heat-sealing time can be adjusted at will.

High precision zirconia balls are available in many sizes. Zirconia balls are most commonly used as check valves in flow control applications. When subject to stress by impact, grinding, or cracking, a zirconia ball undergoes transformation toughening which stops cracks from spreading and actually makes the ball stronger in the stressed area than what it was originally.

Botanical Name - Andrographis paniculata Category - Medicinal Form - Dry Part Used - Whole Plant General Information - The whole herb is bitter in taste and is source of several diterpenoids of which a bitter water soluble lactone andrographolide is important. The plant is acrid, cooling, laxative, antipyretic, antiperiodic, anti-inflammatory, expectorant, sudorific, anthelmintic, digestive and stomachic. It is useful in burning sensation, chronic fever, malaria and intermittent fever, inflammation, cough, bronchitis, skin diseases, intestinal worm, dyspepsia, flatulence, colic, diarrhoea, dysentery, haemorrhoids and vitiated condition of pitta. The plant is often used as a substitute for Chirayita (Swertia chirayita). Phytochemicals - A number of diterpenoids and diterpenoid glycosides of similar carbon skeleton have been isolated from Andrographis, mainly the most bitter compounds among them are andrographolide, neoandrographolide, deoxyandrographolide. Other such phytochemicals amassed by the plant are 14-deoxyandro -grapholide, 14-deoxy-11,12-didehydroandrographolide, andrographiside, deoxyandrographiside, homoandrogra-pholide, andrographan, andrographon, andro-graphosterin and stigmasterol. The leaves of Andrographis contain the highest amount of andrographolide (2.39%), the most medicinally active phytochemical in the plant, while the seeds contain the lowest. Andrographolide has highly bitter taste, is colorless crystalline in appearance, and possess a "lactone function". Both growing region and seasonal changes have a strong impact on formation of the diterpene lactones. The highest concentration of the active components is found just before the plant blooms, making early fall the best time to harvest.

BST-01 Ampoule Breaking Tester Background: Ampoules serve as vital containers for pharmaceutical substances, sealed hermetically by melting the thin top with an open flame. The breaking force of the neck is pivotal, impacting both the safety of the pharmaceuticals and their clinical utility. Application: The Ampoule Breaking Strength Tester quantitatively evaluates the breaking strength of ampoules, specifically measuring the force required to rupture the neck. **Standards:** This equipment adheres to various standards such as ISO 9187, GB 2637, and YBB00332002, ensuring testing consistency and reliability. Test Process: During testing, an ampoule sample is positioned on fixtures, and the pressing head, driven by the power system at a speed of 10 mm/m, determines breaking strength using a high-precision load cell upon contact with the ampoule neck. Technical Features: The BST-01 Ampoule Breaking Strength Tester stands out with its versatility and advanced features, applicable not only in pharmaceutical and medical sectors but also in various industries. Its technical prowess, including constant displacement rate, industrial-level stability, PLC control, stepper motor precision, and safety measures, makes it indispensable for testing requirements such as compression, cap opening, syringe gliding force, puncture, and stopper penetration. The device boasts a PLC control unit, an HMI touch screen, and a precision ball-lead screw-driven stepper motor for accurate speed control. Safety features include a collecting tube for broken samples and a protective cover to prevent sample displacement during testing. Additional characteristics include: 1. Test fixtures available in various capacities (1ml, 2ml, 5ml, 10ml, and 20ml), accommodating diverse specifications. 2. Multiple fixtures for testing different materials used in medical packaging. 3. Incorporation of a limiting device and an automatic return function. 4. Adjustable test speed catering to different requirements. 5. Dot matrix microprinter for result documentation. 6. Provision of a protective cover for enhanced safety. 7. Optional RS 232 connectivity and professional software for added functionality.
