2023-05-24(1) Taking natural scales graphite as raw materials, use Hummers legal oxygen graphite, and use thermal peeling into graphene, or use ultrasonic dispersion to divert into graphene, and then chemically restore into graphene. Use SEM, TEM, HRTEM, XRD, and RAMAN systems to examine the appearance and structure of graphene.(2) Taking graphene as the basis, titanate tetraododes as titanium sources. First, the solution-water thermal legal system is used to prepare titanium dioxide/graphene nano-composite materials. Use XRD, SEM, TEM, and RAMAN to characterize the crystal structure, granular appearance and chemical composition of titanium dioxide/graphene nano -composite materials. The results show that the synthetic titanium dioxide nanocrystal is a sharp titanium structure, the crystalline condition is good, titanium dioxide and graphite The composite effect is better. The photocatalytic performance of nano crystals was studied, and the results showed that titanium dioxide/graphene catalyti
2023-05-24Features: The surface can be combined with other materials such as metal, plastic, non -drying, etc. to meet more design functions and needs.Low thermal resistance: The heat resistance is 40%lower than that of aluminum, 20%lower than copper.Light weight: weight is 25%lighter than aluminum, 75%lighter than copper.High -conductive coefficient: Graphite radiator can be smoothly attached to any plane and curved surface, and can cut any form of cutting according to the needs of customers.The artificial graphite film is widely used in important emerging industries such as new energy and energy -saving transformation with its high thermal heating high reliability, lightness, easy processing, and environmental protection. There are huge application prospects in the fields of electronic technology such as LED. Of course, this type of product is widely used in smartphones, such as Apple mobile phones and Samsung phones. At the same time, the equipment in the laptop, handheld equipment, and comm
2023-05-23Graphite radiator (3K-SBP) is a brand new heat-conducting heat dissipation material with unique grain orientation, which is evenly conducted in two directions. Improve the performance of consumer electronics. The product is uniformly dissipated while providing heat isolation in terms of thickness. The molecular structure diagram of the thermal graphite sheet is as follows:The unique combination of heat dissipation and thermal insulation performance of graphite heat conductive solutions allows heat -conducting graphite to become an outstanding material option for heat management solutions. The thermal graphite plane has the ultra-high thermal conductivity within the range of 150-1500 W/m-K.The chemical composition of Thermal Flexible Graphite Sheet is mainly a single carbon (C) element. It is a natural element mineral. The film polymer compound can obtain a graphized thin film under high temperature and high pressure because the carbon element is non -metal. Elements, but there is a co
2023-05-23Machining artificial graphite into the shape of the required, and then use resin immersion and solidification, which is made of non -transparent graphite products for thermal exchange. For chemical industry. include:(1) Block hole heat exchanger;(2) radial heat exchanger;(3) Membrane heat exchanger;(4) Tube heat exchanger.
2023-05-23It is mainly based on petroleum coke and needle -shaped coke, and coal pettea is used as a binding agent. The heating conductor can be divided into ordinary power, high power and ultra -high power according to its quality indicators. Graphite electrodes include:(1) Ordinary power graphite electrode. Allowing a graphite electrode with a current density of less than 17A/cm 2, it is mainly used for ordinary power furnaces such as steelmaking, silicon, and yellow phosphorus.(2) Antioxidant coating graphite electrode. A graphite electrode with a layer of antioxidant protective layer is coated on the surface, forming a protective layer that can conduct electricity and high temperature resistant oxidation, and reduce the electrode consumption during steelmaking.(3) High -power graphite electrode. Allowing a graphite electrode with a current density of 18 to 25A/cm 2, it is mainly used for high -power arc furnaces for steelmaking.(4) Ultra -high -power graphite electrode. Allows the use of gr
2023-05-22Crystal structureNatural graphite: Crystal development is relatively complete, the graphization of scales graphite is more than 98%, and the graphitization degree of natural micro -crystal graphite is usually below 93%.Artificial graphite: The degree of crystal development depends on raw materials and thermal treatment temperature. Generally speaking, the higher the thermal treatment temperature, the higher the graphite. The artificial graphite produced by industrial production is usually less than 90%.Organizational structureNatural scale graphite: It is a single crystal, which is simpler in the tissue structure. There are only shortcomings in crystalline learning (such as defects, wrong positions, errors, etc.). The grains of natural micro -crystal graphite are small, the clutter between the grains is arranged, and there is a hole after the removal of impurities, which shows the same sex in the macro.Artificial Graphite: It can be regarded as a variety of materials, including graphi
