2023-02-221. Preparation before work: Wear a hood, raindrops, glue gloves, safety helmets, glue gloves must be allowed to simply water, sore water, and allow them to be allowed to work; Add 109 sodium hydroxide solution water solution; turn on the anode rod back cover, use both hands to gently display the graphite anode board from the anode rod, and migrate to the graphite cleaning slot soak for 30 minutes.2. Actual operation: Remove the graphite anode plate that soaks soaked for thirty minutes from the soaking solution, flatten the electroplating equipment on the wooden frame, and use 240#-320#water matte paper to clean the surface layer of the graphite anode plate. , Hold the positive film with one hand, gently press the policing paper with the other hand, and drink water to clean it until the stains are eliminated, and then use the water matte paper to remove the anode oxidation and touch the guidance. After that, clean all the liquid cold water, and check whether there is dirt on the surfac
2023-02-22What are the effects of graphite products? The scope of graphite applicable is to produce artworks that can manufacture fire insulation materials and high -temperature raw materials. In recent years, fire prevention insulation and insulation materials have not been widely used in industrialized production. So what are the efficacy of graphite products? Beijing graphite pot manufacturers summarize the scope and efficacy of graphite products.Industries such as national defense and safety have been widely used, and graphite products have long been widely used in metallurgical industry, chemical enterprises, petrochemical equipment machinery equipment, high -energy physics, aerospace, electronic components, etc. High -purity graphite can be used to manufacture insulation bricks, tongs, constantly built -in powder, molding cores, mold casting, detergent and high temperature resistance, which is closely linked to the steelmaking industry.
2023-02-22What are the characteristics of pre -immersed graphite carbon plates, pre -immersed graphite carbon plates, high -quality graphite carbon raw materials, and organic chemical complexes with strong alkali resistance. It is made of compression, vacuum pump pre -immersing, and high -temperature thermal treatment methods. It has an extraordinary acid resistance and thermal resistance. It is the idealized lining raw material for machinery and equipment such as ammonium sulfate reflection slot and ammonium sulfate storage slot in the chemical manufacturing industry. Category of non -transparent graphite. Pre -immersed graphite with anti -corrosive coatings to block its surface and internal pores, and then carry out the heat treatment process to make the epoxy resin dry. Compared with graphite, the impact toughness is improved, and the heat transfer performance will not change. Different from the pre -immersed epoxy resin, there are different types of phenolic resin thermal immersion zinc gra
2023-02-22The crushing of graphite blocks can be divided into three items, do you know? Let's take a look at it together!1. Pre -fragmentation (or crushing): This also refers to the crushing of block -shaped graphite block raw materials after entering the factory. Generally, it refers to crushing the block of the block of 200mm to 50 ~ 70mm. EssenceSecond, medium crushing: This also refers to the granularity of graphite block raw materials after forging to the particle size necessary for the seasoning. Generally, the block degree of up and down 50mm after the forging is crushed to 1 ~ 20mm.Third, fine grinding (or grinding): It is grinding part of the raw material of graphite blocks to 0.15mm or 0.075mm particle size below. Every time it goes through, the granularity of the raw materials has become smaller. The larger diameter of the large raw material before crushing is the ratio of the diameter of the larger block of the raw material after crushing, which is called a crushing ratio.
2023-02-22The harm of the shape of the graphite boat to the surface layer of the surface layer will use the new graphite boat and the use of the old graphite boat for more than three years to saturate the coating on the surface layer of the PECVD surface. The flat surface of the new graphite boat is good, and the graphite boat has the same conductivity. The plastic membrane molecular formula can be uniformly accumulated on the surface of the single crystal silicon wafer, and the uniformity between the pieces is higher.After the new graphite boat is saturated, there are still some plasma accumulated on the graphite boat when the accumulation is accumulated. When the number of running times is less than thirty times, as the number of running times increases, the plasma accumulated on the graphite boat decreases. Essence After the number of running times exceeds thirty times, as the number of uses increases, the inner wall of the graphite tape and the single crystal silicon tablets touch the plast
2023-02-22Graphite is a raw material that is stable in physical properties, anti -corrosion, and drugs such as acid, alkali and other drugs that is not easy to produce reflected. It is common in the production of processed graphite board, graphite board, graphite anode board, graphite bipolar tablets and other products. Petrochemical equipment, mechanical engineering, electronic device industry chain, China nuclear industry and national defense security are all used in areasBecause graphite can be used to manufacture refractory insulation materials, conductive raw materials, metal composite materials, lubricating liquid, heat -resistant rubber seals, corrosion -resistant raw materials, insulation materials, raw materials, wear resistance and radiation -proof materials, etc.1. Fire. Graphite refractory insulation materials are mainly casting raw materials, magnesium carbon bricks and aluminum graphite refractory insulation materials.2. conductivity. There are also television series graphics card
