Our isostatic graphite and Molded Graphite were tested at the National Electrical Carbon Products Quality Supervision and Inspection Center. The main physical and chemical performance index as follows: the compressive strength--125 mpa, shore hardness -- 65 degrees, resistivity --12 mu Ω m. At the same time, the 10μm,8μm,6μm,4μm products have already began Large-scale production,.and unanimously acknowledged by customers. The 2μm,1μm graphite products are under trial. Our company high quality of isostatic pressing special graphite yield above 90%, far ahead of industry the yield of 70%, the first in the country.
Knife-type gate valve has the advantages of simple and compact structure, reasonable design, light material, reliable sealing, light and flexible operation, small size, smooth passage, small flow resistance, light weight, easy installation and easy disassembly. 2.5MPa, the use of temperature -29-550 ℃ under normal circumstances. Knife Gate Valve: It is suitable for all kinds of powder, granule and slurry fluid in the general petrochemical and other food industries, cement papermaking, environmental protection, etc. The gate of the knife-type gate valve has the function of cutting to scrape off the adhesion on the sealing surface Objects, automatic removal of debris, stainless steel gate to prevent corrosion caused by leakage seal. Knife gate valve: Features 1, short structure length, save material, the piping system can greatly reduce the overall weight 2, take up less effective space, can effectively support the strength of the pipeline, reducing the possibility of pipeline vibration 3, the gate Selection of austenitic stainless steel, corrosion resistance greatly improved, which can effectively prevent the leakage caused by the gate seal leaks 4, the sealing filler with flexible PTFE, reliable sealing, light and flexible operation 5, the gate with the knife function, Can effectively block all kinds of debris in the media Knife gate valve Connection: flange (4) on the folder (7) Knife gate valve Transmission: hand wheel, bevel gear (5), sprocket (4) (L) , Pneumatic (6), Electric (9), Hydraulic (2), Electrohydraulic (2), Manual Pneumatic Switching (6S) Knife Gate Valve Sealing Surface Material: Alloy Steel (H) Soft Seals (X) Carbide (Y) Valve Material (W) Installation and use of knife gate valve: 1. Check the valve cavity and sealing surface and other parts before installation, do not allow dirt or grit to be attached; 2. The bolts of connecting parts should be evenly tightened; 3. Check the packing section Bit requires compression, both to ensure that the packing seal, but also to ensure that the gate open flexible; 4. Before installing the valve, the user must check the valve model, connection size and pay attention to the flow of media to ensure consistency with the valve requirements; 5. Users When installing the valve, the valve must be reserved space for driving; 6. Drive wiring according to the road map; 7. Knife gate valve must be regularly maintained, shall not be free to crash and squeeze, so as not to affect the seal.
EDM graphite, also known as graphite block for EDM, is a new type of material, which is now more and more widely used in the precision mold processing industry. At present, in mold processing plants in developed European countries, more than 90% of mold processing electrode materials are graphite. Copper, the once dominant electrode material, has almost lost its advantages compared with graphite electrodes.
