That is a separate sprue dipping, 4 cylinder block foam pattern (with the runner) and the upper and lower combined into two runner looks like a mechanical hand dipping (looks like the combination of buoyancy in the coatings suffered about 1400N) j. After dipping paint combinations look like, must be dried. Look like in the dry mix operation, to strictly control the oven temperature, the best control (50 ± 5) ℃ between. If the temperature is low, longer working hours would reduce the labor productivity; if the temperature is too high will cause deformation of the bubble to swell. The specific criteria should be dry from time to time between the before and after weighing the two, the quality is not there is a greater change, that it is the dried (interval 2h, look like the quality of the portfolio changes less than 1g, to think that drying a). 7 modeling processes and solutions of common defects for the horizontal vibration table vibration table, vibration source is the motor and 4 eccentric composition, at the upper and lower two-axis all arranged in the table on one side, a total of four eccentric gear position With the gear in order to increase the exciting force increased, the total exciting force of about 40kN. In the sand box at the bottom of the fixed bracket installed four high-pressure air to enhance the effect of tap. Casting process of deformation is easier in the shape of one of the defects produced. Real look like less rigid foam casting, in a smaller stress is prone to deformation under the action. Mainly through the appearance of strength between mold resin film layer and the surface paint on the painted shell to provide a link. Gelatinous layer between the mold pieces combined firm, to prevent the paint or sand into the gap caused by sand mold chip defects. However, if excessive use of adhesive glue will lead to increased gas evolution, affecting the quality of castings. When the coating layer to form buffer appearance of sand on the force, but also the hot liquid metal that can withstand the impact and static pressure to prevent infiltration of liquid metal in the sand to improve the surface quality of castings. However, if the coating thickness is large (more than 2mln),<a href="http://www.stivaliuggitalia.org" target="_blank" class="postlink">stivali ugg</a>, coating layer permeability and absorption slag will fall, affecting the quality of castings. Therefore, the unilateral glial layer and paint the shell to rely on to solve the deformation of the casting defects is difficult. But also from the ways and pumping sand filling up the degree of negative pressure into account. Sand is used when modeling a single dry sand, particle size of 0.6-0.8mln. Fill in the sand box at the bottom of the first place 100-150mln thick mat of sand and let people mix look like, using artificial means or by supporting fixture to hold of the sprue, the rain-type sand to the 150-200mln thick, start tap Taiwan, 40 combinations look like tap and fixed. Further 150,200 rain-style coffee thick sand, vibration tap. Edge after edge tap sand until the sand box fill up. Tap, the cast-like surface hardness of up to 60-7O, vacuum pumping up to 90 the hardness (surface hardness readings.) Finally, under the conditions of pumping vacuum casting, pressure control in a 79993.2 a 39996.6Pa range, negative pressure should be kept in the 10s, after pouring over. Sand layer above, and gradually tap and vacuum pumping means, and help prevent deformation of casting. 8 Mold Casting Mold Casting Production waste gas treatment, the polystyrene foam pattern occurred gasification, produce large amounts of toxic gases (mostly benzene, toluene, styrene). Catalytic combustion is an effective method to treat organic waste. Under normal circumstances, when the exhaust gas through the catalyst, only in the 300-400oC can be achieved less complete combustion. One catalyst is used as carrier of porous ceramic materials. When pouring the stage collected from toxic and harmful gas composition through the surface of the catalyst,<a href="http://www.monclerjackens.net" target="_blank" class="postlink">Moncler online</a>, the catalyst surface can absorb the active ingredients of these toxic ingredients, reduce the activation energy they burn. Which occurs at lower temperatures complete conversion. Through the production of practical application, the program investment is small,<a href="http://www.monclerjackens.net" target="_blank" class="postlink">moncler outlet</a>, clean effect. Reference +8 from 28 to 30, by the National Science and Technology, Science and Technology Department of Jiangsu Province, south of Beijing University of Aeronautics and j jointly organized by the National type dealt Act and to promote EPC technology i made a spot in a large international conference in Nanjing Hotel grand opening.
