Preparation And Application On The Collecting Material Of The SiC Synthesized Process Associated Gas

The massive CO gas is produced in the silicone carbon(SiC) production (every one ton SiC with producing CO gas 1.4 ton), Presently industrial production lights it into air, both has polluted the environment and created the enormous resources wasted. This article in view of this actual situation, unifying the gas temperature, the intensity of pressure, the current capacity characteristic in the multi- heating sources SiC synthesis stove plans to develop one kind to suit to this kind of furnace gas collection material and satisfies the CO gathering of gas needing in the SiC production. This article mainly researching content including:Firstly, the substrate material choice. Chooses 6 kind of materials (ferroguinous, spreads models the cloth, anti- burns the cloth, the industrial used cloth, the glass fiber cloth and gathers the nylon)to take the substrate material, the use independently designs the gas temperature field modelling installs, research different temperature to test specimen mechanics performance influence. The result indicated that, Gathers nylon nationality to satisfy the collection gas hood material's the thermostable performance and mechanics performance, but with its direct achievement collection gas hood, but also cannot satisfy the operation requirements, therefore must develop both enhance gathers nylon cloth gas tightness and enhance its corrosion-resisting coating compound materialSecondly, the RTV mold silica gel thermostable adhesive is developed. Joins gas phase SiO₂, silicone , 2,5-two Methyl 2,5double uncle Butyl Cetane in the original formula foundation, separately studies three kind of chemical additives to the RTV mold silica gel adhesive mechanics performance and the hot weightlessness rate influence rule. The result indicated that, Gas phase SiO₂ joining has the distinct improvement to the adhesive room temperature mechanics performance, it joins the quantity lies between 2phr and 4phr the effect to be best. Simultaneously uses the epoxy resin and the acrylic acid carries on to the...
