who knows the technology of fireproofing material?
1, dealing mould, scrape and clean the thick liquid on the surface of mould with tin-coated steel scraper blade or plaster tool. 2, adjust laminator, according to the thickness of fireproof?panel, adjust each roller, keep them parallel. 3, ingredient, according to the requirements of recipe, stir the raw materials uniform with agitator. (usually we should add bittern firstly, stir it with modifying agent for 5 minutes, then add filler and stir for 2-3 minutes, finally add grogs and stir it to uniform) note: the stirring speed should be kept in 60-80 r/min. 4, place the cloth, place a layer of non-woven fabric and two layers of glass fiber fabric (mechanical spread fabric). 5, flitch, place the materials after compounding and stirring into stop gauge of laminator, then you can start up and produce continuously, it's finished product after finishing. note: the distance between two templates is 2-4mm.
1, Foam insulation board,it's the foam insulation board material made by inorganic ceramic material through high temperature roasting, and is called for short as ceramic insulation plate. 2, composite cement foaming insulation board is made by cement,fly-ash,silica fume and other main materials and it's a kind of hole-closed?lightweight hydrophobic insulation board made by the technologies of foam,maintenance,cutting processing. 3, gypsum foam thermal insulation board is inorganic thermal insulation board that takes industrial by-product gypsum as the main raw material, modify the gypsum through physic modified principle, then foam, casting and cutting through chemical foam principle. 4, aerated concrete panel is made by lightweight material,silicious material, foaming?agent and other raw materials and it's a kind of lightweight concrete plate material made by the high pressure steam of manufacturing technique. 5, rock wool board is made by natural igneous rock and other main materials, and it's a kind of plate with thermosetting resin as binder made through melting in high temperature and centrifugation.
First: Firstly, you should produce the recipe and prepare the raw materials, for example, if you prepare to produce 1 ton, you should compute the recipe sheet of 1 ton producing; check whether the raw materials are complete; second: make the color and filler thick liquid; add water in order and proper auxiliary in a low speed, then put color and filler (generally we should firstly add something with large oil absorption), wash the meachine after putting the powder. Then seperate them for about 20 miutes in a high speed, until the fineness is qualified; of course, if you need sander, i think you only need sino-soviet differential powder material and non-obvious particles. Third: Paint mixing period: after making the color and filler thick liquid, reduce the roll speed into about 600 roll per minute, add emulsion and proper auxiliary, finally adjust PH and viscosity.
