Embodiment 1
[0024] Embodiment 1, the manufacture of the core material of the vacuum insulation panel in this embodiment includes the following steps:
[0025] A. Select rock wool fibers with a diameter of 3-5 μm, a water content of 8.0%, and a sizing agent of 0.02%, add water and stir evenly, pour the slurry into the slurry storage tank through the pouring pump, and transport the slurry to the headbox through the beating pump , diluted to a concentration of 0.5%; enter the head box to make a molding net, the thickness can be controlled at 5.0mm and then go online;
[0026] B. Shaping roll pressing: make the slurry uniform and stable, and the slurry is superimposed layer by layer;
[0027] C. Vacuum dehumidification: pump out part of the water in the vacuum process, so that the water content of the plate slurry before entering the oven is controlled at 15%; the temperature is controlled at 300 ° C, the drying time is controlled at 3 minutes, and the plate is dried and formed;
[0028] D. ...
Embodiment 2
[0029] Embodiment 2, the manufacture of the core material of the vacuum insulation panel in this embodiment includes the following steps:
[0030] A. Select rock wool fibers with a diameter of 4-7μm, a water content of 10%, and a sizing agent of 0.08%, add water and stir evenly, pour the slurry into the slurry storage tank through the slurry pump, and transport the slurry to the headbox through the beating pump , diluted to 0.8%; enter the net head box, make a molding net, the thickness can be controlled at 10mm and then go online;
[0031] B. Shaping roll pressing: make the flow slurry uniform, stable and consistent, and the slurry is superimposed layer by layer;
[0032] C. Vacuum dehumidification: pump out part of the water in the vacuum process, so that the water content of the sheet slurry before entering the oven is controlled at 55%; the temperature is controlled at 400°C, and the drying time is controlled at 4 minutes to dry the sheet;
[0033] D. Cooling: After cooli...
Embodiment 3
[0034] Embodiment 3, the manufacture of the core material of the vacuum insulation panel in this embodiment includes the following steps:
[0035] A. Select rock wool fibers with a diameter of 6-10 μm, a water content of 13%, and a sizing agent of 1.0%, add water and stir evenly, pour the slurry into the slurry storage tank through the pouring pump, and transport the slurry to the headbox through the beating pump , diluted to 1%; enter the head box, to the forming wire, the thickness can be controlled at 6mm and then go online;
[0036] B. Shaping roll pressing: make the flow slurry uniform and stable, and the slurry is superimposed layer by layer;
[0037] C. Vacuum dehumidification: remove part of the water in the vacuum process, so that the water content of the sheet slurry before entering the oven is controlled at 75%; the temperature is controlled at 450 ° C, the drying time is controlled at 4 minutes, and the sheet is dried and formed;
[0038] D. Cooling: After cooling...
