Embodiment

[0012] Example: The preparation of the glass wool core material includes a beating section, a pulp mixing section, a forming section, a drying section and a finished product cutting section, wherein the beating method in the beating section includes the following steps:

[0013] (1) Accurately weigh 125±0.5KG of glass fiber. The glass fiber in this example is Daqing Huoyan cotton. The diameter of the glass fiber is 3.05-4.2 μm. Stack them according to the model. Pay attention to the cleanliness of the raw materials to prevent the mixing of impurities;

[0014] (2) Add half of the weighed raw material weight into the beating bucket, and then add 2.5 to 3 tons of backwater into the beating bucket;

[0015] (3) Add 200-300ml of sulfuric acid into the beating barrel to adjust the pH value to 2.5-3.0;

[0016] (4) Perform beating, the beating time is set to 120-250 seconds, and the stirring speed of the beater is 500 rpm;

[0017] (5) Put the remaining raw materials into another ...

Abstract

The invention discloses a forming method of a glass wool core material, which comprises the following steps: (1) tightening a forming net, and starting a motor so that the forming net can slowly drive at uniform speed; (2) when the temperature of a baking oven achieves the preset temperature, starting feeding the pulp for production, and regulating the pH value of a forming groove at 3.0-3.1; (3) adjusting the forming net and the rotation speed of the baking oven according to the requirements of the art work sheet, and adjusting a frequency converter for controlling the rotation speed to 3-10Hz; (4) adjusting vacuum valves to control the vacuum pressures, wherein the pressure of the 1# valve is controlled at 0.005-0.015MPa, the pressure of the 2# valve is controlled at 0.035-0.045MPa, and the pressure of the 3# valve is controlled at 0.06MPa; (5) adjusting the forming rolling shaft to control the wet-state thickness of the core material; and (6) adjusting compression rollers to control the fixed quantity of the core material. The glass wool core material, which is prepared by the forming method in cooperation with other technical steps, has the advantages of uniform thickness, favorable elasticity, high stability and favorable heat-insulation effect.

Description

technical field [0001] The invention relates to a method for preparing a glass wool core material, in particular to a molding method therein. Background technique [0002] Vacuum insulation panels are one of the vacuum insulation materials. The vacuum insulation panels currently on the market are mainly composed of filled core materials and vacuum protection surfaces. Vacuum insulation panels are mainly used for thermal insulation, such as refrigerators, freezers, electric water heaters, vending machines, refrigerated containers, building wall insulation, and LNG storage and transportation. The core material for vacuum insulation panels is mainly made of glass fiber or glass fiber mixed with some other substances through the steps of beating, pulping, molding, drying, and finished product cutting. Due to the different specific preparation methods of the core materials, the quality of the produced products cannot be uniform, and the best thermal insulation effect cannot be a...
