Embodiment 1

[0023] Such as figure 1 As shown, a double centrifugal head super-structure superfine glass fiber dry process core material production equipment. The flow rates of the molten glass 30 flowing into the two centrifugal discs 40 from the two drain plates 20 respectively are 120kg / h, and the superfine glass fiber cotton 31 is produced by the centrifugal blowing method, and the average diameter of the fibers is 3.2 μm. During the falling process of the glass fiber cotton 31, the annular airflow 50 below the centrifugal head cuts ultra-fine glass fibers, the airflow cutting angle is 45°, the air pressure is 0.3MPa, and the fiber aspect ratio is 2500. The cut centrifugal glass fiber cotton is attracted by the drawing wind, its own gravity and the negative pressure wind, and falls down to the cotton collector through the Venturi tube, and the superlayer structure of double centrifugal heads is prepared by superposition of two centrifugal heads. Ultrafine glass fiber dry-process core ...

Embodiment 2

[0025] Such as figure 2 Shown, a kind of superfine glass fiber dry-process core material production equipment with super-layer structure of three centrifugal heads. The flow rates of the molten glass 30 flowing into the three centrifugal discs 40 from the three drain plates 20 are 80 kg / h respectively, and the superfine glass fiber cotton 31 is produced by the centrifugal blowing method, and the average diameter of the fibers is 2.8 μm. When the glass fiber cotton 31 is falling, the annular airflow 50 below the centrifugal head cuts ultra-fine glass fibers, the cutting angle of the airflow is 45°, the flow rate of the airflow is 0.5MPa, and the fiber aspect ratio is 2000. The cut centrifugal glass fiber cotton is attracted by the drawing wind, its own gravity and the negative pressure wind, and falls down to the cotton collector through the Venturi tube, and the superlayer structure of double centrifugal heads is prepared by superposition of three centrifugal heads. Ultrafin...

Abstract

The invention discloses equipment for producing a superfine glass fiber dry-process core material with multiple centrifugal heads and an ultra-layer structure. The equipment is composed of a kiln, a channel, a leaking board, a centrifugal wire-drawing system, an annular cutter, a Venturi tube, a fiber collector, and a negative pressure wind turbine from top to bottom. The prepared glass fibers are evenly distributed, the distance between two neighbored layers is 10 to 60 [mu]m, and the heat conductivity coefficient of the core material is 0.015 to 0.03 W / (m.K) (20 DEG C). The equipment has the advantages of simple technology process, stable technology, and easiness for industrial production.

Description

technical field [0001] The invention relates to a glass fiber core material production equipment, in particular to a multi-centrifugal head super-layer structure superfine glass fiber dry process core material production equipment. Background technique [0002] Vacuum insulation panels are based on the principle of vacuum insulation. High-efficiency insulation is achieved by maximizing the vacuum inside the panel and filling porous materials with low thermal conductivity. It is widely used in refrigerators, freezers, refrigerated containers, building insulation and other fields. It is the current insulation The material with the best thermal insulation properties. Vacuum insulation panels are mainly composed of core materials, packaging membrane materials and gas adsorption materials. The core material is the support body of vacuum insulation panels, which has the characteristics of high porosity and low thermal conductivity, and is the core structure of vacuum insulation pa...
