A kind of online dry production system and method of glass wool vacuum insulation board core material

Abstract

The invention discloses an online dry-process production system of a glass wool vacuum insulation board core material, the online dry-process production system comprises a smelting furnace, a centrifuge, a cotton collecting machine, a heating furnace and a shaping device. The shaping device adopts upper and lower chain plates to cooperate to form a pressing gap. A glass wool layer heated by the heating furnace at high temperature is pressed in the pressing gap, and can be continuously hot-pressed in the process of transmission. The present invention also provides a production method based on the above production system. Compared with the prior art, online continuous production is realized, production efficiency is high, equipment cost is low, and the obtained glass wool core material has stable structure and good insulation effect.

Description

technical field [0001] The invention relates to the manufacturing technology of glass wool, in particular to an online dry production system and method of glass wool vacuum heat insulation panel core material. Background technique [0002] Vacuum insulation panel is a new type of high-efficiency thermal insulation material that combines the principle of vacuum insulation with traditional thermal insulation materials. It is composed of membrane materials, core materials and getter materials. The gas is removed through internal vacuum treatment, thereby eliminating The heat transfer path is isolated from heat conduction, so as to achieve the purpose of heat preservation, heat insulation and energy saving. Vacuum insulation panels are widely used in refrigerators, incubators, building walls, refrigerated containers and other fields. [0003] The core material is the core of the vacuum insulation panel, and it is mostly made of materials with high porosity, connected pores and ...

AI Technical Summary

Problems solved by technology

However, because most of the current hot-pressing and shaping equipment is formed by heating and pressing the upper and lower molds, limited by the size of the mold, the glass wool needs to be cut and hot-pressed off-line, which cannot achieve continuous online operation; Uniform, which affects its thermal insulation performance

This has resulted in discontinuous dry process operations, a lot of labor, poor controllability, low efficiency, high cost, and it is difficult for practical production and application
