Production method of centrifugal glass cotton-like fiber

Abstract

The invention discloses a production method of a centrifugal glass cotton-like fiber. According to the production method of the centrifugal glass cotton-like fiber, materials of quartz sands, orthoclases, limestones, glass cullet, soda ashes, borax and the like are adopted, the materials are mixed in a reasonable proportion, glass liquids can be obtained after physical and chemical reactions through kiln high-temperature melting, and short glass fiber cotton aggregates can be thrown out through high-speed centrifugal injection. Material produced through the production method of the centrifugal glass cotton-like fiber has the advantages of being small in density, low in heat conductivity, high in acoustic absorptivity, flame-resistant, frost-resistant, and not prone to decay. The material is ideal heat preservation and heat insulation material, and is mainly used in the heat insulation process of building rail structures, industrial equipment, and pipe networks, and fireproofing and the like of the buildings. The material can further used as a sound absorber which absorbs and eliminates sounds, sound-absorbing barriers, sound-absorbing wall faces and the like.

Description

technical field [0001] The invention relates to a production method of an elastic glass wool material which is flame-retardant, fire-proof, non-toxic, pollution-free, non-corroding, non-moth and frost-resistant. Background technique [0002] There is a great demand for thermal insulation materials for oil pipeline transportation and natural pipeline gas transportation, but conventional thermal insulation materials such as asbestos materials, polyurethane foam materials, and polystyrene foam materials are not fireproof, non-flame retardant, easy to weather and Qualitative disadvantages. Contents of the invention [0003] The purpose of this invention is to develop a kind of production method of the centrifugal glass wool floc fiber that uses natural ore, through rational proportioning, high-temperature melting centrifugal throwing off. [0004] The present invention aims to solve the problems that the existing thermal insulation materials are not fireproof, not flame retar...
