Abstract
The invention discloses a method for preparing a hollow glass bead by using a glass powder process, comprising the following steps of: proportioning, melting, crushing, hollow balling, collecting, screening and inspecting. The crushing step is operated as follows: molten glass is sprayed out through a porous nozzle under the action of high-pressure gas of over 2MPa to form downwards splashed molten glass drops, the molten glass drops runs into the surface of a high-speed rotating rotary drum in the falling process, circulating water is introduced to the rotary drum to cool the molten glass drops, and molten glass drops form glass particles with particle sizes of 1-100mm under the combined actions of gravity, centrifugal force and splashing force. The method has the innovation point that a novel centrifugal crushing process is used for replacing the water crushing, drying, coarse crushing and fine crushing processes in the original production process, and therefore, the production process is simplified, the energy consumption is reduced, equipment and personnel costs are reduced, and operation and quality are easy to control; and by using the method, the production cost can be reduced by 14-20%, and the compression strength is improved by 4.8-15%.
Description
Technical field:
The present invention relates to the production technique of hollow glass micropearl, in particular, relate to the method that a kind of glass powder legal system is equipped with hollow glass micropearl.
Background technology:
Hollow glass micropearl is a kind of hollow, include the spherical glass powder of one or more rare gas elementes, size distribution from several microns to hundreds of micron.Particular structure makes it to possess that density is low, good fluidity, thermal conductivity is low, ultimate compression strength is high, chemicalstability is good characteristics, has been applied in military, civilian and high-tech areas such as aerospace, oil production, deep-sea floating body material, emulsion [explosive, high-grade insulating materials, body of wall heat-insulating fire-proofing material at present.
The preparation method of hollow glass micropearl mainly contains desiccant gel method, sessile drop method and glass powder method; Because preparing method's restriction; The hollow glass micropearl intensity of desiccant gel method and sessile drop method preparation is all lower, and the glass powder method is generally adopted in the production of high-end hollow glass micropearl.
Glass powder method production process mainly is: 1 batching → 2 fusings → 3 water are broken → 4 oven dry → 5 coarse crushings → 6 are in small, broken bits → 7 hollow nodularizations → 8 collect → 9 screenings → 10 checks, and the batching fusing is to prepare dissimilar products as requested, hollow nodularization be formed product must be through process; Be comparatively ripe at present and stable technology; To consider from industrialized angle, 3 water are broken → and the operating process in small, broken bits of 4 oven dry → 5 coarse crushings → 6 is loaded down with trivial details relatively, complex manufacturing; Equipment is many; Energy consumption is high, and efficient is low, increases the uncontrollability of product.This segment process detailed process is: at first will melt good glass metal and pour slowly from melting furnaces that through the shrend chilling glass metal to be become glass in the tank that feeds cold water broken into; Pull it out oven dry and the glass that it is broken for below 2 millimeters is broken then through roll crusher; Standard compliant glass is broken to be sent in the airflow milling, and pulverizing is 1～100 micron a glass powder.In the shattering process since the introducing of impurity such as iron cause the glass microballon composition change, reduced the hollow glass micropearl performance index, bring noise and dust pollution simultaneously; Because the input of the energy and human cost has strengthened production cost, because the increase of control node has increased difficulty also for the quality control of hollow glass micropearl.
Summary of the invention
The object of the present invention is to provide a kind of glass powder legal system that is easy to operate and control to be equipped with the method for hollow glass micropearl, production cost reduces by 14～20%, and ultimate compression strength improves 4.8～15%.
The objective of the invention is through pulverising step among the preparation technology being improved as follows realization; A kind of glass powder legal system is equipped with the method for hollow glass micropearl; Comprise batching, fusion, pulverizing, hollow nodularization, collection, screening, check; Innovative point of the present invention be with water in the existing production technique broken → oven dry → coarse crushing → process in small, broken bits is reduced to centrifugal pulverizing one step completion; Said pulverising step is operated as follows: the glass metal after the fusing sprays through porous nozzle under the above high pressure gas effect of 2MPa; Make it to form the melten glass drop that splashes down downwards; The melten glass drop in dropping process with the collision of the drum surface of high speed rotating, feed the recirculated water cooling in the rotary drum, the acting in conjunction that glass metal drops in gravity, cf-, sputter power form down particle diameter between 1～100 micron glass particle and get rid of in the powder collecting bin.
The further technical scheme of the present invention is that said glass drop forms the size of particle diameter through regulating the pressure-controlling of rotary drum rotating speed and sparging gases.
The present invention is directed to glass powder method hollow glass micropearl production technique improves; Adopt a kind of new centrifugal pulverizing replace in the original production process water broken → oven dry → coarse crushing → process in small, broken bits; Simplified production technique, cut down the consumption of energy, minimizing equipment and personnel cost; Operation is easy to control with quality, and the shrend effect is also better; The present invention can reduce production costs 14～20%, improves ultimate compression strength 4.8～15%.
