METHOD FOR MANUFACTURING ISOLATING LAYER ONTO CRUCIBLE AND SPRAYING DEVICE RELATED THERETO

摘要

A method for manufacturing an isolating layer onto a crucible includes the steps as follows: providing a spraying device for the following spraying steps; heating the crucible and measuring the heated crucible to get a first temperature; spraying a slurry on the inner wall of the crucible to form an isolating layer by a spraying unit with a predetermined spraying manner; measuring the isolating layer to get a second temperature; obtaining a value for the difference between the first and second temperatures and judging whether the difference value in a within predetermined difference scope or not, in which the predetermined difference scope is about 6° C.˜12° C.; when the difference value is not in the predetermined difference scope, adjusting the predetermined spraying manner; when the difference value is in the predetermined difference scope, implementing the above spraying steps to the crucible.

1. A method for manufacturing an isolating layer onto a crucible, comprising:
a preparing step: providing a spraying device, wherein the spraying device has a processing unit, a temperature sensing unit electrically connected to the processing unit, and a spraying unit electrically connected to the processing unit; and a plurality of spraying steps, comprising:
A) disposing a crucible at a predetermined position;B) heating the crucible, and then measuring an inner wall of the crucible to get a first temperature by the temperature sensing unit;C) spraying a slurry onto the inner wall of the crucible to form an isolating layer by the spraying unit via a predetermined spraying manner;D) measuring the isolating layer formed on the inner wall of the crucible to get a second temperature by the temperature sensing unit; andE) obtaining a difference value based on the first and second temperatures by the processing unit, and judging whether the difference value is in a predetermined difference scope or not by the processing unit, wherein the predetermined difference scope is about 6° C.˜12° C.; when the difference value is not in the predetermined difference scope, the processing unit transmits a signal to the spraying unit for adjusting the predetermined spraying manner; when the difference value is in the predetermined difference scope, the spraying steps C)˜E) are implemented to the crucible until a plurality of isolating layers stacked on the inner wall of the crucible having a predetermined thickness.
