Abstract
The invention provides a method for brushing white alundum powder paint, and the method comprises the following steps of: 1, preparing the white alundum powder paint with a baume degree of 76-84 [Be], carrying out primary brushing of the white alundum powder paint on a surface layer of a sand cavity, lighting the white alundum powder paint immediately after brushing is completed, and then cooling to a room temperature; 2, preparing the white alundum powder paint with the baume degree of 52-58 [Be], carrying out secondary brushing of the white alundum powder paint on the surface layer of the sand cavity, lighting the white alundum powder paint 30-60 seconds after the brushing, and then cooling to the room temperature; and 3, preparing the white alundum powder paint with the baume degree of 42-50 [Be], carrying out tertiary brushing of the white alundum powder paint on the surface layer of the sand cavity, lighting the white alundum powder paint 30-60 seconds after the brushing, and then cooling to the room temperature so as to complete the brushing, thereby ensuring that a brushed coating layer cannot generate air bubbles after being lighted and preventing a casting from being subjected to sand fusion.
Description
Technical field
The present invention relates to the brushing method of coating, be specifically related to be applicable to the brushing method of the white alundum powder coating on sand mold die cavity top layer.
Background technology
In the prior art usually at sand mold die cavity top layer brushing zircon flour coating, so that the sand mold die cavity can play resistant to elevated temperatures effect when cast, avoided foundry goods sand washing when cast to cause the foundry goods burning into sand and sand holes occur, yet the development along with nuclear industry, the price of zirconium material is more and more expensive, zircon flour coating also appreciates thereupon fast, so that production cost improves in a large number.White alundum powder coating take alundum (Al2O3) as main body, its material cost is then much lower than the zircon flour coating take zirconia as main body, the serviceability of white alundum powder coating and brushing performance and zircon flour coating have similarity, but difference is arranged also, the brushing concentration of each level does not prepare in its brushing process, can produce steam bubble after brushing is lighted, foundry goods can produce serious scab.
Summary of the invention
Technical problem to be solved by this invention is to provide the brushing method of white alundum powder coating, can guarantee to brush can not produce bubble after coating is later lighted, and avoids foundry goods to produce scab.
For solving above-mentioned existing technical problem, the present invention adopts following scheme: the brushing method of white alundum powder coating comprises the steps:
Step 1: the preparation Baume degrees is the white alundum powder coating of 76～84 ° of B é, carries out the brushing first time on sand mold die cavity top layer, lights immediately after brushing is finished, and then is cooled to room temperature;
Step 2: the preparation Baume degrees is the white alundum powder coating of 52～58 ° of B é, carries out the brushing second time on sand mold die cavity top layer, treats to light in 30～60 seconds after brushing is finished, and then is cooled to room temperature;
Step 3: the preparation Baume degrees is the white alundum powder coating of 42～50 ° of B é, brushes for the third time on sand mold die cavity top layer, treats to light in 30～60 seconds after brushing is finished, and then is cooled to room temperature, and brushing is finished.
Beneficial effect:
The present invention adopts technique scheme that the brushing method of white alundum powder coating is provided, and has guaranteed can not produce bubble after brushing coating is later lighted, and has avoided foundry goods to produce scab.
The specific embodiment
Embodiment one:
The brushing method of white alundum powder coating comprises the steps:
Step 1: the preparation Baume degrees is the white alundum powder coating of 76 ° of B é, carries out the brushing first time on sand mold die cavity top layer, lights immediately after brushing is finished, and then is cooled to room temperature;
Step 2: the preparation Baume degrees is the white alundum powder coating of 58 ° of B é, carries out the brushing second time on sand mold die cavity top layer, treats to light in 30 seconds after brushing is finished, and then is cooled to room temperature;
Step 3: the preparation Baume degrees is the white alundum powder coating of 42 ° of B é, brushes for the third time on sand mold die cavity top layer, treats to light in 60 seconds after brushing is finished, and then is cooled to room temperature, and brushing is finished.
Baume degrees ° B é is a kind of method of expression solution concentration, and the Baume hydrometer immersion is surveyed in the solution, and the number of degrees that obtain just are Baume degrees.
Embodiment two:
The brushing method of white alundum powder coating comprises the steps:
Step 1: the preparation Baume degrees is the white alundum powder coating of 80 ° of B é, carries out the brushing first time on sand mold die cavity top layer, lights immediately after brushing is finished, and then is cooled to room temperature;
Step 2: the preparation Baume degrees is the white alundum powder coating of 56 ° of B é, carries out the brushing second time on sand mold die cavity top layer, treats to light in 40 seconds after brushing is finished, and then is cooled to room temperature;
Step 3: the preparation Baume degrees is the white alundum powder coating of 42～50 ° of B é, brushes for the third time on sand mold die cavity top layer, treats to light in 45 seconds after brushing is finished, and then is cooled to room temperature, and brushing is finished.
Embodiment three:
The brushing method of white alundum powder coating comprises the steps:
Step 1: the preparation Baume degrees is the white alundum powder coating of 84 ° of B é, carries out the brushing first time on sand mold die cavity top layer, lights immediately after brushing is finished, and then is cooled to room temperature;
Step 2: the preparation Baume degrees is the white alundum powder coating of 58 ° of B é, carries out the brushing second time on sand mold die cavity top layer, treats to light in 60 seconds after brushing is finished, and then is cooled to room temperature;
Step 3: the preparation Baume degrees is the white alundum powder coating of 50 ° of B é, brushes for the third time on sand mold die cavity top layer, treats to light in 55 seconds after brushing is finished, and then is cooled to room temperature, and brushing is finished.
Adopt the brushing method of white alundum powder coating provided by the present invention, guaranteed can not produce bubble after brushing coating is later lighted, avoided foundry goods to produce scab.Adopt the white alundum powder coating take alundum (Al2O3) as main body to brush among the present invention, greatly reduced production cost.
