Abstract
The invention discloses a method for improving the service life of hardware in a highly corrosive environment. According to the method, before the hardware is used, the surface of the hardware is roughened, e.g. the surface of the hardware is processed into a frosted surface, and the hardware is soaked in a lime water environment for about one week before being used; firstly micro-corrosion treatment is carried out to the hardware and then glass glue is applied on the surface of the hardware which is contacted with the air; the glass glue is air dried, becomes hard and cracks after staying in the highly corrosive air for a long time; because the hardware is soaked in the lime water beforehand, calcium hydroxide is attached on the surface of the hardware; when the glass glue cracks, the calcium hydroxide which is exposed in the cracks react with the strong acid gas, calcium sulfate is generated and deposited into the cracks, so that the corrosive air is better prevented from being contacted with the hardware, the hardware is effectively prevented from being corroded and aged, the hardware is effectively protected, the service life of the hardware is improved, and the method is convenient to operate.
Description
?
Technical field
The invention belongs to gold utensil resist technology field, gold utensil method of life in particularly a kind of raising strong corrosive environment.
Background technology
Gold utensil in the scope of highly acid chemical plant receives the erosion of strong corrosive environment easily, and severe corrosive is attached on the gold utensil through air, and soon with its corrosion, thereby reduced service life; And gold utensil is as fixing firm parts, in case be corroded, its effect is easy to be affected; Cause the equipment of connection loosening, perforation enlarges, if things go on like this; Gold utensil is aging, is easy to cause gold utensil that accident loosening even that come off takes place, and its consequence is very serious.
Summary of the invention
The present invention provide a kind of effectively prevent gold utensil corrosion and aging, effectively protect gold utensil, improve gold utensil method of life in gold utensil service life and the easy to operate raising strong corrosive environment.
Realize that the technical scheme that the object of the invention adopted is: gold utensil method of life in a kind of raising strong corrosive environment, said method comprises the steps:
A, gold utensil is carried out surface roughening handle;
Before b, the use, in the limewash environment, soak gold utensil one all left and right sides time;
C, smear glass cement on the gold utensil surface.
Because the present invention through before gold utensil uses, carries out surface roughening to gold utensil and handles, such as gold utensil is processed matte surface; In the limewash environment, soak gold utensil about one week again before the use, early stage gold utensil is carried out microcorrosion and handle, on the contact-making surface of gold utensil and air, smear glass cement afterwards; Glass cement can be air-dry hard under the long-time situation in the severe corrosive air, but also can crack; Because gold utensil has carried out the limewash immersion in advance; So the gold utensil surface attachment calcium hydroxide, after crackle appearred in glass cement, the calcium hydroxide that crackle partly exposes and highly acid gas reaction generated calcium sulfate and are stacked in the slit; Hinder contacting of corrosive atmosphere and gold utensil better, thus effectively prevent the gold utensil corrosion and aging, effectively protect gold utensil, improve gold utensil service life and this method easy to operate.
The specific embodiment
Gold utensil method of life in the raising strong corrosive environment of the present invention, on a large amount of tests and production practices basis, constantly summing up experience, science is implemented, scientific design, the strict analysis, thereby this method of drawing.
Through embodiment, further specify the present invention below:
Gold utensil method of life in a kind of raising strong corrosive environment, concrete operations are: before gold utensil uses, gold utensil is carried out surface roughening handle; Such as gold utensil is processed matte surface, in the limewash environment, soak gold utensil about one week again before the use, early stage gold utensil is carried out microcorrosion and handle; On the contact-making surface of gold utensil and air, smear glass cement afterwards; Glass cement can be air-dry hard under the long-time situation in the severe corrosive air, but also can crack; Because gold utensil has carried out the limewash immersion in advance; So the gold utensil surface attachment calcium hydroxide, after crackle appearred in glass cement, the calcium hydroxide that crackle partly exposes and highly acid gas reaction generated calcium sulfate and are stacked in the slit; Hinder contacting of corrosive atmosphere and gold utensil better, thus effectively prevent the gold utensil corrosion and aging, effectively protect gold utensil, improve gold utensil service life and this method easy to operate.
Claims (1)
1. one kind is improved gold utensil method of life in the strong corrosive environment, and it is characterized in that: said method comprises the steps:
A, gold utensil is carried out surface roughening handle;
Before b, the use, in the limewash environment, soak gold utensil one all left and right sides time;
C, smear glass cement on the gold utensil surface.
