Abstract

The invention relates to the technical field of casting machining, in particular to a cleaning agent for gradual surface treatment of cast iron. The cleaning agent is prepared from 5 parts of xylene, 15 parts of diethanol amine, 15 parts of dimethylbenzenesulfonic acid sodium salt, 5 parts of citric acid, 1 part of 2-hydroxy-2-tpabta, 15 parts of edetate disodium and 48 parts of water. The cleaning agent for gradual surface treatment of the cast iron is reasonable in formula design and high in oxide layer cleaning efficiency; and particularly, a small amount of 2-hydroxy-2-tpabta is added so that the cleaning processing efficiency of the cleaning agent can be obviously improved, the oxide layer on the surface of a casting can be thoroughly removed, and the surface smoothness can be high.

Description

A kind of for cast iron surface-treated clean-out system gradually

Technical field

The present invention relates to casting processing technical field, specifically relate to a kind of for cast iron surface-treated clean-out system gradually.

Background technology

Foundry goods is various basic parts industrial production obtaining desired product by methods such as forging forming, smelting, punching presses, and iron casting, when machine-shaping, needs to carry out surface treatment to it, to realize the smooth finish on iron casting surface.

Summary of the invention

For the technical problem existed in prior art, the object of the present invention is to provide a kind of for cast iron surface-treated clean-out system gradually, for achieving the above object, present invention employs following technical scheme:

A kind of for cast iron surface-treated clean-out system gradually, be made up of 5 parts of dimethylbenzene, 15 parts of diethanolamine, 15 parts of acid dimethyl sodium, 5 parts of citric acids, 1 part of 2-hydroxyl-2-phenyl acetophenone, 15 parts of sodium ethylene diamine tetracetates and 48 parts of water.

Beneficial effect of the present invention shows:

1) clean-out system, used in surface treatment method, its formulating of recipe is reasonable, remove zone of oxidation efficiency high, particularly with the addition of a small amount of 2-hydroxyl-2-phenyl acetophenone, the clean efficiency of clean-out system can be significantly improved, the zone of oxidation of cast(ing) surface is thoroughly removed, and surface smoothness is high.

2), the preparation method of clean-out system, by the method for progressively adding, the solubility property between each material can not only be improved, the possibility of particle agglomeration can also be avoided, and make the removing oxide layer of clean-out system know that function is promoted significantly.

3), surface treatment method, operating procedure is succinct, focus on clean-out system soaking step, by the formula of appropriate design clean-out system and the preparation method of clean-out system, thus realize the zone of oxidation of cast(ing) surface to remove quickly and efficiently, then improve the recycling degree of foundry goods, improve cast iron light face smooth finish gradually.

Embodiment

Below with reference to embodiment, the present invention is described in detail.But; embodiment content is only citing made for the present invention and explanation; affiliated those skilled in the art make various amendment to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the design of invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.

One, the composition of clean-out system

5 parts of dimethylbenzene, 15 parts of diethanolamine, 15 parts of acid dimethyl sodium, 5 parts of citric acids, 1 part of 2-hydroxyl-2-phenyl acetophenone, 15 parts of sodium ethylene diamine tetracetates and 48 parts of water.

Two, the preparation method of clean-out system is:

First in container, add 5 parts of dimethylbenzene, 15 parts of diethanolamine and 15 parts of water, stir 5 minutes; Then slowly add 5 parts of citric acids, limit edged stirs, and stirs 10 minutes after interpolation; Then slowly add 15 parts of acid dimethyl sodium and 15 parts of water, limit edged stirs, and stirs 15 minutes after interpolation; Then slowly add 1 part of 2-hydroxyl-2-phenyl acetophenone, limit edged stirs, and stirs 5 minutes after interpolation; Finally add 15 parts of sodium ethylene diamine tetracetates and 18 parts of water fast, stir 10 minutes.

Three, for cast iron surface-treated clean-out system gradually

Step 1., use that absorbent cotton is sticky to be got ethyl acetate-ethanol mixing solutions and clean cast(ing) surface, then with dry cloth, foundry goods to be dried, coolly puts 1 day;

Step 2., foundry goods put into the clean-out system being heated to 55 DEG C in advance and soaks 30 minutes;

Step 3., pull rear water out and rinse until the pH value of wash-down water returns to neutrality, dry at 200 DEG C;

Step 4., polishing cast(ing) surface, then carry out anodizing to it, processing parameter is: temperature is 40 DEG C, voltage is risen to 15V in 15 minutes and keeps 10 minutes, then in 5 minutes, voltage is risen to 50V and keeps 6 minutes;

Step 5., pull rear water out and rinse until the pH value of wash-down water returns to neutrality, then dry.

Claims

1., for a cast iron surface-treated clean-out system gradually, it is characterized in that being made up of 5 parts of dimethylbenzene, 15 parts of diethanolamine, 15 parts of acid dimethyl sodium, 5 parts of citric acids, 1 part of 2-hydroxyl-2-phenyl acetophenone, 15 parts of sodium ethylene diamine tetracetates and 48 parts of water.
