Formula of cleaning agent of wax mould

Abstract

The invention relates to dried model cleaning agent, especially for its formula in casting technique. Its technical proposal is as follows: its component amounts by weight are as follows: pure water 800-1000, sodium nitrite 8-10, and polyethenoxy ether 1. Its advantages are that it can clean organic matter surface; and it is nontoxic, stable, and has good coating effect.

Description

1. Technical field:

[0001] The invention relates to a wax pattern cleaning agent, in particular to a formula of the wax pattern cleaning agent used in casting technology. 2. Background technology:

[0002] At present, the wax patterns used in precision casting (demoulding casting) must be cleaned before they can be well stained with the slurry due to a layer of oily release agent attached to the surface; however, the existing wax pattern cleaning agents generally use ketones Solvents such as aromatic hydrocarbons and aromatic hydrocarbons have strong volatility, which are very harmful to the body, pollute the environment, and damage the health of employees. 3. Contents of the invention:

[0003] The purpose of the present invention is exactly to aim at the above-mentioned defects existing in the prior art, to provide a kind of formula that has non-corrosion, good cleaning effect, nontoxic, stable wax mold cleaning agent.

[0004] The technical proposal is: it consists of ...

Examples

Embodiment 1

[0009] Embodiment 1: 800 kilograms of distilled water, 8 kilograms of sodium nitrite, 1 kilogram of polyoxyethylene ether.

Embodiment 2

[0010] Embodiment 2: 1000 kilograms of distilled water, 10 kilograms of sodium nitrite, 1 kilogram of polyoxyethylene ether.

Embodiment 3

[0011] Embodiment 3: 900 kilograms of distilled water, 9 kilograms of sodium nitrite, 1 kilogram of polyoxyethylene ether.

[0012] The production method is as follows: first prepare 1% sodium nitrite solution at room temperature, which must be pure water or distilled water, take polyoxyethylene ether and sodium nitrite in a weight ratio of 1:9, and slowly inject polyoxyethylene ether into the sub Sodium nitrate solution, after mixing, slowly stir for 15 minutes in an environment of 42-45°, and statically mature in an environment of 42-45° for 2 hours.
