Summary of the invention
The purpose of the present invention is to propose to a kind of plastic housing paint removing process, solve the undesirable modeling of spray paint in the prior art Material shell how depainting recycle the problem of.
To achieve the above objectives, the technical solution adopted by the present invention are as follows:
A kind of plastic housing paint removing process, comprising the following steps:
Step 1: being added paint stripper in container, and the plastic housing for needing depainting is put into container and is impregnated 3-8 hours;
Step 2: plastic housing is pulled out from container;
Step 3: the plastic housing pulled out is put into Rinsing Area and is impregnated 1-3 hours;
Step 4: remnants paint slag is shaved using tool;Use brush cleaning plastic housing;
Step 5: plastic housing is placed in Dropbox one by one;
Step 6: Dropbox being put into oven and is toasted 20-40 minutes, removes moisture removal, and depainting is completed.
Preferably, the plastic housing paint removing process further includes step 7: plastic housing goes up spraying coating line again.
Preferably, the plastic housing for needing depainting is put into container and impregnates 5-6 hours by the step 1.
Preferably, the step 6, it is 25-35 minutes that Dropbox is put into the time toasted in oven.
Preferably, the step 1, the paint stripper being added in container include each group grouping of following weight percent At: the benzyl alcohol of 35%-55%, the butyl acetate of 25%-45%, the ethyl alcohol of 8%-15%, the ethanol amine of 5%-10%, 2%- 5% hydrogen peroxide.
Preferably, the step 1, the paint stripper being added in container include each group grouping of following weight percent At: the benzyl alcohol of 40%-50%, the butyl acetate of 30%-40%, the ethyl alcohol of 8%-10%, the ethanol amine of 5%-8%, 2%- 5% hydrogen peroxide.
Preferably, the step 1, the paint stripper being added in container include each group grouping of following weight percent At: 35% benzyl alcohol, 45% butyl acetate, 8% ethyl alcohol, 10% ethanol amine, 2% hydrogen peroxide.
The invention has the benefit that plastic product can completely be removed paint by plastic housing paint removing process of the invention, together When can reduce damage to plastic housing to the greatest extent, and product can be allowed to carry out returning spray, greatly to reduce the report of plastic housing It is useless, product yield can be effectively promoted, plastic housing paint removing process of the invention is simple and environmentally friendly.
