Abstract
A paint spraying and drying method comprises the following steps: 1. removing oil, removing oil stains on the surface of the ferrous metal workpiece in the production process, and leaching by using a tank; 2. cleaning; 3. derusting, namely removing rust scales on the surface of steel by acid derusting and using a tank leaching method; 4. cleaning; 5. surface conditioning, surface treatment before phosphating, by a tank leaching method; 6. phosphating, namely phosphating the surface of the steel by using zinc phosphating solution and using a tank leaching method; 7. cleaning; 8. drying; 9. and (4) spraying. According to the paint spraying and drying method, each link is carried out through a tank leaching method, and all components in the formula are matched in proportion, so that the spraying effect is better, the paint is not easy to fall off, a special drying process is adopted, the special attachment time is prolonged, and the use cost of mechanical equipment is reduced.
Description
Technical field
The present invention relates to spraying technology field more particularly to a kind of paint spraying and the methods of drying.
Background technology
Most of mechanical equipment is required for carrying out surface anti-skidding and anticorrosion by spray painting, to extend the longevity of whole equipment
Life, and traditional lacquer spraying technique knowledge will especially direct spraying and equipment surface, the problems such as causing to be easy to fall off, to make equipment
It is more prone to be corroded, shortens service life, increases use cost.
Invention content
In order to overcome the above problem existing for conventional spray paint technique, the present invention provides not easily to fall off after a kind of spraying
Paint spraying and the method for drying.
Present invention technical solution used for the above purpose is：A kind of paint spraying and the method for drying, including
Following steps：
（1）, oil removing, the greasy dirt on removal ferrous metal workpiece surface in process of production, with drill traverse method；
（2）, cleaning；
（3）, derusting, using acidic derusting, the rust deposite of steel surface is removed, with drill traverse method；
（4）, cleaning；
（5）, table tune, for the surface treatment before phosphatization, with drill traverse method；
（6）, phosphatization, make steel surface phosphatization with Zinc phosphating solution, with drill traverse method；
（7）, cleaning；
（8）, it is dry；
（9）, spraying.
The step（1）Middle caustic dip formula：Sodium hydroxide 5%, sodium phosphate 5%, tertiary sodium phosphate 5%, OP-10 emulsions 0.2%,
93 ~ 98 DEG C of temperature, 8 ~ 10 minutes processing times.
The step（3）Middle acid pickling and rust removing formula of liquid：Technical hydrochloric acid, the corrosion inhibiter 8% of concentration 42%, temperature：Room temperature.Processing
Time 5-10 minute.
The step（5）In, it is slowly added, stirs to dissolve by every 1.5 ~ 3 kgs/tonne of dosage when matching tank liquor.Table
The operating condition of adjustment is pH value 6.5 ~ 8.5, temperature：Room temperature, half a minute time.
The paint spraying of the present invention and the method for drying, each ingredient is matched during links are carried out and are formulated by drill traverse method
It is not easily to fall off than collocation so that spraying effect is more preferable, and special drying process is used, the attachment time especially is extended,
Reduce the use cost of mechanical equipment.
Specific implementation mode
A kind of paint spraying of the present invention and the method for drying, steps are as follows：
（1）, oil removing, the greasy dirt on removal ferrous metal workpiece surface in process of production, with drill traverse method；Remove ferrous metal workpiece
The greasy dirt on surface in process of production, with drill traverse method.Caustic dip formula：Sodium hydroxide 5%, sodium phosphate 5%, tertiary sodium phosphate 5%,
93 ~ 98 DEG C of OP-10 emulsions 0.2%, temperature, 8 ~ 10 minutes processing times.Inspection method after processing：With brush brush, mesh after washing
Survey whether greasy dirt removes.
（2）, cleaning；
（3）, derusting, using acidic derusting, the rust deposite of steel surface is removed, with drill traverse method；Acid pickling and rust removing formula of liquid：Concentration 42%
Technical hydrochloric acid, corrosion inhibiter 8%, temperature：Room temperature.Processing time 5-10 minute.
（4）, cleaning；
（5）, table tune, for the surface treatment before phosphatization, with drill traverse method；When with tank liquor slowly by every 1.5 ~ 3 kgs/tonne of dosage
Addition, stirs to dissolve.The operating condition that table is adjusted is pH value 6.5 ~ 8.5, temperature：Room temperature, half a minute time.
（6）, phosphatization, make steel surface phosphatization with Zinc phosphating solution, with drill traverse method；
（7）, cleaning；
（8）, it is dry；Dry aggretion type coating, such as amino paint, acrylic acid paint, epoxy resin coating, general baking temperature is 140 ~
50 DEG C,（Acrylic paint needs static put 5 minutes to be toasted again）35 ~ 40 minutes time.
（9）, spraying.
The present invention is described by embodiment, and those skilled in the art know, in the spirit for not departing from the present invention
In the case of range, various changes or equivalence replacement can be carried out to these features and embodiment.In addition, in the religion of the present invention
