Automotive Industry: Body touch-up painting, film coating, and detail repair, requiring high-precision atomization.

Industrial Coating: Photocatalyst spraying, anti-corrosion coating, suitable for high-pressure environments and high-viscosity coatings.

Wood and Ceramics: Furniture clear coat spraying, ceramic glaze application, relying on uniform spray width control. 

V. Key Points for Use and Maintenance

1.Operating Specifications

Spray Distance: Maintain a vertical distance of 200 mm and move at a constant speed to avoid sagging or dry spraying.

Parameter Adjustment: Adjust the air pressure (2-4 bar) and paint output according to the viscosity of the coating. Test spray to verify the effect before proceeding with the operation. 

2.Maintenance and Care

Cleaning: Immediately after use, thoroughly clean the paint channel with a solvent, paying special attention to the nozzle and air cap to prevent clogging (especially for two-component paints).

Lubrication: Regularly apply lubricating oil to components such as the needle valve and spring to maintain the flexibility of the sealing gasket.

Storage: For short-term non-use, soak the gun head in solvent, but avoid soaking the entire gun to prevent the sealing gasket from aging.

FAQS:

Question A: How to choose a spray gun that suits you?

Answer A: Here are some methods for choosing a paint gun that suits you: 

Consider the requirements for spraying. 

Spray type: The air spray gun is suitable for most surface treatments such as those on cars, furniture, and metal products, and can provide a fine and uniform coating; the airless spray gun is suitable for large metal structures or floor coatings where quick drying or thick coatings are required, and has high spraying efficiency. 

Spray area: For small-scale spraying, a small spray gun can be selected, such as for model making or local repairs of furniture; for large-scale spraying, a large spray gun is required, like for spraying on building exteriors or large equipment. 

Degree of precision: For delicate tasks such as painting and spraying of handicrafts, a spray gun with a small nozzle is recommended. It allows for precise control of the paint flow and enables detailed spraying. If the task involves quickly covering a large area with ordinary spraying, a larger nozzle is more suitable. 

Pay attention to the characteristics of the spray gun 

Control method: Gravity-fed painting type is suitable for small-batch or precise work, as the paint flows to the nozzle by gravity and is easy to control; Pressure-fed painting type is suitable for large-scale spraying, as the paint is sent to the nozzle through air pressure, and the efficiency is higher. 

Adjustment performance: A good spray gun should be able to adjust the air supply volume and paint output to meet different coating and spraying requirements. It can also adjust the spray pattern, such as a narrow pattern for fine areas and a wide pattern for large-scale spraying. 

Matching spray coating material 

Different spray guns are suitable for different types of coatings, such as water-based paint, oil-based paint or powder coatings, etc. Water-based paint has a higher viscosity and may require a larger nozzle and a specially designed atomizing cap for the spray gun; for spraying powder coatings, a dedicated electrostatic powder spray gun is needed. 

Taking durability and ease of use into consideration 

Material and Workmanship: The gun muzzle and the hood are made of brass, which is of good quality and sturdy. The gun needle should be made of high-quality stainless steel. The gun body is mostly made of aluminum alloy and aluminum. Pay attention to checking the details of the workmanship, such as whether it is tight and if there are any burrs. 

Trigger flexibility: A spray gun with good trigger flexibility requires less effort to operate and is less likely to cause fatigue even after prolonged use. 

Pay attention to the brand and the price 

Choose reputable brands such as BSS, this brand offer more reliable product quality and after-sales service. Set a reasonable budget. Generally, higher-priced spray guns have better performance and durability, but you should choose products with better value for money based on your actual needs.

Question B: How to adjust the air output and paint output of the E70 spray gun?

Answer B: The following are the methods for adjusting the air output and paint output of the E70 spray gun: 

1.Air volume adjustment 

Locate the adjustment knob: Usually, there is a compression air adjustment knob at the tail end of the spray gun. 

Adjustment method: Turn this knob to the maximum position, then adjust the air pressure to approximately 2 - 2.5 bar using the pressure regulating gauge provided with the spray gun as needed. However, in actual use, the air pressure can be appropriately adjusted within the range of 0.4 - 0.6 MPa based on the type of paint, its viscosity, and the specific requirements of the spraying process. 

2.Adjustment of paint output 

Adjust the flow control knob: Usually, there is a paint flow adjustment knob on the spray gun. Tighten it, then rotate it counterclockwise by about 2.5 turns. If you need to increase the paint output, you can continue to rotate the knob counterclockwise; if you want to reduce the paint output, then rotate the knob clockwise. 

Consider other factors: The amount of paint output is also related to the viscosity of the coating. The higher the viscosity, the less the paint output. The viscosity of the coating can be adjusted by changing the ratio of the diluent, thereby affecting the paint output. 

When adjusting the air supply volume and paint output, it is necessary to comprehensively consider the balance between the two, while also observing the atomization degree of the paint liquid at the spray gun nozzle and the size of the fan-shaped area, in order to achieve the best spraying effect.
