Sandblasting and three-dimensional engraving operations, sandblasting for shipbuilding, professional high-efficiency processing machines for surface treatment, derusting, anticorrosive treatment and fancy sandblasting of denim clothing before painting steel structures such as bridges, railways, containers, and petrochemical facilities.
The automatic pressure-relieving steel structure derusting and anti-corrosion sandblasting machine produced by Dongguan Meijun sandblasting equipment is an automatic sandblasting machine with automatic safety protection performance operated by one person. It is easy to use, the wearing parts are separated from the column parts, and the replacement consumables are reduced. Cost. At the same time, our tanks are welded by large machines to ensure product quality. Our tanks have been finely sanded, sandblasted and sprayed, and have strong rust resistance.
FRP industry application introduction:
FRP, resin products, sandblasting machine, mold removal, wax removal, passivation effect is better than manual grinding, saving labor 20 times, and increasing efficiency 40 times!
Sandblasting of glass fiber reinforced plastic products and resin products using a sandblasting machine can quickly clean up the wax attached to the surface after demolding, passivate the surface of the product, increase roughness, and make subsequent spray painting, increase the adhesion of batch powder, and life Improve 3-5 times.
After experiments, you can save 20 times labor and increase efficiency 40 times.Case: A face-size glass fiber reinforced plastic mask model, manual polishing with a hand mill takes 5-8 minutes, while using a sandblaster takes about 10 seconds, If the one-person pressure sandblasting machine produced by Meijun sandblasting equipment is used, the efficiency will be higher, which can save a lot of labor and increase the efficiency of product molding.
At the same time, the pressure-relief automatic exhaust sand blasting machine produced by Meijun is safe to use, generates air pressure when it is turned on, and removes the air pressure when it is stopped. All operations are controlled by only one person through the control switch on the hand. Welcome to understand!
Sand cylinder diameter: 600MM Sand cylinder height: 1300MM
Sand tank volume: 0.3 cubic
Descaling efficiency: 15-30 square / hour
Air consumption: 3 m3 / min (single shot)
Air source pressure: 0.6-0.7MPA
Divided by configuration:
1) Basic type: pure manual type, which is basically a pressure-proof assembly.
Intake valve (ball valve control switch) + sand control valve (ball valve control switch). Without electric control and pneumatic control system, 2 people need to operate at the same time, one person takes a gun to blast the workpiece, and the other controls the machine switch.
2) Holding pressure type: electric control type or pneumatic control type
Intake valve (aluminum alloy globe valve) + sand control valve (EMPAIR air control sand valve or manual sand valve).
The sand tank always maintains pressure and needs to be manually depressurized.
Features: Regardless of whether the switch is turned on or off once, as long as the exhaust ball valve on the top and side of the sand tank is not opened, the pressure in the cylinder will not be removed (except for manual sand valve self-draining: it will cause serious sand pipe accumulation), suitable Short-time point blasting.
3) Pressure relief type: electric control type or pneumatic control type
Intake valve (aluminum alloy globe valve) + sand control valve (EMPAIR air control sand valve or manual sand valve) + automatic air control exhaust valve.
When sand blasting works, the pressure in the tank is the working pressure. When the tank is stopped, it is automatically vented. The pressure in the tank is 0, which is suitable for long-term large-area blasting.
The pressure in the tank will never exceed the limit pressure, which plays a role in ensuring safety and is also a necessary assembly method for automatic sand return.
1.Compact structure, superior performance, simple and convenient operation.
2.The design and production of the cylinder body comply with the pressure vessel standard, which is safe and reliable.
3.Using standard universal parts, easy to replace and lower cost.
4.Instantaneous control function is installed, which adopts electric control or pneumatic control to meet different needs of customers and can be operated by one person alone.
5, the shell is sandblasted and uses advanced anti-rust spray paint to prevent rust.
6, add wheels, easy to move.
Advantages of using pressure blasting machine:
It can replace the pickling and phosphating process without involving the problem of sewage discharge. Quick blasting and rust removal, while changing the surface roughness, it can also remove welding slag, burrs and flashes.
High efficiency, low cost and good quality are unmatched by traditional chemical and manual rust removal. After blasting, the quality of the paint is good, and the coating has a long life. It is a universal process currently used internationally.
Working principle of pressure blasting machine:
This machine uses a pressure-feeding type sand blasting (shot blasting) mechanism, which uses compressed air to flow at high speed in a high-pressure tank to form a high-pressure effect, and the sand in the high-pressure tank is ejected through a sand conveying pipe.
Then the compressed air is sprayed from the spray gun nozzle to the workpiece surface at high speed to achieve the purpose of sandblasting.
Application range of pressure mobile sand blasting machine:
Mainly used for: surface cleaning, engraving, spray processing, descaling, burrs, welding scars, spraying glass shots, strengthening the surface of decorative parts. Can also be used for spraying,
Pre-plating process (all surface treatments to improve the adhesion of the coating surface)
Pressure mobile sand blasting machine products are widely used in
1) Sandblasting of glass, marble, ceramic tiles, molds, fitness amusement equipment and other surfaces and three-dimensional carving and carving operations;
2) Surface blasting of steel structures for shipbuilding, bridges, railways, containers, petroleum pipelines, chemicals, mining facilities, water conservancy projects, port construction, etc.
3) FRP, carbon fiber, plastic products
Sand used for blasting and rust removal requires particles that are hard, angular, dry and free of dirt and other impurities;
Brown corundum, black corundum, and corundum are better for high requirements. Quartz sand is better for economical requirements. Coarse river sand is also available.
The selection of abrasives should take into account factors such as sand transport conditions, unit price, and recycling capacity;
The particle size of the sand is preferably 0.5 ～ 1.5mm. It must be dried before screening and stored in the shed or indoor.
The size of the sieve is: 40 to 48 holes for coarse sieve (particle diameter 1.2mm), 372 to 476 holes for fine sieve (particle diameter 0.3mm)
Air source control:
The compressed air must be processed by a cooling device and an oil-water separator to ensure that it is dry and free of oil;
The oil-water separator must be cleaned regularly;
The air pressure of the air compressor is 6.0 × 105 ～ 6.5 × 105Pa.
0.5 × 105 to 1.0 × 105Pa. Generally, the pressure of the sand bucket is 4.5 × 105 ～ 5.5 × 105Pa, and it must not be less than 4.0 × 105Pa.
Job protection requirements:
Before sand blasting, the non-blast blasting parts should be protected.
Before blasting, check whether the various pipes and control valves of the blasting machine are connected, whether they are in the appropriate switch position,
Is the protective tool, safety belt (rope) and oxygen supply device worn by the blaster safe and reliable, and the wear of the nozzle, when the orifice
The nozzle should be replaced when the diameter is increased by 25%.
The distance from the nozzle to the surface of the base steel during sand blasting is preferably 100 to 300 mm.
The angle between the spray direction and the surface normal of the base steel is preferably 15 ° ～ 30 °. After sandblasting and rust removal, before the next process,
In case of rain or other conditions that cause the surface of the base steel to be wet, after the environment reaches the construction conditions, use a dry
Compressed air is used to dry the surface after construction. If sand blasting is required, the abrasive requirements must not be reduced to avoid reducing the roughness.
