Product Description

What is a sandblaster?

 

A sandblaster is a machine that uses abrasive materials. (A metallic abrasive and a non-metallic abrasive) is a mechanical device that uses compressed air to project abrasive particles onto the surface of a workpiece.

It uses compressed air inside the pipeline to transport powdered particles (diameter The material, with a particle size ranging from 1 to 4 mm, is transported from one location to another. As kinetic energy is converted into potential energy during this process, the high-speed sand particles erode the surface of the object, thereby improving its surface quality.

Sand particles are propelled forward within the pipeline by compressed air, exhibiting two states: suspension and pulsation.

The ideal operating condition requires that sand particles exhibit a uniformly suspended flow within the pipeline. The appropriate sand feed rate, as well as the right air volume and air pressure, are the most critical factors determining the effectiveness of sand particle flow. The air volume should be sufficient to ensure that the air velocity inside the pipeline is at least greater than the settling velocity of the largest sand particles. Moreover, the air pressure must be high enough to overcome the frictional losses and resistance encountered by the air as it propels the sand particles through the pipeline. Only in this way can we guarantee smooth and unobstructed flow of sand particles within the pipeline.

However, as the pipeline length increases, the wind pressure gradually decreases and the air flow velocity slows down. Initially, suspended particles exhibit non-uniform suspension flow, which then evolves into a flow state characterized by uneven density. When the air flow velocity falls below a certain threshold, pulsating flow patterns begin to emerge. As the air flow velocity continues to decrease, some material particles come to rest at the bottom of the pipeline, while others continue to slide forward. This causes the layer of stagnant material to become unstable and eventually leads to blockage, resulting in system failure. This is precisely what we strive to avoid during the sandblasting process.

Due to the impact and cutting action of the abrasive material on the workpiece surface, the sandblasting machine imparts a certain degree of cleanliness and varying degrees of roughness to the surface, thereby improving its mechanical properties. As a result, the workpiece exhibits enhanced fatigue resistance, increased adhesion between the workpiece and any applied coatings, and prolonged durability of the coating film. Additionally, sandblasting facilitates smoother flow and better decorative effects of the coating. It effectively removes surface impurities, discolorations, and oxide layers, while simultaneously roughening the substrate surface, relieving residual stresses in the workpiece, and enhancing the surface hardness of the base material.

 

 

Dry sandblasting machine

Inhalation-type dry sandblasting machine

( 1 ) General composition

A complete dry-blast sandblasting machine typically consists of six components. System Composition namely, the structural system, the medium dynamics system, the piping system, the dust removal system, and the control system, and Auxiliary system

( 2 ) Working principle

Inhalation Dry sandblasting machine It is powered by compressed air and generated within the spray gun through the high-speed movement of the airflow. Negative pressure The abrasive material is drawn into the spray gun through a sand-conveying pipe and ejected through the nozzle, striking the surface to be processed and achieving the desired machining effect. In a suction-type dry sandblasting machine, compressed air serves both as the feed power and as the accelerating force for the jet.

Pressure-fed dry sandblasting machine

For the pressure-fed dry sandblasting machine, we’ll focus on the pressure-fed sandblasting working unit—the basic unit consisting of a pressure tank and a spray gun.

( 1 ) General composition

A complete pressurized dry blasting machine working unit typically consists of four systems, namely: Pressure tank — Medium-powered system, piping system, control system.

( 2 Push-in type Dry sandblasting machine The working principle

The pressure-fed dry abrasive blasting machine uses compressed air as its power source. By building up working pressure within a pressure tank through compressed air, the abrasive material is forced through a sand-discharge valve into a sand-conveying pipe and then ejected through a nozzle, striking the surface to be processed and achieving the desired machining effect. In a pressure-fed dry abrasive blasting machine, compressed air serves both as the feed power and as the accelerating force for the jet stream.

Liquid sandblaster

Liquid sandblaster Compared to Dry sandblasting machine In particular, the most significant feature is the effective control of dust pollution during the sandblasting process, thereby improving the working environment for sandblasting operations. Liquid sandblasting (also known as wet sandblasting) is a new sandblasting technology that has evolved from the traditional dry sandblasting method, which has been in use for nearly a century. Transforming dry sandblasting into liquid sandblasting represents a major breakthrough in sandblasting techniques. [2]

General composition

A complete liquid abrasive blasting machine typically consists of five systems: the structural system, the media power system, the piping system, the control system, and the auxiliary system.

Working principle

A liquid abrasive blasting machine uses the abrasive slurry as the feed power source. A slurry pump delivers the uniformly mixed abrasive slurry (a mixture of abrasive particles and water) into the spray gun. Compressed air serves as the accelerating power source, entering the spray gun through an air supply pipe. Inside the spray gun, the compressed air accelerates the abrasive slurry that has been fed in, and then propels it out through the nozzle, spraying it onto the surface to be processed to achieve the desired machining effect. In a liquid abrasive blasting machine, the slurry pump provides the feed power, while compressed air supplies the acceleration power.

Rubber and plastic When an alloy material becomes brittle, the burr becomes brittle before the product itself. Within the time gap between the burr’s brittleness and the product’s failure to become brittle, a high-speed jet of polymer particles is used to impact the product’s burr, thereby efficiently removing burrs from rubber-plastic alloy products as well as aluminum and zinc alloy products.

Rubber-plastic alloy materials all belong to polymer materials and will exist in different states at different temperatures. Phase state From the perspective of phase transitions, a material’s change is merely a shift in its mechanical state. When a material is subjected to low-temperature conditions, its state undergoes a transformation; however, once it returns to normal room temperature, all its properties will be restored.

The physical properties of elastomer alloy materials change as the temperature decreases: they harden.   Brittleness → Vitreousness

After the temperature drops, the elastomer alloy material begins to harden and will not deform or get damaged below its embrittlement temperature. Once it returns to room temperature, its physicochemical properties remain unchanged.
