Sandblasting Dust Collector

Do I need to use a Sandblasting Dust Collector?

Probably one of the main cons of using the sandblasting technique is the dust created by the very nature of the process. Sandblasting creates dust and generates a lot of dirt you must properly handle to not convert your working area in a garbage zone.

Keep in mind that blast cleaning is by its very nature a dusty process. But the main objective of a dusto collector is not keeping the area clean but to maintain visibility while blasting by exchanging the air in the cabinet. To maintain this level of visibility, a dust collector should provide at least 6 to 8 air changes per minute.

My recommendation of the sandblasting dust collector to be used depends on the work to be done. I’ll explain in detail. It is not the same using sandblasting to get rid of old paint in a car than small pieces of ceramic to be polished.

Basic considerations in choosing the right dust collector must include sandblasting use, generated noise, estimated cost, maintenance process and costs, filtration, and operating area (how large, how clean, how humid and what sort of ventilation is available.)

If you would like to buy a dust collector that actually works there are a few models available.

TPTools makes a couple different models, but you’re going to need to bring your wallet. Their VAC-36 is the one that I recommend since it has a HEPA filter built into it, but it costs about $350.
Cyclone makes one that does not have HEPA and is available from Northern Tools for $199.
A similar Cyclone model is available from ENCO for $153.

Sandblasting At Home Dirty Tricks

Sandblasting Expert — Thu, 08 Jul 2010 07:57:26 +0000

Sandblasting is an industrial technique that propells very fine bits of material at high-velocity to clean or etch a wide range of surfaces. Although is extensively used in industrial areas you can also use sandblasting at home.

Here are my dirty tricks to use sandblasting at home without problems:

1.- First, you must prepare the zone in which you will make the work. If you don’t have a sandblasting cabinet you can easily build a homemade sandblast booth. If you want to make the sandblasting work outdoor first you must consider that the area can not be affected by the wind.

2.- Which sandblasting equipment is more appropiate to sandblast at home?

You can use sandblasting kits that will remove unwanted rust, paint and scale in no time. My main recommendation is that you don’t have bother with the small feed sandblasters like siphon blasters. I have one and it goes for about 10 seconds between fills. If you’re serious about doing big areas, you might consider one of the inexpensive 40lb blasters .

The siphon feed design sprays most abrasives including glass beads, aluminum oxide, steel grit, silicon carbide, walnut shells and more. easily removes rust, scale, and paint from parts and small equipment leaving a satin finish that will allow for further painting preparations or applying the final coat.

On the other hand, 40 Lb. pressurized abrasive blasters are better tools for sandblasting at home purposes. Pressurized design gives 30% more blasting power than siphon blasters.

3.- Always use protective accessories like sandblaster gloves and protective glasses.

Be creative and etch designs or lettering on any number of surfaces including glass tile, wood working and furniture.

Sandblasting Vs Soda Blasting in Yachting

Can I use sandblasting technique to remove the old paint from my boat?

Recently I stumbled upon a forum post in a sailing website. One forum member of this website was worried about which specific technique is more appropriate to get a perfect surface finish in yachts.

According to sailing experts soda blasting is perfect for fiber glass boats but it gets poor results in steel frame yachts. One user even claimed that soda blasting left a pitted surface but did not remove all the loose paint . He had to come back and re-do it. On the other hand, sandblasting technique with “000″ grit sand gave the best result back to steel surfaces in boats.

In yachting both techniques, sandblasting and soda blasting, are mainly used to get rid of old paint.

Sandblasting Process

Are you looking for a good sandblaster in your city? There are many cities in the state where you can find such professional companies, but the options in many larger cities are quite large. Sandblasting and coating service providers are becoming more and more popular across the country. These companies maintain the right norms of the correct procedure. In this process, using state of the art equipment a sand stream is packed together with air or water is sprayed against a surface. This process is done to create a coarse and dominant action for cleaning any roughened surface by forcibly driving abrasive particles such as iron globules, emery, powdered quartz, etc.

There are several usages of sandblasting technique. It can be used to clean several parts of the buildings where there are stone works. On such stone work surfaces, obstinate dirt gets accumulated and such cleaning procedure can ensure proper cleaning of filth. Sandblast process can also be used at the foundries for cleaning the casting iron. Moreover, there are several other usages of it such as preparing enameling and painting surfaces along with developing snowy glass designs. Such snowy glass designs can be created by the help of appropriate stencil over a glass plate with slight sandblasting. The exposed parts of the glass plate will be filled by the rough particles after the process and in that way the snowy look will appear.

Sandblasting is such a process where the person who is conducting the operation must take appropriate measures to remain safe. There are several toxic particles such as zinc or lead, which get discharged during the operation. Such exposure to harmful particles is noticed mainly during the cleaning process of surface coatings of commercial constructions. Hence, proper equipments, gears, appropriate attire and goggles are to be used by the sandblaster during the operation. Harmful particles keep flying dangerously during the process and working without proper eye protection can be really unsafe and harmful for the crew.

The workers who conduct such procedure require constant supply of fresh air during the operation. General air breathing equipment must be used during the process so that the operators of the machine can get the fresh air in the surrounding filled with harmful pollutants. It is also to be ensured that the tools used to supply fresh air like the hoses are in good condition so the operator gets clean and fresh air.

When the process gets completed, the operators must keep wearing the protection gears until they get out completely from the vicinity where the suspended harmful particles flutter in the air.

There are several safety measures that need to be maintained to handle the sandblasting machine. During the operation, all the rough particles are placed in a sandblast pot and this pot must be properly grounded every time after the use. After the procedure of sandblasting gets over, the machine must be checked properly by the expert to ensure that all the nozzles and other equipments are in safe condition.

What Is Wet Sandblasting?

You can think that sandblasting is always dry. The slightest amount of moisture will plug up a blaster. You ever go to the beach and pick up wet sand with your hand?, theres no way that will ever go though a nozzle.

But, in fact, there is a wet sandblasting type. Wet sandblasting is more like powerwashing,where sand is mixed in with the water for abrasive purposes.I’ve seen it used in industrial applications like bridges or on sidewalks.

Wet Sandblasting is a common procedure for removing paint and rust from steel or other metal surfaces. With this procedure we use an abrasive material mixed with the waterjet to create an abrasive spray to create the desired white metal finish, perfect for recoating.

A recent development along the lines of abrasive cleaning is “Water Soluble Media” (baking soda) which offers distinct advantages over wet sand blasting.

For most cleaning and depainting jobs, the new portable soluble media blasting media is largely desirable as disposal costs are usually greatly reduced. Because of the extreme abrasive qualities of different sand and garnet, baking soda based media is often preferred in certain applications such as glass, soft metals, brick and ceramic.
