For blasting work need the following equipment: compressor, sand blasting machine, the nozzle tip guard, abrasive blasting sleeve protective form of the operator-Sandblasting filter for breathing.
The weakest link in the system determines blasting cleaning efficiency. If at least one of the elements is not working properly, it suffers from all the work and you lose time, money and customer trust. To avoid this, ask yourself these questions:
Compressor: Do enough power supply and compressed air pressure compressor for my work?
Dimensions hoses: Is it enough to have a large diameter air hoses? Large diameter reduces pressure loss, as the compressed air reduces the friction of the wall of the hose.
Connections: At connections and hose of the same diameter?
Power sandblaster: Will the sandblasting machine or clear the scale of its power will last only a thin layer of old paint?
Mobility sandblaster: Will I be able to move on their own sandblaster if I run away?
Nozzle: Which nozzle buy: expensive and durable boron carbide or cheap steel, which fail after 8 hours of operation?
Remote control: Pay for the remote control, or save time and performance, by diverting a partner from its obligations to disable or enable sandblaster?
Dehumidifier: Buy a dehumidifier or spend money on repair sandblasting because crude compressed air and scored agglomerated abrasive compounds and hoses?
Grit for sandblasting works: What is an abrasive and at what fraction of grain to choose? Do not spoil my abrasive thin sheet of aluminum before I cleanse it from rust?
Protective helmet and suit: It will help if my protective suit does not hurt the skin and avoid trips to the hospital and silicosis - an occupational disease
Nylon tip guard are made by precision casting, they weigh little, which helps reduce operator fatigue. Progressive fine thread 50 diameter of the nozzle prevents jamming of the threaded portion with the aluminum. Nylon tip guard has internal helical grooves to secure the sandblasting hose. Supplied with nylon tip guard included sandblasting hose attachment screws.
Aluminum tip guard with union nut made of caprolon for sandblasting hose diameter 32h48 mm. Used for mounting sandblasting nozzle with a cylindrical tip on the sandblasting hose. Aluminum tip guards are made by casting, followed by turning. Tip guard have internal helical groove and securely attached blasting hose. The tip guard of aluminum is very resistant and used in very harsh environments, including the range of temperatures from -50 to +50 degrees. The set includes mounting screws sandblasting hose.
In the treatment of metal surfaces Sand jet, this process has a dual function: it cleans the surface and roughening the surface. This dual effect is achieved by abrasive particles at a high speed bite into the metal surface. Depending on the type of abrasive surface gets off, it is roughened or a primer specific texture. Thus, the purified and roughened metal surface is a perfect base for engaging with modern protective coatings.
Thinking economic categories entrepreneurs know that the corrosion protection is less expensive than replacing the damaged rust design elements. For this reason, now all seek to ensure that, instead of the cheap once the use of paints coatings, which, although more expensive, but much more durable. The difference in price for the purchase and processing more than offset by a greater durability and no need repainting at short intervals.
However, the maximum coating durability can be achieved only if the surface was pre-treated using sandblasting process correctly. If the surface is not completely removed all layers (mill scale or deep layers, as well as the remnants of paint, etc.), it is useless to use better coverage because corrosion process will continue under the paint layer.
On the other hand, preliminary surface treatment using sandblasting process in case of its proper is an economical method by which to achieve the necessary basis for a primer coating.
Currently, each paint factory develops its products to certain rules of the pre-treatment of surfaces prior to application of coatings. For this, before you make any proposal itself the object of cleaning, we strongly recommend that you contact the manufacturers of protective coatings advice on what kind of pre-blasting, they are advised to use, with a view to the subsequent coating.
