about the use of EVERLAST®C.A.R.O.L as a basecoat primer and topcoat - all in one - for mobile vacuum systems for wet and dry waste.

Dipl. Engineer Rainer Holzhey is a specialist in the field of corrosion protection and mechanical engineering.He is consultant for industrial enterprises, to upgrade to latest technology, value preserving of infrastructures and choice of contruction materials.
EVERLAST®C.A.R.O.L stands out with positive results as the superior rust-protection for steel structures that are exposed to high abrasíve wear and tear, as well as humid, chemical-loaded air-flow. Following here is the actual report of a sucessful rust-prevention under extreme conditions:
|
|
Starting Point
|
The company is based in Erfurt.In the preceding six years until 1999, numerous other epoxy-/or urethane-based coatings have been applied to rust-proof their mobile environment protecting installations. All these primers failed after only a few weeks in use. They were not suited for the extreme operating conditions. ================================================== |
|
| Vacuum sucking equipment |
The. Heimbürger Corporation owns two mobile vacuum sucking units of typ DISAB (of different construction) with an air flow capacity of up to 12.000 m3/h.
==================================================
|
|
| Stress factors |
The high air velocity of 40m/sek evidently exposes the tubing systems and the receiver steel tank to wear and corrosion. Specificly the intake-ducts are prone to severe abrasion.Her the highest air-pressure drop exists and most extreme corrosion can occur.
The sucked-in humid air is contaminated with suspended sticky and abrasive matter and may contain toxic and chemically active substance in the form of solids, liquid droplets or gas. ==================================================
|
|
| Corrosion+Abrasion |
Due to high mechanical and chemical stress a long-lasting anti-rust coating is of great importance. The primers applied during the first six years did not give the expected results.Coatings already showed damage after 3rd operational use and were totally non-operational after the 6 time. Priming therefore had to be started all over again quarterly, in order to minimize the breakdowns of costly equipment through wear and tear.
==================================================
|
|
| Sucessful results using EVERLAST®CAROL |
Since first applied 2 years ago the use of EVERLAST®C.A.R.O.L has shown the desired results. Until now - even under most severe operation conditions - no corrosion has set in.
Equipment treatet has been for the vacuuming of gravel beds on rail-track systems as well as for the removal of liquid manure on live stock farms. ==================================================
|
|
| Priming with EVERLAST®C.A.R.O,L |
Heimbürger Corporation used two separate treatment methods for the EVERLAST®C.A.R.O.L-coating of their mobile vacuum sucking equipment:
It is significant to notice that none of the sucked-off sediments adhere to the walls and the emptying of the box-tank can now be done without difficulty. ==================================================
|
|
| Customers served |
During the last two years both types of vacuum sucking units protected with EVERLAST®C.A.R.O.L were used to handle environmentally hazardous wastes from : Figure7
==================================================
|
|
| Efficiency values | EVERLAST®C.A.R.O.L - makes it possible to create an wear and chemical resitant anti-rust protection-layer on easy-weldable ordinary carbon steel. Thus giving the creative-working engineer additional freedom of design and "great stainless-steel looks" for his equipment and infrastructures for many years of service.
A great investment. ================================================== |
