2C Switching Block 2010 H without Backpropagation

1. Introduction to top
The APSON 2C Switching Block 2010 H without
Backpropagation belongs to the class of the special switching blocks
for 2-components lacquers with hardener. Due to its characteristics it
improves the quality and increases the efficiency of the coating
process.
This type of switching block is particularly suitable to the
employment in automatic coating systems with often to change chemicaly
aggressive media, e.g. lacquers, hardeners, solvents, caustic
solutions, a.o. It is applicable both for 2C normal lacquers and 2C
metalic lacquers.

without Backpropagation
Conventional medium switching blocks for 2-components lacquers
are not optimized and have usually channels for supplying the lacquer
components and at least one channel for exhaust of the lacquer
product. In practice the lacquer product in these channels can harden.
This leads to problems during painting and when rinsing the medium
switching blocks. Clogged medium switching blocks must be exchanged at
expensive timely costs and the medium channels must again be drilled
out.
The APSON 2C Switching Block 2010 H without
Backpropagation is equipped with high-quality dead-space-free APSON
valve technology and has mixing areas with minimum volume within the
ranges within which the master lacquer mixes with the hardener. These
mixing areas are optically examinable and fastly cleanable. Hardenings
of the lacquer product cannot develop during the normal operation. If
this should occur nevertheless, the ready status of the APSON 2C
Switching Blocks is restorable in shortest time.
2. Structure to top
The APSON 2C Switching Block 2010 H without
Backpropagation consists mainly of:
-
A solid valve block with connection- and valve-designations.
-
Five independent APSON valves (see Ordering Data).
-
Tube connectors for the connection of the media.
-
Output cone with output terminal and union nut.
-
Optionally two checkvalves (for pulsation air and solvent).
-
An attaching bracket.

Legenda = SL screw nut/mother, b = SL screw connection
c = Checkvalve, d = Checkvalve
e = Valve, f = Pneumatics connection
g = 2C switching block, h = Union nut
i = Output cone, j = 2C-lacquer outlet
k = Attaching bracket, l = 2 Holes ø7 mm
(horiz. hole spacing 20 mm)
The APSON 2C Switching Block 2010 H without
Backpropagation is is made of inoxidable steel and is fastened by
means of the attaching bracket to a suitable place.
The media hoses are attached by means of the tube connectors at
the associated marked media connections for the master lacquers
(SL1 and SL2), hardener (H), diluant resp. solvent (V/Lo) and
pulsation air (PL). The union nut at the output cone makes possible
fast disassembly for purpose of maintenance resp. inspection.
3. Function to top
The 2C-lacquer product necessary for painting results in the
mixing area of the 2C switching block from simultaneous open valves
for master lacquer and the hardener. The 2C-lacquer product then flows
through the outlet A of the 2C switching block and through a
Mixer/Homogeniser which can be connected at the outlet.

Functional Scheme
LegendChannel lengths: Lv = Lw = Lx = Ly = Lz = 0.2 mm
Channel volume: Vv + Vw + Vx + Vy + Vz = 0.2 ml
For changing the lacquer, the master lacquer in the lacquer hose
can be pushed out through the outlet A by opening the respective
lacquer valve. Subsequently the lacquer hose for the master lacquer is
to be rinsed, as well as the 2C switching block.
For rinsing the 2C switching block, the valves for master
lacquer (SL1 resp. SL2) and hardener (H) are to be closed.
Subsequently, the valves for the solvent (V/Lo) and for the pulsation
air (PL) are to be opened and closed periodically and alternating.
Thus an air/solvent sequence results as follows:
air-solvent-air-solvent...
4. Features to top
APSON 2C Switching Block 2010 H without
Backpropagation has the following capability caracteristics:
-
Produces high-quality medium mixture by turbulent pre-mixing of the media already when meeting the media in the mixing area.
-
Does not form air columns because the mixing area has no media channels.
-
Reaches 100% utilization of material (no hardened medium columns in channels).
-
Is environmentaly careful due to media recuperation and short rinsing times.
-
Is cost-saving due to minimized media consumption.
-
Makes possible simple handling when assembling and maintenance.
-
Has dead-space-free APSON valve technology.
-
Has rinsing- and throughput-optimized media channels.
-
Consists of inoxidable steel, thus corrosion resistant and wear resistant.
-
Is insensitive to caustic solutions and weak acids.
