1. Introduction to top
The APSON 2C Switching Block XMY-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.
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 XMY-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.
APSON 2C Switching Block XMY-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.
3. Structure to top
The APSON 2C Switching Block XMY-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.
Legend: a = 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 XMY-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.
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.
Channel 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...
