Important Two-Component Material Information

Important Two-Component Material Information

Isocyanate Conditions

Spraying or dispensing materials containing isocyanates creates potentially harmful mists, vapors, and atomized particulates.

Read material manufacturer???s warnings and material MSDS to know specific hazards and precautions related to isocyanates.

Prevent inhalation of isocyanate mists, vapors, and atomized particulates by providing sufficient ventilation in the work area. If sufficient ventilation is not available, a supplied-air respirator is required for everyone in the work area.

To prevent contact with isocyanates, appropriate personal protective equipment, including chemically impermeable gloves, boots, aprons, and goggles, is also required for everyone in the work area.

Material Self-ignition

Some materials may become self-igniting if applied too thickly. Read material manufacturer???s warnings and material MSDS.

Keep Components A and B

Separate

Cross-contamination can result in cured material in fluid lines which could cause serious injury or damage equipment. To prevent cross-contamination of the equipment???s wetted parts, never interchange component A (resin) and component B (isocyanate) parts.

Moisture Sensitivity of

Isocyanates

Isocyanates (ISO) are catalysts used in two component coatings. ISO will react with moisture (such as humidity) to form small, hard, abrasive crystals, which become suspended in the fluid. Eventually a film will form on the surface and the ISO will begin to gel, increasing in vis- cosity. If used, this partially cured ISO will reduce perfor- mance and the life of all wetted parts.

NOTE: The amount of film formation and rate of crystal- lization varies depending on the blend of ISO, the humidity, and the temperature.

To prevent exposing ISO to moisture:

???Always use a sealed container with a desiccant dryer in the vent, or a nitrogen atmosphere. Never store ISO in an open container.

???Use moisture-proof hoses specifically designed for ISO, such as those supplied with your system.

???Never use reclaimed solvents, which may contain moisture. Always keep solvent containers closed when not in use.

???Never use solvent on one side if it has been con- taminated from the other side.

???Always lubricate threaded parts with ISO pump oil or grease when reassembling.

Changing Materials

???When changing materials, flush the equipment mul- tiple times to ensure it is thoroughly clean.

???Always clean the fluid inlet strainers after flushing.

???Check with your material manufacturer for chemical compatibility.

???Purging Fluid Supply System

Use the criteria listed for each procedure to determine which procedure to use.

FIG. 18. Flow Rate Display

Purging Mixed Material

There are times when you only want to purge the fluid manifold, such as:

???end of potlife

???breaks in spraying that exceed the potlife

???overnight shutdown or end of shift

???before servicing the fluid manifold assembly, hose or gun.

1.Press on Run Mix Spray (Screen 2) or from any screen to put the system in Standby.

2.Trigger the gun to relieve pressure.

3.If you are using a high pressure gun, engage the trigger lock. Remove spray tip and clean tip sepa- rately.

4.If using an electrostatic gun shut off the electrostat- ics before flushing the gun.

5.Set the solvent supply pressure regulator at a pres- sure high enough to completely purge the system in a reasonable amount of time but low enough to avoid splashing or an injection injury. Generally, a setting of 100 psi (0.7 MPa, 7 bar) is sufficient.

6.If using a gun flush box, place the gun into the box and close the lid.

7.Press on Run Mix Spray (Screen 2). The purge sequence automatically starts.

If the gun flush box is not used, trig- ger the gun into a grounded metal pail until the purge sequence is com- plete.

When done purging, the system automatically switches to Standby mode.

8.If the system is not completely clean, repeat step 6.

NOTE: If necessary, adjust purge sequence times so only one cycle is required.

Basic Operation

9.Trigger the gun to relieve pressure. Engage trigger lock.

10.If spray tip was removed, reinstall it.

11.Adjust the solvent supply regulator back to its nor- mal operating pressure.

NOTE: The system remains full of solvent.

NOTE: If your system uses 2 guns, you must trigger both guns simultaneously during a purge to purge both guns and lines. Verify that clean solvent flows from each gun. If not, repeat purge or clear clog/blockage in sys- tem.

Dynamic Dosing

In typical operation (ratios 1:1 and above), component A dispenses constantly. Component B dispenses intermit- tently in the necessary volume to attain the mix ratio.

General Operating Cycle, Dynamic Dosing

Overview

Dynamic Dosing provides on-demand proportioning, eliminating the need for an integrator and therefore min- imizing undesired material contact. This feature is espe- cially useful with shear-sensitive and waterborne materials.

A restrictor injects component B into a continuous stream of component A. The software controls the dura- tion and frequency of each injection. See FIG. 52 for a schematic diagram of the process.

Dynamic Dosing System Parameters

The following parameters affect dynamic dosing perfor- mance:

???Component A Flow: Ensure that the supply pump is sized to provide sufficient and uninterrupted flow. Note that component A provides majority of system flow at higher mix ratios.

???Component B Flow: Ensure that the supply pump is sized to provide sufficient and uninterrupted flow.

???Component A Pressure: Ensure precise pressure regulation. It is recommended that the component A pressure be 5-15% lower than the component B pressure.

???Component B Pressure: Ensure precise pressure regulation. It is recommended that the component B pressure be 5-15% higher than the component A pressure.

NOTE: When using dynamic dosing it is very important to maintain a constant, well-regulated fluid supply. To obtain proper pressure control and minimize pump pul- sation, install a fluid regulator on the A and B supply lines upstream of the meters.

Select a Component B Restrictor Size

If you cannot maintain the desired flow and spraying ratio, you may need to select a different restrictor. Use the charts on pages 61 to 65 to select an appropriate restrictor size based on the desired flow and mix ratio.

Balancing A/B Pressure

If component B pressure is too high, it will push the com- ponent A stream aside during B injection. The valve will not open long enough, causing a Ratio High error.

If component B pressure is too low, it will not be injected in sufficient volume. The valve will stay open too long, causing a Ratio Low error.

Selecting the correct component B restrictor size and balancing the A/B pressures will keep the system in the proper pressure range, resulting in a consistent mix ratio.

FIG. 50 shows the A to B pressure balance, read at the proportioner inlet. It is recommended that the compo- nent B pressure be 5-15% higher than the component A pressure to keep the system in the control range, hold the proper mix ratio, and obtain properly mixed material. If pressures are not balanced (???B Pressure Too High??? or ???B Pressure Too Low???), it may not be possible to hold the desired mix ratio. The system will generate an off ratio alarm and stop operation.

NOTE: In multi-flow rate systems, it is recommended that you set up the system to run properly at the highest flow rate, to ensure adequate fluid supply across the flow rate range.

In dynamic dosing, component A dose valve is con- stantly on. Component B dose valve will cycle on and off; one cycle every 0.5 ??? 1.0 seconds indicates proper balance.

Monitor system performance by watching the pressure readings for each pump on Run Pump Control (Screen 15).

FIG. 49. Monitor Pump Pressures

Warning messages also provide information on system performance. Adjust pressures accordingly. See Table 2 on page 49.

NOTE: Do not use the fluid in the line that was dis- pensed off ratio as it may not cure properly.

System Alarms

System alarms alert you of a problem and help prevent off-ratio spraying. If an alarm occurs, operation stops and the following occurs:

???Alarm buzzer sounds.

???Status bar on the Display Module shows the alarm code.

???Alarm is saved in the date/time stamped log.

Error Code Indicator

FIG. 53. Display Module Alarm Codes

System Advisory/Record Codes

TABLE 3 lists the advisory and record codes. Advisories and records do not stop operation or sound an alarm. If an advisory occurs, the Status bar on the Display Mod- ule shows the advisory icon and code. System records do not display on the Status bar. Both advisories and records are saved in the date/time stamped log, which can be viewed on the display or saved to a flash drive using optional USB port.

To Clear Error and Restart

NOTE: When an error occurs be sure to determine the error code before resetting it. If you forget which code occurred, use Run Log Errors (Screens 5-14), page 40, to view the last 50 errors, with date and time stamps.

To reset alarms, see Table 3, and Alarm Troubleshoot- ing, page 53. Many errors can be cleared by simply

pressing .

Air Flow Switch (AFS) Function

Air or Air-assisted Guns

The air flow switch (AFS) detects air flow to the gun and signals the ProMix 2KE controller when the gun is trig- gered. The gun icon on the Display Module shows spray when the AFS is activated.

If a pump fails, pure resin or catalyst could spray indefi- nitely if the ProMix 2KE does not detect the condition and intervene, which is why the AFS is so important.

If the ProMix 2KE detects through the AFS signal that the gun is triggered, yet one or both of the pumps are not running, a Dose Time Alarm (QTA1 or QTB1) occurs after 40 seconds and the system goes into Standby.

NOTE: Systems with a 45:1 pump ratio are designed for use with an airless gun. These systems contain no air flow switch and are set up so that they do not trigger a System Idle Warning.

NOTE: For airless applications with other pump ratios, the air flow switch can be disabled on Configure 2 (Screen 19).

System Errors

System Idle Warning (IDLE)

This warning occurs if the ProMix is set to Mix ,

and 2 minutes have elapsed since the system last received the air flow switch signal (gun trigger). The Gun

Idle icon is displayed. This warning is not active in systems with a 45:1 pump ratio, using an airless gun.

In applications using the AFS, triggering the gun clears the warning and you can start spraying again.

Without the AFS, triggering the gun does not clear the alarm. To start spraying again, you must press ,

then , then trigger the gun.

Dynamic Dosing Restrictor Selection Graphs

Dynamic Dosing Restrictor Selection Graphs

Use the graphs on pages 61- 65 as a guide to determine the correct restrictor size for your desired flow and mate- rial viscosity. Table 4 lists the available restrictor sizes.

Example:

Application: air spray system with a 5:1 mix ratio

Fluid Supply: 1:1 pumps at 100 psi (7 bar, 0.7 MPa)

Flow Rate: 300 cc/min at the gun

Select the Restrictor Size: choose either the 0.040 or 0.070 orifice, to ensure that the pressure differen- tial is not more than 10-20 psi (0.7-1.4 bar, 0.07-0.14 MPa), provided the fluid viscosities are similar to those tested.

???If the viscosity of component B is lower than the vis- cosity of the chart used for selection you may need to use a smaller restrictor or decrease the pressure differential.

???If the viscosity of component B is higher than the viscosity of the chart used for selection you may need to use a larger restrictor or increase the pres- sure differential.

???In systems using an air-assisted gun, if the fluid pressure of component A is higher than the compo- nent A pressure from the charts you may need to use a larger restrictor or increase the pressure dif- ferential.

Table 4: Restrictor Sizes

*These restrictors are included in Injection Kit 15U955.

???These restrictors are optional sizes, not included in the Injection Kit.
