Universal Controlled Fiberization (CF) Spray Nozzles 1 Universal Controlled Fiberization (CF) Spray Nozzles WARNING! Allow only personnel with appropriate training and experience to operate or service the equipment. The use of untrained or inexperienced personnel to operate or service the equipment can result in injury, including death, to themselves and others, and damage to the equipment. Description This manual provides setup, operation, troubleshooting, service, and parts information specific to Universal Controlled Fiberization (CF) nozzles. Universal CF nozzles deliver consistent, accurate adhesive patterns for a wide variety of hot melt adhesive spray applications. Universal CF nozzles utilize a series of twelve radially tangential air jets to oscillate a single adhesive fiber, producing high frequency patterns ranging from dense, high strength bonds to open patterns for high permeability. Universal CF nozzles feature a resilient seal for positive sealing and a recessed conical tip to reduce the likelihood of damage. These nozzles are compatible with Universal series modules. NOTE: Refer to Parts for nozzle part numbers. Refer to Nozzle Identification for an explanation of nozzle description codes. NOTE: Refer to the applicator manual for all applicator-related information and procedures.

Maintaining larger adhesive filaments will improve process stability, increase bond strength, and reduce air consumption. B: The pattern air delivery system should support 50 percent greater air flow than the maximum value stated here. C: The pattern air flow path is critical. Ensure that the pattern air supply lines are properly sized and that they are not kinked in a way that restricts air flow.

6 Universal Controlled Fiberization (CF) Spray Nozzles Operational Capability CF nozzles are available in a variety orifice sizes, including a standard size (0.018 in.) and a high-flow size (0.030 in.). Standard nozzles provide adequate performance in the majority of applications and are the default nozzle selection. Larger orifice nozzles are less susceptible to clogging and provide higher flow at lower pressure. Most production environments require a range of flow rates at a fixed material viscosity. Application requirements will determine the selection of nozzles. To aid in nozzle selection, some nozzle capabilities are shown graphically in Figures 4 and 5. Figure 4 0.018-in.

Universal Controlled Fiberization (CF) Spray Nozzles 17 Cleaning Method Oven (all-steel nozzles only) Table 1 Nozzle Cleaning Methods (contd) Procedure WARNING: Risk of explosion, fire, or toxic vapor release. Depending on the type of adhesive and/or organic solvent used with the nozzles, heating them in an oven can cause a hazardous event. Before using an oven to clean nozzles, consult with the oven manufacturer about the viability of this method and the safety risks. Follow the manufacturer's recommendations. WARNING: Use the oven heating controls to keep the oven at the desired temperature. Do not use an oven that does not have heating controls. WARNING: The heating temperature and time may need to be adjusted based on the oven type, the adhesive type, and the amount of char buildup on the nozzles. Nordson Corporation recommends testing this procedure on discarded nozzles prior to using it on good nozzles. CAUTION: Risk of equipment damage. Remove O-rings before cleaning nozzles in an oven. Failure to do so can cause a chemical reaction that will permanently damage the nozzles. a. Ensuring that O-rings have been removed from the nozzles, place them in an electric oven heated to approximately 385 _C (725 _F). Allow the nozzles to bake for approximately 3-4 hours. b. Turn off the oven and allow the nozzles to cool; then remove the nozzles. WARNING: Risk of fire. Use a heat-proof cloth to clean nozzles. Even cotton can burn in high-temperature conditions. WARNING: Risk of equipment damage. Handle nozzles carefully to avoid denting the orifices, which can degrade the adhesive pattern. c. Wipe the nozzles with a soft cloth and then gently blow air through the nozzle orifices from the mounting side of the nozzle.

18 Universal Controlled Fiberization (CF) Spray Nozzles Cleaning Nozzles (contd) 3. If there is any remaining char buildup on the nozzles, gently scrape the char from the nozzles. CAUTION! Risk of equipment damage. Use of an open torch, drill, or broach can damage a nozzle. Use only a pin-type probe to clean nozzle orifices and do not twist the probe inside the nozzle. 4. Ifcleaningofthenozzleorificesisnecessary,useapin-typeprobethatis one size smaller than the orifice size: insert the probe in the direction opposite the adhesive flow, wipe the probe, and then remove the probe without twisting it, as shown in Figure 8. NOTE: For available nozzle cleaning kits, which contain a holder and several probe sizes, refer to Parts. Figure 8 Correct direction to insert a pin-type probe into a nozzle 5. Reinstall the nozzles.

22 Universal Controlled Fiberization (CF) Spray Nozzles CF Disk and Unibody Nozzles The difference between CF disk and unibody nozzles is explained in Table 2. The nozzles may have either 6 air openings or 12 air openings. Nozzles with 12 air openings are referred to as high-frequency nozzles. NOTE: To use a CF disk or unibody nozzle with a Universal module, an adapter is required. Refer to Nozzle Adapter Part Numbers earlier in this manual for the CF adapter part number. CF Nozzle Type Disk Unibody or steel unibody Table 2 CF Disk and Unibody Nozzles Description The nozzle disk and the nozzle-retaining nut are two separate parts. The disk is held onto the module by the nozzle-retaining nut and is protected from damage because it is recessed inside the nut. The nozzle disk and the nozzle-retaining nut are a single assembly. This design makes the nozzles easier to clean because there are no recessed surfaces (as on disk nozzles). However, the nozzle disks may be more susceptible to damage. The nozzle-retaining nuts on unibody nozzles are color-coded for ease of identification. Steel unibody nozzles are also available. 1 2 Figure 12 CF disk and unibody nozzles 1.
