You may need to know 5 gallons of moisture-responsive polyurethane hot melt adhesive machine

1) avoid the use of polyurethane pur hot melt glue machine around volatile and explosive raw materials or gases, pur hot melt glue machine spraying equipment can not be stored around flammable and explosive items.

2) do not operate the hot melt glue machine without proper protection, and good insulation or good protection panel.

3) When the pur hot melt glue machine needs to be serviced, the machine must be dismantled and repaired by professionally trained personnel.

5) When the ambient temperature is lower than -20℃ or the ambient temperature is higher than 80℃, the pur polyurethane hot melt glue machine cannot be used.

6) the use of pur polyurethane hot melt glue machine occasion should ensure that there is no fast flow of air. When pur hot melt glue machine using pur glue bucket and melt glue platen exposed to fast flowing air, due to rapid cooling, will affect the hot melt glue flow of pur hot melt glue machine, and waste energy.

7)When replenishing the pur hot melt glue, check whether the pur hot melt glue barrel is deformed, and the seriously deformed pur polyurethane hot melt glue barrel should be discarded for use to avoid damaging the pressure plate of the pur hot melt glue machine.

8) at any time disassemble pur polyurethane hot melt glue machine throat, spray glue gun case, must immediately use silicone oil to seal the possible exposed pur hot melt glue to avoid wet reaction curing.

9)when not using pur polyurethane hot melt glue machine for a long time, pur polyurethane hot melt glue machine heating platen circumference should be sealed with silicone oil to protect the performance of pur hot melt glue in the glue barrel.

Pur hot melt adhesive machine in the installation of safety precautions

• the installation of the pressure plate pur hot melt glue machine, must be properly connected to an effective grounding wire. Any equipment using high-voltage electricity need to have a grounding wire, not using a grounding wire, any pur polyurethane hot melt glue machine with insulator protection on the components, there is still a risk of forming a voltage conductor, the risk of electric shock.
• According to the load required by the pur polyurethane hot melt adhesive machine and its attached peripheral equipment, check that the power cord used with insulation protection is in compliance with the regulations and that the load of the wire must be more than thirty percent above the rated power of the pur hot melt adhesive machine.
• ensure that the voltage connected to the pur polyurethane hot melt glue machine is in line with the provisions of the hot melt glue machine, generally 5 gallons of pur polyurethane hot melt glue machine using a single-phase 220v AC voltage standard, 55 gallons of wet reactive polyurethane hot melt glue machine using 380V AC power, when the voltage used is too high or too low, can not achieve the design performance of the equipment, but also may damage the hot melt glue machine When wiring the machine, make sure that the power cord is properly connected to the correct voltage power supply.
• ensure that the pur hot melt glue machine in the specified voltage operation, if the voltage used is different from the specified standard power supply, may cause the hot melt glue machine is burned.
• pur hot melt glue machine needs professional electrician to connect the power supply, there are polarities of the power supply must not be reversed, and the wiring needs to be fixed with special terminals.

Moisture-responsive polyurethane pur hot melt glue machine in the use of matters requiring attention.

• the installation and use of pur hot melt adhesive machine, shall not be placed on the body of other debris or as a cushion apparatus used.
• should ensure the use of pur hot melt glue machine environment clean, pur glue machine pressure plate shall not have not melt solids, impurities, iron chips, screws, wire heads, hard sharp objects and other solid objects.
• move or lift the polyurethane hot melt glue machine, only allow the use of its base as the handling point, not the use of pur hot melt glue machine trip cylinder, electrical box door, electrical components on the control panel or insulation pipe rubber hose for the aid of the hot melt glue machine will be lifted, non-normal handling will damage the pur hot melt glue machine spraying equipment.
• move or transport pur hot melt glue machine, must first cut off the power supply, so that pur hot melt glue machine pressure plate and the glue barrel inside the glue cooling before moving.
• pur hot melt glue machine in the transport and handling process, must always maintain the pur hot melt glue machine vertical, if tilted handling or transport will damage the positioning accuracy of the pur hot melt glue machine, may also damage the pur hot melt glue machine.

Hot melt adhesive and solvent use general safety precautions:

1. Pur polyurethane hot melt adhesive

When using high temperature pur polyurethane hot melt adhesive, and pay close attention to the following matters.

a, the hot melt adhesive can be in liquid form at high temperature quickly condensed into a solid, even in a solid state for a period of time, still with high temperature, once touching the human skin, will cause serious injury.

b. When working near the pur moisture reactive polyurethane hot melt glue machine or loading the pur hot melt glue bucket, always pay attention to whether you are wearing safe work clothes, gloves and goggles.

2.Heating cleaning solvent

a、Use heating solvent to clean the components with adhesive, do not use in the fire or no temperature control equipment for heating cleaning, general pur moisture reactive polyurethane hot melt adhesive machine in the cleaning and maintenance can not operate 280 degrees.

b. Do not use the solvent used for paint stripping to clean the components with adhesive, because this type of solvent is highly volatile, easy to burn, explosive, and at high temperatures will produce toxic gases, and easy to damage the Teflon coating on the heat platen of the pur hot melt machine.

c. Before using the cleaning solvent, you must check whether the air circulation in the room is good, avoid the use of open fire, do not clean the pur hot melt adhesive machine in an environment where there is no air circulation.

d. Try to avoid using cleaning solvent for a long time to clean pur moisture reactive hot melt adhesive machine work, so as not to inhale too much due to the high temperature below the production of potentially harmful gases.

3. The use of pur hot melt glue machine special attention.

If the skin is burned by the high temperature liquid pur hot melt glue during the use of pur hot melt glue machine, please do not try to wipe off the pur hot melt glue by the skin, and immediately soak or rinse the injured area in clean and cold water until the pur hot melt glue on the skin is completely cooled. Do not try to peel the hot melt off the skin surface. Cover the burned area with clean, moist gauze. If the injury is serious, or if the area sprayed by the hot melt adhesive is so extensive that injury or death may result or the injury may have a tendency to become inflamed, the body temperature of the injured person must be maintained at a normal state and the injured person must be taken to a hospital immediately. Therefore, we should always pay attention to safety when using pur polyurethane hot melt adhesive machine.
