Precautions for burn protection during hot melt adhesive particle operation: 9 essential safety lists in the workshop

Hot melt adhesive pelletsThe most common work-related injury during homework is not machine injury, butAdhesive burns caused by molten adhesive at 160-180 ℃——Adhesive glue sticking to the skin will not flow away like boiling water and will continue to release heat. The key points of protection can be summarized in one sentence:First isolate the high-temperature source, then standardize the handling of glue, and finally prepare the correct emergency response.Here are 9 lists that can be directly pasted on the workshop wall.

Before homework: 3 preparations

• Wear it properlyHigh temperature resistant gloves (recommended aramid or thickened leather), long sleeved workwear, goggles, and shorts and slippers are prohibited from entering the melt adhesive area.
• Check the equipmentThe glue pot cover, rubber hose insulation layer, and nozzle protective cover must be intact. If the rubber hose is damaged, the machine should be stopped immediately for replacement.
• Confirm temperatureCheck the set values on the work order and do not raise the temperature by 20-30 ℃ for the sake of “quick melting”. Overheating can cause injury and carbonization of the adhesive.

In homework: 4 red lines

• Add adhesive particles in moderationSingle addition should not exceed 2/3 of the pot capacity to avoid molten overflow; Slowly add along the pot wall, do not pour from a high place.
• Humidifiers are strictly prohibitedMoisture or water containing rubber particles entering the pot will instantly vaporize and splash, which is a common cause of burn accidents.
• Do not clean the nozzle with bare handsSpecial copper needles must be used in conjunction with heat-resistant gloves, and the machine must be stopped and cooled down to a safe range before operation.
• Not crossing the rubber hoseThe surface temperature of the rubber hose can reach over 150 ℃, and the walking route should be avoided. If necessary, protective grooves should be added.

After an accident: 2 emergency steps

• First rinse, then peelImmediately rinse with flowing cold water for 15-20 minutes. Do not forcefully tear off the solidified adhesive layer while it is hot, as it may peel off along with the skin.
• Seek medical attention promptly.If there are blisters or areas larger than the size of a palm, cover them with clean gauze after cooling and send them directly to the hospital. Do not apply toothpaste, soy sauce, or other folk remedies.

Choosing the right adhesive is itself a form of protection

Low price recycled materials have many impurities and poor thermal stability, requiring higher temperatures to melt, and can also emit smoke and splashes, invisibly increasing the probability of accidents. Sunlife hot melt adhesive from Guangzhou Sunlife Trading adopts a stable formula. Conventional books, magazines, and packaging models can be properly coated at 150-170 ℃, with low odor and less smoke, which can reduce the temperature setting and ventilation pressure in the workshop. We can also provide temperature suggestion cards for long-term customers, which can be posted next to the equipment for easy handover and execution.

Frequently Asked Questions

Question: Should the glue pot be kept on all the time?
Answer: Not recommended. Long term insulation will accelerate carbonization. If the shift handover interval exceeds 2 hours, it should be cooled down and put on standby to save energy and reduce coking.

Q: After being scalded, the glue has already solidified. Do you want to remove it immediately?
Answer: No. The solidified adhesive layer is now equivalent to a layer of dressing, which is more safely cooled and handled by medical personnel.
