First, give the order of disposal:Immediately lower the temperature of the glue pot by 20 ℃ → exhaust and ventilate → stop adding new glue → remove the coking glue from the pot → check if the temperature control is malfunctioning again.The essence of smoking is that the colloid exceeds the decomposition temperature and begins to pyrolyze. Continuing to harden will cause carbonization, slagging, nozzle blockage, and even trigger a smoke alarm. The complete steps for handling such issues through the Guangzhou Sunlife Business Technology Hotline are as follows.
| phenomenon | Reason | prevention |
|---|---|---|
| Continuous white smoke+burnt smell | Temperature control failure, actual overheating | Quarterly school schedule |
| Slight green smoke | Temperature close to the upper limit for long-term melting | Glue adhesive according to usage, reduce insulation level during lunch break |
| Smoke and black residue | The old coke glue in the pot is repeatedly heated | Thoroughly clean the pot once a month |
Q: Can the glue still be used after smoking?
Slight green smoke and no change in gel color can continue to be used; The adhesive strength that has turned black and thickened has significantly decreased, and it must be removed.
Q: What kind of rubber particles are not easy to smoke?
The formula with good thermal stability and complete antioxidant system allows for longer continuous melting time. Sunlife hot melt adhesive books, magazines, and sealing series all indicate the longest retention time, and operating according to the standard will not burn the adhesive.
Q: Do I need to scrap the entire pot?
Not necessarily. Clean the coke first and then take a sample for adhesive testing. If the strength is normal, the base adhesive can be retained.
Remember the mnemonic: One drop, two connections, three stops, four clearances, five verifications, burning glue and smoking can be solved on duty.
Is the problem of falling pages always blamed on glue? Perhaps milling the back is the root cause The most troublesome quality issue for printing factories is the loss of pages in book and magazine glue packaging, and many manufacturers’ first reaction is to replace themhot melt adhesive pelletsModel, glue temperature adjustment, and glue amount […]
The flowability of hot melt adhesive particles has an impact on the quality of glue and adhesive. Hot melt adhesive has poor fluidity and can also cause stretching problems or mismatch with mechanical efficiency. 1. Sol temperature; Hot melt adhesive is very sensitive to temperature, and changes in temperature can alter the structure of the […]
