Many masters feel that “keeping the glue pot on is the most electricity consuming”, so they frequently switch it on and off. actuallyRepeated cold start consumes more power and damages equipment than insulationBelow are three common misconceptions.
The glue pot isThermostat ControlAfter reaching the set temperature, only continue heating when the temperature drops, and the insulation power is usually only 10-30% of the rated heating power. Taking a 5L glue pot as an example, the insulation is about 0.3-0.6kW · h/hour, not the entire 2-3kW burning process.
The next day, Cold Start needs to melt the entire pot of glue from room temperature to 160 ℃ again,The power consumption of a single cold start is often equivalent to several hours of insulationAnd the thermal shock accelerates the aging of the seal and heating tube. It is recommended to keep the insulation overnight (or set a low-temperature standby) for continuous production.
Overheating will only increase carbonization, smoking, and power consumption,Not significantly speeding upSet the most economical temperature according to the recommended temperature for adhesive particles (150-170 ℃ for books and magazines, 140-160 ℃ for sealed boxes).
| method | effect |
|---|---|
| Insulation for continuous production/by | Compared to frequent cold start, it saves energy and protects equipment |
| Set according to the recommended temperature without exceeding the temperature limit | Reduce carbonization and electricity consumption |
| Off peak capacity reduction/insulation cover | Reduce heat loss |
Rubber particles with good fluidity and moderate melting point (such as Sunlife hot melt adhesive universal type for books and magazines) heat up quickly, are not easy to carbonize, and are more cost-effective in the long run than “high melting point hard firing”. Guangzhou Sunlife Trading can provide insulation recommendations based on the capacity of your glue pot.
Q1: Should we close if we don’t produce on weekends?
It is recommended to close, but reserve time for adhesive glue during the cold start on Monday and do not force acceleration.
Q2: How many insulation gears are suitable?
A temperature 20-30 ℃ lower than the working temperature is sufficient, which not only prevents adhesive bonding but also saves electricity.
What should I do if the hot melt adhesive particles are not firmly attached to the coated paper? Direct answer: The root cause of the poor adhesion of laminated paper is mostly due toLow membrane surface energy, glue not eating paper fibers, poor coordination between opening time and compressionThese three points. The surface of laminated […]
The role and key elements of bookbinding adhesive in binding are the key to the quality of bookbinding! Hot melt adhesive becomes brittle when cooled, the back adhesive layer is not smooth, and insufficient penetration of the adhesive liquid leads to non stick properties. These are the issues that most books and publications face when […]
Adhesive failure Adhesive joints exhibit incomplete continuity in construction, which often makes them the focus of stress concentration. Under the combined action of external forces and environmental stress, joints are prone to damage. The failure strength of a joint, which refers to the maximum load that a unit of bonding area or length can withstand, […]
It is crucial to choose the appropriatehot melt adhesivefor each application. The adhesive required to complete a specific task may vary greatly, so it is important to understand which adhesive is most suitable for your application. The five commonly used types of main polymer substrates are the main components of our paper boxes and box […]
