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.
In the rapidly developing binding industry, the requirements for book binding are also increasing day by day. Therefore, many binding factories choose high-quality, non drawing, and high bonding strength hot melt adhesives. High performance hot melt adhesive has also become an important guarantee for the quality of books. For example, Sunlife book hot melt adhesive […]
What hot melt adhesive is used for book binding? Nowadays, EVA type hot melt adhesive is commonly used to stick the side of books, and PUR type hot melt adhesive is also available, but the cost of using PUR type hot melt adhesive will be slightly higher. The process of gluing the spine is as […]
Hot melt adhesive is a type of adhesive that is applied in liquid form when heated and solidifies after cooling. A carrier used for adhesives, such as water or solvents, because in reality, heat is the carrier that allows the adhesive to be applied. In addition, most EVA hot melt adhesives do not undergo any […]
The weather resistance of hot melt adhesive affects its application effect. Hot melt adhesive manufacturers need to adjust the heat resistance of hot melt adhesive according to different application environments to achieve ideal application performance. The heat resistance of hot melt adhesive is closely related to its softening point. Hot melt adhesives with good heat […]
