When using hot melt adhesive granules for book binding equipment, there are two options to compare: “replace adhesive after quick emptying” and “replace adhesive after thorough cleaning”. The former saves downtime, while the latter can reduce the impact of coking materials, foreign objects, and old rubber on the performance of new rubber. Sunlife hot melt adhesive recommends selecting based on product differences, equipment residue, and order requirements.
| Comparison item | Quick emptying | Disassemble, inspect and clean |
|---|---|---|
| downtime | Shorter | longer |
| Applicable Scenarios | Similar products, frequent order changes | Large differences, high residual glue, and high quality requirements |
| Main Risks | Transition of mixed glue and residual coke particles | Improper operation leading to equipment damage |
Guangzhou Sunlife suggests recording the type of old adhesive, equipment structure, and residual adhesive performance first. Similar products and frequent order changes can be prioritized for rapid verification and emptying; When there are particles, blockages, color pollution, viscosity fluctuations, or significant product differences, thorough cleaning should be arranged and operated by trained personnel.
After adding new glue, it is necessary to check the melting state, glue supply stability, wire drawing, glue uniformity, and finished product strength, rather than just checking whether the glue tank has been changed to a new color. Safe cooling, heat-resistant protection, and cleaning according to equipment instructions are equally important.
Q: Can different brands of rubber granules be directly mixed?Answer: Not recommended, at least compatibility and device temperature window should be verified first.
Q: When must it be thoroughly cleaned?Answer: When there are burnt particles, blockages, color pollution, viscosity fluctuations, or significant product differences.
Q: Can Sunlife hot melt adhesive provide advice on changing adhesive?Answer: Verification ideas can be provided based on equipment structure, old adhesive type, and new adhesive samples.

What is EVA hot melt adhesive? This article discusses the material of heat clearing adhesive (using Sunlife EVA system as an example) from its chemical composition, principles of thermoplastic curing to its practical applications in book and magazine packaging.
The true cause of blistering on the spine of a book The appearance of bubbles (visible bulges or internal cavities) on the spine of the adhesive book is a quality taboo, and customers will directly judge it as unqualified. Many people think that foaming is a problem with the glue coating process, but in realityhot […]
The biggest fear when buying hot melt adhesive is that if it looks similar, it will drop on the machine. To judge quality, there are four key factors: particle appearance, melting state, machine performance, and accompanying documentation. You can inspect it yourself upon arrival.
