Direct answer:Not recommended. Different brands of rubber particle substrates and formula systems may not be compatible. Mixing them may result in reduced performance, while mixing them may cause the entire pot to become clogged and scrapped, or the nozzle to be blocked.Many factories try to switch between new and old suppliers in order to save time by simply mixing pots, but the losses from shutting down and cleaning the pots far exceed the saved glue. Guangzhou Sunlife Trading has listed the four most common pitfalls, which must be thoroughly examined before changing the adhesive.
| Step | Operation |
|---|---|
| 1. Deplete old adhesive | Use the old glue in the pot to the lowest level |
| 2. High temperature cleaning | Heat up and drain the residual adhesive according to the equipment instructions, and if necessary, use cleaning material to clean it again |
| 3 small batches of trial machines | Run the new adhesive for half an hour to confirm that there are no flocs and the bonding meets the standard |
| 4. Record parameters | Record the applicable temperature and machine speed of the new adhesive to form a work instruction |
Q: Can different models of the same brand be mixed?
Short term transition between adjacent models of the same system is generally feasible, but it is also recommended to consult the manufacturer first. Sunlife hot melt adhesive customers can directly contact the technical team to confirm compatibility.
Q: How can I save someone who has already mixed the pot and produced fluff?
Stop the machine to drain, clean the pot at high temperature, and replace the filter screen. Don’t expect to continue adding new glue to ‘dilute’ it back.
Summary: Changing suppliers does not save the step of cleaning the pot. It is necessary to first deplete the pot, then clean it, and finally test the machine, so that you can switch with peace of mind and have someone responsible for any problems.
Using hot melt adhesive particles on the same material surface will provide better quality assurance, as hot melt adhesive is always sprayed on the material surface in a molten state – this helps to generate thermal reactions and increases adhesion compared to adhesives, without using heat during the bonding process. Stable quality provides good adhesion […]
You will find hot melt adhesive everywhere in your daily life. From the furniture you sit on to the corrugated cardboard boxes containing mail at the local post office, it is not difficult to find items bonded with this popular adhesive. Companies that work with wood, fabric and foam plastics, shoe manufacturers, bookbinders and plastic […]
Proper preparation and preheating are required when using hot melt adhesive for books and periodicals to ensure smooth operation. The goal is to achieve a good bonding effect. When using EVA hot melt adhesive, the first step is to master the preparation process such as preheating and temperature control before use. 1. Add glue It […]
The quality of book binding often depends not only on the equipment and paper, but also on the binding adhesive. If a book experiences problems such as page dropping, glue peeling, stiff spine, uneven flipping, and low-temperature brittleness, it is often related to the choice of binding glue, glue temperature, paper type, and process compatibility.
