Special Requirements for Glue in High Speed Crash Lock Bottom Folder Gluer
In the high - speed and high - precision operation of a High Speed Crash Lock Bottom Folder Gluer, the glue used is not just a simple adhesive; it has several special requirements. These requirements are crucial for ensuring the quality of the cardboard boxes produced, the efficiency of the production process, and the long - term performance of the boxes.
Adhesion Strength
1.1 Immediate Bonding
The glue must be able to form an immediate bond. Given the high - speed nature of the folder gluer, cardboard pieces need to be joined quickly as they pass through the machine. For example, when the crash - lock bottom of the box is being formed, the glue should bond the edges firmly within a fraction of a second. This immediate adhesion prevents the box components from shifting during the subsequent folding and processing steps.
1.2 Long - term Durability
In addition to immediate bonding, the glue must provide long - term durability. The boxes produced may be used for storing and transporting various items, and they need to maintain their integrity over time. Whether it's a box for shipping heavy industrial parts or a consumer - product packaging box, the glue - bonded joints should not weaken or come apart under normal handling, storage, and transportation conditions.
Viscosity and Flow Characteristics
2.1 Optimal Viscosity
The glue should have an optimal viscosity. If the viscosity is too low, it may flow too freely, causing glue to spread unevenly on the cardboard surfaces. This can lead to inconsistent bonding and may even result in glue dripping, which can affect the cleanliness of the production line and the quality of the boxes. On the other hand, if the viscosity is too high, the glue may not be able to spread properly, leading to poor adhesion. The ideal viscosity ensures that the glue can be accurately dispensed by the machine's glue - application system and evenly coat the cardboard edges.
2.2 Flow in High - Speed Conditions
In a High Speed Crash Lock Bottom Folder Gluer, the glue needs to flow smoothly under high - speed application. The fast - moving cardboard and the rapid operation of the glue - dispensing nozzles require the glue to have good flow characteristics. It should be able to follow the movement of the cardboard and be applied evenly without any lumps or disruptions in the flow.
Compatibility with Cardboard Materials
3.1 Different Cardboard Types
The glue must be compatible with different types of cardboard used in the production. Cardboard can vary in terms of its composition, such as corrugated cardboard with its unique fluted structure or solid - board cardboard. Each type of cardboard may have different surface textures and chemical properties. For example, some cardboard may have a coating or sizing that can affect the adhesion of the glue. The glue should be able to bond effectively with all the cardboard types used in the folder gluer's production process.
3.2 Resistance to Cardboard Moisture
Cardboard can absorb moisture, especially during storage or in humid environments. The glue used in the High Speed Crash Lock Bottom Folder Gluer should be resistant to the moisture present in the cardboard. Moisture - sensitive glues can lose their adhesive properties when in contact with moist cardboard, leading to box failures. The glue should maintain its bonding strength even if the cardboard has a certain level of moisture content.
Drying and Curing Speed
4.1 Quick Drying
In a high - speed production environment, the glue needs to dry quickly. After the glue is applied to the cardboard, the box needs to be further processed or stacked without delay. Slow - drying glue can cause the boxes to stick together during stacking or may interfere with subsequent operations such as printing or labeling. The fast - drying property of the glue ensures a smooth and continuous production flow.
4.2 Complete Curing
In addition to quick drying, the glue must also achieve complete curing. Incomplete curing can result in a weak bond over time. The curing process should be fast enough to meet the production speed requirements while also ensuring that the glue reaches its full strength and durability.
In conclusion, the glue used in a High Speed Crash Lock Bottom Folder Gluer has multiple special requirements. These requirements cover aspects such as adhesion strength, viscosity, compatibility with cardboard, and drying and curing speed. By meeting these requirements, the glue can contribute to the production of high - quality cardboard boxes in an efficient and reliable manner.
