Many customers consider the cost of purchasing glue, but not everyone considers the cost of using the wrong type of glue or whether you are using adhesive correctly. Glue is only a small part of a large-scale project, but if applied incorrectly, it may lead to production issues. Insufficient use of adhesive can lead to the following challenges.
Wasting time
If your glue formula is incorrect, it will not bond properly. Most types of industrial adhesives, including gelatin and hot melt adhesive, require heating before use and require time and effort to set before use. If you apply glue without testing and find that the adhesive is incorrect, then you have spent a lot of time applying non stick glue.
Cost of Loss
The cost of using improper glue not only wastes the adhesive, but also the substrate it is applied to.
Equipment Issues
Adhesive equipment is an investment. Most manufacturers recommend using certain adhesive formulas on their equipment to prevent carbonization or dripping. Using unexpected adhesive mixtures can slow down production speed, damage equipment, and pose safety hazards.
Efficiency issues
If the production line stops, efficiency and productivity will be directly affected. Incorrect use of glue can lead to longer drying times, messy seams, cracking, carbonization, etc., thereby hindering production.
How to choose the appropriate adhesive?
Choosing the best adhesive for your project, especially during the manufacturing process, requires attention to details. Small factors can greatly alter the functionality of glue and whether it is suitable for your application.
Before using or purchasing adhesives, please consider the following issues.
What surface are you bonding?
Glue is attached to the surfaces of two substrates to fix them together. Before application, it is necessary to consider the roughness, smoothness, porosity, coating, uncoated, cleanliness, flexibility, and size of the item you are trying to bond.
What environmental conditions exist?
Think about the entire lifecycle of your product. Environmental conditions such as temperature and humidity can affect the curing and performance of adhesives. Minor temperature changes can significantly affect the curing speed and storage life.
What types of pressure will be experienced when choosing an adhesive?
Usually, one of the most critical factors to consider when choosing an adhesive is the interfacial bonding strength between the adhesive and the substrate. Whether you choose gelatin, water-based, or hot metal PUR Or other types of adhesives, usually encounter the question: how long does it take to bond?
Water based and gelatin adhesives are highly suitable for laminating and bonding paper products, but they typically lose their adhesive strength when moisture is present. Hot melt adhesive is waterproof, but it will melt or soften at high temperatures. Each type of adhesive has its own advantages and challenges, and the conditions experienced by the product will make the production of one adhesive more useful than others.
It is strongly recommended to conduct adhesive testing before purchasing or adding it to production.
There are many factors that need to be measured, including:
Direct answer: The impact is significant. For every 10 ℃ decrease in workshop temperature,hot melt adhesiveThe actual opening time has been reduced by about 30-40%; When the relative humidity exceeds 75%, the moisture content of the paper increases, and the wetting and penetration of the adhesive will deteriorate. The performance of the same batch of […]
Why does hot melt adhesive turn black when heated? The color of hot melt adhesive itself does not change easily before and after heating, but it is not absolute in actual use. So why does a good room temperature adhesive turn black when heated and dissolved? At the production level, hot melt adhesive will undergo […]
When maintaining high-performance operation of the hot melt adhesive machine, you can take many measures to reduce downtime and improve system performance. Please remember that downtime equals production loss. 1) Apply hot melt adhesive at the correct temperature. Using the correct settings can avoid many troubles. You may also want to try using a metallocene […]
Direct answer:Hot melt adhesive particles belong to thermoplastic materials and can theoretically be melted repeatedly, but in most cases, “recycling and reuse” on the production site is not cost-effective or safe.There is only one situation that can be recycled – clean residue that has never been used on the machine and has not been contaminated; […]
