Dual Cartridge Epoxy Tools for two part epoxy systems

Structure and Composition

• Cartridge Body: Generally made of materials such as plastic or metal, it has certain strength and corrosion resistance, can withstand the pressure of the glue and prevent glue leakage. The shape of the cartridge body is mostly cylindrical, and there are different capacity specifications, with common ones being 3ml, 5ml, 10ml, 30ml, 50ml, etc.
• Piston: Located inside the cartridge body, it is used to push the glue out of the glue cartridge. The piston is usually made of elastic materials such as rubber or plastic and closely fits with the inner wall of the cartridge body to ensure that the glue can be smoothly extruded without backflow.
• Push Rod: Connected to the piston, the push rod is pushed by manual or pneumatic devices, and then drives the piston to squeeze the glue. The material of the push rod is generally plastic or metal, and its length and diameter vary according to the size and usage mode of the glue cartridge.
• Glue Outlet: Set at one end of the cartridge body, the glue flows out through the glue outlet. The inner diameter of the glue outlet will affect the glue's extrusion speed and flow rate. An appropriate inner diameter of the glue outlet can be selected according to specific dispensing requirements. In addition, the glue outlet of some glue cartridges can also be connected to accessories such as needles or mixing tubes.
• Partition Device: In the two-component AB glue cartridge, there is a partition device that stores glue A and glue B in different chambers respectively to prevent the two glues from mixing in advance before use and ensure the performance and usage effect of the glue.

Material Selection

• Plastic Materials: Common ones include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), etc. Plastic glue cartridges have the advantages of light weight, low cost, corrosion resistance, and good insulation, and are suitable for most general AB glue storage and dispensing applications, especially in some occasions that are sensitive to weight and cost, such as handicrafts making and assembly of small electronic devices.
• Metal Materials: Such as aluminum alloy, stainless steel, etc. Metal glue cartridges have high strength, can withstand high temperatures and high pressures, and can bear relatively large pressures. They are suitable for some industrial fields with high requirements for the strength and durability of glue cartridges, such as automobile manufacturing and large-scale machinery assembly. Meanwhile, metal glue cartridges also have good thermal conductivity, which has an advantage in some applications that require heating the glue to reduce its viscosity.

Application Fields

• Electronics and Electrical Appliances Industry: It is used in processes such as bonding, fixing, and sealing of electronic components, such as pasting electronic components on circuit boards and sealing wire joints. The AB glue cartridge can accurately control the glue output volume, ensure that the glue is evenly coated on the surface of electronic components, improve the bonding quality and reliability, and ensure the normal operation of electronic equipment.
• Automobile Manufacturing Industry: In the production and assembly process of automobile parts, it is widely used in aspects such as bonding of body structural parts, fixing of interior parts, and sealing of engine parts. Automobile manufacturing has relatively high requirements for the bonding strength, temperature resistance, corrosion resistance and other properties of the glue. The AB glue cartridge used in combination with the corresponding AB glue can meet these strict requirements and improve the overall quality and safety of automobiles.
• Building Industry: It can be used for work such as bonding, repairing, and sealing of building materials, such as pasting ceramic tiles, stones, wood and other materials, and repairing cracks in concrete structures. The large-capacity design and stable glue output performance of the AB glue cartridge can meet the requirements for glue usage and construction efficiency in building construction and ensure the firmness and durability of building structures.
• Crafts Making Industry: In the production and repair of crafts such as ceramics, glass, and jade, the AB glue cartridge can help craftsmen accurately control the glue usage amount, achieve fine bonding and repair work, and improve the quality and aesthetics of the crafts.

Cooperation with Other Accessories

• AB Glue Gun: The AB glue cartridge usually needs to be used in combination with an AB glue gun. The glue gun provides power for the push rod through mechanical devices or pneumatic devices, so that the glue can be extruded more evenly and stably. Different models and specifications of AB glue cartridges need to be matched with corresponding AB glue guns to ensure a tight connection and smooth operation between them.
• Static Mixing Tube: When using two-component AB glue, in order to fully mix glue A and glue B, a static mixing tube is usually connected to the glue outlet of the AB glue cartridge. The special spiral structure inside the static mixing tube can fully stir and mix the two glues to ensure the performance and bonding effect of the glue. Different models and specifications of static mixing tubes can be selected to match the AB glue cartridge according to the characteristics such as the ratio and viscosity of the AB glue.
• Needle: In some occasions that require precise dispensing, such as fine bonding of electronic components and repair of crafts, a needle can be installed at the glue outlet of the AB glue cartridge. The inner diameter of the needle is relatively small, which can more accurately control the glue output volume and the glue output position, avoiding glue waste and pollution to surrounding objects.

Precautions for Use

• ｓｅｌｅｃｔ Appropriate Models and Specifications: According to factors such as the type, ratio, viscosity, and dispensing volume of the AB glue, ｓｅｌｅｃｔ the model and specification of the AB glue cartridge that match it. If the cartridge capacity is too small, it may be necessary to frequently ｒｅｐｌａｃｅ the cartridge, which will affect work efficiency; if the capacity is too large, the long-term storage of the glue in the cartridge may affect its performance.
• Ensure Correct Installation: When installing the AB glue cartridge onto the glue gun or other equipment, make sure that the installation is firm to avoid situations such as the cartridge becoming loose or falling off during use, which may lead to glue leakage or failure to extrude the glue normally.
• Pay Attention to the Storage Conditions of the Glue: AB glue should be stored in a cool, dry, and well-ventilated place, avoiding direct sunlight and high-temperature and humid environments. Meanwhile, it is necessary to pay attention to using the glue within the expiration date. Expired glue may affect the bonding effect.
• Clean and Maintain in a Timely Manner: After using the AB glue cartridge, it should be cleaned in a timely manner to remove the residual glue and prevent the glue from solidifying and blocking the cartridge and related accessories. For reusable cartridges, the wear condition of their components should be checked regularly, and if there is any damage, it should be replaced in a timely manner.
