In addition, the dispensing syringe is divided into single liquid and double liquid. When selecting, we should also consider the glue properties, viscosity and chemical properties of glue, as well as the applicable use scenarios. For example:

1. Low temperature epoxy adhesive: this product is used for low temperature heat curing, and can form a good bonding force of zui between various materials. Improve the working performance of the product, with high stability; Its use method is also particular: A. It needs to be refrigerated in the freezer at 0~- 5 ° C; B. When using, it needs to be placed at room temperature for temperature recovery, and it needs to be used at room temperature to prevent high temperature; (Generally, the operating temperature is 60~80 ° C.)

2. UV glue: also known as photosensitive adhesive and UV curable adhesive, it is a kind of adhesive that can be cured only by ultraviolet light. It has strong bonding performance, fast curing speed and environmental protection, so it is very versatile and has a wide range of applications. UV glue has developed rapidly in electrical and electronic applications. With the continuous development of science and technology, it has huge potential. Its application scenarios cover: medical supplies, glass and handicrafts, jewelry industry, electrical and electronic industry, optoelectronics, information industry, etc.

3. PUR hot melt adhesive: hot melt adhesive is also called moisture curing reactive polyurethane hot melt adhesive (PUR); It has excellent adhesive strength, temperature resistance, chemical corrosion resistance and aging resistance. The important thing of Zui is environmental protection; Now it is widely used in packaging, wood processing, automobile, textile, electromechanical, aerospace and other national economic fields.

4. Acrylic structural adhesive: acrylic structural adhesive is a structural adhesive composed of synthetic acrylate and modified curing agent, and does not require surface treatment. At the same time, it has strong adhesive force, fast curing speed, simple cao operation and impact resistance, and is widely used for bonding metal, plastic, composite material shells, such as notebook computers and mobile phone parts (shells, batteries, etc.).

5. 300G UV tube: according to different types of glue, different types of syringe can be selected more effectively to ensure the quality of glue used. 300CC large capacity dispensing syringe is suitable for a large number of dispensing operations, reducing the number of times of glue loading, and improving the efficiency of operations. It can be directly used as a syringe to dispense glue. When using, the glue is discharged clean. When feeding, a feeding nozzle and a pressure regulating device should be added. Feeding is very convenient. The glue position can be seen. It is applicable to all kinds of glue.

Junze Dispensing Needle Cartridge is made of PP, which is more stable and flexible, and is not easy for chemical products to produce effects; When we use the piston made of PE with the needle cylinder, the design of double scrapers can make it work closely to ensure that the liquid is ejected smoothly without residue. If necessary, the dispensing syringe can be purchased from Shenzhen Jingding Packaging Materials Co., Ltd.
