Glue classification

Glue is a substance that can bond two objects. Glue does not exist independently, it must be applied between two objects to play the role of bonding. The following is a brief introduction to the following types of glue and their quality identification tips.

According to the main adhesive properties of adhesives:
1. Animal glue; 2. Vegetable glue; 3. Inorganic materials and minerals; 4. Synthetic elastomer; 5. Synthetic thermoplastic material; 6. Synthetic thermosetting material; 7. Thermosetting, thermoplastic material and elastomer compound.
According to the physical form of adhesive:
1. The code for solvent-free liquid is 1; 2 The code for organic solvent liquid is 2; 3 The code for water-based liquid is 3, 4 The code for paste and paste is 4, 5 The code for powder, granule and block is 5; 6 tablets , Film, mesh, ribbon code is 6; 7 filament, strip, rod code is 7.

Classified by adhesive hardening method:
The low temperature hardening code is a; the normal temperature hardening code is b; the warming hardening code is c; the hardening code is d for a variety of temperature regions; the curing code is e; the anaerobic curing code is f; the radiation (light, electron beam , Radiation) The curing code is g; the hot melt cold hardening code is h; the pressure-sensitive adhesive code is i; the coagulation or coagulation code is j, and the other codes are k.

According to the classification of adhesives:
The code for many types of materials is A; the code for wood is B; the code for paper is C; the code for natural fibers is D; the code for synthetic fibers is E; the code for polyolefin fibers (excluding E) is F; the code for metals and alloys is G; difficult The code name for sticky metals (gold, silver, copper, etc.) is H; the code name for metal fibers is I, and the code name for inorganic fibers is J; the code name for transparent inorganic materials (glass, gemstones, etc.) is K; the code name for opaque inorganic materials is L; the code name for natural rubber is M; synthetic rubber code is N; hard-stick rubber (silicon rubber, fluorine rubber, butyl rubber) code is O, hard plastic code is P, plastic film code is Q; leather, synthetic leather code R, foam plastic code It is S; difficult-to-stick plastics and films (fluoroplastics, polyethylene, polypropylene, etc.) are coded T; biological tissue bones and dentin materials are coded U; other codes are V.
