Classification method of adhesive products and storage method of high temperature adhesive tape

Classification method of adhesive products:
1, according to the application method can be divided into thermosetting type, hot melt type, room temperature curing type, pressure sensitive type and so on.
2, according to the application object is divided into structural, non-structural or special glue. Structural adhesives include: epoxy resin, polyurethane, silicone, polyimide and other thermosetting adhesives; Thermoplastic adhesives such as polyacrylate, polymethacrylate and methanol; Special adhesive such as high temperature resistance, ultra-low temperature, electrical conductivity, thermal conductivity, magnetic conductivity, sealing, water adhesive, etc.; There are also modified multicomponent adhesives such as phenolic - epoxy type.
3, according to the curing form can be divided into solvent volatile type, emulsion type, reaction and hot melt type four.
4. Synthetic chemists often like to classify adhesives according to the chemical composition of adhesives.
5. It is divided into organic and inorganic categories according to its main components.
6, according to the appearance of the classification, can be divided into liquid, paste and solid three categories.
7, by component classification: single component, two component, reaction type.

High temperature tape storage method:
1, high temperature tape should be stored in the warehouse, to avoid the sun, rain; It is forbidden to contact with organic solvents of acid, alkali, oil, and keep clean and dry. The room temperature is between -15℃ and 40℃ except for 1m away from the discovery device.
2, do not make the high temperature belt snake or creep, to keep the drag roller, vertical roller flexible, tensioning force should be moderate.
3, high temperature tape should be placed in rolls, do not fold, storage time is too long should be turned quarterly once.
4, the type of high temperature tape, specifications should be based on the use of needs and specific conditions, reasonable selection.
5, do not put different varieties, different specifications and models, strength, cloth layer of high temperature tape connection (matching) together.
6. Cleanliness is the basic condition for the good operation of high temperature tape. Foreign substances will affect the eccentricity, tension difference and even fracture of the tape.
7, in the use of high temperature belt found early damage phenomenon, should be timely to find the cause, repair, to avoid adverse consequences.
