Mara tape: use and precautions

Mara tape is adhesive and non-adhesive. Mara tape uses a polymer film as the base layer, and a layer of adhesive is applied to it. The adhesive tape is made of adhesive tape and imported adhesive tape ("RonifxeH" and "HHTTO", etc.).

The base layer of the Mara tape mainly bears the chemical and mechanical effects of the surrounding medium on the insulating layer, and has high electrical insulation properties and protects the pipeline from damage. "In addition to the above functions, the adhesive layer on the falling film surface can also promote the retention of the insulating layer on the protected surface of the metal, thereby sealing the overlap between the layers of the Mara tape. -Tape (such as "IInaaxo On small nexc"), the non-adhesive layer of a certain composition applied to the base layer of the film can be used in combination with a special primer applied to the pipe to play the main protective role.

According to the physical characteristics of Mara tape, the surface of the pipe must be preheated before winding the tape. Polyethylene type, one is silicone rubber type. There are two types of JI3TCAP-JIIIT tape, namely}(A "type and B burning type), which are used for corrosion protection of heat pipe sections with a pipe temperature of up to 120°C. Two layers (bearing layer and insulating layer), each layer has different strength index.

1. Mara tape should be stored in the warehouse to avoid sun and rain; do not contact with acid and alkali oil and organic solvents, keep it clean and dry, 1m away from the discovery device, and the room temperature is -15 ℃ ~ 40 ℃.

2. Mara tape should be placed in rolls, cannot be folded, and should be turned over once a quarter after long-term storage. Anti-static warning floor mara tape

3. When loading and unloading the conveyor belt, it is best to use a crane and lift it smoothly with a sling to avoid damage to the edge of the conveyor belt, and do not load and unload at will, which may cause loose rollers and loose sleeves.

The type and specification of Mara tape should be reasonably selected according to the use needs and specific conditions.

5. It is not allowed to use Mara tapes of different varieties, different specifications, models, strengths and layers together.

6. It is best to use hot vulcanizate at the conveyor belt joints to improve reliability and maintain high effective strength.

7. The diameter of the conveyor roller and the minimum pulley diameter of the conveyor belt should meet the relevant regulations.

8. Do not bend or crawl the Mara tape, keep the pulling roller, the vertical roller is flexible, and the tension should be moderate.

9. When the conveyor is equipped with baffles and cleaning devices, the wear of the Mara tape should be avoided.

10. Cleanliness is the basic condition for good operation of Mara tape. The foreign body can affect the eccentricity of the tape, the tension difference and even the fracture.
