Cellophane tape

Release date:2016-07-27 The author: Click on:

1928 in the United States, Minnesota, Sao Paulo, Richard Drew invented a transparent tape. Tape according to his efficacy points can be divided into: high temperature tape, double-sided tape, insulation tape, special tape, pressure-sensitive tape, die-cutting tape, different effects for different industry needs.


principle


Why can the zona pellucida? Of course, because it is coated with a layer of adhesive on the surface of the relationship! The earliest adhesives from animals and plants, in the nineteenth century, rubber is the main component of adhesives; and modern is widely used in a variety of polymers. Adhesives can stick things, because of their own molecules and want to connect the material between the molecules to form a bond, this bond can be firmly bonded together molecules. The composition of the adhesive, depending on the brand, different types, have a variety of different polymers.

The following are the same as the "

BOPP (Biaxially Stretched Polypropylene) Tape is an indispensable product for any business, company, personal life, the state has no perfect standard for the tape industry, and only one industry standard "QB / T 2422-1998 BOPP pressure sensitive adhesive tape ". Packing belt


Tape is in the BOPP original film on the basis of high-pressure corona after a rough surface coated with glue after the sub-divided into small rolls is our daily use of the tape. Tape glue is acrylic glue, also known as pressure-sensitive adhesive, the main ingredient is tincture. Tincture is a kind of macromolecular active substance, the temperature has a certain impact on molecular activity. Glue tincture content directly affects the use of tape. The normal adhesive tape of the initial adhesive force between ≥ 13 (steel ball) between the thickness of this tape glue is generally 22 microns. Is in line with the standard thickness.

 

Tape according to his efficacy points can be divided into: high temperature tape, double-sided tape, insulation tape, special tape - pressure-sensitive tape, die-cutting tape, anti-static tape, anti-static warning tape, different effects for different industry needs;

8 Paper tube inner diameter QB / T 2422-1998

 

9 180 ℃ peel strength normal (hot and humid aging) GB / T 2792


The use of tape


1. Seal fixed protection of various products


      2. Provide protection in the production process


3. Widely used in metal, plastic, glass, ceramics and other materials, such as structural bonding, such as electronic products, plastic parts fixed, laminated glass.

 

4. Antistatic tape is used for electrostatic sensitive products or anti-static area for warning.


5. Anti-static warning floor tape is used for anti-static area, containing the British and warning signs


Storage and maintenance of tape


1, tape should be deposited into the Treasury, to avoid the sun, rain; prohibited with acid and alkali oil organic solvent contact, keep clean and dry, from the discovery device 1m outside the room temperature between -15 ℃ ~ 40 ℃.


2, the tape should be placed in volume, not folded, storage time should be repeated for a long time once.


      3, loading and unloading conveyor belt is best to use the crane, and with a rigging rope with a smooth lifting, to avoid damage with the edge, not arrogant loading and unloading, causing loose roll sets.


4, the type of tape, specifications should be based on the use of specific conditions and reasonable selection.


5, not to different varieties, different specifications models, strength, cloth number of tape connection (with group) together to use.


6, the conveyor belt is best to use hot vulcanized adhesive, in order to improve reliability, maintain a high effective strength.

 

7, conveyor conveyor roller diameter and conveyor belt with the minimum diameter should be consistent with the relevant provisions.


8, do not make the tape snake or creep, to keep the roll, vertical roller flexibility, tension to moderate.

 

9, the conveyor is equipped with baffle and install a clean device, should avoid wear on the tape.


10, cleanliness is the basic conditions for good operation of the tape, foreign matter will affect the belt eccentric, tension differences, and even broken.


11, the use of tape found early damage phenomenon, it should promptly find the reasons, repair, to avoid the emergence of adverse consequences.
