Heat-sealing adhesive tape is a kind of adhesive tape which is heated by special equipment (hot air seam sealing machine or high-frequency heat sealing machine) and sewed at the needle holes of knitted bones of waterproof and air-proof series products such as raincoats, tents and lift-off balloons to achieve the sealing (waterproof and air-proof) effect.
As we all know, there will be pinholes in garment processing and production, and waterproof series is no exception. How to ensure that these pinholes don't leak water, this seemingly simple problem has also troubled us for thousands of years, because ordinary tape has no adhesion when it meets water.
But in the 20th century, only a few countries in the world used it, and the materials were very expensive. It only appears in countries with relatively developed military industries such as the United States and the Soviet Union, and it is only used in space science and technology. It is even more confidential to other countries.

May 30 1928 filed an application in Britain and the United States. Drew developed a lightweight pressure-sensitive adhesive, and later improved it and invented scotch tape.
The adhesive tape is the adhesive tape that we use every day. On the basis of the original BOPP film, it is roughened by high-voltage corona, then coated with glue, and then divided into small rolls. Adhesive tape is acrylic adhesive, also called pressure sensitive adhesive, and its main component is tincture. Tincture is a kind of polymer active substance, and the temperature has a certain influence on the molecular activity. The tincture content of glue directly affects the use of adhesive tape. The initial adhesion of normal sealant tape is ≥ 13 (number of steel balls), and the thickness of this adhesive tape is generally 22 microns, which meets the standard thickness.
For colored tape, it is convenient for marking and shielding purposes, generally beige and khaki are more. The color of colored tape is the color of glue.
Squeeze the cellophane tape tightly and then pull it away quickly, so that the glue on one side can be torn off and the purity and transparency of the original film can be seen. Insulating tape refers to the tape used by electricians to prevent leakage and play an insulating role.
Production technology: PVC film as the base material, coated with rubber pressure sensitive adhesive.
Insulating rubber tape refers to the tape used by electricians to prevent leakage and play an insulating role. Adhesive tape, also known as insulating tape, consists of baseband and pressure-sensitive adhesive layer. Baseband is generally made of cotton cloth, synthetic fiber fabric and plastic film, and adhesive layer is made of rubber and tackifying resin, which has good adhesion and excellent insulation performance. Insulating tape has good insulation and pressure resistance, flame retardant, weather resistance and other characteristics, and is suitable for wire connection, electrical insulation protection and other characteristics.
Insulating tape is widely used in electrical work, such as binding, joint and insulation sealing of wires used at 380 volts. There are two production processes: gluing and gluing. Manufacturing process: PVC film as the base material, coated with rubber pressure sensitive adhesive.
In the process of using electricity, although people have noticed that the cross-sectional area of power cord materials has an impact on the safe use of electricity, they often pay insufficient attention to the use of insulating tape for connectors. At present, the laying of power lines is becoming more and more complicated, including under wooden floors, in walls, in partitions and in damp underground or water. Improper use of insulating tape will lead to leakage and endanger personal safety. Therefore, in order to use the insulation tape correctly, the power cord connectors are divided into "+"type connection, "-"type connection and "T" type connection. The joint should be firmly wrapped, smooth and burr-free, otherwise, before disconnecting the thread end, gently press it with wire pliers, then wrap it around your mouth and swing it left and right, and the thread end will be easily disconnected at the joint. If the joint is in a dry place, first wrap 2 layers with insulating vinyl cloth, then 2 layers with plastic tape, then stretch it by about 200% with insulating self-adhesive tape, then wrap 2 ~ 3 layers, and finally wrap 2 layers with plastic tape.
Because direct use of plastic tape has many disadvantages: plastic tape is easy to open in a wrong place after a long time; When the electrical load is large, the joint is hot, and the plastic belt is easy to melt and shrink; The power connectors are pressed against each other in the junction box. When the connector has burrs, it is easy to puncture the plastic belt.
These hidden dangers will directly endanger personal safety and cause short circuit and fire. However, when using insulating black tape, the above situation will not occur. It has certain strength and flexibility, can be tightly wrapped around the joint for a long time, and can be tightly molded due to the influence of time and temperature, and will not fall off, so it is flame retardant. Furthermore, it can be moisture-proof and rust-proof by wrapping it with insulating black tape and then wrapping it with plastic tape.
Of course, the insulating self-adhesive tape also has defects. Although waterproof, it is easy to break. So finally, two layers of plastic tape should be wrapped as a protective layer, and the insulating self-adhesive tapes of the joint do not stick to each other, so the performance is better. Anti-corrosion tape refers to the tape used for anti-corrosion winding, which is divided into cold winding tape and hot winding tape. Cold winding tape
Generally, it includes polyethylene (composite) anti-corrosion tape, polypropylene reinforced fiber anti-corrosion tape, aluminum foil anti-ultraviolet anti-corrosion tape, polyethylene 660 (modified asphalt) tape, double-sided adhesive tape (this kind of tape is rarely used in China, but it is very practical and widely used abroad and is generally used for export) and epoxy coal tar pitch anti-corrosion tape. The implementation standards are SY/T04 14-98 and SY/T0447-96. Hot winding tape, also known as radiation crosslinked polyethylene heat shrinkable winding tape, can only be used when the adhesive is melted by heating, and sometimes it needs the assistance of solvent-free epoxy paint to become a three-layer structure anticorrosion. The implementation standard is SY/T04 13-2002. The shielding tape is a kind of metal foil or conductive cloth with high conductive adhesive. Its conductive adhesive and conductive substrate form a complete conductor, which can be bonded with any metal surface to complete electric lap joint and gap sealing. The shielding conductive tape is an economical and convenient shielding material.
It is used to seal the seams of EMI shielding room, shell and electronic equipment, wrap cables for shielding, provide reliable grounding surface and provide electrical contact for surfaces that cannot be welded. Name: Mara tape, also known as silicone Mara tape, fire cow tape, Mara tape.

Widely used in the construction industry and automobile industry. 1, tape should be stored in the warehouse to avoid sun and rain; It is forbidden to contact with organic solvents such as acid, alkali and oil, and keep them clean and dry. From the discovery device 1m, the room temperature is between-15℃ and 40℃
2, tape should be placed in rolls, shall not be folded, storage time is too long should be turned once every quarter.
3. When loading and unloading the conveyor belt, it is best to use a crane and lift it smoothly with rigging with beams to avoid damaging the belt edge. Don't load and unload at will, which will make the coil and sleeve loose.
4. The types and specifications of adhesive tape should be reasonably selected according to the use needs and specific conditions.
