The price of the tape is generally calculated in terms of the square, packing tape first of all we have to know the length of the tape, the width of the tape into rice, and then multiply by the width of the price per square in the price of each volume; Count the price of the box is the unit price by box volume plus the appropriate packaging costs, packing tape usually less than 10 yuan
The tape industry is usually used "yuan / square meter" to calculate the price of the tape, packing tape calculate the tape price formula "per roll tape price = width (m) * length (m) * square price." Specific tape prices need to be based on the cost of a larger floating, because BOPP film and glue are all petroleum products, packing tape the price is uncertain.
1, dilution effect. Dilute the concentration of combustibles in pressure - sensitive adhesives and the concentration of oxygen in the combustion process;
2, heat insulation effect. In the combustion process to produce bad gas or foam layer, packing tape or the formation of a layer of liquid or solid cover layer, so that the flame and oxygen isolation;
3, cooling effect. Absorbs the heat released during combustion, causes the temperature of the substance to drop, thereby preventing the polymer from degrading or cracking, packing tape interrupting the source of the volatile gas;
4, eliminate the effect. Through the passivation, to eliminate the burning process of free radicals, so that the combustion process of the chain reaction interrupted.
LED tape is mainly used in LED dot matrix block, packing tape digital tube (LED), display sealing, in the LED epoxy resin filling and high temperature curing process, from the sealing effect, transparent or green, easy to see the reflective cover Debris. The product has good chemical resistance and weatherability.packing tape After stripping, there is no residue, no leakage, and special matte effect on the surface of the product. The product conforms to ROHS environmental protection requirements, and is cost-effective. packing tape It can replace imported.
Tape glue is acrylic glue, also known as pressure-sensitive adhesive, the main component 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. packing tape Is in line with the standard thickness.
In the electrical and electronic industry can be used for high requirements of the H-class motor and transformer coil insulation bandage, high temperature coil end banding fixed, thermal resistance protection, capacitance and wire entanglement and other high temperature working conditions of the bonding insulation, Antistatic. In the circuit board manufacturing industry can be used for electronic protection paste, packing tape especially for SMT temperature protection, electronic switches, PCB board finger protection, electronic transformers, relays and other high temperature and moisture protection to protect the electronic components. Metal materials, high temperature spray paint, sandblasting coating mask surface protection, high temperature paint baking, packing tape easy to peel without leaving residual glue. My company anti-static high-temperature tape with high temperature, high tensile strength, chemical resistance, no residue, packing tape in line with ROHS environmental halogen-free advantages.
