What kinds of problems can affect the stickiness of crepe paper tape?
1. Electronegativity of adhesive and adhesive
Electronegativity is the electrostatic force between two substances with opposite charges. And acidity material behaves generally positive point, alkalinity is behaved for negative point, according to the principle of positive and negative attraction, the word that is stuck between content and adhesive is bigger, can stick tighter.
2. Degree of difference
In fact, the difference between the PH of two substances is mainly referred to as the size of the PH PH value difference. If the difference is greater, the bond will become better.
3. High temperature
Generally speaking, under the high-temperature environment for a long time, the paper tape articles will be accompanied by time, viscosity slowly declines, but also a will affect the paper tape sticky factor.
4. Low temperature and cryogenic
The adhesive property of the tape will decrease when the temperature reaches -253 °C, which is another factor affecting the adhesive property.
5. Humidity and immersion
Moisture affects bond strength in two ways. If the paper tape in hot and humid environment, due to hydrolysis and loss of strength and hardness, serious, even liquefaction. Water will also seep into the adhesive layer, will replace the adhesive bonding interface, so when wet, adhesive strength decreases, will affect the adhesive tape.
