Anticorrosive tape manufacturers tell you the key to how to store and affect their service life
1. Anticorrosive adhesive tape can be wound at room temperature for construction. It has a good anticorrosive effect. The thickness of the anticorrosive adhesive tape is relatively uniform and has good adhesion. Let me talk about how to store the anticorrosive adhesive tape.
1. When storing anticorrosive adhesive tapes, we must first pay attention to how to stack them. When stacking anticorrosive adhesive tapes, do not damage the anticorrosive layer, and you can also pad soft materials between the anticorrosive layers to avoid damage to the anticorrosive layer.
一分彩2. When storing the anticorrosive adhesive tape, the temperature should be between five and thirty degrees. This temperature range is a suitable temperature for storing the anticorrosive adhesive tape, and it is better to keep away from heat sources.
3. If it is to transport anticorrosive adhesive tape, it should be prevented from being exposed to sunlight during transportation, and it should not be exposed to rain or extrusion. If it is extruded, it will deform and affect the use of anticorrosive adhesive tape.
一分彩Regarding how to store the anticorrosive adhesive tape, I believe that everyone also has a better understanding, and everyone should pay attention to it when using it.

1. Photoaging life: 200 hours of UV exposure in the laboratory is equivalent to one year of outdoor exposure. According to this theory, the anti-corrosive adhesive tape was irradiated with ultraviolet rays for 4000 hours and then the tensile strength of the anticorrosive adhesive tape was measured without change. The elongation was only reduced by 20%. Based on this, the anticorrosive life of anticorrosive adhesive tapes can reach 20 years.
2. The effect of oxygen: The anticorrosive adhesive tape forms oxygen after absorbing oxygen. The amount of oxygen can be determined by measuring the amount of oxide. Generally, when the oxygen absorption amount of the adhesive tape is 10ml / g, it has little effect on the performance of the adhesive tape. Using the more stringent required value of 7ml / g as the end of life, the Arrhenius curve was drawn. It can be seen from the curve that the service life of the adhesive tape is 42 years at 80 ° C.
一分彩3, the composite effect of heat, oxygen, water: the composite effect is considered by testing the change in the resistivity of the anticorrosive adhesive tape, and the end of life has not been reached after testing at 120 ° C for 10,000 hours. The 8 ° C half-minus criterion was used to calculate the life of the adhesive tape. That is, if the life at T1 ° C is t1, the life at T1 + 8 ° C is 0.5t1. According to the 8 ° C half-minus rule, when 1 × 104 hours at 120 ° C is converted to 80 ° C, the life is: 3.2 × 105 hours, which is approximately 36.5 years.
一分彩Summarizing the above experiments prove that the service life of anticorrosive adhesive tape is 20 years long, and it is the ideal anticorrosive protection material for pipelines.
