一分彩Adhesion of anticorrosive tape (manufactured by anticorrosive tape)
1. Although the polypropylene anticorrosive tape is a new type of anticorrosive material, it is also commonly used in cold-wound construction. On the other hand, because the polypropylene tape is more economical, let me talk about the polypropylene anticorrosive tape. What advantages.
Advantage one: The binding force between the base material and the adhesive layer of the polypropylene anticorrosive tape is relatively large, and it is precisely because of this, that there will be no degumming in the construction of the polypropylene tape.
一分彩 Advantage two: polypropylene anticorrosive tape has good water resistance, so it can resist the intrusion of air, and the anticorrosive layer will not appear aging, hardening and curing.
Advantage three: Polypropylene anticorrosive tape is safer during construction, there is no pollution, and the construction is relatively simple. Only a single layer of winding is required to complete the construction.
2. The adhesiveness of the adhesive tape is an important indicator for judging the quality of the product. This is also applicable to the polypropylene anticorrosive tape for pipeline anticorrosive products. The average consumer judges the cohesiveness of a product by hand, but is this really useful? Let ’s take a look at the practical methods recommended by our technical staff for you!
一分彩 Anticorrosive tape
Feeling the viscosity of the anti-corrosion tape by hand can be an important condition to distinguish the anti-corrosion tape, but it is by no means a determining condition, because the doped anti-corrosion tape has a very high initial viscosity when it is not volatile, but when you use the anti-corrosion tape Paste the underground pipe and then quickly pull it open to see the holding force. Repeatedly paste it several times and then touch it with your hands, and you will obviously feel that the sex is reduced.
一分彩The adhesive strength of polypropylene anticorrosive tape is based on SY / T0414-2007 standard, and has only two manifestations. They are: the adhesive force of the tape to the primer steel (peel strength) and the adhesive force of the tape to the backing material (peel strength). The data index of the former is: ≥20N / cm. The latter is divided into two cases: ≥5N / cm for backing material without release paper; ≥20N / cm for backing material with release paper.
The judgement of the adhesive force of the polypropylene anticorrosive tape cannot be judged by the touch. The scientific method is to perform a peel strength test on the finished anti-corrosion layer with a spring scale.
一分彩The test method is: use a knife ring to cut a 10 mm wide adhesive tape layer with a length greater than 100 mm. Then use a spring scale to pull away from the tube wall at an angle of 90o, and the opening speed should not be greater than 300mm / min. Then judge by reading the spring scale. Products that meet the requirements of the index are all qualified products. Otherwise, it fails.
When selecting the anticorrosive tape, you must pay attention to the width of the anticorrosive tape and the thickness of the tape. In addition, due to the large amount of impurities in the inferior anticorrosive tape, there is an imperceptible gap between the tapes when they are rolled up, so the same number of meters Under the circumstances, the volume will be relatively large, thereby deceiving consumers.
It is precisely because the polypropylene anticorrosive tape has excellent anticorrosive performance and is very convenient during construction, so it can occupy a place in all pipeline anticorrosive materials, ensuring that the anticorrosive tape can be applied to more and wider fields. ,benefit society.
