Polypropylene non-woven felt type epoxy coal tar cold-wrapped tape is a new type of pollution-free, non-hazardous and environmentally friendly anti-corrosion product. It is a patented product independently developed by Donghua Company.
Advantages:
1. The anti-corrosion layer has stable performance and long service life.
2. The construction is more convenient, the coating solidifies naturally, no heating equipment is needed, and it can be mechanized, semi-mechanized or manual construction.
3. The cost of coating is relatively low. Under the same rust removal conditions, its comprehensive cost (including freight, processing, loss, etc.) of all anti-corrosion materials in the area is similar to that of petroleum asphalt.
4. After more than 20 years of experience accumulation, the petroleum department has formulated a set of technical standards for epoxy coal pitch anti-corrosion from design to construction, indicating that its technology is mature and reliable.
Features:
1. The base material of the cold-wound tape is polypropylene non-woven felt. This material is a synthetic fiber with high mechanical strength and good corrosion resistance, and it does not contain wax or The thickness is uniform, so the surface of the anti-corrosion layer is smooth, the adhesion is strong, there are few pinholes, and the electrical properties and anti-corrosion properties are excellent.
2. The styling glue adopts a special formula. The anti-corrosion layer solidifies quickly and the construction period is short. It can be constructed normally all year round and solves the problem of winter construction.
3. Construction is convenient and fast. One coating can achieve the reinforced or extra-reinforced anti-corrosion layer required by China's oil and gas industry standard SY/T 0447-96, which is more labor-intensive and more convenient than using epoxy coal pitch paint plus glass cloth.
Instructions for use
1. Surface treatment;
2. Apply styling glue;
3. Wrap cold wrapping tape;

Epoxy coal pitch cold-wound tape is cheap, easy to construct, and can be obtained as soon as it is applied. After the coating is cured, it has high mechanical strength, excellent electrical and chemical properties, and can be constructed under low temperature and humid conditions. The thickness of the coating Uniform, stable construction quality, the coating has anti-corrosion, waterproof, acid and alkali resistance, impact resistance, low temperature resistance and high temperature resistance.
