Overall trends in the foreign trade industry in 2025
Drip irrigation tape is the core product of drip irrigation system, which plays a decisive role in the operation effect of drip irrigation system. Inferior drip irrigation tape is prone to aging, cracking, flow channel blockage, large flow deviation, uneven irrigation and fertilization, and pipe burst during use, which cannot guarantee the farmland. Normal irrigation seriously affects the growth and development of crops.
Since employees can’t distinguish between the pros and cons of drip irrigation belts on their own, it will cause irreversible losses to agricultural production and water and fertilizer management. Pros and cons of drip irrigation belts will cause serious clogging of the drip irrigation belt and the rupture of the drip irrigation belt, causing water running.
How to judge the quality of drip tape
First, look at the color, usually black, uniform
The second is to look at the surface, smooth, flat, without bubbles, hanging material line deflection blocks, impurities, etc.
One is the dripper flow: It is advisable to use 1.8-2.6L/h
The distance between the emitters is generally 300-400mm, and the uniformity of the general system below 200mm is difficult to guarantee
The flow uniformity coefficient (CV) should be less than 5%;\
The anti-clogging performance mainly depends on the flow channel structure, size and water flow speed in the flow channel of the emitter. The zigzag flow channel structure is better than the Great Wall labyrinth channel;
The tensile performance is often related to the ratio of new materials. The more new materials, the better the tensile performance. The general tensile performance of drip irrigation tapes using recycled materials is generally unqualified;
The aging resistance is to ensure the normal use time of the drip tape, which mainly depends on whether the appropriate amount of high-quality carbon black and antioxidants are added.
