Central Qi plastic cpvc supplier, Shandong Qi plastic ring, plastic ring Qi

Central Qi plastic cpvc supplier, Shandong Qi plastic ring, ring by ring Qi Qi plastic plastic. We are Shandong Central Qi Plastics Co. (www.hershey-sd.com) located at: Shandong Weifang specializes in: UPVC, CPVC pipe fittings and valves, PVDF, PP valves and other subsurface drip, drip irrigation is to be buried underground root crop activities Qi Shandong ring inside layer of plastic, irrigation water through the pores into the soil for crop uptake. In some places separated a certain distance in the plastic pipe to drill a hole, buried underground near the roots of plants for irrigation, people commonly known as "subsurface irrigation." Subsurface drip irrigation has less evaporation loss, water, power, and fertilizer, labor and yield significant benefits, etc., fruit, cotton, crops etc. can be used. The disadvantage is that when large irrigation pipe spacing is not uniform, should not be used in large or steep ground where the soil permeability. Acres for 400 yuan -1000 yuan investment. Its benefits are: water-saving 50% -60%; saving 40% -50%; yield about 30%. Excellent features UPVC pipe to PVC resin as the carrier, with the exact temperature at the time of weakening gravitational resin molecular chains, timing melting rapidly absorb the active ingredients and other additives, while Central Qi plastic, using the world famous Ca-Zn Composite Heat process stabilizer ring Qi plastic valve supplier in the molten resin is subjected to high temperatures and can capture, suppression, and hydrogen chloride absorption prolapse, and polyolefin structure of the double bond addition reaction, displacement and unstable molecule active chlorine atoms. Science thereby effectively controlling resin in a molten state and oxidative degradation of the catalytic decomposition.
