中亚灌溉研究所生产联合体研制了一种泡沫塑料地下灌溉浸润装置,其压强在5—6毫帕范围内,渗漏系数为0.4—0.5米/昼夜。合成泡沫塑料的主要成分为脲基甲醛树脂(30—35)％,新月沙丘沙(40—45)％,盐酸苯胺(4—4.2)％,磷石膏(10—11)％等。浸润器制做过程是先将泡沫塑料合成物倒进金属模型,在室温条件下保持15分钟使材料发泡并硬化。这种浸润装置具有很好的孔隙结构能满足地下浸润灌溉的要求。
The Central Asia Irrigation Institute Production Consortium has developed a foam underground infiltration device with a pressure in the range of 5-6 mPa and a leakage factor of 0.4-0.5 m / day and night. The main components of the synthetic foam urea-formaldehyde resin (30-35)%, crescent dune sand (40-45)%, aniline hydrochloride (4-4.2)%, phosphogypsum (10-11)% and so on. The infiltrant was made by pouring the foam composition into a metal mold and allowing the material to foam and harden at room temperature for 15 minutes. This infiltration device has a good pore structure to meet the underground infiltration irrigation requirements.
