立筒仓内衬玻璃钢气密技术的研究与应用,是以立简仓内衬气密性较高的玻璃钢为主的材料。是针对已建成的钢砼、砖混,砖结构的立筒仓,这些立筒仓建筑材料都为透气性材料。因而对环流薰蒸防治储粮害虫、灭疫、气控,双低、抑制霉菌繁殖等储粮安全措施均不能在仓内进行。一但出现粮情需要出仓码垛处理,时间长,费用高、效率低。天津市粮食局下达的技术指标要求达到(PT)法5分钟。通过模拟筛选采用“三脂二布”工艺,使立筒仓内部、顶部形成一个整体,约2毫米的玻璃钢层,达到压力半衰期980帕25分48秒,经用户一年的使用杀虫、灭疫效果达到100％。操作方便,满足了用户的要求。
Vertical silo lined with FRP gas-tight technology research and application, based on legislation to set up a warehouse-lined FRP-based materials. Is for the steel concrete has been built, brick, brick vertical silos, these silos building materials are breathable materials. Therefore, the fumigation of stored grain pests, epidemic prevention, gas control, double low, restrain mildew and other grain storage security measures can not be carried out in the warehouse. Once the grain needs to be discharged from the warehouse palletizing, a long time, high cost, low efficiency. Tianjin Grain Bureau issued the technical indicators required to achieve (PT) Act 5 minutes. Through the simulation screening using “three fat two cloth” technology, so that silo inside, top to form a whole, about 2 mm of glass fiber reinforced plastic, to the pressure half-life of 980 Pa 25 minutes and 48 seconds, the user a year of insecticide, killing Epidemic effect reached 100%. Easy to operate, to meet the user’s requirements.
