Description
技术领域technical field
本实用新型属于化工制剂检测仪器技术领域，具体涉及一种农药制剂悬浮率测定仪器。The utility model belongs to the technical field of chemical preparation detection instruments, in particular to an instrument for measuring the suspension rate of pesticide preparations.
背景技术Background technique
悬浮率是衡量农药制剂中可湿性粉剂、水悬浮剂、水分散粒剂和干悬浮剂等剂型质量的重要技术指标，也是研究农药剂型时筛选制剂配方依据的最主要技术指标。如果悬浮率过低，农药在水中分散不均匀，会导致药害的发生，还会堵塞喷洒设备的喷嘴，给农药的使用带来不便。Suspension rate is an important technical index to measure the quality of pesticide preparations such as wettable powder, water suspension concentrate, water dispersible granule and dry suspension concentrate, and is also the most important technical index for screening formulation formulations when studying pesticide formulations. If the suspension rate is too low, the pesticide will be dispersed unevenly in the water, which will lead to the occurrence of phytotoxicity, and will also block the nozzle of the spraying equipment, which will bring inconvenience to the use of pesticide.
目前农药悬浮率测定方法中使用的仪器为普通250ml具塞量筒。具体测定方法是：取适量试样放入烧杯中，用少量标准硬水化开，把液体移至250ml具塞量筒中预热至30℃，再用30℃标准硬水补充道250ml，插上塞子；将量筒在1min内颠倒30次，将量筒垂直放在30℃水浴中；30min之后，用吸管在10～15s内吸出225ml(9/10容积)悬浮液，吸液时不能搅起量筒中的沉淀物，确保吸管管尖总是在液面下几毫米处；分析原试样中和量筒里的剩余25ml悬浮液中的有效成分含量，然后计算悬浮率。上述农药悬浮率测定方法的优点是主要仪器简单，只需要一个普通250ml具塞量筒和吸管，但其缺点也很多，主要是吸液时对操作人员的熟练度要求比较高，稍不小心就会发生漏吸或者吸管管尖深入液面下太多，一旦发生漏吸情况就得重新开始吸液，耽误时间，而如果吸管的管尖深入液面下太多就会扰动量筒中的沉淀物，影响测试结果的准确性甚至使测量失败；再有就是现有测定仪器不能用目测直接观察量筒中的沉淀物的多少，因而不能直接准确的判断不同试样悬浮率的高低。The instrument used in the determination method of pesticide suspension rate is common 250ml measuring cylinder with stopper at present. The specific measurement method is: take an appropriate amount of sample and put it into a beaker, dissolve it with a small amount of standard hard water, transfer the liquid to a 250ml measuring cylinder with stopper and preheat it to 30°C, then add 250ml of standard hard water at 30°C, and insert the stopper; Invert the graduated cylinder 30 times within 1 minute, and place the graduated cylinder vertically in a 30°C water bath; after 30 minutes, use a straw to suck out 225ml (9/10 volume) of the suspension within 10 to 15 seconds, and do not stir up the sediment in the graduated cylinder when absorbing the liquid Make sure that the tip of the pipette is always a few millimeters below the liquid surface; analyze the active ingredient content in the original sample and the remaining 25ml suspension in the graduated cylinder, and then calculate the suspension rate. The advantage of the method for determining the suspension rate of pesticides above is that the main instrument is simple, and only needs a common 250ml stopper measuring cylinder and a straw, but its disadvantages are also many, mainly because the operator's proficiency is relatively high when absorbing liquid, and a little carelessness will If there is leakage or the tip of the straw goes too deep into the liquid surface, once the leakage occurs, the suction must be restarted, which will delay time. If the tip of the straw goes too deep into the liquid surface, the sediment in the measuring cylinder will be disturbed. It affects the accuracy of the test results and even makes the measurement fail; what's more, the existing measuring instruments cannot directly observe the amount of sediment in the measuring cylinder by visual inspection, so they cannot directly and accurately judge the suspension rate of different samples.

By changing the diameter from large to small and scaling the volume from bottom to top, the volume of sediment in the graduated cylinder can be read directly and quickly by visual inspection, and the suspension rate of the sample can be roughly judged according to the volume of sediment. The suspension rate of different samples can be judged (no need to analyze the active ingredient content in the original sample and the remaining 25ml suspension in the graduated cylinder and calculate the suspension rate), which can save a lot of time in the screening formulation experiment.
三、本实用新型中的异形250ml量筒主体采用有机玻璃或PE材料一体成型制作，由于有机玻璃或PE材料的耐冲击性远远大于普通化学玻璃材料，几乎没有任何断裂的危险，故其使用中不易损坏，经久耐用。3.
