2、plication technology of the active ingredient of insecticides,2,3,有效成分： Active ingredient： 有机氯类 Organochlorine 氨基甲酸酯类 Carbamates 代表药剂(e.g.)： DDT、仲丁威 DDT、Fenobucarb,有效成分： Active ingredient： 拟除虫菊酯类 Pyrethroids 代表药剂(e.g. )： 烯丙菊酯Allethrin 甲醚菊酯Methothrin 富右旋反式烯丙菊酯 Rich-d-trans allethrin 右旋烯丙菊酯 D-Allethri

3、n 炔丙菊酯Prallethrin 四氟苯菊酯ransfluthrin,有效成分： Active ingredient： 新型拟除虫菊酯类 Novel Pyrethroids 代表药剂(e.g. )： 四氟甲醚菊酯 Dimefluthrin 氯氟醚菊酯 Meperfluthrin,高效、微量、安全、低毒 high efficiency、 micro-pesticide、safe、less toxicity,用药情况,Situation of insecticides,4,手工涂药 hand-made,机械喷药 machine-made,杀虫剂、原料、粘结剂、染料等按比例混合加水搅拌和匀 Ins

4、ecticides, material, binder and dye were mixed with water,冲压机上冲压成型 Moulded by punching machine,烘房烘干 Dry in the drying room,包装 Package,施药技术,盘香,5,优点：,Advantages,提高蚊香正品率、降低生产成本 Improve the rate of quality products and decrease the cost of production,1,降低杀虫药剂损耗、提高药效 Reduce pesticide loss and improve eff

5、icacy,2,降低成品储库率、节约流动资金 Reduce the rate of storage and save floating capital,3,降低烘干成本、节省能源 Decrease the cost of drying and save energy,4,6,输送带采用网状不锈钢制输送带，对附着在输送带上的药液具有较强的抗腐蚀能力，也利于没有喷到蚊香坯上的药液流入下方的回收池,（杜碧华）,The conveyor belt were produced with reticulate stainless steel, which have strong anti- corrosi

6、on to insecticides, and its beneficial to reflux of insecticide solution sprayed away the blank coil.,7,喷嘴由圆锥形改为扇形。喷出的液体为扁平扇形，在投射面上喷洒形状为狭长带状，当输送带匀速移动时，保证药液喷洒均匀，也解决圆锥形喷嘴喷洒面重合、喷洒部位均匀性差的问题,Conical nozzle were changed into fan-type nozzle. Solution were fanned out and were narrow ribbon when sprayed on

7、the surface. When the conveyor belt moved with uniform velocity, insecticide solution were sprayed evenly. This change solve the problem of conical nozzle, such as repeated spraying and uneven cover.,8,用药量计算,（1）传统工艺法 Production technology of mixed insecticide 以1kg工业纯有效成分来计算可以生产得到的蚊香盘数（N）： The number

8、 of mosquito coils from 1kg technical concentrate (N)： N=（1kg工业纯有效成分含量）（每盘蚊香中所需的有效成分含量） N=(1kg purity of technical concentrate )/(amount of active ingredient in each mosquito coil),（2）涂层工艺法 Production technology of surface-using insecticide 每盘蚊香所需杀虫剂工业纯的重量（W原药）： The amount of technical concentrate (

9、Wtc): W原药=每盘蚊香的有效成分含量工业纯有效成分含量 Wtc =(amount of active ingredient in each mosquito coil)/ (purity of technical concentrate) 每盘蚊香所需溶剂的重量（W溶剂）： The amount of solvent (Ws): W溶剂=每盘蚊香涂药总重量- W原药 Ws=the total amountof solution sprayed on the surface of mosquito coil- W原药,Calculation,9,这些过程都是在自动滴注封装机上一次性完成 T

10、hese processes are completed in the automatic infusion-packaging machine,10,电热蚊香液的施药技术关键在配药步骤 The critical step is preparation of insecticide,11,GB 13917-1992 农药登记卫生用杀虫剂室内药效试验方法,GB 17322-1998 农药登记卫生用杀虫剂室内药效评价,+,GB 13917-2009 农药登记用卫生杀虫剂室内药效试验与评价,Laboratory efficacy criterions of public health insecti

12、ealth insecticides for pesticide registration,12,与旧国标相比，新国标各部分共同特点,1. 将试验方法和评价标准合二为一； The test method and evaluation criteria were combined 2. 明确试虫：采用标准试虫，龄期修改为时间段； The insects were defined: standard insects were used, and ages were modified as time periods 3. 修改试验条件：相对湿度由原来60%5%，调整为60%10%； Testing

13、conditions were modified: Relative humidity was adjusted from the original 60%5% to 60%10% 4. 规范试验方法的表述方式； Description of test methods were modified 5. 增加了对试验结果和试验报告编制的要求； Requirements for test results and reports were put forward 6. 严格评价判断标准，明确了有一项达不到B级标准，即属于不合格产品； Evaluation criteria were strictly

14、 evaluated. If one item of a product can not reach the B standards, it will be a substandard product. 7. 明确了试验观察时限为20min，时限内未击倒试虫不再继续观察，并计入活虫。 The observation time was determined to be 20 minutes. Insects which are not knocked down within the limited time will not be observed any longer and count as

15、 alive insects,Compared with the old GB, there are some common features of the new GB,13,与旧国标相比，新国标蚊香部分特点,1. 蚊虫试虫数量由20只增加至30只； The number of test mosquitoes were increased from 20 to 30 2. 明确了在另处预先点燃5min后移至圆筒内熏烟1 min； The mosquito coil was moved into a cylinder to fumigate for 1min after burning for

16、 5 min at another place 3. 不再要求观察24 h蚊虫死亡情况 ; The mortality of mosquitoes in 24 h was not required 4. 熏烟1 min不计入观察击倒的记录时间。 The fumigated time of 1min was not counted as a record time for knockout observation,Compared with the old GB, there are some features of mosquito coils part,14,与旧国标相比，新国标电热蚊香部分

17、特点,1. 试验及试验观察方法的改进与蚊香相同； Modification of test methods were the same as the mosquito coil 2. 电热蚊香片、电热蚊香液共同修改了试验时段设置，即遵循“留首定尾中插三”的原则，也就是电热蚊香片的第一个观察时点为1 h，电热蚊香液的第一个观察时点为2 h，其最后观察时点为企业推荐的最长有效时间点，将最长与最短观察时点间的时间段等间隔插入另外3个试验观察时点； Testing period of vaporizing mat and liquid vaporizer was modified. The setti

18、ng followed the principle of “Keep the first and the last, Insert three between them”. In other words, the first observation point was 1h for vaporizing mat and 2h for liquid vaporizer respectively, and the last observation point was the longest effective time according to manufacturer recommendatio

19、n. Another three observation point were chosen equidistantly from the shortest time to the longest time. 3. 取消电热固液蚊香试验方法与评价标准。 Testing methods and evaluation criteria of solid-liquid mosquito repellent incense were canceled.,Compared with the old GB, there are some features of vaporizing mat and liquid vaporizer,15,与旧国标相比，新国标模拟现场部分特点,1. 试验及试验方法的改进与蚊香、电热蚊香片、电热蚊香液部分相同； Modification of testing methods was the same as the mosquito coils, vaporizing mat and liquid vaporizer 2. 将原
