5、降低成品儲(chǔ)庫(kù)率、節(jié)約流動(dòng)資金 Reduce the rate of storage and save floating capital,3,降低烘干成本、節(jié)省能源 Decrease the cost of drying and save energy,4,輸送帶采用網(wǎng)狀不銹鋼制輸送帶，對(duì)附著在輸送帶上的藥液具有較強(qiáng)的抗腐蝕能力，也利于沒(méi)有噴到蚊香坯上的藥液流入下方的回收池,（杜碧華）,The conveyor belt were produced with reticulate stainless steel, which have strong anti- corrosion to inse

6、cticides, and its beneficial to reflux of insecticide solution sprayed away the blank coil.,噴嘴由圓錐形改為扇形。噴出的液體為扁平扇形，在投射面上噴灑形狀為狹長(zhǎng)帶狀，當(dāng)輸送帶勻速移動(dòng)時(shí)，保證藥液噴灑均勻，也解決圓錐形噴嘴噴灑面重合、噴灑部位均勻性差的問(wèn)題,Conical nozzle were changed into fan-type nozzle. Solution were fanned out and were narrow ribbon when sprayed on the surface.

7、 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.,用藥量計(jì)算,（1）傳統(tǒng)工藝法 Production technology of mixed insecticide 以1kg工業(yè)純有效成分來(lái)計(jì)算可以生產(chǎn)得到的蚊香盤(pán)數(shù)（N）： The number of mosquito c

12、r pesticide registration,與舊國(guó)標(biāo)相比，新國(guó)標(biāo)各部分共同特點(diǎn),1. 將試驗(yàn)方法和評(píng)價(jià)標(biāo)準(zhǔn)合二為一； The test method and evaluation criteria were combined 2. 明確試蟲(chóng)：采用標(biāo)準(zhǔn)試蟲(chóng)，齡期修改為時(shí)間段； The insects were defined: standard insects were used, and ages were modified as time periods 3. 修改試驗(yàn)條件：相對(duì)濕度由原來(lái)60%5%，調(diào)整為60%10%； Testing conditions were modified

13、: Relative humidity was adjusted from the original 60%5% to 60%10% 4. 規(guī)范試驗(yàn)方法的表述方式； Description of test methods were modified 5. 增加了對(duì)試驗(yàn)結(jié)果和試驗(yàn)報(bào)告編制的要求； Requirements for test results and reports were put forward 6. 嚴(yán)格評(píng)價(jià)判斷標(biāo)準(zhǔn)，明確了有一項(xiàng)達(dá)不到B級(jí)標(biāo)準(zhǔn)，即屬于不合格產(chǎn)品； Evaluation criteria were strictly evaluated. If one item

14、of a product can not reach the B standards, it will be a substandard product. 7. 明確了試驗(yàn)觀察時(shí)限為20min，時(shí)限內(nèi)未擊倒試蟲(chóng)不再繼續(xù)觀察，并計(jì)入活蟲(chóng)。 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 alive insects,Compared

15、with the old GB, there are some common features of the new GB,與舊國(guó)標(biāo)相比，新國(guó)標(biāo)蚊香部分特點(diǎn),1. 蚊蟲(chóng)試蟲(chóng)數(shù)量由20只增加至30只； The number of test mosquitoes were increased from 20 to 30 2. 明確了在另處預(yù)先點(diǎn)燃5min后移至圓筒內(nèi)熏煙1 min； The mosquito coil was moved into a cylinder to fumigate for 1min after burning for 5 min at another place 3.

16、不再要求觀察24 h蚊蟲(chóng)死亡情況 ; The mortality of mosquitoes in 24 h was not required 4. 熏煙1 min不計(jì)入觀察擊倒的記錄時(shí)間。 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,與舊國(guó)標(biāo)相比，新國(guó)標(biāo)電熱蚊香部分特點(diǎn),1. 試驗(yàn)及試驗(yàn)觀察方法的改進(jìn)與蚊香相同； Modif

The setting followed the principle of “

18、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 recommendation. Another three observation p

19、oint were chosen equidistantly from the shortest time to the longest time. 3. 取消電熱固液蚊香試驗(yàn)方法與評(píng)價(jià)標(biāo)準(zhǔn)。 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,與舊國(guó)標(biāo)相比，新國(guó)標(biāo)模擬現(xiàn)場(chǎng)部分特點(diǎn),1. 試驗(yàn)及試驗(yàn)方法的改進(jìn)與蚊香、電熱蚊香片、電熱蚊香液部分相同； Modification of testing methods was the same as the mosquito coils, vaporizing mat and liquid vaporizer 2.
