5.7 Operation Steps and Procedure/试验步骤及操作方法5.7.1 Keep the controller on the “open” condition将试料出口控制柄打至拆模位置,此时试料出口呈开启状态. 5.7.2 Use supporting tool to insert the molding block into the tube, make sure it sit right onto the material EXIT location; 用细孔模棒串住细孔模,并将其放入试料出口处管内(或将细孔模从进料口放入,然后用棒将细孔模捣入试料出口处管内),将细孔模置管内,可用观镜察看安装是否妥档,并将试料控制柄打至挡料位置5.7.3 Power on to start up machine;按下 POWER 键,启动机台。 5.7.4 Set down the specific time and temperature per material type;于温度控制器及计时器设定测试所需之温度及时间(见控制面板温度设定说明及操作说明)。 5.7.5 When the temperature reach the final temperature target, feed the material into tube. (Pay attention to push down when feeding material step by step)当温度稳定在定值后，按上加料漏斗向料筒中加入试料（注意边加料边用加料棒压实） 5.7.6 Insert tamper into tube, and then move up and down until all testing material push down into tube;用捣料棒插入圆柱筒并上下移动,直到试料完全捣入圆柱筒内为止。 5.7.7 Put loading stick into tube; 然后用加压砝码棒插入圆柱筒内。 5.7.8 Choose specific loading poises per actual testing criteria;依试验规定标准要求选用适当之砝码。 5.7.9 Add chosen loading poises onto loading stick, which will be falling down slowly along with plastic material melt in some minutes; 将选用之砝码置于加压砝码棒上,数分钟后试料溶解,砝码随之缓慢下降。 5.7.10 Start to do testing: move the controller onto “TEST”location;开始测试：将试料出口控制棒移动至测试位置。 5.7.11 Melt material will flow through the molding hole and out of the tube; cool down to be solid polymer/material; 此时溶解试料会由细孔模孔径流出。 5.7.12 Set method to cut off solid polymer/material (per flow rate range),




设定切料方式:(依流率大小选定切料模式设定) 5.7.13 The forepart solid material is not considered to use for measurement to keep the accuracy of testing result; normally when we can start to cut off material by scraper when the starting line reach onto the feed gate until the ending line reach onto feed gate,此时溶解试料会由细孔模孔径流出,为求测试结果的一致性,前段融解所流出都不予采用，直到取料开始线到达进料口时,立刻将其切断,才开始计时取料,而超过取料线即不再取料(如图所示)。

5.7.14 Continue to use scraper to cut off material sample when it flow through the molding gate;开始切料,(在设定的时间内机台会自动切料)。5.7.15 To weigh the cutting samples respectively (measurement need to redo if the weight of the heaviest sample and the lightest sample is over the 10% of mean of 3 material samples;样条冷却后，分别称重（若样条中最重和最轻重量差超过三条重量平均值 10%，则试验需重做）Process flow with pictures

5.7.16 Power off/关机，停止加热5.7.17 Cleaning the testing instrument

清理仪器：切取样条后，将余料全部挤出，去掉砝码，趁热取出柱塞、口模，用软布清理干净，料筒用压料杆缠绕棉纱清理。切忌用金属物清直接清洗料筒，以防划伤料筒的内表面。（警告：因机台处于高温中，清理仪器时，请戴手套，以防烫伤）

5.8 Final judgment/结果判定5.8.1 MI (g/10min) = the sample weight (g)*600(s)/set cutting time

塑胶的流速率 MI(g/10min)=称出的重量(g)*600(秒)/设定切料时时间(s)例如：

7. Notice/注意事项7.1 Must fill the material into tube and start the trial within 5 min once the material has been dried.物料烘烤完成后需在 5 分钟内将其放入圆柱桶中并开始测试。7.2 The material should be pressed tightly by tamper when it is in the tube加料时必须使用捣料棒将料压实7.3 Warning: Please ware glovers once you clean the device.警告：因机台处于高温中，清理仪器时，请戴手套，以防烫伤
