玉米淀粉基降解环保餐盒，是采用玉米淀粉及植物纤维为基料，辅之以生物聚酯、多元醇等物质加工而成，其淀粉含量高可达80，在土壤和自然环境下可以自然降解，对环境没有污染、无破害。那么您知道玉米淀粉颗粒可降解餐盒成型遇到问题有哪些吗？

The corn starch based degradable environment-friendly lunch box is made of corn starch and plant fiber as the base materials, supplemented by biological polyester, polyols and other materials. Its starch content can reach 80, which can be naturally degraded in soil and natural environment, without pollution and damage to the environment. Do you know the problems encountered in the molding of corn starch granules degradable lunch boxes?

①片材加热时间太短或加热器温度太低,应适当延长加热时间或提高加热管温度

① If the heating time of the sheet is too short or the temperature of the heater is too low, the heating time should be appropriately extended or the temperature of the heating tube should be increased

②加热器加热功率偏小.应适当加大加热器的加热功率

② The heating power of the heater is too small. The heating power of the heater should be increased appropriately

③片材受热不均匀,成型缺陷总是在同一部位重复的出现.应用热屏蔽网调节片材的受热状态,使各部位均匀受热

③ The heating of the sheet is uneven, and the forming defects always appear repeatedly at the same part. The heat shielding net is used to adjust the heating state of the sheet, so that all parts are heated evenly

④夹片前夹持架没有预热,夹片前应预热夹持架；

④ The clamping frame in front of the clip is not preheated, and the clamping frame shall be preheated in front of the clip;

⑤真空孔阻塞,真空度偏低.应清理和梳理真空孔

⑤ The vacuum hole is blocked and the vacuum degree is low. The vacuum hole should be cleaned and combed

⑥真空孔数量太少或孔径太小,真空度偏低.应适当增加真空孔或加大真空孔孔径,如有可能,可用真空窄缝代替真空孔

⑥ The number of vacuum holes is too small or the hole diameter is too small, so the vacuum degree is low. The vacuum holes or the hole diameter of vacuum holes should be increased appropriately. If possible, the vacuum holes can be replaced by vacuum narrow slots

⑦真空罐或真空泵的容量太小,真空牵引力不够,应适当增加真空罐或真空泵的容量,加大真空管阀件,在三通和弯管处避免急弯

⑦ The capacity of the vacuum tank or vacuum pump is too small, and the vacuum traction force is not enough. The capacity of the vacuum tank or vacuum pump should be increased appropriately, the vacuum pipe valves should be increased, and sharp bends should be avoided at tees and elbows

⑧气压成型的压力不足.应在模具结构条件允许的情况下,采用137——206Pa的气压,也可使用框架助推器或柱塞助压

⑧ The pressure of pneumatic forming is insufficient The air pressure of 137-206Pa shall be used, or the frame booster or plunger can be used, if the mold structure conditions permit
