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 shall be appropriately extended or the temperature of the heating pipe shall 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 shall 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 sheet is heated unevenly, and the forming defects always appear repeatedly in the same part The thermal shielding net is used to adjust the heating state of the sheet so that all parts are evenly heated;
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 before 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 Vacuum holes shall 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, and the vacuum degree is low The vacuum hole shall be appropriately increased or the hole diameter of the vacuum hole shall be increased. If possible, the vacuum slit can be used to replace the vacuum hole;
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 vacuum tank or vacuum pump is too small and the vacuum traction is not enough. Appropriately increase the capacity of vacuum tank or vacuum pump, increase the vacuum pipe valves, and avoid sharp bends at tees and bends;
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 Insufficient pressure for pneumatic forming If the die structure conditions permit, the air pressure of 137-206pa shall be adopted, and the frame booster or plunger can also be used to assist the pressure
玉米淀粉可降解餐盒的前景
Prospect of corn starch degradable lunch box
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。节约了石油等资源,经国家检测部门检测,各项卫生理化指标均达到,是餐饮市场上普遍使用却饱受争议的“一次性餐具”的理想替代品。
The corn starch based degradable environmental protection lunch box is processed with corn starch and plant fiber as the base material, supplemented by biological polyester, polyol and other materials. Its starch content is as high as 80. It can be naturally degraded in soil and natural environment without pollution and damage to the environment. It saves oil and other resources. After testing by the national testing department, all health physical and chemical indicators have been achieved. It is an ideal substitute for the controversial "disposable tableware" widely used in the catering market.
