玉米淀粉基降解環(huán)保餐盒，是采用玉米淀粉及植物纖維為基料，輔之以生物聚酯、多元醇等物質(zhì)加工而成，其淀粉含量高可達(dá)80，在土壤和自然環(huán)境下可以自然降解，對(duì)環(huán)境沒(méi)有污染、無(wú)破害。那么您知道玉米淀粉顆粒可降解餐盒成型遇到問(wèn)題有哪些嗎？

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片材加熱時(shí)間太短或加熱器溫度太低,應(yīng)適當(dāng)延長(zhǎng)加熱時(shí)間或提高加熱管溫度

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加熱器加熱功率偏小.應(yīng)適當(dāng)加大加熱器的加熱功率

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

③片材受熱不均勻,成型缺陷總是在同一部位重復(fù)的出現(xiàn).應(yīng)用熱屏蔽網(wǎng)調(diào)節(jié)片材的受熱狀態(tài),使各部位均勻受熱

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夾片前夾持架沒(méi)有預(yù)熱,夾片前應(yīng)預(yù)熱夾持架；

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.應(yīng)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真空孔數(shù)量太少或孔徑太小,真空度偏低.應(yīng)適當(dāng)增加真空孔或加大真空孔孔徑,如有可能,可用真空窄縫代替真空孔

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,真空牽引力不夠,應(yīng)適當(dāng)增加真空罐或真空泵的容量,加大真空管閥件,在三通和彎管處避免急彎

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氣壓成型的壓力不足.應(yīng)在模具結(jié)構(gòu)條件允許的情況下,采用137——206Pa的氣壓,也可使用框架助推器或柱塞助壓

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
