注意事項(Attention):
在處理或使用聚甲醛樹脂之前,一定要閱讀鈦騰公司所提供的相關材料安全資料表。聚甲醛樹脂在分解過程中產生氣體,主要是甲醛。並且,它在射出、押出或其他處理機器的機筒中分解時,還可能在機筒中引起危險的高壓積累。因此,當操作或處理聚甲醛樹脂時,必須遵守以下注意事項。 (Before process Acetal polymer (POM), please read the related MSDS which provided by TITAN PLASTICS. Acetal polymer (POM) will produce gas while it decomposing, the main is Formaldehyde. Besides, when injecting / extruding or decomposing in barrel of machine, it may lead to High-pressure accumulation, which is very dangerous. So when process Acetal polymer (POM), please obey below item:)
 
1.一旦發生機筒滯留時間超過相應限度的情況,應立即對機筒進行清洗步驟。 (When residence time in barrel is over the limit, please clean the barrel immediately.)
2.停機時,將機筒中的樹脂全部清除,之後才能停止機統加熱器。 (While stop the machine, please clean all the resins in barrel, then stop the barrel heater.)
3.清洗材料只能選用無色聚乙烯、透明聚苯乙烯或POM原料專用清洗劑。不要使用任何其他樹脂。清洗出的樹脂應當立即浸沒在水中,以免造成工作環境中的空氣污染。 (Please only use Colorless polyethylene , Transparent polystyrene or dedicated cleaners for POM to clean. Do not use any other resin. To avoid the air pollution in workplace, the cleaning out resins should be immersed in water immediately.)
4.不要將聚甲醛樹脂規定之外的染料或添加劑相混合,也不要將不同的樹脂或不同等級的樹脂相混合。這樣會降低聚甲醛樹脂的熱穩定性,造成分解。 (Do not mix POM with Dye / additive which is not appropriate, and do not mix with different resins or different grade resins. It will lower the thermal stability of POM, and Decomposing easily.)
5.應當保證機筒、噴嘴、熱流道及其他高溫區域中沒有局部的樹脂滯留,因為它會導致樹脂燃燒或分解。如果發生滯留,應當立即通過安全、徹底的清洗以持去所有的滯留樹脂。 (Keep Barrel, nozzle, hot runner and other high temperature zone not remain any resin. It may result in Combustion or decomposition of resin. If it happens, please clean the remained resin with safe and complete way immediately.)
6.應當隨時提供充分的局部或總體通風,以保持一個安全的工作環境。 (Providing adequate ventilation at any time, keep safe workplace.)
