阐述了三聚氰胺-甲醛制品的生产加工工艺。 分析并试验研究了成型时间、排气次数、表面罩光和产品器型对甲醛迁移量的影响。 结果表明:相同原料加工的仿陶瓷餐具,在允许的成型时间和温度范围内,甲醛迁移量随时间的延长和温度的升高而降低;纯三聚氰胺-甲醛树脂罩光后甲醛迁移量降低;不同器型的甲醛迁移量不同。

The production technology of melamine-formaldehyde product was elaborated. The influence of molding time, exhaust frequency, surface vanished coating and product type on formaldehyde migration was analyzed through experiment. The results showed that formaldehyde migration quantity decreases with prolonging of time and rising of temperature for the same raw materials of melamine-formaldehyde product in allowable molding time and temperature range; formaldehyde migration quantity of pure melamine-formaldehyde resin with vanished coating is lower than these without vanished coating; formaldehyde migration quantity varies with product shape.
