下面介绍一下聚氨酯高压发泡机的温度控制。聚氨酯喷涂机厂家
To introduce the following pu high pressure foaming machine temperature control.
温度太高时反应剧烈不易控制，容易出现注入较大箱体的泡液性能不均一，开始注入的泡液已经发生化学反应，粘度迅速增大，后注入的泡液还未反应，导致后注入的泡液不能将先注入的泡液推到箱体发泡流程的最前端，出现箱体局部空泡现象。
Violent reactions is not easy to control when temperature is too high, prone to inject large housing bubble fluid properties inhomogeneity, began the injected fluid chemical reactions have occurred, the viscosity increases rapidly, after injection of foam fluid is not reaction, cause after injection of bubble liquid can't push the first injection of bubble liquid at the forefront of enclosure foaming process, a box body local cavitation.
黑白料在发泡前应进行恒温处理，控制发泡温度在18~25℃.，发泡设备预热炉温度应控制在30~50℃，发泡模温度应控制在35~45℃之间发泡模温度过低时，泡液体系流动性差，固化时间长，反应不彻底，出现空泡；
Should be done before black and white material in the foaming temperature, to control the foaming temperature in 18 ~ 25 ℃., foaming equipment preheating furnace temperature should be controlled in 30 ~ 50 ℃, foaming mould temperature should be controlled between 35 ~ 45 ℃ foaming mold temperature too low, bubble liquid is illiquid, curing time is long, the reaction is not complete, a cavity;
发泡模温度过高时，塑料内胆受热变形，泡液体系反应剧烈。因此，必须严格控制发泡模温度和发泡炉的环境温度。
Foaming mould at high temperature, the plastic tank heat deformation, bubble liquid is violent reactions. So we must strictly control the foaming mold temperature and the foaming temperature of furnace.
特别是冬季时，每天早上开线是必须对发泡模、预热炉、发泡炉及箱体和门体预热30分钟以上，夏季发泡一段时间后须对发泡系统进行冷却降温。
Especially during the winter, the morning line is a must for foaming foam molding, preheating furnace, furnace and endows the preheating and the hydrodynamic more than 30 minutes, summer foam after a period of time shall be of foaming system for cooling.
