平板硫化机工艺 Technology of plate curing press 平板在整个硫化过程中,在模具型胶面积上施加的压强不低于3MPA,无论使用何种型号的热板,整个模具面积上的温度分布应均匀,各点及各点与中心点间的最大温差不超过1相邻热板之间其对应差不超过1度在热板中心处的最大温度偏差不超过±0.5度热板温度;为了防止加热板与加压活动平台之间的热传导,最好在它们之间加上钢制隔离板或用其他方法使之尽量减少热损失,并对热板周围的通风进行适当的隔离,用于硫化橡胶物理试验所使用的模具应根据试验中所规定试样尺寸型槽模具 一次性止血带 保定水处理设备 一次性止血带 保定空压机 北京真空泵、形状以及硫化设备的有效面积来设计制造,材料采用中碳钢或不锈钢,模腔表面应镀铬或抛光,粗糙度不大于1.60模具的模盖与模底的厚度不应小于10mm,模腔表面在一般情况下,不使用隔离剂,如果需耍时可使用少量与硫化胶不产生化学作用的残留型隔离剂,适用的隔离剂有硅油或中性皂液等 During the whole curing process of the flat plate, the pressure applied on the mold rubber area shall not be less than 3Mpa. No matter what type of hot plate is used, the temperature distribution on the whole mold area shall be uniform, and the maximum temperature difference between each point and the center point shall not exceed 1 degree, and the corresponding difference between adjacent hot plates shall not exceed 1 degree, and the maximum temperature deviation at the center of hot plate shall not exceed ± 0.5 degree hot plate temperature In order to prevent the heat conduction between the heating plate and the pressurized movable platform, it is better to add steel isolation plate between them or use other methods to reduce the heat loss as far as possible, and properly isolate the ventilation around the hot plate. The mold used for the physical test of vulcanized rubber should be designed and manufactured according to the sample size, shape and effective area of vulcanization equipment Medium carbon steel or stainless steel shall be used. The surface of die cavity shall be chrome plated or polished. The roughness shall not be greater than 1.60. The thickness of die cover and die bottom shall not be less than 10 mm. Generally speaking, isolation agent shall not be used on the surface of mold cavity. If necessary, a small amount of residual isolating agent which does not produce chemical effect with vulcanizate can be used. Silicone oil or neutral soap solution can be use |
