产品详细信息
塑料颗粒原料聚苯硫醚价格PPS gf60
操作条件1.处理温度
聚苯硫醚的280˚C的高熔点使其能够在300至340˚C的温度下注塑成型，这是大多数聚苯硫醚等级和应用的典型特征。然而，对于超韧性“Z”系列和聚四氟乙烯、聚四氟乙烯填充等级，建议温度略低，为290至320℃
2.模具温度
可以选择使用从室温到150˚C以上的各种模具温度。然而，为了获得最佳性能，应尽一切努力达到最大结晶度。这需要相对较高的模具温度，至少120˚C，在模具表面测量。130˚C到150˚C之间的温度是
通常推荐。较高的模具温度可确保较高的结晶度、更好的表面光洁度和减少后收缩。在模具温度较低的情况下使用，应避免模具温度达到80℃─100˚C，该温度范围可能导致脱模能力降低
3。注射速率
根据特定配方，PPS等级具有高至极高的凝结率和结晶率，这是一个循环时间非常快的特点。因此，需要高注射速率，以防止熔体在注射过程中冷却和凝固，从而形成均匀、质量差的表面。合适的填充时间范围应设定在0.5到1.5秒之间
4.注射和保持压力
鉴于推荐的高喷射速度，通常需要相应的高喷射压力。保持压力应相对较高，为50 MPa或以上。螺杆速度和背压塑化过程需要缓慢至中等的螺杆速度，以及介于1─4兆帕。如果螺杆转速和背压都很高，
可能导致玻璃纤维过度破碎，降低最终产品的机械性能
5.清除
吹扫可以很容易地完成使用高分子高密度聚乙烯吹塑

Operating Conditions
1.Processing temperature
The PPS’s sharp melting point of 280˚C enables it to be injection molded at 300 to 340˚C is typical for most PPS grades and applications. However, slightly lower temperature of 290 to 320˚C is recommended for super tough “Z” series and PTFE, poly tetra fluoroethylene filled grades.
2.Mold temperature
A wide range of mold temperatures from room temperature to over 150˚C can be selected for use. However, in order to obtain optimum properties, every effort should be made to achieve maximum crystallinity. This requires relatively high mold temperature of at least 120˚C, measured at the mold surface. Temperatures of between 130˚C to 150˚C are
normally recommended. A higher mold temperature ensures a higher degree of crystallinity, a better surface finish and reduced post-shrinkage. In the case of low mold temperature use, should be avoided the mold temperature of 80─100˚C, which temperature range may be caused reduce of mold release ability.
3.Injection rate
Depending on the particular formulation, PPS grades have high to very high setting and crystallization rates a feature which gives very fast cycle times. High injection rates are therefore necessary to prevent the melt from cooling and solidifying during the injection process, resulting in homogeneous, poor quality surfaces. Suitable filling time range should be settled from 0.5 to 1.5 seconds.
4.Injection and holding pressure
In view of high injection speeds recommended, correspondingly high injection pressures are often necessary. Holding pressure should be relatively high 50 MPa or over. Screw speed and back pressure The plastication process requires slow to medium screw speeds, and low back pressures of between 1─4 MPa. If both screw speed and back pressure are high,
excessive crushing of the glass fibers may result, reducing the mechanical properties of the end product.
5.Purging
Purging can be readily accomplished using high molecular high density polyethylene for blow molding.
