沙伯基礎(chǔ)PPO
成型工藝
1) 非結(jié)晶料、吸濕小,PPO的吸水率很低,但水分會(huì)使制品表面出現(xiàn)銀絲、氣泡等缺陷,為此,可將原料置于80~100℃的烘箱中,干燥1-2h后使用。
2)PPO的分子鍵剛性大,玻璃化轉(zhuǎn)化溫度高,不易取向,但強(qiáng)迫取向后很難松弛。所以制品內(nèi)殘余內(nèi)應(yīng)力較高,一般要經(jīng)過后處理。
3)PPO為無定型材料,在熔融狀態(tài)下的流變性接近于牛頓流體,但隨溫度的升高偏離牛頓流體的程度越大。
4)PPO熔體的粘度大,因此加工時(shí)應(yīng)提高溫度,并適當(dāng)提高注射壓力,以提高充模能力。
5)PPO的回料可重復(fù)使用,一般重復(fù)使用3次,其性能沒有明顯降低。
6)對(duì)PPO熔體宜采用螺桿式注塑機(jī)成型,噴嘴采用直通式為佳,孔徑為3-6mm
7)在PPO注塑成型時(shí),宜采取高壓、高速注射,保壓及冷卻時(shí)間不能太長。
8)模具的主流道宜采用較大的錐度或采用拉料鉤,澆道以短粗為好。
9)澆口宜采用直接式、扇形或扁平形,采用針狀澆口時(shí)直徑應(yīng)適當(dāng)加大,對(duì)于長澆道可采用熱流道結(jié)構(gòu)。
10)PPO的成型收縮率較小,一般為0.2%一0.7%,因而制品尺寸穩(wěn)定性能優(yōu)良。
11)流動(dòng)性差,為類似牛頓流體,粘度對(duì)溫度比較敏感,制品厚度一般在0.8毫米以上。極易分解,分解時(shí)產(chǎn)生腐蝕氣體。宜嚴(yán)格控制成型溫度,模具應(yīng)加熱,澆注系統(tǒng)對(duì)料流阻力應(yīng)小。
12)聚苯醚的吸水率很低0.06%左右,但微量的水分會(huì)導(dǎo)致產(chǎn)品表面出現(xiàn)銀絲等不光滑現(xiàn)象,最好是作干燥處理,溫度不可高出150℃,否則顏色會(huì)變化。
13)聚苯醚的成型溫度為280-330℃,改性聚苯醚的成型溫度為260-285℃。 PPO塑膠原料注塑工藝熔料溫度:270-290℃
