style="font-size:14px;font-family:""> 1、填充增強(qiáng)改性將無機(jī)材料如Al2O3、氧化鎂、玻璃纖維、碳纖維、玻璃微珠、云母、滑石粉、碳酸鈣、白炭黑、鈦酸鉀等通過熔融共混加入到聚甲醛中，從而提高聚甲醛的強(qiáng)度、剛度、硬度、熱變形溫度以及尺寸穩(wěn)定性。填充增強(qiáng)類聚甲醛主要應(yīng)用于制備機(jī)械結(jié)構(gòu)復(fù)雜、薄形精密零件及工程制品。</span> </p> <p> <span style="font-size:14px;font-family:""> 2、增韌共混改性以熱塑性聚氨酯（TPU）、丁腈橡膠（NBR）、改性聚烯烴、聚酰胺、木質(zhì)纖維素等作為彈性增韌體，采用機(jī)械共混和接枝共聚的方法制成超韌性POM合金。</span> </p> <p> <span style="font-size:14px;font-family:""> 3、功能化改性提高摩擦磨損性能在聚甲醛樹脂中加入有機(jī)油或硅油、聚四氟乙烯（PTFE）或二硫化鉬，可以達(dá)到降低制品表面摩擦系數(shù)及磨損率的作用。潤滑聚甲醛適用于機(jī)械、電子電器用零件的傳動部位材料，如齒輪、滾輪、凸輪、連桿類制品。①添加PTFE、PE、UHMWPE等自身摩擦系數(shù)較低的結(jié)晶性高分子材料。②添加玻纖、碳纖等纖維狀材料。③添加硅油、礦物油、油脂等潤滑油及潤滑脂類。④添加MoS2、石墨等無機(jī)粉類潤滑材料。⑤利用接枝、嵌段等手段在POM分子鏈上引入具有潤滑性的鏈段。提高聚甲醛的耐候性在聚甲醛中加入抗氧劑及光穩(wěn)定劑可以提高聚甲醛的耐候性。</span>
