2、耐疲勞性、彈性及耐蠕變性對于長期的反復(fù)應(yīng)力具有很好的耐疲勞性和彈性的KEPITAL-與各種齒輪類、板彈類、線圈彈性彈簧、偏心輪、扣具部件等結(jié)構(gòu)零件一起，在反復(fù)應(yīng)力、彎曲、沖擊、振動等條件下仍具有耐疲勞特性。pom聚甲醛比其它塑料具有更加不錯的耐疲勞特性，它是用于受到反復(fù)應(yīng)力的零部件上的非常適合的材料。 </p> <p> 3、耐磨損性耐摩擦磨損性和耐疲勞性、耐蠕變性一樣是pom的主要特性之一。 </p> <p> 4、耐氣候性在室外或有紫外線場所被使用時，若非極端條件，南京白色pom棒批發(fā)，使用標(biāo)準(zhǔn)牌號即可滿足要求。如果需要經(jīng)常處于極端環(huán)境溫度中，推薦使用耐氣候牌號。 </p> <p> 5、尺寸穩(wěn)定性pom材料成型品具有在常溫下長期使用也能維持極高的尺寸穩(wěn)定性的特性。成型后的收縮，根據(jù)其模具溫度有所差異。但此過程1-2小時開始至2-3天之內(nèi)完成。收縮結(jié)束后在常溫下放置一年以上，其尺寸也基本不變。所以也能用于精密度要求極高的配件上。另外，在極低的溫度和潮濕的環(huán)境中，南京白色pom棒批發(fā)，尺寸變化極小，南京白色pom棒批發(fā)。

模具溫度：標(biāo)準(zhǔn)模具溫度是60-80℃，根據(jù)成型品的特性，表面狀態(tài)、使用中尺寸的變化、成型周期等要求不同，需要調(diào)節(jié)模具溫度。有時為降低成型周期，將模具溫度設(shè)定在30-40℃,但容易留下殘留應(yīng)變及得不到好的外觀。</span> </p><p><span style="font-size:14px;font-family:";">3. 注射壓力：應(yīng)考慮樹脂的流動性，收縮性，成型品的物性等進(jìn)行設(shè)定。一般為98MPa以上。保壓壓力為49-98MPa。</span> </p><p><span style="font-size:14px;font-family:";">4.

style="font-family:"font-size:14px;"> P</span><span

</p><p><span style="font-family:"font-size:14px;"> </span><span style="font-family:"font-size:14px;">POM-H+PTFE（深棕色）：POM-H+TF是用杜邦POM（DELRIN）原料加PTFE（鐵氟龍）纖維擠出而成。它保留了POM-H的大多數(shù)固有強度。因填加PTFE（鐵氟龍）纖維而有某些性能改變，稍軟，剛性小，比純的聚甲醛樹脂更滑。與純POM板比較，該種材料潤滑性更好。用POM-H+PTFE制造的軸承摩擦系數(shù)低，耐磨，并且基本無蠕動現(xiàn)象。</span>
