自潤滑超高分子量聚乙烯車廂襯板

1、耐磨性高居各類純塑料，而且隨分子量的增大而提高;UHMWPE與鋼、銅配對時容易產(chǎn)生粘著磨損，對配偶件的磨損小。使用壽命高于鋼質(zhì)，耐磨性是炭鋼及不銹鋼的3～7倍;

2、自潤滑性很好，滾動摩擦系數(shù)在塑料中較低，可以在無潤滑下以滑動或轉(zhuǎn)動的形式工作，其潤滑性比鋼和銅在有潤滑油的情況下還要好!

3、具有很強(qiáng)的吸收沖擊能和摩擦消音的性能，有摩擦噪聲小的優(yōu)點(diǎn);

4、沖擊強(qiáng)度列塑料，是現(xiàn)有塑料品種中較耐沖擊的一種，常溫沖擊強(qiáng)度可與聚碳酸酯PC媲美，而低溫沖擊強(qiáng)度甚至比聚碳酸酯PC還要好;其沖擊強(qiáng)度是ABS的8倍、PA66的10倍、POM的22倍、PBT的25倍!

5、耐疲勞性很好，耐疲勞強(qiáng)度大于50萬次;

6、分子量較大，但不飽和鍵很少，因此具有優(yōu)良的耐化學(xué)腐蝕性，能耐各類腐蝕性介質(zhì)，比如：酸、堿、鹽，也能耐各類有機(jī)溶劑;

7、耐環(huán)境應(yīng)力開裂的性能很好，是普通乙烯的200倍，抗應(yīng)力開裂時間高達(dá)4000小時;而且耐高溫蠕變性也非常好;UHMWPE的耐輻射性亦很好;

8、超耐熱性不高，熱變形溫度HD

9、電氣性能良好，較佳的電絕緣性和抗靜電性，體積電阻率>1015Ω.cm，介電強(qiáng)度為90kV/mm，介電常數(shù)2.3;

10、表面無吸附力，對任何材料都沒有粘結(jié)性，具有較低的吸水率(<0.01%);

11、具有良好的抗高能輻射性;

12、無毒、無味、無滲出物;

Performance characteristics of car lining plate:
1. Impact resistance of car liner. Polyethylene car liner has large molecular weight and tight chemical bond. Therefore, it has strong impact resistance and will not break.
2. Corrosion resistance of carriage sliding plate. Polyethylene car liner is a super high molecular organic material with strong resistance to acid and alkali.
3. The car liner is not sticky, and the blanking speed is accelerated. Why not stick the material? This is because the water absorption of the high molecular weight polyethylene sheet is particularly low, and the goods will not stick to it even if the humidity is high.
4. Corrosion resistance of carriage sliding plate. Polyethylene car liner is a high molecular organic material with strong resistance to acid and alkali.
5. The car liner is wear-resistant. Polyethylene car liner has strong abrasion resistance and can be used repeatedly.
