產(chǎn)品詳情
車(chē)廂襯板性能特點(diǎn):
1、車(chē)廂襯板抗沖擊。聚乙烯車(chē)廂襯板分子量大,化學(xué)鍵緊密。因此抗沖擊能力強(qiáng),不會(huì)斷裂。
2、車(chē)廂滑板抗腐蝕。聚乙烯車(chē)廂襯板是超高分子有機(jī)材料,對(duì)酸堿有極強(qiáng)的耐性。
3、車(chē)廂襯板不粘料,加快下料速度。為什么不粘料呢?這是因?yàn)楦叻肿恿烤垡蚁┌宓奈侍貏e低,貨料即使?jié)穸却?,也不?huì)粘在上面。
4、車(chē)廂滑板抗腐蝕。聚乙烯車(chē)廂襯板是高分子有機(jī)材料,對(duì)酸堿有極強(qiáng)的耐性。
5、車(chē)廂襯板耐磨損。聚乙烯車(chē)廂襯板抗磨損能力很強(qiáng),可反復(fù)使用。
超高分子量聚乙烯板突出優(yōu)異特性:
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(duì)時(shí)容易產(chǎn)生粘著磨損,對(duì)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(rùn)滑性很好,滾動(dòng)摩擦系數(shù)在塑料中較低,可以在無(wú)潤(rùn)滑下以滑動(dòng)或轉(zhuǎn)動(dòng)的形式工作,其潤(rùn)滑性比鋼和銅在有潤(rùn)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(wàn)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(kāi)裂的性能很好,是普通乙烯的200倍,抗應(yīng)力開(kāi)裂時(shí)間高達(dá)4000小時(shí);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(wú)吸附力,對(duì)任何材料都沒(méi)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(wú)毒、無(wú)味、無(wú)滲出物;
Perbance 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.
