超高分子量聚乙烯 |
|
1.特征:
超高分子量聚乙烯(英文缩写UHMW-PE)是热塑料.它综合了所有塑料的优越性能,而耐冲击,耐磨性,耐化学腐蚀,自身润滑,吸收冲击能这五个特性乃是目前即存塑料中所有的最高数值.已成为一种引人注目的完全新型的产品,扬中市富朗橡塑有限公司在国家有关部门的大力支接下成功地研制生产出该产品,并在国内得到广泛的应用.
1 Feature:
Excced high molecular weight polyvinyl(English curtaiment UHMW-PE)be thermoplastic engineering plastics it integrative all plastics’s high-performance,but endure impulsive,anti-abrasive,endure chemistry eat away,oleiferous inhouse,absorb impulsive energy this 5 piece behavioural is now deposit that is among plastics all tiptop numerical ＆#118alue,already become 1 piece eye – catching complete new type turn-out .among Young city unctuous substance factory at country at country the department concend’s energetically support below successfully trituration produce come out this turn-out And domestic get far-reaching application.
2.主要性能:
(1).耐磨性:
耐磨是UHMW-PE的重要特性.它的耐磨性能极好,其耐磨性与分子量成正比,随着分子量增高它的耐磨性就越高.
(2)耐冲击性:
耐冲击是UHMW-PE另一重要特性.它的冲击强度非常高,它比以耐用消费品冲击著称的聚碳酸酯的冲击强度还高3-5倍,其冲击强度随分子量的增加提高.当分子量达到150万时,冲击强度达到最高值,以后随分子量增加冲击强度有所降低.
Behavioural main:
(1) wear resistance:
wearproof be UHMW-PE important I its wear resistance energy very good ,his or its wear resistance and molecular weight be in direct proportion to with molecular weight increase its wesr resistance shall get over high.chart 1 do UHMW-PE and unaccounted substance wear resistance confer.
(2).endure impulsive property:
Endure impulsive be UHMW-PE other I behavioural important its impulsive intensity high umusual,it than by endure impulsive celebrated poly-carbonic acid ester impulsive intensity still high 3-5 time,his or its impulsive intensity with molecular weight increase but raise.when molecular weight reach 150 ten thousand hour,impulsive intensity reach tiptop occurrence,latter with molecular weight increase impact against intensity somesity’s confer.
3.抗化学药品腐蚀性
UHMW-PE对化学药品非常稳定,除强氧化性外,它具有优于聚四氟乙烯的耐化学药品腐蚀性.
4.自润滑性
UHMW-PE 的磨擦系数双其它工程塑料的小,可与聚四氟乙烯相媲美,是理想的自润滑材料.
3. Anti chemicals corrosive
UHMW-PE right chemicals stable unusual,divide out powerful property outer,it have excel polytetra-fluoro-ethylene endure chemicals corrosive.
4.From unctuosity
UHMW-PE grating factor than unaccounted engineering plastics’s small,can and polytetra-fluoro-ethylene each each other setoff setoff,be true from oleiferous substance.
5.冲击能吸收性
UHMW-PE还具有优异的冲击能吸收性,冲能吸收值在所有塑料中最高,因而噪声阻尼性很好,具有优良的消音效果,
6.其它性能
UHMW-PE 还具有一些其它性能如耐低温性,卫生无毒性,不粘性,防潮性及绝缘性能.
5absorbent impulsive porprty
UHMW-PE have excellent impulsive absorbent property absorbent impulsive occurrence at all plastics tiptop thus noise hinder Buddhist nun property very good,have undeniable disappear sound result.
6.behavioural unaccounted
UHMW-PE non-negative always some behavioural unaccounted such as endure low temperature property,non toxic clean property,inadhesion moisureproof property and insulate behavioural.
