各種共同的特征級HDPE的適當(dāng)組合四個基本變量:密度、分子量、分子量分布和添加劑。不同的催化劑被用于出產(chǎn)定制特別功能聚合物。這些變量結(jié)合出產(chǎn)不同用處的HDPE年級;功能到達(dá)好的平衡。
Appropriate combination of four basic variables of common characteristic HDPE: density, molecular weight, molecular weight distribution and additives. Different catalysts are used to produce customized special functional polymers. These variables combine HDPE grades that produce different uses; functions achieve the best balance.
高密度聚乙烯塑料被認(rèn)為是難以想象的。具有以下特點(diǎn):
HDPE plastics are considered unimaginable. It has the following characteristics:
1,杰出的耐磨性,耐磨強(qiáng)度是碳鋼的7倍;
1. Excellent wear resistance, wear resistance is 7 times that of carbon steel.
2、小摩擦系數(shù)、附著力好;
2. Small friction coefficient and good adhesion;
3、高沖擊強(qiáng)度、優(yōu)異的低溫耐沖擊,特別是,是高的塑料
3. High impact strength, excellent impact resistance at low temperature, especially the highest plastics.
4、優(yōu)良的化學(xué)穩(wěn)定性,除了少數(shù)的溶劑腐蝕性,常見的無機(jī)、有機(jī)的酸、堿、鹽和有機(jī)溶劑沒有腐蝕性的資料。超高分子量聚乙烯類似于聚四氟乙烯的化學(xué)穩(wěn)定性,是一種慵懶資料。
4. Excellent chemical stability, except for a few solvent corrosiveness, common inorganic and organic acids, alkalis, salts and organic solvents have no corrosive information. Ultra-high molecular weight polyethylene (UHMWPE) is a lazy material similar to the chemical stability of polytetrafluoroethylene (PTFE).
5、優(yōu)良的抗老化功能的情況下自然日光,高密度聚乙烯老化生活了50年。
5. High density polyethylene (HDPE) has been aging for 50 years under natural sunlight with excellent anti-aging function.
超高分子量聚乙烯分子量大于150萬線性聚乙烯,作為一種新型的工程塑料絕緣,絕緣泡沫管的主要特性集多種優(yōu)良功能于一身。
Ultra high molecular weight polyethylene (PE), whose molecular weight is larger than 1 million 500 thousand, is a new type of insulation for engineering plastics. The main characteristics of the insulating foam tube have many excellent functions.
