  塑料是一种塑料合成高分子材料。它是由合成橡胶和合成纤维制成的
  Plastics is a synthetic polymer material of plastics. It is made of synthetic rubber and synthetic fibers.
  当今生活中不可缺少的三种合成材料。具体来说,塑料是以天然或合成树脂为主要成分,加入各种添加剂,在一定的温度和压力条件下可以成型成一定的形状,在室温下可以保持相同材料的形状。
  Three kinds of synthetic materials are indispensable in today's life. Specifically, plastics are made of natural or synthetic resins as the main ingredients, adding various additives, under certain temperature and pressure conditions can be shaped into a certain shape, at room temperature can maintain the shape of the same material.
  与金属、石材、木材相比,塑料制品具有成本低、可塑性强的优点,在国民经济中得到了广泛的应用。塑料工业在当今世界占有极其重要的地位。多年来,世界各地塑料制品的生产一直在高速发展。根据数据统计的“2013 - 2017中国塑料制品行业产销需求与投资预测分析报告”,中国的塑料制品产量总是在世界排名的前列,其中多种塑料制品的产量一直在第一个在世界上的地位,中国已成为世界上最大的塑料制品生产的国家。2001年至2010年,中国塑料制品年增长率超过15%,2010年塑料制品总产量达到5830万吨。
  Compared with metal, stone and wood, plastic products have the advantages of low cost and strong plasticity, and have been widely used in the national economy. Plastic industry occupies an extremely important position in today's world. Over the years, the production of plastic products around the world has been developing at a high speed. According to the statistics of the "2013-2017 China Plastic Products Industry Production and Marketing Demand and Investment Forecast Analysis Report", China's plastic products output is always in the forefront of the world, among which the output of a variety of plastic products has been the first in the world, China has become the world's largest plastic products production country. From 2001 to 2010, the annual growth rate of plastic products in China exceeded 15%. In 2010, the total output of plastic products reached 58.3 million tons.
  在需求方面,我国人均塑料消费量与世界发达国家仍有较大差距。据统计,作为衡量一个国家塑料产业发展水平的塑钢比,中国仅为30:70,低于世界平均水平50:50,进一步低于发达国家如美国的70:30和德国的63:37。未来,随着我国改性塑料技术进步和消费升级,预计我国塑料产品需求将保持10%以上的增长速度。

  In terms of demand, there is still a big gap between China's per capita plastic consumption and the developed countries in the world. According to statistics, as a measure of a country's plastic industry development level, China's plastic-steel ratio is only 30:70, lower than the world average level of 50:50, further lower than developed countries such as the United States of America's 70:30 and Germany's 63:37. In the future, with the technological progress and consumption upgrading of modified plastics in China, the demand for plastics products in China is expected to maintain a growth rate of more than 10%.
  塑料制品应用广泛,庞大的下游产业为我国塑料制品产业的发展提供了强有力的支撑。随着《石化行业振兴细则》的出台,我国塑料制品行业迎来了新的发展机遇。我国塑料制品市场需求主要集中在农业塑料制品、包装塑料制品、建筑塑料制品、工业运输和工程塑料制品等方面。
  Plastic products are widely used, and the huge downstream industry provides strong support for the development of China's plastic products industry. With the promulgation of "Detailed Rules for the Revitalization of Petrochemical Industry", China's plastic products industry has ushered in new opportunities for development. The market demand of plastics products in China mainly concentrates on agricultural plastics products, packaging plastics products, building plastics products, industrial transportation and engineering plastics products.
  聚乙烯塑料(聚乙烯)是一种乙烯基单体聚合物。原料有石油、焦炉煤气或酒精。聚乙烯工业生产一般采用乙醇脱水、乙炔催化加氢或高温热解等方法。其商品名称称为“b塑料”;缩写是PE。由于聚乙烯的密度不同,分为低密度聚乙烯。[PE(L)]、中密度聚乙烯[PE(M)]、高密度聚乙烯[PE(H)]。
  Polyethylene plastics (PE) is a vinyl monomer polymer. The raw materials are petroleum, coke oven gas or alcohol. Ethanol dehydration, acetylene catalytic hydrogenation or high temperature pyrolysis are commonly used in polyethylene industry. Its commodity name is "b plastic"; abbreviation is PE. Due to the different density of polyethylene, it is divided into low density polyethylene. [PE(L)], medium density polyethylene [PE(M)], high density polyethylene [PE(H)].
  聚乙烯的分子结构公式为:(- CH2 - CH2 -) n。
  The molecular structure formula of polyethylene is (- CH2 - CH2 -) n.
