China rubber belt industries and development prospects
1 production capacity and output in China is the tape, the production and consumption of a certain scale of production enterprise on tape. A rough estimate of the 2004 national tape, rubber products, consumption amount (including resin) about 100,000 t, about the amount of tape consumption 1/3, the rubber consumption amount of 2.5%. According to statistics, at present the roughly industry belt of the annual production capacity of about 2.5 million m2, with annual production capacity of 10 million above the top of the world, rw. According to concerning sectional statistic, 2001-2004 in the production of conveyor belt 7246 respectively, 7327.52, 8876.21, 10,000 thousand m2, the yield of V belt 63700 respectively, 65410.45, 76341.2, 88000 million. According to estimation, the 2004 national adhesive products of GDP in about 60 million yuan, accounts for about 4% of GDP rubber products. According to the customs statistics, 2001-2004 national adhesive products export value 6256, respectively 8635, 63, 12720 million us dollars, import, 62, 6011 respectively 10415, 11916 million dollars. In 2004, our product export value of tape than in 2003, but still have increased with imported flat. In general, our products is more than the self adhesive tape, nylon conveyor belt, our products are raised edge conveyor belt around the country. And some export, overcapacity, Instead, due to the varieties, specifications and quality of water and other factors, each part to import.
2 our tape industry development characteristics of enterprise wide distribution, quantity, but also more concentrated. Almost all the various provinces and autonomous regions have tape, and has manufacturing enterprise size enterprises hundred, But the main focus on tape enterprise, zhejiang, shandong, hebei, henan, jiangsu, Shanghai, guangdong and liaoning province. In addition, China top 10 tape industry production of the national total 60% of the tape. For example, according to statistics, China rubber industry association as zhejiang province in 2004 with production, about 450 million Am mother-town of protocols were 51.1%, Belt output reached 1406 million m2, about mother-town of 14%, Tape from 288 billion yuan to export value, the value of exports of tape 1/4. The tape again and zhejiang industrial concentration in ningbo, shaoxing, tongxiang, gates, tiantai etc. And as China rubber industry association, according to statistics, shandong province in 2004 over the scale enterprise belt output reach 29.4 million m2, accounts for about 30% of the total conveyor belt. According to investigation, both clubs to the belt in hebei province, mainly concentrated in LiXian wild, production capacity of about 50 million m2, the annual output reaches 3000 million m2.
3 product quality status over the past 20 years, China's rapid development, tape, or whether belt transmission, and relatively complete varieties with international standards. In the level of product quality and timely pay more attention to adopting international standard and advanced foreign standards. Far more than 30 national standards or industrial standards of products. The national or trade standards

are basically with reference to the international standards or foreign advanced standards. At present, our country in synthetic fiber and wire core for the conveyer belt conveyor skeleton about 80 percent of the total, Strings of V belt structure already close to 80% of the total V belt, close to the international advanced level. Since 2003, the state of flame retardant belt and automobile V take two products implement the production license system in China, the tape to raise the level of product quality and a boost. Flame retardant conveyor includes coal mines with fabric core conveyer type and flame retardant PVC PVG type), flame retardant wire rope is used in coal mine belt conveyor and general purpose, four types of flame resistant conveyor belts, in addition to its yield, etc, annular belt conveyor about 1/3 of the total. Due to the flame retardant belt requirement and conducting electrostatic, and used for national key control in flammable and explosive place, its product is relatively high technical content, the product quality level in certain extent can represent our product quality level. Belt Auto V belt including bag type car V belt and trimming car with two types, automobile V belt use due to severe conditions are V belt products of high technology content, its quality products at some extent can also represent our V belt product quality status.

我国橡胶输送带行业的现状及发展前景
1.生产能力及产量 我国是世界胶带生产及消费大国，全国具有一定规模的胶带生产企业上百家。粗略估计，2004年全国胶带产品年耗胶量（包括树脂）约10万t，约占世界胶带耗胶量的1／3，约占全国橡胶制品耗胶量的2．5％左右。据行业粗略统计，目前全国输送带的年生产能力约2．5亿m2，V带年生产能力10亿Am以上，名列世界前列。据有关部门的统计数据，2001~2004年全国输送带的产量分别为7246、7327．52、8876．21、10000万m2，V带的产量分别为63700、65410．45、76341．2、88000万Am。据估算，2004年全国胶带产品的生产总值约60亿元，约占全国橡胶制品总值的4％左右。 据海关统计，2001~2004年全国胶带产品的出口交货值分别为6300、6256、8635、12720万美元，进口分别为6011、6200、10415、11916万美元。可以看出，2004年我国胶带产品出口交货值比2003年有较大增长，但仍与进口基本持平。总的看来，我国胶带产品是自给自余，我厂生产的尼龙输送带、挡边输送带远销全国各地。并有部分出口，生产能力过剩；相反，由于品种规格和质量水 平，以及其它因素所致，每年均需部分进口。
2.地区发展特点 我国胶带行业企业分布广、数量多，但相对又比较集中。全国各省市自治区几乎都有胶带生产企业，并有大小企业数百家；但胶带企业主要还是集中在浙江、山东、河北、河南、上海、江苏、辽宁、广东等省市。此外，我国胶带行业排名前10家的生产量约占全国胶带总产量的60％以上。例如，据浙江省橡胶工业协会统计，2004年全省V带产量达4．5亿Am，约占全国总产量的51．1％；输送带产量达1406万m2，约占全国总产量的14％；胶带出口交货值达到2．88亿元，约占全国胶带出口交货值的1／4。而浙江省的胶带工业又集中在宁波、绍兴、桐乡、三门、天台等地区。又如，据山东省橡胶工业协会统计，2004年全省规模以上企业输送带产量达到2940万m2，约占全国输送带总产量30％。再据管带分会调查，河北省的输送带主要集中在蠡县、博野一带，生产能力约5000万m2，年产量达3000万m2。
3.产品质量现状 近20年来，我国胶带产品发展很快，无论是输送带，还是传动带品种都比较齐全，并与国际接轨。在产品质量水平上，比较注意及时采用国际标准和国外先进标准。目前已有30余个产品国家标准或行业标准。这些国家或行业标准基本上都是参照国际标准或国外先进标准制定的。 目前，我国以合成纤维和钢丝绳芯作骨架的输送带约占输送带总量的80％；线绳结构的V带已接近V带总量的80％，接近国际先进水平。2003年起，国家又对阻燃输送带和汽车V带两类产品实施了生产许可证制度，这对我国胶带产品质量水平的提高又是一个极大的促进。阻燃输送带包括煤矿井下用织物芯阻燃输送带（PVC型和PVG型）、煤矿用钢丝绳芯阻燃输送带和一般用途阻燃输送带四种类型，另外还有耐热输送带、环形输送带等等，其产量约占输送带总产量的1／3左右。由于阻燃输送带要求阻燃和导静电，又用于国家重点控制的易燃易爆场所，其产品的技术含量相对较高，该产品的质量水平在某种程度上可以代表我国输送带产品的质量水平。汽车V带包括包边式汽车V带和切边式汽车V带两种类型，汽车V带由于使用条件相对严苛也是V带产品中技术含量较高的产品，它的质量状况在某种程度上也可以代表我国V带产品的质量状况。
