大尺寸、高强度、轻质、长寿化。随着煤炭工业的发展，一大批500万吨甚1000多万吨的大型矿井相继建成，对大型、高强度阻燃输送带的需求日益增加。超大型矿井需要宽度大于1600毫米甚大于3000毫米、强度大于2500牛顿/毫米甚4000牛顿/毫米的阻燃输送带，这种输送带承载能力大、输送距离长，因此要求强度高、使用寿命长。同时，要求皮带薄、重量轻、利节省投资、耗能，必须采用新的骨架材料来满足要求。
Large size, high strength, light weight and long life. With the development of coal industry, a large number of 5 million tons or even 10 million tons of large-scale mines have been built, the demand for large-scale, high-strength flame-retardant conveyor belt is increasing. Super large mines need flame retardant conveyor belt with width greater than 1600 mm or even more than 3000 mm and strength greater than 2500 n / mm or even 4000 n / mm. This kind of conveyor belt has large bearing capacity and long conveying distance, so it requires high strength and long service life. At the same time, it is required that the belt should be thin, light in weight, save investment and energy consumption, and new skeleton materials must be used to meet the requirements.
新材料和连续生产。阻燃输送带的强度主要取决于整个带芯的材料。目前，我国纬线、经线带芯整体以涤棉纱或锦纶/cotton纱为主，带厚、重、强度低。在国外，聚酯或芳纶纤维通常用作经线，而锦纶和棉纱在纬线，使用，因此它具有纤芯薄、重量轻和强度高的特点。随着高性能、薄层化、轻量化的发展趋势，强度在3000 N/mm以上的整个带芯应优先选用芳纶纤维作为经线，使带体轻薄，便于浸渍和塑化，大大提高输送带的强度，延长其使用寿命。
New materials and continuous production. The strength of flame retardant conveyor belt mainly depends on the material of the whole belt core. At present, the core of weft and warp in China is mainly polyester cotton yarn or nylon / cotton yarn, with low belt thickness, weight and strength. In foreign countries, polyester or aramid fiber is usually used as warp, while nylon and cotton yarn are used in weft, so it has the characteristics of thin core, light weight and high strength. With the development trend of high performance, thin layer and lightweight, aramid fiber should be preferred as warp for the whole belt core with strength above 3000 n / mm, so as to make the belt body light and thin, easy to impregnate and plasticize, greatly improve the strength of conveyor belt and prolong its service life
品种多样，应用广泛。目前，我国聚氯乙烯和PVG阻燃输送带主要用于煤矿。实际上，它可以应用于除高温物料以外的任何地方的物料运输。在国外，不仅有煤矿用阻燃输送带，还有煤矿和非煤矿行业用的通用阻燃输送带。然而，煤矿用阻燃输送带对阻燃性能有更严格的要求。
Various varieties and wide application. At present, PVC and PVG flame retardant conveyor belts are mainly used in coal mines. In fact, it can be used for material transportation anywhere except high temperature materials. In foreign countries, there are not only flame retardant conveyor belt for coal mine, but also general flame retardant conveyor belt for coal mine and non coal industry. However, flame retardant conveyor belt for coal mine has more stringent requirements on flame retardant performance.
、、。、、是输送带行业的发展趋势。聚氯乙烯和PVG阻燃输送带是、、的产品。高强度阻燃输送带使用寿命长，能充分利用资源效率。该热塑性弹性表面阻燃输送带生产工艺简单，能耗低，生产效率高，胶料可重复使用，是符合循环经济、、、的产品。低毒、低烟、阻燃输送带是一种更、更的产品。
Energy saving, safety and environmental protection. Energy saving, safety and environmental protection are the development trend of conveyor belt industry. PVC and PVG flame retardant conveyor belt are energy-saving, safe and environmental protection products. High strength flame retardant conveyor belt has long service life and can make full use of resource efficiency. The thermoplastic elastic surface flame-retardant conveyor belt has the advantages of simple production process, low energy consumption, high production efficiency and reusable rubber material, which is in line with circular economy, energy saving, safety and environmental protection. Low toxic, low smoke, flame retardant conveyor belt is a safer and more environmentally friendly product.
人才、技术、市场和效益集中在少数企业。目前，有80多家聚氯乙烯和PVG阻燃输送带生产企业，其中大部分是小企业，有十多家大中型胶带企业，而国外生产类似产品的企业只有十多家，其中大部分是大企业和世界知名。近年来，阻燃输送带的国内市场和效益逐渐集中在外资企业和大中型企业。随着外商投资企业进入和国内胶带行业开展质量信用活动和实施战略，市场和效益越来越集中在少数强势企业，同时人才、资金和技术也逐渐转移到少数强势企业。
Talent, technology, market and benefits are concentrated in a few enterprises. At present, there are more than 80 PVC and PVG flame-retardant conveyor belt manufacturers in China, most of which are small enterprises, more than 10 large and medium-sized belt enterprises, while there are only more than 10 foreign enterprises producing similar products, most of which are large enterprises and world-famous brands. In recent years, the domestic market and benefits of flame retardant conveyor belt are gradually concentrated in foreign-funded enterprises and large and medium-sized enterprises. With the entry of foreign-invested enterprises and the implementation of quality credit activities and famous brand strategy in domestic tape industry, the market and benefit are more and more concentrated in a few strong enterprises, while talents, capital and technology are gradually transferred to a few strong enterprises.
