目前我国制革化工材料在产品结构、生产效率、研究开发等方面与国外相比有较大差距。主要表现在: ——产品老、质量低、配套差。目前生产的皮革化工产品中,有40%以上的品种是10年前的产品,而且这些产品的产量占全部皮革化工产品产量的一半以上,产品质量多属中低档,少数产品性能接近国外80年代后期水平,有些产品仍存在质量问题。产品的配套性也比较差,如丙烯 At present, there is a big gap between China’s leather chemical materials in terms of product structure, production efficiency, and research and development compared with foreign countries. Mainly in: - Old products, low quality, poor matching. More than 40% of the current leather chemical products are produced 10 years ago, and the output of these products accounts for more than half of the total output of leather chemical products. The product quality is mostly in the middle and low grades, and a small number of product properties are close to foreign 80s. At the later stage, some products still have quality problems. The compatibility of the product is also relatively poor, such as propylene
