国内纯苯市场近期表面保持安静,主要是受生产厂家出厂价格稳定的支撑。华东、华南地区纯苯报价在10250-10550元/吨,国内纯苯生产厂家中,扬子石化、上海石化、长岭炼化、茂名石化、镇海炼化、锦州石化、九江石化等主要厂家出厂报价仍然稳定在10500元/吨一带,齐鲁石化、大庆石化等厂家出厂报价稳定在10200—10300元/吨。西北地区纯苯厂家的出厂报价稳定在9500元/吨左右。 相似文献

The purpose of this study was to investigate the bleaching efficiency of activated sodium perborate at low washing temperatures and the resulting energy saving. The comparison of the washing efficiency of basic and activated detergent was based on practical washing tests. The types of dirt used were coffee, fruit juice, tea, blood and a soot-oil mixture. The washing temperatures were 50, 60, 70 and 80°C. The cleanness of the washing was determined by a whiteness measurement. The consumption of electrical energy was measured with a kWh-meter. The higher the temperature, the more effectively all the types of dirt were removed from the textiles. With activated detergent a cleanness was obtained at 50°C and 60°C that was almost as good as with basic detergent at 80°C. The coloured types of dirt washed out more easily than blood or the soot and oil mixture. An average saving of 20% in the consumption of energy was obtained when the washing temperature was lowered by 10°C. With activated detergent, 45% of the energy consumed using basic detergent was saved with no reduction in the final cleanness. 相似文献

The purpose of the study was to investigate the effect of fibre content and method of application of selected interfacing fabrics on appearance of garments after repeated laundering. Experimental fabrics were three interfacings of 100% polyester sew-in, 100% rayon and 100% polyester fusible, and two white fashion fabrics of polyester/cotton durable press treated and 100% cotton. Thirty blouses were constructed and divided into six groups representing six combinations of fashion and interfacing fabrics. Evaluation methods included appearance, dimensional stability and stiffness. Data were statistically analysed using t tests and Pearson rank order correlation coefficient. Results showed that method of applying interfacing fabrics had a significant effect on appearance of the combined fashion and interfacing fabrics. Sew-in method resulted in satisfactory appearance throughout repeated laundering for polyester/cotton DP fabric. Deterioration of adhesive resin of fusible interfacings in the laundering process resulted in significant shrinkage and poor appearance. Also, relationship was found between per cent shrinkage and appearance ratings indicating that as per cent shrinkage increased, appearance ratings decreased. Effect of fibre content of interfacings on appearance was not significant. However, interfacing fabrics were found to be the major contributor to shrinkage of composite fabric and not the fashion fabrics. Poor appearance of fusible interfacings was related also to per cent loss of stiffness. 相似文献
