In order to examine the effect of nitrilon fibre dust on health of operating workers, labour hygienics investigation was carried out in woollen sliver shop of a nitrilon fibre mill. 为探讨腈纶粉尘对作业工人健康的影响,对某腈纶厂毛条车间进行了劳动卫生学调查。
Waste nitrilon fibre can be hydrolyzed catalytically in a autoclave the hydrolysate can be compounded to a new casting adhesive. 腈纶废料经高温、高压、催化水解后复配,可得到一种新型铸造粘结剂。
The process of ferrous ion removal was improved for the nitrilon plant by sodium rhodanate one-step method and the consumption of materials decreased. 根据这一理论对硫氰酸钠一步法腈纶装置的除铁工艺进行改进后,装置的物料消耗量显著减少。
Effect of short fiber content in blended nitrilon/ ar-amid system on properties of flexible insulation composite 腈纶/芳纶共混短纤维用量对柔性绝热层材料性能的影响
Study on Enhanced Treatment Nitrilon Chemical Industry Wastewater by Internal Electrolysis Process 内电解强化处理腈纶废水的试验研究
Because of the characteristic of the nitrilon wastewater, the effluent of actual treating processes is difficult to obtain wastewater discharge standard of two grade of china. The nitrilon wastewater made severe environment pollution and great environment press to discharge area. 由于腈纶废水的特殊性,使得现有的腈纶废水处理工艺都很难达到国家二级排放标准,给腈纶废水排放地区造成了严重的环境污染和很大的环境压力。
The domestication time of granule sludge was over 3 months for treating the nitrilon wastewater, because of the effect of CN-concentration. 处理腈纶废水的驯化时间达3个月,主要是由于废水中所含毒性物质(CN-)的影响。
Nitrilon wastewater is a kind of high COD, complicated composition, biochemical sex differences, contain toxic and harmful substances, and difficult to degradation of industrial waste water. 腈纶废水是一种高COD、成分复杂,可生化性差,含有有毒有害物质,并且难降解的工业废水。
