The process recipe and parameter control in indigo dyeing ground and pigment discharge printing were introduced,that is reduction 40~50 min at atmospheric temperature,pH value 10~12,85 % sodium hydrosulfite 6 g/L,discharge agent BT-100,fixation 150 ℃×40 s.
介绍了靛蓝染底和涂料拔染印花工艺处方、参数控制,即常温下还原40~50 m in,pH值在10~12,85%保险粉6 g/L,拔染剂选择BT-100,固色150℃×40 s;
As a result,adding suitable dosage of sodium bicarbonate,urea 10 g/L,CMC 2.5 ~ 3.0 %,ammonia sulfate > 2.0 % during pretreatment,and printing ink preparation with suitable reactive dye and higher concentration of humectants,controlling pH value between 5.5 to 6.5,can meet the requirement of fixation rate to military textiles.
Application of CITYgreen model in benefit assessment of Nanjing urban green space in carbon fixation and runoff reduction
The results indicate that carbon fixation benefits received by the main city of Nanjing is 5%-60% of that by natural forests on a per unit area basis.
The ecological value of carbon fixation and runoff reduction of the Nanjing urban green space was about 177 million RMB in total.
The bacteria can assimilate oil hydrocarbons as the sole source of carbon and energy, both in the presence of fixed nitrogen and during nitrogen fixation.
The most active enzyme fixation was observed in the case of a late (after 14 days) application of nitrates in the variants with both separate inoculations and inoculation with the binary preparation of A.
