| 配制方法： |
Impregnate cotton flannel with above.
The solvents and water are mixed at 80F to 100F. The AEROSOL OT-75% is added slowly with continued mixing. After the AEROSOL OT has dissolved, all solutions will remain clear and liquid at temperatures as low as 50f. No scumming of the surface occurs because of evaporation during a normal run of the cloth through the bath. The solutions that are allowed to stand should be covered to prevent loss of solvent.
The optimum amount of AEROSOL OT to be left on the cloth is 40-50%, based on the weight of the cloth. However, a range of 25-50% will give satisfactory results. |
