METAL TREATMENTS |
| 配方组成： |
molybdeum powder (particle size 2-10 μ)/80.0
"carbopol" 934/1.0
sodium hydroxide (10% sol'n)/4.2
water/20.0 |
| 配制方法： |
carefully disperse the "carbopol" 934 resin in the water and then neutralize with the sodium hydroxide. add the metal and stir to uniformity.
note: at such a high metal content, the suspension is a stiff paste.
no water separaters on aging.
for a more fluid suspension it is advisable to reduce the metal content to about 60% total solids. lower concentrations of "carbopol" 943 or 941 resin would then be possible, giving lower viscosities. or "carbopol" 941 resin can be used for highly stable suspensions, but at lower viscosities. |
