软木粉

软木粉脱模剂溶液易于变质或发酵。

Cork mold spray solutions have a tendency to deteriorate or ferment .

制备脱模剂的关键似乎在于稀的硅酸钠溶液与软木粉的颗粒彻底混合。

The secret of preparing mold spray seems to lie in the thorough incorporation of the dilute silicate solution in the granules of cork .

硅酸钠能使软木粉粘结在模具表面，而且还有助于软木粉耐受熔融铅合金的碳化作用。

The sodium silicate makes the cork stick to the mold surface and also helps to withstand the charring action of the molten lead alloy .

用短绒、粉末、软木粉或类似品部分覆面并由此而形成图案的织物，但仿绒织物仍归入本品目；
