Description
Alkaline phenolic resin &hardener process, also known as a-set process,the appearance of the resin is brownish red liquid, with the following characteristics:
1. Resin does not contain N, curing agent does not contain S, P, to avoid the casting surface produced by the increase of P S,tissue deterioration, nitrogen gas holes and other defects.
2. Good applicability of the original sand.Alkaline phenolic resin applies not only to acid consumption value low quartz sand, zircon sand, South Africa Ge iron ore, is also applicable to the sand with higher acid consumption values, chromite sand and magnesium olivine sand.
3. Good applicability of the original sand.Alkaline phenolic resin applies not only to acid consumption value low quartz sand, zircon sand, South Africa Ge iron ore, is also applicable to were the sand with higher acid consumption values, chromite sand and magnesium olivine sand.
4. Free formaldehyde content is low,only 0.2%,the use of the curing agent has no peculiar smell, labor hygiene condition is good.
5. Alkaline phenolic resin&hardener sand are with low gas evolution and good collapsibility, so it can reduce cleaning time and improve work efficiency.
6.The curing performance is good, the molding time can be adjusted, with three types of curing agent, can meet the different seasons of a year on the type (core) sand curing.
7.In Al-Cu alloy castings, casting porosity is reduced; improved air tightness and core collapsibility is good, high dimension accuracy of castings, make the finished product rate is greatly increased.
