Alkali Phenolic Resin Special Metering Pump

special stainless steel metering pump for resin sand mixer the advantage as follow;

1. Austenitic stainless steel 304, 304L, 316/316L and No. 20 alloy are used for the flow-through parts. After strict solid-melting treatment, the material crystal lattice and chemical composition are uniform, and the intergranular stress is small.

2. Gear metering pump can transport furan resin, alkali phenolic resin, curing agent, water glass curing agent, Piper resin I, resin II and catalyst.

3. Suitable for resin sand mixer with an output of 3-100 tons/hour.

Alkaline Phenolic Process

Alkaline phenolic resin does not contain nitrogen, sulfur, and phosphorus elements. It has a "second hardening phenomenon" at high temperatures, has a smaller cracking tendency than furan resin sand, does not emit irritating odors, has a good production environment, and has good falling sand cleaning performance. In recent years Applications in my country are gradually increasing. Alkali phenolic process generally adds 1.1-2.0% resin (accounting for sand weight), curing agent 20-30% (accounting for resin weight); fast and slow fat-alkali phenolic process generally adds 1.5-3.0% resin, and fast fat adds 0.1~0.3% (accounting for the weight of sand), and the amount of slow grease added is 0.2~0.5% (accounting for the weight of sand). First, mix the sand with the curing agent, and then add the resin. The sand mixing time is generally 5 to 60 seconds. Due to the high viscosity of alkali phenolic resin, the viscosity is sensitive to temperature changes, and it is very corrosive to rubber. Therefore, the pumps used for pumping alkali phenolic resin and curing agent at home or abroad are almost all gear metering pumps.

In the fast and slow fat-alkali phenolic process, the C series stainless steel pump is used to pump the alkali phenolic resin, and the selection is shown in the following table :
