Product Description

The hot core box resin is a kind of adhesive cured under heating conditions. The curing process is divided into two stages. The first stage is: the curing agent releases strong acid under heating conditions; the second stage is: Under the catalysis of strong acid, the resin quickly solidifies. The binder system consists of two components, component I is furfuryl alcohol modified urea-formaldehyde resin and component II is curing agent, which is suitable for high-efficiency core making of non-ferrous metals, cast iron and cast steel.

Product features:

◎ High strength, low resin addition, can reduce production costs

◎ Fast resin curing, high production efficiency and energy saving

◎ Low viscosity, easy sand mixing, good fluidity of core sand

◎ Good moisture resistance, long storage time of sand core

◎ Good collapse

Specifications:

Usage:

1. Resin and curing agent addition ratio: 2.0-3.5% (accounting for sand weight) and curing agent 15%-30% (accounting for resin weight);

2. The sand mixing process uses an intermittent sand mixing machine to mix sand and curing agent for 1 minute, then add resin for 2 minutes, and then produce sand and core after mixing;

3. Curing temperature and time selection

curing temperature: 200-250 ℃, curing time: 10-120s, the thicker the sand core, the longer the curing time;

the curing temperature is high, the curing speed is fast, the curing temperature is too low or the time is too short, which will cause incomplete curing of the sand core. If the curing temperature is too high, the risk of sand core deformation and surface overburning will increase. If the curing time is too long, it will cause overcuring and demoulding difficulty.

Specifications and packaging: resin: 25kg/barrel, 240kg/barrel, curing agent: 25kg, 240kg.

Precautions

1. The resin is toxic and irritating, and the curing agent is corrosive and irritating to eyes and skin. Appropriate protective clothing, gloves and goggles/masks should be worn and used in a well-ventilated place;

2. Resin and curing agent are flammable, resin and curing agent and other acid substances can be directly mixed to produce explosion, the use of explosion-proof ventilation system and equipment, the site should be equipped with fire fighting equipment and emergency treatment equipment;

3. Once the eyes are in contact, lift the eyelids, immediately use a large amount of flowing water or normal saline to wash continuously for 15 minutes and then seek medical treatment;

4. Handle with care during handling and loading and unloading;

5. This product should be stored in a dry and ventilated place below 25 ℃ to avoid rain and sun and away from heat sources;

6. Empty containers are strictly prohibited from cutting and heating without thorough cleaning.
