Casting molding with furan resin, curing agents, adhesives, release agents, etc.

Texas Mae Ping Casting Material Co., environmentally friendly high-strength furan resin has the following advantages: fast curing, high strength, environmentally friendly resin can reduce the amount of 10% to 20%, the production cost of the casting dramatically reduced. Formaldehyde resin content is very low, greatly reducing the environmental pollution, improved working conditions for workers. Reduce the amount of resin type will reduce the core gas evolution, will help reduce or eliminate such defects casting porosity; the curing speed, curing agent is added in an amount corresponding to reduce, reduce the casting surface by S, the ball bad defects. 1. The amount of resin sand process is generally 0.7-1.5% (total sand weight), the curing agent is generally added in an amount of 30-60% (total resin weight), with a continuous or batch mixer first sand and curing agent mix, and then added to the resin mix, sand time is usually 5 to 60 seconds, immediately after use sand mix. 2. The amount of the resin As a result of the use of choice used by manufacturers of original sand shape, size, clay and other indicators vary greatly, different type, weight and complexity of the core, the amount of resin should be added in order to meet production needs for the principle, minimize the amount of resin in the strength to meet the production requirements of the premise. 3. Control controls the release time of the release of the appropriate time (typically 10-40 minutes), releasing prematurely will produce even worse type stick mold, core or fallen container; releasing too late then stripping difficulties and even damage type , core or model. The cure rate to control the curing speed is too slow, and appropriately increase the amount of curing agent is added (generally not more than 70%) or replace the curing faster curing agent; curing too fast, appropriate to reduce the curing agent is added in an amount (generally not low 30%) or replace slower curing hardener. Note 1. Non resin and hardener are mixed directly prevent an explosion! 2. When the resin in contact with the skin, may cause the body to produce a slight stimulation of individual operator should wear protective gloves and other supplies. 3. The resin should be stored airtight in a cool, dry place, away from heat or sunlight, handling should be handled with care. Packaging 240 kg drum
