Yellow dextrin is widely used in abrasive abrasives, sand casting, refractory materials and rubber products, especially in abrasive abrasives and refractory materials, refractory materials, lightweight bricks, shaped bricks, etc. Good effect, according to the proper ratio, blending, stirring evenly, in the shape, it has an excellent effect on preventing collapse and maintaining the angle.
1. Grinding wheel industry, ceramic grinding wheel must use auxiliary materials.
2, dextrin in the small and medium-sized foundry industry (except large-scale resin sand type) oil sand core type in the production of aleurone plus fat oil (Tonghu better) made of oil sand core type is stronger than clay sand several times .
3, casting bond powder, can be directly mixed with foundry sand (add appropriate amount of water, no fat oil) to make the core type comparable to oil sands.
4, dextrin can also be used as an adhesive for wood-based panel special tape paper.
5, dextrin used in the chemical industry for several export dyes as additives
