阅读说明：本技术 废弃硬质泡沫喷水粉碎工艺 (Waste hard foam water-spraying crushing process ) 是由 齐凤君 范喜林 于 2020-12-17 设计创作，主要内容包括：本发明涉及到废弃聚氨脂泡沫喷水粉碎技术,由于聚氨脂硬质保温泡沫属轻体,干燥并带有静电属易燃物,在粉碎过程中极易造成燃烧、爆炸物料飞扬现象,喷水粉碎工艺能有效降低物料燃烧、爆炸飞扬等现象的发生,以确保人身财产的安全。(The invention relates to a water-spraying crushing technology for waste polyurethane foam, wherein the polyurethane rigid heat-insulating foam is light and dry and is provided with static electricity which is inflammable, so that the phenomena of burning and explosion of materials are easily caused in the crushing process, and the water-spraying crushing technology can effectively reduce the phenomena of burning, explosion, flying and the like of the materials so as to ensure the safety of human bodies and properties.)

1. Because the polyurethane rigid heat-insulating foam is light, dry and electrostatic, and belongs to inflammable materials, the materials are soaked in water and wet during crushing, and water is sprayed into the crusher to improve the wettability of the materials and reduce the risks of material combustion and explosion flying.

2. The process of claim 1 wherein the rigid foam is water-jet milled by: the material is always in a wet state in the crushing process, and the particle size of the crushed material is basically consistent.

3. The process of claim 1, wherein the water jet milling of the rigid foam is carried out by: the secondarily crushed material is packaged in a semi-dry powdery filling bag for later use.
