Anyproductis difficult to function properly if not used correctly.Therefore, usingPUR hot melt glue machines also requires choosing the correct methods to ensure the equipment's effectiveness and guarantee glue stability, avoidingpipeline blockage. Below, we will share how to correctly use PUR hot melt glue machines.The PUR hot melt glue machine
is very different from ordinary EVAhot melt glue machines.PUR hot melt gluemainly consists of end isocyanate polyurethane prepolymer.It should not be in contact with air for long periods; otherwise, it will undergochemicalreactions and solidify, causing blockage in the entire delivery pipeline of the hot melt glue machine..Therefore, the glue in a PUR hot melt glue machine is sealed off from air.。所以PUR热熔胶机的胶是密封的与空气隔绝的。同时在使用PUR热熔胶机时如果发现热熔胶机设备上的密封有损坏，要及时更换密封件，防止PUR热熔胶机与空气接触固化后无法清除，另外在使用PUR热熔胶机设备过程中，如果热熔胶机上沾有热熔胶也要及时擦拭干净。最后PUR热熔胶机设备在停机后，同样也是要把各个出胶口密封好，或者将机器内的胶排干净，避免长时间与空气接触发生化学反应从而固化造成热熔胶机管道堵塞。
PUR热熔胶机现被广泛应用于包装、木材加工、汽车、纺织、机电、航空航天等国民经济领域。PUR热熔胶粘剂是分子结构中含有极性和化学活泼性的氨酯基（-NHCOO-）或异氰酸酯基（-NCO），与含有活泼氢的材料，如木材、皮革、织物、纸张、陶瓷等多孔材料和塑料、金属、玻璃、橡胶等表面光洁材料都有着优良的粘合力。
PUR热熔胶机是另一种高技术的热熔胶机设备，对热熔胶机生产厂家有更高的要求。精泰热熔胶机厂家为了满足市场的需求，自主研发了多款PUR热熔胶机，性能稳定，适合要求比较高的行业。
