聚氨酯（简称pu)门内填充发泡技术是最新的技术，广泛应用在目前制门行业中。
其操作简单，经济实用，只需要一台聚氨酯高压发泡机和一台门压机就可以生产，对门板内部进行填充发泡，代替过去的蜂窝纸，绝缘纸等等。
门板内部发泡成型后为硬质泡沫结构，完全由设备打料发泡完成。其原料成本低，性价比高，制作出来的门板具有抗冲击压力，阻燃性强，防虫蛀防腐蚀，保温性好，隔音效果强等特点。（随时欢迎来我厂参观考察，现场演示操作过程，并让客户亲自质量检查）
我厂除了提供生产设备以外，还提供全套相应的原料及配方，（原料中加入了阻燃剂，可以有效阻燃，完全符合国际标准）我们将全力配合门业生产需要，为门业开辟一条崭新的道路。
请感兴趣的老板与我们联系，共同合作努力，抢占这片商机，不要再让消费者为门业抱怨，为填充纸发愁，给客户做最优质合格的好门。
Polyurethane (referred to as pu) door filled with foam technology is the latest technology, widely used in the current system the door industry.
Its operation is simple, economical, only need a high-pressure polyurethane foam machine and a press can produce the door, filled with foam on the inside door panel to replace the past honeycomb paper, insulation paper and so on.
Door after the internal foam molding rigid foam structure, fully completed by the device to play foam material.The low cost of raw materials, cost-effective, production out of the door with shock pressure, flame and strong, anti-insect anti-corrosion, good insulation, sound insulation, and other characteristics.(Always welcome to visit our factory inspection, a live demonstration of operation, and allow customers to personally quality check)
I plant in addition to providing production equipment, it also offers a full range of raw materials and the corresponding formula (raw materials added flame retardant, can be effectively fire retardant, full compliance with international standards) we will fully cooperate with the production of door needs to open up a doornew road.
Interest owner, please contact us and work together to seize this opportunity, do not let the door complaining consumers, the filled paper to worry about, to the customer the best qualified to do a good door.
