本刊讯上海克络蒂材料科技发展有限公司日前成功研发的聚氨酯复合材料门窗,成为2014年8月住房城乡建设部新版《建筑设计防火规范》发布后,首批通过耐火完整性测试的节能门窗。产品的型材为玻璃纤维增强聚氨酯复合材料,以无纺玻璃纤维纱为增强相,聚氨酯树脂为基体树脂,通过拉挤工艺成型。据介绍,聚氨酯复合材料加工过程中尺寸收缩率小于0.2%,与设计尺寸偏差小,具有良好的尺寸稳定性。此外,其线膨胀系数大大低于铝合金和PVC塑
The news of Shanghai Geluo Di Material Science and Technology Development Co., Ltd. recently successfully developed polyurethane composite doors and windows, became August 2014 Housing and Urban Construction Ministry of new version of “architectural design code for fire protection” after the release of the first batch of fire-proof integrity testing of energy-saving windows and doors . The profile of the product is glass fiber reinforced polyurethane composite material, with the non-woven glass fiber yarn as the reinforcing phase and the polyurethane resin as the matrix resin, which are shaped by the pultrusion process. According to reports, polyurethane composite materials processing shrinkage rate of less than 0.2%, with the design of small deviations, with good dimensional stability. In addition, its linear expansion coefficient is much lower than aluminum alloy and PVC plastic
