Configuration and mechanism of windshield glass laminated with standard PVB film were briefly described and a new type improved windshield glass with enhanced sound-proof performances developed by Shou-Fu-Xin Inco.
简要介绍了标准PVB中间膜挡风玻璃的结构和原理,重点介绍了一种首孚信TM公司新开发的增强型隔音PVB中间膜挡风玻璃,分析、比较了两种挡风玻璃的声传递特性。
2)  sound-proof PVB film
隔音PVB中间膜
3)  PVB filem
PVB 膜
4)  PVB film
PVB薄膜
1.
The thermal and photo aging mechanism of PVB film was studied by the use of IR spectra and the change of tensile strength.
利用红外光谱和力学性能的变化研究了聚乙烯醇缩丁醛薄膜的热老化和紫外光老化机理,结果表明,在热老化及紫外光老化过程中,PVB薄膜的拉伸强度均是先增大然后再减小。
2.
Effect of chain extenders on PVB resin and film was studied The addition of chain extender in synthesis of PVB resin was 3% of the volume of butyl aldehyde and in processing of the film no more than 3% of the quality of PVB resin, thus the Mw of PVB resin was increased, adhesion of PVB film to glass decreased, and tensile strength of PVB film raised greatly.
实验证明,合成树脂时加入相对于正丁醛体积3%左右的扩链剂1;加工成膜时,加入相对于PVB树脂质量3%以下的扩链剂2,可明显提高PVB的分子量,降低PVB薄膜与玻璃的粘结性能,所得薄膜的拉伸强度可明显提高,而且制得的夹层安全玻璃的耐冲击性能没有受到影响。
5)  PVB Film
PVB膜片
1.
Common Problem and Improving Method of Laminated Safety-glass with PVB Film as Interlayer;
使用PVB膜片作为安全玻璃夹层的常见问题与改进方法
6)  CA-PVB blend membrane
CA/PVB共混膜
补充资料:隔音
分子式:
CAS号:

性质:又称隔声。用隔声材料或结构降低声的传输的过程。隔声是以隔声量来评价。测试时分别在声源室及接收室内测出平均声压级,再根据试样面积与接收室等效吸收面积计算出隔声量R:式中L1为声源室平均声压;L2:接收室平均声压;S为试样面积,m2;A为接收室等效面积,m2;,V为接收室体积,m3;T为接收室混响时间,s。工程上常采用重质密实材料(如钢板、混凝土、玻璃等)或铺设吸声材料隔声,或采用中间为空气层的双层、多层结构改善隔声性能。
