影响玻璃钢雕塑质保期的三大因素

发布日期: 2020-08-20 来源:http://www.mmyljg.com 点击: 发布人:mianmao

我们所看到的玻璃钢雕塑内部都是有玻璃纤维、树脂、界面所组成,所以在这三方面一定要在质量与制作上非常精良,才能够延长玻璃钢雕塑质保期,当然漆面也非常重要。

All the FRP sculptures we see are composed of glass fiber, resin and interface. Therefore, the quality and production of these three aspects must be very excellent in order to extend the warranty period of FRP sculptures. Of course, the paint surface is also very important.
(一) 玻璃纤维对玻璃钢雕塑质保期影响
(1) Effect of glass fiber on the quality assurance period of FRP sculpture
玻璃纤维是玻璃钢中的主要承力部分,它不仅能够提高玻璃钢的强度和弹性模量,而且能够减少收缩变形,提高热变形温度和低温冲击强度等.列如306#聚酯树脂浇铸体,在加入50%的玻璃布后.拉伸强度可由50MPa提高到200MPa,拉伸模量可由3.9GPa提高到14GPa.
Glass fiber is the main load-bearing part of FRP. It can not only improve the strength and elastic modulus of FRP, but also reduce the shrinkage deformation, improve the thermal deformation temperature and low-temperature impact strength. For example, the tensile strength of 306 ා polyester resin casting body can be increased from 50MPa to 200MPa and the tensile modulus can be increased from 3.9gpa to 14gpa after adding 50% glass cloth
(二)合成树脂对玻璃钢雕塑质保期影响
(2) Effect of synthetic resin on the quality assurance period of FRP sculpture
合成树脂是玻璃钢的基体,松散的玻璃纤维靠它粘接成整体。合成树脂的好坏直接影响玻璃钢雕塑质保期限。
Synthetic resin is the matrix of glass fiber reinforced plastics. Loose glass fiber is bonded into a whole by it. The quality of synthetic resin directly affects the warranty period of FRP sculpture.
树脂主要起传递应力作用,因此树脂对玻璃钢的强度起重要作用,尤其是抗压、弯曲、扭转、剪切强度更为显著。
Resin is mainly used to transfer stress, so resin plays an important role in the strength of FRP, especially the compressive strength, bending strength, torsion strength and shear strength.
由于树脂是基体材料,它对玻璃钢的弹性模量、耐热性、电绝缘性、头电磁波性、耐化学腐蚀性、耐气候性、耐老化性等都有影响。
Because resin is the matrix material, it has influence on the elastic modulus, heat resistance, electrical insulation, electromagnetic wave property, chemical corrosion resistance, weather resistance and aging resistance of FRP.
列如玻璃钢的耐化学液体侵蚀性和耐水性,主要取决于树脂基体的性能。通常不饱和聚酯树脂197#耐化学腐蚀较好,而1289#耐水较好。不同类型、不同牌号树脂其性能是不相同的。
For example, the chemical resistance and water resistance of FRP mainly depend on the properties of resin matrix. Generally, unsaturated polyester resin 197 ා has better chemical corrosion resistance, while 1289 ා has better water resistance. The properties of different types and brands of resins are different.
树脂含量对玻璃钢性能也有影响,通常树脂含量为20%-35%,这和成型方法、曾强材料品种有关。列如,缠绕和模压成型,树脂含量偏低,而手糊成型、树脂含量则稍高。强度层树脂含量稍低,通常可在25%-40%之间;耐腐蚀、防渗层树脂含量较高一般要超过50%用玻璃布作增强材料,树脂含量低于用玻璃毡。
The resin content also has an effect on the properties of FRP, which is usually 20% - 35%, which is related to the molding method and the variety of Zeng Qiang materials. For example, winding and molding, resin content is low, and hand paste molding, resin content is slightly higher. The resin content in the strength layer is slightly lower, usually between 25% and 40%; the resin content in the anti-corrosion and anti-seepage layer is higher, generally more than 50%. Glass cloth is used as reinforcement material, and the resin content is lower than that of glass mat.
用玻璃纤维表面毡作增强材料时。可达85%以上的富树脂含量。
When glass fiber surface mat is used as reinforcement material. The resin rich content can reach more than 85%.
(三)界面对玻璃钢雕塑质保期影响
(3) Influence of interface on the quality assurance period of FRP sculpture
所谓界面就是任何两相物质间的分界面。
Any interface between two phases is called an interface.
玻璃钢雕塑质保期的性能不仅与所用的增强材料、合成树脂有关,同时,很大程度上还和纤维与树脂之间界面粘合的好坏及耐久性有关。
The performance of FRP sculpture warranty period is not only related to the reinforcement materials and synthetic resin, but also to a large extent to the interface bonding between fiber and resin and durability.
