玻璃鋼出現損壞應該如何進行修補?下面泰佳成玻璃鋼為大家解釋一下玻璃鋼如何進行修補,給大家一些日常生活中的建議。


玻璃鋼修復時先將損壞的部件拆下來,若是鋼板制件先整型,除銹,清洗涼干。若是塑料的先用膠粘法或熱焊補法將其復原(不用考慮強度),然后清洗干凈涼干,就可進行修復加強工作了。


一,首先將玻璃纖維布按工件大致外形進行裁剪(應比工件稍大,然后除蠟(也可先除蠟后裁剪),業余條件下可采用烘烤法除臘。找一500-1000W電爐,通電紅熱后將玻璃布放上往烤不冒煙為止即可(單層烘烤,不要折疊)。


二,弄好玻璃布后就可配制膠液了,膠液的配方有很多種,業余條件下一般用環氧樹脂和聚胺樹脂按1:1進行配比。玻璃鋼這種配方的特點是配比要求不嚴格,固化時間長,較長的固化時間可獲得從容的操縱時間(有些配方固化時間只有30分鐘,會令初學者措手不及)配制方法:先將兩種樹脂按1:1的比例倒進一個闊口容器中,用棍子充分攪拌攪勻。攪拌時如感覺太稠可加點天那水或丙酮進行稀釋。稠度一般以提起棍子不拉絲為好。(一定要攪拌均勻,另外一次不要配得太多,以恰好能用完為好,假如估計不準則寧少勿多,由于配好的膠過一段時間就會自行固化,造成浪費)。

三,配好膠后就可進進裱糊工作了。先用刷子(硬毛的刷油漆用的那種)將膠液刷一層在工件的內表面,然后將裁好的玻璃布壓貼在膠面上,用刷子輕壓使其緊貼及讓膠液滲透玻璃布;第一層玻璃布滲透后涂第二層膠,貼第二層玻璃布。裱糊時應考慮到安裝空間等因素,否則弄得太厚到時候裝不下就麻煩了。裱糊完后可找個安全的地方讓其自然固化,但需要的時間較長(視氣溫不同,要2-7天不等,溫度越高固化時間越短)有條件的可放產業烤箱或烤漆房里用120度烤2-4小時即可。也可放到溫度較高的地方以加速固化,但盡對不能用明火烘烤。待其固化后,修剪打磨毛邊,按原孔的位置尺寸開孔,對影響外觀的地方填刮膩子打磨噴漆后,玻璃鋼修補就完成。
