Unverified磁吸力强弱取决于面板背后的整块冷轧钢板厚度：优质款钢板≥0.3mm能吸住A4纸+3块磁贴叠加；铝合金或塑料背板款几乎无磁性，只能靠弱磁贴纸勉强吸单张薄纸84% similarUnverified带磁性的黑板贴通常是铁质基材+涂层，整体厚度约0.4-0.8mm且较重，需要更强背胶或另配挂钉，普通PVC黑板贴不具备吸磁功能78% similarUnverified磁性钢板板面比树脂板贵约50%且更重，但树脂板不吸磁、耐用性差，若只用于粉笔式记事而不需磁贴，树脂板足够77% similarUnverified磁性白板的磁力强弱取决于面板下方是否有整块镀锌钢板，边角贴磁性膜的'伪磁性'款只在中心区吸得住，选购看是否标注'整板磁性'77% similarUnverified壁挂白板承重与吸附力挂钩：钢板底材磁性吸附力强可挂磁贴字母卡，铝框PET面几乎无磁性只能写画；确认商品标注'磁性钢板'而非'磁性覆膜'77% similar
