Unverified颗粒板（刨花板）承重和防潮不如多层实木板，单层隔板跨度＞90cm且放重物时易变形下沉，建议选择带中间立板支撑或隔板厚度≥18mm的款式89% similarUnverified板材厚度与承重正相关：实木隔板厚度<1.8cm在跨度超过60cm时中间易下垂，长隔板（80cm以上）应选厚度≥2.5cm或中间加装支撑89% similarUnverified隔板厚度直接影响承重：实木/多层板隔板厚度18mm以上抗弯性明显优于15mm以下，长跨度（宽度＞80cm）隔板中间无支撑时应选18-25mm厚板并加中间托87% similarUnverified板材厚度决定承重：18mm板材单层跨度≤900mm可放书籍杂物；跨度＞900mm或放置重物需25mm板材或中间加立板，否则3-5年后层板会明显下弯变形87% similarUnverified承重能力看层板材质与跨度：颗粒板层板跨度超过80cm时承重会明显下降，放置显示器+主机+功放的层板应选实木多层板或跨度≤60cm的颗粒板，单层承重需≥30kg86% similar
