Unverified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90% similarUnverified实木隔板厚度直接决定承重与抗弯变形：厚度＜1.5cm的板材放重物易中间下沉弯曲，跨度＞60cm的隔板厚度应≥1.8cm或中间加支撑88% similarUnverified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86% 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85% similarUnverified板材优先选双饰面刨花板（颗粒板）E1级及以上或密度板，厚度≥18mm；层板承重与厚度直接相关，18mm层板单格净跨度＞60cm时长期放重物会中间下弯变形85% similar
