Wood is a renewable resource that has been used as a material in appearance products for years. Despite its acceptable mechanical resistance, different modification processes were developed to enhance wood’s hardness and make it an even more durable material. Impregnating wood pores with monomers under vacuum-pressure cycle is a common method for that purpose. However, most implemented processes are long and mostly submerge wood into a monomer formulation (Bethell’s full-cell process). For that, they can be considered wasteful on the quantity of materials used, energy consumed and on process duration. The objective of this paper was to evaluate the parameters that influence the penetration of monomers into the tangential surface of Yellow birch (Betula alleghaniensis Brit.) samples. The analyzed factors were the monomer formulation’s viscosity, the surface temperature, the vacuum level applied to the process, the anatomy of samples, and the absorption time. After impregnation, the weight gain of the samples was calculated. Monomer penetration depth was calculated and visualized using density profiles and micro X-ray tomography imaging. Results showed that using a low viscosity monomer formulation allied to a certain level of vacuum and absorption time can considerably increase the impregnation into the wood.

木材是一种可再生资源，多年来一直用作外观产品的材料。尽管具有可接受的机械抗性，但仍开发了各种改性方法来提高木材的硬度并使之成为更耐用的材料。为此目的，在真空压力循环下用单体浸渍木孔是一种常用的方法。但是，大多数实施的过程很长，并且大多数将木材浸没到单体配方中（贝塞尔的全孔工艺）。为此，可以认为它们浪费了所用的材料数量，能量消耗和过程持续时间。本文的目的是评估影响单体渗透到黄桦（Betula alleghaniensis）切面的参数。英国）样本。分析的因素是单体配方的粘度，表面温度，应用于工艺的真空度，样品的解剖结构和吸收时间。浸渍后，计算样品的重量增加。计算单体穿透深度，并使用密度分布图和微型X射线断层扫描成像技术进行可视化。结果表明，使用具有一定真空度和吸收时间的低粘度单体配方可以大大增加木材的浸渍度。
