“…There are two methods for applying flame retardant treatment to wood: coating the wood with flame-retardant material and impregnating the wood pores with vacuum pressure [18,19]. Compared to coating, impregnation is a more beneficial method for introducing a flame-retardant effect of wood [20].…”

In accordance with regulations set forth by the Ministry of Land, Infrastructure, and Transport in Korea regarding the "Flame Retardant Performance of Building Finishing Materials and Fire Spread Prevention Structure," it is mandated that semi-noncombustible materials have a total heat emission less than 8 MJ/m2. Consequently, our study aimed to determine the ideal quantity of flame-retardant treatment required to meet the fire safety standards for Korean larch and Japanese cedar, commonly used exterior materials in Korean construction. To this end, we investigated using a cone calorimeter to observe changes in the THR (Total Heat Released) based on the AFI (Amount of Flame-retardant Impregnation) in Korean larch and Japanese cedar. Our findings indicated that the AFI needed to satisfy the prescribed flame-retardant standard of 8 MJ/m2 was THR 299 MJ/m2 for Korean larch and THR 526 MJ/m2 for Japanese cedar. As a result, we established optimal impregnation levels of flame retardant for both species.

“…One method of wood modification is impregnation, a process through which a molecular compound is penetratedinto the wood structure and there by increases the density and hardness of the wood. Impregnation of organic and inorganic compounds into wood structure by soaking or using vacuum pressure tube can be performed to improve physical properties of wood (Hadi et al, 2018;Hartono et al, 2016;Oh and Park, 2015).…”

Jabon (Anthocephalus cadamba) is a fast-growing wood species that is widely utilized for light construction and other purposes in Indonesia. The objectives of the current study were to determine the effects of monoethylene glycol (MEG) and SiO 2 nanoparticles (nano SiO 2 ) impregnation treatment on the dimensional stability and density of jabon wood and to identify the characteristics of impregnated jabon wood. Wood samples were immersed in water (as untreated), MEG, 0.5% MEGSiO 2 , then impregnated by applying 0.5 bar of vacuum for 60 min, and then applying 2.5 bar of pressure for 120 min. The results showed that impregnation with MEG and Nano SiO 2 had a significant effect on the dimensional stability of jabon wood. Polymers can fill cell walls in wood indicated by increasing weight percentgain, antiswelling efficiency, bulking effect, and density, then decreasing in water uptake value. Jabon wood morphology by using SEM showed that MEGSiO 2 polymers can cover part of the pitsin the wood vessel wall of jabon. This finding was reinforced by EDX results showing that the silicon content was increased due to the addition of SiO 2 nano. The XRD diffraction pattern indicated that MEGSiO 2 treatment increased the degree of crystallinity in wood samples. Overall, treatment with 0.5% MEGSiO 2 led to the most improvement in the dimensional stability of 5-year-old jabon wood in this study.

“…To improve physical and mechanical properties and its resistance, impregnation of organic and inorganic compounds into wood structure by soaking or using vacuum pressure tube can be performed (Hadi et al, 2018;Hartono et al, 2016;Oh and Park, 2015). Wood vinegar as a by-product from pyrolysis process of ligno-cellulose biomass can be applied as organic impregnant (Bridgwater, 2012;Lee et al, 2011;Tiilikkala et al, 2010).…”

Jabon (Anthocephalus cadamba Miq.) is a fast-growing species that exhibits a lower natural resistance than that exhibited by the timber sourced from natural forests. Jabon's resistance to termite attack can be improved by impregnating its wood structure with poisonous organic materials. This study examined jabon's resistance to termite attack when impregnated with wood vinegar and an animal adhesive. The wood specimens were impregnated using sengon wood vinegar and an animal adhesive (8% and 10%, respectively) using a vacuum pressure machine. The specimens were tested for their resistance to subterranean and dry-wood termites according to Indonesian National Standard (SNI 7207-2014). The results denoted that jabon impregnated with wood vinegar and an animal adhesive concentration of at least 8% with the addition of 4% borate was effective to resist termite attacks. The impregnated jabon exhibited a lower weight loss and higher termite mortality when compared with those exhibited by the control specimens. Thus, the resistance class improved from class IV to class I.
