1.实木
1. Solid wood
其实它有着天然的质感和色彩,醇厚的质感和独特的审美特征。建筑模型中使用的实木属于教育树种,如杨树、杉木、桃树、样木、枣树、橡树、松树等。柚木、檀香木等硬木可用于有特殊工艺要求的电力。现代实木材料一般都是预制加工成型材,经过严格的脱水处理,不变形,不起泡,购买方便。主要的实木型材有板材、板材、棒材和成品配件。
In fact, it has natural texture and color, mellow texture and unique aesthetic characteristics. The solid wood used in the building model belongs to educational tree species, such as poplar, fir, peach, sample wood, jujube, oak, pine, etc. Teak, sandalwood and other hardwood can be used for power with special process requirements. Modern solid wood materials are generally prefabricated and formed materials. After strict dehydration treatment, they are not deformed, foamed and easy to buy. The main solid wood profiles are plates, plates, bars and finished accessories.
2.胶合板
2. Plywood
胶合板是将原木旋压成单板或用木方刨成薄木,然后用粘合剂粘合而成的三层或三层以上的薄板。通常是奇数号的单板,相邻单板的纤维方向垂直排列,胶合在一起。所以有三合板、五合板、七合板等奇数合板。胶合板具有天然木材的所有优点,如重量轻、强度高,质感美,保温等。并能弥补天然木材的一些天然缺陷,如结疤、宽度小、变形、纵横力学差异大等。
Plywood is a thin sheet of three or more layers formed by spinning logs into veneers or planing logs into thin wood, and then bonding with adhesives. Usually odd numbered veneers, the fibers of adjacent veneers are arranged vertically and glued together. Therefore, there are odd plywood such as three plywood, five plywood and seven plywood. Plywood has all the advantages of natural wood, such as light weight, high strength, beautiful texture, thermal insulation, etc. It can also make up for some natural defects of natural wood, such as scarring, small width, deformation, large difference in vertical and horizontal mechanics, etc.
3.木芯板
3. Wood core board
这种芯板又称细木工板或大芯板,是一种实木芯的胶合板。它是将原木切割成条状,拼接成芯,外表面覆盖单板制成的。其竖向(按芯板方向区分)抗折抗压强度较差,但横向抗折抗压强度较高。根据加工工艺,芯板可分为机器拼接和手工拼接两种。手工拼接是将木条手工插入胶合板中,木条挤压力小,拼接不均匀,缝隙大,握钉力差,不能锯,只适合整体拼接。而机拼板压力较大,缝隙极小,拼接平滑,承载能力均匀,且结构紧凑,长期使用不易变形。木芯板可分为杨木、杉木、松木等。优良板材表面光滑平整,不易翘曲变形,根据砂光情况可分为两种。
This kind of core board, also known as Blockboard or large core board, is a kind of plywood with solid wood core. It is made by cutting logs into strips, splicing them into cores, and covering veneers on the outer surface. The vertical (according to the direction of the core plate) flexural and compressive strength is poor, but the transverse flexural and compressive strength is high. According to the processing technology, the core plate can be divided into machine splicing and manual splicing. Manual splicing is to manually insert the wood strip into the plywood. The wood strip has small extrusion force, uneven splicing, large gap and poor nail holding force. It can not be sawed. It is only suitable for overall splicing. The machine splicing plate has large pressure, small gap, smooth splicing, uniform bearing capacity, compact structure and not easy to deform after long-term use. Wood core board can be divided into poplar, Chinese fir, pine, etc. Excellent plate surface is smooth and flat, not easy to warp and deform. It can be divided into two types according to sanding.
木芯板螺旋力好;透气性高、品质强、吸音、隔热等特点,且含水量不高,一般为10%~30%,加工简单。这个板子比实际板子更稳定。其规格为(长/宽)2440mm*1220mm,厚度为15mm~18mm,在模型制作中,一般采用切割机进行加工。
Good spiral force of wood core board; It has the characteristics of high air permeability, strong quality, sound absorption and heat insulation, and the water content is not high, generally 10% ~ 30%, and the processing is simple. This board is more stable than the actual board. Its specification is (length / width) 2440mm * 1220mm and its thickness is 15mm ~ 18mm. In model making, it is generally processed by cutting machine.
