按木材改性工艺原理不同，防腐木主要分为防腐药剂注入处理的人工防腐木、热处理木材、含浸层积材等产品。人工防腐木因为经过化学处理一般略呈绿色。
According to the different principles of wood modification technology, antiseptic wood is mainly divided into artificial antiseptic wood treated with antiseptic agent injection, heat-treated wood, impregnated laminated wood and other products. Artificial antiseptic wood is generally slightly green after chemical treatment.
化学处理工艺流程如下：将经过窑干的木材放入加压处理罐；然后罐内抽真空，形成负压状态；注入防腐药剂；真空加压(保压)使防腐药剂渗入木材，从而达到深度防腐的效果；减压排出多余防腐剂；再次抽真空，排除多余防腐剂；防腐木制成出罐，再进行二次窑干或充分自然干燥。
The chemical treatment process is as follows: put the dried wood into the pressure treatment tank; Then vacuum the tank to form a negative pressure state; Inject antiseptic agent; Vacuum pressurization (pressure maintaining) makes the antiseptic penetrate into the wood, thus achieving the effect of deep antisepsis; Depressurize and discharge excess preservative; Vacuum again to remove excess preservative; Anticorrosive wood is made out of the tank and then dried in a second kiln or fully dried naturally.
防腐木按照树种分类如下：
Antiseptic wood is classified as follows according to tree species:
(1)樟子松：樟子松能直接采用高压渗透法做全断面防腐处理，其优秀的力学表现及美丽纹理深受设计师及工程师喜爱。俄罗斯樟子松防腐材应用范围极广，木栈道、亭院平台、儿童游戏区、花台、垃圾箱以及室外环境等项目均可使用。由于其独特的防腐工艺，所有的建筑作品都可以长期使用。
(1) Pinus sylvestris var. mongolica: Pinus sylvestris var. mongolica can directly use high-pressure infiltration method for full-section anti-corrosion treatment. Its excellent mechanical performance and beautiful texture are deeply loved by designers and engineers. Russian Scotch pine antiseptic material has a wide range of applications, and can be used in projects such as wooden plank roads, pavilion platforms, children's play areas, flower beds, garbage bins and outdoor environments. Because of its unique anti-corrosion technology, all architectural works can be used for a long time.
(2)赤松：赤松经过特殊防腐处理后，具有防腐烂、防白蚁、防真菌的功效。专用于户外环境，并且可以直接用于与水体、土壤接触的环境中，是户外园林景观中木制地板、围栏、栈道及其他木制小品的首选材料。
(2) Red pine: after special antiseptic treatment, red pine has antiseptic, termite and fungal effects. It is specially used in outdoor environment and can be directly used in the environment in contact with water and soil. It is the preferred material for wooden floors, fences, trestles and other wooden articles in outdoor landscape.
(3)西部红雪松：西部红雪松是北美等级最高的防腐木材。红雪松稳定性极佳，使用寿命长，不易变形。另外它也适用于高湿度的环境，例如桑拿房、浴室和厨房，用于制作橱柜、衣柜等可防蟑螂、蛀虫。
(3) Western red cedar: Western red cedar is the highest grade preservative wood in North America. Red cedar has excellent stability, long service life and is not easy to deform. In addition, it is also suitable for high humidity environments, such as saunas, bathrooms and kitchens, and can be used to make cabinets, wardrobes, etc. to prevent cockroaches and moths.
(4)黄松：其强度和比重最好，具有优异的握钉力，是强度最高的西部软木。经过防腐和压力处理的黄松，防腐剂可直达木芯。在安装过程中可以任意切割，断面无须刷防腐涂料。产品可以用于海水或河水中，绝对不会受到腐蚀。
(4) Yellow pine: It has the best strength and specific gravity, and has excellent nail grip. It is the western cork with the highest strength. After corrosion prevention and pressure treatment, the preservative can reach the wood core directly. During installation, it can be cut arbitrarily, and the section does not need to be painted with anti-corrosion paint. The product can be used in seawater or river water, and will never be corroded.
(5)铁杉：铁杉是目前北美市场上用途较广泛的树种。在强度方面，略低于黄松，比较适合做防腐处理。经过加压防腐处理的铁杉木材既美观又结实，堪与天然耐用的红雪松媲美。
(5) Tsuga: Tsuga is a widely used tree species in the North American market. In terms of strength, it is slightly lower than that of yellow pine, which is more suitable for anti-corrosion treatment. The hemlock wood after pressure corrosion treatment is beautiful and strong, which is comparable to the natural durable red cedar.
(6)炭化木：炭化木是应用高温对木材进行同质炭化处理，使木材表面具有深棕色的美观效果，它因防腐烂、抗虫蛀、抗变形开裂、耐高温性能成为户外泳池景观营造的理想材料。
(6) Charcoal wood: Charcoal wood is the homogenous carbonization treatment of wood at high temperature to make the wood surface have dark brown aesthetic effect. It is an ideal material for outdoor swimming pool landscape construction due to its corrosion resistance, insect resistance, deformation and cracking resistance, and high temperature resistance.
(7)柳桉木：通常分为白柳桉和红柳桉两种。白柳桉，常绿乔木，树干高而直，木材结构粗，纹理直或斜面交错，易于干燥和加工；红柳桉，木材结构纹理亦如白柳桉，切面花纹美丽，但干燥和加工较难。柳桉木在干燥过程中少有翘曲和开裂现象。柳按木木质偏硬， 有棕眼，纤维长，弹性大，易变性。
(7) Eucalyptus saliciformis: generally divided into two types: Eucalyptus saliciformis and Eucalyptus saliciformis. Eucalyptus alba, an evergreen tree, has a tall and straight trunk, thick wood structure, straight or oblique texture, and is easy to dry and process; The wood texture of Eucalyptus salix is also like that of Eucalyptus salix. The cut pattern is beautiful, but it is difficult to dry and process. There are few warping and cracking phenomena in the drying process of Eucalyptus. Willow wood is hard, with brown eyes, long fiber, large elasticity and changeability.
