                防腐木材质量检验的内容

                来源:http://www.jnajgc.com 时间:2022-07-02

                防腐质量检验的内容主要有两个方面:一是防腐剂的吸收量(用量),按每立方米或每平方米吸收防腐剂量计算,油类防腐剂以吸油量、油溶或水溶性防腐剂按干药量计算,二是药剂在木材中的透入深度和内层吸药量或浸透均匀度等。
                The content of anti-corrosion quality inspection mainly includes two aspects: first, the absorption amount (dosage) of preservatives, which is calculated according to the absorption amount of preservatives per cubic meter or per square meter; oil preservatives are calculated according to the absorption amount of oil, oil-soluble or water-soluble preservatives according to the dry dosage; second, the penetration depth of the agent in the wood and the absorption amount or penetration uniformity of the inner layer.
                吸收量;按防腐药剂的性质(如毒性和持久性等)、树材种、用途以及处理方法来确定防腐木材的吸收量。木材对防腐药剂的吸收较可以按处理前后木材重量差值,或在处理前后药剂的用量(消耗量)来确定。吸收量的规定与木材尺寸大小有关,以建筑材为例,规定氛化钠防腐剂以4-5公斤/立方米,是以中型木料(断面8 x 18平方厘米,长度250-300理米,表面面积50平方厘米)为准,一般小型木料的吸收量高,而大型木料相对地要稍少一些,采用涂刷、喷射以及涂浆青的扩散法的吸药量,按每平方米用药量计算。
                Absorption amount; The absorption amount of preservative wood is determined according to the nature of preservative (such as toxicity and persistence), tree species, purpose and treatment method. The absorption of wood to preservative agents can be determined by the weight difference of wood before and after treatment, or the dosage (consumption) of agents before and after treatment. The amount of absorption is related to the size of wood. Taking building materials as an example, it is stipulated that the sodium alginate preservative is 4-5 kg / cubic meter, which is based on medium-sized wood (Section 8 x 18 square centimeters, length 250-300 meters, surface area 50 square centimeters). Generally, the absorption of small wood is high, while the absorption of large wood is relatively less. The absorption of sodium alginate preservative by brushing, spraying and spreading method of paste blue is adopted, It is calculated according to the dosage per square meter.
                透人深度防腐剂从木材表面深入到内部的深度,这对合肥防腐木材的质量很有关系,尤其是边材部分要求透入到一定深度才能保障防腐质量,因为边材往往有可能潜伏感染的真菌。通常要求边材全透。
                The depth of penetration of preservatives from the wood surface to the interior is very important to the quality of Hefei preservative wood, especially the sapwood part requires penetration to a certain depth to ensure the quality of preservative, because sapwood is often potentially infected with fungi. Sapwood is usually required to be completely transparent.
                透入深度对深色的油类防腐剂可以从木材截面直接量得深度和边材厚度。对无色或浅色防腐剂可用化学显色剂处理。
                Penetration depth for dark oil preservatives, the depth and sapwood thickness can be measured directly from the wood section. Colorless or light colored preservatives can be treated with chemical chromogenic agents.
