全自动小型混凝土搅拌车滚道与托轮是搅拌车运输混凝士的重要部件，她的好坏直接影响到车辆的正常运行,下面小编为您讲解相关问题。
The raceway and supporting wheel of the fully automatic small concrete mixer are important parts of the mixer for transporting concrete. Their quality directly affects the normal operation of the vehicle. The following is a brief introduction to relevant issues.
1.硫酸酸洗法
1. Sulfuric acid washing method
搅拌车滚道硫酸酸洗法使用质量浓度为50~200克/升的硫酸水溶液，搅拌车滚道酸洗温度通常在60~80之间。硫酸是一种氧化性酸，其酸洗速度低于盐酸。有时，为了加快酸洗速度，超声波可以作为搅拌车滚道清洗辅助手段。
The sulfuric acid pickling method of the mixing car raceway uses sulfuric acid aqueous solution with a mass concentration of 50-200 g/L, and the pickling temperature of the mixing car raceway is usually between 60 and 80. Sulfuric acid is an oxidizing acid, and its pickling speed is lower than hydrochloric acid. Sometimes, in order to speed up the acid cleaning, ultrasonic can be used as an auxiliary means for cleaning the raceway of the mixer truck.
2.盐酸酸洗
2. Hydrochloric acid pickling
搅拌车滚道盐酸酸洗法采用质量浓度为50~200克/升的盐酸水溶液，搅拌车滚道酸洗温度通常在40以下。盐酸是一种还原性酸，具有很强的酸洗能力。搅拌车滚道清洗使用时，还可能导致氧化皮下金属基体的过度腐蚀。因此，在搅拌车滚道酸洗过程中经常添加尿素来保护金属基体。
The hydrochloric acid pickling method of the mixing car raceway adopts hydrochloric acid aqueous solution with a mass concentration of 50-200 g/L, and the pickling temperature of the mixing car raceway is usually below 40. Hydrochloric acid is a reducing acid with strong pickling ability. When the mixing truck raceway is cleaned and used, it may also lead to excessive corrosion of the oxidized metal substrate under the skin. Therefore, urea is often added to protect the metal matrix during the pickling process of the mixer raceway.
全自动小型混凝土搅拌车投入使用后,搅拌车滚道与托轮的理想状态是经过冷作硬化,搅拌车滚道与托轮摩擦面形成光亮的表面。
After the fully automatic small concrete mixer truck is put into use, the ideal state of the roller track and supporting wheel of the mixer truck is to form a bright surface on the friction surface of the roller track and supporting wheel after cold work hardening.
但由于用户对搅拌车使用操作不规范,加之制造过程中的缺陷,使得搅拌车滚道与托轮这对运动副在使用过程中达不到理想状态,表面会出现起皮划伤、沟槽等现象。更多相关内容就来我们网站http://www.zkzdsljbc.com进行咨询吧！
However, due to the user's nonstandard use and operation of the mixer truck and the defects in the manufacturing process, the moving pair of the mixer truck raceway and supporting wheel can not reach the ideal state in the use process, and the surface will appear peeling, scratching, grooving and other phenomena.
