Can High Temperature Conveyor Belt Resist Acid and Alkali at the same time?

Firstly, the temperature and PH value of the material are understood in detail. High temperature and acidity and alkalinity are important factors for accelerating the aging of rubber and losing its performance. The high temperature resistance performance is mainly styrene-butadiene rubber. For the conveyor belt industry, the operation process of styrene-butadiene rubber is relatively simple and the quality is stable. Styrene-butadiene rubber (SBR) has certain corrosion resistance to acid and alkali.

酸碱性主要影响橡胶本身的体积膨胀率,为了减少对橡胶性能的影响,会在输送带配方中添加一些惰性材料,惰性材料的作用主要是耐腐蚀,同时对橡胶拉伸性能影响不大,有效保证橡胶物理机械性能变化率。一般来说10%以下的硫酸是不会腐蚀橡胶的,10%硫酸的PH值为0,氟橡胶可耐98%的浓硫酸,也是常规橡胶中耐高温性能最好的。

Acidity and alkalinity mainly affect the volume expansion rate of rubber itself. In order to reduce the impact on rubber properties, some inert materials will be added to the conveyor belt formula. The inert materials mainly have the function of corrosion resistance, while have little effect on the tensile properties of rubber, effectively ensuring the change rate of rubber physical and mechanical properties. Generally speaking, less than 10% sulfuric acid will not corrode rubber. The PH value of 10% sulfuric acid is 0. Fluororubber can withstand 98% concentrated sulfuric acid. It is also the best high temperature resistance of conventional rubber.

橡胶输送带耐酸碱性执行标准:HG/T 3782-2005酸碱性能分为A1A2A3三种类别。

Rubber conveyor belt acid and alkaline performance standards: HG/T 3782-2005 acid and alkaline performance can be divided into A1, A2, A3 three categories.

 

橡胶输送带使用环境物料通常为弱酸碱性物质,在耐温的情况下是可以做到一定的耐酸碱。两种工况条件下,要根据现场更注重那种使用条件调整配方设计。

Rubber conveyor belts usually use environmental materials which are weak acid and alkali. Under the condition of temperature resistance, they can achieve certain acid and alkali resistance. Under the two working conditions, we should pay more attention to adjusting the formula design according to the field conditions.

比如很多输送物料有的温度在150度左右,且有一定酸碱性,可以调整配方,在耐热胶配方体系中加入惰性材料硫酸钡,硫化体系保持不变。另外骨架层的贴布胶尤为重要,因为高温加腐蚀性会大大加速橡胶老化,输送带长时间的接触物料会使覆盖胶物理性能变化较大、膨胀、变软,所有我们推荐大家用高段位标准天然胶提升贴布胶的附着力,保证输送带覆盖胶和骨架层不会出现脱层,大大的延长了输送带的使用寿命。

For example, some of the conveying materials have a temperature of about 150 degrees, and have certain acidity and alkalinity. The formulation can be adjusted. BaSO4, an inert material, is added into the formulation system of heat-resistant rubber to keep the curing system unchanged. In addition, the adhesive of the framework layer is particularly important, because the aging of rubber will be greatly accelerated by high temperature and corrosiveness, and the physical properties of the cover rubber will change greatly, expand and soften if the conveyor belt contacts with the material for a long time. Therefore, we recommend that you use high-level standard natural rubber to enhance the adhesion of the adhesive, so as to ensure that the cover rubber and the framework layer of the conveyor belt will not appear delamination, which greatly prolongs the transportation. Service life of belt conveyor.

另外橡胶输送带配方的设计一定要根据现场工况设计调整,青岛联众是一家专业生产橡胶输送带的厂家,与中国橡胶硅谷之称的青岛化工学院、符合教育部要求国家重点橡塑实验室有多方橡胶实验合作,确保产品使用质量稳定性,同时不断提升自身技术实力满足客户要求、更好服务大众。科学性、针对性的提供最合适橡胶输送带,使用过程中发挥最大的使用价值,从而降低客户的生产成本、检修成本等等。

In addition, the design of rubber conveyor belt formula must be adjusted according to the on-site working conditions. Qingdao Lianzhong is a professional manufacturer of rubber conveyor belt. It cooperates with Qingdao Institute of Chemical Engineering, known as China Rubber Silicon Valley, and the State Key Rubber and Plastic Laboratory, which meets the requirements of the Ministry of Education, in order to ensure the quality and stability of products, and constantly improve its technical strength to meet customers. Household requirements, better service to the public. To provide the most suitable rubber conveyor belt scientifically and pertinently, and to play the greatest use value in the use process, so as to reduce customer production costs, maintenance costs and so on.

青岛联众公司售前会安排技术人员前往现场进行工况察看、落实,并推荐最佳的输送方案供客户选择。

Qingdao Lianzhong Company will arrange technicians to go to the site to inspect and implement the working conditions, and recommend the best transportation scheme for customers to choose.
