Customer name: Nanjing Jinlong Bus Manufacturing Co., Ltd.
State of use: Body painting production line for large passenger cars, medium-sized passenger cars and logistics vehicles (annual output of 10 thousand vehicles).
Challenges: The bus body painting line is larger, and the number of washing water regularly needs to be discharged is large. The sewage treatment station cannot deal with it in time. At the same time, there are many kinds of materials on the bus body, which can not realize the collinear production.
major challenges: The bus body painting line is larger, and the number of washing water regularly needs to be discharged is large. The sewage treatment station cannot deal with it in time. At the same time, there are many kinds of materials on the bus body, which can not realize the collinear production.
Solution: The phosphorus free degreasing and silane products of KERUN company not only reduce the pressure of water washing in the field, but also meet the requirements of the production of the mixed material in the field.

Effect evaluation: After the use of KERUN company's phosphorus free degreasing and silane products in July 2016, some water washing sewage can be discharged directly, which greatly reduces the pressure of sewage treatment at the sewage treatment station. The KERUN degreasing + silane product pretreatment wastewater contains no heavy metal elements such as nickel and chromium. There is no P element in the sewage, which meets the requirements of environmental protection, and the amount of silane products is only 1/10 of traditional phosphating, which also reduces the cleaning frequency of plate filter press and the treatment amount of solid waste of phosphating products. It not only reduces the cost for customers, but also solves the problem of customer on-site sewage discharge is not up to standard.

The surface material of large passenger car and medium-sized passenger car is complex, and it is effective to solve the adaptability problem of vehicle body material. The residue of silane products is less, the range of pH value used is weak acid, and the cell cycle need is longer, which saves the cost for customers, and also facilitates the maintenance of site personnel. In the past 1 years, the quality of the products has been stable and has been well received by the customers.

The advantages of silane as compared with phosphating are as follows:

1、Environmental protection, energy saving, in line with the trend of development of countries and regions.

2、High stability, good electrophoretic matching and performance meet the requirements.

3、High adaptability of sheet metal, aluminum material can be treated with mixed material.

4、Phosphating residue, solid waste disposal site of low cost, convenient maintenance.

5、The cost of comprehensive operation is low.
