Study on prolonging the working time of silane solution during the silylation process on carbon steel

Abstract

Purpose

In the industrial silylation process, the cost of production can be greatly reduced by reducing the frequency of the replacement of the silane solution. The purpose of this paper is to describe how a method of discontinuous addition of concentrated solution into the KH560 treatment bath was developed, to improve further the effective availability of the silane solution and reduce cost of production.

Design/methodology/approach

The preparation and addition of each incremental amount of concentrated KH560 was studied in detail.

Findings

The results indicate that adding concentrated silane solution is an effective method of maintaining the target bath concentration.

Originality/value

The paper describes how a method of adding concentrated KH560 was developed to prolong the working time of KH560 solution for silane coating production, and to improve the availability of the KH560 in solution. The results indicated that adding concentrated solution was an effective method of prolonging the working time of the silane solution. The mixture ratio of the concentrated solution, and the volume of each incremental amount, both affected the performance of the KH560 solution.
