What are the necessary conditions for the use of water-based paints for driving steel drums?

Introduction

In recent years, due to the emergence of haze weather, people are paying more and more attention to environmental protection and air polluti.

The starting point of switching water-based coatings - environmental protection

Waterborne coatings offer advantages in occupational health, safety and environmental protection (HSE) compared to solvent-based coatin.

First of all, water-based coatings use water as a diluent, and the concentration of organic solvents and toxic and harmful substances contained in them is greatly reduced, and the potential occupational hazards to painting workers are greatly reduc.

Secondly, water-based coatings use water as a diluent, and the risk of deflagration during storage and construction is almost reduced to zero, which greatly reduces the pressure on production safety manageme.

Third, the solvent content of water-based coatings can be reduced by 75% compared with traditional solvent-based coatings, the VOCs generated during the use of coatings are greatly reduced, and the corresponding emissions will also be reduced, thereby reducing environmental polluti.

From the perspective of HSE, the most important starting point is environmental protecti.

According to relevant research, VOCs are the main culprit causing haze, and coating is an important source of VO.

Necessary conditions for switching water-based coatings - meeting functional indicators

Coatings and their coatings are designed to meet certain functionalities, such as meeting the functional indicators of rust prevention, water resistance, oil resistance, high temperature resistance, decoration, e.

Therefore, even changing the model and brand of solvent-based paint is a very careful work, and a lot of testing and verification must be carried o.

In addition, some key functional indicators must be verified on specific products in addition to laboratory or sample verificati.

The ultimate driver for switching waterborne coatings - cost-effectiveness

Although water-based coatings have advantages over solvent-based coatings in terms of HSE, if the cost is too high, companies can only be discourag.

First, the price of water-based coatings is higher than that of solvent-based coatings;

The second is the investment in the transformation of the coating line, which increases the fixed cost;

The third is the increase in process cost caused by the preheating of water-based paint construction and the increase in drying ti.

However, the cost of these aspects is not necessarily high for different coating lin.
