Himonia wood coating smoke suppression and flame retardant system operating specifications

The UV flame retardant system is a new system compared to the conventional UV coating system, especially in terms of testing methods, which use burning to test performance and classification. The burning testing method is much better than traditional testing methods (such as cross-hatch adhesion, etc.) It is much more destructive. Therefore, during the coating construction of the flame retardant system, we found that the flame retardant function cannot be achieved simply by replacing it with oil-retardant coating and as long as the flame-retardant coating coating amount reaches the standard. In the process and coating There are many aspects to pay attention to in the matching.

The most common problem in the combustion test is the explosion or delamination of the coating film after burning. The factors causing these problems are the adhesion and bonding strength of the coating film, including the coating film and the substrate, and the gap between the coating film layers. Adhesion.

Factors that affect adhesion include the flexibility of the coating film, the degree of solidification of the coating layer, the polishing effect, and the most important factor is the coloring depth or color coating process of the coating film. The darker the color; as well as the gray and white series or the Grace process, in which a large amount of white slurry is added or a water-based white primer is directly applied; in the color coating process, the layer connection between the color coating and other coatings, these factors will affect the quality of the coating layer. Structure and adhesion have a great influence on the flame retardant performance. Paint explosion and delamination will occur during combustion tests.

The following is a brief description of the process:

Operation procedures of Himonia wood coating smoke suppression and flame retardant system

★Process 1: Water-based base coloring is the most critical. Whether it is regular color coloring or adding white, the proportion of color addition must be strictly controlled. If the color is too dark, it can be separated into subsequent coatings for color correction; for water-based white base, select a specific model for construction. Cycle in small to medium amounts and add new coating frequently

★Step 2: Do not choose an adhesion primer that is too soft. If it is too soft, the coating film will easily curl and delaminate in the adhesion primer during the combustion test; adding a curing agent to the adhesion primer will help.

★Process Three: In the middle layer, pay attention to the curing energy or sanding effect of each coating layer. These two factors will lead to poor adhesion between layers; continuous construction of the flame retardant layer will have better flame retardant effects and be controlled according to the needs of the combustion level. Coating amount of flame retardant coating

★Step 4: The first topcoat can be appropriately colored to reduce the concentration of water-based base coloring.

Some suggestions on the operation of coating smoke suppression and flame retardant systems

1. For new processes or new samples, please conduct process verification first to confirm the combustion effect before mass production.

2. It is recommended that customers conduct simple combustion quality inspections during the production process

3. It is recommended that the finished product be sent to a third party for testing
