Fiber cement coating board technology of six major elements

Fiber cement board and calcium silicate board coating process of six elements: process, substrate, paint, equipment, personnel, environment, six elements combination, become an essential element of the coating process, any one element is missing, will not be able to do a good product.

I. process determines the coating effect, method and product quality, is the first coating solution must be considered, is the most important factor. Good technology, will not qualify the substrate to make qualified products. A little bit simpler, it is the order of besmear outfit and technical requirement. A lot of people pay attention to equipment and coating only, do not care to craft, thought to should coating and equipment had been chosen only ok, as a result arrives later period because of craft different, and ceaseless change or increase decrease equipment, waste time and increase cost.

Substrate coating finish carrier, there are different density, flatness and quality of calcium silicate board and fiber cement board. Different quality of the substrate, coating process and equipment selection will also be different. Simple, calcium silicate board and fiber cement board.

Coating (paint) referred to as coating, the application of calcium silicate board and fiber cement board industry coating UV coating, water paint and paint fluorocarbon coating three categories. Coating types, equipment and drying methods are different. UV by light curing, water paint and paint fluorocarbon paint with hot air drying. As a result of coating technology, of colophony quality and recipe different, same kind of paint, the technical quality that different manufacturer produces also will differ with, the requirement to equipment and craft also will be different. Such as a roller coating film thickness will be different because of the solid content of paint and resin.

Four. Equipment coating tools, in addition to the quality stability, durability and convenient maintenance of equipment, also need to pay attention to the applicability of equipment, that is, the application performance. Different equipment also requires substrate and paint. The energy consumption, yield and safety of equipment should also be considered.

Five. Personnel coating the implementer, this is the only flexible element. The professional and experienced technicians can deal with the problems arising from the painting process flexibly, and at the same time can operate the machine to give full play to the maximum performance of the equipment. The shortage of skilled professionals is a common problem. Each enterprise must train several core technicians to operate and maintain machines and solve problems encountered in production or before they are solved.

6. The temperature and humidity of the environment will require the paint formula and the structure of the equipment (such as the heating of the steel roller of the roller coating machine). In particular, depending on the application environment, the process, paint and equipment will be different. Salinity, ph, water too much place, also have an impact on the plate. The northern climate has a long period of low temperature. The climate in the south is very hot and the environment is very long. This makes a difference between substrate and paint.
