Introduce the maintenance precautions of marbled melamine paper

Introducing the precautions for the maintenance of marbled melamine paper 1. Considering from the user's point of view Since marbled melamine paper is a microporous material, it is easy to absorb dirt and water. In daily life, first of all, it is necessary to establish a cleaning and wiping method that uses less or no water as much as possible. (such as using electrostatic dust to push oil or a slightly damp mop), and try to avoid all kinds of oil spilling and infiltration (if conditions permit, you can do marble oil-proof treatment in advance); when there are hard objects or sharp objects to drag, please use a cart or A soft cotton cloth, paper shell, etc. should be placed under the object. To avoid the walking friction of the outside sand on the marble, then use a dust pusher or a vacuum cleaner to often push the dust in the walking area, thereby effectively avoiding fine scratches. 2. From a professional point of view, in order to strengthen the hardness, density, wear resistance, and antifouling of the surface stone: strengthen the hardness of the stone surface through chemical materials (such as wax coating, reconstruction of crystal surface, resin coating, paste curing, liquid curing) agent). 3. Considering from the perspective of economy and applicability A. Waxing maintenance: It belongs to the process of 15 years ago and is basically eliminated now, because the wax water is easily hydrolyzed and easily polluted, and it will cover the gloss of the marble itself, and the hardness of the wax itself Softer, coupled with the high cost of waxing, cleaning and re-waxing in the later stage, this kind of maintenance method has almost withdrawn from the stage of professional stone maintenance. B. Reconstructed crystal surface: This is the most used marble maintenance method in China in the past 10 years. Its basic principle is to put some chemical materials under the mirror maintenance machine with a weight of more than 65 kg, and use the polishing machine driven by the rotation of the machine. The heat formed by the friction of the pad (or silk cotton) on the ground produces chemical bonding and micro-rheological reflection with the marble surface structure and tissue, and through the dual action of grinding and filling, a harder and brighter blend is re-formed on the marble surface. Crystal layer, this crystal layer can improve the strength and wear resistance of marble, and at the same time can peel off part of the aging layer, this is why the stone crystal surface reconstruction can continue to be used and is still favored by domestic and foreign users; and In the process of crystal surface reconstruction, there is no need to close the site, and you can go as you do, and the economic performance of materials, cost, and labor is the most economical type among various maintenance methods. The material states of crystal surface reconstruction are: solid, powder, water, slurry, paste (will be discussed below) and other forms, but they all belong to the category of crystallization. C. Paste curing: Based on the above-mentioned crystal surface process, some domestic and foreign manufacturers have designed a crystalline material that combines nano-molecule + water-soluble resin and silicon molecule into paste, which can continue to be called paste curing (some people call it sealing glaze, others call it Coating), the principle is to rub the paste material on the marble surface or the surface of the polishing pad, through the weight of the low-speed polishing machine and the heat generated by grinding, the nano-molecules, silicon molecules and resin components are gradually rubbed into the molecular pores of the stone. Internal and solidified to the surface layer and form a solidified layer with a harder texture to improve the surface brightness, wear resistance and stain resistance of marble; however, due to the high rate, material and labor intensity of operating such paste crystallization , This method is more economical and cost-effective than the principle of crystal surface reconstruction, and the filling performance of this process is high and the grinding performance is low, so it is not applicable to some stones with serious weathering and poor surface smoothness. D. Liquid curing agent: This type of maintenance method is suitable for infiltrating the interior of the stone during the renovation and repair of the marble, which can strengthen the loose marble. Therefore, the maintenance of the crystal surface alone cannot be used independently. Hard - grinding - fine grinding - polishing - crystal face reconstruction can be completed, which will be discussed in the refurbishment process (not part of the daily crystal face reconstruction process).
