Epoxy resin to make up for deficiencies marble

China Stone Association, the Association of Italian marble, the International Association of Marble, Italian Trade Commission held four units in Xiamen stone processing technology and equipment workshops, attended by representatives of the Italian side for the Italian stone machinery manufacturers on behalf of the Italian side at the seminar on behalf of their introduction on the history of the company's stone machinery and mechanical type of stone, from stone rational exploitation, processing, polishing, and maintenance and a series of processing technology and equipment needed to make more in-depth understanding of Chinese businessmen Italian stone machinery cultural history and related machinery performance, use, and stone machinery development. Italy on behalf of Mr. Paul was highlighted because in the past often fill Te polyester marble containing benzene, phenol and harmful substances, the international market requirements for increasingly stringent environmental protection stone, will be phased out, and epoxy resin as Marble filler to make up their own shortcomings, an advanced processing technology, this process is characterized by:
1, White marble waterproof, oil-enhanced;
2, the mechanical tensile strength, compressive strength enhancement;
3, grinding and polishing to improve the surface finish;
4, effectively brought to make up their own material, for example, more uniform color, more beautiful.
Specific processing is divided into three processes:
First, the surface of the pre-cast
Marble confers loose tissue, by cutting the surface flatness is poor, so when the glue, polished after the resin can not effectively attached to the stone surface and cracks, less than the desired effect, usually marble, pre-cast abrasive 1,2 to the basic flat surface, convex surface can not come 0.20mm.
Second, clean and dry
Stone surface by the residual powder after grinding and abrasive mixture, which will be attached to the stone dust surface and hinder the combination of epoxy resin and stone, and there is dust affect the quality of color, common methods are: using a brush or rinse with high pressure water washing (This method can not be suspended sheet), brush the stone surface and can effectively remove the dust inside the gap, the resin to increase contact surface with the stone, but because the water will flow into the stone cracks, the presence of water deeper into the stone pores hinder the resin, the plate need dry cleaning or drying, but the conventional dry method will still have water left in the stone pores, precipitation for water my house, tunnel or tower two kinds of drying equipment for drying, the test at 45 degrees 55, time 120 minutes, but the different materials using different time controls, the more porous material, the shorter drying time, the gap in water after drying completely, if the conditions can make glue side while a vacuum suction out the gap air, so that resin can move deeper into the gap, the better.
Third, the shop epoxy resin, curing polished
Epoxy and pour melted by heating the surface of the stone commonly used artificial evenly in the stone surface, smear Baidu in 0.50mm to 1mm, smooth out the process to put some pressure on the resin into the gap, such as the use of automated machinery Ohira layer, After the resin into the dry stone tiled container, container spy control 30 to 40 degrees, for about 120 minutes, controlled by computer, can not be shaken, as to be stationary at room temperature for 24 hours, the resin can be completely cured, resin and the material to be together as one, this glue process all complete, after the marble through the glue after the mechanical strength by grinding and polishing to improve, more uniform color, bright.
At present, domestic stone industry competition, lower profits, whether domestic colleagues used this process to improve the quality of our marble, and enhance the competitiveness of the country girl, occupy a certain share of the international market, revitalization of China's stone industry.
