Technical committee, special machinery sub-technical committee, and at the same time set up to set up a man-made stone working group. I also introduced the system framework of China's stone standards: stone (natural and synthetic) products, basic and test method standards, stone-specific auxiliary materials standards, stone-specific mechanical equipment standards, application technical specifications and management standards. At present, there are 48 current standards related to stone in China, including 23 national standards, 24 building materials industry standards, and 1 entry and exit inspection and quarantine industry standard, which does not include the relevant abrasives standards. There are 33 stone standards in the process of being revised. Among them, there are 16 national standards, 17 building materials industry standards, 23 new standards, and 10 industry standards. The next step is to formulate 20 national standards for artificial stone terms and test methods, and amend 7 national standards for stone test methods.
Director Zhou of the National Stone Inspection Center introduced to the participants that the recent standardization tasks after the establishment of the National Stone Standardization Technical Committee are mainly to: supplement and improve the standards urgently needed for the development of China's stone industry, and initially establish a more complete standardization system for China's stone. The medium and long-term standardization tasks are mainly on the basis of digesting and absorbing foreign advanced standards, supplementing and perfecting the stone standardization system, and promoting the technological advancement of the industry, strengthening management, energy saving, environmental protection, recycling economy, waste utilization, engineering safety, etc. Strengthen the research on stone standardization and the formulation of relevant standards.
Director Zhou finally emphasized that the formulation of the national standard for stone composite panels was carried out on the basis of the above-mentioned major environment, and it will definitely promote the healthy and rapid development of the stone composite panel industry as a whole. The future of stone composite panels will surely have great potential and a bright future, and encourage stone composite board enterprises. We must strengthen our convictions, refine our internal strengths, unite and actively make progress, and strive to open up the domestic market, and the national standards for stone composite panels will be officially introduced next year. In the future, we will surely usher in the rapid growth and development of stone composite panels!
The theme of the exchange meeting was after Zhou introduced the system of stone standards and the task of the near-stasis, mainly focused on the technical indicators of the specific content of the stone composite board from the industry standard to the national standard. . General Manager Liu Xuyu of Xindongyuan Stone Industry Company of Nan'an City, Fujian Province elaborated on the contents of the key chapters of the â€œNational Standard Recommendations for Natural Marble Reinforced Bricksâ€ submitted to the National Stone Materials Inspection Center. include:
(1) When the stone composite board is divided into wall surface and ground, the thickness of the surface material is divided into two types. (2) The flatness of the stone-tile composite board, can refer to the standard of the corresponding tile (3) Stone-tile composite board Whether the straight angle error can refer to the standard of the ceramic tile industry (4) Whether the surface material of the stone-tile composite panel can be set according to the high-quality surface material, and the inferior surface material is limited.
(5) Whether the radioactivity of the stone-tile composite panel can refer to the national standard of Class A of natural marble.
In response to the opinions and specific indicators of the general manager Liu Xuyu, the responsible persons of all enterprises actively and enthusiastically spoke and expressed their opinions and opinions. From time to time, some differences and disputes were generated. The atmosphere of the discussion was positive and enthusiastic. The meeting was fully communicated and discussed about these technical issues directly related to the actual production of each enterprise.
The Secretary-General of the Stone Composite Board, Bai Lijiang, also elaborated on the standard revision drafts and explanations submitted to the National Stone Material Inspection Center. The main points are as follows:
1. National standards should be more subdivided, more comprehensive, more rigorous, and forward-looking.
2. The reference standard should draw more reference to the relevant standards of composite board substrate.
3. Introduce several terminology specific to the stone composite board industry: empty drum, degumming, and air bubbles.
4. The classification is more detailed, and it is divided into 10 kinds of stone composite boards according to the type of substrate.
5. Mark the common type, production type, trend type of the example.
6. The thickness of the composite panel is divided into two types: wall surface (â‰¥1.0mm) and ground surface (â‰¥2.5mm).
7. Specify the number and size of empty drums and air bubbles in the bonding surface of the composite panel.
8. The physical performance indicators of the composite board are subdivided into indoor decoration (10 categories) and outdoor decoration (5 categories).
9. The composite panel exterior decorative adhesive is subdivided into structural adhesives and composite adhesives, and the physical properties of the composite adhesives are separately specified.
10. After the completion of the national standard, the technical specifications for the construction of composite panel curtain wall will be issued as soon as possible.

Quality, better promote the healthy and rapid development of the stone composite board industry!
What are the advantages of Laminate Flooring over those of solid hardwood flooring?
Laminate flooring is typically half the cost of traditional hardwood flooring. Additionally, laminate flooring is designed to be easy to install and is generally a good choice for most do-it-yourselfers, where solid hardwood requires a specific level of expertise. Installing laminate doesn`t involve nails, and more recently has done away with glue as well in many cases. Laminate flooring can therefore be installed fairly quickly and inexpensively. Laminate flooring is generally designed to be scratch-resistant and fade resistant, two areas where solid hardwood flooring is known to be more vulnerable.
