How to conduct quartz detection

Comprised under vacuum conditions in materials such as quartz, crystal, resin trace pigments made large size sheet by heterogeneous polymerization technology, its up to 94% of the quartz crystal as the main body structure, make the quality of a material is more hard, close together, with other decorative material wear-resisting, withstand voltage, high temperature resistant, corrosion resistant, anti seepage characteristics. The colorful combination gives it a natural stone texture a beautiful surface gloss. Quartz stone mesa has incomparable advantages of other materials, a generation is sought after by people, but because the technology is mature, only a few international manufacturers can produce quartz stone mesa, the price of quartz stone mesa is extremely expensive. Beflon enterprise has a strong r & D design ability, at the same time to achieve large-scale production greatly reduce the production cost, so that beflon quartz products prices compared with foreign advantages. At the same time as the production technology further mature, quartz stone will be more cost-effective than other artificial stone (resin price is much higher than the price of quartz), quartz stone is quartz content is higher, the lower the amount of resin, the better the quality, the more close to natural, the more difficult to deformation.

Identification of quartz stone standards:

The standard of quartz stone is still a blank in the domestic stone industry at present, all testing institutions can only refer to the standard of natural stone for testing, so the indicators of quartz stone are more than the standard of natural stone. The international standard for this aspect is still the ASTM standard of the United States. According to the foreign quartz stone test, we listed some of the following technical indicators of quartz stone, as a quartz stone identification standard:

1. Hardness: The mohs hardness of the surface is 7. The simple detection method is to observe the condition of the failure point by squeezing the metal tip, without scratching.

2. Density: 2.37-2.5

3, high temperature resistance: can withstand 300℃. Use a stainless steel cup filled with boiling water on the counter for 30 minutes. with a burning cigarette on the quartz stone, do change color.

4, pollution resistance: with soy sauce, vinegar, coffee drops on the quartz stone, 24 hours later with detergent water wipe, observation does change color.

5, environmental protection: can provide the authority of the green environmental protection certification testing.

6, fire resistance: with 10㎜ x 30㎜ quartz stone thin on the fire can burn.

7, acid alkali resistance: with 3% hydrochloric acid solution 100g/ L citric acid solution, 30g/ L sodium hydroxide potassium hydroxide solution etching surface, the surface has no obvious changes.

8, water absorption rate: less than 0.04%, sprinkle a little water on the surface of the quartz stone after 24 hours to observe the color of no whitening.

9, flexural strength: the standard is SN/T0308-1993, the test result of Befrion quartz is dry 40mpa, wet 44mpa.

10, compressive strength: the standard is SN/T0308-1993, the test result of Befrion quartz is dry 196mpa, wet 192mpa.

11, thermal expansion: the standard is SN/T17748-1999, the detection result of Befrion quartz is 0.18×10-4㎝/㎝℃.

12, radioactivity limit index (no radiation) : internal external exposure index conforms to GB6566-2001. The detection results of Befrion quartz were 0.02 for internal exposure index 0.03 for external exposure index.

13, brightness: detect more than 60 degrees with a light meter.

14. Appearance perception: clear cloudy. Even color. Flatness: 3000㎜ within ±0.5㎜; Thickness: 12㎜ plate ±0.5㎜, 15㎜ plate ±1㎜, 20㎜ plate ±1.5㎜.

15, specifications: Befrion quartz stone size to meet 3000㎜ x 1400㎜. Thickness of 15 mm, 20 mm, 30 mm, large volume plate ordering can produce 12 mm.

After reading so much, I believe that you have a certain understanding of quartz detection. If you want to know more information, please consult us.
