The difference between the quartz die casting plate and the ordinary casting plate

Quartz stone, from the production process, said there are two kinds, one is a die casting, one is cast plate. Die casting plate, as the name suggests, is a series of procedures, such as high pressure, high shock, high temperature, etc., because the production process, its hardness and the proportion is relatively high. Anti seepage, anti cracking, heat resistance, scratch resistance are very good. The production process of the casting board is from the original artificial stone production process improvement, the raw material through the mixing directly into the mold and vacuum forming. The density and hardness of the high pressure, high pressure and high shock without high temperature and high pressure are relatively low. Anti seepage, anti cracking, heat resistance, scratch resistance is relatively poor. Consumers want to distinguish between casting and die casting plate, you can start from the following aspects:
1, hardness, casting board hardness is lower than 4, while the hardness of the die casting is equal to or higher than 6, Rongda quartz stone hardness higher than 6.
2, proportion (also known as the relative density, the density of the material and in the standard atmospheric pressure, 3.98 degrees pure H2O (999.972 kg / m3) density ratio), casting in the proportion of less than 2, stone casting in the proportion of more than 2.4, in full compliance with the quartz die casting industry standards.
3, the environmental performance, the casting board is a natural curing, without any treatment, the chemical composition of the material on the human body pose a hazard. The die casting plate is OT curing and high temperature urging curing, to stay in the material inside the chemical composition of all the high temperature treatment, is absolutely environmentally friendly. Therefore, Rongda die casting plate has been to environmental protection and the consumer's trust.
4, the appearance of the casting plate of the larger particles, and the distribution of particles is not uniform, the back is very obvious than the positive. The particles of the die casting plate are uniform and the distribution is uniform.


Quartz stone ten major brands

Quartz is a physical and chemical nature of mineral resources are very stable, mainly refers to the distribution of a wide range of three party system of low temperature quartz (alpha quartz). When the temperature is above 573, the high temperature of the six party system is the high temperature of the quartz crystal. Low temperature quartz crystal is six square column with spire. Have stripes on the cylinder, there is difference between left and right shaped crystal crystal shape. Twinning is common, the most common for the Dauphine twin and Brazil twins. Usually a crystalline or granular, lump aggregate.

(4)Quartz  with strong piezoresponse property), namely banged the friction will produce a spark. This is flint stone.
(5) inclusions of quartz in common: hair crystal - mainly rutile; grass into the crystal - mainly for tourmaline; water bile crystal quartz liquid inclusions; green quartz - containing shallow blue needle like rutile material; milky quartz - by fine water holes caused by mixed cloud; green quartz by debris or tabular chlorite composition, sometimes green needle actinolite; Aventurine Aventurine  quartz rocks containing green or reddish brown mica flakes, also known as Yao quartz, commonly known as Tanglin stone. Common smoke black to dark brown smoke crystal, mainly in these rocks contain more quantities of radioactive uranium, thorium elements of the relationship.
Characteristic
1, scratch
The quartz content of up to 94%, quartz crystal is nature in hardness only to diamond's natural mineral, the surface hardness can be up to 7.5 Mohs hardness, far greater than the kitchen knife blade, and other weapons and will not be scraped.
2, no pollution
Quartz stone is made under the condition of vacuum qulity, dense non porous composite, has an excellent corrosion resistance ability of the quartz surface of the kitchen, pH and other, daily use liquid substances will not penetration inside, placed on the surface of the liquid for a long time only need water or clean and bright and cleaning agent with a rag wipe can, when necessary, use the blade to scrape the surface of the retentate.
3, with no old
The surface of the quartz stone is shiny and beautiful is after 30 multi-channel complex polishing treatment process, will not be knife blade scratch, will not be penetrated by liquid substances, will not produce a yellowing and discoloration problems, daily cleaning only needed water rinse, simple and easy. Even after a long time of use, the surface is as bright as new mesa, no need for maintenance.
4, burning
Natural quartz crystal is a typical refractory material, its melting point up to 1300 degrees Celsius, quartz stone made of 94% natural quartz is completely flame-retardant, not due to exposure to high temperature and lead to combustion, also have the man-made stone mesa incomparable high temperature resistant characteristics.
5, non-toxic no radiation
The surface of quartz stone is smooth, flat and smooth, no scratches, and the structure of the dense and porous material makes the bacteria have no place to hide!
Selection of natural quartz crystal mineral is employed for the high-quality quartz stone, the SiO2 content of more than 99.9%, and in the manufacturing process to purify and raw material does not contain any radiation metal impurities may lead to. 94% of quartz crystal and other resin additive makes quartz no radiation pollution risk.
Main purpose
The main material of the quartz stone is the quartz, the color rich combination makes it has the natural stone material the texture and the beautiful surface gloss. The colors of quartz countertops are varied, Gobi series, crystal series, granite series, flash star series more features can be widely used in the field of public buildings (hotels, restaurants, banks, hospitals, exhibition, laboratory, etc.) and home decoration (kitchen countertops, vanity units, kitchen walls, tables, coffee table, window, door, etc.), is a free of radioactive pollution, can be repeated use of environmental protection, green building new indoor decoration materials. It should be pointed out that the quality of quartz stone with the content of the resin content has a direct relationship. The higher the content of quartz, the lower the amount of resin, the better the quality, the more close to the natural, the more difficult to deformation. Experts point out that when the content of the resin in the quartz stone is more than 10%, the corresponding technical indicators will fall, then the quartz stone can not be called a real quartz stone.


Quartz Processing And Installation Process

The processing method of the quartz is approximate to the natural granite, which is very different from the common "artificial stone" in the present market. All operations must be cooled with water.

Various Grades And Ranks of Quartz

Many customers, including novices, generally judge quartz the strengths from weaknesses by the most direct method, which is using sharp things (such as steel nail) to draw the surface, if it is a thin black line, and can be no trace by hand wiping, getting that this is good quartz plate, otherwise, if delimits the trace, a white powder fall, then can’t be thought the real quartz.
In fact, judge the pros and cons of quartz, not just by looking at the scratch, in addition, there are quartz gloss, texture, quartz sand, etc.. In terms of gloss, depends on the material and its production process, really good plate, its gloss by touch, is very fine, soft and smooth. This need to use a different product to compare to feel.
So judge whether the quality of the quartz plate, also need our intentions to see, to compare to find the details inside.


Origin of Quartz

In China, except for Shanghai and Tianjin city, other provinces, cities, and autonomous region have output for crystal, quartz ,and natural silica sand. There is better quality of ones in Guangdong, Guangxi, Qinghai, Fujian, Yunnan, Sichuan, Heilongjiang and other provinces; and the best of in Hainan and Jiangsu. The main source for crystal, quartz vein in Jiangsu Province is Donghai County. Natural quartz crystal and quartz in Donghai County have rich reserves. According to the geological prediction team six in the Jiangsu Province,  The content of SiO2 in natural crystal is up to 99.9983%, and its quality and reserves is NO.1 in China.
Crystal, quartz vein mining in Donghai County has a long history. In 1958, people in Fang Shan Zhen zhe Tang Cun, had mined single crystal weighing 3.5 tons "Crystal King", 1982 hump Xiang Nan Liu Cun minied single crystal weight 2.1 tons (were deposited in the Geological Museum of China in Beijing), caused popular attention at home and abroad. According to the statistical data for many years of Ministry of geology crystal management office, which  confirmed that Donghai County Crystal acquisition accounted for more than 50% of the crystal yield (Table 1 shows the 105 mine of Donghai County Crystal from 1973 to 1988 acquisition volume), and raw materials for crystal coffin of Chairman Mao Zedong was supplied by the East China Sea, Donghai County is the famous "township of the crystal”.
Due to the reserves of crystal, quartz vein, quartz gravel, natural silica sand, quartzite and quartz powder ore belong to non pillar mineral resources in the national economy of China ,and it is also a variety of non - metallic mineral deposits in China, so the national reserves are mostly in the prediction and estimation, in the exploitation and use of the principle of sustainable development


How to Choose a High Performance And Stylish Cabinet

1 Hardness: artificial quartz content in more than 93% quartz sand, inferior product resin content is too high. With a knife and the like the hard thing to scratch quartz, the high quality quartz stone plate will not be scratched.
2. High temperature resistance: we can use a cigarette, directly to hot quartz stone plate surface, but Shuo cigarette burn not leave any trace in the high-quality quartz stone layout.
3 .Anti corrosive: high-quality quartz stone undoped marble or granite powder, these minerals are calcium carbonate components, with a certain proportion of acid drops in quartz stone plate surface, high-quality quartz stone plate will no response.
4. Anti pollution performance of the board: anti pollution performance of poor quality quartz stone is poor, soy sauce, vinegar and so on, which stay on the surface of quartz countertop may be difficult to clean on a day. When purchasing you can use the water pen to leave a scratch in the quartz countertop, the high quality quartz stone ,only need to use a cloth to gently wipe on the restoration of bright then as new, completely without leaving traces.
5. Pay attention to plate cracking performance: due to the quartz stone plate content in more than 93% quartz sand, high hardness, and high brittleness ,low toughness in the same time. When the material is unable to withstand the internal stress of the thermal expansion and contraction will  occur to crack. Therefore, choose a high anti cracking performance of quartz stone.
6. The texture, color and overall kitchen collocation is very important: from the point of view of the texture of the plate, the quality of quartz stone is close to natural stone, poor quality of one has a strong exterior plastic sense. High quality quartz has color saturation and rounded, bright color, uniform particles, especially the complex color palette, is smooth and clear. To consider the table and kitchen door color, floor pattern and other space of the overall style of collocation when choosing the color.

 7. Table processing technology: to buy cabinets, look at the cabinet like version of the table, a good processing technology, the connection is very perfect, almost has no connection seam. The unqualified processing will lead to the failure of the countertop surface, the rough processing technology also affect the appearance of the table.
