Production and Application of Quartz Stone

From: 2016-3-22 0:04:59      Brower:

Quartz is a kind of no radioactive contamination, reusable, environmental protection and green new building material. It is based on unsaturated polyester resin (UPR) or methyl acrylic (PMMA) and organic polymer materials as the substrate, quartz powder, granule, etc, as filling material, add with pigments and other adjuvant . It’s a polymer composite materials after vacuum high pressure molding.

The composition and production technology of quartz

 Unsaturated polyester resin: resin is the raw material of quartz, for bonding and curing. Currently, the regular resin for making quartz are types of orthophthalic, isophthalic,  neopentyl glycol, isophthalic/neopentyl glycol, Vinyl ester, acrylic acid and etc.

Filling material: Main ingredient of quartz filler is silicon dioxide, including: quartz sand, quartz powder, glass fragments. Mainly function: Firstly, filling volume; Secondly, to enhance quartz stone texture; Thirdly, enhance the mechanical performance of quartz; Fourthly, act as an accelerant.

Pigment: The role of pigment in the quartz is formulated designs and varieties to rich the colors, in theory, any color can be concocted by various pigments.

Curing agent: curing agent is essential for the production of quartz additives, high quality quartz is molded by high temperature curing.Curing agent: curing agent is essential for the production of quartz additives, high quality quartz is molded by high temperature curing.

Other additives: resin belongs to the family of polymer materials, adding appropriate amount of some additives can improve its technological capability, enhance production efficiency, improve the performance of quartz and prolong its life.

Production process: First, Crushing high quality natural quartz sand. Then, purify (this process can eliminate the metal impurity, prevent the quartz from radioactive), third, mixing raw materials. Mixing quartz crystal (90% -94%), resin (6%) and few pigment etc by heterogeneous polymerization technologies under vacuum conditions to make a large size slab, then polishing its surface by more than 30 procedures.

Quart stone application range and development direction

At present, the main application of quartz stone are kitchen table-board, bath-room mesa, bar countertop, tea table, floor and interior wall etc. It will replace the natural stone, high-grade ceramics, wood, metal decorative materials completely. At the same time, the quartz stone become the substitute products in the cabinet industry, the proportion of the quartz stone application, such as floor decoration is greatly increased. Due to the high hardness of quartz stone, which reaches mohs 5-7 degrees, this will bring difficulty to quartz processing technology. Personalized consumption of the cabinet industry, required a high cabinet modeling technology, any negligence may leave stain, the hardness also has a higher demand on the joining technology of quartz.

Quartz countertops, refers to the cabinet countertop made of quartz. Quartz table top
is made of glass fragment and quartz sand. The advantage of quartz is wear-resisting,
scratching resistance, heat resistance. It can be used for large area paving
and wall decorating, make various kitchen countertops, joining together
seamless splicing, which is durable. Quartz stone is a new type of
environmental-friendly stone, synthetic by 93% natural quartz combined with
resin and other additives components.

As a ombination of natural beauty and high technology, it is a complete new surface
decoration material, which is made of quartz crystal mineral. This kind of quartz
crystal mineral itself has a natural features of clear, nice hue, luxurious,
high hardness, no distortion, no discoloration, strong toughness, non-radioactive,
resistant to acid, which is known as "jade mine".

Quartz stone uses the plane material made of those raw material, gather both the advantages  of natural stone and artificial stone in itself. It has been already widely chosen by customers in most countries, including European countries, America, Australia, and the Middle East countries., they all feel proud to use quartz for their decoration. What’s more, it has been sold to a large number of quartz original producing countries, such as Italy, USA, Spain, Turkey, Portugal and so on. And the price of quartz is acceptable to the public.

High quality green environmental-friendly material

It is the best choice of green building, for its soft color, elegant style and inexpensive features, It can be used for kitchen countertops, dining-room, bathroom mesa, windowsill, bar, inside and outside wall, floor and etc., suitable for apartments, offices, shopping malls, hotels, subway stations, airports, hospitals, library etc.
