According to national standards, marble slabs of all grades are allowed to have certain defects, but the superior ones are not so obvious. Selecting patterns and tones: Marble slabs have a variety of colors and tones, with no identical patterns. This is precisely the charm of the precious marble slabs. The basic consistency of color tone, small color difference, and beautiful pattern are the specific manifestations of excellent varieties, otherwise it will seriously affect the decorative effect. Detecting surface glossiness: The level of glossiness on the surface of marble slabs can greatly affect the decorative effect. Generally speaking, the polished surface of high-quality marble slabs should have a mirror like luster, which can clearly reflect the scenery. However, due to the different chemical compositions of marble of different qualities, even products of the same grade will have significant differences in glossiness. The definition of quartz stone and its composition. Quartz stone is a new type of stone made by mixing 92% quartz sand powder as the main aggregate, 8% resin, pigment, and other auxiliary materials as the main bonding materials, and then vacuum pressure vibration molding, curing, and processing. It is an environmentally friendly and green new building material and decorative material that is free of radioactive pollution, reusable. Composition of Quartz Stone 1. Resin: Resin is the basic material of quartz stone, which has the functions of bonding and providing toughness. Filling material: The main component of quartz stone filling material is silica, and others include quartz stone sand, quartz stone powder, casting sand, broken glass, shells, sea sand, etc. Pigments: The function of pigments in quartz stone is to mix various colors and varieties, making it rich and colorful. Curing agent: Curing agent is an essential additive in the production of quartz stone, which can play an important role in the shaping and dense forming process of quartz stone. Other additives: Resin belongs to polymer materials, and adding some additives appropriately can improve its process, increase production efficiency, enhance the performance of quartz stone, and extend its service life. The four major systems of Zhongxun assist in the quality mixing system. The raw materials are transported by a fully automatic pipeline conveying system, and a closed mixing process combining planetary revolution and rotation principles is adopted to ensure that the raw materials are mixed more finely and evenly, fully guaranteeing the integrity of the quartz stone board.
4. The amount of water added is 16% to 18% of the weight of the repair material, which is 8-9 kilograms of water per bag of material
Construction method:
1. Before use, it is necessary to clean the loose materials and dust on the surface of the repaired concrete, and only when there is no visible water can construction be carried out.
2. When mixing, the repair material should be mixed evenly according to the water consumption provided in the instructions (i.e. 8-9 kilograms of water per bag) before pouring for construction. If the pouring area and volume are too large, a small amount of fine stones or large sand can be added to reduce concentrated exothermic reactions. Pour the mixed slurry into the area that needs to be repaired, compact and smooth it, and cover it with plastic film and water it for curing in a timely manner after the repair slurry has finally set. In winter, it is necessary to cover it with cotton felt for insulation protection.
Pickling+Brushed: First wash and then do antique processing. Sandblasted uses ordinary river sand or diamond sand instead of high-pressure water to wash the surface of stone, forming a decorative surface with a smooth sanding effect. Groove: A groove with a certain depth and width is usually made on the surface of stone. Mushroom stone is usually cut manually, with a similar effect to natural cutting, but the surface of the stone is shaped like a plateau with a central protrusion and surrounding depressions. Grinding edge chicken beak: Make a 5 * 5mm L-shaped notch on the edge of the board.
3. Road opening hours: Depending on the customer's design intensity and construction season, the fast opening hours are 2-8 hours.
Attention: This product is packaged in 50kg/bag (kraft paper composite bag)
Storage conditions: Dry environment for 12 months without affecting use
According to the theory of vibration, the excitation force is directly proportional to the square of the rotational speed of the eccentric block, and its amplitude is inversely proportional to the sum of its own weight and the applied pressure. From this, it can be seen that the heavy pressure and oil cylinder compression methods may be conceptual errors. In order to produce quartz stone with the reliability and performance of this pressing machine that still needs improvement, it is necessary to add more than 2 percentage points of resin in the molding process, which will naturally lead to problems such as material agglomeration and insufficient compactness. In fact, there is also a problem of insufficient excitation frequency in the molding of raw materials. The vibration generated by the 42r/min speed of regular equipment is very strong. Fortunately, the formation of raw materials can be compensated for by increasing the reciprocating vibration of the kneading process and adding more calcium powder to make the material more fluid.
