By the 16th century, glassmakers discovered how to make many different tones of glass. Therefore, some mosaic workshops produced as many as 10,000 different tones of mosaics at that time. They began to imitate painters' paintings or copy famous paintings by mosaic mosaics. Mosaic art has become highly detailed and complicated, leaving many classic mosaic art works in the world. Materials used: glass mosaic, stone mosaic, highland art (AntoniGaudi), 19th century-2nd century. However, when painting developed in the 14th century, people lacked interest in mosaics.


The waterproofing of the basement of the cold storage has been treated accordingly during construction. However, due to the low location of the basement, once there is a gap in the waterproof layer of the ground or wall of the local lower room, water will inevitably flow into the room. The water sources that invade the basement include groundwater and surface diving, and corresponding waterproof measures should be taken for different situations. In addition to the necessary waterproofing of walls and floors, a drainage system must be installed on the floor of the cold storage to reduce the penetration of surface water into the room.
Rubber and plastic products are molded and processed in the mold. The rubber and plastic materials contact the mold surface. There may be a certain frictional resistance when the rubber and plastic products are peeled from the mold due to micro-defects such as the uneven working surface of the mold.
In the process of injection or extrusion of rubber and plastics, negative pressure is often formed between the rubber and plastic materials and the mold, or the two are bonded due to physical adsorption or chemical bonding, which results in the rubber and plastic products being removed from the mold after molding. Difficult to peel. In order to weaken the adsorption or bonding between the product and the mold, an additive that can form an effective isolation film-a mold release agent is often used. The release agent is an interface film layer used on the surfaces of two objects that are easy to adhere to each other to form an isolation between the adherend and the adherend, so that it is easy to peel, making the product demold easier and more convenient. There are many types of basic materials that can be used as mold release agents. Commonly used mold release agents include inorganic, organic, and polymer types.
Commonly used inorganic release agents include graphite powder, talc powder, mica powder, molybdenum disulfide and other powders. Commonly used organic release agents include fatty acids, fatty acid soaps, various waxes, glycols, etc. Molding agent also has the function of lubricant. Polymer mold release agents mainly include polyvinyl alcohol, cellulose acetate, organic fluoropolymer and silicone polymer, etc. Among them, silicone polymer is the most suitable mold release agent

It is named after the stone with brilliant colors and patterns produced in Diancangshan, Dali, Yunnan. Marble generally refers to marble, limestone, dolomite, and skarn and marble formed by different alterations of carbonate rocks. Marble is mainly used for processing into various shapes and plates, and is used as a precious material for furniture inlays as the walls, floors, tables, and columns of buildings. It is also commonly used as materials for monumental buildings such as monuments, towers, and statues. Marble can also be carved into practical works of art, such as arts and crafts, stationery, lamps, and utensils. Marble has a soft, beautiful and solemn texture, elegant style, and a wide variety of colors. It is an ideal material for decorating luxurious buildings and a traditional material for artistic carving.


The cotton waterproofing agent also depends on which cotton waterproofing agent it is. The general cotton waterproofing agent can be used in the waterproofing treatment of cotton and chemical fiber fabrics. It depends on the waterproof effect. You can consider Zhuang Jie's cotton waterproofing agent. His cotton waterproofing agent can be used for cotton waterproofing treatment and polyester waterproofing treatment, as well as nylon waterproofing treatment. And polyester waterproof 10 grams waterproof 100 points.
Silicone release agent is made from organosiloxane as raw material. Its advantages are good heat resistance, moderate surface tension, easy to form a uniform isolation film, long release life, non-toxic, good gloss, and no affinity with resin. It is suitable and widely used in various occasions such as plastics and rubber. The disadvantage is that there is a layer of oily surface on the surface of the product after demolding, and the surface must be cleaned after secondary processing. Commonly used are silicone oil, silicone rubber, emulsified silicone oil and silicone grease. Silicone mold release agents are currently the mainstream products in the mid-range market of rubber and plastic mold release agents. They are widely used in the processing of polyurethane, rubber, polyethylene and polyvinyl chloride resins.

Dow Corning, Japan Orient Oil Industry Co., Ltd. and Shin-Etsu's silicone release agents are mainly sold abroad. There are many domestic factories producing silicone release agents, but their scale is relatively small.

Then it is numbered according to the connection sequence between the various decomposition patterns of the parquet to prevent confusion. Then use a sharp knife to cut out each pattern mold along the outer line of the pattern. Note that the top of the cutting line must be perpendicular to the horizontal line, not oblique, and the arc angle cannot be moved. The traditional method of making sub-parts is to accurately depict the shape and specifications of the mold made before on the selected stone (slate) and cut them separately. Note that there is a machining allowance reserved during cutting, about 1-2mm, which is used as a remedy for moving. However, most of the current cutting is done with waterjets, and there is no need to make templates. The required specifications, sizes, shapes, etc. are input into the waterjet numerical control equipment, and the required parquet pattern components are directly cut on the board through computer control.


The main difference between carben silane dipping coating paste and liquid is that the properties of the two are different. 1. The effective ingredients are different: the active ingredient of the paste is iso-octyl triethoxy silane, and the liquid is isobutyl triethoxy silane. 2. Different dosage: 200-300g/㎡ for paste and 600g/㎡ for liquid. 3. Different colors: the paste is white, and the liquid is colorless and transparent. Choose silane dipping coating paste or liquid according to the specific situation of the project.
