Vermiculite board is a new type of building materials, is made of expanded vermiculite and a certain dose of adhesive through hot pressing or cold pressing molding, it is also called expanded vermiculite board, with high strength and toughness, with heat preservation, heat insulation, fire prevention and other advantages. More used for fire door core, fireplace lining, wall materials, etc. Four-beam and four-column hydraulic presses, also known as vermiculite hydraulic presses, are commonly used in the production of vermiculite slabs, including 400 tons, 500 tons, 630 tons, 800 tons, 1000 tons, etc.
vermiculite board hydraulic machine production process:
1. Preparation of raw materials: high-quality vermiculite, expansion agent, binder and other raw materials are selected and mixed according to a certain proportion to make a uniform mixture.
2. Press forming: Put the mixture into the press for press forming. When pressing, the pressure of the press and the size of the mold should be adjusted according to the thickness and size of the plate. In general, the pressed plate needs to be shaped to ensure that the size and shape of the plate are stable.
3. Drying: Put the molded thermal insulation vermiculite board into an oven for drying. The drying temperature and time will depend on the type of binder and vermiculite selected. After drying, the moisture content of the board will be reduced to a certain extent.
4. Cutting and packaging: cut the dried heat preservation vermiculite board and make various sizes of boards as required. After cutting, the sheets need to be packaged to prevent the attachment of dust and other contaminants.
Production of vermiculite plate hydraulic press equipment -400 tons 630 tonsfour-column hydraulic pressThere are many manufacturers, on the production and manufacturing experience, on the quality of the machine equipment, on the manufacturer's after-sales service, ShandongZhongyou Heavy IndustryMachine tool companies are more recommended. The 400-ton 630-ton vermiculite board hydraulic press adopts a four-beam and four-column structure with accurate positioning, no deviation and mold damage, high product yield and neat and beautiful appearance. The model is complete, with tonnage ranging from 1200 tons to 300 tons, which can meet the output requirements of different customers. Using PLC programmable controller, automatic pressing and ejection can be realized, thus reducing labor intensity and improving production efficiency. Using unique double-sided pressure production technology, each brick has the same upper and lower pressure and uniform strength. The equipment can set the exhaust time without cracks and cracks, and can set different exhaust times according to different raw materials. A vermiculite board hydraulic press can produce vermiculite refractory boards of various specifications, only need to change the mold, can also produce different specifications of vermiculite insulation board equipment.
Among the many manufacturers of vermiculite board hydraulic press equipment -400 tons 630 tons four-column hydraulic press, they can choose the manufacturers that they are satisfied with and feel at ease. Therefore, when choosing for manufacturers, we can consider these aspects. One aspect is whether the manufacturer is formal or not. Generally, when choosing, it is better to choose a formal manufacturer. Such manufacturers can provide relevant after-sales protection. The second aspect is how about the vermiculite board hydraulic press equipment sold by this manufacturer -400 tons 630 tons four-column hydraulic press, from performance to quality, and whether the sales price can provide customers with cost-effective equipment, which is worth paying attention.
Many enterprises, in the face of many vermiculite hydraulic press manufacturers on the market, do not know how to choose, if once the choice is wrong, it will lead to their own purchase of suitable equipment. Therefore, when understanding these manufacturers, we must have a comprehensive understanding. Only after such understanding can we find the right manufacturers.
