Author: asphalt mixing plant URLs /xiazai/fhi.htm Published: 2012-11-13 Asphalt mixing should be based on the requirements of the road construction, project size and construction period to determine the production capacity of mixing equipment. Choosing the right model must also consider the ability to match friends' work. The product selection first determines the productivity (productivity is replaced by Q) and the following formula is derived: Q=SHR/NKT S = paving area (m2) H = floor thickness (m) N = planned construction time (days) R = compacted density, take 2.4t/m3; T = more than ten working hours per day, take 10h (hours); K=construction day coefficient (considering only rain and maintenance time regardless of holidays) K=number of possible working days/number of planned calendar days during the construction period, Generally, the productivity Q calculated from the above formula by taking K=0.8 h is the required production capacity of the asphalt mixing equipment. The actual choice of equipment must meet and exceed this productivity in order to meet normal construction requirements.
Place the meat on special trays, plate paper or film for skin packaging, a three-dimensional packaging effect is formed, which improves the shelf level and achieves the purpose of oxygen insulation, freshness, moisture, poison, rust, corrosion, pollution, etc., which is effective Extended shelf life is convenient for storage and transportation.
The skinned vacuum packaging machine is a new type of product packaging technology. The skinned packaging can extend the shelf life of the product, have a strong three-dimensional view, and is not easy to pack. It can be widely used in hardware tools, auto parts, medical equipment, electrical and electronic components, and toys. , Stationery, knives, tableware and crafts, etc. Especially suitable for packaging of various seafood such as sea cucumber, abalone, lobster, etc.
The skin packaging is formed by vacuum suction according to the shape of the product and pasted on the cardboard (or bubble cloth, etc.). The transparent skin film is heated and softened and then covered on the product.
The vacuum pump of this equipment adopts the BUSCH100 vacuum pump imported from Germany from Puxu Company. The frame is made of stainless steel. The upper cover is made of 6mm thick 304 stainless steel, and the lower cover is made of integral cast aluminum alloy. The air cylinder uses Airtac thin cylinders, the electrical appliances use Siemens or Schneider AC contactors, Delta microcomputer control, Delta interface display adjustment, German Turck non-contact induction switch, Airtac pneumatic components.
