With polypropylene and polyethylene phthalein amine raw material to produce extrusionBlown film machineBlown film, request the transparency of film is higher, with cooling water quench ring effect is very good.Blowing bubble tube outer diameter and the ring diameter of cooling water, water ring inside the cooling water, cooling water to overflow from the jacketed tube along the bubble.This way of cooling is ideal.Membrane attached to the water drops, after bag cloth guide roller is absorbed.In addition, PVC calendering method is the main film forming process.Rolling process while the large investment, high technical requirements of equipment maintenance and operation is complicated, but it is production advantages of quick speed, good quality of the production of thin film, compared with the similar equipment, has a higher yield, plasticizing good products, low energy consumption, the advantages of simple operation, completely solve the film falbala and winding size top problem, can produce 70 - a - 350 um all kinds of PVC film, the thickness of the slice.Fully embodies its advantage of energy saving, save a large amount of electricity cost for plastic processing enterprises, improve the production efficiency, improve the workshop environment, thereby directly reduce the indirect costs of production.

Manufacturing machinery technology innovation will promote the development of plastic industry, for a long time, plastic industry depends on foreign advanced mechanical equipment, the introduction of foreign technology, will improve the plastic industry and machinery for the production cost, developing intelligent molding machine model not only improves the performance of blown film machine, can reduce cost, reduced working hours, will significantly improve the plastic industry status quo.Push the process due to the plastic screw and plastic and the friction between machine barrel and particle collisions between friction, also due to the external heating of cylinder melted the plastic.Molten plastic by the head of the filtered to remove impurities from the mold, after cooling, blowing, etc will be finished film rolled into a cylinder.Single draught cooling air ring.The structure of single draught cooling air ring.The wind ring consists of two parts, with combination of threaded connection.Sent of cold air blower, the three air inlet along the tangent direction in the wind ring coat the wind ring, after a couple of adjustable clearance wind ring control, make the air flow is stable to blow out and along the bubble tube outer diameter, thereby cooling bubble tube film cooling curing.

Three-tier co-extrusion blown film machine from the domestic market, molding machine production value of 18.873 billion yuan in 2010, the growth rate of 18%, extrusion machine product for up to 18, 254.Extruder class output value of 3.87 billion yuan.The high grade, high performance of blown film machine accounts for only about 1% of the total share.Can produce high performance film blown film machine.Nylon membrane such as high-performance barrier membrane, high performance, high performance of the medical membrane and constriction of the high-performance composite membrane, etc.Five layers co-extrusion blown film line, mainly is suitable for the HDPE, MHDPE, LDPE, LLDPE, MLLDPE, PA, EVOH resin with gases trap, the production of thin film is mainly used for packaging, high-grade food bag, vacuum bag, liquid packaging bags and other packaging materials, incense, fresh, anti-corrosion, airtight, extend the shelf life of the packing.Make the product quality on a new step.This film because of its good barrier property, keeping fresh, well protected against dampness, frost proof, oxygen insulation, oil resistant, can be widely used for packing weight.Dalian friend rock plastic machinery co., LTD., specializing in the productionDouble blow film machineMonolayer film blowing machine, a single layer, three-tier co-extrusion blown film machine, blown film machine.Responsible for the safety debugging, training operators, if you are interested in our company, you can visit our website:www.dlyouyan.com
