Brief introduction of Dalian film blowing machine.



  Film blowing machine in production must be careful operation, it is strictly prohibited to membrane bubble bag around the traction roller and traction rollers. When the film is cut, not knives on the guide roller surface cutting, to scratch the surface of the roller, affecting the appearance of film. When the equipment, environment, product thickness and uniformity to meet the requirements, or the test with the requirements, meet the above requirements and inspection, as the finished product production. Dalian film blowing unit in order to meet the production process of plastic film packaging material some special functional needs, various material properties of blown film and co extruded together to form multifunctional plastic film, the development of the three layer coextrusion film blowing machine.


  Film blowing machine, dry polyethylene particles into the hopper in, by the weight of the particle itself from the hopper into the screw, when the pellets and screw thread oblique edge contact, the rotation of the oblique edge face plastic and slant edge perpendicular to the surface of the thrust, the plastic particles goes forward, progresses, the plastic melt the filter head to impurities from the mouth of the die, the wind ring cooling, blown the lambdoidal board, traction roll, roll the finished film is coiled into a cylinder. The air ring device is mainly composed of a blower, an air volume distributor, a wind loop and a wind pipe, and the air flow distributor is blown by a blower to enter the air loop through the air pipe to form a bubble, and the purpose of cooling is realized.


  Although plastic bags for recycling but are generally bag in the process of the waste bag and usually sense of waste plastics still have big difference. Film blowing machine production is suitable for all kinds of high-grade packaging film. The unique characteristics of various levels of HDPE are the appropriate combination of four basic variables: density, molecular weight, molecular weight distribution, and additive. Different catalysts are used for the production of customized special performance polymers. High density polyethylene is non-toxic, tasteless, no smell of white particles, melting point of about 130 degrees Celsius, the relative density of 0.941~0.960. So, need to add antioxidants and ultraviolet absorbent resin to improve this deficiency. High density polyethylene film in the case of the thermal deformation temperature is low, which should be paid attention to this point.
