Abstract
The present invention discloses a method for making a polyvinyl chloride calendered film for a blood transfusion appliance. A granular or powdery polyvinyl chloride material is added into a high speed mixing machine to be kneaded at a high sped by the method, and then, the granular or powdery polyvinyl chloride material is sent into an extrusion machine to be plasticized, and is uniformly extruded. An extruded material is calendered and formed by a calender after glue refining and filtration to obtain a film. Both surfaces of the film which is peeled and released by the calender are embossed. The film is slitted and packed according to specifications after cooling treatment, destaticizing, dust suction and cleaning treatment. The inventor sums up the making method for producing a polyvinyl chloride calendered film for a blood transfusion appliance by researching each calendering process, and a blood bag which is made of the film obtained by processing conforms to the national standard. Therefore, the film which is made by the present invention has the characteristics of uniform thickness, good strength, double-surface patterns and unidirectional air permeability. The blood bag which is made of the film has the advantages of flat inner and outer surfaces, transparent and uniform thermal sealing lines, and no adhesion. The film can completely substitute for a film for an imported blood transfusion bag.
Description
Technical field:
The present invention relates to a kind of preparation method of calendered film of polyvinyl chloride for blood transfusion appliance, belong to the plastic sheeting manufacture technology field.
Background technology:
The multi-joint bag of the existing blood sampling of China adds alserver's solution by the ACD-B anti-coagulants and adds the blood plasma collecting bag and forms, and blood sampling is after the refrigeration storage.The blood bag needs to carry out the cell separation chromatography through 3500RPM centrifugal speed 10 minutes at temperature 4-5 degree before use.Along with growing with each passing day of the blood used in clinic amount of China, the consumption of blood bag is very huge.But be subjected to the manufacture craft influence of existing blood transfusion utensil with film, the blood bag of making exists problem such as easy breakage and erythrocyte damage when centrifugal, and therefore the waste that causes is also very huge.In the prior art, the film production process of blood bag still adopts the blow molding process of the seventies and eighties, the became uneven of the film of producing, big to the hot strength difference in length and breadth, cause the blood bag made damaged easily in centrifugal process, and on this film, can only make the vertical bar decorative pattern of single face, and the blood bag is when heating disinfection, and the film of shiny surface is sticked together easily.And the decorative pattern lines that processes is thick, and the damage that this causes erythrocyte when centrifugal has easily had a strong impact on the quality and the storage time of blood bag storage of blood.
Summary of the invention:
The objective of the invention is to: provide a kind of film thickness of processing even, intensity is good, has the preparation method of the calendered film of polyvinyl chloride for blood transfusion appliance of two-sided decorative pattern, to overcome the deficiencies in the prior art.
The present invention is achieved in that graininess or powdery pvc material is added the kneading of high-speed mixer high speed, send in the extruder then and plastify, extrude uniformly, after the material of extruding is refined glue, filters, by the calender calendering formation, obtain film; Calender is peeled off the film that escapes carry out two-sided embossed, through cooling processing, and destatic, after the dust suction, cleaning, film cut packing by specification.
