Description
Technical field
The present invention relates to a kind of blood taking tube polyester slice, more particularly to a kind of blood taking tube polyester slice master batch, preparation
Method and application.
Background technology
Polyester is with polyethylene terephthalate（PET）The general name of the thermoplastic novolac's saturated polyester to represent, it
An important use be for food packaging applications.Both biaxial tension packaging film had been can be made into as PET during packaging material for food,
It is blow molded the stretch blow bottle that high intensity, high transparency is obtained after can be made into amorphous state bottle base again again, piece can also be directly extruded into
After material, thermoforming is obtained hollow container again.PET products have transparent, oil resistant, protect fragrant, health reliability and use wide temperature range etc.
Performance, therefore the consumption in packaging field constantly increases.
Application of the polyester (PET) in Medical Equipment and packaging industry and growth cause the extensive concern of people.Polyester
(PET) it is that cost is relatively low to be compared to the feature of glass and metal material in medical application, and uses plastic processing system
The product made usually is directly processed, and there is no need sterilization reuse；Plastics can be molded as various useful knot
Structure, and metal and glass are difficult to manufacture the product of labyrinth；Plastics are also broken not as glass, but also hard and be rich in bullet
Property；Plastics usually show certain chemical inertness, mithridatism and disinfectant.Polyester in recent years（PET）In the medical field
To being widely applied.
Compared with ordinary plastic articles, medical device has the features such as complex structure, wall thickness are less, size difference is larger, and one
As wall thickness be less than 1mm when be referred to as thin-gage goods.More accurately then grow than size to define thin-gage goods with stream, i.e., from the main flow of mould
Road to farthest flow process L of any of finished product, divided by the wall thickness t of finished product, referred to as flow process/wall ratio.It is as L/t ＞ 150, referred to as thin
Wall.With the lighting of product, relevant plastic components design just more and more thinner.Thin-walled property is because with reduction product weight and profile
Size, become plastics consumption industry the advantages of be easy to Integrated design and assembling, shorten the production cycle, save material and reduces cost
The target of pursuit, it has also become new study hotspot in plastic shaping industry.The design philosophy and method of technique thin-gage goods is more
Complexity, and further selected to be affected by molding limitation and material.Thin-gage goods requires there is high impact strength, good
Good presentation quality and dimensional stability, and big static load can be born, the mobility of moulding material will be got well.In design process
Emphasis is wanted to consider the rigid of product, impact resistance and manufacturability.
Polyester（PET）Melt shows as the characteristic of non-Newtonian fluid, i.e., the characteristics of melt has shear shinning, that is, with
The increase of shear rate, the viscosity of melt will be reduced, viscosity reduce contribute to flowing of the plastic melt in mold cavity and
Filling.Melt viscosity in barrel is higher, and flowing velocity is also little, after reaching cast gate, due to the contraction of cast gate so that melt
Flowing velocity increases, and increases shear rate, reduces the viscosity of melt, is conducive to the mold filling of melt.By increasing melt temperature
Degree and injection pressure can improve polyester（PET）The mobility of melt, but for thin-gage goods, common polyester（PET）Material
The needs of its fluidity of molten can not have been met by adjusting the temperature and pressure of processing.
