Description
Technical field
The present invention relates to casting films production technical field more particularly to the membrane curtain coating manufacturing devices of degradable medical glue
And its manufacturing method.
Background technology
Polypropylene (PP) polymer highly crystalline for nontoxic, odorless, tasteless milky, density only have 0.90-0.91g/
Cm3 is one of kind most light in current all plastics.It is particularly stable to water, and water absorption rate in water is only 0.01%.Into
Type is good, but because shrinking percentage is big (for 1%-2.5%), thick-walled product is easily recessed, and to some high-precision parts, is difficult to
Reach requirement, product surface good luster.Polyacrylic crystallinity is high, compound with regular structure, thus with excellent mechanical property.Poly- third
The absolute value of alkene mechanical property is higher than polyethylene, but still falls within relatively low kind in a plastic material, and tensile strength is only reachable
To 30MPa or slightly higher level.
Polyethylene (polyethylene, abbreviation PE) is the aggregated thermoplastic resin obtained of ethylene.Industrially, it also wraps
Include the copolymer of ethylene and a small amount of alpha-olefin.Polyethylene is odorless, nontoxic, feel ceraceous, (minimum with excellent resistance to low temperature
Reachable -100-70 DEG C of temperature in use), chemical stability is good, is resistant to the erosion of most of soda acids (intolerant to oxidizing property
Acid).Insoluble in common solvent under room temperature, water imbibition is small, and electrical insulating property is excellent.Polyethylene has excellent chemical stability, room temperature
The various chemicals attacks such as lower resistance to hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amine, sodium hydroxide, potassium hydroxide, but nitric acid and sulphur
Acid has polyethylene stronger destruction.
To reduce pollution of the medical adhesive tape to environment, medical adhesive tape used is degradable at this stage, and adhesive tape film energy
The component for enough playing degradable function is calcium carbonate, and internal institute's proportioning calciferous is more stringent, therefore, is produced to reduce
Cost, rim charge reuse use in the case of being not more than 1/9 with virgin material mass ratio with rim charge, so that it is guaranteed that the premise of curtain coating film quality
Decline, reduce the generation of production rubbish, reduce production cost；And reuse of the prior art for rim charge, pass through virgin material and rim charge
Mass ratio, after weighing respectively to rim charge and virgin material, then the two carried out, and rim charge is due to for membrane structure, being easy to
Floating, causes both to need to take a significant amount of time in mixed process to be stirred, therefore its production efficiency is low, and matches
It is more coarse.
Invention content
The purpose of the present invention is in view of the deficiencies of the prior art, provide degradable medical glue membrane curtain coating manufacture
Device and its manufacturing method are set by the drive connection of transfer portion and subsection part, quantitatively divided while being transmitted to rim charge
