Description
Technical field
The utility model is related to a kind of film preparation experimental provision, and more particularly to a kind of phase inversion film preparation is filtered and de-
Steep experimental provision.
Background technology
Current polymer separation film is industrially widely used, mainly have microfiltration membranes, milipore filter, NF membrane,
Reverse osmosis membrane and gas separation membrane etc..The preparation of most polymers seperation film is all to use Immersion precipitation phase inversion method, directly
Polymer separation film product is made or separating layer is coated on this basis, composite membrane is made.This method for application extensively, can be used for
Prepare various films.Immersion precipitation phase inversion polymer separation film preparation technology dissolves a polymer in appropriate solvent or solvent mixing
In thing, the polymer solution of gained is commonly referred to as casting solution.Casting solution is directly scraped on a support with scraper, such as glass plate or poly-
Ester non-woven fabrics, during the film immersion precipitation scraped is bathed, so as to occur exchanging for solvent and non-solvent, ultimately results in polymer and coagulates
Glue, thus can be made polymer flat plate seperation film；Casting solution is extruded by spinning nozzle, into coagulation bath, occurs inversion of phases, is made
Polymer hollow fiber membrane.
In polymer film preparation process, the preparation of casting solution and treatment effect influence the separating property of film.Casting solution is prepared
During, the addition of each recipe ingredient can be brought into insoluble impurity, process for preparation also due to the limitation of mixing plant, part
Component is reunited or gel, it is impossible to be completely dispersed.Impurity, aggregate, the presence of jello can make the polymer film prepared at this
Point is discontinuous, produces defect.The casting film fluid viscosity of polymer film is higher, a large amount of gases can be mixed into whipping process, gas is with gas
The form of bubble is present, and obtained polymer film surface is had pin hole, fracture of wire is may also result in polymer hollow fiber membrane.Due to
Traditional filter volume is excessive, and the feed liquid loss brought is serious, during preparing polymer film in laboratory at present, filtering
Process is ignored mostly, and obtained polymer film is determined after screening out defect through naked eyes, has thus also had a strong impact on test result；It is de-
The usual manner of bubble uses long the time required to standing and defoaming, standing and defoaming, and is not suitable for high viscosity casting solution.
The content of the invention
In view of the above mentioned problem that prior art is present, the utility model purpose is intended to that there is provided a kind of phase inversion film system
Standby filtering and deaeration experimental provision.
