Further, in the above-mentioned technical solutions, supercritical carbon dioxide extracting polyvinyl surface Spin Finish System, carbon dioxide
Horizontal extraction kettle is reached by carbon dioxide booster pump and preheater, is separated after the reaction was completed by the second-order separation kettle, most
Carbon dioxide returns to carbon dioxide storage tank therewith afterwards.
Decompression separates finish with carbon dioxide gas after extraction, takes out extraction sample, and sample is dry without cleaning
Dry equal post-processing.Extraction yield mainly passes through extraction time, extraction temperature, extracting pressure, the variation of the factors such as carbon dioxide flow rate
To control.Wherein, the metering of the supercritical carbon dioxide fluid flow velocity is the supercriticality dioxy to flow through per minute
The quality for changing carbon is standard.
The extraction temperature in the kettle is 80-110 DEG C as a preferred technical solution,.

Beneficial effects of the present invention：The present invention provides a kind of new supercritical carbon dioxide extracting polyvinyl surface finish system
System, which is equipped with CO 2 fluid entrance using horizontal extraction kettle, in the bottom of autoclave body, and top is equipped with outlet,
Bottom silicon dioxide carbon flow body flows into autoclave body when extraction, impacts polyvinyl and carries out extraction surface finish, the system in a manner of non-static
Using the second-order separation kettle, in kettle, pressure is available shares, to improve extraction yield.It can also be by controlling supercritical carbon dioxide
The flow velocity of fluid realizes the variation of air-flow, so that polyvinyl be made to move under the gear shift shock of air-flow, avoids polyvinyl weight
The extraction at folded place stops.Using extraction process of the invention, the polyvinyl used for subsequent dyeing can be obtained, it is extracted
Product does not need the post-processing such as to be cleaned, dried, and realizes the anhydrous removal polyvinyl surface finish of overall process, saves production cost,
It improves and removes oil quality, reduce environmental pollution.
