MEANS FOR IMPREGNATING ARTICLES WITH SYNTHETICRESINS Filed Nov. 21, 1925 Patented Sept. 24, 1929 UNITED STATES PATENT UFFICE'.
MEANS FOR IMPREGNATING ARTICLES WITH SYNTHETIC RESINS Application filed November 21, 1925, Serial No. 70,671, and in France and Great Britain October 27, 1925.
The present invention relates to improvements in the means for impregnating articles with synthetic resins described in my copending application filed herewith.
The said means provided in particular the use of a stove capable of being heated and cooled at will. This arrangement permitted of obtaining in this stove, suitable temperatures for the various physico-chemical changes of the resins incorporated in the parts under treatment.
The present improvements have for object arrangements permitting of obtaining the same procedure of physico-chemical action without necessity of cooling the stove.
For this purpose the installation comprises a first stove adapted for the low temperature operations (impregnation, evaporation of the solvents when necessary) and a second stovecalled baking or polymerizing stove destined for the operations at higher.temperatures (drying of the parts before impregnation, polymerization of the resin incorporated after impregnation).
By reason of this separation, the film of Varnish or of resin which covers the walls of the stove serving for impregnation, is not changed by the high temperature operations inasmuch as it is never heated sufficiently to become insoluble and can thus be dissolved in the liquid which fills the stove at the following impregnating operation.
On the other hand the separating of the operations in two distinct apparatus permits of arranging these in such a manner that the exact process can be observed of the different physico-chemical operations drying, impregnation, evaporation of the solvents, initial transformation of the resin, second transformation thereof or polymerization.
The installation also comprises the other features of the co-pending application referred to viz:
An apparatus capable of producing vacuum or pressure and the arrangement of piping permitting of both uses; an oil freeing device for the air; a condenser for recuperating the volatile products and an arrangement permitting of evacuating the condensed products without disturbing the vacuum which may be reigning in the different apparatus.
In order that the invention may be clearly understood it has been shown by way of example in the accompanying drawing which illustrates the principle diagrammatically and wherein:
The installation comprises a stove 1 heated by suitable means connected by piping 2 having a cock 3 to a vessel 4 containing the liquid resin or the varnish of the synthetic resin:
A second stove 5 likewise suitably heated called thebaking or polymerizing stove and serving for those operations which call for the higher temperatures.
A compressor vacuum pump 6 can provide the vacuum or pressure within either stove 1 or 5 to which it is connected by suction piping 7 and exhaust piping 8. The pipings 7 and 8 are at one point connected together to form a single pipe 10 which is provided with a branch to either stove and with cocks 11, 12 to cut-01f the one or other of the stoves or both together.
An arrangement of combined piping such as described in my co-pending main application above referred to may be provided to obtain the vacuum or pressure in one or other stove 1 or 5 as required.
On the suction piping is disposed a condenser 13 which may be provided with a recuperating device for the condensed products; on the exhaust piping is arranged a device for freeing the air from oil, 14, of any known type.
The parts to be treated are first placed in the stove 5-where they are dried at about 100 degrees C. and preferably in a vacuum.
After drying the parts are immediately placed in the other stove 1 where the vacuum is next produced in order to extract the air which may have got into the parts during their transport from stove 5 to stove 1.
The cock 3 is opened and the liquid contained in the vessel 4 rises in the stove 1 under the effect of the vacuum therein. Then the cock 3 is closed.
The stove 1 is not heated during impregnation. Its dimensions are such that the tem perature finally of the liquid does not exceed The liquid flows out from the impregnated parts and returns to the vessel 4 in which likewise condense the products of evaporation.
When this operation is terminated the articles are taken to thepolymerizing or baking stove 5. This stove is heated progressively up to a suitable temperature for the treat- I ment of the synthetic resin employed.
The polymerization may take place under air pressure or pressure of any other fluid or at atmospheric pressure and it may even be followed in some instances by a vacuum treatment.
