Abstract
A PVC electrolyzer used in electrochemical test is prepared for opening round hole with thread at bottom surface of top cover and opening round hole with thread at top surface of bottom cover as well as opening holes at top surface of top cover, arranging thread mating with threads on top and bottom covers at two ends of cylinder, connecting top and bottom covers with middle cylinder by threads.
Description
Technical field
The present invention relates to electro-chemical test and analyze support equipment, particularly relate to a kind of electrolytic cell in use for electrochemical tests.
Background technology
Electrolytic cell is all used in existing electro-chemical test sheet metal corrosion or the corrosion of plate surface rete.As electrolytic cell Tail Cell K0307 and K0302 that U.S. Princeton Applied Research company produces, this all has introduction in the product manual of www.par-online.com and www.perkinelmer.com website; ZL00214803.X also discloses a kind of electrolytic cell.This class cell operation electrode all is to be placed between the lower nozzle of bottom hardboard and sleeve pipe, when changing sample, all disassemble whole devices, and be difficult to control, and the making of sample and placement are also very time-consuming; In addition, this class electrolytic cell is all by placing working electrode part, salt bridge portion, holding the electrolytic solution part and the placement working electrode is partly formed, connection between the each several part generally all adopts iron and steel parts to fix, as screw, screw rod etc., because electrolytic solution has corrosion to iron and steel parts, thereby damage, influence the serviceable life of electrolytic cell; Also have, this class electrolytic cell in use for electrochemical tests is in test process, and tested sheet coupon all is a mono-sheet, and every survey one less important dismounting once, and is very time-consuming; When analyzing the corrosion of sheet material superficial film continuous position, carry out a large amount of monolithic test jobs, and the monolithic sample because scratching and position problems, shear makes test can not reflect the decay resistance of whole rete fully.
Summary of the invention
Technical matters to be solved by this invention provides a kind of electrolytic cell in use for electrochemical tests, this electrolytic cell convenient disassembly.
The technical scheme that technical solution problem of the present invention is adopted is: electrolytic cell in use for electrochemical tests, cylinder by upper cover plate, lower cover, both end thread is formed, lower surface at upper cover plate has threaded circular hole, upper surface at lower cover has threaded circular hole, upper surface at upper cover plate has hole and hole, the screw thread of upper cover plate, lower cover and the screw thread of cylinder are complementary, upper cover plate, lower cover and middle cylinder are fitted together by thread set, laterally have through hole at the sidewall of described lower cover.
The invention has the beneficial effects as follows: the present invention dismantles simply, only needs that the cylinder screw thread is loosened several roads and gets final product, and is simple to operate; The present invention all adopts the PVC member to form, and has avoided irony screw and screw rod to get rusty in the salt environment in use, and prolong serviceable life greatly; It is that two directions connect that the present invention places the working electrode position, the working electrode sample can be made into rectangular sample, is placed on the electrolytic cell below, tests successively along the band sample direction, when analyzing the corrosion of sheet material superficial film continuous position, test result can reflect the decay resistance of whole rete.

Embodiment
The present invention is made up of the cylinder 7 of upper cover plate 8, lower cover 9, both end thread.Lower surface at upper cover plate 8 has threaded circular hole 3, has first hole 1 and 2, the first holes 1, second hole and first hole 2 at the upper surface of upper cover plate 8 and preferably is set to strip hole 1 and circular hole 2 respectively, places auxiliary electrode and contrast electrode respectively.Sidewall at lower cover 9 laterally has through hole 5, be used for placing the sheet coupon 10 (working electrode) that to test, upper surface at lower cover 9 has threaded circular hole 4, the screw thread of the screw thread of upper cover plate 8, lower cover 9 and cylinder 7 is complementary, and upper cover plate 8, lower cover 9 and middle cylinder 7 are tightened by screw thread and fitted together.
The material of upper cover plate 8, lower cover 9 and cylinder 7 all adopts the PVC material to make, and also is provided with packing washer 6 in cylinder 7 bottoms, is used for preventing that electrolytic solution from flowing out, the influence test.
During test, earlier sheet coupon 10 to be measured is passed the through hole 5 on the lower cover 9, then, PVC cylinder 7 lower ends that will have O-ring seal 6 are screwed into threaded circular hole 4 places on the lower cover 9, and cylinder 7 bottoms are closely contacted with sample 10 on the lower cover 9, then, again threaded circular hole 3 places on the upper cover plate 8 and PVC cylinder 7 upper ends are tightened, in cylinder 7, pour electrolyte solution into again, insert auxiliary electrode at strip hole 1 place, circular hole 2 places insert contrast electrode, turn on the electricity and just can carry out electro-chemical test.
