ジャーナル フリーSince, according to the previous works, though it depends on the nature of aluminium alloys, the effect of alcohol-phosphate treatment prior to enameling is generally recognized, this time the special primer containing phosphoric acid which is etch type is investigated successively. The surface proparations by chemical treatments of aluminium alloys are not needed at all in the case of “Etch-priming”, hence the specimens are primed first and then coated with zinc chromate phthalic resin enamel. And bending-test, drawing-test, erichsen-test and corrosion-tsst are performed. The one of the vehicles used to “Etch-primer” is based on poly-vinylacetate and the other one on copolymers of vinyl acetate and methyl metacrylate in the works. The results of these tests are useful for comparative evalution. In short, in the vehicle based on poly-vinylacetate etch-priming coats are effec tive even in phospholic acid addition of only 0.8%, but in that based on co-polymers of vinyl acetate and methyl metacrylate not yet effective.抄録全体を表示PDF形式でダウンロード (450K) -

ジャーナル フリーIn the etch-type primer of aluminium alloys phosphoric acid is usually used as the active component, for the effective surface is prepared easily by phosphoric acid, which attacks to aluminium alloys, especially in Mg-Al alloys.
The previous works (report III) were comparative investigations on two vehicles based on polyvinylacetate and on co-polymers of vinylacetate and methyl-metacrylate in phosphoric acid addition of 0.6 %, 0.8% or 1.0%. And it was recognized for the etch-priming based on polyvinylacetate to be more suitable than the latter. Hereupon, it is discussed on the effect of increased phosphoric acid and water on the special priming based on polyvinylacetate vehicle in this report. Namely, in order that the special primers, containing the various amounts of phosphoric acid or wather, are investigated the each specimen (52 S), which is primed with them and then coated with zinc chromate phthalic resin enamel, is offered to drawing-test or erichsen-test in the same way as previously.抄録全体を表示PDF形式でダウンロード (1137K) -

ジャーナル フリーThe device is described which permits accurrate measurement of the thickness of electrodeposited metal coatings, based upon the principle that the current-time product required for the anodic dissolution of a given small area of the plated metals are directly proportional to the thickness of the plating. The kinds of coatings measured successfully include: chromium, nickel, cupper and zinc with an accuracy of 5 to 10 percent.抄録全体を表示PDF形式でダウンロード (891K) -

ジャーナル フリーWe devised a comparatively simple super-finishing apparatus to be attached to an ordinary lathe. This apparatus was designed so as to ce used even by a student who is not familiar with such works. We examined the conventional relations among the hardness of sumple piece (quenched steel), kind of grind-stone, the revolutional velocity of the piece, number of vibrations and the amplitude of grindstone, pressure at the grind surface, and the quality of the cutting fluids. The similar experiments were carried out for brass and alluminium. It was found, by these experiments, that, for quenched steel, we can get a mirror-like surface with the roughness of about 0.2S (JES) and that with our simple apparatus, super-finishing of this order may be accomplished even by an unexperienced worker. But for brass and alluminium, it was not yet succeeded to get the mirror-like surface, though a comparativeley smooth surfaces were obtained. This method of super-finishing was also put in use as trial, with successful result, in the small work shops in our vicinity. Even with smoothness of this order, the life of plug ganges may be prolonged 5 to 6 times and for the other machine parts it is proved to be quite good for anti-friction, prevention of stain and improvement of efficiency or ability.抄録全体を表示PDF形式でダウンロード (1372K) -

ジャーナル フリーThree component system were prepared containing varing percentages of melamine-formaldehyde resin, phtharic acid glycerine ester and n-butanol, and examined the foundamental properties for pains.
From the results it has became clear that the optimum composition which was adapted for paints was 20-80% phtharic acid glycerin ester, 20-10% melamine-formaldehyde resin, 60-10% n-butanol.抄録全体を表示PDF形式でダウンロード (555K) -
