How the choose and buy breaks fittings of hardware of window of bridge aluminous door

Use the material with close of aluminous profile voltage or use be able to bear or endure the stuff with corrode better sex is one of optimal choices, if employ aluminium alloy,make hold hand, hinge reachs all sorts of join. This kind is combined with the metal is to avoid generation from occasionally the good design of batteries. But as a result of,also have a lot of parts intensity or the reason of the difficulty that make, employ aluminium and aluminium alloy not easily, so be able to bear or endure the stainless steel with corrode better sex also should be one of first selection material. Stainless steel has antirust effect commonly, the Cr in wanting steel only is more than 12. But contain Cr only in steel the stainless steel of a kind of single element, its are able to bear or endure corrode function not very good, rust easily also. Titanium is contained in steel only, make carbide not random, just have taller fight erode function, be like 1Crl8Ni9Ti. Be able to bear or endure the stainless steel with corrode good sex is commonly the composition such as chromic, nickel, titanium is contained to form in steel, its itself is a complex galvanic cell structure, chemistry is not so random the gender is good. In the solution of a lot of acid, alkaline, salt, be able to bear or endure in organic acid, vapour and moist air aggressivity is tall, use stainless steel to be able to decrease or avoid profile to produce the harm sex that couple erodes.

Breaking fittings of hardware of window of bridge aluminous door is his important composition branch, its function and put to good use of function of window of quality face each other have main effect. Because of the ceaseless development of modern technology, fittings of door window hardware (shake handshandle, armrest, hinge, slippery course, join wait) , swarm into the market increasingly also. The appearance of these products and color, multifarious, full of beautiful things in eyes, make of door window practical grace with the exterior many. But what decorate a material because of hardware data and surface is different, their service life (basically point to be able to bear or endure aggressivity, wear and intensity) differ very far, although glorious is identical, even its difference can amount to the fittings of aluminium alloy window with similar also feel multiple and even number is decuple. Hardware of window of door of the aluminium that break the bridge need besides the consideration after having the mechanical strength with enough stock, when the material that chooses alertly even and aluminium alloy contact are used, whether keep better be able to bear or endure corrode sex. Hardware of window of door of the aluminium that break the bridge whether achieve design life requirement, the security in using a process to breaking window of bridge aluminous door, wear is very important, only true put to good use breaks both union good ability window of bridge aluminous door is beautiful the characteristic of easy, wear well.

Steeliness and aluminium make hardware the surface is in air very oxidize easily. Former meeting is inherent a structure is inattentive ferruginous, this ferruginous not only humiliating, and air still can pass through this the layer is ferruginous and successive with the matrix below rolled steel happening carries change, till whole board is full,become ferruginous till. Aluminous material surface is met inherent an oxidation film that shows hoar slightly. The oxidation film of surface of admittedly aluminous material is more compact, can prevent the aluminous matrix below basically to carry further change, but its are original the burnish of silvery white suffers more austere destruction however. To prevent above the happening of two kinds of phenomena, defend besides plating outside decorating a layer, the hardware that also can making newly the surface makes film of an artificial oxidation artificially.

Using new technology, new technology, new data is fittings of hardware of ascensive door window be able to bear or endure the only way of aggressivity. Foreign hardware produces business uses plating of physical gas phase (abbreviation PVD, also call vacuum plating) produce the hardware fittings with an exterior and admirable anti-corrosive properties. Vacuum plating has adherent power strong, film falls off not easily; Diffraction sex is good, film ply is average; Film is compact, bleb of needle lonely L is little; The manageability before plating, craft is austere; With makings province, wait for good qualities without social effects of pollution. Can be in metal or metalloid apparently plating makes simple substance, alloy or compound. The preparation in ever was being used extensively at the industrial share such as aviation, space navigation, electron and optics all sorts of special functionary film. Those who follow vacuum plating equipment is ceaseless and perfect, large change and change continuously, and the development of technology of coating besmear outfit, can obtain a written guarantee cooperative strong, brightness decorates good, wearability high sexual film. Abroad is in hold the surface of a few fittings such as hand, hinge, use vacuum plating Au, Ag, Al, Zr, TiN, LCrl8Ni9 to wait, and gain the outside face with integrated admirable function, make hold fittings of these single function sex such as hand, hinge are become have use function and adornment double functionary fittings.

The data that in breaking fittings of hardware of window of bridge aluminous door at present, uses in great quantities is carbolic steel, if transmission lock is shut implement, line steel. To carbolic steel character, erodent main reason is galvanization layer ply insufficient. To carbolic steel plating should ask to increase galvanization layer ply, still should strengthen aftertreatment craft at the same time, be like silicate with inorganic salt kind or organic film undertakes basket lid is handled, of layers of such galvanization of can great progress be able to bear or endure aggressivity, via the Yuan Caihong after block lubricious passivation film makes golden scene.
