Description
【技術分野】
【０００１】
本発明は、チタン表面をクリーニングするクリーニング剤およびチタンファサードおよびパネル等のチタン表面をクリーニングする手順におけるその利用に関する。
【背景技術】
【０００２】
チタンおよびその合金の腐食に対する優れた耐性は酸化物の保護膜の形成によるが、保護膜は連続的で安定で表面に強く付着している。酸素に対するチタンの高い親和性のため、この酸化物の被膜は、材料の新しい切り口が大気に曝されると同時に自然に形成する。
【０００３】
チタン表面に形成された保護酸化物の層の性質、組成および厚さは環境条件に依存する。ほとんどの水環境中では、形成される酸化物はＴｉＯ2であるが、ＴｉＯ2、Ｔｉ2Ｏ3およびＴｉＯの混合物も形成することがある。自然に形成される酸化物の皮膜は約１０ｎｍの厚さに達するが、肉眼では見えない。
【０００４】
温度またはある気体に対するチタンの親和性等、ＴｉＯ2層の特性および組成を変えることのできる因子がいくつかある。また、金属表面の汚染またはゴミの存在も表面に不連続性をつくり、深刻な局所腐食プロセスを生み出す。建築に使用され刺激の多い環境性、工業的および都市雰囲気に曝されるチタンパネルの場合、パネルの表面特性およびそれらの組成を変えるこの種の現象が観察されている。
【０００５】
この種の酸化物および表面の汚染を除去する通常の条件に利用されるクリーニングおよび表面不動態化の方法は、数種類の溶液を用いる浸漬プロセスを必要とする。これらには、酸洗い、電解研磨および機械的処理がある。これらの方法は、その高コストのため、および元のパネルの表面特性を変えることがあるため、建築目的に利用されるパネルには利用できない。
【０００６】
したがって、本願に記載した問題の全てまたはほとんどを克服するのに役立つ、建築に利用されるチタンパネル等のチタンを含む表面をクリーニングする新規な方法が必要とされている。
【発明の開示】
【発明が解決しようとする課題】
【０００７】
本発明は、一般的に、ファサードを建設するのに利用されるチタンパネル等のチタン表面をクリーニングする方法を提供する問題を扱う。
【課題を解決するための手段】
【０００８】
本発明により提供される解決法は、（ｉ）無機酸の混合物から構成される、金属表面上で作用する活性剤を含む発現組成物および（ｉｉ）発現組成物の作用を阻害および中和する固定組成物を別々に含むクリーニング剤の開発およびチタン表面をクリーニングするためのこのクリーニング剤の利用に基づく。
【０００９】
本発明により提供されるクリーニング剤およびクリーニング方法を利用すると、チタン表面を損傷することなく容易かつ精密にクリーニングできる。
【００１０】
このクリーニング剤およびチタン表面をクリーニングするためのその利用の両方が、本発明の目的である。
【発明を実施するための最良の形態】
【００１１】
本発明は、（Ａ）無機酸の混合物から構成される、金属表面上で作用する活性剤を含む、本願で発現組成物と呼ぶ発現組成物またはクリーニング物質および（Ｂ）発現組成物の作用を阻害および中和する、本願で固定組成物と呼ぶ固定組成物または中和剤を別々に含む、チタン表面のクリーニングに有用なクリーニング剤を提供する。
【００１２】
より詳細には、本発明のクリーニング剤は、以下を別々に含む：
Ａ）以下から構成される発現組成物：
Ａ．１）硝酸とフッ化水素酸の混合物；
Ａ．２）増粘剤；
Ａ．３）界面活性剤；
Ａ．４）指示薬；
Ａ．５）水；および所望により
Ａ．６）噴射剤；および
Ｂ）以下を含む固定組成物：
Ｂ．１）アルカリ性水溶液；
Ｂ．２）増粘剤；
Ｂ．３）界面活性剤；
Ｂ．４）水；および
Ｂ．５）噴射剤。
Ａ．発現組成物
発現組成物の組成物は、水、活性剤および補助剤（増粘剤、界面活性剤および指示薬）および噴射剤を含む。
【００１３】
活性剤は、硝酸とフッ化水素酸の混合物から構成され、 金属表面（Ｔｉ）上で作用して、汚染、不純物および酸化物を除去する化学反応を起こす。有利には、活性剤は、金属支持体上のクリーニング化学反応の進行を妨げる保護的な効果も有する。活性剤は、通常水溶液の形態で加えられるが、発現組成物全体に対し重量で１から２０％の範囲の濃度で発現組成物中に存在する。特定の用途では、この活性剤は、発現組成物全体に対して重量で１％から１０％の硝酸および発現組成物全体に対して重量で０．１％から１％のフッ化水素酸を含む、硝酸とフッ化水素酸の混合物からなり、硝酸とフッ化水素酸の重量比は１０：１である。
【００１４】
増粘剤は、安定剤として発現組成物に導入され、粘度および選択されるレオロジー特性を与える。増粘剤としては、水溶性有機疑似塑性増粘剤、例えばセルロースタイプまたは天然ゴム、例えばキサンタンガムを使用できる。増粘剤は、発現組成物全体に対し重量で０．１％から１％の範囲の濃度で発現組成物に存在してよい。
【００１５】
界面活性剤は発現組成物の表面張力を変え、フォームの形成、発現組成物の安定化およびその成分の分散に有利に働く。可能性のある界面活性剤には、発現組成物全体に対し重量で０．１から１％の範囲の濃度のイオン性界面活性剤（アニオン性またはカチオン性）がある。特定の用途では、この界面活性剤はドデシル硫酸ナトリウムである。
【００１６】
指示薬は、色の変化により金属表面に塗布された発現組成物が固定組成物により中和される時間を示すために発現組成物に導入される。指示薬は、発現組成物の全重量に対し、重量で０．１％未満の濃度で発現組成物中に存在する。ある用途では、使用される指示薬はフェノールフタレインである。
発現組成物中に存在する水は、活性剤（存在する酸が水溶液で供給される場合）および／または補助剤（これらが水に溶解または懸濁して提供される場合）および／または発現溶液を調製するために加えられる水に由来する。
【００１７】
発現組成物は、数種の異なる形態の１つをとることができるが、例えば、フォームでも、ゲルでも、スプレーゲルでもよい。調製および包装の形態により、発現組成物は噴射剤を含んでも含まなくてもよい。
【００１８】
噴射剤は、包装された発現組成物に高い内圧を与え、クリーニングすべき金属表面への強制噴出を起こす物質である。噴射剤は溶離ガスまたは圧縮ガスでよい。
【００１９】
溶離ガスは、圧力の効果により周囲温度で液体であるが、大気圧で気体になる物質である。特定の温度で、高い使用圧力は一定であり、溶離噴射剤の蒸気圧と等しい。大気への噴射剤の蒸発は、スプレー形成または溶解している不揮発性物質の微細な液滴への変換を促し、ミクロフォームの形成に有利に働く。溶離ガスの例には、炭化水素またはフッ化炭化水素（ＨＦＣ）があるが、発現組成物全体に対し重量で５％から２０％の範囲の濃度で使用可能である。ある特定の用途において、噴射剤はＨＦＣ １３４ａ（１，１，１，２−テトラフルオロエタン）と特定されるフッ化炭化水素である。
【００２０】
圧縮ガスは、不溶性ガスの場合特に、容器中で発現組成物の表面に過剰圧力を保つ適切な圧力で注入され、液体の表面で作用する栓子と同様にこれを外へと引き出す物質である。内容物が排出されるにつれ、ガスは次第に大きな体積を占めるようになり、その初期圧力は低下し、したがって初期使用条件は変化する。窒素、二酸化炭素、亜酸化窒素および空気が、要求される使用圧力において適切な量で使用可能である。
【００２１】
既に述べたとおり、発現組成物の調製および包装は、関与する粘性ビヒクルの形態または種類に依存する。例としては、この発現組成物は以下の形態をとることができる：
ａ）フォーム（ＦＤ）、使用される噴射剤が溶離ガスの場合；
ｂ）スプレーゲル（ＳＰＤ）、使用される噴射剤が圧縮ガスの場合；または
ｃ）ゲル（ＧＤ）、噴射剤を含まない場合。
【００２２】
フォームおよびスプレーゲル製品は酸性媒体に耐性のある加圧容器中で、以下の成分［最終的な望ましい製品に規定されるパーセンテージを満たす適切な割合で、活性剤、補助剤（増粘剤、界面活性剤および指示薬のゲル形態または水性混合物として）、水および気体噴射剤］から調製される。この場合、発現組成物の塗布は、容器への充填から製品の塗布まで最大３時間の間隔で、好ましくは１時間未満で、例えばガンを用いる噴霧により行われる。
【００２３】
ゲルタイプの製品は、耐酸性容器中で以下の成分［最終的な望ましい製品に規定されるパーセンテージを満たす適切な割合で、活性剤、補助剤のゲルまたは水性混合物（増粘剤、界面活性剤および指示薬）および水］から調製される。この場合、製品の塗布は、容器への充填から製品の使用まで最大３時間の間隔で、好ましくは１時間未満で、例えばスポンジ鏝により行われる。
Ｂ．固定組成物
固定組成物は、発現組成物の作用を停止し、それを中和する中和活性剤、数種の補助剤（増粘剤および界面活性剤）、水および噴射剤から構成されている。
【００２４】
中和活性剤は、固定組成物が金属表面に塗布された時に発現組成物中に存在する酸の作用を阻害し、金属表面に対して酸が強烈に攻撃する可能性を低減し、クリーニング剤を中和してその回収および除去に有利に働く。中和活性剤としては、発現組成物中に存在する酸を中和できる塩基を、通常水溶液の形態で使用できる。例としては、この塩基はアルカリ金属水酸化物でよく、例えば固定組成物全体に対して重量で１％から２０％の濃度の水酸化ナトリウムまたは固定組成物に対して１％から最大許容濃度の間の濃度のリン酸三ナトリウムである。
【００２５】
増粘剤は、発現組成物に関して既に述べたのと同じ機能を有する。この場合、増粘剤として優先的にはシリケート系の無機製品が使用され、例えば固定組成物全体に対して重量で１から８％の範囲の濃度の海泡石が使用されるが、その理由はこの種の増粘剤が発現組成物のフッ化水素酸を中和することもできるからである。
【００２６】
界面活性剤は、発現組成物に関して既に述べたのと同じ機能を有する。固定組成物中に存在する界面活性剤は、イオン性界面活性剤（アニオン性またはカチオン性）に対応し、発現組成物に使用されるものと同じでも異なっていてもよい。界面活性剤は、固定組成物全体に対して重量で０．１から１％の範囲の濃度で固定組成物中に存在してよい。
【００２７】
固定組成物中に存在する水は、中和活性剤（塩基が水溶液で供給される場合）および／または補助剤（これらが水に溶解または懸濁して提供される場合）および／または固定組成物の体積を調整するために加えられる水のいずれかに由来する。
【００２８】
噴射剤は、溶離ガスまたは圧縮ガスでよいが、発現組成物に関して既に述べたのと同じ機能を有する。固定組成物中に存在する噴射剤は、発現組成物に使用するものと同じでも異なっていてもよい（固定組成物が噴射剤を含む場合）。噴射剤が溶離ガス、例えば炭化水素またはＨＦＣ １３４ａ等のＨＦＣである場合、固定組成物全体に対して重量で５から２０％の範囲の濃度で固定組成物に存在してよい。あるいは、噴射剤が圧縮ガス、例えば窒素、二酸化炭素、亜酸化窒素または空気である場合、上述のとおり、要求される使用温度で適切な量この噴射剤が使用される。
【００２９】
固定組成物は、噴射剤が溶離ガスである場合フォーム（ＦＦ）または噴射剤が圧縮ガスである場合スプレーゲル（ＳＧＦ）の形態等好適な提示の形態をとってよい。
【００３０】
どちらの製品（フォームおよびスプレーゲル）もアルカリ性媒体に耐性のある加圧容器に保存され、以下の成分［最終的な望ましい製品および噴射剤ガスに規定されるパーセンテージを満たす比率で、中和活性剤、補助剤（増粘剤と界面活性剤のゲルまたは水性混合物の形態）］から構成される。固定組成物の塗布は、容器への充填から製品の塗布まで３時間の最大間隔、好ましくは１時間未満の間隔をおいて、例えばガンを用いる噴霧により行われる。

[0001]
The present invention relates to cleaning agents for cleaning titanium surfaces and their use in procedures for cleaning titanium surfaces such as titanium facades and panels.
[Background]
[0002]
The excellent resistance of titanium and its alloys to corrosion depends on the formation of an oxide protective film, which is continuous, stable and strongly adhered to the surface. Due to the high affinity of titanium for oxygen, this oxide coating forms spontaneously as new cuts of material are exposed to the atmosphere.
[0003]
The nature, composition and thickness of the protective oxide layer formed on the titanium surface depends on the environmental conditions. In most water environments, the oxide formed is TiO 2 but may also form a mixture of TiO 2 , Ti 2 O 3 and TiO. The naturally formed oxide film reaches a thickness of about 10 nm, but is invisible to the naked eye.
[0004]
There are several factors that can change the properties and composition of the TiO 2 layer, such as temperature or the affinity of titanium for certain gases. Also, contamination of metal surfaces or the presence of debris can create discontinuities in the surface, creating severe local corrosion processes. In the case of titanium panels used in construction and exposed to irritating environmental, industrial and urban atmospheres, this type of phenomenon has been observed that changes the surface properties of the panels and their composition.
[0005]
The cleaning and surface passivation methods utilized in normal conditions to remove this type of oxide and surface contamination require a dipping process using several solutions. These include pickling, electropolishing and mechanical treatment. These methods are not available for panels used for construction purposes because of their high cost and may change the surface properties of the original panel.
[0006]
Accordingly, there is a need for a new method of cleaning titanium-containing surfaces, such as titanium panels used in construction, that helps overcome all or most of the problems described herein.
DISCLOSURE OF THE INVENTION
[Problems to be solved by the invention]
[0007]
The present invention generally addresses the problem of providing a method for cleaning a titanium surface, such as a titanium panel used to construct a facade.
[Means for Solving the Problems]
[0008]
The solution provided by the present invention comprises (i) an expression composition comprising an active agent acting on a metal surface composed of a mixture of inorganic acids and (ii) inhibiting and neutralizing the action of the expression composition Based on the development of a cleaning agent comprising a separate fixing composition and the use of this cleaning agent to clean the titanium surface.
[0009]
By using the cleaning agent and the cleaning method provided by the present invention, it is possible to clean easily and precisely without damaging the titanium surface.
[0010]
Both this cleaning agent and its use to clean the titanium surface are the object of the present invention.
BEST MODE FOR CARRYING OUT THE INVENTION
[0011]
The present invention comprises (A) an expression composition or cleaning substance, referred to herein as an expression composition, comprising an active agent that acts on a metal surface, composed of a mixture of inorganic acids, and (B) the action of the expression composition. Provided is a cleaning agent useful for cleaning titanium surfaces that separately comprises a fixing composition or neutralizing agent that inhibits and neutralizes, referred to herein as a fixing composition.
[0012]
More particularly, the cleaning agent of the present invention separately comprises:
A) Expression composition comprising:
A. 1) A mixture of nitric acid and hydrofluoric acid;
A. 2) thickener;
A. 3) surfactants;
A. 4) Indicator;
A. 5) water; and optionally A. 6) a propellant; and B) a fixing composition comprising:
B. 1) alkaline aqueous solution;
B. 2) thickener;
B. 3) surfactants;
B. 4) water; and B. 5) Propellant.
A. Expression composition The composition of the expression composition comprises water, active agents and adjuvants (thickeners, surfactants and indicators) and propellants.
[0013]
The activator is composed of a mixture of nitric acid and hydrofluoric acid and acts on the metal surface (Ti) to cause a chemical reaction that removes contamination, impurities and oxides. Advantageously, the activator also has a protective effect that prevents the progress of the cleaning chemistry on the metal support. The active agent is usually added in the form of an aqueous solution, but is present in the expression composition at a concentration ranging from 1 to 20% by weight relative to the total expression composition. For certain applications, the active agent comprises 1% to 10% nitric acid by weight with respect to the total expression composition and 0.1% to 1% hydrofluoric acid by weight with respect to the total expression composition. It consists of a mixture of nitric acid and hydrofluoric acid, and the weight ratio of nitric acid and hydrofluoric acid is 10: 1.
[0014]
Thickeners are introduced into the expression composition as stabilizers to give viscosity and selected rheological properties. As the thickener, water-soluble organic pseudoplastic thickeners such as cellulose type or natural rubber such as xanthan gum can be used. The thickening agent may be present in the expression composition at a concentration ranging from 0.1% to 1% by weight relative to the total expression composition.
[0015]
Surfactants alter the surface tension of the expression composition, favoring foam formation, stabilization of the expression composition and dispersion of its components. Possible surfactants include ionic surfactants (anionic or cationic) in concentrations ranging from 0.1 to 1% by weight with respect to the total expression composition. For certain applications, the surfactant is sodium dodecyl sulfate.
[0016]
The indicator is introduced into the expression composition to indicate the time during which the expression composition applied to the metal surface due to the color change is neutralized by the fixing composition. The indicator is present in the expression composition at a concentration of less than 0.1% by weight relative to the total weight of the expression composition. For some applications, the indicator used is phenolphthalein.
The water present in the expression composition may comprise an active agent (if the acid present is supplied in aqueous solution) and / or an adjuvant (if they are provided dissolved or suspended in water) and / or an expression solution. Derived from water added to prepare.
[0017]
The expression composition can take one of several different forms, but may be, for example, a foam, a gel, or a spray gel. Depending on the form of preparation and packaging, the expressed composition may or may not contain a propellant.
[0018]
The propellant is a substance that applies a high internal pressure to the packaged expression composition and causes forced ejection to the metal surface to be cleaned. The propellant may be an elution gas or a compressed gas.
[0019]
The eluting gas is a substance that is liquid at ambient temperature due to the effect of pressure, but becomes gas at atmospheric pressure. At a specific temperature, the high working pressure is constant and equal to the vapor pressure of the eluting propellant. Evaporation of the propellant to the atmosphere facilitates the formation of microfoams by promoting the formation of sprayed or dissolved non-volatile substances into fine droplets. Examples of eluent gases include hydrocarbons or fluorinated hydrocarbons (HFCs), but can be used at concentrations ranging from 5% to 20% by weight with respect to the total expression composition. In one particular application, the propellant is a fluorinated hydrocarbon identified as HFC 134a (1,1,1,2-tetrafluoroethane).
[0020]
Compressed gas is a substance that is injected at an appropriate pressure that keeps the overpressure on the surface of the expression composition in the container, especially in the case of insoluble gases, and pulls it out like a plug acting on the surface of the liquid. . As the contents are evacuated, the gas will gradually occupy a larger volume, its initial pressure will decrease, and therefore the initial use conditions will change. Nitrogen, carbon dioxide, nitrous oxide and air can be used in appropriate amounts at the required working pressure.
[0021]
As already mentioned, the preparation and packaging of the expression composition depends on the form or type of viscous vehicle involved. By way of example, the expression composition can take the following forms:
a) Foam (FD), when the propellant used is an eluent gas;
b) Spray gel (SPD), when the propellant used is a compressed gas; or c) Gel (GD), when no propellant is included.
[0022]
Foam and spray gel products should be placed in a pressurized container that is resistant to acidic media, with the following ingredients [active agent, adjuvant (thickener, interface, in appropriate proportions to meet the percentage specified in the final desired product] Active agent and indicator gel form or as an aqueous mixture), water and gas propellants]. In this case, the expression composition is applied at intervals of a maximum of 3 hours, preferably less than 1 hour, from filling the container to application of the product, for example by spraying with a gun.
[0023]
Gel-type products are prepared in acid-resistant containers with the following ingredients [active agent, adjuvant gel or aqueous mixture (thickener, surfactant, in an appropriate proportion to meet the percentage specified in the final desired product] And indicator) and water]. In this case, the application of the product is carried out at intervals of up to 3 hours, preferably less than 1 hour, from filling the container to the use of the product, for example by means of a sponge candy.
B. Fixing composition The fixing composition is a neutralizing activator that stops the action of the expression composition and neutralizes it, several adjuvants (thickeners and surfactants), water and propellants. It is composed of
[0024]
The neutralizing activator inhibits the action of the acid present in the expression composition when the fixing composition is applied to the metal surface, reduces the possibility of the acid attacking the metal surface strongly, and the cleaning agent Neutralizes and favors its recovery and removal. As the neutralizing activator, a base capable of neutralizing the acid present in the expression composition can be used usually in the form of an aqueous solution. By way of example, the base may be an alkali metal hydroxide, for example sodium hydroxide at a concentration of 1% to 20% by weight relative to the total fixing composition or from 1% to the maximum allowable concentration for the fixing composition. Between concentrations of trisodium phosphate.
[0025]
The thickener has the same function as already described for the expression composition. In this case, a silicate-based inorganic product is preferentially used as a thickener, for example, a foam stone having a concentration in the range of 1 to 8% by weight with respect to the whole fixing composition, for the reason. This is because this type of thickener can also neutralize hydrofluoric acid in the expression composition.
[0026]
The surfactant has the same function as already described for the expression composition. The surfactant present in the fixing composition corresponds to the ionic surfactant (anionic or cationic) and may be the same as or different from that used in the expression composition. The surfactant may be present in the fixing composition at a concentration in the range of 0.1 to 1% by weight with respect to the total fixing composition.
[0027]
The water present in the fixing composition is a neutralizing activator (if the base is supplied in an aqueous solution) and / or an adjuvant (if they are provided dissolved or suspended in water) and / or the fixing composition. Derived from any of the water added to adjust the volume of the water.
[0028]
The propellant may be an eluent gas or a compressed gas, but has the same function as previously described for the developing composition. The propellant present in the fixing composition may be the same as or different from that used in the expression composition (if the fixing composition includes a propellant). If the propellant is an eluent gas such as a hydrocarbon or HFC such as HFC 134a, it may be present in the fixed composition at a concentration in the range of 5 to 20% by weight relative to the total fixed composition. Alternatively, if the propellant is a compressed gas, such as nitrogen, carbon dioxide, nitrous oxide or air, an appropriate amount of this propellant is used at the required use temperature as described above.
[0029]
The fixed composition may take the form of a suitable presentation, such as a foam (FF) when the propellant is an elution gas or a spray gel (SGF) when the propellant is a compressed gas.
[0030]
Both products (foams and spray gels) are stored in pressurized containers that are resistant to alkaline media and are neutralized activators in proportions that meet the following ingredients [percentage specified in the final desired product and propellant gas] , Auxiliary agents (in the form of gels or aqueous mixtures of thickener and surfactant)]. The fixing composition is applied by spraying, for example using a gun, with a maximum interval of 3 hours, preferably less than 1 hour, from filling the container to application of the product.
[0031]
In certain applications, the present invention provides a cleaning agent that is useful for cleaning titanium surfaces and that also has the properties listed in Table 1.
Table 1
Cleaning agent A) expression composition comprising:
[Table 1]
B) Fixing composition comprising:
[Table 2]
In one particular application of a cleaning agent having the composition listed in Table 1, in the expression composition, the active agent is a mixture of 60% HNO 3 and 48% HF, the thickener is xanthan gum, and the surfactant is It is sodium dodecyl sulfate, the indicator is phenolphthalein, and the propellant (eluent gas) is HFC 134a.
[0036]
Similarly, in one particular application of a cleaning agent having the composition shown in Table 1, in the fixing composition, the base is sodium hydroxide, the thickening agent is leptite, and the surfactant is sodium dodecyl sulfate. And the propellant (eluent gas) is HFC 134a.
[0037]
The cleaning agent of the present invention is useful for cleaning titanium surfaces, particularly titanium architectural facades. Accordingly, the present invention provides a method for cleaning a titanium surface comprising the use of the cleaning agent of the present invention. More particularly, the method corresponds to the following steps:
a) applying the cleaning agent expression composition of the present invention to the titanium surface to be cleaned and allowing it to act for a period of time;
b) A step of applying the fixing composition of the cleaning agent of the present invention to the titanium surface already treated with the expression composition in step a) and allowing it to stand for a certain period of time;
c) suction of the surface already treated with the expression composition and the fixing composition in steps a) and b); and d) rinsing of the treated titanium surface after completion of step c).
[0038]
Step a), the development step, consists in uniformly applying the expression composition of the cleaning agent of the present invention over the entire titanium surface to be cleaned, but the surface is preferentially dry. If necessary, the titanium surface is dried using equipment that does not mechanically damage the metal surface. Depending on the form of presentation of the expression composition, it can be applied in various ways. For example, the foam developing composition (FD) and the spray gel developing composition (SGD) are applied with a suitable spray gun, and the gel developing composition (GD) takes care not to cause mechanical damage to the metal surface. Apply with sponge sponge while applying. After the expression composition is applied to the metal surface, it must be allowed to act for 15 seconds to 10 minutes before applying the fixing composition.
[0039]
Step b), ie the fixing step, consists in applying the fixing composition of the cleaning agent according to the invention to the metal surface already treated with the expression composition in step a) so that the surface is completely and uniformly covered. . Fixing compositions as foam (FF) and spray gel (SGF) are applied with a suitable spray gun. After applying the fixing composition, it is allowed to act for a period of time ranging from 30 seconds to 5 minutes, indicating that the active neutralizer of the fixing composition has neutralized the acid present in the fixing composition. Must be confirmed in advance by use of a change in pH or the use of a pH paper indicating strip before proceeding to the next step.
[0040]
After the fixing step, step c), i.e. a suction step, is carried out, wherein the already treated titanium surface is sucked to remove the cleaning agent from this treated surface. This suction is carefully performed using a suitable device so as not to damage the metal surface chemically or mechanically.
[0041]
Finally, after suction, step d), ie rinsing, is carried out, but the remainder of the product used in the previous step is removed using water jets at a temperature between 5 and 30 ° C.
[0042]
In a particular application, the titanium surface to be cleaned is a titanium building facade or a titanium panel used for the construction of a facade.
[0043]
The following examples illustrate the application of the present invention and do not limit the scope of the application in any way.
