現(xiàn)在濟(jì)南不銹鋼雕塑在城市建設(shè)中起著至關(guān)重要的作用,而由于經(jīng)常放置在室外,所以難免會(huì)有一些損傷。Now Ji'nan stainless steel sculpture in urban construction plays a vital role, and because often placed in the outdoor, so there will inevitably be some damage.
1.焊接引弧斑痕:焊工在山東不銹鋼雕塑金屬表面引弧時(shí),會(huì)造成表面粗糙缺陷。保護(hù)膜受損,留下潛在的腐蝕源。焊工應(yīng)在已經(jīng)焊好的焊道上或在焊縫接頭的側(cè)邊引弧。然后將引弧痕跡熔入焊縫中。Welding arc spot welder in Shandong: stainless steel sculpture metal arc surface, will cause surface defects. Protection film damage, leaving potential corrosion sources. The welder shall have good welding in welding or welding joint in the side of the arc. Then the arc trace is melted into the weld.
2.銹斑:濟(jì)南不銹鋼雕塑制作前或制作過程中有時(shí)會(huì)看到不銹鋼產(chǎn)品或設(shè)備上生銹,這說明表面受到嚴(yán)重污染。設(shè)備投入使用前必須把銹清除掉,徹底清理過的表面應(yīng)通過鐵試驗(yàn)和/或水試驗(yàn)進(jìn)行檢驗(yàn)。Rust: Ji'nan stainless steel sculpture making before or in the process of making sometimes see rust stainless steel products or equipment, the surface is seriously polluted. Rust must be removed before equipment is put into use. Thoroughly cleaned surfaces shall be inspected by iron test and / or water test.
3.焊接缺陷:焊接缺陷如:咬邊、未焊透、密集氣孔和裂紋不僅降低接頭的牢固性,而且還會(huì)成為縫隙腐蝕的腐蝕源。改善這種結(jié)果進(jìn)行清理操作時(shí),它們還會(huì)夾帶固體顆粒。山東不銹鋼雕塑公司提醒,這些缺陷可通過重新焊接或修磨后重焊進(jìn)行修補(bǔ)。Welding defects: welding defects such as: undercut, non penetration, dense pores and cracks not only reduce the firmness of the joint, but also become a corrosive source of crevice corrosion. To improve this result when cleaning operations, they will also entrained solid particles. Shandong stainless steel sculpture company reminded that these defects can be repaired by re welding or regrinding after repair.
4.劃痕:為了防止工藝潤滑劑或生成物和/或污物積留,必須對(duì)劃痕和其它粗糙表面進(jìn)行機(jī)械清理(如干噴砂,防火包磨料用玻璃珠)。Scratch: mechanical cleaning of scratches and other rough surfaces (e.g. dry blasting, fire resistant coated glass beads) must be done in order to prevent process lubricants and / or dirt retention.
5.油和油脂:有機(jī)物質(zhì)如:油,油脂甚至指印都會(huì)成為局部腐蝕的腐蝕源。由于這些物質(zhì)能起屏障作用,它們會(huì)影響化學(xué)和電化學(xué)清理效果,因而必須徹底清理掉。Oil and grease: organic substances such as oil, grease and even fingerprints will become the source of local corrosion corrosion. Since these substances can act as barriers, they can affect chemical and electrochemical cleaning effects and must be completely cleaned up.
6.油漆、粉筆和標(biāo)記筆?。哼@些污染物的影響與油和油脂的影響相似。建議用干凈的刷子和干凈的水或堿性清洗劑進(jìn)行洗滌,也可以使用高壓水或蒸汽沖洗。Paint, chalk and marker printing: the effects of these contaminants are similar to those of oils and fats. It is recommended to use a clean brush and clean water or alkaline cleaning agent for washing, can also use high-pressure water or steam wash.
7.熱回火色和其它氧化層:熱回火色是由于在高溫或長時(shí)間在較高度下停留所致。當(dāng)出現(xiàn)任何一種這類氧化層時(shí),金屬表面的鉻含量都會(huì)降低,造成這些區(qū)域的耐腐蝕性降低。濟(jì)南不銹鋼雕塑在這種情況下,不僅要消除熱回火色和其它氧化層,還應(yīng)對(duì)它們下面的貧鉻金屬層進(jìn)行清理。Back fire heat and other oxidation layer: back fire heat is due to the high temperature or long time at a height of stay by. When any such oxide occurs, the chromium content of the metal surface will be reduced, resulting in reduced corrosion resistance in these areas. Ji'nan stainless steel sculpture in this case, not only to eliminate the back fire heat and other metal oxide layer, the chromium depleted layer also deal with them the following cleaning.
8.粉塵:山東不銹鋼雕塑公司制作經(jīng)常是在有粉塵的場(chǎng)地進(jìn)行,空氣中常帶有許多粉塵,它們不斷地落在設(shè)備表面。它們可以用水或堿性溶液去除掉。不過,有附著力的塵垢有機(jī)膨潤土需要高壓水或蒸氣進(jìn)行清理。Dust: Shandong stainless steel sculpture company is often produced in the dust site, often with a lot of dust in the air, they continue to fall on the surface of the equipment. They can be removed with water or alkaline solution. However, there is dirt organic bentonite adhesion requires high pressure water or steam cleaning.
9.殘余粘合劑:撕掉膠帶和保護(hù)紙時(shí),粘合劑總有一部分殘留在不銹鋼表面。如果粘全劑還沒硬,可以用有機(jī)熔劑去除。但是,濟(jì)南不銹鋼雕塑當(dāng)曝露在光或空氣中時(shí),粘全劑變硬,形成縫隙腐蝕的腐蝕源。然后需要用細(xì)磨料進(jìn)行機(jī)械清理。Residual adhesive: tear tape and protective paper, adhesive is always a part of residues on the surface of stainless steel. If the agent is not sticky hard, can be used to remove organic solvent. However, Ji'nan stainless steel sculpture when exposed to light or air, the viscosity agent harden, corrosion source forming crevice corrosion. And then need to fine abrasive mechanical cleaning.
