工业门讲解不锈钢卷闸门的运输和保养

不锈钢之所以不容易生锈是因为表面有一层致密的钝化层存在,如果表面划伤碰撞破坏掉这层钝化层,或者一些腐蚀性特别强的介质存在不锈钢表面时,比如含氯物质或铁离子物质,都会对钝化层造成破坏,导致生锈。比如说不锈钢卷闸门、不锈卷帘门等等,在被划伤、碰撞和杂质物残留之后就会出现生锈。

Stainless steel does not rust easily because there is passivation layer surface has a layer of dense, if the surface scratch the collision destroyed the passivation layer, or some corrosive particularly strong medium existence of stainless steel surface, such as chlorine containing substances or iron material, will damage the passivation layer, leading to rust. For example, stainless steel gate, stainless steel shutter doors and so on, after being scratched, collision and impurity residues will be rust.

The following is the need to pay attention in the welding of stainless steel in the process of transportation:

A.不论是不锈钢件原材料或加工件在运输、装卸时,都应采用专用的吊装运输工具,避免不锈钢与钢丝绳或其他尖硬的碳素钢等接触,以免碰伤、划伤其表面。

A. regardless of stainless steel raw materials or processed in the transportation, loading and unloading, lifting transportation tool should be used special, avoid stainless steel and wire rope or other rigid steel contact, to avoid bumps, scratches the surface.

B.不锈钢件的加工场地要相对稳定,工作台上应铺垫橡胶板类软垫,以免损伤不锈钢表面。

The processing site B. stainless steel parts to be relatively stable, the table should be matting rubber plate cushion, so as not to damage the surface of stainless steel.

C.不锈钢件下料时,其板材应采用剪切或等离子切割;管材及其他型材应采用等离子切割或锯切。剪切时铺设橡胶类软垫,避免损伤其表面;等离子切割后,应及时清理割渣;锯切时,夹紧处应加垫儿保护。锯切后及时清理锯切处的油污、残渣等。

C. stainless steel material, the plate should be used to cut or plasma cutting; pipe and other forms should be cut or sawn by plasma. Shear rubber cushion laid, avoiding damage to the surface; plasma cutting, cutting slag should be cleaned in time; when sawing, clamping should be padded son protection. After sawing sawing at cleaning the oil residue, etc..

D.不锈钢件在安装焊接前,必须认真清理其表面的油污、灰尘等杂物。焊接时应尽量采用氩弧焊。如果采用手工电弧焊时,应用小电流快速焊,严禁在非焊区引弧。所用地线应选择适当位置,连接牢固,以免电弧烧伤表面或烧伤面积过大;焊接时应采取防飞溅措施。焊接后当清理焊渣时应用不锈钢扁铲,不得用碳钢类扁铲。焊缝处应认真修磨,使焊缝与母材表面光滑过渡,不得有熔渣、气孔、咬边、飞溅物、裂纹、未熔合等质量缺陷。

D. stainless steel in the installation before welding, oil, must be carefully cleaned the surface dust and debris. Welding should as far as possible the use of argon arc welding. If the manual arc welding, application of small current welding, is strictly prohibited in the non welding arc. The ground should choose the appropriate location, firm connection, so as to avoid the electric arc burn or burn surface area is too large; welding spatter measures should be taken to prevent. When cleaning up after welding welding slag of stainless steel flat shovel, shall not use the carbon steel flat shovel. Welding seam should be carefully grinding, the weld and base material surface smooth, no slag, porosity, undercut, splash, cracks, lack of fusion defects.

E.不锈钢件焊接完成后,应及时对表面进行清理。

E. stainless steel welding completed, should be timely to the surface cleaning.

F.不锈钢件表面处理完毕,应注意做好成品保护,避免人员抚摸,避免被油污、灰尘等二次污染  所以提醒广大客户,在订购不锈钢门的时候,一定要注意保养,不锈钢门一般都采用市场上最好的304不锈钢,其耐腐蚀、抗锈能力会更强更好。好产品也要好好用。

F. stainless steel surface treatment is completed, should pay attention to the protection of finished product, avoid to touch, to avoid pollution two oil, dust and so to remind customers when ordering, stainless steel door, must pay attention to maintenance, stainless steel door generally adopts 304 stainless steel the best on the market, its corrosion resistance, anti rust ability better. All products have to take with.
