① 不锈钢BA面是镜面吗
不锈钢BA面与镜面还是有一定的差别的,主要区别就是成像清晰度有差距。
BA就是在2B板的基础上,加了光亮处理,发白亮光,可以照出人像,但整体清晰度没有镜面的效果好。BA面一般都是钢厂整卷光亮处理的。
镜面板就是我们常说的8K不锈钢表面,镜面不锈钢是在普通2B板或者BA板面的基础上,再次抛光处理,亮度达到8K以上,可以清晰照出人像及头发眉毛纹路,成像是和镜子一样的效果。
同等规格、材质的镜面不锈钢价格比BA面的不锈钢价格高
② 不锈钢沾面粉怎么处理方法
抹布擦干净不就好了。
③ 不锈钢BA表面是什么样的,与2B比较,外观、工艺和用途上有什么不同
BA表面 外观上比较亮 类似镜面效果
304 的BA 2B表面区别很大 430的区别小一些
工艺的话 BA走的是光亮退火版线
用途上区别不大权 主要看产品要求美观就用BA
以前洗衣机都用BA 现在都改2B了
④ 不锈钢2B和BA面分别代表什么意思求解
不锈钢2B和BA面分别代表:
冷扎--退火酸洗--平整
2B
冷扎--光亮退火--平整
BA
主要区别在于退火,2B是退火、酸洗,表面有一定程度氧化,较暗;
BA光亮退火,表面不氧化,较亮
⑤ 不锈钢表面处理方法有哪些
不锈钢材料是一种使用范围非常广泛的材料,一般用于做柜面,或者是操作台等等,不锈钢材料的使用寿命比较长,清洁也比较简单,所以很多家具都是会私用不锈钢材料,但是不锈钢材料的表面一定要经过特殊的处理,让它具有一定的光泽度,才让视觉效果更好。不锈钢表面的处理技术有很多种,根据不同的使用功能有不同的方法,下面就是相关的知识介绍。
表面本色白化处理
不锈钢在加工过程中,经过卷板、扎边、焊接或者经过人工表面火烤加温处理,产生黑色氧化皮。这种坚硬的灰黑色氧化皮主要是NiCr2O4和NiF二种EO4成分,以前一般采用氢氟酸和硝酸进行强腐蚀方法去除。但这种方法成本大,污染环境,对人体有害,腐蚀性较大,逐渐被淘汰。目前对氧化皮处理方法主要有二种:
⑴喷砂(丸)法:主要是采用喷微玻璃珠的方法,除去表面的黑色氧化皮。
⑵化学法:使用一种无污染的酸洗钝化膏和常温无毒害的带有无机添加剂的清洗液进行浸洗。从而达到不锈钢本色的白化处理目的。处理好后基本上看上去是一无光的色泽。这种方法对大型、复杂产品较适用。
不锈钢表面镜面光亮处理方法
根据不锈钢产品的复杂程度和用户要求情况不同可分别采用机械抛光、化学抛光、电化学抛光等方法来达到镜面光泽。
表面着色处理
不锈钢着色不仅赋予不锈钢制品各种颜色,增加产品的花色品种,而且提高产品耐磨性和耐腐蚀性。
不锈钢着色方法
⑴化学氧化着色法:就是在特定溶液中,通过化学氧化形成膜的颜色,有重铬酸盐法、混合钠盐法、硫化法、酸性氧化法和碱性氧化法。一般“茵科法”(INCO)使用较多,不过要想保证一批产品色泽一致的话,必须用参比电极来控制。
⑵电化学氧化着色法;是在特定溶液中,通过电化学氧化形成膜的颜色。
⑶离子沉积氧化物着色法;就是将不锈钢工件放在真空镀膜机中进行真空蒸发镀。例如:镀钛金的手表壳、手表带,一般是金黄色。这种方法适用于大批量产品加工。因为投资大,成本高,小批量产品不合算。
⑷高温氧化着色法;是在特定的熔盐中,浸入工件保持在一定的工艺参数,使工件形成一定厚度氧化膜,而呈现出各种不同色泽。
⑸气相裂解着色法。气相裂解着色法:较为复杂,在工业中应用较少。
不同的用途对不锈钢的表面有不一样的要求,不锈钢的表面一定要处理平整,并进行合理的抛光才可以使用。目前处理不锈钢表面的方法主要有上面几种,不同的方法得倒的效果不一样,价格和成本也有不同,一般都是根据不锈钢的需求来进行方法选择,上面几种方法都是比较常见的不锈钢不仅要对表面进行本色白化处理,镜面光亮也要进行特殊处理。
⑥ 不锈钢BA面是指什么呢
镜面效果,但是达不到8K
⑦ 暖通:什么是不锈钢BA,EP处理
316L是一种材质,EP指的是不锈钢管表面处理,表面处理分为AP,BA,EP.根据价格高低EP>BA>AP.AP:不做处理BA:光辉烧钝EP:电解抛光
⑧ 什么是不锈钢板2B面不锈钢板2B面和BA面是啥意思
2B(雾面):冷轧后经热处理、酸洗,再以精轧加工使表面为适度之光亮者。由于表面光滑,易于再研磨,使表面更加光亮,用途广泛,如餐具、建材等。采用改善机械性能的表面处理后,几乎满足所有用途。
BA (亮面):经冷轧后施以光亮退火,并经过平整得到的产品。表面光泽度极好,有很高的反射率。如同镜面的表面。用于家电产品、镜子、厨房设备、装饰材料等。
⑨ 不锈钢食品管BA表面是什么意思
不锈钢BA管――BrightAnnealedtube(真空光亮退火管),它是气氛保护热处理(BrightAnnealed)的简称,又叫:不锈钢BA管,洁净管,光亮退火管,无缝管. BA表面的定义来自于美国标准ASTM A480 和欧盟标准EN10088。见下列英文解释。
The most common definitions of these surface finishes are provided by ASTM A480 and EN 10088. In both cases it is the cold rolled manufacturing method that is specified rather than specific, measurable characteristics about the surface. We have used ASTM A480 as an example:
ASTM A480:
No. 2D - A smooth, non-reflective cold-rolled annealed and pickled or descaled finish. This non-directional finish is favourable for the retention of lubricants in deep drawing applications.
No. 2B - A smooth, moderately reflective cold-rolled annealed and pickled or descaled finish typically proced by imparting a final light cold-rolled pass using [large diameter] polished rolls. This general-purpose finish is more readily polished than No 1 or 2D finishes. Proct with 2B finish is normally supplied in the annealed plus lightly cold-rolled condition unless a tensile-rolled [harder and stronger] proct is specified.
Bright Annealed [BA] Finish- A smooth, bright, reflective finish typically proced by cold rolling followed by annealing in a protective atmosphere so as to prevent oxidation and scaling ring annealing.
2B
2B is the most widely used stainless steel surface finish. It is especially common in instrial, chemical and food processing applications such as process vessels and tanks. It is also used in some architectural applications that will not be closely examined for uniformity of finish such as downpipes and gutters.
When specifying this finish think about these attributes:
2B is the most economical finish
It is highly corrosion resistant because it has been chemically pickled and is smooth
Over broad areas and between batches etc., it is not uniform and may not match in appearance
It has been proced in the mill and can't be matched after fabrication
It if often protected by plastic films until final cleanup and commissioning
2D
2D is used around the world in applications where its low reflectivity is important. The largest application is in roofing materials. The surface is rougher than 2B and retains lubricants better making it appealing for deep drawring. 2D surfaces are not designed for appearance so the limitations on matching of weld and other surface damage is not as critical. Railcars are a typical example where thicker sheet and ongoing abrasive damage make the rougher 2D a suitable finish.
When specifying this finish think about these attributes:
2D is not commonly available in Australia
It is highly corrosion resistant because it has been chemically pickled and is relatively smooth
Over broad areas and between batches etc., it is not uniform and may not match
It has been proced in the mill and can't be matched after fabrication。
Bright Annealed (BA)
The classic use of a BA finish is domestic: the interior of a dishwasher or clothes washing machine. In the clothes washer, it also provides a smooth, non-abrasive surface for the clothes to slide around. The mirror like surface is also used in road mirrors where a precise image is not required.
When specifying this finish think about these attributes:
BA is common in some grades and thicknesses, but not all
It is highly corrosion resistant because it is very smooth
Different batches may not match
It is has been proced in the mill and can't be exactly matched after fabrication although a mechanical mirror polish can be close.
