鈍化的機(jī)理可用薄膜理論來解釋，即認(rèn)為鈍化是由于金屬與氧化性質(zhì)作用，作用時(shí)在金屬表面生成一種非常薄的、致密的、覆蓋性能良好的、牢固地吸附在金屬表面上的鈍化膜。這層膜成**相存在，通常是氧化金屬的化合物。它起著把金屬與腐蝕介質(zhì)完全隔開的作用，陜西表面處理設(shè)備，防止金屬與腐蝕介質(zhì)接觸，從而使金屬基本停止溶解形成鈍態(tài)達(dá)到防腐蝕的作用。 </p> <p> 鈍化的優(yōu)點(diǎn)： </p> <p> 1、與傳統(tǒng)的物理封閉法相比，鈍化處理后具有不增加工件厚度和改變顏色的特點(diǎn)、提高了產(chǎn)品的精密度和附加值，使操作更方便 </p> <p> 2、由于鈍化的過程屬于無反應(yīng)狀態(tài)進(jìn)行，鈍化劑可反復(fù)添加使用，因此壽命更長(zhǎng)、成本更經(jīng)濟(jì)； </p> <p>

燙印俗稱“燙金”，燙印的實(shí)質(zhì)是轉(zhuǎn)印，是把燙金紙上面的圖案通過熱和壓力的作用轉(zhuǎn)移到承印物上面的工藝過程。模的壓力產(chǎn)生凹陷，印刷的字或者圖案不易模糊，就可以圖案、標(biāo)識(shí)、文本或者圖片就可以牢牢地黏在產(chǎn)品表面。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 燙印模和箔是燙印工藝兩個(gè)關(guān)鍵組成，燙印模一般由鎂、黃銅和鋼構(gòu)成，有的會(huì)在金屬燙印模表面上使用硅橡膠用于不是很平整的表面。燙印模箔主要包括載體，離型層，保護(hù)層和裝飾層。 </p> <p> 燙印過程包含4個(gè)步驟： </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> (1)燙印箔與基材接觸; </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> (2)憑借熱量和壓力，轉(zhuǎn)印層被轉(zhuǎn)印到基材表面上; </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> (3)卸除壓力，剝離聚酯薄膜; </p> <p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> (4)進(jìn)給燙印箔，換上將要燙印的承印件。 </p><p> 金屬是一種具有光澤（即對(duì)可見光強(qiáng)烈反射）、富有延展性、容易導(dǎo)電、導(dǎo)熱等性質(zhì)的物質(zhì)。地球上的絕大多數(shù)金屬元素是以化合態(tài)存在于自然界中的。這是因?yàn)槎鄶?shù)金屬的化學(xué)性質(zhì)比較活潑，只有極少數(shù)的金屬如金、銀等以游離態(tài)存在。金屬在自然界中普遍存在，在生活中應(yīng)用極為普遍，是在現(xiàn)代工業(yè)中非常重要和應(yīng)用**多的一類物質(zhì)。 </p> <p> 由于金屬的電子傾向脫離，因此具有良好的導(dǎo)電性，且金屬元素在化合物中通常帶正價(jià)電，但當(dāng)溫度越高時(shí)，因?yàn)槭艿搅嗽雍说臒嵴鹗幾璧K，電阻將會(huì)變大。金屬分子之間的連結(jié)是金屬鍵，因此隨意更換位置都可再重新建立連結(jié)，這也是金屬伸展性良好的原因。但拋丸靈活性差，受場(chǎng)地限制，清理工件時(shí)有些盲目性，在工件內(nèi)表面易產(chǎn)生清理不到的死角。</p><div

</p> <p> 浸透 </p> <p> <br /> </p> <p> 是一種微孔（細(xì)縫）滲透密封工藝。將密封介質(zhì)（通常是低粘度液體）通過自然滲透（即微孔自吸）、抽真空和加壓等方法滲入微孔（細(xì)縫）中，將縫隙填充滿，然后通過自然(室溫）、冷卻或加熱等方法將縫隙里的密封介質(zhì)固化，達(dá)到密封縫隙的作用。 </p> <p> <br /> </p> <p> <br

利用柔性拋光工具和磨料顆?；蚱渌麙伖饨橘|(zhì)對(duì)工件表面進(jìn)行的修飾加工。拋光不能提高工件的尺寸精度或幾何形狀精度，而是以得到光滑表面或鏡面光澤為目的，有時(shí)也用以消除光澤（消光）。鋼鐵的氧化處理可用化學(xué)或電化學(xué)方法?；瘜W(xué)方法是將工件放入氧化溶液中依靠化學(xué)作用在工件表面形成氧化膜。陜西表面處理設(shè)備</p><p
