導電涂料

用作導(dao)(dao)電(dian)涂(tu)料的(de)(de)導(dao)(dao)電(dian)物(wu)質主要是金屬粉末和石墨(mo)、炭黑等。采(cai)用不同(tong)的(de)(de)導(dao)(dao)電(dian)材料和載體(ti)可以制(zhi)成不同(tong)電(dian)阻(zu)值的(de)(de)導(dao)(dao)電(dian)涂(tu)料。部分導(dao)(dao)靜電(dian)涂(tu)料的(de)(de)電(dian)阻(zu)值范圍如(ru)下：

涂料組成(cheng)電阻(歐姆)銀(yin)粉、陶瓷、醇0.003~0.005金粉、陶瓷、芳烴0.003~0.01鋁(lv)、金、陶瓷、醇0.05~0.13銀(yin)、纖維素、酮(tong)0.01~0.03石(shi)墨、乳(ru)膠(jiao)、水25~75石(shi)墨、硅酸鹽(yan)、水100~300

導(dao)電(dian)涂料(liao)的(de)應(ying)用(yong)(yong)較廣，在電(dian)子工業領域、宇宙航(hang)行工業都有(you)(you)廣泛應(ying)用(yong)(yong)，在日用(yong)(yong)電(dian)子工業中也有(you)(you)應(ying)用(yong)(yong)，在需要導(dao)靜(jing)電(dian)的(de)場合也多采(cai)用(yong)(yong)導(dao)靜(jing)電(dian)涂料(liao)。

黃銅管的主要用(yong)途(tu)及(ji)種類(lei)

主(zhu)要應(ying)用于(yu)懸(xuan)浮物大于(yu)500PPM的(de)(de)(de)江河，七臺河電(dian)池涂布材料(liao)，海水(shui)(shui)或沿(yan)海地下水(shui)(shui)為(wei)冷卻介質的(de)(de)(de)各種熱交換(huan)器(qi)及冷凝器(qi) 冷凝管系列(lie)，該合金主(zhu)要化學組成為(wei)：Cu，As，余量為(wei) Zn. 該產(chan)品一般使(shi)用在河、湖(hu)、泉的(de)(de)(de)無懸(xuan)浮固(gu)形物腐蝕(shi)的(de)(de)(de)清新干凈水(shui)(shui)的(de)(de)(de)內陸電(dian)廠(chang)，電(dian)池涂布材料(liao)批(pi)發，還可用于(yu)其他液體和果汁處理設(she)備。

此外，電池涂布(bu)材(cai)料多少錢，該產(chan)品(pin)(pin)還廣泛用于制(zhi)糖和(he)食品(pin)(pin)工業，在(zai)這些環境中(zhong)，能(neng)阻(zu)止鋅的(de)浸析，電池涂布(bu)材(cai)料價格，在(zai)完全退(tui)火后，還可(ke)阻(zu)止應力腐蝕(shi)(shi)開裂、點(dian)蝕(shi)(shi)和(he)浸蝕(shi)(shi)。 冷凝管(guan)系列，該合(he)金(jin)主要化學(xue)組(zu)成為：Ni，Fe，Mn，余(yu)量Cu.該合(he)金(jin)中(zhong)的(de)Fe和(he)Mn的(de)加(jia)入(ru)大大改進了這種材(cai)料的(de)抗浸蝕(shi)(shi)性能(neng)。在(zai)清潔的(de)海(hai)水(shui)里，該合(he)金(jin)接受(shou)的(de)水(shui)流速度可(ke)達(da)2.2-2.5%/s。在(zai)微鹽溶液中(zhong)能(neng)接受(shou)的(de)速度可(ke)達(da)4m/s。該合(he)金(jin)可(ke)避免應力腐蝕(shi)(shi)開裂和(he)高溫(wen)點(dian)脫(tuo)鎳。

鎢銅合金主要應用

銅的分類

純(chun)銅:呈紫紅色﹐又稱紫銅。純(chun)銅密度為(wei)8.96﹐熔(rong)點為(wei)1083℃﹐具有優良的導電性﹑導熱性﹑延展(zhan)性和耐蝕性。主要

用(yong)(yong)于制作(zuo)發電機﹑母線﹑電纜﹑開關裝(zhuang)(zhuang)置﹑變壓器(qi)等(deng)電工器(qi)材和熱(re)(re)(re)交換器(qi)﹑管(guan)道﹑太陽能加(jia)(jia)熱(re)(re)(re)裝(zhuang)(zhuang)置的平板集(ji)熱(re)(re)(re)器(qi)等(deng)導熱(re)(re)(re)器(qi)材。銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)合金(jin):以(yi)純(chun)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)為基體加(jia)(jia)入一種或幾種其(qi)他(ta)元素(su)所構成的合金(jin)。常(chang)用(yong)(yong)的銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)合金(jin)分為黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)﹑青銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)﹑白銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)3大類。黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong):以(yi)鋅(xin)作(zuo)主要(yao)添加(jia)(jia)元素(su)的銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)合金(jin)﹐具有美觀的黃(huang)色﹐統(tong)稱(cheng)黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)。銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)鋅(xin)二元合金(jin)稱(cheng)普通黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)或稱(cheng)簡單黃(huang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)。
