日常生活中的(de)點滴都離(li)不開充(chong)電(dian)電(dian)池(chi),電(dian)j是充(chong)電(dian)電(dian)池(chi)不可或缺的(de)一部分。不同種類的(de)充(chong)電(dian)電(dian)池(chi)電(dian)ji材料會有不同的(de)性能(neng)和(he)優勢與(yu)劣(lie)勢,充(chong)電(dian)電(dian)池(chi)電(dian)j的(de)性能(neng)甚(shen)至可以影響我們(men)的(de)生活質(zhi)量。常見(jian)的(de)充(chong)電(dian)電(dian)池(chi)電(dian)j容易(yi)得銅、鉑、汞等金(jin)屬(shu)材料。下面就讓小編深度解析(xi)一下石墨電(dian)ji材料的(de)優點及選(xuan)擇標準。

石(shi)墨電(dian)(dian)ji,應以(yi)煅燒(shao)石(shi)油焦、針狀焦為(wei)原料(liao)(liao),以(yi)醋酸(suan)甲脂為(wei)粘結劑(ji),根據煅燒(shao)、調(diao)味品、混捏(nie)、抑止、培燒(shao)、石(shi)墨化、工業生產(chan)而成,以(yi)電(dian)(dian)孤的(de)形式釋放出來(lai)電(dian)(dian)磁能(neng)升(sheng)溫(wen)鍛造加熱爐料(liao)(liao)電(dian)(dian)導體。根據其產(chan)品執(zhi)行標(biao)準可分為(wei)一般功(gong)率、轉速(su)高(gao)總數chao轉速(su)高(gao)的(de)。石(shi)墨電(dian)(dian)ji材(cai)料(liao)(liao)的(de)飛速(su)發展(zhan)已經(jing)非常健全應用也十分廣泛(fan)。根源在于石(shi)墨電(dian)(dian)j具有銅等其它金屬材(cai)料(liao)(liao)材(cai)料(liao)(liao)材(cai)料(liao)(liao)材(cai)料(liao)(liao)電(dian)(dian)ji材(cai)料(liao)(liao)不具備的(de)優勢。

*先與石(shi)(shi)(shi)墨(mo)電(dian)ji和銅(tong)(tong)(tong)(tong)比照,石(shi)(shi)(shi)墨(mo)的(de)(de)(de)價格降低,尤其(qi)是(shi)(shi)伴隨著近些年銅(tong)(tong)(tong)(tong)的(de)(de)(de)價格漸漸地上漲,石(shi)(shi)(shi)墨(mo)變為市場(chang)里便宜實惠電(dian)ji材(cai)料(liao)。雖然一樣容積石(shi)(shi)(shi)墨(mo)材(cai)料(liao)比銅(tong)(tong)(tong)(tong)劃(hua)得來(lai)百分之30到百分60,但(dan)是(shi)(shi)石(shi)(shi)(shi)墨(mo)的(de)(de)(de)性能(neng)(neng)一點也沒有(you)(you)優惠折扣材(cai)料(liao),尤其(qi)是(shi)(shi)銅(tong)(tong)(tong)(tong)有(you)(you)一定的(de)(de)(de)延展性很容易變形(xing),銅(tong)(tong)(tong)(tong)凈重(zhong)大部分場(chang)地不(bu)(bu)建議(yi)。石(shi)(shi)(shi)墨(mo)不(bu)(bu)僅承載力而(er)且材(cai)料(liao)輕。此外石(shi)(shi)(shi)墨(mo)的(de)(de)(de)放電(dian)速率可以達到銅(tong)(tong)(tong)(tong)兩至三倍。充電(dian)放電(dian)時石(shi)(shi)(shi)墨(mo)表面還(huan)能(neng)(neng)夠釋放出氧(yang)分子,創建一層(ceng)保護(hu)膜大大減少了石(shi)(shi)(shi)墨(mo)材(cai)料(liao)傷(shang)害。

銅(tong)的熔點(dian)(dian)只有(you)(you)1000度(du)左右,而石(shi)(shi)墨(mo)的熔點(dian)(dian)可(ke)以(yi)達到近4000℃,這就導致石(shi)(shi)墨(mo)材料在(zai)(zai)制(zhi)造(zao)方面具(ju)有(you)(you)一定的優(you)勢,尤其是將(jiang)其制(zhi)成細肋(lei)電(dian)ji。石(shi)(shi)墨(mo)的線(xian)膨脹系數和密(mi)度(du)遠低于銅(tong),因(yin)此石(shi)(shi)墨(mo)不僅可(ke)以(yi)大幅度(du)降(jiang)低工業(ye)設備(bei)耗費,還(huan)可(ke)以(yi)作(zuo)為規模性(xing)生(sheng)產制(zhi)造(zao)生(sheng)產行業(ye)。在(zai)(zai)節(jie)省許多財(cai)力(li)物力(li)前提下,很容(rong)易進(jin)行機電(dian)一體(ti)化(hua)和自動化(hua)生(sheng)產生(sheng)產制(zhi)造(zao)。選(xuan)擇石(shi)(shi)墨(mo)電(dian)ji時,有(you)(you)四個選(xuan)擇標準。

*先(xian)石墨(mo)電ji材(cai)料(liao)的(de)(de)可吸入顆粒(li)越(yue)(yue)(yue)(yue)小,其(qi)充(chong)(chong)電放電越(yue)(yue)(yue)(yue)均勻穩定,因而在使用中(zhong)一(yi)(yi)(yi)選可吸入顆粒(li)小一(yi)(yi)(yi)點石墨(mo)材(cai)料(liao)。石墨(mo)電ji的(de)(de)抗(kang)拉(la)強度(du)(du)指(zhi)數值與(yu)材(cai)料(liao)抗(kang)壓(ya)強度(du)(du)密切相(xiang)關,設備(bei)(bei)和新品的(de)(de)精密度(du)(du)越(yue)(yue)(yue)(yue)大(da),對抗(kang)壓(ya)強度(du)(du)要求也(ye)越(yue)(yue)(yue)(yue)高。石墨(mo)的(de)(de)邵氏硬(ying)度(du)(du)是衡量其(qi)性能指(zhi)標值,根據自己的(de)(de)喜好對抗(kang)拉(la)強度(du)(du)規定不一(yi)(yi)(yi)樣。抗(kang)壓(ya)強度(du)(du)越(yue)(yue)(yue)(yue)多(duo)充(chong)(chong)電放電耗費越(yue)(yue)(yue)(yue)小,但對生產線(xian)設備(bei)(bei)和投(tou)入的(de)(de)務必越(yue)(yue)(yue)(yue)多(duo)。z后材(cai)料(liao)的(de)(de)原來(lai)電阻器全是一(yi)(yi)(yi)個重要的(de)(de)標準。相(xiang)同的(de)(de)情況下電阻越(yue)(yue)(yue)(yue)大(da)充(chong)(chong)電放電減輕,馬上展現了這一(yi)(yi)(yi)材(cai)料(liao)的(de)(de)應(ying)用領域。
