輝縣市金鑲玉石墨模具制品有限公司介紹目前國內石墨坩堝出(chu)產(chan)工(gong)(gong)藝(yi)有(you)兩(liang)種：塑性成(cheng)型(xing)出(chu)產(chan)工(gong)(gong)藝(yi)和冷等靜(jing)壓成(cheng)型(xing)出(chu)產(chan)工(gong)(gong)藝(yi)。以粘土為粘結劑的塑性成(cheng)型(xing)工(gong)(gong)藝(yi)出(chu)產(chan)周期(qi)長，勞動強度大(da)，工(gong)(gong)效低，用煤燒(shao)成(cheng)，污(wu)染大(da)，但因出(chu)資少，國內多選(xuan)用此(ci)工(gong)(gong)藝(yi);而等靜(jing)壓設備(bei)限制成(cheng)型(xing)工(gong)(gong)藝(yi)選(xuan)用清潔動力天然(ran)氣燒(shao)結，則(ze)從根本(ben)上處理了污(wu)染問(wen)題(ti)，且減(jian)少出(chu)產(chan)工(gong)(gong)序(xu)近10道，周期(qi)短，工(gong)(gong)效高。下面小(xiao)編就給我(wo)們(men)詳細(xi)說(shuo)說(shuo)。

1、等靜壓與等靜壓成型：

等(deng)靜壓：是(shi)指在各個(ge)方向上對通過密(mi)封的物(wu)料一同施加持平的壓力狀況;

等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)成型：是(shi)將待(dai)壓(ya)(ya)(ya)(ya)(ya)物料通(tong)(tong)過密(mi)封后置(zhi)于高(gao)壓(ya)(ya)(ya)(ya)(ya)容器(qi)中，運用(yong)(yong)(yong)液體介(jie)質(zhi)不(bu)行(xing)壓(ya)(ya)(ya)(ya)(ya)縮的(de)(de)性(xing)質(zhi)和(he)均勻傳(chuan)遞壓(ya)(ya)(ya)(ya)(ya)力的(de)(de)性(xing)質(zhi)從各(ge)個方向(xiang)對物料進行(xing)均勻加(jia)壓(ya)(ya)(ya)(ya)(ya)，當液體介(jie)質(zhi)通(tong)(tong)過壓(ya)(ya)(ya)(ya)(ya)力泵注入壓(ya)(ya)(ya)(ya)(ya)力容器(qi)時，依據流體力學(xue)原理，其壓(ya)(ya)(ya)(ya)(ya)強(qiang)巨細不(bu)變且均勻地傳(chuan)遞到各(ge)個方向(xiang)，因而高(gao)壓(ya)(ya)(ya)(ya)(ya)容器(qi)中的(de)(de)粉料在各(ge)個方向(xiang)上遭到的(de)(de)壓(ya)(ya)(ya)(ya)(ya)力是(shi)均勻的(de)(de)和(he)巨細一(yi)起的(de)(de)。選(xuan)用(yong)(yong)(yong)上述辦法使粉料致(zhi)密(mi)成坯體的(de)(de)辦法稱為等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)成型。等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)成型按成型時溫度區分，還可(ke)分成冷(leng)(leng)等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)、溫等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)和(he)熱(re)等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)，等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)石墨(mo)(mo)的(de)(de)出(chu)產(chan)大多選(xuan)用(yong)(yong)(yong)冷(leng)(leng)等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)，只需極少數選(xuan)用(yong)(yong)(yong)熱(re)等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)出(chu)產(chan)工藝。如(ru)：神州(zhou)6號逃逸設備上的(de)(de)石墨(mo)(mo)材料就是(shi)選(xuan)用(yong)(yong)(yong)熱(re)等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)技(ji)能出(chu)產(chan)的(de)(de)，價值高(gao)達2萬元/kg,民用(yong)(yong)(yong)等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)石墨(mo)(mo)材料一(yi)般選(xuan)用(yong)(yong)(yong)冷(leng)(leng)等(deng)(deng)(deng)靜(jing)(jing)(jing)(jing)(jing)壓(ya)(ya)(ya)(ya)(ya)技(ji)能出(chu)產(chan)。

2、等靜(jing)壓(ya)石(shi)(shi)墨：等靜(jing)壓(ya)石(shi)(shi)墨是指(zhi)選用(yong)等靜(jing)壓(ya)成型方式出產的(de)石(shi)(shi)墨材(cai)料。等靜(jing)壓(ya)石(shi)(shi)墨由于成型過程中通過液(ye)體壓(ya)強(qiang)均勻(yun)不變施壓(ya)，制得的(de)石(shi)(shi)墨材(cai)料性質優異，具有：成型規格大(da);坯料組織結(jie)構均勻(yun);密度(du)高，強(qiang)度(du)高;各向(xiang)同性(特性與尺(chi)度(du)、形狀、取樣(yang)方向(xiang)無(wu)關)等利益，因而等靜(jing)壓(ya)石(shi)(shi)墨也稱為“各向(xiang)同性”石(shi)(shi)墨。

各向同性石墨的定義(yi)：是機械功用(yong)、電氣功用(yong)和(he)熱功用(yong)等靜態特性具有各向同性，異(yi)向比為1～1.1的人造石墨。更多石墨各制品相關(guan)問(wen)題，歡(huan)迎(ying)您的咨詢!
