濟寧建材(cai)廠(chang):一般(ban)來說,燒(shao)結(jie)實(shi)心(xin)磚的(de)生產(chan)工藝(yi)包括四個部分(fen):原(yuan)料(liao)(liao)制備、坯(pi)料(liao)(liao)成(cheng)型(xing)、濕(shi)坯(pi)干(gan)燥和(he)(he)成(cheng)品(pin)燒(shao)結(jie)。磚塊原(yuan)料(liao)(liao)開采后,有(you)些原(yuan)料(liao)(liao)經過加水攪(jiao)拌和(he)(he)碾壓設備處理,有(you)些原(yuan)料(liao)(liao)不行。如(ru)山土、煤矸(gan)石、頁巖(yan)等原(yuan)料(liao)(liao),需要(yao)破碎(sui)細碎(sui)后再加水攪(jiao)拌碾壓。原(yuan)料(liao)(liao)的(de)選擇和(he)(he)制備直接影(ying)響成(cheng)品(pin)磚的(de)質量。所(suo)以常說原(yuan)料(liao)(liao)是(shi)燒(shao)結(jie)實(shi)心(xin)磚的(de)基礎(chu)。這說明了原(yuan)料(liao)(liao)和(he)(he)原(yuan)料(liao)(liao)的(de)重要(yao)性。
濟寧建材廠:所選制磚(zhuan)原料經制備處理后,進入成(cheng)(cheng)型(xing)車(che)間進行成(cheng)(cheng)型(xing)。我們國(guo)家的(de)繞結磚(zhuan)坯料成(cheng)(cheng)型(xing)方法(fa)基本上(shang)都是用塑(su)料擠(ji)壓(ya)(ya)(ya)成(cheng)(cheng)型(xing)。塑(su)料擠(ji)壓(ya)(ya)(ya)成(cheng)(cheng)型(xing)有三種方法(fa)。即塑(su)料擠(ji)壓(ya)(ya)(ya)成(cheng)(cheng)型(xing);半硬(ying)塑(su)料擠(ji)壓(ya)(ya)(ya)成(cheng)(cheng)型(xing)和硬(ying)塑(su)料擠(ji)壓(ya)(ya)(ya)成(cheng)(cheng)型(xing)。
濟(ji)寧(ning)建材廠:這三種(zhong)擠(ji)壓(ya)(ya)成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)方法根據成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)含(han)水(shui)率(lv)的(de)(de)(de)不(bu)同(tong)而不(bu)同(tong)。當濕坯(pi)成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)含(han)水(shui)率(lv)大于16%(干基(ji)以下均為干基(ji))時,為塑性擠(ji)壓(ya)(ya)成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)。當濕坯(pi)成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)含(han)水(shui)率(lv)為14-16%時,為半(ban)硬(ying)塑擠(ji)壓(ya)(ya)成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)。當濕坯(pi)成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)含(han)水(shui)率(lv)為12-14%時,為硬(ying)塑擠(ji)壓(ya)(ya)成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)。坯(pi)料(liao)成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)包括:原料(liao)進入成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)車間(jian)前的(de)(de)(de)進料(liao)、攪拌(ban)、加水(shui)和(he)(he)碾壓(ya)(ya)設備處理部分;成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)磚機后,成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)出(chu)合格(ge)的(de)(de)(de)泥(ni)條(tiao)和(he)(he)濕坯(pi)。成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)要達到(dao)產(chan)(chan)品的(de)(de)(de)形狀(zhuang)和(he)(he)結構,就是(shi)成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)產(chan)(chan)品的(de)(de)(de)形狀(zhuang)和(he)(he)結構。所以常說(shuo)成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)是(shi)基(ji)礎,也(ye)就是(shi)說(shuo),要求的(de)(de)(de)產(chan)(chan)品的(de)(de)(de)外形和(he)(he)結構是(shi)通(tong)過成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)塑造(zao)出(chu)來(lai)的(de)(de)(de)。也(ye)就是(shi)說(shuo),成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)是(shi)過程中的(de)(de)(de)基(ji)本含(han)義。因為成(cheng)(cheng)(cheng)(cheng)型(xing)(xing)的(de)(de)(de)坯(pi)料(liao)質量直接關(guan)系到(dao)成(cheng)(cheng)(cheng)(cheng)品磚的(de)(de)(de)外觀(guan)質量。
