耐火澆注料廠家，通泰耐材對耐火澆注料試樣檢測標準的說明：

? ? ?耐(nai)火(huo)(huo)澆(jiao)(jiao)注(zhu)料(liao)(liao)作為(wei)高(gao)溫(wen)工業窯爐內(nei)襯使用比較普遍，如何生產讓用戶放心的(de)產品。這(zhe)就需(xu)要(yao)(yao)對耐(nai)火(huo)(huo)澆(jiao)(jiao)注(zhu)料(liao)(liao)試(shi)樣(yang)(yang)(yang)進行檢(jian)測(ce)，那么關于(yu)耐(nai)火(huo)(huo)澆(jiao)(jiao)注(zhu)料(liao)(liao)試(shi)樣(yang)(yang)(yang)檢(jian)測(ce)標準(zhun)(zhun)究竟是什么呢？只要(yao)(yao)是根據標準(zhun)(zhun)對耐(nai)火(huo)(huo)澆(jiao)(jiao)注(zhu)料(liao)(liao)原料(liao)(liao)攪(jiao)拌、試(shi)樣(yang)(yang)(yang)的(de)成型、試(shi)樣(yang)(yang)(yang)尺寸、試(shi)樣(yang)(yang)(yang)的(de)養護和試(shi)樣(yang)(yang)(yang)的(de)烘干做出以下的(de)規定：

一、原料的攪拌

? ? 對試(shi)驗料(liao)進行充分(fen)攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)是為(wei)了把各種原料(liao)成分(fen)混(hun)(hun)合(he)均勻,并使其獲得(de)較好的(de)(de)流動性,因(yin)此,攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)強度和(he)攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)時(shi)(shi)間(jian)(jian)必須達到。根據(ju)YB/T5202,攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)速度為(wei)公轉(zhuan)(40±5)r/min,自轉(zhuan)(120±s)r/min,結合(he)劑加(jia)入量確至0.1g結合(he)劑/100g干(gan)料(liao)。在攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)2min后稍(shao)停,清理粘(zhan)附于攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)葉片和(he)攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)桶邊沿的(de)(de)泥料(liao),再攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)總攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)時(shi)(shi)間(jian)(jian)共(gong)4.5min。根據(ju)ASTMC860,先(xian)干(gan)混(hun)(hun)1min,低(di)速攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)12min,同時(shi)(shi)加(jia)入結合(he)劑量的(de)(de)90%,然(ran)后在50~60r/min下攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)1min,并緩慢加(jia)入剩余的(de)(de)結合(he)劑至達到希望(wang)的(de)(de)流動性,全部攪(jiao)(jiao)(jiao)(jiao)拌(ban)(ban)(ban)(ban)(ban)(ban)(ban)(ban)時(shi)(shi)間(jian)(jian)為(wei)3mIn±10s(重質澆(jiao)注料(liao)),5min±10(輕質隔熱澆(jiao)注料(liao)),4~6min(強振動澆(jiao)注料(liao))。

二、試樣的成型

? ? 根據YB/T5202,將試(shi)(shi)模(mo)固(gu)定于(yu)振動臺上填裝試(shi)(shi)驗(yan)料(liao)至試(shi)(shi)模(mo)一(yi)半(ban)高度,并分布均(jun)勻,振動30s,然后將試(shi)(shi)模(mo)內混(hun)合料(liao)表面(mian)(mian)(mian)拉毛,在(zai)填裝試(shi)(shi)驗(yan)料(liao)超(chao)(chao)過試(shi)(shi)模(mo)邊沿再(zai)振30s,從振動臺上取(qu)下試(shi)(shi)模(mo),去掉模(mo)套(tao),用(yong)鏝刀輕(qing)輕(qing)除去多余試(shi)(shi)驗(yan)料(liao)并抹平(ping)表面(mian)(mian)(mian),從加水開始(shi)至試(shi)(shi)樣成型(xing)的全(quan)部(bu)(bu)時(shi)間不超(chao)(chao)過10min。但是(shi),實際試(shi)(shi)驗(yan)過程中采用(yong)連續加料(liao)的方式直至試(shi)(shi)模(mo)邊沿平(ping)齊,振動時(shi)間以氣泡排出較少和表面(mian)(mian)(mian)泛漿時(shi)為準,一(yi)般為1min左右,然后邊振動邊抹平(ping)試(shi)(shi)樣表面(mian)(mian)(mian),振動時(shi)間30s,全(quan)部(bu)(bu)成型(xing)時(shi)間不超(chao)(chao)過10min。

三、試樣尺寸

試(shi)樣(yang)尺寸需根據不同的檢測項(xiang)目來確定目前采(cai)用的試(shi)樣(yang)尺寸為:

A型230mm×114mm×65mm,用(yong)于測定(ding)(ding)熱震穩定(ding)(ding)性(YB/T2206.1~,2-1998);

B型160mm×40mm×40mm,用(yong)于測定(ding)抗折強度(du)(du)、耐(nai)壓強度(du)(du)(YB/T5201-1993)、顯氣孔率和(he)體(ti)積密度(du)(du)(YB/T5200-1993)、線變化(hua)率等(YB/T5203-1993)。

C型中φ(160-180)mm×(20~30)mm,用于測定熱(re)導率(YB/T4130—2005)；

D型φ50mm×50mm,用于測定荷(he)重軟化溫度(YB/T2203-1998)；

E型φ20~25mm×100mm,或20mm×20mm×100mm,用于測定熱膨脹率(YB/T5205-1993);

F型100mm×100mm×30mm,用于測定(ding)耐磨性(GB/T18301-2001)；

G型,50mm×50mm×50mm,用(yong)于測定扛爆裂性(xing)(YB/T4117-2003)。

四、試樣的養護

? ?由(you)于澆注料(liao)的結(jie)合劑不同,試樣(yang)的養護(hu)方法應有所不同,本文只對(dui)水硬性、熱(re)硬性和氣硬性3種(zhong)硬化方式作了規(gui)定。

①水(shui)硬性結合(he)劑包括鋁(lv)酸(suan)鈣(gai)水(shui)泥鋁(lv)酸(suan)鋇(bei)水(shui)泥、硅酸(suan)鹽水(shui)泥、P氧(yang)化鋁(lv)等;一般情況下將成型好(hao)的試樣帶試模(mo)置(zhi)于相對(dui)濕度不(bu)小于90%,溫度(20±3)℃的養(yang)護箱中(zhong)養(yang)護24h后脫模(mo),再(zai)在相同條件下養(yang)護24h。

②氣硬性結合(he)劑(ji)有(you)磷酸鹽、流酸鹽、氯化物、溶膠等,一般采用自(zi)然養護方法。

③熱(re)(re)硬性結(jie)合劑(ji)有(you)有(you)機結(jie)合劑(ji)和(he)化學結(jie)合劑(ji)等,一(yi)般(ban)采用加(jia)熱(re)(re)處理后再自然養護的方法進行。

五、試樣的烘干

? ? 根據YB/T5202,對需要測定(ding)線變化(hua)率的(de)試樣(yang)養(yang)護后測量(liang)試樣(yang)尺寸,隨后放(fang)入電熱干燥箱中,以20~30℃/h速(su)度升溫(wen)至110℃,在(zai)(110±5)℃下烘干至恒量(liang)。但是(shi),在(zai)實際工作中,保溫(wen)時間通(tong)常為(wei)12~24h,而不(bu)是(shi)以恒量(liang)為(wei)標準。?

? ? 對于干(gan)燥(zao)后試樣的存放,一般為(wei)隨爐自(zi)然(ran)冷卻(或(huo)移入干(gan)燥(zao)器)后,存人(ren)干(gan)燥(zao)處以(yi)防止(zhi)吸收水分,存放時間不(bu)超過3天。
