RELATED ARTICLES一、巖石法抗劈裂夾具概述:
適用于能(neng)制成(cheng)標(biao)準試(shi)(shi)件的煤和巖(yan)石。對(dui)實(shi)心圓柱體試(shi)(shi)件施加徑向壓縮(suo)線載(zai)荷至破(po)壞,確定(ding)試(shi)(shi)件大(da)拉應(ying)力。
二、巖石法抗劈裂夾具試件規格
標(biao)準試件應(ying)采用圓柱體,直徑宜為48-54mm,厚度宜為直徑的0.25-0.75倍(bei),試件內的大顆(ke)粒應(ying)小于直徑的1/10
三、試件數量
同一(yi)層煤或(huo)巖石試(shi)件的數量(liang)應(ying)不少于5塊
四、測試步驟
1、測定前(qian)應仔細核(he)對巖樣名稱和(he)編(bian)號,對試件(jian)顏色,顆粒(li)層理,裂(lie)隙(xi),風華程度(du),含水狀態以(yi)及加(jia)工(gong)過程中出(chu)現(xian)的(de)問題(ti)應進行描述(shu),并填(tian)入記錄表內
2、檢測(ce)試件加工(gong)精度(du),測(ce)量試件尺寸,并填入(ru)記(ji)錄表內
3、通過試(shi)(shi)(shi)(shi)(shi)件(jian)端(duan)面直徑(jing)的(de)兩(liang)端(duan),各(ge)畫(hua)一(yi)條(tiao)平行(xing)于軸(zhou)線(xian)(xian)的(de)直線(xian)(xian)作(zuo)為加(jia)載(zai)(zai)基線(xian)(xian),對于一(yi)般的(de)巖石或煤試(shi)(shi)(shi)(shi)(shi)件(jian),使用(yong)夾(jia)具(ju),把(ba)試(shi)(shi)(shi)(shi)(shi)件(jian)放(fang)(fang)入(ru)夾(jia)具(ju)內,夾(jia)具(ju)上,下刀刃(ren)對準加(jia)載(zai)(zai)基線(xian)(xian),用(yong)兩(liang)側夾(jia)持螺釘固(gu)定好試(shi)(shi)(shi)(shi)(shi)件(jian),或用(yong)兩(liang)根墊(dian)條(tiao)放(fang)(fang)在加(jia)載(zai)(zai)基線(xian)(xian)上,墊(dian)條(tiao)間用(yong)橡皮筋基線(xian)(xian),用(yong)兩(liang)側夾(jia)持螺釘固(gu)定好試(shi)(shi)(shi)(shi)(shi)件(jian)。電子萬(wan)能試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)機、液壓(ya)萬(wan)能試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)機、落錘沖擊(ji)(ji)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)機、均達(da)到國內同行(xing)業(ye)標(biao)準,公司主要生(sheng)產(chan)的(de)產(chan)品,品種齊全,性(xing)能穩定,質量(liang)可(ke)靠,以(yi)中高檔產(chan)品居多(duo)而且性(xing)價比(bi)高。其中包(bao)括:液壓(ya)萬(wan)能試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)機系(xi)(xi)列(lie)(lie)(lie)、電子萬(wan)能試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)機系(xi)(xi)列(lie)(lie)(lie)、沖擊(ji)(ji)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)機系(xi)(xi)列(lie)(lie)(lie),電工套管系(xi)(xi)列(lie)(lie)(lie),、臥式拉力試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)機、彎曲試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)機、建筑密封(feng)材料檢(jian)(jian)測(ce)(ce)儀器設(she)備、防(fang)水卷(juan)材檢(jian)(jian)測(ce)(ce)設(she)備、混凝土(tu)(tu)試(shi)(shi)(shi)(shi)(shi)驗(yan)(yan)檢(jian)(jian)測(ce)(ce)設(she)備,土(tu)(tu)工布檢(jian)(jian)測(ce)(ce)設(she)備、公路土(tu)(tu)工檢(jian)(jian)測(ce)(ce)、瀝青檢(jian)(jian)測(ce)(ce)設(she)備系(xi)(xi)列(lie)(lie)(lie)等產(chan)品,廣泛應用(yong)于各(ge)類實(shi)驗(yan)(yan)室、大專院校、科研單位及質量(liang)檢(jian)(jian)測(ce)(ce)機構等行(xing)業(ye)。
