不(bu)(bu)(bu)銹(xiu)鋼(gang)(gang)井(jing)蓋(gai)如何鑒別真偽？1、硫酸銅點試(shi)驗(yan)能很快區別普(pu)通碳素鋼(gang)(gang)和所(suo)有(you)類型(xing)的不(bu)(bu)(bu)銹(xiu)鋼(gang)(gang)井(jing)蓋(gai)。在硫酸銅溶液中，普(pu)通碳素鋼(gang)(gang)或鐵幾秒(miao)鐘內就會形成一層表面(mian)金(jin)屬銅，而(er)不(bu)(bu)(bu)銹(xiu)鋼(gang)(gang)井(jing)蓋(gai)的表面(mian)則(ze)不(bu)(bu)(bu)產生銅沉(chen)淀(dian)或顯示銅的顏色。2、磁(ci)(ci)性(xing)試(shi)驗(yan)磁(ci)(ci)性(xing)試(shi)驗(yan)能區別退(tui)火奧氏體不(bu)(bu)(bu)銹(xiu)鋼(gang)(gang)井(jing)蓋(gai)與鐵索體不(bu)(bu)(bu)銹(xiu)鋼(gang)(gang)井(jing)蓋(gai)。不(bu)(bu)(bu)銹(xiu)鋼(gang)(gang)井(jing)蓋(gai)是非磁(ci)(ci)性(xing)鋼(gang)(gang)，但經大壓下冷加(jia)工后(hou)將具(ju)有(you)輕微(wei)的磁(ci)(ci)性(xing);而(er)純粹的鉻(ge)鋼(gang)(gang)和低合金(jin)鋼(gang)(gang)都是強磁(ci)(ci)性(xing)鋼(gang)(gang)。
加載試(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)，每(mei)批隨機(ji)抽取2套(tao)檢(jian)(jian)(jian)查井蓋(gai)進(jin)行(xing)承載能力試(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)。如有(you)一套(tao)不(bu)符合(he)6。14的要求，則再抽取2套(tao)重(zhong)復本項試(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)。如再有(you)一套(tao)不(bu)符合(he)要求，則該批檢(jian)(jian)(jian)查井蓋(gai)為不(bu)合(he)格(ge)。每(mei)批產(chan)品(pin)必須有(you)該批材質(zhi)的檢(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)(yan)報告。型(xing)式檢(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)(yan)遇有(you)下(xia)列情(qing)況之一時，應進(jin)行(xing)型(xing)式檢(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)(yan)。a。生產(chan)滿1年；b。新產(chan)品(pin)生產(chan)定(ding)型(xing)鑒(jian)定(ding)；c。產(chan)品(pin)設計、生產(chan)工藝、使用材料變更(geng)；d。出(chu)廠試(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)與(yu)上一次(ci)型(xing)式試(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)有(you)較大差異；e。停(ting)產(chan)后恢復生產(chan)；f。國(guo)家(jia)質(zhi)量監督機(ji)構提出(chu)進(jin)行(xing)型(xing)式試(shi)驗(yan)(yan)(yan)(yan)(yan)(yan)g。使用單(dan)位提出(chu)進(jin)行(xing)型(xing)式檢(jian)(jian)(jian)驗(yan)(yan)(yan)(yan)(yan)(yan)要求。
不銹(xiu)鋼雨水(shui)井(jing)蓋板也叫(jiao)不銹(xiu)鋼漏(lou)水(shui)篦子,是采用不銹(xiu)鋼材質(zhi)焊接(jie)而成,具有高(gao)強(qiang)度防(fang)銹(xiu),防(fang)腐(fu)性(xing)能,排(pai)水(shui)面積大,承重性(xing)能好,不銹(xiu)鋼漏(lou)水(shui)篦子可(ke)根據客戶要求及實際使用環境進行相應(ying)設計,適(shi)應(ying)性(xing)強(qiang),相較普通井(jing)蓋板具有使用年(nian)限(xian)長久在每個(ge)試(shi)管內分別放入試(shi)樣的(de)幾克鉆屑，然后向每個(ge)試(shi)管注入數(shu)目相等的(de)體積濃度為(wei)40~50%的(de)鹽酸(suan)溶液;3分鐘后，溶液將(jiang)發生一定的(de)變(bian)化。
