目前在標(biāo)準(zhǔn)范圍內(nèi)環(huán)境試驗(yàn)的代表性標(biāo)準(zhǔn)是GJB150《設(shè)備環(huán)境試驗(yàn)方法》，砂塵試驗(yàn)是GJB150中規(guī)定的試驗(yàn)項(xiàng)目。砂塵試驗(yàn)(人工模擬環(huán)境采用SC-010砂塵試驗(yàn)箱)是用來確定軍設(shè)備對(duì)飛散砂塵環(huán)境的適應(yīng)能力。 </p> <p> <br /> </p> <p> 本試驗(yàn)方法適用于在使用，河南防水測試箱、貯存和運(yùn)輸過程中有可能暴露在充滿干砂和塵士的大氣中的所有機(jī)械、電氣、電子和機(jī)電產(chǎn)品，也可供某些產(chǎn)品(如某些機(jī)車船舶設(shè)備)的塵密封試驗(yàn)。 </p> <p> <br /> </p> <p> 由于標(biāo)準(zhǔn)規(guī)定的試驗(yàn)方法中要求相對(duì)濕度小于30%，所以要考核因砂塵作用使水汽凝聚而加速腐蝕等潮濕條件下產(chǎn)生的電化學(xué)作用的影響是無法實(shí)施的。如果環(huán)境中的相對(duì)濕度較大，河南防水測試箱，空氣中的水汽會(huì)使砂塵微粒粘結(jié)成團(tuán)，河南防水測試箱，則在同樣的風(fēng)速條件下變不容易使砂塵微粒吹起，這樣試驗(yàn)效果就會(huì)明顯受影響。耐腐蝕鹽霧測試箱廠家直銷。河南防水測試箱</p><div

人工模擬鹽霧試驗(yàn)又包括中性鹽霧試驗(yàn)、醋酸鹽霧試驗(yàn)、銅鹽加速醋酸鹽霧試驗(yàn)、交變鹽霧試驗(yàn)。1、中性鹽霧試驗(yàn)(NSS試驗(yàn))是出現(xiàn)**早目前應(yīng)用領(lǐng)域**廣的一種加速腐蝕試驗(yàn)方法。它采用5%的氯化鈉鹽水溶液，溶液PH值調(diào)在中性范圍(6～7)作為噴霧用的溶液。試驗(yàn)溫度均取35℃，要求鹽霧的沉降率在1～2ml/。2、醋酸鹽霧試驗(yàn)(ASS試驗(yàn))是在中性鹽霧試驗(yàn)的基礎(chǔ)上發(fā)展起來的。它是在5%氯化鈉溶液中加入一些冰醋酸，使溶液的PH值降為3左右，溶液變成酸性，***形成的鹽霧也由中性鹽霧變成酸性。它的腐蝕速度要比NSS試驗(yàn)**倍左右。3、銅鹽加速醋酸鹽霧試驗(yàn)(CASS試驗(yàn))是國外新近發(fā)展起來的一種快速鹽霧腐蝕試驗(yàn)，試驗(yàn)溫度為50℃，鹽溶液中加入少量銅鹽—氯化銅，強(qiáng)烈誘發(fā)腐蝕。它的腐蝕速度大約是NSS試驗(yàn)的8倍。4、交變鹽霧試驗(yàn)是一種綜合鹽霧試驗(yàn)，它實(shí)際上是中性鹽霧試驗(yàn)加恒定濕熱試驗(yàn)。它主要用于空腔型的整機(jī)產(chǎn)品，通過潮態(tài)環(huán)境的滲透，使鹽霧腐蝕不但在產(chǎn)品表面產(chǎn)生，也在產(chǎn)品內(nèi)部產(chǎn)生。它是將產(chǎn)品在鹽霧和濕熱兩種環(huán)境條件下交替轉(zhuǎn)換，***考核整機(jī)產(chǎn)品的電性能和機(jī)械性能有無變化。河南防水測試箱鹽霧試驗(yàn)機(jī)需要定期進(jìn)行維護(hù)和保養(yǎng)，規(guī)范化的日常保養(yǎng)可以提高鹽霧試驗(yàn)機(jī)的試驗(yàn)準(zhǔn)確性和延長設(shè)備使用壽命。</p><div

鹽霧試驗(yàn)機(jī)的全稱是鹽水噴霧試驗(yàn)機(jī)，主要是用來測試樣品的耐腐蝕性。目前***的應(yīng)用在航天工業(yè)、汽車電子、電子電工、手機(jī)數(shù)碼、塑膠制品、金屬材料等等行業(yè)，測試其耐腐蝕性能，也是模擬自然條件或工作條件下的極端情況，用以了解各樣品的性能溫度情況。鹽霧試驗(yàn)機(jī)的工作原理比較單一，主要就是利用帶腐蝕性的氣液體對(duì)樣品進(jìn)行噴灑，通過噴灑腐蝕氣液體直到樣品的出現(xiàn)腐蝕現(xiàn)象的這個(gè)時(shí)間，作為樣品的耐腐蝕性能，時(shí)間越長，就表示樣品的耐腐蝕性越好。鹽霧試驗(yàn)的工作原理是將腐蝕性溶液壓縮成空氣噴霧，然后將噴霧盡量包裹樣品的各個(gè)面，這個(gè)測試可以連續(xù)或者循環(huán)進(jìn)行，直到樣品出現(xiàn)了預(yù)期的腐蝕現(xiàn)象為止。然后記錄下腐蝕的時(shí)間，來表明樣品的耐腐蝕性。一般鹽霧試驗(yàn)機(jī)里的腐蝕溶液主要是5%濃度的氯化鈉溶液或者在氯化鈉溶液中每升添加，來作為鹽霧腐蝕溶液。另外，鹽霧試驗(yàn)機(jī)可以自主調(diào)控鹽霧的沉降量和噴灑量，保證試驗(yàn)溫度恒定，操作便捷，試驗(yàn)環(huán)境穩(wěn)定。因此常常用來測試日常生活用品或工業(yè)用品的耐腐蝕性能。
