mso-hansi-font-family:"Times New Roman"">一、用途:
mso-hansi-font-family:"Times New Roman"">依據(jù)GB/T5480.5-2004 "Times New Roman"">礦物棉及其制品試驗(yàn)方法渣球含量之標(biāo)準(zhǔn)設(shè)計制做,可對玻璃棉及其制品,礦渣棉、巖棉、及其制品,硅酸鋁棉及其制品進(jìn)行渣球含量進(jìn)行分析。具有體積小、外形美觀實(shí)用等特點(diǎn),是實(shí)驗(yàn)室必備之儀器。
mso-hansi-font-family:"Times New Roman"">二、渣球含量分析測定儀技術(shù)參數(shù):
mso-hansi-font-family:"Times New Roman"">玻璃轉(zhuǎn)子流量計:25-250mL/min
mso-hansi-font-family:"Times New Roman"">分離筒:內(nèi)徑80mm "Times New Roman"">;高380mm
mso-hansi-font-family:"Times New Roman"">纖維收集器
mso-hansi-font-family:"Times New Roman"">渣球收集器
mso-hansi-font-family:"Times New Roman"">外形尺寸:310×260×590mm
mso-hansi-font-family:"Times New Roman"">三、渣球含量分析測定儀使用步驟:
1、制備試樣
mso-hansi-font-family:"Times New Roman"">按GB/T5480.5-2004 "Times New Roman"">的規(guī)定選取式樣,切取全厚度的試樣11g "Times New Roman"">左右。在對于玻璃棉及其制品,在(500±20 "Times New Roman"">)℃下灼燒30min mso-hansi-font-family:"Times New Roman"">以上;對于硅酸棉及其制品,在(700±20 mso-hansi-font-family:"Times New Roman"">)℃ "Times New Roman"">下灼燒30min "Times New Roman"">以上。除盡粘結(jié)劑再稱量精確到0.01g "Times New Roman"">。試樣數(shù)量按產(chǎn)品標(biāo)準(zhǔn)的規(guī)定,但不應(yīng)少于3 "Times New Roman"">個。
2、壓制試樣
mso-hansi-font-family:"Times New Roman"">把稱量好的試樣放入相應(yīng)的試樣筒內(nèi),放于壓榨器上進(jìn)行手動螺旋加壓。
3、潤濕試樣
mso-hansi-font-family:"Times New Roman"">將壓制好的試樣取出,放于250mL "Times New Roman"">量杯內(nèi),加入表面活性劑溶液50mL "Times New Roman"">,并充分?jǐn)嚢瑁估w維在溶液中得到潤濕和分散。
4、分離試驗(yàn)
mso-hansi-font-family:"Times New Roman"">將試樣全部移入分離筒中。
mso-hansi-font-family:"Times New Roman"">打開水源開關(guān),使轉(zhuǎn)子流量計的流量示值為60mL/min,保持此流量直至纖維在水中得到分散和懸浮。
mso-hansi-font-family:"Times New Roman"">加大水流量至(120-180 "Times New Roman"">)mL/min "Times New Roman"">,繼續(xù)分離10min "Times New Roman"">左右。
mso-hansi-font-family:"Times New Roman"">待分離筒內(nèi)水澄清后,打開分離筒下端的排渣閥,借助水流把渣球完全排入邊長不大于產(chǎn)品標(biāo)準(zhǔn)規(guī)定的篩孔邊長的標(biāo)準(zhǔn)篩內(nèi)。
mso-hansi-font-family:"Times New Roman"">檢查纖維收集器內(nèi)的纖維中是否含有渣球,若有渣球應(yīng)將其放入分離器內(nèi)在進(jìn)行分離。
mso-hansi-font-family:"Times New Roman"">干燥
mso-hansi-font-family:"Times New Roman"">將盛有渣球的篩子放入電熱干燥箱內(nèi),在(105-110)℃ mso-hansi-font-family:"Times New Roman"">溫度下烘干至少20min "Times New Roman"">。
mso-hansi-font-family:"Times New Roman"">篩分
mso-hansi-font-family:"Times New Roman"">將干燥的渣球移入產(chǎn)品標(biāo)準(zhǔn)規(guī)定的篩孔的標(biāo)準(zhǔn)篩內(nèi),加入3 mso-hansi-font-family:"Times New Roman"">只直徑為(20±1 "Times New Roman"">)mm的陶瓷球,蓋裝后啟動振篩機(jī)篩分15min mso-hansi-font-family:"Times New Roman"">。
mso-hansi-font-family:"Times New Roman"">稱量
mso-hansi-font-family:"Times New Roman"">將篩分后的渣球放在天平上稱重,讀數(shù)精確到0.01g mso-hansi-font-family:"Times New Roman"">。
mso-hansi-font-family:"Times New Roman"">計算及試驗(yàn)結(jié)果
mso-hansi-font-family:"Times New Roman"">計算
mso-hansi-font-family:"Times New Roman"">渣球含量Sh "Times New Roman"">按下式計算:
???????? Sh=m/mo×100
mso-hansi-font-family:"Times New Roman"">式中:
?Sh— "Times New Roman"">渣球含量,單位為百分?jǐn)?shù)(%);
m—渣球質(zhì)量,單位為克(g mso-hansi-font-family:"Times New Roman"">)。
mo-試樣質(zhì)量,單位為克(g mso-hansi-font-family:"Times New Roman"">)。
? "Times New Roman"">試驗(yàn)結(jié)果
mso-hansi-font-family:"Times New Roman"">試驗(yàn)結(jié)果以算術(shù)平均值表示,精確到小數(shù)點(diǎn)后第一位。同時報出所有篩孔的孔徑。
mso-hansi-font-family:"Times New Roman"">實(shí)驗(yàn)完畢后清理好以便下次使用。
