三、使用方法：
1，制備試樣
按GB/T5480.5-2004的規(guī)定選取式樣，切取全厚度的試樣11g左右。在對于玻璃棉及其制品，在（500±20）℃下灼燒30min以上；對于硅酸棉及其制品，在（700±20）℃下灼燒30min以上。除盡粘結(jié)劑再稱量**到0.01g。試樣數(shù)量按產(chǎn)品標(biāo)準(zhǔn)的規(guī)定，但不應(yīng)少于3個。
2，壓制試樣
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
將壓制好的試樣取出，放于250mL量杯內(nèi)，加入表面活性劑溶液50mL，并充分?jǐn)嚢?，使纖維在溶液中得到潤濕和分散。
4，分離試驗
?將試樣全部移入分離筒中。
?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。
?加大水流量至（120-180）mL/min，繼續(xù)分離10min左右。
?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)。
?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。
5，干燥
將盛有渣球的篩子放入電熱干燥箱內(nèi)，在（105-110）℃溫度下烘干至少20min。
6，篩分
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只直徑為（20±1）mm的陶瓷球，蓋裝后啟動振篩機(jī)篩分15min。
7，稱量
將篩分后的渣球放在天平上稱重，讀數(shù)**到0.01g。
8，計算
渣球含量sｈ-按下式計算：
Sh=m/moX100
式中：
sｈ—渣球含量，單位為百分?jǐn)?shù)（％）；
m—渣球質(zhì)量，單位為克（g）。
m0-試樣質(zhì)量，單位為克（g）。
9，試驗結(jié)果
試驗結(jié)果以算術(shù)平均值表示，**到小數(shù)點后A位。同時報出所有篩孔的孔徑。
實驗完畢后清理好以便下次使用.
Third, use method:
1. Prepare the sample
Select the pattern according to GB / T5480.5-2004, and cut about 11g of the full thickness sample. For glass wool and its products, it is fired at (500 ± 20) ℃ for more than 30min; for silicic acid wool and its products, it is fired at (700 ± 20) ℃ for more than 30min. Remove the binder and weigh ** to 0.01g. The number of samples shall be as specified in the product standard, but shall not be less than three.
2. Pressed sample
Put the weighed sample into the corresponding sample tube, put it on the squeezer and perform manual spiral pressure.
3. Wetting the sample
The pressed sample was taken out, placed in a 250 mL measuring cup, and 50 mL of a surfactant solution was added, and thoroughly stirred to make the fibers wet and dispersed in the solution.
4. Separation test
? Move all the samples into the separation cylinder.
? Turn on the water source switch and make the flowmeter display value of the rotor flowmeter 60mL / min. Keep this flowrate until the fibers are dispersed and suspended in the water.
? Increase the water flow to (120-180) mL / min, and continue to separate for about 10 minutes.
? After the water in the separation cylinder is clarified, open the slag discharge valve at the lower end of the separation cylinder and use the water flow to completely discharge the slag ball into a standard sieve whose side length is not greater than the sieve hole side length specified in the product standard.
? Check whether there are slag balls in the fiber in the fiber collector. If there are slag balls, put them in the separator to separate them.
5, dry
Place the slag ball-containing sieve in an electric drying box and dry it at (105-110) ° C for at least 20 minutes.
6. Screening
Move the dried slag ball into the standard sieve of the sieve hole specified in the product standard, add 3 ceramic balls with a diameter of (20 ± 1) mm, and start the vibrating screen for 15 minutes after capping.
7, weighing
The sieved slag ball was weighed on a balance, and the reading was ** to 0.01g.
8. Calculation
The slag ball content sh-calculated as follows:
Sh = m / moX100
In the formula:
sh—slag content, unit is percentage (%);
m—mass of slag ball, unit is gram (g).
m0-sample mass in grams (g).
9. Test results
The test results are expressed as arithmetic mean, ** to the decimal place. At the same time report the pore size of all sieve holes.
Clean up after the experiment for next use.
