好多客戶(hù)認(rèn)為自己的樣品是粉狀的就是用干法粒度儀測(cè)試，樣品液態(tài)的就用濕法粒度儀測(cè)試，其實(shí)這也是不太準(zhǔn)確的，下面小編給您介紹一下粒度儀濕法、干法的選擇。
A lot of customers that their sample is used for dry powder's particle size analyzer, sample liquid with wet particle size analyzer, which is actually not too accurate, following small series to introduce you to the choice of wet dry particle size analyzer.
樣品測(cè)試前是液態(tài)的用濕法粒度儀是沒(méi)錯(cuò)的，干法測(cè)試不了液態(tài)樣品這點(diǎn)是沒(méi)錯(cuò)的。
The sample is liquid before the test, and the wet particle sizer is correct. It is true that the dry test does not test the liquid sample.
樣品是粉末狀的用什么儀器測(cè)試呢？這選擇就很糾結(jié)了。拿金剛砂老說(shuō)您干法測(cè)試沒(méi)問(wèn)題，您用濕法也能測(cè)試，而且效果比干法還要好。水泥用干法測(cè)試沒(méi)問(wèn)題，用濕法測(cè)試您可能懷疑數(shù)據(jù)準(zhǔn)確性，因?yàn)樗嘣谒锸撬夥磻?yīng)的。我明確告訴您水泥完*可以用濕法測(cè)試，只不過(guò)分散介質(zhì)不要用水必須用無(wú)水乙醇測(cè)試。還有一些藥品找不到合適的液態(tài)分散介質(zhì)，這樣的就只能用干法測(cè)試了。您要測(cè)試的樣品是具體是濕法測(cè)試好還是干法測(cè)試好，**咨詢(xún)一下海鑫瑞的技術(shù)人員，我們會(huì)竭誠(chéng)為您服務(wù)。
The sample is powder. What instrument is used? This choice is very tangled. Take emery as you say. You have no problem with dry test. You can test it with wet method, and the effect is better than dry process. Dry test of cement is fine. Wet test. You may doubt the accuracy of the data because the cement is hydrolyzed in water. I specifically told you that cement can be completely wet tested, except that the dispersing medium does not use water and must be tested with absolute ethanol. Some drugs can't find the right liquid dispersing medium, so they can only be tested in dry way. The sample you want to test is whether the wet test is good or the dry test is good. It is better to consult Nekt's technical staff and we will serve you with all our heart.
