Ukala kanjani ukuminyana okuxekethile?

Ithuluzi elimele ikhwalithi ephezulu lokuhlolwa kokuminyana kwenqwaba embonini yempushana →i-DRK-D82 umhloli wokuminyana ngobuningi

I-DRK-D82 loose density tester iyithuluzi elisetshenziselwa ukuhlola ukuminyana okuxekethile kwezimpushana ezihlukahlukene. Ivumelana nendinganiso kazwelonke ye-People's Republic of China - ukulinganisa kokuminyana kwenqwaba endleleni yokuhlola impahla ebonakalayo engu-GB/T16913 kanye nokukalwa kokuminyana ngobuningi ku-GB/T 31057.1, futhi iyimitha evamile evamile yokuminyana kwenqwaba.

Izinyathelo zokuhlola:
Beka isilinda sokulinganisa endaweni yesikhulumi, setha iplathifomu ibe ileveli, faka induku yokuvimbela kufaneli ukuze uvimbe indawo ephumayo, futhi uqinisekise ukuthi induku yokuvimba isendaweni eqondile. Gcwalisa isilinda sokulinganisa isampula bese uthela yonke impushana ezokalwa kufaneli, bese ukhipha intonga yokuvimba, ukuze impushana igelezele kusilinda sokulinganisa nge-outlet yokugeleza kwefaneli, lapho yonke impushana iphuma, khipha ukulinganisa. cylinder, uyikhuhle ibe isicaba nge-scraper futhi uyibeke esilinganisweni ukuze ukale.

Uma i-powder imanzi, idinga ukomiswa kusengaphambili. Indlela yokumisa ukomisa i-powder kuhhavini ngo-105 ° C. Uma kukhona udoti ku-powder, kuyadingeka ukususa udoti ngezikrini ezingu-80 zemeshi.
Isampula efanayo yokwenza izivivinyo ezintathu, thatha isilinganiso saso sesampula yemiphumela yokuminyana okuxekethile, kanye nokuhlolwa okuthathu okutholwe yimpushana yenani eliphakeme kanye nenani elincane lomehluko kufanele libe ngaphansi kuka-1g, ngaphandle kwalokho qhubeka nokuhlola, kuze kube yilapho kunesisindo esithathu senani eliphezulu nenani eliphansi lomehluko lingaphansi kuka-1g, kusetshenziswa idatha emithathu ukubala inani lokuminyana okuxekethile.

Phakathi kwazo:
ρh: ukuminyana okuxekethile;
V: Ivolumu (nansi i-100)
m1: Hlola ikhwalithi yesampula okokuqala ngqa
m2: Hlola ikhwalithi yesampula okwesibili
m3: Hlola ikhwalithi yesampula okwesithathu.

Amapharamitha wobuchwepheshe:
1. Ivolumu yesilinda sokulinganisa: 25cm3, 100cm3
2, indawo yokuvula ifaneli: 2.5mm, 5.0mm, noma 12.7mm
3, ukuphakama kwefaneli: 25mm, 115mm
4, itheyiphu yefaneli :60°
