Ungayifumana njani inqanaba lokunciphisa amanzi?

I-1. Umxholo wesihloko kunye nenqanaba lesicelo

Le ndlela ichaza izixhobo kunye namanyathelo okusebenza kokumiselwa kobuqhetseba bokuhombisa kwesamente.

Le ndlela isebenza kumiselo lodaka lwentaba-mlilo yentaba-mlilo yentaba-mlilo, iCortland yeCortland, i-Cortyland eqhelekileyo exutywe ne-volkanic Ash, i-Slag Portlands kunye nezinye iintlobo zesamente ezichongiweyo zokusebenzisa le ndlela.

2. Imigangatho yegama

Indlela yovavanyo lwe-GB177

I-GB178 isanti esemgangathweni yovavanyo lwamandla

I-JBW 01-1-1 Isampula esemgangathweni yolwelo lweSolity

I-3. Indlela yokuchonga yemigangatho yokunciphisa amanzi yodaka yile ilandelayo:

3.1 Izixhobo kunye nezixhobo

A. Umxube we-fer;

B. Itafile ye-Gumela (5mm i-5mm ipleyiti yeglasi kufuneka yongezwe);

C. I-Cylindrical bar ye-RAMMITRICRICRICRINAL: I-BIOST ye-ANTER, i-AMMER 20MM, ubude malunga ne-185mm;

D. I-STED ye-STEED ye-Pone i-Word kunye ne-Sund Cone Cone I-Word ye-7 ± 0.5mm, i-0.5mm, i-GOETER i-00 ± i-00 ± I-STEED ye-STED kunye ne-speen ye-STED yenziwa ngezinto zentsimbi;

E. Mbewu (ukulinganisa i-300mm) okanye i-calipers ngokulinganisa i-300mm;

F. Spatula.

G. Ibhalansi yeziyobisi (enobunzima be-1000g, imvakalelo ye-1G).

3.2. Inkqubo yovavanyo

3.2.1 Ukulinganisa ukusetyenziswa kwamanzi kodaka lwereferensi

A. Unobunzima be-300G yesamente kunye nesanti esemgangathweni ye-750g kwaye ubathuma kwimbiza yokuxuba, qala umxube, wongeza amanzi kancinci emva kokuxuba kwi-5s, kwaye wongeze ngaphakathi kwi-30s. Yekani ukuvuselela i-3min emva kokuqala umatshini. Hlukana nodaka kumabala kwaye ususe ipani eshukumisayo.

B. Ukuxuba udaka ngaxeshanye, ngetafile yetafile enamanzi, i-ramming rod, i-cut cut i-cone ijikeleze ipleyiti yeglasi, kwaye igubungele ilaphu leglasi, ligqunywe lilaphu elimanzi.

C. Udaka oluxubeneyo lukhawuleza wahluleke lababini lemingxunya, umaleko wokuqala ufakwe kwi-cone malunga ne-rams kwisithuba se-rams, efakwe kwi-rams esine-ramer, efakwe kwi-rom rom rhabaxa amashumi alishumi anesihlanu. Xa ulayisha isanti kunye ne-ramm, cofa i-trinyackete cone ufe ngesandla ukuthintela intshukumo.

D. Emva kokuthulula i-tamp, sebenzisa i-spatula ukuze uchithe udaka lodaka olungaphezulu kwe-cone ejikelezayo kwaye uyisule iflethi, emva koko nyuse ngobunono obujikelezile phezulu. Hlanganisa izandla ngesondo levili lenze itafile yokutsiba itsiba amashumi amathathu ngenqanaba lomzuzwana ngamnye.

E. Emva kokubetha i-calipers ukulinganisa ububanzi bobume bendawo yokuhlala, kwaye kuthathe ixabiso eliphakathi ledayili ezimbini, kwaye ichazwe kwi-mm. Xa i-Prerdo Translations I-140 ± 5mm, ukusetyenziswa kwamanzi kukutya kwamanzi kuluntu ekubonakalisweni.

3.2.2 Ngokutsho kwe-3.2.1 indlela, ukusetyenziswa kwamanzi kodaka nge-arhente encitshiswa kwamanzi kufikelela kwi-140 ± 5mm.

3.3. Iqondo lokunciphisa amanzi lodaka lokunyangwa libaliwe ngolu hlobo lulandelayo:

Iqondo lokunciphisa amanzi odaka (%) = (W0-W1) / w0 × 100

Phi, i-w0-i-W0 - Ukusetyenziswa kwamanzi (G) Xa ukungathobeki kodaka lwereferensi yi-140 ± 5mm;

I-W1 -Ukusetyenziswa kwamanzi (G) Xa imeko yokungaqhelekanga i-arhente enciphisa amanzi yi-140 ± 5mm.

Ixabiso lezinga lokunciphisa amanzi yixabiso le-Arithmetic lithetha iisampulu ezintathu.
