Amazi ya Viscous akeneye tekinike yihariye yo kuvoma

Wakatiye Uwitekaumuyoboromugihe cyo gusya glycerol? Nabikoze mugihe cya PhD, ariko nagombaga kumenya ko ibyo byongera ubusobanuro budasobanutse neza. Kandi mvugishije ukuri iyo nagabanije inama, nashoboraga no gusuka glycerol mu icupa mu muyoboro. Nahinduye tekinike yanjye kugirango ndusheho kunoza ibisubizo no kubona ibisubizo byizewe kandi byororoka mugihe nkorana namazi meza.

Icyiciro cyamazi gikeneye kwitabwaho cyane mugihe imiyoboro ari amazi meza. Ibi bikunze gukoreshwa muri laboratoire, haba muburyo bwiza cyangwa nkibigize buffer. Abazwi cyane bahagarariye amazi ya viscous muri laboratoire yubushakashatsi ni glycerol, Triton X-100 na Tween® 20. Ariko kandi, laboratoire zikora neza ubuziranenge bwibiryo, amavuta yo kwisiga, imiti n’ibindi bicuruzwa by’umuguzi bikemura ibibazo bya buri munsi.

Viscosity ivugwa nkigikorwa cyingirakamaro, cyangwa kinematike. Muri iki kiganiro ndibanda cyane ku mikorere ya viscosity ya fluid kuva isobanura urujya n'uruza rw'amazi. Urwego rwo kwiyegeranya rwerekanwe muri milipasikali ku isegonda (mPa * s). Ahubwo urugero rwamazi hafi 200 mPa * s nka 85% glycerol irashobora kwimurwa hifashishijwe imiyoboro isanzwe ya cushion. Iyo ukoresheje tekinike idasanzwe, guhinduranya imiyoboro, ibyifuzo byumwuka mwinshi cyangwa ibisigara mumutwe biragabanuka cyane kandi biganisha kubisubizo byukuri. Ariko na none, ntabwo aribyiza dushobora gukora kugirango tunonosore imiyoboro y'amazi meza (reba ishusho 1).

Iyo ubukonje bwiyongereye, ingorane ziriyongera. Hagati ya viscous ibisubizo bigera kuri 1.000 mPa * s biragoye kwimurwa ukoresheje imiyoboro isanzwe ya air-cushion. Bitewe no guterana kwimbere kwimbere ya molekile, amazi ya viscous afite imyitwarire itinda cyane kandi imiyoboro igomba gukorwa gahoro gahoro kandi neza. Tekinike ihinduranya tekinike ntabwo ihagije kugirango ihererekanyabubasha ryukuri kandi abantu benshi bapima ingero zabo. Izi ngamba nazo zisobanura kuzirikana ubwinshi bwamazi hamwe nuburyo laboratoire imeze nkubushuhe nubushuhe kugirango ubare neza ingano y'amazi akenewe muburemere. Kubwibyo, ibindi bikoresho byo kuvoma, byitwa ibikoresho byiza byo kwimura, birasabwa. Ibi bifite inama hamwe na piston ihuriweho, kimwe na syringe. Kubwibyo, amazi arashobora kwifuzwa byoroshye kandi agatangwa mugihe itangwa ryukuri ryatanzwe. Tekinike idasanzwe ntabwo ikenewe.

Nubwo bimeze bityo ariko, ibikoresho byiza byo kwimura bigera kumupaka hamwe nibisubizo bigaragara cyane nkubuki bwamazi, amavuta yuruhu cyangwa amavuta yubukanishi. Aya mazi asabwa cyane akeneye ikindi gikoresho kidasanzwe nacyo gikoresha ihame ryiza ryimurwa ariko byongeye kandi rifite igishushanyo mbonera cyo gukemura ibisubizo biboneka cyane. Iki gikoresho kidasanzwe cyagereranijwe ninama zisanzwe zo kwimura abantu kugirango babone urwego aho ari ngombwa ko uhindura kuva muburyo busanzwe bwo gutanga ukajya kumpanuro yihariye kubisubizo biboneye cyane. Byerekanwe ko ubunyangamugayo bwiyongera kandi imbaraga zikenewe mu kwifuza no gutanga ziragabanuka iyo ukoresheje inama idasanzwe kumazi meza cyane. Kubindi bisobanuro birambuye hamwe ningero zamazi, nyamuneka kura Applicaton Icyitonderwa 376 kumikorere myiza kumazi meza cyane.
