Brake fluid. Zotsatira zowopsa za mayeso

Malinga ndi kafukufuku wa Automotive Institute, anayi mwa khumi mwa khumi a DOT-4 ma brake fluids samakwaniritsa mfundo zina. Kutsika kwamadzimadzi kumatalikirana, ndipo zikavuta kwambiri kumatha kulepheretsa galimotoyo kutha kutsika.

The Materials Science Center ya Institute of Road Transport idayesa mtundu wamadzimadzi amtundu wa DOT-4 omwe amadziwika pamsika waku Poland. Kusanthula kwamakhalidwe kumakhudza zinthu khumi zodziwika bwino zamagalimoto. Akatswiri a ITS adayang'ana, kuphatikizapo mtengo wowira ndi kukhuthala, i.e. magawo amene kudziwa khalidwe la madzi.

- Zotsatira zoyesa zidawonetsa kuti madzi anayi mwa khumi samakwaniritsa zofunikira zomwe zafotokozedwa muyeso. Zinayi zakumwa anasonyeza kuti kuwira mfundo anali otsika kwambiri, ndipo awiri a iwo pafupifupi kwathunthu chamunthuyo pa mayeso ndipo sanasonyeze kukana makutidwe ndi okosijeni. M’malo mwawo, maenje a dzimbiri ankaonekeranso pa zinthu za m’ma labotale,” akufotokoza motero Eva Rostek, mkulu wa bungwe la ITS Materials Research Center.

M'malo mwake, kugwiritsa ntchito mabuleki otere (osavomerezeka) kumatha kukulitsa mtunda ndipo, zikafika povuta, kumapangitsa kuti galimoto iyimike.

Mabuleki amadzimadzi amataya katundu wake ndi zaka, kotero opanga magalimoto amalangiza kuti asinthe kamodzi pazaka ziwiri kapena zitatu. Ngakhale izi, kafukufuku mu 2014 anasonyeza kuti 22 peresenti ya Madalaivala a ku Poland sanalowe m’malo mwake, ndipo 27 peresenti anatero. kufufuzidwa magalimoto, iye anali ndi ufulu kusintha mwamsanga.

- Tiyenera kukumbukira kuti brake fluid ndi hygroscopic, i.e. zimatenga madzi kuchokera ku chilengedwe. Kuchepa kwa madzi, kumapangitsa kuti pakhale zotentha kwambiri komanso kuti ntchitoyo ikhale yabwino. Malo otentha amadzimadzi amtundu wa DOT-4 sayenera kukhala pansi pa 230 ° C, ndipo madzi amtundu wa DOT-5 sayenera kukhala osachepera 260 ° C, amakumbutsa Eva Rostek kuchokera ku ITS.

Mabuleki ogwira mtima okhala ndi madzimadzi apamwamba kwambiri pamakina amafikira kuthekera kwawo pafupifupi masekondi 0,2. Pochita izi, izi zikutanthauza (kungoganiza kuti galimoto yoyenda pa 100 km / h imayenda mtunda wa 27 m / s) kuti braking sikuyamba mpaka 5 metres pambuyo pa brake. Ndi madzimadzi omwe sagwirizana ndi magawo ofunikira, mtunda wa braking udzakwera mpaka nthawi 7,5, ndipo galimotoyo imayamba kutsika pang'onopang'ono mamita 35 kuchokera pamene mukukakamiza brake pedal!

Ubwino wa brake fluid umakhudza mwachindunji chitetezo chagalimoto, kotero posankha, tsatirani malingaliro a opanga magalimoto ndikugula zomata zosindikizidwa zokha.
