nres disc
Dimensions: tus piv Di/d ntawm sab nraud txoj kab uas hla ntawm lub dav hlau nres disc rau txoj kab uas hla ntawm lub ntug, pem hauv ntej log: {{0}}.45 ~ 0.70 , rear log 0.45 ~ 0.5
Khoom siv: 2Cr13
Kev kho cua sov: siab zaus quenching (HRC36 ± 3)
Kev ua haujlwm zoo: qhov ua haujlwm ntawm qhov chaw ua haujlwm ntawm lub nres nres yog tsawg dua {{0}}.1MM, thiab qhov sib npaug ntawm ob qhov chaw sib txhuam yuav tsum tsawg dua 0.08MM
brake kua
Brake fluid yog cov khoom siv hluavtaws ua los ntawm cov dej cawv ether ua cov kua hauv paus thiab ntxiv cov khoom ntxiv xws li tshuaj tiv thaiv oxidation, tiv thaiv corrosion thiab tiv thaiv xeb.
Feem ntau siv yog DOT3, DOT4, DOT5
Cov kua nplaum yuav tsum muaj cov yam ntxwv hauv qab no:
1. Kub kub taw tes. Qhov kub boiling point yog lub ntsiab feature. Yog tias qhov kub ntawm cov dej nres ntau tshaj qhov kub ntawm qhov kub, cov npuas yuav raug tsim tawm, ua rau nres nres.
2. Viscosity hloov me ntsis nrog kub. Lub nres yuav tsum ua haujlwm ib txwm nyob ntawm qhov kub ntawm -40 ~ 100 degree, yog li nws yuav tsum tau ua kom lub viscosity ntawm cov dej nres hloov me ntsis nrog rau qhov kub thiab txias ntawm qhov kub thiab txias. Yog tias qhov viscosity tsawg dhau, qhov kev sib khi ntawm tus nres yuav ua rau tsis zoo thiab ua rau cov dej ntws tawm; Yog hais tias lub viscosity siab dhau lawm, tus nres yuav tsis teb.
3. Kev ua haujlwm zoo lubrication. Txij li thaum lub nres yuav tsum tau ua hauj lwm ntev, yog hais tias lub lubrication kev ua tau zoo tsis zoo, lub hnav ntawm lub nres yuav ceev.
4. Cov khoom siv tshuaj ruaj khov. Yuav tsum tsis muaj tshuaj lom neeg cov tshuaj tiv thaiv ntawm cov dej nres thiab ntau yam xov xwm hauv kev sib cuag.
5. Tsawg hygroscopicity. Vim tias cov dej vaporization tsis tshua muaj, yog tias cov kua nres muaj hygroscopicity siab thiab sib xyaw nrog qee cov dej, cov npuas yuav tsim tawm thaum cov dej vaporizes, uas yuav cuam tshuam rau kev ua haujlwm ntawm braking.
Nres dej yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm QC/T 670-2000
