Kodi brake fluid imayaka?
Kodi glycol brake fluid imayaka?
Ma brake system amagalimoto ambiri amadzazidwa ndi glycol brake fluid ya mtundu wa DOT-3, DOT-4 kapena DOT 5.1. Mankhwalawa ndi oposa 90% glycols ndi polyglycols. Zina zonse za voliyumu yonse zimakhala ndi zowonjezera zomwe zimawonjezera magwiridwe antchito a brake fluid.
Glycols ndi mowa wa dihydric. Monga zakumwa zonse zamagulu a mowa, ma glycols amagawana zambiri mwazinthu zawo. Kuphatikiziranso kuthekera kosunga kuyaka kosagwirizana pambuyo poyatsa, popanda kulandira mphamvu yotentha kuchokera kunja. Izi zikutanthauza kuti brake fluid ikangoyaka, imayaka mpaka ipse. Panthawi imodzimodziyo, sikoyenera kutenthetsa kuti ipitirize kuyaka.
Kutentha kwa kutentha kwa brake fluid muzochitika zilizonse ndizosiyana. Zimasiyanasiyana kutengera mtundu weniweni wa brake fluid. Komabe, lawi wamba lotseguka lamtundu uliwonse (kuchokera ku machesi, chowotcha gasi, kapena mafuta oyaka a hydrocarbon) ndikwanira kuyambitsa kuyatsa kwa glycol brake fluid.
Mabuleki amadzimadzi samayaka atangokumana ndi lawi lotseguka. Ndiye kuti, madziwa sali m'gulu la zoyaka. Wangotentha.
Zopangidwa ndi kuyaka kwa brake fluid ndi hydrocarbon oxides, carbon dioxide ndi carbon monoxide, komanso mpweya wamadzi. Ma precipitates ochepa a gawo lolimba amakhalabe, ndipo amakhala ovunda pazinthu zowonjezera.
Kodi silicone brake fluid imayaka?
Silicone brake fluids a kalasi ya DOT-5 sali ambiri m'magalimoto amakono monga glycolic. Chowonadi ndi chakuti amafunikira zipangizo zapadera pakupanga dongosolo lokha, ndi katundu wosiyana. Ndiye kuti, ndizosatheka kutsanulira silikoni DOT-5 mu thanki ya brake system yopangidwira madzi a glycol.
Zamadzimadzi za silicone, monga dzina limatanthawuzira, zimachokera ku silicones. Chiŵerengero cha maziko ndi zowonjezera ndi zofanana ndi za glycol brake fluids: 9 mpaka 1.
Silicone ili ndi maziko a silicon. Kukhalapo kwa okosijeni mu kapangidwe ka mankhwala amalola kuti zakumwa za silikoni ziziyaka mokhazikika pambuyo poyatsira. Koma monga mitundu ya glycol ya DOT-3 ndi DOT-4, madzi a silikoni samayaka nthawi yomweyo akakumana ndi moto. Zimatenga nthawi kuloza lawi lotseguka kumadzimadzi a silikoni a DOT-5 kuti ayatse ndikupitiriza kuyaka okha.
Choyaka moto cha silikoni brake fluid ndi olimba silicon oxides ndi pang'ono kuwala wa hydrogen ndi carbon mankhwala.
Mwachidziwitso, madzimadzi a silikoni amawotcha "mwamphamvu" kuposa glycol.
