Kev sib xyaw thiab cov yam ntxwv ntawm cov kua dej nres DOT-4
DOT-4 brake kua yog 98% polyglycols. Qhov seem 2% yog additives.
Nws yog ib qho tseem ceeb kom nkag siab tias muaj ib qho qauv uas tswj cov khoom sib xyaw ntawm cov kua dej nres. Tus qauv no yog tsim thiab tswj los ntawm US Department of Transportation. Thiab txhua yam kua, tsis hais txog ntawm cov chaw tsim khoom, nyob rau hauv txoj kev xav yuav tsum ua raws li cov yam ntxwv ntawm tus qauv, yog tias nws yog tsev neeg DOT.

Muaj ob peb yam kev tswj hwm. Ua ntej, nws yog lub hauv paus. Lub hauv paus DOT-4 yog cov dej cawv ntau, uas yog hu ua polyglycols. Cov cawv no muaj lubricity zoo, tsis muaj zog kiag li, nyob twj ywm ua haujlwm mus rau -42 ° C ntawm qhov nruab nrab, thiab boil ntawm qhov kub tsis qis dua + 230 ° C. Tsis tas li ntawd, tag nrho cov cawv ntawm cov pab pawg glycol yog tus cwj pwm los ntawm hygroscopicity - lub peev xwm nqus dej los ntawm ib puag ncig thiab yaj dej hauv nws qhov ntim yam tsis muaj sediment.
Qhov thib ob, nws yog ib pob ntawm additives. Additives txhim kho cov khoom ua haujlwm ntawm cov kua dej. Cov muaj pes tsawg leeg ntawm additives kuj raug tswj. Thiab ob qho tib si hauv qualitative thiab quantitative cov ntsiab lus.
Qhov no txhais tau hais tias yog tias koj yuav cov dej nres uas sau npe DOT-4, ces nws tau lees tias muaj qhov tsawg kawg nkaus ntawm cov khoom uas ua kom nws txoj haujlwm tsis pub dhau qhov txwv uas tau teev tseg los ntawm tus qauv.
Txawm li cas los xij, txoj cai tso cai rau qhov sib ntxiv ntawm cov khoom thib peb lossis qhov nce ntawm qhov sib faib (tsis yog qhov txo qis), uas tuaj yeem hloov pauv qee yam ntawm cov dej nres. Feem ntau rau qhov zoo dua. Piv txwv li, lawv txo qhov kub thiab txias viscosity, nce qhov kub thiab txias, lossis ua kom cov kua dej tsis zoo rau cov txheej txheem ntawm absorbing noo noo los ntawm huab cua.
Manufacturers ntawm ib nrais muag
Kev ua lag luam niaj hnub no muaj ntau ntxiv nrog cov khoom siv ntawm DOT-4 chav dej nres. Cia peb saib ob peb yam khoom uas paub zoo hauv kev nce qib ntawm tus nqi, pib nrog qhov pheej yig tshaj.
