Cov xim dab tsi yuav tsum nres cov xim?

Ib txwm tshiab cov kua dej xim

Tshiab glycol-raws li cov kua dej nres DOT-3, DOT-4 thiab DOT-5.1 yog qhov tseeb lossis muaj xim daj daj. Thiab cov xim no tsis yog ib txwm ntuj. Glycol alcohols tsis muaj xim. Ib feem ntawm cov kua ntxiv cov xim daj rau cov khoom ntxiv, ib feem ntawm cov xim muaj feem cuam tshuam.

DOT-5 thiab DOT-5.1/ABS brake fluids feem ntau yog xim liab lossis liab dawb. Nws kuj tsis yog xim ntuj ntawm silicones. Silicone-based kua yog tshwj xeeb tinted kom cov neeg tsav tsheb tsis txhob confuse lawv thiab sib tov nrog glycol. Kev sib xyaw ntawm glycol thiab silicone brakes yog qhov tsim nyog. Cov khoom no txawv ntawm ob qho tib si hauv paus thiab cov khoom siv ntxiv. Lawv kev sib cuam tshuam yuav ua rau stratification rau hauv feem thiab nag lossis daus.

Tag nrho cov dej nres, tsis hais lub hauv paus thiab cov xim ntxiv, nyob twj ywm pob tshab. Lub xub ntiag ntawm nag lossis daus matte qhia tias muaj kuab paug lossis tshuaj hloov pauv uas tau tshwm sim. Nyob rau hauv cov ntaub ntawv no, nws yog tsis yooj yim sua rau ncuav xws li kua rau hauv lub tank. Tsis tas li ntawd, nrog rau qhov hnyav hypothermia, cov kua yuav tau txais cov xim dawb me ntsis thiab tsis pom tseeb. Tab sis tom qab thawing, xws li kev hloov pauv hauv cov khoom zoo yog neutralized.

Muaj xws li cov lus dab neeg hais tias tom qab ob peb lub voj voog khov-thaw, cov dej nres tuaj yeem siv tsis tau. Qhov no tsis muaj tseeb. Cov additives thiab lub hauv paus raug xaiv nyob rau hauv xws li ib txoj kev uas txawm tias tom qab rov qab poob rau hauv qhov kub thiab txias mus rau hauv qab -40 ° C, lawv decomposition los yog degradation tsis tshwm sim. Tom qab thawing, cov kua yuav ua kom tag nrho nws cov xim qub thiab nws cov khoom ua haujlwm.

Glycols thiab silicones siv nyob rau hauv kev tsim cov dej nres yog cov kuab tshuaj zoo. Yog li ntawd, cov additives nyob rau hauv lawv tsis poob mus rau hauv ib tug pom precipitate txawm tom qab ib tug ntev lub sij hawm ntawm inactivity yam tsis sib tov. Peb pom cov pob zeb nyob hauv qab ntawm lub lauj kaub nrog cov dej nres - tsis txhob sau rau hauv lub cev. Feem ntau, nws tau tas sij hawm, los yog nws yog thawj zaug tsis zoo.

Yuav qhia li cas los ntawm cov xim uas yuav tsum tau hloov cov dej nres?

Muaj ntau lub cim qhia tias, tsis muaj cov cuab yeej tshwj xeeb, yuav qhia rau koj tias cov dej nres yog kev laus thiab poob nws cov khoom ua haujlwm.

1. Darkening tsis poob ntawm pob tshab. Xws li kev hloov ntawm cov xim yog txuam nrog kev loj hlob ntawm lub hauv paus thiab cov khoom siv ntxiv, nrog rau kev saturation nrog noo noo. Yog tias cov kua tsuas yog darkened, tab sis tsis poob ib co pob tshab, thiab tsis pom txawv txawv inclusions nyob rau hauv nws ntim, feem ntau nws tseem yuav siv tau. Nws yuav ua tau kom paub ntau meej tsuas yog tom qab kev soj ntsuam nrog ib tug tshwj xeeb ntaus ntawv: ib tug nres kua tester, uas yuav txiav txim seb cov feem pua ​​ntawm cov dej.
2. Poob pob tshab thiab cov tsos ntawm nplua inclusions thiab heterogeneous sediments nyob rau hauv ntim. Qhov no yog ib qho qhia meej tias cov dej nres tau khiav mus txog qhov txwv thiab yuav tsum tau hloov. Txawm hais tias tus neeg kuaj pom tias cov dej nyob hauv qhov qub, cov kua yuav tsum tau hloov. Txwv tsis pub, teeb meem yuav tshwm sim nyob rau hauv lub cev, raws li ib tug maub xim thiab heterogeneous inclusions qhia hnav ntawm cov additives.

Txawm hais tias cov dej nres tseem zoo li qub hauv cov xim, tab sis nws lub neej kev pabcuam tau tshaj 3 xyoo rau glycol bases thiab 5 xyoo rau silicone bases, koj yuav tsum tau hloov nws nyob rau hauv txhua rooj plaub. Thaum lub sijhawm no, txawm tias cov kev xaiv zoo tshaj plaws yuav saturated nrog noo noo thiab poob lawv cov lubricating thiab tiv thaiv cov khoom.
