Cov yam ntxwv ntawm Antifreeze A-40
Nta
Zoo li lwm yam coolants ntawm ib tug zoo sib xws (piv txwv li, antifreeze A-65), A-40 muaj xws li, ntxiv rau ethylene glycol, ntau yam additives:
- Antifoam.
- Inhibiting txheej txheem corrosion.
- Xim (xiav dye feem ntau siv, tab sis koj tuaj yeem pom Antifreeze A-40 hauv liab ntawm muag).
Nyob rau hauv Soviet lub sij hawm, thaum cov khoom twb xub synthesized, tsis muaj leej twg koom nyob rau hauv kev sau npe ntawm lub npe, yog li ntawd, nyob rau hauv niaj hnub tshwj xeeb khw muag khoom, koj muaj peev xwm nrhiav tau ib tug txaus tus naj npawb ntawm zoo sib xws hom uas tsim los ntawm txawv manufacturers.
Cov yam ntxwv ntawm lub cev tiv thaiv kab mob, uas ua raws li cov kev cai ntawm GOST 28084-89 thiab TU 2422-022-51140047-00, yog raws li hauv qab no:
- Crystallization pib kub, ºC, tsis tsawg: -40.
- thermal stability, ºC, tsis tsawg: +120.
- Qhov ceev, kg / m3 -1100.
- pH ntsuas - 8,5 .... 9,5.
- Thaum tshav kub kub muaj peev xwm ntawm 0ºC, kJ / kg K - 3,19.
Feem ntau ntawm cov ntsuas tau piav qhia yog txiav txim siab los ntawm qhov concentration ntawm ethylene glycol nyob rau hauv cov ntsiab lus ntawm Tosol A-40, nws viscosity thiab ib qho kub ntawm cov coolant, uas yog teem thaum lub sij hawm lub cav ua hauj lwm. Tshwj xeeb, dynamic viscosity ntawm cov khoom yog li ntawm 9 cSt ntawm 0ºC, mus txog 100 cSt ntawm -40ºC. Raws li qhov muab qhov kub thiab txias, nws muaj peev xwm xyaum tsim kom muaj qhov zoo ntawm cov khoom tiv thaiv khov.
Yuav ua li cas los xyuas qhov zoo ntawm Antifreeze A-40?
Rau cov tswv tsheb, qhov kev ntsuam xyuas kom haum rau lub coolant yog qhov yooj yim tshaj plaws los ua ntawm cov ntsiab lus hauv qab no:
- Kev ntsuas ceev: qhov ntau nws txawv ntawm tus qauv tus nqi, qhov phem dua. Ib qho kev txo qis qhia tau hais tias cov khoom muaj ethylene glycol, uas yog diluted nrog dej ntau dhau.
- Kev txiav txim siab ntawm qhov tseeb alkalinity pH ntawm cov tshuaj: ntawm nws cov nqi qis, cov khoom tiv thaiv corrosion ntawm cov khoom muaj pes tsawg leeg deteriorate heev. Qhov no tshwj xeeb tshaj yog tsis zoo rau lub cav qhov chaw uas yog ua los ntawm txhuas.
- Raws li lub uniformity thiab siv ntawm cov xim: yog hais tias nws yog lub teeb bluish, los yog, conversely, tsaus nti, muaj pes tsawg leeg yog feem ntau yuav ua tau ntev dhau los, thiab tau poob ib tug xov tooj ntawm nws cov txiaj ntsig zoo.
- Kuaj rau crystallization ntawm qhov kub thiab txias. Yog tias Antifreeze A-40 tsis hloov nws lub ntim thaum khov thaum tsis muaj cua, ces koj muaj cov khoom zoo;
- Thermal stability test, uas ib tug npaum li cas ntawm coolant yog coj mus rau boil, tom qab uas nws yog sab laug rau boil tshaj tsawg tshav kub rau ob peb feeb. Nyob rau tib lub sijhawm, qhov tsis hnov tsw ntawm ammonia yuav tsum tsis txhob hnov, thiab cov kua hauv lub khob tseem pob tshab, tsis tso cov dej nag hauv qab.
Tag nrho cov kev ntsuam xyuas saum toj no tuaj yeem ua tau yam tsis muaj kev yuav khoom tshwj xeeb.
nqi ntawm
Ntawm tus nqi ntawm Antifreeze hom A-40 lossis A-40M, koj tuaj yeem tsim tsis tau tsuas yog kev ntseeg siab ntawm cov chaw tsim khoom, tab sis kuj yog qhov zoo ntawm cov coolant. Cov tuam txhab loj ntim cov tshuaj tiv thaiv kab mob hauv cov thawv ntawm ntau lub peev xwm thiab tsim cov khoom lag luam hauv cov khoom loj loj. Yog li ntawd, tus nqi yuav qis dua qhov nruab nrab me ntsis (tab sis tsis yog los ntawm ntau!). Random, tsis yog cov tuam txhab tshwj xeeb hauv qab lub npe "Tosol A-40" tuaj yeem tsim cov khoom cuav li niaj zaus - ethylene glycol diluted nrog dej (lossis txawm tias pheej yig dua tab sis muaj tshuaj lom methylene glycol), uas muaj qee yam khoom noj xiav dyes ntxiv. Tus nqi ntawm xws li pseudotosol yuav qis dua.
Nyob ntawm seb hom ntim ntim, chaw tsim khoom thiab thaj chaw muag khoom, tus nqi ntawm Antifreeze A-40 sib txawv hauv cov kev txwv hauv qab no:
- Rau ntim 5 l - 360 ... 370 rubles.
- Rau ntim 10 l - 700 ... 750 rubles.
- Rau ntim 20 l - 1400 ... 1500 rubles.
Thaum packing nyob rau hauv 220 l steel chim, cov khoom nqi pib ntawm 15000 rubles.
