Zolakwitsa zofala kwambiri ndi zoletsa kuwuma

Bwanji osangokweza pamwamba ndi mitundu yomwe wopanga aliyense amalimbikitsa

Zomwe timadana nazo kuvomereza, chilimwe chitha ndipo ndi nthawi yokonzekeretsa magalimoto athu miyezi yozizira. Zomwe zimaphatikizaponso kuyang'ana momwe mumazizira. Koma pantchito yomwe ikuwoneka yosavuta iyi, mwatsoka, nthawi zambiri zolakwitsa zazikulu zimapangidwa.

Kodi ndingathe kuwonjezera zoletsa kuwuma?

M'mbuyomu, kubwezeretsanso antifreeze kunali ntchito yophweka, chifukwa msika wa ku Bulgaria unalibe chisankho, ndipo ngakhale pamene panali, aliyense anali ndi ndondomeko yofanana. Komabe, pakali pano sizili choncho nkomwe. Osachepera ma antifreeze atatu ogulitsa omwe ali osiyana kwambiri ndi mankhwala, osagwirizana wina ndi mzake - Ngati mukufuna kuwonjezera, muyenera kusamala kwambiri kuti mulowe muzolemba zoyenera. Kusakaniza mitundu iwiri yosiyana kungathe kuthetsa radiator ndi dongosolo lozizira.

Palinso chinthu china: pakapita nthawi, mankhwala omwe amapanga zoletsa kuwuma amataya katundu wawo. Chifukwa chake, kutengera mtundu, ziyenera kusinthidwa kwathunthu zaka ziwiri kapena zisanu zilizonse. Kudula kwanthawi yayitali kumatha kubweretsa madipoziti osafunikira pamapayipi ndi rediyeta.

Mitundu yayikulu yoletsa kuwuma

Pafupifupi mitundu yonse yamadzimadzi yoziziritsa ndi yankho la ethylene glycol (kapena, monga masiku ano, propylene glycol) ndi madzi. Kusiyanitsa kwakukulu ndiko kuwonjezera kwa "corrosion inhibitors", i.e. zinthu zomwe zimateteza radiator ndi dongosolo ku dzimbiri.

Panthawiyo, zakumwa zamtundu wa IAT zimakhala zambiri, zomwe zimakhala ndi ma inorganic acid monga corrosion inhibitors - choyamba ma phosphates, ndiyeno, chifukwa cha chilengedwe, silicates. Kwa izi, magalimoto opitilira zaka 10-15 nthawi zambiri amasinthidwa. Komabe, antifreeze ya IAT imatha pafupifupi zaka ziwiri kenako iyenera kusinthidwa.

Magalimoto amakono amasinthidwa kukhala antifreeze mtundu wa OAT, momwe ma silicates amasinthidwa ndi azoles (mamolekyu ovuta okhala ndi maatomu a nayitrogeni) ndi ma organic acid monga zoletsa dzimbiri. Amakhala olimba - nthawi zambiri mpaka zaka zisanu.

Palinso otchedwa. HOAT kapena madzi a haibridi, omwe amaphatikizira mitundu iwiri yoyambirira ndi ma silicates ndi ma nitrites nthawi yomweyo. Ma Carboxylates amaphatikizidwanso m'mawonekedwe ovomerezeka a EU. Amakhala oyenera kuzinthu zowopsa kwambiri, koma amakhala ndi nthawi yayitali ndipo amafunikira kuwongolera pafupipafupi.

Iliyonse ya mitundu itatu siyigwirizana ndi inayo.

Kodi tingawasiyanitse ndi mtundu wawo?

Ayi. Mtundu wa antifreeze umadalira utoto wowonjezera, osati pamankhwala ake. Opanga ena amagwiritsa ntchito mtundu kusonyeza mtundu—mwachitsanzo, wobiriwira wa IAT, wofiira kwa OAT, lalanje wa HOAT. M'Chijapani antifreeze, mtunduwo umasonyeza kutentha kwake. Ena amagwiritsa ntchito mitundu mosasankha, choncho nthawi zonse werengani chizindikirocho.

Ena opanga amagwiritsa ntchito mawu akuti "coolant" ndi "antifreeze" mosiyana. Kwa ena, zoziziritsa kuziziritsa zili kale madzimadzi osungunuka, okonzeka kugwiritsidwa ntchito, ndipo antifreeze amatchedwa undiluted concentrate.

Ndi madzi ochuluka motani komanso otani?

Akatswiri amalangiza mwamphamvu kuwonjezera madzi osungunuka, chifukwa pali zonyansa zambiri m'madzi wamba zomwe zimayikidwa pamakoma a mapaipi ndi radiator. Kuchuluka kwa dilution kumadalira mtundu weniweni wa antifreeze ndi momwe mungakhalire mukugwiritsa ntchito - kutentha kochepa kumafuna kuzizira kocheperako.

Kodi ndizofunikira kutsatira zofunikira za wopanga?

Pafupifupi aliyense wopanga magalimoto amalimbikitsa mtundu winawake, kapena mtundu winawake wa antifreeze. Ambiri amaganiza kuti iyi ndi njira yoti makampani azigwedeza chikwama chanu, ndipo sitikuwadzudzula. Koma nthawi zambiri pamakhala malingaliro okwanira pamawuwo. Njira zamakono zoziziritsira zimakhala zovuta kwambiri ndipo nthawi zambiri zimapangidwira magawo ena a ma antifreeze. Ndipo kuyesa kuyanjana ndi mitundu ina yamadzi kumakhala kovuta, kotenga nthawi komanso kotsika mtengo, motero opanga nthawi zambiri amapewa. Amalamula zakumwa zonse zofunika kwa kontrakitala wawo kenako amaumiriza kuti makasitomalawo azigwiritsa ntchito.
