Kodi pali kusiyana kotani pakati pa antifreeze ndi antifreeze? Chabwino nchiyani? Kodi angasakanizidwe?

Tikagula galimoto, timafuna kuti ikhale yaitali momwe tingathere. Moyo wautumiki umadalira makamaka momwe ntchito ikugwirira ntchito komanso ubwino wa utumiki.

Madzi aukadaulo amakhudza kwambiri magwiridwe antchito a machitidwe onse a injini. Udindo wofunikira umaseweredwa ndi dongosolo lozizira, chifukwa chomwe injini imasunga kutentha komwe kumafunikira.

Ngati m'mbuyomo, kumayambiriro kwa mafakitale agalimoto, injini zamagalimoto zidapangidwa ndi chitsulo chosungunula ndi mkuwa, ndiye kuti ma radiator amatha kuthiridwa madzi wamba osungunuka. Ndipo m'nyengo yozizira, ethylene glycol kapena mowa adawonjezeredwa kumadzi awa kuti ayezi asapangidwe mu radiator. Komabe, kwa magalimoto amakono, kusakaniza koteroko kudzakhala ngati imfa, chifukwa kudzayambitsa njira zowonongeka mkati mwa injini. Choncho akatswiri a zamankhwala anayamba kufunafuna madzi amene sangawononge zitsulo.

Umu ndi momwe antifreeze yamagalimoto idapangidwira. Maphunziro ofananirako adachitika ku Soviet Union, komwe m'ma 70 adakwanitsa kupeza chilinganizo chawo choletsa kuzizira - Tosol.

Kuchokera apa tikhoza kupeza mfundo zotsatirazi:

• antifreeze ndi antifreeze ndi zakumwa zomwe sizimaundana pakatentha kwambiri;
• antifreeze - dzina limagwiritsidwa ntchito padziko lonse lapansi;
• antifreeze ndi mankhwala achi Russia okha omwe amapangidwira magalimoto opangidwa ku USSR ndi Russia yamakono.

Kusiyana kwakukulu kwa mankhwala

Kusiyana kofunikira kwambiri ndi zomwe zinthu zimaphatikizidwa mu antifreeze ndi antifreeze.

Antifreeze ili ndi zigawo zikuluzikulu - madzi ndi anti-freeze additive ethylene glycol. Madzi amagwiritsidwa ntchito popereka mankhwalawa kuzinthu zonse za injini; ethylene glycol imalepheretsa madzi kuzizira pakatentha kwambiri. Mulinso mchere wa inorganic zidulo. - ma phosphates, nitrates, silicates, omwe amapangidwa kuti ateteze zitsulo kuti zisawonongeke. Kalasi ya antifreeze imadalira momwe mchere wa asidi umagwiritsidwa ntchito komanso kuchuluka kwa zowonjezera zosazizira - ndiko kuti, kuchepetsa kutentha kwa kuzizira.

Antifreeze imapangidwanso ndi madzi ndi ethylene glycol. Glycerin ndi mowa waukadaulo amawonjezedwa kwa iwo (ndicho chifukwa chake simungamwe antifreeze). Koma kusiyana kofunikira kwambiri ndikuti kulibe mchere wazinthu zopanda organic mu antifreeze; organic mcherezomwe zimathandizira kwambiri magwiridwe ake.

Mfundo yogwirira ntchito

Popeza chitsulo chilichonse chimawopa kukhudzana ndi madzi, onse antifreeze ndi antifreeze amapanga wosanjikiza woonda woteteza pamwamba pa zitsulo za injini ndi dongosolo lozizira lomwe limalepheretsa kukhudzana pakati pa madzi ndi chitsulo. Komabe, pali zosiyana zina mwa izi.

Antifreeze imazungulira mu dongosolo ndikupanga filimu yopyapyala theka la millimeter wandiweyani pazitsulo zonse zamkati. Chifukwa cha filimuyi, kutentha kwa kutentha kumasokonezeka, motero, injini imafunikira mafuta ambiri. Ichi ndi chimodzi mwa zifukwa zomwe mafuta amachulukira m'nyengo yozizira, takhudza kale mutuwu pa Vodi.su yathu ya autoportal.

Kukhalapo kwa mchere wa silicate ndi nitrite kumapangitsa kuti ayambe kuphulika, gel osakaniza ngati slurry amapangidwa, omwe pang'onopang'ono amatseka ma cell a radiator.

Antifreeze iyenera kusinthidwa nthawi zambiri - makilomita 40-50 aliwonse, sangatenge nthawi yaitali, chifukwa filimu yotetezera imawonongedwa chifukwa cha kutentha kwakukulu ndipo injini ikuwopsezedwa ndi dzimbiri. Antifreeze imayamba kuwira pa kutentha pamwamba pa 105-110 madigiri.

Antifreeze imagwira ntchito mofananamo, koma ndi kusiyana komwe filimu yotetezera ikuwonekera pa zinthu zomwe zimawonongeka ndi dzimbiri, motero, mafuta a madalaivala omwe amatsanulira antifreeze sakuwonjezeka kwambiri. Komanso, antifreeze sapereka mpweya wotere, sichiyenera kusinthidwa kawirikawiri, madzi samataya katundu wake ndi kuthamanga kwa makilomita oposa 200 zikwi. Mukawiritsa, antifreeze samapanga thovu ndi ma flakes omwe amatseka radiator. Inde, ndipo amaphika pa kutentha kwa madigiri 115.

Ndiye kuti, tikuwona kuti ngati musankha pakati pa antifreeze ndi antifreeze, ndiye kuti zokonda ziyenera kuperekedwa kwa omaliza.

Koma chinthu choterocho monga mtengo wake umamutsutsa - chitini cha 5-lita cha antifreeze chimawononga khobiri, pamene ndalama zambiri ziyenera kulipidwa kwa antifreeze.

Zowona, pali zabodza zambiri pamsika uwu: ngati muwona zolembedwa ngati "Antifreeze-Silicate", kapena "Antifreeze-Tosol", ndiye funsani mlangizi kusiyana kwakukulu pakati pa antifreeze ndi antifreeze - mchere wa organic ndi inorganic acid.

Ma silicates ndi gulu lalikulu la mchere lomwe silingakhale logwirizana ndi zinthu zachilengedwe, ndiye kuti, akuyesera kukugulitsani antifreeze potengera antifreeze.

Kumbukiraninso kuti antifreeze safunikira kuchepetsedwa ndi madzi osungunuka. Kutentha kwake kozizira nthawi zambiri kumakhala m'derali kuyambira 15 mpaka 24-36 digiri. Komano, antifreeze ikhoza kugulitsidwa mu mawonekedwe a okonzeka okonzeka osakaniza ndi mu mawonekedwe a concentrate. Ngati mugula antifreeze woyikirapo, ndiye kuti iyenera kuchepetsedwa mu chiŵerengero chimodzi-mmodzi, momwemo kuzizira kumakhala madigiri -40.

Antifreeze sikoyenera kugula magalimoto opangidwa kunja. Mwachitsanzo, Toyota imatsanulira antifreeze yofiira.

Mutha kusakaniza antifreeze yamtundu womwewo, musasakanize antifreeze ndi antifreeze. Musanawonjezere antifreeze, zotsalira zonse zam'mbuyomu ziyenera kutsanulidwa.

Kuti makinawo azikhala motalika momwe angathere popanda kuwonongeka, gulani mitundu yokha ya antifreeze kapena antifreeze yomwe ikulimbikitsidwa ndi wopanga.
