Kodi ndingasakaniza G11 ndi G12 antifreeze?

Antifreeze G11 ndi G12. Kodi pali kusiyana kotani?

Zozizira zambiri (zozizira) zamagalimoto wamba zimapangidwa pamaziko a dihydric alcohols, ethylene kapena propylene glycols, ndi madzi osungunuka. Madzi ndi mowa zimapanga zoposa 90% za antifreeze yonse. Komanso, kuchuluka kwa zigawo ziwirizi kungasiyane kutengera kuzizira kofunikira kwa choziziritsira. Ena onse a antifreeze amakhala ndi zowonjezera.

G11 antifreeze, monga Tosol wathunthu wapakhomo, ilinso ndi ethylene glycol ndi madzi. Ma antifreezes awa amagwiritsa ntchito mankhwala osokoneza bongo, ma phosphates osiyanasiyana, borates, silicates ndi zigawo zina monga zowonjezera. Ma organic compounds amachita patsogolo pamapindikira: patangotha ​​​​maola ochepa atadzaza dongosolo, amapanga filimu yoteteza pamakoma a dera lonse lozizira. Firimuyi imachotsa zotsatira zaukali za mowa ndi madzi. Komabe, chifukwa cha kusanjikiza kowonjezera pakati pa jekete yozizira ndi choziziritsa kuzizira, kutulutsa kutentha kumachepa. Komanso, moyo wautumiki wa G11 antifreezes wokhala ndi zowonjezera zokhala ndi inorganic ndi waufupi ndipo pafupifupi zaka 3 pazogulitsa zabwino.

G12 antifreeze imapangidwanso kuchokera ku madzi osakaniza ndi ethylene glycol. Komabe, zowonjezera zomwe zilimo ndi organic. Momwemo, gawo lalikulu loteteza motsutsana ndi nkhanza za ethylene glycol mu G12 antifreeze ndi carboxylic acid. Zowonjezera za organic carboxylate sizipanga filimu yofanana, kuti mphamvu yakuchotsa kutentha isagwe. Mankhwala a carboxylate amachita molunjika, makamaka pamalo owonongeka atawonekera. Izi penapake amachepetsa zoteteza katundu, koma sizimakhudza thermodynamic zimatha madzi. Nthawi yomweyo, antifreezes wotere amagwira ntchito pafupifupi zaka 5.

G12+ ndi G12++ antifreezes ali ndi organic ndi inorganic zowonjezera. Panthawi imodzimodziyo, pali zowonjezera zochepa za inorganic zomwe zimapanga wosanjikiza wotsekereza kutentha muzozizirazi. Choncho, G12 + ndi G12 ++ antifreezes pafupifupi sizimasokoneza kuchotsa kutentha ndipo nthawi yomweyo zimakhala ndi madigiri awiri a chitetezo.

Kodi antifreeze G11 ndi G12 angasakanizidwe?

Mutha kusakaniza G11 ndi G12 antifreeze muzochitika zitatu.

1. M'malo mwa G11 antifreeze yovomerezeka, mutha kudzaza momasuka choziziritsa cha kalasi ya G12 ++, komanso kusakaniza zoziziritsira ziwirizi mulingo uliwonse. Antifreeze G12 ++ ndi yapadziko lonse lapansi, ndipo ngati isintha mawonekedwe a kachitidwe kozizirirako, ndiye kuti ndizopanda pake. Nthawi yomweyo, zodzitchinjiriza za kalasi iyi ya zoziziritsa kukhosi ndizokwera, ndipo phukusi lowonjezera lowonjezera lidzateteza dongosolo lililonse kuti lisawonongeke.
2. M'malo mwa G11 antifreeze, mukhoza kudzaza G12 + pazifukwa zomwezo zomwe zafotokozedwa m'ndime yoyamba. Komabe, mu nkhani iyi, pakhoza kukhala kuchepa pang'ono gwero la zinthu munthu wa dongosolo kuzirala injini.
3. Mutha kuwonjezerana wina ndi mnzake pang'onopang'ono, mpaka 10%, mtundu wa antifreeze G11 ndi G12 (kuphatikiza zosintha zawo zonse). Chowonadi ndi chakuti zowonjezera za zoziziritsa kuziziritsazi siziwonongeka ndipo sizimawomba panthawi yolumikizana, koma pokhapokha ngati zakumwazo zimakhala zapamwamba kwambiri ndipo zimapangidwa motsatira miyezo.

Zimaloledwa, koma osavomerezeka, kudzaza kalasi ya G11 yozizira m'malo mwa G12 antifreeze. Kusakhalapo kwa zowonjezera zowonjezera kungachepetse chitetezo cha mphira ndi zigawo zachitsulo ndikuchepetsa moyo wazinthu zadongosolo.

Ndikosatheka kudzaza kalasi yozizirira G12 pamodzi ndi antifreeze G11 yofunikira. Izi zidzasokoneza mphamvu ya kutentha kwa kutentha ndipo zimatha kuyambitsa kuwira kwa injini.
