G12 antifreeze ndi chiyani - kusiyana ndi G11, G12 +, G13 ndi yomwe ikuyenera kudzazidwa

Antifreeze ndiyofunikira kuziziritsa injini yagalimoto. Masiku ano, zoziziritsa kukhosi zimagawidwa m'mitundu 4, iliyonse yomwe imasiyana ndi zowonjezera ndi zina. Ma antifreeze onse omwe mumawawona pamashelefu a sitolo amapangidwa ndi madzi ndi ethylene glycol, ndipo ndipamene kufanana kumathera. Ndiye kodi zoziziritsa kukhosi zimasiyana bwanji wina ndi mzake, kuwonjezera pa mtundu ndi mtengo, sankhani antifreeze yoyenera yagalimoto yanu, ndizotheka kusakaniza zoziziritsa kukhosi zosiyanasiyana ndikuzisungunula ndi madzi - werenganibe.

Kodi zoletsa kuwuma ndi chiyani?

Antifreeze ndi dzina lodziwika bwino la zoziziritsa zagalimoto. Mosasamala kanthu za gulu, propylene glycol kapena ethylene glycol alipo mu kapangidwe ka antifreeze, ndi phukusi lake la zowonjezera. 

Ethylene glycol ndi mowa wapoizoni wa dihydric. Mu mawonekedwe ake oyera, ndi madzi amadzimadzi, amakoma, kutentha kwake kumakhala pafupifupi madigiri 200, ndipo kuzizira kwake ndi -12,5 ° Kumbukirani kuti ethylene glycol ndi poizoni woopsa, ndipo mlingo wakupha kwa munthu ndi 300. magalamu. Mwa njira, chiphecho chimachotsedwa ndi mowa wa ethyl.

Propylene glycol ndi mawu atsopano m'dziko lazozizira. Ma antifreezes oterowo amagwiritsidwa ntchito m'magalimoto onse amakono, okhala ndi miyezo yolimba ya kawopsedwe, kuwonjezera apo, antifreeze yochokera ku propylene glycol imakhala ndi mafuta abwino kwambiri komanso odana ndi dzimbiri. Mowa woterewu umapangidwa pogwiritsa ntchito gawo lopepuka la distillation yamafuta.

Kumene komanso momwe ma antifreezes amagwiritsidwira ntchito

Antifreeze anapeza ntchito yake m'munda wa zoyendera msewu. Nthawi zambiri amagwiritsidwa ntchito mu Kutentha kwa nyumba zogona ndi malo. Kwa ife, ntchito yaikulu ya antifreeze ndi kusunga kutentha kwa injini mumayendedwe operekedwa. Coolant imagwiritsidwa ntchito mu jekete yotsekedwa ya injini ndi mzere, imadutsanso m'chipinda chokwera, chifukwa chomwe mpweya wotentha umawomba pamene chitofu chayatsidwa. Pa magalimoto ena pali chotenthetsera kutentha kwa kufala kokha, kumene antifreeze ndi mafuta zimadutsana mu nyumba imodzi, kuwongolera kutentha kwa wina ndi mzake.

M'mbuyomu, chozizira chomwe chimatchedwa "Tosol" chimagwiritsidwa ntchito mgalimoto, pomwe zofunika kwambiri ndi izi:

• kukhalabe kutentha;
• mafuta mafuta.

Uwu ndi umodzi mwamadzi otsika mtengo kwambiri omwe sangathe kugwiritsidwa ntchito mgalimoto zamakono. Ma antifreezes angapo apangidwa kale kwa iwo: G11, G12, G12 + (++) ndi G13.

Woletsa mphepo G11

Antifreeze G11 imapangidwa pamakina osakanikirana a silicate, ili ndi phukusi la zowonjezera zowonjezera. Chozizira ichi chidagwiritsidwa ntchito pamagalimoto omwe adapangidwa chaka cha 1996 chisanafike (ngakhale kulolerana kwa magalimoto amakono mpaka 2016 kumapangitsa kudzaza G11), ku CIS amatchedwa "Tosol". 

Chifukwa cha maziko ake osalala, G11 imagwira ntchito zotsatirazi:

• Amateteza malo, kuteteza ethylene glycol kuti asawawononge;
• imachedwetsa kufalikira kwa dzimbiri.

Mukamasankha antifreeze (mtundu wake ndi wabuluu ndi wobiriwira), mverani zinthu ziwiri:

• alumali moyo satha zaka 3, mosasamala kanthu za mileage. Pogwira ntchito, zotchingira zimakhala zocheperako, zidutswa izi, zikafika poti zimaziziritsa, zimapangitsa kuti ziziyenda bwino, komanso kuwononga mpope wamadzi;
• zotchingira sizimalekerera kutentha kwakukulu, kuposa madigiri a 105, kotero kutentha kwa G11 ndikotsika.

Zoyipa zonse zimatha kudutsika posintha zoletsa kuwuma ndikuletsa kutenthetsa injini. 

Kumbukiraninso kuti G11 siyoyenera magalimoto omwe ali ndi zotchinga za aluminiyamu ndi radiator chifukwa choziziritsa sichingathe kuwateteza pakatentha kwambiri. Samalani posankha opanga otsika mtengo, monga Euroline kapena Polarnik, funsani mayeso a hydrometer, nthawi zambiri zimachitika pomwe woziziritsa wotchedwa "-40 °" amatembenukira kukhala -20 ° kapena kupitilira apo.

 Antifreeze G12, G12 + ndi G12 ++

Mtundu wa G12 antifreeze ndi wofiira kapena pinki. Ilibenso ma silicates pamapangidwe ake, amachokera ku mankhwala a carboxylate ndi ethylene glycol. Wapakati moyo utumiki wa ozizira chotero ndi zaka 4-5. Chifukwa cha zowonjezera zosankhidwa bwino, anti-corrosion properties amagwira ntchito mosankha - filimuyo imapangidwa kokha m'malo owonongeka ndi dzimbiri. G12 antifreeze imagwiritsidwa ntchito mu injini zothamanga kwambiri ndi kutentha kwa madigiri 90-110.

G12 ili ndi vuto limodzi lokha: zotsutsana ndi dzimbiri zimangowoneka dzimbiri lili pomwepo.

Nthawi zambiri G12 imagulitsidwa ngati kusakanikirana ndi "-78 °" kapena "-80 °", chifukwa chake muyenera kuwerengera kuchuluka kwa zoziziritsa m'dongosolo ndikuisungunula ndi madzi osungunuka. Kuchuluka kwa madzi ndi zoletsa kuwuma kudzawonetsedwa pamalowo.

Za G12 + zoletsa kuwuma: sizosiyana kwambiri ndi zomwe zidakonzedweratu, mtunduwo ndi wofiira, wowongolerayo wakhala wotetezeka komanso wowononga zachilengedwe. Zikuchokera lili zina odana ndi dzimbiri, ntchito pointwise.

G12 ++: Nthawi zambiri zofiirira, mtundu wabwino wa zotsekemera zama carboxylated. Ma antifreeze a Lobride amasiyana ndi G12 ndi G12 + pomwe pali zowonjezera zowonjezera, chifukwa chake zida zotsutsana ndi dzimbiri zimagwira ntchito moyenera ndikuletsa kupanga dzimbiri.

Woletsa mphepo G13

Gulu latsopanoli limawombedwa kofiirira. Zophatikiza zosakanizika zimakhala ndi mawonekedwe ofanana, koma mulingo woyenera kwambiri wa silicate ndi zinthu zina zamagulu. Imakhalanso ndi zinthu zabwino zoteteza. Tikulimbikitsidwa kuti musinthe zaka zisanu zilizonse.

Antifreeze G11, G12 ndi G13 - pali kusiyana kotani?

Funso limadza nthawi zambiri - kodi ndizotheka kusakaniza ma antifreeze osiyanasiyana? Kuti muchite izi, muyenera kuyang'ana mu mawonekedwe a chozizira chilichonse kuti mumvetsetse kuyenderana.

Kusiyana kwakukulu pakati pa G11 ndi G12 si mtundu, koma kapangidwe kake: choyambiriracho chili ndi maziko a inorganic/ethylene glycol. Mutha kusakaniza ndi antifreeze iliyonse, chinthu chachikulu ndikuti pali kuyanjana kwamagulu - G11.

Kusiyanitsa pakati pa G12 ndi G13 ndikuti chachiwiri chimakhala ndi propylene glycol base, ndipo gulu lachitetezo cha chilengedwe limakwera kangapo.

Posakaniza zoziziritsa kukhosi:

• G11 siyisakanikirana ndi G12, mutha kungowonjezera G12 + ndi G13;
• G12 imasokoneza G12 +.

Mafunso ndi Mayankho:

Kodi antifreeze imagwiritsidwa ntchito bwanji? Ndi madzimadzi ogwira ntchito a makina oziziritsira injini yagalimoto. Ili ndi malo otentha kwambiri ndipo imakhala ndi madzi ndi zowonjezera zomwe zimapaka pampu ndi zinthu zina za CO.

Chifukwa chiyani antifreeze amatchedwa choncho? Anti (motsutsa) Kuzizira (kuundana). Ili ndi dzina lamadzi onse oletsa kuzizira omwe amagwiritsidwa ntchito m'magalimoto. Mosiyana ndi antifreeze, antifreeze imakhala ndi kutentha kochepa kwa crystallization.

Ndi antifreezes ati omwe alipo? Ethylene glycol, carboxylate ethylene glycol, hybrid ethylene glycol, lobrid ethylene glycol, propylene glycol. Amasiyananso ndi mtundu: wofiira, buluu, wobiriwira.
