Thirani kapena okonzeka kupanga antifreeze. Chabwino nchiyani?
Zamkatimu
Kodi antifreeze concentrate imakhala ndi chiyani ndipo imasiyana bwanji ndi zomwe zamalizidwa?
Antifreeze yomwe yakonzeka kugwiritsidwa ntchito imakhala ndi zigawo zinayi zazikulu:
- ethylene glycol;
- madzi osungunuka;
- phukusi zowonjezera;
- utoto.
The maganizo akusowa chimodzi chokha cha zigawo zikuluzikulu: madzi osungunuka. Zotsalira zomwe zili muzolemba zonse zili mumitundu yokhazikika ya zoziziritsa kukhosi. Nthawi zina opanga, kuti athetse ndikupewa mafunso osafunika, amangolemba "Glycol" kapena "Ethandiol" pamapaketi, omwe, kwenikweni, ndi dzina lina la ethylene glycol. Zowonjezera ndi utoto nthawi zambiri sizimatchulidwa.
Komabe, nthawi zambiri, zigawo zonse zowonjezera ndi utoto zilipo m'mapangidwe onse opangidwa ndi odzilemekeza okha. Ndipo madzi akawonjezedwa mugawo loyenera, zotulutsa zake zimakhala antifreeze wamba. Masiku ano pamsika pali makamaka antifreezes G11 ndi G12 (ndi zotumphukira zake, G12 + ndi G12 ++). G13 antifreeze amagulitsidwa atakonzeka kale.
Mugawo lotsika mtengo, mutha kupezanso ethylene glycol wamba, osapindula ndi zowonjezera. Ayenera kugwiritsidwa ntchito mosamala, chifukwa mowa womwewo umakhala ndi nkhanza pang'ono. Ndipo kusowa kwa zowonjezera zoteteza sikungalepheretse kupanga malo owononga kapena kuyimitsa kufalikira kwake. Zomwe m'kupita kwa nthawi zidzachepetsa moyo wa radiator ndi mapaipi, komanso kuwonjezera kuchuluka kwa ma oxide opangidwa.
Kodi antifreeze kapena antifreeze concentrate ndi chiyani?
Pamwambapa, tapeza kuti pankhani ya mankhwala pambuyo pokonzekera kwambiri, sipadzakhala kusiyana kulikonse ndi zomwe zamalizidwa. Izi zili ndi chikhalidwe kuti magawowo aziwonedwa.
Tsopano ganizirani ubwino wa kuika maganizo pa zomwe zamalizidwa.
- Kuthekera kokonzekera antifreeze ndi malo oziziritsa omwe ali oyenerana ndi momwe zinthu ziliri. Ma antifreeze okhazikika amavotera -25, -40 kapena -60 °C. Ngati mumadzikonzekeretsa nokha choziziritsa kukhosi, ndiye kuti mutha kusankha kukhazikika kwadera lomwe galimotoyo imayendetsedwa. Ndipo pali mfundo imodzi yobisika apa: kutsika kwa kutentha kwa ethylene glycol antifreezes, kumachepetsa kukana kuwira. Mwachitsanzo, ngati antifreeze ndi kuthira mfundo ya -60 ° C kuthiridwa kuchigawo chakumwera, ndiye kuti chithupsa chikatenthedwa kwanuko mpaka + 120 ° C. Mpata wotere wa ma motors "otentha" omwe ali ndi kuyendetsa kwambiri amatheka mosavuta. Ndipo posewera ndi gawoli, mutha kusankha mulingo woyenera wa ethylene glycol ndi madzi. Ndipo choziziritsa chotsatira sichidzazizira m'nyengo yozizira ndipo sichidzagonjetsedwa ndi kutentha kwakukulu m'chilimwe.
- Zolondola zokhudza kutentha kwa antifreeze concentrate kudzaundana pa kutentha kotani.
- Kuthekera kowonjezera madzi osungunuka kapena kuyika ku dongosolo kuti musunthire malo othira.
- Zochepa zogula zabodza. Nthawi zambiri amapangidwa ndi makampani otchuka. Ndipo kuwunika kwachiphamaso kwa msika kukuwonetsa kuti pali zabodza zambiri pakati pa antifreeze opangidwa kale.
Zina mwazovuta zodzikonzekeretsa antifreeze kuchokera ku concentrate, munthu angazindikire kufunika kofufuza madzi osungunuka (ndikofunikira kwambiri kuti musagwiritse ntchito madzi apampopi wamba) ndi nthawi yokonzekera mankhwala omalizidwa.
Kutengera zomwe tafotokozazi, ndizosatheka kunena mosakayikira chomwe chili bwino, antifreeze kapena kukhazikika kwake. Kapangidwe kalikonse kali ndi ubwino wake ndi kuipa kwake. Ndipo posankha, muyenera kupitilira zomwe mumakonda.
