Momwe mungachepetsere chidwi cha antifreeze?
Kodi antifreeze concentrate ndi chiyani?
Antifreeze yoyikirapo imakhala ndi gawo limodzi lokha lomwe likusowa: madzi osungunuka. Zina zonse (ethylene glycol, zowonjezera ndi colorant) nthawi zambiri zimakhalapo mokwanira.
Zozizira zoziziritsa kukhosi nthawi zambiri zimasokonezedwa molakwika ndi ethylene glycol yoyera. Opanga ena amawonetsa pamapaketi kuti pali ethylene glycol yokha mkati. Komabe, izi sizingakhale zoona chifukwa ethylene glycol ndi madzi opanda mtundu. Ndipo pafupifupi zonse zimatengera mitundu malinga ndi kalasi yovomerezeka (G11 - wobiriwira, G12 - wofiira kapena wachikasu, etc.).
M'mbuyomu, zoziziritsa kuziziritsa zopanda mtundu zinali zogulitsidwa. Iwo mwina ankagwiritsa ntchito pure ethylene glycol. Komabe, ndi osafunika kugwiritsa ntchito maganizo amenewa pokonzekera apamwamba amasankha ozizira. Zowonadi, popanda zowonjezera, dzimbiri zachitsulo ndi kuwonongeka kwa mapaipi a rabara zidzakula kwambiri. Ndipo nyimbozi zinali zoyenera kupititsa patsogolo kutentha kochepa kwa antifreeze yomwe inatsanuliridwa kale.
Tekinoloje yobereketsa ndi kuchuluka kwake
Choyamba, tiyeni tiwone momwe mungasakanizire concentrate ndi madzi kuti musamathire zomwe zatuluka pambuyo pake.
- Kutsatira zomwe muyenera kuthira zilibe kanthu. Komanso chidebe chomwe kusakaniza kudzachitika. Ndikofunikira kusunga magawo.
- Thirani madzi mu thanki yowonjezera poyamba, ndiyeno ganizirani, nthawi zina ndizotheka, koma osafunika. Choyamba, ngati mukukonzekera antifreeze nthawi yomweyo kuti mulowe m'malo mwathunthu, ndiye kuti ndalama zomwe munawerengera sizingakhale zokwanira. Kapena, mosiyana, mumapeza antifreeze yochuluka kwambiri. Mwachitsanzo, munatsanulira malita atatu amadzimadzi, ndiyeno munakonzekera kuwonjezera malita atatu a madzi. Chifukwa iwo ankadziwa kuti voliyumu okwana ozizira mu dongosolo ndi 3 malita. Komabe, 3 malita a concentrate akwanira popanda mavuto, ndipo 6 malita okha amadzi adalowa. Chifukwa kunalibe antifreeze yakale mu dongosolo, kapena pali radiator yopanda muyezo, kapena pali chifukwa china. Ndipo m'nyengo yozizira, pa kutentha pansi -3 ° C, ndizoletsedwa kudzaza zakumwa padera. Zodabwitsa, koma zoona: ethylene glycol yoyera (komanso antifreeze concentrate) imaundana pa -2,5 ° C.
- Osawonjezera mothira kuchokera ku chozizirira chimodzi kupita ku chimzake. Pali zochitika pamene, pakusakaniza koteroko, zina mwazowonjezera zimasemphana ndi kugwa.
Pali mitundu itatu yosakanikirana yodziwika bwino ya zozizira:
- 1 mpaka 1 - antifreeze yokhala ndi malo oziziritsa pafupifupi -35 ° C imapezeka potuluka;
- 40% kuganizira, 60% madzi - mumapeza choziziritsa chomwe sichimazizira mpaka -25 ° C;
- 60% kuganizira, 40% madzi - antifreeze kupirira kutentha mpaka -55 ° C.
Kuti mupange antifreeze ndi malo ena oziziritsa, pali tebulo pansipa lomwe likuwonetsa mitundu ingapo ya zosakaniza zomwe zingatheke.
