ukupholisa okungavuthiwe

I-anti-freeze, eyaziwa ngesenzo esiyinhloko njenge "engine coolant", ihamba emkhakheni wokupholisa wejini. Izinzuzo ezinkulu zokusebenzisa i-anti-freeze zimi kanje:

Ingxenye ye-ethylene glycol ku-antifreeze inganciphisa kakhulu iphuzu lokuqala lokuqanduka kwamanzi, ivumele ukuba ihlale iyiliquid futhi ihambe kahle ezindaweni eziphansi zokushisa ezingu-10 degrees ngaphansi kwenani, ngaleyo ndlela ivikele injini futhi iqinisekise ukuqala okujwayelekile nokusetshenziswa kwemoto ezindaweni ezibandayo, kugwenywe imiphumela emibi yokuqanduka nokuphuka kwenjini.

Iphuzu lokuphehla le-antifreeze lingafinyelela ku-107 ° C-120 ° C. Ngaphandle kwe-antifreeze, amanzi azophola (aphole) ku-100 ° C, akhiqize inani elikhulu lempahla yamanzi futhi abangele ukwanda okukhulu kwengcindezi, okungalimaza uhlelo lokupholisa futhi ngisho ne-engine.

3. I-Antifreeze iqukethe izithasiselo ezahlukene ezisebenza kahle zokulwa nokugqwala, ezingakha ifilimu yokuvikela phezu kobuso bemetal, zihlukanise umswakama nomoya, zivimbele ngempumelelo ukugqwala, ukushisa nokwakheka kwe-scale, futhi zandise impilo yesevisi yesistimu yokupholisa yonke.

4. I-antifreeze isekelwe emanzini akhishiwe i-ion futhi iqukethe izithiyo zokwakheka, ezingavimbela kahle ukwakheka kwe-scale. Vimbela ukuvinjwa ezindleleni zamanzi nasemathangeni amanzi ukuze uqinisekise ukusebenza okuhle nokuzinzile kwesistimu yokupholisa isikhathi eside.

5. I-antifreeze inethonya lokuthambisa emshinini wamanzi, okuyinhloko ye-cycle yokupholisa. I-antifreeze ingathambisa isikhwama sayo sokuvikela futhi wandise impilo yokusebenza yomshini wamanzi.
