Antifreeze cia yuav tsum

Antifreeze feem ntau yog siv rau kev kho tshuab hauv kev faib khoom, thiab koom nrog kev lag luam tshuaj pleev xim raws li nws cov khoom xyaw, yog li thov ua tib zoo saib xyuas cov kev ceev faj hauv qab no.
Khaws rau hauv qhov chaw qhuav thiab txias, thiab tsis txhob nthuav tawm rau lub hnub.
Lub freezing point ntawm antifreeze (muaj ethylene glycol) hloov nrog lub concentration ntawm ethylene glycol nyob rau hauv lub aqueous tov. Thaum cov concentration qis dua 59%, qhov concentration ntawm ethylene glycol nyob rau hauv cov kua aqueous nce thiab qhov khov ntawm qhov qis qis. Txawm li cas los xij, thaum cov concentration ntau dua 59%, raws li qhov concentration ntawm ethylene glycol nce, nws qhov khov khov yuav nce. Thaum cov concentration nce mus rau 100%, nws qhov dej khov nce mus rau -13 degrees. Qhov no yog vim li cas concentrated antifreeze tsis tuaj yeem siv ncaj qha.
