Zosefera dziweUtali wa moyo wa mchenga ndi waufupi, ngati muusamalira (kutsuka msana wanu zosefera pamchenga pakatha milungu 3-5 iliyonse ndikuuyeretsa mozama ka 2-4 pachaka), mchenga wanu wa dziwe uyenera kukugwirani mpaka zaka zisanu.

Kodi izi zikutanthauza kuti kusintha mchenga nthawi zambiri ndi chisankho chabwino?

Yankho lokhwima ndi ayi.Pali malo okoma oti mchenga wanu ukhale wazaka zingati.Mchenga wa dziwe umakhala wothandiza kwambiri pakatha zaka ziwiri zogwiritsidwa ntchito chifukwa kwa zaka zingapo zoyamba zoipitsa zomwe zimamangika zimakhalanso ngati kusefera kwamadzi omwe amadutsa muzosefera.

Koma pamapeto pake, mchenga wamfuti sumasefa bwino, mfuti zonse zimachulukana ndipo thanki yosefera imatsekeka.

Nazi zizindikiro zina zomwe muyenera kusintha mchengazo ndi izi: kuthamanga kwa magazi (kuthamanga kukafika pamwamba pa 10 psi), kusuntha (tsegulani fyuluta ya padziwe ndikuyang'ana mikwingwirima mumchenga kapena mipata yomwe madzi amatha kudutsa mosavuta), ndi madzi amitambo.
