Zosefera dziweMchenga umakhala waufupi, ngati muusamalira (kutsuka mchenga wanu pakadutsa milungu 3-5 iliyonse ndikuuyeretsa mozama ka 2-4 pachaka), mchenga wanu wa dziwe uyenera kupitilira 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 zonyansa zomwe zimamangika zimakhalanso ngati kusefera kwamadzi omwe amadutsa musefa.

Koma potsirizira pake, mchenga wamfuti sumasefa bwino, pfuti zonse zimamangika ndipo thanki yosefera imatsekeka.

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