Chinovhara mvura yekuchera
Mushonga wedu wekuputira mvura yekuboora imhinduro yemazuva ano inovandudza mashandiro ekuboora uye inovandudza kugona kwekugadzira. Nekugadzikana kwakanyanya kwekupisa, kushandira pamwe nemaitiro akasiyana-siyana emvura yekuboora, uye kudzora kurasikirwa nemvura zvinobudirira, inochinja-chinja indasitiri yemafuta negasi. Uyezve, kuora kwayo kunoratidza kuzvipira kwedu kukuchengetedza nharaunda. Nekubatanidza mushonga wedu wekuputira mumabasa ako ekuboora, unogona kusimudzira mashandiro emvura yekuboora uye kuwana kugona kwakanyanya kwekuboora.

Kurongedza nekutakura
Shandisa bhegi repurasitiki rakarukwa rine mapuranga maviri nemashanu kana mapepa epurasitiki akabatanidzwa. Rinogonawo kurongwa zvichienderana nezvinodiwa nemushandisi. Panguva yekuchengetera nekutakura, teerera kudzivirira kupisa nehunyoro, jira rekurongedza harifanirwe kudarika jira makumi maviri. Nguva yekuchengetedza inoshanda makore maviri.
Nyaya dzinoda kutariswa:
Dzivisa kusangana nemaziso, ganda nembatya, kana kusuka nemvura yakawanda. Chengeta kure nemoto.
1. Ndeapi marudzi emakemikari anoshandiswa zvakanyanya munzvimbo dzemafuta aripo?
Makemikoro akasiyana-siyana emumunda wemafuta anowanikwa kugadzirisa matambudziko chaiwo muindasitiri yemafuta negasi. Makemikoro anoshandiswa kazhinji anosanganisira mabhakitiriya, zvinodzivisa ngura, zvinobvisa munyu, zvinodzivisa kukweshana, zvinoderedza kukweshana, zvinogadzirisa manyuko emafuta, zvinogadzirisa mafuta uye zvinogadzirisa acid, nezvimwewo.
2. Ungatenga sei makemikari emumunda wemafuta?
Makemikoro emumunda wemafuta anogona kutengwa kuburikidza nevanotengesa makemikari vane marezenisi avo vanonyanya kugadzira zvigadzirwa zvakagadzirirwa kushandiswa kwemafuta negasi. Vatengesi ava vanowanzova nemapoka enyanzvi akazvipira anogona kupa mazano pakusarudza nekushandisa makemikari akakodzera zvichienderana nezvinodiwa chaizvo.
