Njengesixhobo sentsimbi esibalulekileyo nesibalulekileyo ekwakheni uqoqosho lwesizwe, imibhobho yentsimbi engenamthungo isetyenziswa kakhulu kwiindawo ezifana nokwakha, ukucubungula oomatshini, kunye nobunjineli bemibhobho (ukuthutha ulwelo nezinto eziqinileyo ezifana namanzi, ioyile, igesi, amalahle, kunye nomphunga webhoyila). Ngenxa yeemeko ezahlukeneyo zokusetyenziswa kunye nokusetyenziswa, kusafuneka ukhethe izixhobo kunye nemigangatho efanelekileyo xa ukhetha ukuthintela inkunkuma kunye nezinto ezingakhuselekanga.
Umbhobho wentsimbi engenamthungo we-20# GB8163 wothutho oluhamba ngolwelo
Ithetha ukuthini impahla yombhobho wentsimbi engenamthungo? Le nto siyibiza rhoqo ngokuba yi-grade, efana ne-20#, 45#, emele ukwakheka kwayo kweekhemikhali kunye neempawu zoomatshini ezifana namandla okutsalwa, amandla okuvelisa, kunye nesantya sokwandiswa. Oku kulandelayo zizixhobo zombhobho wentsimbi engenamthungo ezisetyenziswa rhoqo, imigangatho yemveliso kunye nokusetyenziswa okushwankathelwe ngumbhali.
