Mchenga woponya ndi mtundu woponyera. Maumbedzi omwe amagwiritsidwa ntchito mumchenga akuponya michere nthawi zambiri imakhala ndi nkhungu yakunja komanso pakati. Chifukwa zida zoumba zomwe zimagwiritsidwa ntchito mumchenga ukuponya ngati wotsika mtengo ndipo mosavuta, ndipo kupanga nkhungu ndikosavuta, kumatha kuzolowera kupanga chimodzi, kupanga ma cratch ndi kupanga kwakukulu kwamitengo. Kwa nthawi yayitali, zakhala zikuchitika moyenera pakupanga. Pakadali pano, padziko lonse lapansi, pakupanga katatu, 60 mpaka 70% ya zingwe zimapangidwa ndi mchenga wamchenga, ndipo pafupifupi 70% ya iwo amapangidwa ndi nkhungu yamchenga ya dongo.
Kufotokozera kwa zinthu
Mchenga woponyera umatanthawuza njira yopangira zotulutsa mumchenga. Zitsulo, chitsulo, komanso zinyalala zambiri zopanda mphamvu zitha kupezeka pogwiritsa ntchito njira yobwereka mchenga. Chifukwa cha zida zotsika mtengo komanso zopezeka mosavuta zomwe zimagwiritsidwa ntchito mumchenga woponya, komanso mosavuta pakupanga nkhungu, kwakhala nthawi yayitali pakupanga kopanga, koyenera kwa chidebe chimodzi, komanso kupanga kwakukulu.
Mchenga woponya madera omwe akutulutsa akuluakulu, monga mbale zamphongo, mbale zapamwamba kwambiri, makhoma, ndikupera makhoma. M'matonthoza ophwanya, magawo awa amavala ndi akulu osadziwika. Mwachitsanzo, mbale za jindazi zimatulutsa pafupifupi osafuna kuti malumbidwe owoloka, ndikupukuta makoma ophwanya, ndipo zikopa zopangira zimafunikira kuwononga. Chifukwa chake, kuponya kwa mchenga ndikoyenera makamaka kwa magawo awa chifukwa malo ovala mitengo yamphesa yotakata, makhoma a chromium, akupera makhoma oposa 20% poyerekeza ndi ma ax otayika. Komabe, kutaya kwa sera komwe kumapereka kulondola kwapamwamba, zovomerezeka zazing'ono, kusinthasintha kwa mchenga wowuma, ndikuchepetsa ntchito yoyeretsa ndi kupukuta ndalama zoposa 50%, ndikuyika mtengo wamawu otayika.
Magawo a mchenga obwera ndi kampani yathu yopangidwa makamaka: Kuvala mitu yolimba, kutuluka kwamphamvu, matenthedwe otenthetsa, matope osapanga dzimbiri, olandirira kugula.
