Jenereta ya nthunzi imagwiritsidwa ntchito pokonza njerwa zapamtunda

1. Nthunzi kuchiritsa malo njerwa

Njerwa zamtundu ndi mtundu wa njerwa zomwe zadziwika kwambiri m'zaka zaposachedwa. Amagwiritsidwa ntchito kwambiri pakuyika minda ya tapala, mabwalo ndi malo ena, ndipo ali ndi zokongoletsera zabwino. Kuphatikiza pa kukongola, njerwa zapamwamba zapamwamba zimatsindika kutentha kwake, madzi absorption, kukana kuvala ndi mphamvu yonyamula mphamvu. Kukonzekera kwa njerwa zamtundu kumakhudza mwachindunji ntchito ya landscmbe bricks. Opanga njerwa ambiri amasankha kugwiritsa ntchito kuchiritsa kwa nthunzi.

2. Kuyanika kwa nthunzi, mphamvu yapamwamba

Njira zowumitsa zomangira njerwa zowoneka bwino zimaphatikiza kuyanika mu uvuni wotentha kwambiri komanso kuyanika nthunzi. Njerwa zapamtunda zikaumitsidwa mu uvuni wotentha kwambiri zimagwiritsidwa ntchito ngati njerwa zapabwalo, sizilimbana ndi chisanu, sizimalola nyengo, zimakhala zosavuta kumera moss pa njerwa, ndipo zimakhala ndi moyo waufupi. ndi

Kugwiritsa ntchito nthunzi kukonza njerwa zowoneka bwino sikufuna kuwombera moto. Mpweya wotentha kwambiri wopangidwa ndi jenereta wa nthunzi umagwiritsidwa ntchito pokonzekera bwino pamalo okwera kwambiri komanso chinyezi, zomwe zimafulumizitsa kuuma kwa njerwa zapamtunda ndipo zimatha kufikira mulingo wamphamvu womwe watchulidwa pakanthawi kochepa.

Njerwa zapamtunda zochiritsidwa ndi nthunzi zimakhala ndi mphamvu zapamwamba komanso kukana bwino, komanso zimakhala ndi ntchito yotetezera kutentha ndi kutsekemera kwa mawu. Pambuyo pa kunyezimira m'nyengo yozizira mvula ndi matalala, kuyamwa madzi, kuzizira ndi kusungunuka, palibe kuwonongeka pamwamba.

Kuchiritsa nthunzi, kuyamwa bwino madzi

Kuphatikiza pa kuuma komwe kumafunikira kuti mukwaniritse mphamvu zomwe zafotokozedwazo pochiritsa njerwa zam'mlengalenga, kuyamwa kwamadzi ndikofunikiranso. Pali ma pores otseguka ndi otsekedwa amitundu yosiyanasiyana ya pore muzinthu za njerwa, ndipo porosity ndi pafupifupi 10% -30%. Porosity ndi kapangidwe ka pore zimakhudza mwachindunji mawonekedwe a malo.

Kutentha kosalekeza ndi kutentha kwa nthunzi komwe kumapangidwa ndi jenereta ya nthunzi kumatha kusinthasintha komanso mosalekeza mkati mwa thupi la njerwa, kulola kuti chinthucho chiwumitse pansi pamikhalidwe yoyenera, kuonetsetsa kuti kunja ndi mkati mwa preform kumatenthedwa mofanana, ndikuwongolera mpweya. permeability wa mankhwala. Ndi njerwa zowonongeka ndi nthunzi, madzi osonkhanitsidwa pamwamba pa njerwa m'masiku amvula amatha kuthamanga mofulumira kulowa mu ngalande.

3. Kuchiritsa nthunzi, kuchita bwino kwambiri komanso kuzungulira kwaufupi

Kukonza njerwa zachikhalidwe kumakonda kukhala ndi zovuta zabwino monga kuwotcha, kuwotcha, ming'alu yambewu youma, ndi zina zambiri, komanso kuchiritsa kwa nthunzi sikumayambitsa zinthu zolakwika.

Zimamveka kuti kugwiritsa ntchito nthunzi kusunga njerwa zamtundu sikungangotsimikizira ubwino, komanso kufupikitsa nthawi yopangira. Kutentha kwa kutentha kwa nthunzi yopangidwa ndi jenereta ya nthunzi ndikokwera kwambiri, ndipo njira yochepetsera nthunzi imatha kutha mkati mwa maola 12 pamalo osindikizidwa, omwe angafupikitse nthawi yopangira zinthu zambiri.
