Nsanja iliyonse yozizira imakhala yoyeretsa mpweya wambiri womwe umatha kuchotsa mpweya wodetsa mpweya. Kuphatikiza pa tizilombo tating'onoting'ono, timu, ndi matupi ena achilendo, madzi ofatsa koma ofatsa koma kwambiri amawathandiza kwambiri kuwononga zachilengedwe. Pa dongosolo lotseguka ili, chifukwa cha kuchuluka kwa mankhwala, mankhwalawa amasungidwa nthawi zonse, chifukwa chotayika kwambiri. Nthawi zambiri, kufupikira kwamadzi ndikosakwanira, kuloleza tinthu tating'ono tomwe timalowa mu kachitidwe kukakhala kumeneko kwamuyaya. Kuphatikiza apo, kuchuluka kwakukulu kwa oxide ndi tinthu tina tinthu tomwe timasonkhana pamodzi, ndikupanga zovuta zambiri zazomwe zimawononga m'magazi otsekemera kwambiri.
2. Kutentha kawiri
Kubwerera m'ma 1950s, nyumba zina zapadera, ma kondominium, ndi nyumba zina zozizira komanso kapangidwe kake, komanso makina opukusira awa tsopano akutha kutha kwa moyo wawo wothandiza kudutsa dzikolo.
Kutentha komanso kosavuta komanso kosavuta kumagwiritsidwa ntchito popereka madzi otentha kapena ozizira kupita pazenera lotenthetsedwa ndi mitanda yocheperako komanso yaying'ono. Zinthu zina zopindika nthawi zambiri zimakhala zowonda kwambiri ngati 1-inchi fiberglass, koma ndizosatheka kuti zizigwiritsa ntchito chinyezi ndipo nthawi zonse zimakhala zovuta kuyika malo oyenera. Chitoliro chachitsulo chokha sichinapangidwenso opazidwa, chosasunthika kapena chokana-cordomiion kapena madziwo amatha kulowa mu chipilala ndikutchinga chitoliro kuchokera kunja.
3. Moto wowaza chitoliro
Kwa machitidwe onse oteteza moto, mawu oyamba ndi madzi abwino ndiye chifukwa chachikulu chowonongeka. Mapipi akale achikale amayamba kuchitika mpaka m'ma 1920s ndipo m'mbuyomu sanathe kutsutsidwa kapena cholinga china chilichonse, koma kuyezetsa akupanga nthawi zambiri kumapeza mapaipi awa pafupi. Mu njira zonse zotetezera moto, malo ofunikira kwambiri ophukira amakhala kumayambiriro kwa dongosolo la dongosolo lamadzi. Apa, chilengedwe cham'madzi chatsopano chimapanga zotayika zapamwamba kwambiri (nthawi zambiri zimasiyana kwambiri ndi dongosolo lopumira).

Pafupifupi machitidwe onse a Phiping, gulu lankhondo lachitsulo lomwe linakhomeredwa mwachindunji kwa ma valves a mkuwa kubweretsa zolephera zina. Makamaka chitsulo cholunjika pakati pa mavalidwe awiri a mkuwa, zotsatirapo zowonongeka zidzatsitsidwanso.
Pamene chitoliro cha galvanazen chikugwirizana ndi chitsulo cha mkuwa kapena mkuwa, padzakhala zizolowezi zamphamvu pakati pa zitsulo zosiyanasiyana ndikuwononga pansi pa zinc. M'malo mwake, zazing'ono zomwe zimayenda pakati pa zitsulo ziwiri ndizofanana ndi batri yokhazikitsidwa ndi zinc. Chifukwa chake, kugwada kumakhala kovuta kwambiri m'dera lomwe limalumikizidwako, nthawi zambiri kumakhudza ulusi wofowoka kale kuti ubweretse kutulutsa kapena zolephera zina.
