Ndi zinthu ziti zotchinjiriza zomwe zili bwino pamapaipi a nthunzi?

Chiyambi cha chisanu chadutsa, ndipo kutentha kwatsika pang'onopang'ono, makamaka kumpoto. Kutentha kumakhala kochepa m'nyengo yozizira, ndipo momwe mungasungire kutentha nthawi zonse pamayendedwe a nthunzi wakhala vuto kwa aliyense. Lero, Nobeth alankhula nanu za kusankha kwa zida zotchinjiriza mapaipi a nthunzi.

Ngakhale pali zida zambiri zotsekera, zida zosiyanasiyana zimakhala ndi magwiridwe antchito osiyanasiyana. Zida zotchinjiriza zomwe zimagwiritsidwa ntchito m'mapaipi a nthunzi ndizopadera kwambiri, koma ndi zida zotani zomwe zimagwiritsidwa ntchito popanga mapaipi a nthunzi? Panthawi imodzimodziyo Muyeneranso kudziwa kuti zipangizo zotetezera mapaipi a nthunzi ndi chiyani, kuti muthe kusankha bwino zinthu zamtengo wapatali.

Ndi zinthu ziti zotsekereza zomwe zimagwiritsidwa ntchito popanga mapaipi a nthunzi?

1. Malinga ndi Article 7.9.3 ya GB50019-2003 "Design Code for Heating, Ventilation and Air Conditioning", posankha zipangizo zotetezera zipangizo ndi mapaipi, chofunika kwambiri chiyenera kuperekedwa ku zipangizo zomwe zimakhala ndi matenthedwe ang'onoang'ono, chinthu chachikulu chokana chinyezi, kuyamwa kwamadzi otsika, kachulukidwe kakang'ono, komanso chuma chambiri. Zida zapamwamba; zipangizo zotchinjiriza ziyenera kukhala zosapsa kapena zosagwira moto; makulidwe a chitoliro chosungunula chitoliro chiyenera kuwerengedwa ndikutsimikiziridwa molingana ndi makulidwe a zachuma mu GB8175 "Malangizo a Mapangidwe a Zida ndi Kusungunula Mapaipi" panthawi yotentha.

2. Zomwe zimagwiritsidwa ntchito nthawi zambiri zimakhala ndi cork, aluminium silicate, polystyrene ndi polyurethane. Zomwe mungagwiritse ntchito ziyenera kuganiziridwa potengera zovuta za payipi ya dongosolo komanso mtengo wazinthu zotchinjiriza. Kawirikawiri, zipangizo zotetezera zomwe zimagwiritsidwa ntchito mu dongosolo ziyenera kukhala zofanana.

3. Masiku ano, kusungunula kwamafuta ambiri kumagwiritsa ntchito zipangizo zolimba zotentha monga cork kapena polystyrene zomwe zakonzedwa kale. Chifukwa kugwiritsa ntchito zida zopangira mafuta opangira matenthedwe ndikosavuta pomanga komanso kutulutsa kwamafuta ndikwabwino kuposa komwe kumakonzedwa pamalowo, chifukwa chake amagwiritsidwa ntchito kwambiri. Komabe, pamtundu woterewu wosokonekera wosanjikiza, ngati chotchinga cha nthunzi sichinasamalidwe bwino, mpweya wamadzi mumlengalenga udzalowa mumipata yotsekera, potero kuwononga magwiridwe antchito.

Kodi zotchingira mapaipi a nthunzi ndi ziti?

1. Chitoliro cha ubweya wa mwala,
Mapaipi a ubweya wa miyala amagwiritsidwa ntchito kwambiri pakutchinjiriza kwa ma boilers kapena mapaipi a zida m'mafakitale monga petrochemical, metallurgy, shipbuilding, and textile industry. Nthawi zina amagwiritsidwa ntchito kwambiri m'makoma ogawa m'mafakitale omanga, komanso padenga lamkati ndi kutsekereza khoma ndi mitundu ina yamafuta otenthetsera. Khalani otentha. Komabe, m'makampani amagetsi, mafakitale a petrochemical, mafakitale opepuka, ndi zina zambiri, njira zotchinjiriza ndi zotenthetsera zamapaipi zimagwiritsidwa ntchito pamapaipi osiyanasiyana, makamaka mapaipi okhala ndi mipata yaying'ono. Mipope ya ubweya wa miyala yosalowa madzi imatha kukhazikitsidwa mwachangu. Lili ndi zinthu zapadera monga kukana chinyezi, kuthamangitsa madzi ndi kutaya kutentha. Ndizoyenera kugwiritsidwa ntchito m'malo amvula. Lili ndi choletsa madzi.

2. Ubweya wagalasi,
Ubweya wagalasi umakhala ndi mawonekedwe abwino, kachulukidwe kakang'ono, komanso kutsika kwamafuta. Ubweya wagalasi ulinso ndi mphamvu yolimbana ndi dzimbiri ndipo umakhala ndi mankhwala abwino m'malo ochita dzimbiri. Makhalidwe osinthika a ubweya wagalasi ndi kutsekemera kwa ma air conditioners, mapaipi otulutsa mpweya, ma boilers ndi mapaipi a nthunzi.

3. Urethane, polyurethane, yomwe imagwiritsidwa ntchito kwambiri popanga kusungirako kuzizira, magalimoto osungiramo firiji kapena mabokosi osungira mwatsopano. Itha kugwiritsidwanso ntchito ngati chosanjikiza cha kutentha kwa mapanelo amitundu zitsulo masangweji. Polyurethane nthawi zina amagwiritsidwa ntchito mu akasinja a petrochemical. Polyurethane imakhalanso ndi ntchito ya kutchinjiriza kwamafuta ndi kuzizira kozizira, ndipo imagwiritsidwa ntchito m'minda ya petrochemical ndi metallurgical. Iwo makamaka chimagwiritsidwa ntchito kunja wosanjikiza chitetezo zosiyanasiyana mobisa gulu mwachindunji anakwiriridwa mapaipi.
