Zingwe zosagwirizana ndi kutentha pang'ono (zomwe nthawi zambiri zimatchedwa "zingwe zosagwirizana ndi kuzizira") ndi mtundu wa zingwe zapadera zomwe zimapangidwa kuti zigwiritsidwe ntchito m'malo otentha kwambiri. Chimake chake chimakhala kugwiritsa ntchito zipangizo zapadera zosagwirizana ndi kutentha pang'ono, zomwe zimathandiza kuti zisunge mphamvu zamagetsi ndi makina abwino ngakhale m'malo ovuta kwambiri kuyambira -40°C mpaka -60°C. Mosiyana ndi zimenezi, zingwe zokhazikika zimawonongeka mofulumira m'malo otere ndipo sizingatsimikizire kuti zikugwira ntchito bwino komanso motetezeka.
1. Kusiyana Kofunikira: Kusankha Zinthu
Zipangizo ndiye chinthu chachikulu chomwe chimatsimikizira kukana kwa chingwe kutentha kochepa, makamaka komwe kumaonekera mu insulation ndi sheathing.
Zipangizo Zotetezera Kutentha
Zingwe Zosatentha Kwambiri: Gwiritsani ntchito zipangizo zapadera zotetezera kutentha monga fluoropolymers, Polyurethane (PU), PVC yosinthidwa kutentha kochepa, ndi Cross-Linked Polyethylene (XLPE) yotenthetsera kutentha kochepa. Zipangizozi zili ndi kapangidwe ka mamolekyulu okhala ndi kusinthasintha kochepa kutentha, kuonetsetsa kuti gawo lotetezera kutentha silikusweka kapena kufooka pamene kuli kozizira kwambiri.
Zingwe Zokhazikika: Nthawi zambiri amagwiritsa ntchito PVC yokhazikika kapenaXLPE, yomwe imauma mofulumira komanso kusweka kutentha kochepa, zomwe zimapangitsa kuti kutenthetsa kwa zinthu zotenthetsera kulephereke.
Zipangizo Zophimbira
Zingwe Zosatentha Kwambiri: Chigoba chakunja nthawi zambiri chimagwiritsa ntchito Nitrile Rubber, Chloroprene Rubber (CR), EPDM, Thermoplastic Polyurethane (TPU), kapena zopangidwa mwapadera zotentha pang'ono.Zipangizo za LSZHZipangizozi sizimangopirira kutentha kochepa komanso zimaperekanso kukana kukwawa, kukana mafuta, kukana UV, komanso kukana nyengo, zomwe zimateteza chingwecho mokwanira.
Zingwe Zokhazikika: Chigobacho chimapangidwa makamaka ndi PVC kapena Polyethylene (PE), yomwe imatha kukalamba ndi kusweka chifukwa cha kutentha kochepa komanso malo ovuta, zomwe zimataya ntchito yake yoteteza.
2. Kusiyana kwa Kapangidwe ndi Kagwiridwe ka Ntchito
Kutengera ndi zinthu zomwe zimapangidwira, mitundu iwiri ya zingwe imasonyeza kusiyana kwakukulu pa kapangidwe kake ndi magwiridwe antchito omaliza.
Kapangidwe ka Kondakitala ndi Kapangidwe ka Kapangidwe
Zingwe Zosagwira Kutentha Kwambiri:
Kondakitala: Nthawi zambiri amagwiritsa ntchito waya wa mkuwa wopangidwa ndi zingwe zambiri, wosalala kwambiri, wopangidwa bwino wopanda mpweya kapena wopangidwa ndi zitini, zomwe zimapangitsa kuti chingwecho chikhale cholimba komanso cholimba.
Kapangidwe: Kutalika kwa malo ogona pakati komanso kuwonjezera ulusi wokoka, zigawo zotsutsana ndi kupindika, kapena zigawo zolumikizira kuti ziwonjezere kupindika, kupindika, ndi kukana kugwedezeka, koyenera kugwiritsidwa ntchito posuntha.
Zingwe Zokhazikika: Kapangidwe kake kamapangidwira kuti kakhazikitsidwe mosasunthika kutentha kozungulira, ndi kusinthasintha kochepa kwa kondakitala komanso mphamvu zochepa zamakina.
Kuyerekeza Magwiridwe Abwino Kwambiri
Zingwe Zosagwira Kutentha Kwambiri:
Kugwira Ntchito kwa Makina: Kumakhala ndi kusinthasintha kwakukulu, mphamvu yolimba, komanso kukana kutopa ngakhale kuzizira kwambiri.
Magwiridwe Amagetsi: Amatha kusunga kukana kokhazikika kwa kutenthetsa ndi kupirira milingo yamagetsi, ndi mphamvu yabwino kwambiri yoyendetsera magetsi.
Kulekerera Zachilengedwe: Ili ndi kukana kwabwino kwa kukanda, kukana dzimbiri ndi mankhwala, komanso kukana nyengo.
Zingwe Zokhazikika:
Kugwira Ntchito kwa Makina: Kumataya kusinthasintha kutentha kochepa; chivundikiro ndi chotetezera kutentha zimatha kusweka, zomwe zimapangitsa kuti zikhale zosavuta kuwonongeka ndi makina.
Kugwira Ntchito kwa Magetsi: Kukana kwa kutentha kumachepa kwambiri, chiopsezo cha kuwonongeka chimawonjezeka, zomwe zimapangitsa kuti pakhale zoopsa zazikulu zachitetezo.
3. Zochitika Zogwiritsira Ntchito ndi Zoganizira Zachuma
Kusiyana kwa magwiridwe antchito kumatsimikizira mwachindunji magawo omwe amagwiritsidwa ntchito komanso momwe chuma chikuyendera.
Zochitika Zogwiritsira Ntchito
Zingwe Zosatentha Kwambiri: Ndi chisankho chofunikira m'madera monga madera akumpoto, malo osungiramo zinthu zozizira m'mafakitale, malo okwera kwambiri, malo osungiramo sitima, mphamvu ya mphepo yakunja, zida za m'nyanja yakuya, zitsulo, mankhwala a petrochemical, ndege, ndi kafukufuku wa Antarctic.
Zingwe Zokhazikika: Zimagwiritsidwa ntchito pogawa magetsi m'nyumba, komanso m'nyumba wamba zamafakitale ndi zapakhomo m'malo otentha komanso m'malo ena otentha.
Kukhazikitsa ndi Kusamalira
Zingwe Zosatentha Kwambiri: Zopangidwira kuyika kutentha kochepa; nthawi zina, zingagwiritsidwe ntchito ndi njira zotenthetsera zisanayambike, zomwe zimapangitsa kuti kuyika kukhale kosavuta, kudalirika kwa makina, komanso kusakonza pafupipafupi.
Zingwe Zokhazikika: Kuyika m'malo otentha kwambiri n'koletsedwa kwambiri, chifukwa kungayambitse kuwonongeka kosatha kwa chotenthetsera, zomwe zimapangitsa kuti pakhale ndalama zambiri zokonzera.
Kusanthula Mtengo
Zingwe Zosatentha Kwambiri: Chifukwa chogwiritsa ntchito zipangizo zapadera komanso njira zovuta, mtengo woyambira wogulira ndi wokwera. Komabe, mkati mwa malo omwe adapangidwira, amapereka magwiridwe antchito odalirika komanso moyo wautali wautumiki, zomwe zimapangitsa kuti mtengo wonse wa umwini ukhale wotsika.
Zingwe Zokhazikika: Zingwe zoyambira zimakhala ndi mtengo wotsika, koma ngati zigwiritsidwa ntchito molakwika m'malo otentha pang'ono, zingayambitse kulephera pafupipafupi, nthawi yogwira ntchito, komanso ngozi, zomwe zimapangitsa kuti mtengo wonse ukhale wokwera.
Chidule
Kusankha pakati pa zingwe zoteteza kutentha pang'ono ndi zingwe zokhazikika si chisankho chophweka chongotengera mtengo, koma chisankho chaukadaulo wa makina chomwe chimatsimikiziridwa ndi kutentha kwa malo ogwiritsira ntchito. Kusankha kolondola ndiye chinthu chofunikira kwambiri kuti makina amagetsi azigwira ntchito bwino, mokhazikika, komanso kwa nthawi yayitali m'malo otentha pang'ono.
