Kodi pali kusiyana kotani pakati pa milu ya chitsulo yotentha ndi milu ya chitsulo yozizira?

Mu gawo la uinjiniya ndi zomangamanga,Milu ya Mapepala a Chitsulo(nthawi zambiri amatchedwakuyika mapepala() kwa nthawi yayitali akhala maziko a mapulojekiti omwe amafuna kusungidwa bwino kwa nthaka, kukana madzi, ndi chithandizo cha kapangidwe kake—kuyambira kulimbitsa mtsinje ndi kuteteza gombe mpaka kufukula pansi pa nthaka ndi zotchinga zakanthawi zomangira. Komabe, si Milu yonse ya Zitsulo yomwe imapangidwa mofanana: njira ziwiri zazikulu zopangira—kugubuduza ndi kupanga kozizira—zimapanga zinthu zosiyanasiyana, Milu ya Zitsulo Yotentha Yogubuduzidwa ndi Milu ya Zitsulo Yozizira Yogubuduzidwa, iliyonse ili ndi makhalidwe apadera omwe amawapangitsa kukhala oyenera ntchito zinazake. Kumvetsetsa kusiyana kwawo ndikofunikira kwa mainjiniya, makontrakitala, ndi oyang'anira mapulojekiti kuti apange zisankho zotsika mtengo komanso zoyendetsedwa ndi magwiridwe antchito.

Mitundu iwiri ya njira zopangira mulu wa chitsulo

Njira zopangira mitundu iwiri ya mapepala zimakhazikitsa maziko a makhalidwe awo osiyanasiyana.Mapepala Opangidwa ndi Chitsulo ChotenthaAmapangidwa potenthetsa zitsulo mpaka kutentha kwambiri (nthawi zambiri kupitirira 1,000°C) mpaka chitsulocho chitayamba kufewa, kenako nkuzidutsa m'ma rollers angapo kuti chikhale mawonekedwe olumikizana (monga U-type, Z-type, kapena straight web) omwe amafotokoza momwe mapepala amagwirira ntchito. Njira yotentha kwambiriyi imalola magawo ovuta komanso olimba komanso kuonetsetsa kuti zinthuzo zimakhala zofanana, chifukwa kutentha kumachotsa kupsinjika kwamkati mwa chitsulocho. Mosiyana ndi zimenezi,Mapepala Opangidwa ndi Chitsulo Chozungulira ChoziziraAmapangidwa ndi zitsulo zodulidwa kale, zathyathyathya zomwe zimapangidwa kukhala ma profiles olumikizana pogwiritsa ntchito ma rollers ozizira—palibe kutentha kwambiri komwe kumayikidwa popanga. Njira yozungulira yozizira imadalira kusinthasintha kwa chitsulo kutentha kwa chipinda, zomwe zimapangitsa kuti chikhale choyenera kupanga ma profiles opepuka komanso ofanana, ngakhale kuti zingayambitse kupsinjika pang'ono kwamkati komwe kumafuna kukonzedwa pambuyo pake (monga kunyowa) pazinthu zina zolemera kwambiri.

Magwiridwe antchito ndi kapangidwe ka mitundu iwiri ya milu ya pepala lachitsulo

Magwiridwe antchito ndi mawonekedwe a kapangidwe kake zimasiyanitsa mitundu iwiriyi. Mapepala okulungidwa ndi kutentha amapereka mphamvu komanso kulimba kwapadera: kapangidwe kawo kokulungidwa ndi kutentha kamapereka mphamvu zambiri zokoka, mphamvu zokolola, komanso kukana kugwedezeka, zomwe zimapangitsa kuti zikhale zoyenera ntchito zolemera komanso za nthawi yayitali. Mwachitsanzo, mapepala okulungidwa ndi kutentha nthawi zambiri amakondedwa m'mapulojekiti ofukula mozama (komwe mapepalawo ayenera kupirira kupsinjika kwakukulu kwa nthaka) kapena nyumba zodzitetezera za m'mphepete mwa nyanja (zomwe zimakumana ndi nyengo yoipa komanso dzimbiri la m'nyanja). Akamakonzedwa ndi zokutira (monga epoxy kapena zinc), mapepala okulungidwa ndi kutentha amaperekanso kukana dzimbiri bwino, chifukwa kapangidwe ka zinthu kofanana kamatsimikizira kuti gawo loteteza limamatira mofanana. Mapepala okulungidwa ndi ozizira, kumbali ina, ndi opepuka komanso otsika mtengo kwambiri pa ntchito zakanthawi kapena zapakati. Kulemera kwawo kochepa kumapangitsa kuti mayendedwe ndi kukhazikitsa zikhale zosavuta—zofuna zida zochepa ndi ntchito—kuzipangitsa kukhala zoyenera kuthandizira nyumba kwakanthawi kochepa, makoma osakhalitsa, kapena mapulojekiti a pansi pa nyumba, komwe mphamvu zonyamula katundu wambiri si chinthu chofunikira kwambiri. Ngakhale kuti mphamvu zawo ndi zochepa poyerekeza ndi njira zina zomwe amagwiritsa ntchito pozitentha, kupita patsogolo kwaposachedwa kwa ukadaulo wopanga zinthu zozizira (monga zitsulo zamphamvu kwambiri) kwawonjezera kugwiritsidwa ntchito kwawo m'nyumba zosakhalitsa.

Mtengo ndi kupezeka kwa mitundu iwiri ya milu ya mapepala achitsulo

Mtengo ndi kupezeka kwake ndi zinthu zofunika kwambiri posankha pakati pa ziwirizi. Mapepala a Zitsulo Ozungulira Opangidwa ndi Cold Formed nthawi zambiri amakhala ndi mtengo wotsika wapatsogolo, chifukwa njira yozungulira yozizira imakhala yogwiritsa ntchito mphamvu zambiri, imafuna zida zapadera zochepa, ndipo imapanga zinyalala zochepa poyerekeza ndi kuzunguliza kotentha. Amapezekanso mosavuta m'makulidwe wamba, okhala ndi nthawi yochepa yopangira—yofunikira kwambiri pamapulojekiti omwe ali ndi nthawi yochepa. Mapepala a Zitsulo Ozungulira Otentha, mosiyana, ali ndi mtengo wokwera wopanga chifukwa cha njira yotenthetsera yomwe imagwiritsa ntchito mphamvu zambiri komanso kufunikira kwa makina ovuta kwambiri ozunguliza. Ma profiles apadera (opangidwira zofunikira zapadera za polojekiti) amawonjezeranso mtengo wawo ndi nthawi yawo yoyambira. Komabe, kulimba kwawo kwa nthawi yayitali nthawi zambiri kumathetsa ndalama zambiri zoyambira: m'nyumba zokhazikika, Mapepala a Zitsulo Ozungulira Otentha amafunikira kukonza kochepa ndipo amakhala ndi moyo wautali wautumiki, zomwe zimachepetsa ndalama zogwirira ntchito pakapita nthawi.
