Mu makampani opanga aluminiyamu, nthawi yomwe chithunzicho chikutuluka mu die kutentha kufika pa 500–550°C ndi nthawi yofunika kwambiri pakupanga. Pa siteji iyi, aluminiyamu yotentha, yolimba pang'ono imakhala yotetezeka kwambiri kuwonongeka pamwamba, kusinthika, ndi kukanda—zofooka zomwe zingapangitse kuti chinthu chomaliza chisagwiritsidwe ntchito pazinthu zamtengo wapatali monga zida zomangamanga zodzoladzola kapena zida zamagalimoto.

A lamba wolumikizira wa aluminiyamu extrusionSi njira yongoyendera zinthu zokha; ndi chinthu chofunikira kwambiri chomwe chimateteza umphumphu wa zinthu, chimachepetsa nthawi yogwira ntchito, komanso chimawongolera bwino ntchito yogwiritsidwa ntchito. Mosiyana ndi malamba achitsulo kapena nsalu, malamba osatha okhala ndi singano amapereka njira yapadera yolimbana ndi kutentha, kuteteza pamwamba, komanso kukhazikika kwa mawonekedwe.

Kwa oyang'anira mafakitale, mainjiniya okonza zinthu, ndi akatswiri ogula zinthu, kusankha lamba woyenera wa felt conveyor—kaya PBO, Kevlar, Nomex, kapena Polyester—kumakhudza mwachindunji kuchuluka kwa zinyalala, moyo wa die, komanso kugwira ntchito bwino kwa zida zonse (OEE). Bukuli limapereka kusanthula kwakuya kwa malamba a felt omwe amagwiritsidwa ntchito potulutsa aluminiyamu, kufotokozera bwino za sayansi ya zinthu, madera ogwiritsira ntchito, ndi zidziwitso zaukadaulo kuti zikuthandizeni kupanga chisankho chogula mwanzeru.

Kumvetsetsa Njira Yotulutsira Madzi: Malo Otentha ndi Zofunikira

Tebulo lotha ntchito, komwe ma profiles amanyamulidwa ndikuzizidwa, limagawidwa m'malo osiyanasiyana otentha. Gawo lililonse limafuna mtundu winawake wa lamba wofewa kuti ugwire ntchito zosiyanasiyana zotenthetsera komanso kupsinjika kwa makina.

Kusankha Zinthu: PBO, Kevlar, Nomex, ndi Polyester

Kusankha zinthu zopangidwa ndi ulusi kumatanthauza momwe lamba limagwirira ntchito, nthawi yake yogwira ntchito, komanso momwe limagwiritsira ntchito ndalama moyenera. Nayi njira yofotokozera zinthu zinayi zazikulu zomwe zimagwiritsidwa ntchito popanga malamba a felt opangidwa ndi aluminiyamu:

1. PBO (Polybenzoxazole) – Malo Otentha Kwambiri

PBO (yomwe nthawi zambiri imatchedwa Zylon) imayimira chipambano cha kukana kutentha kwa malamba a felt. Yapangidwa makamaka kuti igwirizane ndi malo ovuta omwe amatsatira makina osindikizira.

• Kukana Kutentha: Mpaka 600°C mosalekeza. Ichi ndi chinthu chokhacho chomwe chingathe kupirira kutentha koyamba popanda kuwononga kapena kuyatsa pamwamba pa aluminiyamu.
• Kugwiritsa Ntchito: Makina osindikizira amphamvu kwambiri (>2000T), ma profiles akuluakulu komanso ovuta, ndi "kutsogolo" kwa tebulo loyambira.
• Ubwino: Kukana kutentha kwambiri, kutalika kochepa, komanso kusakhala ndi chizindikiro pamwamba. Malamba a PBO nthawi zambiri amakhala ndi mtundu wa lalanje kapena bulauni.
• Zofunika Kwambiri: Kukhuthala kumasiyana kuyambira 4mm mpaka 12mm; m'lifupi mwachizolowezi ndi mpaka 2,200mm.

2. Kevlar (Para-Aramid) – Malo Otentha Kwambiri

Kevlar ndi chida chogwira ntchito bwino kwambiri chomwe chimagwiritsidwa ntchito potulutsa zinthu, chomwe chimapereka mphamvu yolimbana ndi kutentha kwambiri, kulimba, komanso kugwiritsa ntchito ndalama zochepa.

• Kukana Kutentha: Mpaka 480–500°C (pachimake/kanthawi kochepa) ndi ~200°C mosalekeza.
• Kugwiritsa Ntchito: Matebulo ozizira oyambira ndi achiwiri, matebulo ogwiritsira ntchito/kusamutsa.
• Ubwino: Kulimba kwambiri ndi kukana kukwawa komanso mphamvu yokoka. Kumaletsa kutalikirana pansi pa katundu wolemera. Malamba a Kevlar wamba nthawi zambiri amakhala achikasu.
• Zofunika Kwambiri: Zimapezeka nthawi zambiri m'makulidwe a 5mm mpaka 14mm ndi m'lifupi mpaka 3,000mm.

3. Nomex (Meta-Aramid) – Malo Otentha Kwambiri

Nomex imagwiritsidwa ntchito komwe kutentha kumakhala kofunikira koma osati koopsa kwambiri, monga momwe zimachitikira kumapeto kwa mtsinje.

• Kukana Kutentha: Mpaka 280°C.
• Kugwiritsa Ntchito: Malo osungira zinthu pambuyo pa chotambasula, matebulo ocheka, ndi kusamutsa zinthu musanadule.
• Ubwino: Kukhazikika bwino kwa kutentha ndi kapangidwe kotsika mtengo. Nthawi zambiri mtundu wake ndi woyera. Ndi yoyenera ma profiles ambiri odziwika bwino a extrusion.
• Zofunika Kwambiri: Kuchulukana nthawi zambiri kumakhala pakati pa 0.15 ndi 0.45 g/cm³.

4. Polyester - Malo Otentha Kwambiri

Malamba a polyester ndi chisankho chotsika mtengo pa magawo omaliza a mzere wotulutsira.

• Kukana Kutentha: Mpaka 150–180°C.
• Kugwiritsa ntchito: Matebulo odulidwa, malo osungiramo zinthu, malo osungiramo, ndi mizere yokonzekera anodizing.
• Ubwino: Mtengo wotsika, wosavuta kusintha, ndipo umapereka malo osalemba. Nthawi zambiri amakhala beige kapena oyera.
• Zofunikira: Zimapezeka nthawi zambiri m'makulidwe monga 3mm, 5mm, 6mm, ndi 8mm.

Ubwino 5 Wofunika Kwambiri wa Malamba Opanda Seamless Felt

Kuti muteteze ma profiles a aluminiyamu amtengo wapatali ku zolakwika, lamba lokha liyenera kukhala lopanda chilema. Ichi ndichifukwa chake kapangidwe ka needled felt kamagwira ntchito bwino kuposa njira zina zolumikizidwa kapena zolumikizidwa:

• Palibe Zolakwika Pamwamba (Zopanda Kukanda): Phindu lalikulu ndi malo osalala, osalemba omwe amaletsa kukanda ndi kusweka pa zinthu zofewa komanso zapamwamba (monga malo opukutidwa kapena odzola). Izi zimatsimikizira kutulutsa kwabwino kwambiri komanso kuchepetsa kuchuluka kwa zinyalala.
• Kuchotsa Nsonga Zofooka: Malamba omangiriridwa kapena olumikizidwa amapanga "nsonga yofooka" yomwe imatha kulephera kutentha kwambiri komanso kupsinjika. Malamba opanda msoko amagawa kupsinjika mofanana, zomwe zimawonjezera kwambiri nthawi yogwira ntchito ya lamba.
• Kulimba Kwambiri ndi Kutalikirana Kochepa: Malamba a felt okhala ndi singano, makamaka omwe amalimbikitsidwa ndi ulusi wa aramid (Kevlar), satambasuka kwambiri. Izi zimapangitsa kuti lamba lizitsatira bwino komanso kupsinjika, kuonetsetsa kuti kupanga kukuyenda bwino komanso kuchepetsa zosowa zosamalira.
• Kukana Kwabwino Kwambiri Kuvala ndi Kutupa: Kapangidwe ka ulusi wokhuthala kwambiri ka felt yobowoledwa ndi singano kamapereka kukana kwabwino kwambiri kukangana kuchokera m'mbali zakuthwa ndi katundu wolemera, zomwe zimapangitsa kuti ntchito ikhale yayitali ngakhale ikagwiritsidwa ntchito mosalekeza.
• Kukhazikika kwa Kutentha ndi Kuyendetsa: Felt imagwira ntchito ngati chotetezera kutentha chachilengedwe, chomwe chimalola njira yoziziritsira yolamulidwa. Imaletsa kukhuthala kwa pamwamba ndi "malo otentha" pa profil.

Mafotokozedwe Aukadaulo Oyenera Kuganizira

Mukagula lamba wolumikizira wa felt wa chingwe chanu chotulutsira, onetsetsani kuti mwatsimikizira magawo aukadaulo otsatirawa ndi omwe akukupatsani:

• M'lifupi: Nthawi zambiri zimakhala pakati pa 20mm ndi 3,000mm kutengera kukula kwa chosindikizira ndi kukula kwa mbiri.
• Kutalika (Mzere): Kusiyanasiyana kwambiri, kuyambira 1,780mm mpaka 25,000mm pa mizere yokhazikika, ndipo machitidwe ena amafuna mpaka 40,000mm.
• Kunenepa: Mtundu wamba ndi 3mm mpaka 14mm. Pa ntchito zolemera, zinthu zopangidwa mwamakonda mpaka 80mm ndizotheka.
• Kuchulukana: Kumasiyana kuyambira 0.15 mpaka 0.45 g/cm³; kuchulukana kwakukulu nthawi zambiri kumasonyeza kuti sichimawonongeka bwino komanso kuti sichimapanikizika bwino.
• Chithandizo cha Pamwamba: Zosankha zikuphatikizapo kumaliza kwa PU (polyurethane) kuti pamwamba pakhale posalala bwino, kumaliza kosagwirizana ndi static kuti fumbi lisakopeke, komanso kutseka m'mphepete kuti lisasweke.
