Embonini yokukhipha i-aluminium, lapho iphrofayili iphuma emshinini wokushisa ofinyelela ku-500–550°C kuphawula iphuzu elibalulekile enqubweni yokukhiqiza. Kulesi sigaba, i-aluminium eshisayo, eqinile kancane isengozini enkulu yokulimala kwendawo, ukuguquka, kanye nokuklwebheka—iziphambeko ezingenza umkhiqizo wokugcina ungasetshenziswa ezinhlelweni zenani eliphezulu njengezingxenye zokwakha ezi-anodized noma izingxenye zezimoto.

A ibhande lokuhambisa elizwayo le-aluminium extrusionkungaphezu nje kwendlela yokuthutha; kuyingxenye ebalulekile evikela ubuqotho bomkhiqizo, inciphisa isikhathi sokungasebenzi, futhi ithuthukise ukusebenza kahle. Ngokungafani nama-slats ensimbi noma amabhande endwangu endabuko, amabhande e-felt angenasinaliti anikeza inhlanganisela eyingqayizivele yokumelana nokushisa, ukuvikelwa kobuso, kanye nokuqina kobukhulu.

Kubaphathi bezitshalo, onjiniyela bokulungisa, kanye nochwepheshe bokuthenga, ukukhetha ibhande lokuhambisa elifanele le-felt—kungakhathaliseki ukuthi i-PBO, i-Kevlar, i-Nomex, noma i-Polyester—kuthinta ngqo amazinga okulahla, impilo yokufa, kanye nokusebenza kahle kwemishini iyonke (OEE). Lo mhlahlandlela unikeza ukuhlaziywa okujulile kwamabhande e-felt asetshenziswa ekukhishweni kwe-aluminium, isayensi yezinto ezibonakalayo, izindawo zokusetshenziswa, kanye nezincazelo zobuchwepheshe ukukusiza wenze isinqumo sokuthenga esinolwazi.

Ukuqonda Inqubo Yokukhipha: Izindawo Zokushisa Nezidingo

Ithebula lokuphelelwa yisikhathi, lapho amaphrofayili athuthwa futhi apholiswa khona, lihlukaniswe ngezindawo zokushisa ezihlukile. Isigaba ngasinye sidinga uhlobo oluthile lwebhande le-felt ukuze libhekane nemithwalo yokushisa ehlukahlukene kanye nokucindezeleka komshini.

Ukukhethwa Kokuqukethwe: I-PBO, i-Kevlar, i-Nomex, ne-Polyester

Ukukhethwa kwezinto zefayibha kuchaza ukusebenza kwebhande, isikhathi sokuphila, kanye nokusebenza kahle kwezindleko. Nansi incazelo yezinto ezine eziyinhloko ezisetshenziswa emabhandeni e-felt extrusion e-aluminium:

1. I-PBO (i-Polybenzoxazole) – Indawo Yokushisa Okuphezulu Kakhulu

I-PBO (evame ukubizwa ngokuthi i-Zylon) imelela isiqongo sokumelana nokushisa kwamabhande e-felt. Yenzelwe ngqo indawo enzima ngokushesha ngemva komshini wokucindezela i-extrusion.

• Ukumelana Nokushisa: Kufika ku-600°C njalo. Lena yiyo kuphela into ekwazi ukumelana nokushisa kokuqala ngaphandle kokuwohloka noma ukushisa ubuso be-aluminium.
• Isicelo: Ukucindezela okunamandla aphezulu (>2000T), amaphrofayili amakhulu nayinkimbinkimbi, kanye "nengxenye engaphambili" yetafula lokuqalisa.
• Izinzuzo: Ukumelana nokushaqeka okumangalisayo kokushisa, ukunwebeka okuphansi, futhi akukho zimpawu zobuso. Amabhande e-PBO avame ukuba nombala ohlukile we-orenji noma onsundu.
• Imininingwane Ebalulekile: Ubukhulu busukela ku-4mm kuya ku-12mm; ububanzi obujwayelekile bufika ku-2,200mm.

2. I-Kevlar (i-Para-Aramid) – Indawo Yokushisa Okuphezulu

I-Kevlar iyindlela yokusebenza emugqeni wokukhipha, inikeza ibhalansi yokumelana nokushisa okuphezulu, ukuqina, kanye nokusebenza kahle kwezindleko.

• Ukumelana Nokushisa: Kufika ku-480–500°C (isiqongo/isikhathi esifushane) kanye no-~200°C okuqhubekayo.
• Ukusetshenziswa: Amatafula okupholisa ayisisekelo nawesibili, amatafula okuphatha/okudlulisa.
• Izinzuzo: Ukumelana okuhle kakhulu nokuklwebheka kanye namandla okunamathela. Kuvimbela ukunwebeka ngaphansi kwemithwalo esindayo. Amabhande ajwayelekile e-Kevlar avame ukuba phuzi.
• Imininingwane Eyinhloko: Itholakala ngokuvamise ngobukhulu obungu-5mm kuya ku-14mm kanye nobubanzi obufika ku-3,000mm.

3. I-Nomex (i-Meta-Aramid) – Indawo Yokushisa Okumaphakathi

I-Nomex isetshenziswa lapho amazinga okushisa esabalulekile kodwa engekho aphezulu kakhulu, njengemisebenzi engezansi komfula.

• Ukumelana Nokushisa: Kufika ku-280°C.
• Ukusetshenziswa: Izindawo zokwelula ngemuva, amatafula okusaha, kanye nokudluliselwa kokusika kusengaphambili.
• Izinzuzo: Ukuqina okuhle kokushisa kanye nesakhiwo esiphansi sezindleko. Ngokuvamile kumhlophe ngombala. Kufanelekela amaphrofayili amaningi e-extrusion ajwayelekile.
• Imininingwane Eyinhloko: Ubuningi buvame ukusuka ku-0.15 kuya ku-0.45 g/cm³.

4. I-Polyester – Indawo Yokushisa Okuphansi

Amabhande e-polyester ayisinqumo esingabizi kakhulu sezigaba zokugcina zomugqa wokukhipha.

• Ukumelana Nokushisa: Kufika ku-150–180°C.
• Ukusetshenziswa: Saw amatafula, izindawo zokubeka izinto, indawo yokugcina izinto kanye nemigqa yokulungiselela i-anodizing.
• Izinzuzo: Izindleko eziphansi, kulula ukuyifaka esikhundleni, futhi inikeza indawo engabonakali. Ngokuvamile inombala oluhlaza okwesibhakabhaka noma omhlophe.
• Imininingwane Eyinhloko: Itholakala ngokuvamise ngobukhulu obufana no-3mm, 5mm, 6mm, kanye no-8mm.

Izinzuzo Ezi-5 Ezibalulekile Zamabhande E-Felt Angenamthungo

Ukuze kuvikelwe amaphrofayili e-aluminium anenani eliphezulu ezifweni, ibhande ngokwalo kumelwe lingabi naphutha. Nasi isizathu esenza ukwakhiwa kwefelthi enesinaliti kuphumelela kakhulu kunezinye izindlela eziboshwe noma ezihlanganisiwe:

• Akukho Maphutha Omphezulu (Akunamihuzuko): Inzuzo eyinhloko indawo ebushelelezi, engenamaki evimbela imihuzuko kanye nokuqhekeka ezintweni ezithambile, eziphelele kakhulu (isb., izindawo ezipholishiwe noma ezifakwe i-anodized). Lokhu kuqinisekisa umkhiqizo wekhwalithi ephezulu futhi kunciphisa amazinga okulahla.
• Ukususwa Kwamaphuzu Abuthakathaka: Amabhande aboshwe noma ahlanganisiwe adala "indawo ebuthakathaka" evame ukwehluleka ngaphansi kwamazinga okushisa aphezulu kanye nokucindezeleka. Amabhande angenamthungo asabalalisa ukucindezeleka ngokulinganayo, okwandisa kakhulu isikhathi sokusebenza kwebhande.
• Ukuthambekela Okuphezulu Nokwelula Okuphansi: Amabhande e-felt anenaliti, ikakhulukazi lawo aqiniswe ngemicu ye-aramid (i-Kevlar), abonisa ukunwebeka okuncane. Lokhu kugcina ukulandelela nokucindezela kwebhande okuqhubekayo, kuqinisekisa isivinini sokukhiqiza esizinzile kanye nezidingo zokulungisa ezincishisiwe.
• Ukumelana Nokugqokwa Okuphezulu Nokuguguleka: Isakhiwo sefayibha esinobukhulu obuphezulu sefeyinti ebhobozwe ngenaliti sinikeza ukumelana okuhle kakhulu nokuguguleka okuvela emaphethelweni abukhali kanye nemithwalo esindayo, okuqinisekisa impilo yenkonzo ende ngisho nangaphansi kokusebenza okuqhubekayo.
• Ukuzinza Nokuqhutshwa Kokushisa: I-Felt isebenza njengesivikelo semvelo, ivumela inqubo yokupholisa elawulwayo. Ivimbela ukubola komphezulu kanye "nezindawo ezishisayo" kuphrofayili.

Imininingwane Yobuchwepheshe Okufanele Uyicabangele

Uma uthenga ibhande lokuhambisa eliyi-felt lomugqa wakho wokukhipha, qiniseka ukuthi uqinisekisa lezi zinhlaka zobuchwepheshe ezilandelayo nomhlinzeki wakho:

• Ububanzi: Ngokuvamile busukela ku-20mm kuya ku-3,000mm kuye ngosayizi wokucindezela kanye nobukhulu bephrofayili.
• Ubude (Isiyingi): Buyahlukahluka kakhulu, kusukela ku-1,780mm kuya ku-25,000mm emigqeni ejwayelekile, kanti ezinye izinhlelo zidinga kufika ku-40,000mm.
• Ubukhulu: Ububanzi obujwayelekile bungu-3mm kuya ku-14mm. Ngezinhlelo zokusebenza ezisindayo, imikhiqizo eyenziwe ngokwezifiso efinyelela ku-80mm ingenzeka.
• Ubuningi: Busukela ku-0.15 kuya ku-0.45 g/cm³; ubuningi obuphezulu ngokuvamile bubonisa ukumelana okungcono kokuguguleka kanye nokuziphatha kwesethi yokucindezela.
• Ukwelashwa Komphezulu: Izinketho zifaka phakathi ukuqeda kwe-PU (polyurethane) ukuze kube bushelelezi obuthuthukisiwe bomphezulu, ukuqeda okungahambi kahle ukuze kuvinjelwe ukukhanga kothuli, kanye nokuvala unqenqema ukuze kuvinjelwe ukuqhekeka
