Kwishishini lokukhupha i-aluminium, xa iprofayili iphuma kwi-die kumaqondo obushushu afikelela kwi-500–550°C kuphawula inqaku elibalulekileyo kwinkqubo yemveliso. Kweli nqanaba, i-aluminium eshushu, eqinileyo nengaqinanga isengozini enkulu yokonakala komphezulu, ukuguquka, kunye nokukrwela—iziphene ezinokwenza imveliso yokugqibela ingasetyenziswa kwizicelo ezinexabiso eliphezulu ezifana nezixhobo zokwakha ezidityanisiweyo okanye iindawo zemoto.

A ibhande lokuhambisa elivalekileyo le-aluminium extrusionayisiyondlela nje yokuthutha; yinxalenye ebalulekileyo ekhusela ukuthembeka kwemveliso, inciphisa ixesha lokungasebenzi, kwaye iphucula imveliso. Ngokungafaniyo nee-slats zesinyithi zemveli okanye iibhanti zelaphu, iibhanti zefelt ezingapheliyo zibonelela ngomxube owahlukileyo wokumelana nobushushu, ukhuseleko lomphezulu, kunye nozinzo olulinganayo.

Kubaphathi bezityalo, iinjineli zolondolozo, kunye neengcali zokuthenga, ukukhetha ibhande lokuhambisa i-felt elifanelekileyo—nokuba yi-PBO, i-Kevlar, i-Nomex, okanye i-Polyester—kuchaphazela ngokuthe ngqo amanqanaba enkunkuma, ubomi bokufa, kunye nokusebenza kakuhle kwezixhobo (OEE). Esi sikhokelo sibonelela ngohlalutyo olunzulu lweebhande ze-felt ezisetyenziswa kwi-aluminium extrusion, isayensi yezinto ezibonakalayo, iindawo zokusetyenziswa, kunye neenkcukacha zobugcisa ukukunceda wenze isigqibo sokuthenga esinolwazi.

Ukuqonda Inkqubo Yokukhupha: Iindawo Zobushushu kunye Neemfuno

Itafile yokuphuma, apho iiprofayili zithuthwa khona kwaye zipholiswe, yahlulwe kwiindawo ezahlukeneyo zobushushu. Isigaba ngasinye sifuna uhlobo oluthile lwebhanti yefelt ukuze ikwazi ukusingatha imithwalo eyahlukeneyo yobushushu kunye noxinzelelo loomatshini.

Ukukhethwa kwezinto: i-PBO, i-Kevlar, i-Nomex, kunye ne-Polyester

Ukukhethwa kwezinto zefayibha kuchaza ukusebenza kwebhanti, ubomi bayo, kunye nokusebenza kwayo kakuhle. Nantsi inkcazelo yezinto ezine eziphambili ezisetyenziswa kwiibhanti zefelthi ze-aluminium extrusion:

1. I-PBO (iPolybenzoxazole) – Indawo yobushushu obuphezulu kakhulu

I-PBO (edla ngokubizwa ngokuba yiZylon) imele incopho yokumelana nobushushu kwiibhanti zefelt. Yenzelwe ngokukodwa imeko-bume enzima emva nje komatshini wokushicilela we-extrusion.

• Ukumelana nobushushu: Ukuya kuthi ga kwi-600°C rhoqo. Le yeyona nto ikwaziyo ukumelana nobushushu bokuqala ngaphandle kokuwohloka okanye ukutshisa umphezulu we-aluminiyam.
• Ukusetyenziswa: Iipress ezinomthamo ophezulu (>2000T), iiprofayili ezinkulu nezintsonkothileyo, kunye "nesiphelo esingaphambili" setafile yokubaleka.
• Iingenelo: Ukumelana okungaqhelekanga kobushushu, ubude obuphantsi, kunye nokungabikho kophawu lomphezulu. Iibhanti zePBO zihlala zinombala o-orenji okanye omdaka.
• Iinkcukacha eziphambili: Ubukhulu buqala kwi-4mm ukuya kwi-12mm; ububanzi obuqhelekileyo bufikelela kwi-2,200mm.

2. IKevlar (iPara-Aramid) – Indawo yoBushushu obuPhezulu

IKevlar inzima kakhulu kumgca wokukhupha, inika ulungelelwaniso lokumelana nobushushu obuphezulu, ukuqina, kunye nokusebenza kakuhle kweendleko.

• Ukumelana nobushushu: Ukuya kuthi ga kwi-480–500°C (incopho/ixesha elifutshane) kunye ne-~200°C ngokuqhubekayo.
• Ukusetyenziswa: Iitafile zokupholisa eziphambili nezesibini, iitafile zokuphatha/zokudlulisa.
• Iingenelo: Ukumelana nokukrweleka okugqwesileyo kunye namandla okutsalwa. Ithintela ukunwebeka phantsi kwemithwalo enzima. Iibhanti zeKevlar eziqhelekileyo zihlala zityheli.
• Iinkcukacha eziphambili: Zifumaneka ngobukhulu obuphakathi kwe-5mm ukuya kwi-14mm kunye nobubanzi obufikelela kwi-3,000mm.

3. I-Nomex (iMeta-Aramid) – Indawo yoBushushu obuPhakathi

I-Nomex isetyenziswa apho amaqondo obushushu esabalulekile kodwa engekho mandundu, njengakwimisebenzi esezantsi komlambo.

• Ukumelana nobushushu: Ukuya kuthi ga kwi-280°C.
• Ukusetyenziswa: Iindawo zokubeka i-post-stretcher, iitafile zesarha, kunye nokudluliselwa kwangaphambili.
• Iingenelo: Uzinzo oluhle lobushushu kunye nesakhiwo esingabizi kakhulu. Ihlala imhlophe ngombala. Ifanelekile kwiiprofayili ezininzi ze-extrusion ezisemgangathweni.
• Iinkcukacha eziphambili: Ubuninzi buhlala buphakathi kwe-0.15 ukuya kwi-0.45 g/cm³.

4. I-Polyester – Indawo yobushushu obuphantsi

Iibhanti zepolyester ziyindlela engabizi kakhulu kwizigaba zokugqibela zomgca wokukhupha.

• Ukumelana nobushushu: Ukuya kuthi ga kwi-150–180°C.
• Ukusetyenziswa: Iitafile ezisajiweyo, iindawo zokubeka izinto, indawo yokugcina, kunye nemigca yokulungiselela i-anodizing.
• Iingenelo: Ixabiso liphantsi, kulula ukuyitshintsha, kwaye inika umphezulu ongaphawuliyo. Ngokwesiqhelo iba beige okanye imhlophe.
• Iinkcukacha eziphambili: Zifumaneka ngobukhulu obufana ne-3mm, 5mm, 6mm, kunye ne-8mm.

Iingenelo ezi-5 ezibalulekileyo zeBelts zeFelt ezingapheliyo ezingenamthungo

Ukukhusela iiprofayili ze-aluminiyam ezixabisekileyo kwiziphene, ibhanti ngokwayo kufuneka ingabi nasiphako. Nantsi isizathu sokuba ulwakhiwo olungenasiphelo lwefelt enenaliti luphumelela kunezinye iindlela ezidityanisiweyo okanye ezidityanisiweyo:

• Akukho ziphene kumphezulu (Akukho kukrweleka): Inzuzo ephambili ngumphezulu ogudileyo, ongenazimpawu othintela imikrwelo kunye nokuqhekeka kwi-extrusions ethambileyo, ephezulu (umz., iindawo ezikhazimlisiweyo okanye ezifakwe i-anodized). Oku kuqinisekisa imveliso esemgangathweni ophezulu kwaye kunciphisa amazinga okukrweleka.
• Ukususwa kwaManqaku Abuthathaka: Iibhanti ezibotshelelweyo okanye ezidityanisiweyo zenza "indawo ebuthathaka" enokuphulukana nomgangatho phantsi kobushushu obuphezulu kunye noxinzelelo. Iibhanti ezingenamthungo zisasaza uxinzelelo ngokulinganayo, nto leyo eyandisa kakhulu ubomi bokusebenza kwebhanti.
• Ukuxinana Okuphezulu Nobude Obuphantsi: Iibhanti zefelthi ezinenaliti, ingakumbi ezo ziqiniswe ngeefayibha ze-aramid (Kevlar), azinazo iintambo ezininzi. Oku kugcina umkhondo webhanti kunye noxinzelelo oluhambelanayo, kuqinisekisa isantya semveliso esizinzileyo kunye nokunciphisa iimfuno zokugcinwa.
• Ukumelana nokuGqoka okuPhezulu kunye nokuGqoka: Ulwakhiwo lwefayibha enoxinano oluphezulu lwefeli ebhobozwe ngenaliti lubonelela ngokumelana okuhle kakhulu nokungqubana okuvela kwiikona ezibukhali kunye nemithwalo enzima, okuqinisekisa ubomi obude benkonzo nokuba isetyenziswa rhoqo.
• Uzinzo kunye nokuHamba kobushushu: I-Felt isebenza njengesigqubuthelo sendalo, ivumela inkqubo yokupholisa elawulwayo. Ithintela ukubola komphezulu kunye "neendawo ezishushu" kwiprofayili.

Iinkcukacha zobugcisa ekufuneka ziqwalaselwe

Xa uthenga ibhanti yokuhambisa yefelthi yomgca wakho wokukhupha, qiniseka ukuba uqinisekisa ezi parameter zobugcisa zilandelayo nomthengisi wakho:

• Ububanzi: Ngokwesiqhelo isuka kwi-20mm ukuya kwi-3,000mm kuxhomekeke kubukhulu bokucinezela kunye nobukhulu beprofayili.
• Ubude (Ukujikeleza): Buyahluka kakhulu, ukusuka kwi-1,780mm ukuya kwi-25,000mm kwimigca eqhelekileyo, kwaye ezinye iinkqubo zifuna ukuya kuthi ga kwi-40,000mm.
• Ubukhulu: Uluhlu oluqhelekileyo luqala kwi-3mm ukuya kwi-14mm. Kwiinkqubo ezinzima, imveliso eyenzelwe wena ukuya kuthi ga kwi-80mm inokwenzeka.
• Uxinano: Iqala kwi-0.15 ukuya kwi-0.45 g/cm³; uxinano oluphezulu ngokubanzi lubonisa ukumelana nokuguguleka okungcono kunye nokuziphatha kweseti yokucinezelwa.
• Unyango Lomphezulu: Iindlela ezahlukeneyo ziquka ukugqitywa kwe-PU (polyurethane) ukuze umphezulu ube mtyibilizi, ukugqitywa okungenazimo ukuze kuthintelwe ukutsala uthuli, kunye nokuvalwa komphetho ukuze kuthintelwe ukuqhekeka
