Muindasitiri yekubvisa aluminium, kana chimiro chabuda muchinhu chacho patembiricha inosvika 500–550°C, chinhu chakakosha pakugadzirwa kwacho. Panguva ino, aluminium inopisa, isina simba zvakanyanya inogona kukuvara pamusoro, kushanduka, uye kukwenya—zvikanganiso zvinogona kuita kuti chigadzirwa chekupedzisira chisakwanise kushandiswa pakushandisa zvinhu zvinokosha zvakaita sezvinhu zvekuvaka zvakazorwa kana zvikamu zvemotokari.

A akanzwa bhandi rekufambisa realuminium extrusionHazvisi kungofambisa chete; chinhu chakakosha chinodzivirira kunaka kwechigadzirwa, chinoderedza nguva yekushanda, uye chinogadzirisa mashandiro acho. Kusiyana nemasimbi ekare kana mabhandi ejira, mabhandi efelt ane needled asingaperi anopa musanganiswa wakasiyana wekudzivirira kupisa, dziviriro pamusoro, uye kugadzikana kwehukuru.

Kune vatariri vemafekitori, mainjiniya ekugadzirisa, uye nyanzvi dzekutenga, kusarudza bhandi rekufambisa rakakodzera refelt—ingava PBO, Kevlar, Nomex, kana Polyester—kunokanganisa zvakananga mwero wezvimedu, hupenyu hwekufa, uye kushanda zvakanaka kwemidziyo yese (OEE). Gwaro iri rinopa ongororo yakadzama yemabhendi efelt anoshandiswa mukuwedzera aluminium, sainzi yezvinhu, nzvimbo dzekushandisa, uye hunyanzvi hwekukubatsira kuita sarudzo yekutenga neruzivo.

Kunzwisisa Maitiro Ekubvisa Mvura: Nzvimbo Dzekupisa Nezvinodiwa

Tafura yekubuda kwemhepo, uko maprofile anotakurwa uye anotonhodzwa, yakakamurwa kuita nzvimbo dzakasiyana dzekupisa. Danho rega rega rinoda rudzi rwakasiyana rwebhandi refelt kuti rigone kubata zvinhu zvakasiyana-siyana zvekupisa uye kumanikidzwa kwemagetsi.

Kusarudzwa Kwezvinhu: PBO, Kevlar, Nomex, uye Polyester

Kusarudzwa kwezvinhu zvefaibha kunotsanangura mashandiro ebhandi, hupenyu hwebasa, uye kushanda zvakanaka kwemari. Heino kupatsanurwa kwezvinhu zvina zvikuru zvinoshandiswa mumabhandi efelt ekuwedzera aruminiyamu:

1. PBO (Polybenzoxazole) – Nzvimbo yekupisa kwakanyanya

PBO (inowanzozivikanwa seZylon) inomiririra kukwirira kwekudzivirira kupisa kwemabhande efelt. Yakagadzirwa zvakananga kuti ishandiswe munzvimbo dzakaoma mushure mekudzvanywa kweextrusion.

• Kuramba Kupisa: Kusvika 600°C nguva dzose. Ichi ndicho chinhu chega chinogona kutsungirira kupisa kwekutanga pasina kuora kana kupisa pamusoro pearuminiyamu.
• Mashandisirwo: Madhindindi ane simba guru (>2000T), mapurofayiri makuru uye akaomarara, uye "kumberi" kwetafura yekumhanya.
• Zvakanakira: Inodzivirira kupisa zvakanyanya, hainyanyi kureba, uye haina mavara pamusoro. Mabhandi ePBO anowanzova neruvara rweorenji kana brown.
• Zvidimbu Zvikuru: Ukobvu hunobva pa4mm kusvika 12mm; upamhi hwakajairika hunosvika 2,200mm.

2. Kevlar (Para-Aramid) – Nzvimbo yekupisa kwakanyanya

Kevlar ibasa rakaoma mumutsara wekubvisa simbi, ichipa chiyero chekudzivirira kupisa kwakanyanya, kugara kwenguva refu, uye kushanda zvakanaka kwemari.

• Kuramba Kupisa: Kusvika 480–500°C (yakanyanya/yenguva pfupi) uye ~200°C isingaperi.
• Mashandisirwo: Matafura ekutonhodza ekutanga neechipiri, matafura ekubata/kutamisa.
• Zvakanakira: Inodzivirira kukwenywa zvakanyanya uye yakasimba pakukwenya. Inodzivirira kurebesa kana yakaremerwa. Mabhandi eKevlar akajairika anowanzo kuve eyero.
• Zvidimbu Zvikuru: Inowanikwa muukobvu hwe5mm kusvika 14mm uye upamhi hunosvika 3,000mm.

3. Nomex (Meta-Aramid) – Nzvimbo yeTembiricha yepakati

Nomex inoshandiswa munzvimbo dzine tembiricha dzakanyanya kukosha asi dzisina kunyanya kunyanyisa, senge munzvimbo dziri pasi pemvura.

• Kuramba Kupisa: Kusvika 280°C.
• Mashandisirwo: Nzvimbo dzinoshandiswa pakutambanudza, matafura ekucheka, uye kutamiswa kwekucheka usati wacheka.
• Zvakanakira: Kugadzikana kwakanaka kwekupisa uye chimiro chinodhura zvishoma. Kazhinji chichena muruvara. Chinokodzera ma profiles mazhinji e extrusion akajairwa.
• Zvidimbu Zvikuru: Kuwanda kwechinhu kunowanzova pakati pe0.15 ne0.45 g/cm³.

4. Polyester - Nzvimbo yekupisa kushoma

Mabhandi epolyester ndiwo sarudzo inodhura zvishoma pamatanho ekupedzisira emutsara wekubvisa jira.

• Kuramba Kupisa: Kusvika 150–180°C.
• Mashandisirwo: Matafura akachekwa, nzvimbo dzekuisa zvinhu, nzvimbo dzekuchengetera, uye mitsetse yekugadzirira anodizing.
• Zvakanakira: Mutengo wakaderera, zviri nyore kuchinja, uye hazviratidzike zvakanaka. Kazhinji bhuruu kana chena.
• Zvidimbu Zvikuru: Inowanikwa muhukobvu hwakaita se3mm, 5mm, 6mm, uye 8mm.

Mabhenefiti mashanu Akakosha Emabhandi Ekunze Asina Musono

Kuti bhandi ridzivirire ma profiles earuminiyamu anokosha kubva pakukanganisika, rinofanira kunge risina chikanganiso. Heino chikonzero nei kuvakwa kwefelt isina needled kusingapere kunopfuura dzimwe nzira dzakasungirirwa kana dzakasungirirwa:

• Hapana Zvikanganiso Pamusoro (Hazvina Kukwenywa): Chinhu chikuru ndechekuti nzvimbo yacho yakatsetseka, isina mavara inodzivirira kukwenywa uye kutsemuka pazvinobuda zvakapfava, zvepamusoro-soro (semuenzaniso, nzvimbo dzakakwenenzverwa kana dzakazorwa). Izvi zvinoita kuti pave nekubuda kwemhando yepamusoro uye zvinoderedza mwero wezvimedu zvakachekwa.
• Kubvisa Nzvimbo Dzisina Simba: Mabhandi akasungirirwa kana kuti akasungirirwa anogadzira "nzvimbo isina simba" iyo inogona kukundikana kana tembiricha yakakwira uye kushushikana. Mabhandi asina musono anoparadzira kushushikana zvakaenzana, zvichiwedzera zvakanyanya hupenyu hwebhandi.
• Kubata Kwakanyanya Uye Kureba Kwakaderera: Mabhandi efelt ane tsono, kunyanya ayo akasimbiswa ne aramid fibers (Kevlar), haatambanudzike zvakanyanya. Izvi zvinochengetedza kuteverwa kwebhandi nguva dzose uye kusimba, zvichiita kuti kugadzirwa kurambe kwakasimba uye kuderedza zvinodiwa pakugadzirisa.
• Kuramba Kupfeka Uye Kusapfeka Kwakanaka: Chimiro chefibre chakanyanya kusimba chefelt yakaboorwa netsono chinopa simba rakanaka pakukweshana kubva kumipendero yakapinza nemitoro inorema, zvichiita kuti igare kwenguva refu kunyangwe ichishanda nguva dzose.
• Kugadzikana kweThermal & Kufambisa: Felt inoshanda semushonga wechisikigo, ichibvumira maitiro ekutonhodza anodzorwa. Inodzivirira oxidation yepamusoro uye "nzvimbo dzinopisa" paprofile.

Magadzirirwo Ehunyanzvi Ekufunga Nezvedu

Paunenge uchitenga bhandi rekufambisa refelt retambo yako yekuburitsa, iva nechokwadi chekuti waongorora zvinotevera zvehunyanzvi nemutengesi wako:

• Upamhi: Kazhinji inotangira pa20mm kusvika 3,000mm zvichienderana nehukuru hwemuchina wekudzvanya uye saizi yeprofile.
• Kureba (Kutenderera): Kunosiyana-siyana, kubva pa1,780mm kusvika 25,000mm pamitsetse yakajairwa, uye mamwe masisitimu anoda kusvika 40,000mm.
• Ukobvu: Hurefu hwakajairika hunobva pa3mm kusvika 14mm. Kune mashandisirwo anorema, zvigadzirwa zvakagadzirwa zvinoenderana nezvinodiwa zvinosvika 80mm zvinogoneka.
• Kuwanda: Kunotangira pa 0.15 kusvika 0.45 g/cm³; kuwanda kwakanyanya kunoratidza kuti inodzivirira kupfeka zviri nani uye kuti inogona kudzvanywa zviri nani.
• Kurapa Pamusoro: Sarudzo dzinosanganisira kupedzisa kwePU (polyurethane) kuti pamusoro pave nekutsvedzerera, kupedzisa kusingachinji kudzivirira kukwezva guruva, uye kuvhara mucheto kudzivirira kupwanyika.
