Mekhoa ea ho itokisa le mathata a aluminium foam sandwich panels

Tokisetso ealiphanele tsa sandwich tsa aluminium foame arotsoe ka lihlopha tse peli ka kakaretso. Sehlopha sa pele ke ho lokisa foam ea aluminium pele, ebe o hokahanya foam ea aluminium le phanele ea tšepe ka mekhoa e fapaneng, joalo ka khokahano e entsoeng ka samente, mokhoa oa ho fafatsa ka holim'a mocheso, le khokahano ea welding. Mofuta oa bobeli ke oa ho lokisa 'mele o entsoeng esale pele oa aluminium foam sandwich panel,' me joale 'mele o entsoeng esale pele o futhumatsoa ho etsa foam ea mantlha,' me foam e pholisoe ka mor'a ho phethoa ha foam e leng aluminium foam sandwich panel. Mekhoa e tloaelehileng ea ho itokisa e kenyelletsa ho hatella ho chesang - mokhoa oa phofo oa metallurgy foaming, rolling - coating - foaming mokhoa, joalo-joalo.

1. Khokahano ea glue

Gluing e bolela mokhoa oa ho etsa liphanele tsa sandwich ka ho kopanya foam ea aluminium ho liphanele tsa tšepe tse nang le likhomaretsi tse loketseng. Ts'ebetso ea gluing e amohela khokahano ea 'mele ho lokisa phanele ea sandwich,' me mokhoa ona o na le melemo ea ts'ebetso e bonolo le ho nepahala ha tlhahiso e phahameng. Leha ho le joalo, ka lebaka la litšobotsi tsa sebopeho sa porosity e phahameng eaaluminium foam, ho tlosoa ha litšila ka likoti tse holim'a foam ea aluminium ho batla ho le boima; ka mokhoa ona oa khokahanyo, phanele le lera la mantlha li khomaretsoe haholo-holo lithakong tsa aperture, 'me sebaka sa sebele sa maqhama se sebetsang se senyenyane, se fellang ka matla a tlaase a tlamahano ea sebopeho sa sandwich; sekhomaretsi se hloleha ho mocheso o phahameng kapa libakeng tse matla tse senyang, tse bakang karohano ea lera la mantlha ho tloha phanele le ho senyeha ha sebopeho.

2. Khokahano ea ho cheselletsa

Mekhoa ea ho tjheseletsa bakeng sa ho lokisa liphanele tsa foam aluminium sandwich e kenyelletsa laser beam welding, ultrasonic torsion welding, le brazing connections. Laser beam welding ke tšebeliso ea matla a phahameng a mocheso a laser ho lisebelisoa tsa phanele le ho qhibiliha ha foam aluminium bokaholimo, ho pholile ka mor'a hore likarolo tse peli li kopane hammoho, boemo ba ho tjheseletsa, le tatellano ea welding e bontšitsoeng ho Setšoantšo sa 1. Laser beam welding e nepahetse haholo 'me e ka atleha ka katleho. laola sebaka se qhibidihileng. Le hoja mokhoa ona o ka etsa ts'ebetso e tsoelang pele, katleho e tlaase, 'me matla a tlamahano ea sehlahisoa a boetse a tlaase. Molao-motheo oa ultrasonic torsion welding ke ho kopanya lisebelisoa tse peli hammoho ka matla a ultrasonic. Leha ho le joalo, mokhoa ona o hloka sebaka se itseng sa welding, 'me ho ke ke ha khoneha ho qeta ho cheselletsa libaka tsohle tse lebisitsoeng, tse fokotsang tšebeliso ea mokhoa ona tlhahiso ea sebele. Khokahano ea brazing e tla sitisoa ke lera le nang le oxidized ea foam aluminium, ka hona ho bohlokoa ho tlosa lesela le nang le oxidized, le ha o sebelisa theknoloji ea brazing ntle le ho phatloha ho hoholo.aluminium ea foamsandwich panels, mehato e meng ea anti-corrosion e lokela ho nkoa e le ho thibela li-alloys tse thehiloeng ho zinki le tse ling ho kopana le aluminium corrosion. Ho phaella moo, likarolo tse kopantsoeng ke mokhoa ona li na le li-prong tsa lesoba feela, kahoo matla a tlamahano a tla fokotseha.

3. Mokhoa oa ho fafatsa ka mocheso holim'a metsi

Mokhoa oa ho roala ka kakaretso o hloka tekanyo e phahameng ea ho bata ka holim'a karolo, kahoo mokhoa ona ha o tšoanelehe bakeng sa mehaho e rarahaneng haholoanyane. Ho fafatsa ka mocheso ke karolo ea theknoloji ea holim'a metsi, e fumanoang ka lithapo tse qhibilihisang kapa li-powders. Mokhoa ona o sebelisa jete ea moea ho potlakisa thepa e qhibilihisitsoeng le ho e fetisetsa ka holim'a karolo e tla koaheloa, e leng ho nolofalletsang ho sebetsana le likarolo tse nang le libopeho tse rarahaneng. Ka mokhoa ona, mohloli oa mocheso hangata ke arc ea motlakase. Leha ho le joalo, mokhoa ona o thata ho etsa indasteri ka lebaka la ho rarahana ha mokhoa ona.

4. Ho hatella ho chesang - mokhoa oa phofo oa metallurgy foaming

Ka mokhoa ona, phofo ea mantlha e sebelisetsoang ho phoka e qala ka har'a phanele, ebe e kenngoa ka har'a hlobo hammoho, ebe mochine oa hydraulic o sebelisoa ho sebelisa khatello e batang ho bona, ka mor'a moo likheo li tšoaroa ka 450 ℃. nako e ka bang 1 h ebe o hatelloa ho chesa ho fumana likheo tse entsoeng esale pele tse ka sebetsoang bakeng sa ho phophoma. Ka mor'a moo, preform e futhumatsoa 'me e phophoma ka hlobo e koetsoeng,' me karolo ea sandwich e fumanoa ka mor'a ho pholile. Ho ba teng ha hlobo ka mokhoa ona ho tla ba le mefokolo ho boholo ba sandwich e phethiloeng ea aluminium foam sandwich panel.

5. Rolling-coating-foaming mokhoa

Mokhoa ona ke phofo ea pele bakeng sa ho phophoma ka ho sebelisa mokhoa o nepahetseng oa ho roala ho etsa lisebelisoa tsa mantlha, ka mor'a hore phanele le lisebelisoa tsa mantlha tse entsoeng bakeng sa ho roala, ho roala, ho fumana likheo tse entsoeng esale pele, tse phophomang ka mor'a ho pholile ho fumana sebopeho se setle sa sandwich. phanele. Mokhoa ona oa ho lokisetsa lihlahisoa tse nang le matla a phahameng a tlamahano a ka hlokomela tlhahiso e tsoelang pele empa o hloka ho hlōla mathata a mabeli a theknoloji: e 'ngoe ke tlhokahalo ea ho fokotsa phofo,' me ea bobeli ke motsoako o sebetsang oa lisebelisoa tsa mantlha le ho roala phanele.
