Uphando kunye noPhuhliso lweMetal Foam
Ukuphuhliswa kwezixhobo ezitsha ngundoqo kwi-teknoloji entsha kwixesha elitsha, ukubonelela ngendlela entsha yokukhusela imo engqongileyo kunye nokugcina amandla, kwaye ihambelana ngokusondeleyo noqoqosho lwelizwe kunye nesimanje. Izixhobo zetsimbi ezinogwebu azinayo nje impawu zobunzima bokukhanya ukuba izinto eziqhelekileyo ze-porous, kodwa zineempawu ezibalaseleyo zoomatshini kunye neempawu ezibonakalayo ezifana nobushushu kunye nombane, kwaye kulula ukuhlaziya ngaphezu kwamagwebu e-polymeric, ukwandisa uluhlu lwesicelo sezinto eziphathekayo. Kwiminyaka yakutshanje, uphuhliso lwetekhnoloji entsha luye lwaphucula kakhulu umgangatho wesinyithi esinamagwebu, kwaye iimeko zokusetyenziswa kwezinto ezintsha zitshintshile kakhulu. Abantu baqala ukuba nomdla kuphuhliso lwesinyithi esinegwebu, ngakumbi i-alloy aluminium enegwebu. Umzekelo: kwishishini leemoto, ngenxa yokunyuka kwemfuno yokhuseleko kunye nokukhuselwa kwendalo, abantu baqala ukuqwalasela ukusetyenziswa kwesinyithi se-foam.
1. Inkqubo yokulungiselela kunye nophuhliso lwe-foam yensimbi
Inkqubo yokulungiselela i-foam yensimbi iphefumlelwe ngokulungiswa kwe-polymeric foams kwaye iye yaphuhliswa ngakumbi ngenxa yeempawu zayo ezizodwa zetsimbi. Amagwebu esinyithi anokwahlulwa abe ziindidi ezimbini: nge-cell kunye ne-closed-cell ngokwesakhiwo sazo sangaphakathi sepore. Iindlela zokulungiselela zinokushwankathelwa ngolu hlobo lulandelayo:
I-Metal foam yahlulwe ngokwe:
- I-foam yentsimbi evaliweyo yahlulahlulwe yaba yindlela yokunyibilika ugwebu, indlela yomgubo wogwebu, ukongeza indlela yebhola enomgongxo, kunye nendlela yokutshiza.
- Ngomngxuma isinyithi esinogwebu sahlulwe ngendlela yokuphosa, indlela yokutshala imali, indlela ye-sintering kunye nendlela yokubeka isinyithi.
2. Iimpawu zesinyithi se-foam
Amagwebu esinyithi abonisa iimpawu ezinomdla ngenxa yesakhiwo sazo esine-porous, ukudibanisa iimpawu zesiseko sesinyithi kunye nesakhiwo sayo.
Njengezinto zokwakha, iipropathi zomatshini ze-foam yensimbi zixhomekeke ikakhulu kubuninzi bayo kunye neempawu zesiseko sesinyithi. Umzekelo, igwebu lesinyithi elinoxinaniso oluphezulu nalo lunamandla acinezelayo aphezulu, kwaye igwebu lesinyithi elinamandla amakhulu e-matrix nalo linamandla acinezelayo aphezulu.
Njengemathiriyeli esebenzayo, ineempawu ezahlukeneyo zomzimba ezinje ngokufunxa isandi, ukuhluzwa, ukugquma ubushushu, ukubuyiswa komlilo, ukunciphisa i-vibration, ukudambisa, ukufunxa amandla, kunye nokukhusela i-electromagnetic.
Phakathi kwabo, eyona nto ifundwayo kwaye isetyenziswa ngokubanzi kukufunxa amandla e-foam yensimbi.
3. Ukusetyenziswa kwesinyithi se-foam
Ukusetyenziswa kuxhomekeke ekusebenzeni, kunye nokusebenza okugqwesileyo kwesinyithi se-foam kugqiba uluhlu lwayo olubanzi lokusetyenziswa.
Okwangoku, ezinye iipropathi zesinyithi sogwebu zisetyenzisiwe eJapan. Umzekelo, iipropathi zokufunxa isandi zogwebu lwe-aluminium zisetyenziswa kumagumbi okuvelisa amandla koololiwe bokubona indawo baseHokkaido kunye nezixhobo zokunciphisa ingxolo kwiifektri, izihlalo zikaloliwe zeJR Shinkansen zisebenzisa ubume obudibeneyo be-aluminium foam, kunye neempawu ezizodwa zokuhombisa. umphezulu we-foam nawo asetyenziswa kwizakhiwo. Ishishini.
Nge-pore metal foams zisetyenziswa njengezixhobo zokucoca, ukutshintshiselana kobushushu, izihluzi kunye nenkxaso ye-catalyst, kwaye zikwasetyenziswa njengezinto ze-electrode.
