A porous sintered sefaimhando yesefa inogadzirwa ne sintering (heating and compressing) poda kana zvidimbu pamwechete kuita chinhu chakasimba chine porous structure. Aya mafirita anoshandiswa mumhando dzakasiyana dzekushandisa, kusanganisira kusefa, kupatsanura, uye kucheneswa. Izvo zvakagadzirwa nezvinhu zvakasiyana-siyana sesimbi isina tsvina, aluminium uye bronze. Iyo porous chimiro inobvumira zvinwiwa kana magasi kuti apfuure apo uchiteya nekubvisa zvidimbu zvisingadiwe kana tsvina. Iyo pore saizi uye kugovera, pamwe neiyo zvinhu zvivakwa, inogona kugadziriswa kuti ienderane neyakananga kusefa application. Aya mafirita anozivikanwa nekusimba kwawo, kukwira-tembiricha kuramba, uye kuenderana kwemakemikari, uye anowanzo shandiswa mukuda maindasitiri nesainzi mashandisirwo.
Asi pane akasiyana sintered mafirita zvinhu pamusika, isu tingasiyanise sei yakanaka sintered sefa zvinhu?
II. Tsanangudzo ye sintered metal filters
ZvadaroChii chinonzi sintered metal filters?
Sintered simbi mafirita akakosha mune akawanda maindasitiri uye ekutengesa maapplication, kubva kumvura kusefa kusvika kucheneswa gasi. Zvisinei, haasi ese mafirita esintered esimbi anogadzirwa akaenzana. Izvo zvakakosha kusiyanisa emhando yepamusoro sintered simbi mafirita kubva kune ayo emhando yakaderera kuti ave nechokwadi chekuti anozoita sezvaitarisirwa uye anogara kwenguva yakareba. Mune ino blog post, isu tichakurukura maitiro emhando yepamusoro sintered simbi mafirita, nzira dzekuongorora mhando yemasefa esimbi akaiswa, uye kukosha kwekusarudza mafirita emhando yepamusoro.
III.Kukosha kwekuziva mafirita emhando yepamusoro
I.Chekutanga, ngatitsanangurirei kuti sintered metal sefa chii.
Sintered metal mafirita anogadzirwa nekukochekera simbi poda kuita chimiro chakafanogadzirwa uye wobva adziisa kusvika patembiricha iri pazasi penzvimbo yekunyungudika. Kuita uku, kunonzi sintering, kunoita kuti zvidimbu zvesimbi zvibatane, zvichiita kuti chimedu chakasimba chine porous structure. Iyo pore saizi uye porosity yesefa inogona kudzorwa nekugadzirisa saizi uye chimiro chesimbi zvidimbu uye sintering mamiriro. Iyo porous chimiro chesefa inobvumira mvura kana gasi kuti ipfuure nepo ichiteya zvisingadiwe.
II. Hunhu hweHigh-Quality Sintered Metal Filters
Zvino, ngatikurukurei hunhu hwemhando yepamusoro sintered metal sefa. Yepamusoro-soro sintered simbi sefa inofanira kuva inowirirana uye yakafanana pore saizi uye yakakwirira porosity. Izvi zvinova nechokwadi chekuti sefa inogona kuteya zvimedu zvinodikanwa uku ichibvumira mvura kana gasi kuti ipfuure nekudzivirirwa kushoma. Yepamusoro-soro sintered simbi mafirita anofanirwawo kuve neakakwira mechanical simba, kumirisana nekumanikidza kwakanyanya uye kuramba deformation. Pamusoro pezvo, dzinofanirwa kuenderana nekemikari, dzirambe dziine ngura uye makemikari mazhinji, uye dzikwanise kushivirira tembiricha yakakwira pasina kurasikirwa nehunhu.
A. Porous chimiro:
Inopindirana uye yakafanana saizi yepore: Porous sintered mafirita ane inowirirana uye yakafanana pore saizi mukati mesesefa chinhu. Inobvumira kunyatso kudzora pamusoro pekusefa kwechinhu.
Yakakwira porosity: Iyo porous chimiro che sintered sefa zvinhu inobvumira kuyerera kwakakwira uye tsvina-inobata simba.
B. Mechanical simba:
Yakakwira kuramba kudzvanywa: Sintered mafirita zvinhu zvine yakakwira kuramba kudzvanywa uye inogona kumirisana nepamusoro-kudzvanywa musiyano pasina kukanganisa kana kukuvara.
Inopikisa deformation: Sintered filter element dzinozivikanwa nepamusoro pesimba remuchina uye kusimba, zvichiita kuti dzive dzakakodzera kushandiswa munzvimbo dzine hutsinye uye dzikwanise kumirisana nedzvinyiriro yakanyanya pasina kukanganisa.
C. Chemical kuenderana:
Inodzivirira kune corrosion: Sintered sefa zvinhu zvinowanzogadzirwa kubva kuzvinhu zvisingaite corrosion, zvichiita kuti zvikodzere kushandiswa munzvimbo dzinoora.
Inopokana nemakemikari mazhinji: Sintered sefa zvinhu zvinogadzirwawo kubva kuzvinhu zvinopokana neakasiyana siyana emakemikari, zvichiita kuti ive yakakodzera kushandiswa kwemakemikari kusefa.
D. Temperature tolerance:
Inokwanisa kumira tembiricha yakakwira: Sintered sefa zvinhu zvinokwanisa kumira tembiricha yakakwira pasina kurasikirwa nekutendeseka kwavo kana kusefa.
Inokwanisa kuchengetedza kutendeseka kwechimiro: Sintered mafirita zvinhu zvinogona kuchengetedza kutendeseka kwavo kwechimiro kunyangwe painenge ichiratidzwa kune yakanyanya tembiricha. Inoita kuti dzive dzakakodzera kushandiswa mune yakakwirira-tembiricha application senge furnace filtration.
IV.Nzira dzeKuongorora Hunhu hweSintered Metal Filters
Nzira dzinoverengeka dzinogona kushandiswa kuongorora kunaka kwemasefa esimbi ane sintered. Imwe nzira ndeyekuongorora kwemuviri, iyo inosanganisira kuongorora nekuona chimiro cheporous uye kuyera saizi yepore. Imwe nzira ndeyeyemechani yekuyedza, sekumanikidza kudonha uye kuputika kwesimba kuyedzwa. Kemikari kuenderana kuyedzwa, senge corrosion kuramba uye makemikari kuramba kuyedza, inogona zvakare kushandiswa kuongorora kunaka kwemafirita. Chekupedzisira, kuyedzwa kwetembiricha, kunosanganisira kukwira-tembiricha kuyedzwa uye kupisa bhasikoro kuyedzwa, kunogona kushandiswa kuve nechokwadi chekuti mafirita achaita nemazvo mune yakarongwa application.
A. Kuongororwa Kwenyama:
Kuongorora kwekuona kwechimiro cheporous: Iyi mhando yekuyedza inosanganisira kutarisa sefa zvinhu pasi pemaikorosikopu kana chimwe chigadziriso chekukudza kuti ive nechokwadi chekuti porous chimiro chinowirirana uye chisina hurema.
Kuyera saizi yepore: Izvi zvinosanganisira kushandisa midziyo yakasarudzika kuyera saizi yemapores mune sefa zvinhu. Ruzivo urwu runogona kushandiswa kuve nechokwadi chekuti sefa inokwanisa kunyatso bvisa zvimedu zvinodiwa kubva mumvura.
B. Mechanical Testing:
Kuyedza kudonhedza bvunzo: Iyi mhando yekuyedza inoyera kudonhedza kudonhedza pasi pesefa zvinhu pasi pemamiriro akasiyana, sekusiyana kwemazinga ekuyerera kana marudzi akasiyana ezvimedu mumvura. Ruzivo urwu runogona kushandiswa kuona kushanda kwesefa uye kuona chero zvingangoitika nekuita kwesefa.
Burst simba kuyedzwa: Muedzo uyu unoyera yakanyanya kudzvanywa sefa inogona kumira isati yatadza.
C. Chemical kuenderana kuyedzwa:
Corrosion kuramba kuyedza: Iyi mhando yekuyedza inoshandiswa kuona kuti mafirita anogona sei kuramba corrosion kana akafumurwa kune akasiyana marudzi emakemikari. Ruzivo urwu runogona kushandiswa kuve nechokwadi chekuti sefa inokwanisa kushanda nemazvo munzvimbo inodiwa.
Kemikari kuramba kuyedzwa: Muedzo uyu unoyera kusefa zvinhu kupokana nemakemikari nekuiisa kune chaiyo kemikari uye kuyera shanduko mune sefa zvinhu.
D. Kuyedza tembiricha:
Kuyedza tembiricha yepamusoro: Iyi mhando yekuyedza inosanganisira kufumura mafirita kune tembiricha yakakwira kuti ive nechokwadi chekuti inogona kumirisana nematembiricha ayo anogona kuratidzwa mukushandiswa kwayo.
Kupisa bhasikoro kuyedzwa: Iyi mhando yekuyedza inosanganisira kudzokorodza kufumura mafirita kune ese ari maviri epamusoro uye akadzika tembiricha kuti ive nechokwadi chekuti inogona kumira yakadzokororwa yekupisa kusagadzikana pasina kutadza.
Zvakakosha kusarudza emhando yepamusoro sintered simbi mafirita nekuda kwezvikonzero zvakawanda. Chekutanga, mafirita emhando yepamusoro achaita zvirinani uye anogara kwenguva refu pane akaderera-mhando. Izvi zvinoreva kuti ivo vanozoda kushoma kazhinji kutsiva uye kugadzirisa, izvo zvinogona kuchengetedza nguva nemari mukufamba kwenguva. Masefa emhando yepamusoro anozotadzawo kutadza, kudzivirira kudhura nguva yekudzikira uye kukuvara kwemidziyo. Pamusoro pezvo, mafirita emhando yepamusoro anozokwanisa kuchengetedza michina uye maitiro aanoshandiswa mazviri, izvo zvinogona kuvandudza kugona kwese uye kushanda kwekushanda.
V. Mhedziso
Mukupedzisa, sintered simbi mafirita akakosha mune akawanda maindasitiri uye ekutengesa maapplication. Izvo zvakakosha kusiyanisa emhando yepamusoro sintered simbi mafirita kubva kune ayo emhando yakaderera kuti ave nechokwadi chekuti anozoita sezvaitarisirwa uye anogara kwenguva yakareba. High-quality sintered metal mafirita anofanirwa kunge ane saizi inowirirana uye yakafanana pore, yakakwirira porosity, yakakwirira mechanical simba, makemikari kuenderana, uye tembiricha kushivirira. Nzira dzinoverengeka dzinogona kushandiswa kuongorora kunaka kwesimbi yakanyungudutswa mafirita, kusanganisira kuongorora kwemuviri, bvunzo dzemakanika, kuyedzwa kwekuenderana kwemakemikari, uye kuyedzwa kwekushisa. Kusarudza emhando yepamusoro sintered simbi mafirita anogona kuchengetedza nguva nemari mukufamba kwenguva uye kunatsiridza kugona kwese uye kushanda kwekushanda.
