Screen zvinhu zvinonyanya kushandiswa kusefa pamusoro uye zvinonzwika zvinhu zvinoshandiswa pakadzika kusefa.Misiyano yacho ndeiyi:
1. Chidzitiro (nylon monofilament, metal monofilament) inobata zvakananga kusvibiswa mukusefa pamusoro pechinhu.Zvakanakira ndezvokuti chimiro che monofilament chinogona kucheneswa kakawanda uye mutengo wekushandisa wakaderera;Asi iyo yakashata inzvimbo yekusefa modhi, iyo iri nyore kukonzera kuvharika kwepamusoro kwebhegi resefa.Rudzi urwu rwechigadzirwa rwakanyanya kukodzera nguva dzakaomarara dzekusefa nekudzika kwakadzika, uye iyo yekusefa chaiko ndeye 25-1200 μ m.
2. Felt material (tsono yakabayiwa jira, mhinduro inoputika jira risiri rakarukwa) inowanzoitika yakadzika matatu-dimensional filter material, iyo inoratidzirwa nekusununguka kwefiber structure uye yakakwirira porosity, iyo inowedzera kukwanisa kwetsvina.Rudzi urwu rwefiber material ndeyemukomboni interception mode, kureva kuti, zvimedu zvihombe zvetsvina zvinopindirwa pamusoro pefayibha, nepo zvimedu zvinyoro zvakavharirwa muchikamu chakadzika chesefa, saka kusefa kune yakakwirira kusefa. kushanda zvakanaka, Mukuwedzera, kupisa kwepamusoro kwepamusoro kwekushisa kwekushisa, ndiko kuti, kushandiswa kwekombiyuta yekukurumidza sintering, inogona kudzivirira zvinobudirira kuti fiber irege kurasikirwa nekuda kwekukurumidza-kumhanya kwemvura panguva yekusefa;Iyo yakanzwa zvinhu inoraswa uye iko kurongeka kwesefa ndeye 1-200 μ m.
Iyo huru yezvinhu zvimiro zvesefa zvinonzwika ndezvizvi:
Polyester - iyo inonyanya kushandiswa sefa fiber, yakanaka makemikari kuramba, kushanda tembiricha isingasviki 170-190 ℃.
Polypropylene inoshandiswa kusefa yemvura muindasitiri yemakemikari.Iyo ine yakanakisa asidhi uye alkali kuramba.Kupisa kwayo kwekushanda kuri pasi pe100-110 ℃
Wool - yakanaka anti solvent basa, asi haina kukodzera anti acid, alkali kusefa
Nilong ine yakanaka makemikari kuramba (kunze kweasidhi kuramba), uye tembiricha yayo yekushanda iri pasi pe170-190 ℃.
Fluoride ine basa rakanakisa rekudzivirira tembiricha uye makemikari kuramba, uye tembiricha yekushanda iri pasi pe250-270 ℃.
Kuenzanisa kwezvakanakira uye zvakaipira pakati pepamusoro sefa zvinhu uye yakadzika sefa zvinhu
Kune mhando dzakawanda dzemasefa zvinhu zvemasefa.Zvakadai seyakarukwa waya mesh, sefa bepa, simbi jira, sintered sefa chinhu uye akanzwa, etc. Zvisinei, maererano ayo kusefa nzira, inogona kukamurwa kuva mhando mbiri, kureva pamusoro pemhando uye kudzika mhando.
1. Surface sefa zvinhu
Surface type filter material inonziwo absolute filter material.Kumusoro kwayo kune imwe geometry, yunifomu micropores kana chiteshi.Inoshandiswa kubata tsvina mumafuta ekuvharira.Iyo sefa zvinhu zvinowanzo chena kana twill sefa yakagadzirwa nesimbi waya, jira faibha kana zvimwe zvinhu.Kusefa kwayo kwakafanana nekushandiswa kweiyo chaiyo skrini.Kurongeka kwayo kwesefa kunoenderana nehukuru hwejometri ye micropores uye chiteshi.
Zvakanakira zvemhando yepamusoro sefa zvinhu: kutaura kwakaringana kwechokwadi, kuwanda kwekushandisa.Zviri nyore kuchenesa, kushandiswazve, hupenyu hurefu hwebasa.
Izvo zvisingabatsiri zvemhando yepamusoro sefa zvinhu ndezvizvi: shoma shoma yekusvibisa;Nekuda kwekudzikisira kwehunyanzvi hwekugadzira, iyo chaiyo iri pasi pe10um
2. Deep sefa zvinhu
Depth type filter material inonziwo deep type filter material kana yemukati type filter material.Iyo sefa zvinhu ine imwe ukobvu, iyo inogona kunzwisiswa seyepamusoro peakawanda emhando mhando mafirita.Iyo yemukati chiteshi inoumbwa isina yakajairwa uye isina chaiyo saizi yeyakadzika gap.Kana mafuta achipfuura nepasefa zvinhu, tsvina iri muoiri inobatwa kana kushambadzwa pakadzika kwakasiyana kwesefa zvinhu.Kuti uite basa rekusefa.Sefa bepa ndeye yakajairika yakadzika sefa zvinhu zvinoshandiswa mu hydraulic system.Kurongeka kunowanzova pakati pe3 ne20um.
Zvakanakira zvemhando yakadzika sefa zvinhu: yakawanda tsvina, hupenyu hurefu hwesevhisi, inokwanisa kubvisa zvidimbu zvidiki pane iyo chaiyo uye tambo, yakakwirira kusefa chaiko.
Kuipa kwekudzika mhando sefa zvinhu: hapana yunifomu saizi yekusefa zvinhu gap.Ukuru hwezvimedu zvetsvina hazvigone kudzorwa nemazvo;Zvinenge zvisingabviri kuchenesa.Zvizhinji zvacho zvinoraswa.Kudyiwa kwakakura.
