Muzviitiko zvemafekitari workshops, migodhi, kana kufambiswa kwemagetsi, kune rudzi rwepombi "isingazivikanwe" gore rose asi inotakura mitoro inorema - vanowanzo takura midhiya ine zvinhu zvine simba zveabrasion zvakaita sejecha, slurry, upfu hwemarasha, nezvimwewo Kubuda kwesilicon carbide kupfeka-resistant pombindiko kunyatsogadzirisa dambudziko iri remaindasitiri, richiva muchengeti we "hard core" munzvimbo dzakaoma dzekufambisa.
Chii chinonzi silicon carbide kupfeka-resistant pombi?
Zvichitaurwa zviri nyore, silicon carbide kupfeka-inodzivirira pombi mapaipi ekutakura anogadzirwa nekubatanidza silicon carbide sechinhu chepakati chinodzivirira zvinhu nemapombi esimbi (senge pombi dzesimbi) kuburikidza nemaitiro akakosha.
Mumwe munhu angabvunza, chii chinonzi silicon carbide? Icho chinhu chakagadzirwa chakagadzirwa inorganic isiri-simbi ine kuomarara kwakanyanya, yechipiri chete kune diamond. Mazhinji sandpaper nemavhiri ekukuya atinoona muhupenyu hwezuva nezuva anogadzirwa nesilicon carbide. Kushandisa yakadaro 'kupfeka-inodzivirira nyanzvi' kugadzira mukati memapaipi kunogona kuvapa kwakasimba kusakara kwakasimba.
Kuenzaniswa nemapombi esimbi echinyakare uye pombi dzakakandwa dzematombo, iyo yakakosha mukana wesilicon carbide inodzivirira mapombi ari mu "zvemukati nekunze kugadzirisa": iyo yemukati silicon carbide layer ine basa rekudzivisa kukukurwa uye kupera kwepakati, nepo yekunze simbi layer inovimbisa kusimba kwese uye kumanikidza kwepombi. Iko kusanganiswa kwezviviri hakugadzirisi chete dambudziko rekuramba kupfeka, asi rinofungawo nezvekuchengetedzwa uye kuvimbika kwekushandiswa kwemaindasitiri.
Sei ichigona 'kumira' nharaunda dzakaoma?
Kusimba kwesilicon carbide kupfeka-resistant pombi zvinonyanya kunobva kune hunhu hwesilicon carbide zvinhu pachayo:
Ultra yakasimba kupfeka kuramba: Sezvambotaurwa, silicon carbide ine kuomarara kwakanyanya, uye kupfeka kwayo kwepamusoro kunononoka pakutarisana nekunyungudika kwenguva refu kubva kune granular media senge slurry nejecha. Kuenzaniswa nemapombi esimbi akajairwa, hupenyu hwavo hwesevhisi hunogona kuwedzerwa kanoverengeka kana kanopfuura kagumi, zvichideredza zvakanyanya kuwanda uye mutengo wekutsiva pombi.
Kuramba tembiricha yakakwira uye yakaderera uye kushorwa kwekuora: Pamusoro pekupfeka kuramba, silicon carbide inogona zvakare kuchinjika kune yakakura tembiricha renji, uye inogona kushanda zvakatsiga munzvimbo dzinobva paminus makumi emadhigirii Celsius kusvika kumazana emadhigirii celsius. Panguva imwecheteyo, inewo kupikisa kwakanaka kune zvinosvibisa media zvakadai seasidhi uye alkali, iyo inoita kuti "ikwanise" mumamiriro ezvinhu akaoma ekufambisa mumaindasitiri akadai semakemikari uye metallurgical.
Kubudirira kwekufambisa kwakagadzikana: Nekuda kwekutsetseka kwepamusoro pesilicon carbide lining, kuramba kwepakati inoyerera mupombi kwakadzikira, zvichiita kuti isanyanya kuvharika. Izvi hazvirevi chete kugadzikana kwekufambisa kwekufambisa, asiwo kunoderedza nguva yekuderera kunokonzerwa nekuchenesa pombi.
Inoratidzira hunyanzvi hwayo kupi?
Kunyangwe ichinzwika se "nyanzvi", kushandiswa kwesilicon carbide kusagadzika pombi kuri padyo zvakanyanya nekugadzirwa kwedu uye hupenyu:
Mumigodhi uye metallurgical maindasitiri, inoshandiswa kutakura mineral slurry kubva kumigodhi uye tsvina yakasara kubva mukunyungudutswa, uye inoiswa pasi pekupfeka kwakanyanya uye kubvarura kubva kune yakakwira conticulate media;
Muindasitiri yemagetsi, iyo pombi yakakosha yekutakura hupfu hwemarasha mumagetsi emagetsi ekupisa, kuve nechokwadi chekupihwa kwakagadzikana kwemafuta ebhailer;
Muzvivakwa zvekuvaka uye maindasitiri emakemikari, inogona kutakura simende zvigadzirwa, makemikari zvigadzirwa, nezvimwewo, kutarisana nekupfeka uye kushomeka kushoma kwe media dzakasiyana.
Zvinogona kutaurwa kuti mune chero indasitiri yeindasitiri inoda kutakurwa kwenhau ine yakasimba kupfeka kuramba uye yakaoma mamiriro ekushanda, kuvapo kwesilicon carbide kupfeka-resistant mapaipi kunogona kuonekwa. Inopa vimbiso dzakakosha dzekuenderera uye kushanda kwakanaka kwekugadzirwa kwemaindasitiri nekuita kwayo "hardcore", uye yavewo chikamu chakakosha chemazuva ano ekufambisa maindasitiri masisitimu.
